66-629: The Rift went through various pre-production models prior to the release of the Oculus Rift CV1, the first Oculus Rift intended for use by the general public. Two of these, the DK1 in early-2013 and DK2 in mid-2014, were intended to provide content developers with a development kit platform to create content for the Rift's eventual consumer release. However, both development kits were purchased by many gaming enthusiasts who wished to get an early preview of

132-486: A $ 200,000 camera rig to produce 360° 3D content for the Rift, including short films, as well as live streaming live events such as sports or concerts in 360° 3D. In July 2015, Oculus announced a deal with Canadian film company Felix & Paul Studios to produce 360° 3D videos for the Rift. The Rift also supports a new medium of entertainment experiences, which Oculus calls "virtual reality movies". Oculus has established Oculus Story Studio to develop this type of content for

198-522: A 1080×1200 resolution, running at 90 Hz, 360-degree positional tracking, integrated audio, a vastly increased positional tracking volume, and a heavy focus on consumer ergonomics and aesthetics. In March 2019, during the announcement of the Rift S, it was said that the Rift S would replace the original Rift. However, Oculus VR stated that they planned to support the CV1 with software updates for "the foreseeable future". On May 21, 2019, Oculus began shipping

264-420: A GeForce GTX 960 or equivalent graphics card, two USB 3.0 ports and one USB 2.0 port, and Windows 8 or newer. The company stated that these lower requirements were enabled by the adoption of motion interpolation ; on systems that cannot handle full 90 frames per second rendering, the drivers will allow software to render at 45 FPS instead, and generate frames based on differences between them to send to

330-535: A combination of three-axis gyros , accelerometers , and magnetometers , which make it capable of absolute (relative to Earth) head orientation tracking without drift. The Development Kit 1 also included interchangeable lenses that aim to allow for simple dioptric correction . The entire source for the Rift DK1 was released to the public in September 2014, including the firmware, schematics, and mechanicals for

396-507: A high[-]quality consumer-level VR experience"; support for Linux and macOS will be developed in the future. A hardware testing application is available, and Oculus VR has also certified and promoted specific models of pre-built computers that meet these recommendations, from vendors such as Asus , Alienware and Dell Inc. , as being "Oculus Ready". On October 6, 2016, Oculus VR announced lessened hardware recommendations, now suggesting an Intel Core i3-6100 or AMD FX 4350 CPU, at least

462-2241: A lens not being perfectly aligned. The latter is also known as decentering distortion . See Zhang for additional discussion of radial distortion. The Brown-Conrady distortion model is x u = x d + ( x d − x c ) ( K 1 r 2 + K 2 r 4 + ⋯ ) + ( P 1 ( r 2 + 2 ( x d − x c ) 2 ) + 2 P 2 ( x d − x c ) ( y d − y c ) ) ( 1 + P 3 r 2 + P 4 r 4 ⋯ ) y u = y d + ( y d − y c ) ( K 1 r 2 + K 2 r 4 + ⋯ ) + ( 2 P 1 ( x d − x c ) ( y d − y c ) + P 2 ( r 2 + 2 ( y d − y c ) 2 ) ) ( 1 + P 3 r 2 + P 4 r 4 ⋯ ) , {\displaystyle {\begin{alignedat}{3}x_{\mathrm {u} }=x_{\mathrm {d} }&+(x_{\mathrm {d} }-x_{\mathrm {c} })(K_{1}r^{2}+K_{2}r^{4}+\cdots )+(P_{1}(r^{2}+2(x_{\mathrm {d} }-x_{\mathrm {c} })^{2})\\&+2P_{2}(x_{\mathrm {d} }-x_{\mathrm {c} })(y_{\mathrm {d} }-y_{\mathrm {c} }))(1+P_{3}r^{2}+P_{4}r^{4}\cdots )\\y_{\mathrm {u} }=y_{\mathrm {d} }&+(y_{\mathrm {d} }-y_{\mathrm {c} })(K_{1}r^{2}+K_{2}r^{4}+\cdots )+(2P_{1}(x_{\mathrm {d} }-x_{\mathrm {c} })(y_{\mathrm {d} }-y_{\mathrm {c} })\\&+P_{2}(r^{2}+2(y_{\mathrm {d} }-y_{\mathrm {c} })^{2}))(1+P_{3}r^{2}+P_{4}r^{4}\cdots ),\end{alignedat}}} where Barrel distortion typically will have

528-1279: A negative term for K 1 {\displaystyle K_{1}} whereas pincushion distortion will have a positive value. Moustache distortion will have a non- monotonic radial geometric series where for some r {\displaystyle r} the sequence will change sign. To model radial distortion, the division model typically provides a more accurate approximation than Brown-Conrady's even-order polynomial model, x u = x c + x d − x c 1 + K 1 r 2 + K 2 r 4 + ⋯ y u = y c + y d − y c 1 + K 1 r 2 + K 2 r 4 + ⋯ , {\displaystyle {\begin{aligned}x_{\mathrm {u} }&=x_{\mathrm {c} }+{\frac {x_{\mathrm {d} }-x_{\mathrm {c} }}{1+K_{1}r^{2}+K_{2}r^{4}+\cdots }}\\y_{\mathrm {u} }&=y_{\mathrm {c} }+{\frac {y_{\mathrm {d} }-y_{\mathrm {c} }}{1+K_{1}r^{2}+K_{2}r^{4}+\cdots }},\end{aligned}}} using

594-461: A new VR headset known as Rift S. The Rift S has a 1,280 ×1,440 LCD @ 80 Hz and slightly larger field of view than that of the CV1, but lacks mechanical IPD adjustment (IPD adjustment is software-only). The Rift S tracks the position of itself and its controllers in 3D space using a system known as Oculus Insight, which uses the 5 cameras on the HMD to track points in the environment and infrared LEDs on

660-471: A new motion tracking system that utilized an external camera to track infrared dots located on the headset. The new motion tracking system would allow the system to detect actions such as leaning or crouching, which was claimed to help alleviate sickness experienced by users when the software did not respond to these actions. Oculus began shipping Development Kit 2 (DK2) in July 2014. This is a small refinement of

726-575: A platform-specific app. For example, the development of an Android app on the Java platform requires a Java Development Kit . For iOS applications (apps) the iOS SDK is required. For Universal Windows Platform the .NET Framework SDK might be used. There are also SDKs that add additional features and can be installed in apps to provide analytics, data about application activity, and monetization options. Some prominent creators of these types of SDKs include Google, Smaato, InMobi, and Facebook. An SDK can take

792-413: A prototype Oculus Rift. Carmack wrote a public review of the prototype calling it "by far the most immersive HMD " he had used, noting that the targeted price would also make it the cheapest. At the 2012 Electronic Entertainment Expo , Id Software gave demonstrations of their games running on the prototype Oculus Rift and announced that their newest game, Doom 3 BFG Edition , would be compatible with

858-413: A sense of a scene being deep or shallow. This cannot be changed or corrected by a simple transform of the resulting image, because it requires 3D information, namely the depth of objects in the scene. This effect is known as perspective distortion ; the image itself is not distorted but is perceived as distorted when viewed from a normal viewing distance. Note that if the center of the image is closer than

924-483: A spherical-mapped image for each eye. Initial prototypes used a Hillcrest Labs 3DoF head tracker that is normally 125 Hz, with a special firmware requested by John Carmack that makes it run at 250 Hz, tracker latency being vital due to the dependency of virtual reality's realism on response time. The latest version includes Oculus's new 1000 Hz Adjacent Reality Tracker, which aims to provide much lower latency tracking than almost any other tracker. It uses

990-479: A table of lens/camera transfer functions: Manual software allows manual adjustment of distortion parameters: Besides these systems that address images, there are some that also adjust distortion parameters for videos: Radial distortion is a failure of a lens to be rectilinear : a failure to image lines into lines. If a photograph is not taken straight-on then, even with a perfect rectilinear lens, rectangles will appear as trapezoids : lines are imaged as lines, but

1056-417: A wide stereoscopic field-of-view that would come to define all of his subsequent designs. Luckey decided to drop out of college and start Oculus VR , intending to turn his prototype into the world's first mass-produced virtual reality headset. Noted videogame pioneer John Carmack , the founder of id Software , had been doing extensive research into virtual reality technology, leading Luckey to lend him

1122-410: Is 1280×800 (16:10 aspect ratio), which leads to an effective of 640×800 per eye (4:5 aspect ratio). However, since the device does not feature a 100% overlap between the eyes, the combined horizontal resolution is effectively greater than 640. The image for each eye is shown in the panel as a barrel distorted image that is then corrected by pincushion effect created by lenses in the headset, generating

1188-492: Is a collection of software development tools in one installable package. They facilitate the creation of applications by having a compiler, debugger and sometimes a software framework . They are normally specific to a hardware platform and operating system combination. To create applications with advanced functionalities such as advertisements, push notifications, etc; most application software developers use specific software development kits. Some SDKs are required for developing

1254-407: Is a deviation from rectilinear projection ; a projection in which straight lines in a scene remain straight in an image. It is a form of optical aberration that may be distinguished from other aberrations such as spherical aberration , coma , chromatic aberration , field curvature , and astigmatism in a sense that these impact the image sharpness without changing an object shape or structure in

1320-492: Is dominant, while at the edge the degree 4 distortion in the pincushion direction dominates. Other distortions are in principle possible – pincushion in center and barrel at the edge, or higher order distortions (degree 6, degree 8) – but do not generally occur in practical lenses, and higher order distortions are small relative to the main barrel and pincushion effects. The names for these distortions come from familiar objects which are visually similar. In photography, distortion

1386-478: Is non-trivial due to the non-linearity of the distortion equation. Lateral chromatic aberration (purple/green fringing) can be significantly reduced by applying such warping for red, green and blue separately. Distorting or undistorting requires either both sets of coefficients or inverting the non-linear problem which, in general, lacks an analytical solution. Standard approaches such as approximating, locally linearizing and iterative solvers all apply. Which solver

1452-473: Is observed particularly on the wide end of zooms, with certain retrofocus lenses, and more recently on large-range zooms such as the Nikon 18–200 mm. A certain amount of pincushion distortion is often found with visual optical instruments, e.g., binoculars , where it serves to counteract the globe effect . In order to understand these distortions, it should be remembered that these are radial defects;

1518-521: Is particularly associated with zoom lenses , particularly large-range zooms, but may also be found in prime lenses, and depends on focal distance – for example, the Canon EF 50mm f / 1.4 exhibits barrel distortion at extremely short focal distances. Barrel distortion may be found in wide-angle lenses, and is often seen at the wide-angle end of zoom lenses, while pincushion distortion is often seen in older or low-end telephoto lenses . Mustache distortion

1584-1293: Is preferable depends on the accuracy required and the computational resources available. In addition to usually being sufficient to model most cameras, as mentioned, the single-term division model has an analytical solution to the reverse-distortion problem. In this case, the distorted pixels are given by x d = x c + x u − x c 2 K 1 r u 2 ( 1 − 1 − 4 K 1 r u 2 ) y d = y c + y u − y c 2 K 1 r u 2 ( 1 − 1 − 4 K 1 r u 2 ) , {\displaystyle {\begin{aligned}x_{\mathrm {d} }&=x_{\mathrm {c} }+{\frac {x_{\mathrm {u} }-x_{\mathrm {c} }}{2K_{1}r_{u}^{2}}}(1-{\sqrt {1-4K_{1}r_{u}^{2}}})\\y_{\mathrm {d} }&=y_{\mathrm {c} }+{\frac {y_{\mathrm {u} }-y_{\mathrm {c} }}{2K_{1}r_{u}^{2}}}(1-{\sqrt {1-4K_{1}r_{u}^{2}}}),\end{aligned}}} where Calibrated software works from

1650-534: The App Store . New technologies allow app developers to control and monitor client SDKs in real time. Providers of SDKs for specific systems or subsystems sometimes substitute a more specific term instead of software . For instance, both Microsoft and Citrix provide a driver development kit for developing device drivers . Examples of software development kits for various platforms include: Barrel distortion In geometric optics , distortion

1716-866: The GNU Lesser General Public License are typically usable for proprietary development. In cases where the underlying technology is new, SDKs may include hardware. For example, AirTag 's 2012 near-field communication SDK included both the paying and the reading halves of the necessary hardware stack. The average Android mobile app implements 15.6 separate SDKs, with gaming apps implementing on average 17.5 different SDKs. The most popular SDK categories for Android mobile apps are analytics and advertising. SDKs can be unsafe (because they are implemented within apps yet run separate code). Malicious SDKs (with honest intentions or not) can violate users' data privacy , damage app performance, or even cause apps to be banned from Google Play or

1782-432: The "Crystal Cove" prototype, featuring several key improvements over the first development kit, such as having a higher-resolution (960×1080 per eye) low-persistence OLED display, higher refresh rate of 75   Hz, positional tracking, a detachable cable, and the omission of the need for the external control box. A teardown of DK2 revealed that it incorporates a modified Samsung Galaxy Note 3 smartphone display, including

1848-677: The Development Kit 2 using SDK version 0.8 or above are compatible with the Rift; however, content developed for the Development Kit 1 or with older versions of the SDK will have to be recompiled using the latest SDK version to be compatible. On December 21, 2015, Oculus announced the release of their finalized Rift 1.0 SDK, combined with the start of shipping their final version of the Oculus Rift VR headset to developers. At Oculus's 3rd annual conference (Oculus Connect 3), it announced

1914-423: The Development Kit 2), including Project CARS , Elite: Dangerous , Euro Truck Simulator 2 , and Dirt Rally , as well as a number of indie games such as AaAaAA!!! – A Reckless Disregard for Gravity and Ether One . Fans and hobbyists have also modded support for the Rift into several popular titles which allow for extensive low-level modding , including Minecraft and Flight Simulator X . At

1980-467: The Kickstarter was to get an Oculus Rift prototype—now referred to as DK1 (Development Kit 1)—into the hands of developers to begin integration of the device into their games. The DK1 was given as a reward to backers who pledged $ 300 or more on Kickstarter, and was later sold publicly for $ 300 on their website. These kits sold at a rate of 4–5 per minute for the first day, before slowing down throughout

2046-474: The Oculus Rift. These early prototypes used a high speed IMU , 5.6" LCD , and wide-FOV optics to project a 90 degrees horizontal and 110 degrees vertical stereoscopic 3D view onto the retina of the user. Two months after being formed as a company, Palmer's Oculus VR launched a Kickstarter crowdfunding campaign on August 1, 2012, for their virtual reality headset, named the Rift. The main purpose of

2112-605: The Rift CV1 since. During September 2020, it was announced that the Rift S would be discontinued in 2021 in order for Oculus to focus on the Oculus Quest 2 . In 2021, the Rift S was officially discontinued and was no longer available on the Oculus website, effectively ending the Rift line. The Oculus Rift runtime officially supports Microsoft Windows , macOS , and Linux . The installation package includes components such as

2178-403: The Rift is primarily a gaming device and that their main content focus is gaming. Existing games with a first-person or fixed-camera perspective can be ported to VR with some development effort. However, Oculus has stated that the best virtual reality experiences are those that are designed, from the beginning, for the Rift. A number of AAA games have added Rift support (and can be played with

Oculus Cinema will also have a networked mode, in which multiple users can watch the same video in the same virtual space, seeing each other as avatars and being able to interact and talk to one another while watching

2310-460: The Rift, a team which has multiple former employees from major VFX companies such as PIXAR and ILM . Oculus Story Studio showed off its first VR movie, Lost , at the 2015 Sundance Film Festival , gaining positive reviews from attendees. The studio intends to have 5 VR shorts released with the Rift at launch, including Lost , Bullfighter , Henry , Dear Angelica , and Kabloom . Development kit A software development kit ( SDK )

This is a feature complete SDK which handles for

2442-454: The angles between them are not preserved (tilt is not a conformal map ). This effect can be controlled by using a perspective control lens , or corrected in post-processing. Due to perspective , cameras image a cube as a square frustum (a truncated pyramid, with trapezoidal sides) – the far end is smaller than the near end. This creates perspective, and the rate at which this scaling happens (how quickly more distant objects shrink) creates

2508-623: The base software, called Core 2.0, introduced a more interactive default environment, allowing the user to navigate and customize it with imported 3D models. However in 2023, Meta, formerly known as Oculus, closed Oculus Home and killed it off. Oculus maintains a market place for applications for the headsets. The listings are curated to only allow applications that run smoothly on the recommended hardware. Most listings are also rated on their comfort level based on their likelihood of causing motion sickness or number of jump scares. However, developers do not have to use Oculus Home to distribute content for

The Rift S uses a DisplayPort 1.2 port and one USB 3.0 port, as opposed to the HDMI and USB 3.0 port used on the Rift CV1. The Rift S targeted the same price point (USD$ 399) and hardware requirements as the Rift CV1, and has replaced

2640-677: The developer the various aspects of making virtual reality content, such as the optical distortion and advanced rendering techniques. The Oculus SDK is directly integrated with the popular game engines Unity 5 , Unreal Engine 4 , and Cryengine . This allows for developers already familiar with these engines to create VR content with little to no VR-specific code. The Rift is an open platform, and thus developers do not need any approval or verification to develop, distribute, or sell content for it, and do not have to pay any licensing fees. The SDK, however, cannot be modified or reused for other purposes or hardware without permission. Content developed for

However, radial distortion bends straight lines (out or in), while perspective distortion does not bend lines, and these are distinct phenomena. Fisheye lenses are wide-angle lenses with heavy barrel distortion and thus exhibit both these phenomena, so objects in

2838-521: The first quarter of 2016, and on March 25, 2016, the first batch of headsets began shipping to consumers. In January, 2016, Oculus announced that backers of the original Kickstarter who had pledged $ 275 or more—roughly 7,500 users—would be gifted a free Oculus Rift kit, including the new headset, a game controller, and two VR games. The consumer version is an improved version of the Crescent Bay Prototype, featuring per-eye displays with

Common tools include debugging facilities and other utilities , often presented in an integrated development environment . SDKs may include sample software and/or technical notes along with documentation, and tutorials to help clarify points made by

2970-459: The front panel from the device itself. In February 2015, Oculus announced that over 100,000 DK2 units had been shipped up until that point. In September 2014, Oculus once again presented an updated version of the Rift, codenamed Crescent Bay. This version has a greater resolution than the DK2, a lower weight, built-in audio, and 360-degree tracking thanks to the presence of tracking LEDs in the back of

3036-425: The headset driver (which includes Oculus Display driver and controller drivers), Positional Tracking Sensor driver, Oculus Service, and Oculus Home Application. The runtime service implements a number of processing techniques intended to minimize latency and in addition improve the smoothness of VR applications under weaker hardware. These include direct mode, asynchronous timewarp , and asynchronous spacewarp . When

Oculus promoted that these changes lowered the average hardware cost of a PC meeting these specifications to US$ 500 and would also enable certain laptops to run Oculus Rift. In June 2018, Oculus VR updated its recommended OS spec to Windows 10. While Windows 7 and Windows 8.1 users would still be able to access the standard Rift experience, newer features and apps might require an upgrade to Windows 10. Oculus has stated that

3168-468: The headset. Oculus has also licensed software library RealSpace3D, which is expected to provide the Rift with HRTF and reverb algorithms. During a panel at SXSW 2015 , titled "Explore the Future of VR", it was publicly announced for the first time that the prototype uses two screens instead of one as previously thought. Oculus VR announced on May 6, 2015, that the consumer version of the Rift would ship in

3234-522: The idea of creating a new head-mounted display that was both more effective than what was then on the market, and inexpensive for gamers. The first prototype of the Oculus Rift was created in 2011 by Palmer Luckey (then 18 years old) in his parents’ garage in Long Beach, California . Luckey had been building his own virtual reality headsets since 2009, but the 2011 prototype was the first to incorporate key technologies like geometric pre-distortion and

3300-410: The image (e.g., a straight line in an object is still a straight line in the image although the image sharpness may be degraded by the mentioned aberrations) while distortion can change the object structure in the image (so named as distortion). Although distortion can be irregular or follow many patterns, the most commonly encountered distortions are radially symmetric, or approximately so, arising from

3366-479: The life of the first consumer model. The company also stated that while upcoming discrete GPUs for laptops may be able to reach the required performance for Oculus Rift, systems that switch between integrated and discrete graphics may not handle output in a manner that supports the device. Oculus Rift only supports 64-bit versions of Microsoft Windows 7 SP1 or later; Oculus VR stated that the device would initially support Windows only in order to focus on "delivering

3432-621: The new technology, called "Asynchronous Spacewarp (ASW)". This technology allows the Rift to compensate for the dropped frames. According to Oculus, ASW reduces the minimum specs of a PC to run the Rift without any judder. In May 2015, Oculus VR announced "recommended" hardware specifications for computers utilizing Oculus Rift, specifying a CPU equivalent to an Intel Core i5-4590 , at least 8GB of RAM, at least an AMD Radeon R9 290 or Nvidia GeForce GTX 970 graphics card, an HDMI 1.3 output, three USB 3.0 ports, and one USB 2.0 port. Oculus VR stated that these requirements would remain in force for

3498-567: The optical systems in question have rotational symmetry (omitting non-radial defects), so the didactically correct test image would be a set of concentric circles having even separation – like a shooter's target. It will then be observed that these common distortions actually imply a nonlinear radius mapping from the object to the image: What is seemingly pincushion distortion, is actually simply an exaggerated radius mapping for large radii in comparison with small radii. A graph showing radius transformations (from object to image) will be steeper in

3564-567: The outer parts of the image. This should not be confused with axial (longitudinal) chromatic aberration, which causes aberrations throughout the field, particularly purple fringing . Radial distortion, whilst primarily dominated by low-order radial components, can be corrected using Brown's distortion model, also known as the Brown–Conrady model based on earlier work by Conrady. The Brown–Conrady model corrects both for radial distortion and for tangential distortion caused by physical elements in

3630-411: The primary reference material. SDKs often include licenses that make them unsuitable for building software intended to be developed under an incompatible license. For example, a proprietary SDK is generally incompatible with free software development, while a GNU General Public License 'd SDK could be incompatible with proprietary software development, for legal reasons. However, SDKs built under

3696-457: The release event for the Rift in June 2015, Oculus announced 9 launch titles for the Rift, including EVE: Valkyrie by CCP and Edge of Nowhere by Insomniac Games . It also announced that it was working with other developers including Final Fantasy developer Square Enix , Rock Band developer Harmonix , and The Order: 1886 developer Ready at Dawn . In July 2015, Oculus revealed that it

3762-468: The same parameters previously defined. For radial distortion, this division model is often preferred over the Brown–Conrady model, as it requires fewer terms to more accurately describe severe distortion. Using this model, a single term is usually sufficient to model most cameras. Software can correct those distortions by warping the image with a reverse distortion. This involves determining which distorted pixel corresponds to each undistorted pixel, which

3828-451: The stereoscopic 3D no longer 100% overlapping, the left eye seeing extra area to the left and the right eye seeing extra area to the right, in which there is no 3D depth perception. The field of view (FOV) is more than 90 degrees horizontal (110 degrees diagonal), which is more than double the FOV of previous VR devices from other companies, and is the primary strength of the device. The resolution

3894-403: The symmetry of a photographic lens . These radial distortions can usually be classified as either barrel distortions or pincushion distortions. Mathematically, barrel and pincushion distortion are quadratic , meaning they increase as the square of distance from the center. In mustache distortion the quartic (degree 4) term is significant: in the center, the degree 2 barrel distortion

3960-610: The technology. The Rift saw its official consumer release in March 2016 with the Oculus Rift CV1 , and was eventually replaced in March 2019 by the Oculus Rift S . The Oculus Rift software library is still compatible with its successor, the Oculus Quest . Through Meant to be Seen (MTBS)'s virtual reality and 3D discussion forums , Palmer Luckey , the founder of Oculus and longtime MTBS discussion forum moderator, developed

4026-485: The upper (rightmost) end. Conversely, barrel distortion is actually a diminished radius mapping for large radii in comparison with small radii. A graph showing radius transformations (from object to image) will be less steep in the upper (rightmost) end. Radial distortion that depends on wavelength is called " lateral chromatic aberration " – "lateral" because radial, "chromatic" because dependent on color (wavelength). This can cause colored fringes in high-contrast areas in

An update to

4158-470: The video. The Rift also offers the opportunity to view new types of media that are impossible to view on regular monitors; 360° 3D videos and 'virtual reality movies' (an entirely new medium). Spherical videos (commonly called 360° videos) can be viewed simply by the user moving their head around, and the Rift opens up the possibility for stereoscopic spherical videos (commonly called 360° 3D videos). In September 2014, NextVR announced that they would be using

4224-434: The virtual world more clear, especially at a distance. The poor resolution had been the main criticism of the DK1. This HD prototype is the only prototype of the Rift shown to the public which did not turn into a publicly available developer kit. In January 2014, an updated prototype codenamed "Crystal Cove" was unveiled at Consumer Electronics Show , which used a special low- persistence of vision OLED display as well as

4290-445: The week. The Rift DK1 was released on March 29, 2013, and uses a 7-inch (18 cm) screen with a significantly faster pixel switching speed than the original prototype, reducing latency and motion blur when turning one's head quickly. The pixel fill is also better, reducing the screen door effect and making individual pixels less noticeable. The LCD is brighter and the color depth is 24 bits per pixel.
