109-496: Rave Cinemas, LLC was formed in late 2009 by TowerBrook Capital Partners and investors Lambert Media Group and Charles B Moss, Jr. Rave Cinemas then acquired four properties, corporate infrastructure, and leadership, and the Rave Motion Pictures brand from Boston Ventures owned Rave Reviews Cinemas, LLC (RRC). RRC continues to own 21 other properties which will operate under the "Rave Motion Pictures" branding under

218-448: A backlight or reflector to produce images in color or monochrome . LCDs are available to display arbitrary images (as in a general-purpose computer display) or fixed images with low information content, which can be displayed or hidden: preset words, digits, and seven-segment displays (as in a digital clock) are all examples of devices with these displays. They use the same basic technology, except that arbitrary images are made from

327-454: A refresh operation. Active-matrix addressed displays look brighter and sharper than passive-matrix addressed displays of the same size, and generally have quicker response times, producing much better images. Sharp produces bistable reflective LCDs with a 1-bit SRAM cell per pixel that only requires small amounts of power to maintain an image. Segment LCDs can also have color by using Field Sequential Color (FSC LCD). This kind of displays have

436-631: A 14-inch, active-matrix, full-color, full-motion TFT-LCD. This led to Japan launching an LCD industry, which developed large-size LCDs, including TFT computer monitors and LCD televisions. Epson developed the 3LCD projection technology in the 1980s, and licensed it for use in projectors in 1988. Epson's VPJ-700, released in January 1989, was the world's first compact , full-color LCD projector . In 1990, under different titles, inventors conceived electro optical effects as alternatives to twisted nematic field effect LCDs (TN- and STN- LCDs). One approach

545-493: A Gen 8.5 mother glass, significantly reducing waste. The thickness of the mother glass also increases with each generation, so larger mother glass sizes are better suited for larger displays. An LCD module (LCM) is a ready-to-use LCD with a backlight. Thus, a factory that makes LCD modules does not necessarily make LCDs, it may only assemble them into the modules. LCD glass substrates are made by companies such as AGC Inc. , Corning Inc. , and Nippon Electric Glass . The origin and

654-572: A TN device in the voltage-on state is far less dependent on variations in the device thickness than that in the voltage-off state. Because of this, TN displays with low information content and no backlighting are usually operated between crossed polarizers such that they appear bright with no voltage (the eye is much more sensitive to variations in the dark state than the bright state). As most of 2010-era LCDs are used in television sets, monitors and smartphones, they have high-resolution matrix arrays of pixels to display arbitrary images using backlighting with

763-455: A blue polarizer, or birefringence which gives them their distinctive appearance. STN LCDs have to be continuously refreshed by alternating pulsed voltages of one polarity during one frame and pulses of opposite polarity during the next frame. Individual pixels are addressed by the corresponding row and column circuits. This type of display is called passive-matrix addressed , because the pixel must retain its state between refreshes without

872-608: A brand of Southern Theatres. As part of Southern Theatres' long-term deal with National CineMedia, the Movie Tavern switched from Screenvision to National CineMedia in June 2014. As of December 2016, AMC now owns those former Carmike theatres, some of which are now AMC branded. The company also owned "Rave Digital Media" along with Continental Retail Development, with headquarters in Columbus, Ohio , and operated six properties under

981-541: A corporate lender for small and medium businesses. Investors, including Sunseeker , Ronald Mourad Cohen , Lord Rothschild , and Future Fund , invested a total of $ 580 million in HayFin in September 2010, raising the lender's equity to about €1 billion. TowerBrook sold its stake in HayFin in 2017. In 2010, Towerbrook acquired the building company Monier and sold Broadlane Group for $ 850 million. TowerBrook purchased

1090-419: A dark background. When no image is displayed, different arrangements are used. For this purpose, TN LCDs are operated between parallel polarizers, whereas IPS LCDs feature crossed polarizers. In many applications IPS LCDs have replaced TN LCDs, particularly in smartphones . Both the liquid crystal material and the alignment layer material contain ionic compounds . If an electric field of one particular polarity

The commercially unsuccessful Macintosh Portable (released in 1989) was one of the first to use an active-matrix display (though still monochrome). Passive-matrix LCDs are still used in the 2010s for applications less demanding than laptop computers and TVs, such as inexpensive calculators. In particular, these are used on portable devices where less information content needs to be displayed, lowest power consumption (no backlight ) and low cost are desired or readability in direct sunlight

1308-460: A finely ground powdered pigment, with particles being just 40 nanometers across. The black resist is the first to be applied; this will create a black grid (known in the industry as a black matrix) that will separate red, green and blue subpixels from one another, increasing contrast ratios and preventing light from leaking from one subpixel onto other surrounding subpixels. After the black resist has been dried in an oven and exposed to UV light through

1417-579: A full conversion of existing theaters was completed in August 2007. When Rave Cinemas acquired some theaters from National Amusements in late 2009 and early 2010, they used Barco projectors instead of Christie. With Rave Cinemas now owned by Cinemark, the Christie projectors will be removed and replaced with Barco projectors. At AMC Theatres, the Christie projectors (Barco projectors at Grove City 14) were removed and replaced by Sony 4K Digital Cinema except for

1526-415: A glass substrate to form the cell circuitry to operate the panel. It is usually not possible to use soldering techniques to directly connect the panel to a separate copper-etched circuit board. Instead, interfacing is accomplished using anisotropic conductive film or, for lower densities, elastomeric connectors . Monochrome and later color passive-matrix LCDs were standard in most early laptops (although

1635-514: A grid with vertical wires across the whole screen on one side of the screen and horizontal wires across the whole screen on the other side of the screen. To this grid each pixel has a positive connection on one side and a negative connection on the other side. So the total amount of wires needed for a 1080p display is 3 x 1920 going vertically and 1080 going horizontally for a total of 6840 wires horizontally and vertically. That's three for red, green and blue and 1920 columns of pixels for each color for

1744-412: A high speed passive segment LCD panel with an RGB backlight. The backlight quickly changes color, making it appear white to the naked eye. The LCD panel is synchronized with the backlight. For example, to make a segment appear red, the segment is only turned ON when the backlight is red, and to make a segment appear magenta, the segment is turned ON when the backlight is blue, and it continues to be ON while

1853-449: A layer of molecules aligned between two transparent electrodes , often made of indium tin oxide (ITO) and two polarizing filters (parallel and perpendicular polarizers), the axes of transmission of which are (in most of the cases) perpendicular to each other. Without the liquid crystal between the polarizing filters, light passing through the first filter would be blocked by the second (crossed) polarizer. Before an electric field

1962-624: A leading position in the wristwatch market, like Seiko and its first 6-digit TN-LCD quartz wristwatch, and Casio 's 'Casiotron'. Color LCDs based on Guest-Host interaction were invented by a team at RCA in 1968. A particular type of such a color LCD was developed by Japan's Sharp Corporation in the 1970s, receiving patents for their inventions, such as a patent by Shinji Kato and Takaaki Miyazaki in May 1975, and then improved by Fumiaki Funada and Masataka Matsuura in December 1975. TFT LCDs similar to

2071-617: A management services agreement with Rave Cinemas, LLC. Concurrently with the RRC acquisition, Rave Cinemas, LLC, purchased the business operations and real estate of 35 properties owned by National Amusements, Inc. (NAI) , parent company of Viacom and CBS Corporation . The former NAI assets were rebranded "Rave Motion Pictures" in the second quarter of 2010. In October 2012, Rave Reviews Cinemas, LLC, signed an agreement to sell 16 theaters with 251 screens to Carmike Cinemas for $ 19 million in cash and $ 100.4 million of assumed lease obligations. Of

2180-468: A matrix consisting of electrically connected rows on one side of the LC layer and columns on the other side, which makes it possible to address each pixel at the intersections. The general method of matrix addressing consists of sequentially addressing one side of the matrix, for example by selecting the rows one-by-one and applying the picture information on the other side at the columns row-by-row. For details on

2289-431: A matrix of small pixels , while other displays have larger elements. LCDs can either be normally on (positive) or off (negative), depending on the polarizer arrangement. For example, a character positive LCD with a backlight has black lettering on a background that is the color of the backlight, and a character negative LCD has a black background with the letters being of the same color as the backlight. LCDs are used in

2398-409: A mini-LED backlight and quantum dot sheets. LCDs with quantum dot enhancement film or quantum dot color filters were introduced from 2015 to 2018. Quantum dots receive blue light from a backlight and convert it to light that allows LCD panels to offer better color reproduction. Quantum dot color filters are manufactured using photoresists containing quantum dots instead of colored pigments, and

2507-455: A number of private equity funds and structured opportunities funds, TowerBrook listed 30 active investments on its website as of 2020. TowerBrook Capital Partners was formed as a spin-off of George Soros' equity management firm . TowerBrook's co-founders, Neal Moszkowski and Ramez Sousou, had previously served as co-heads of Soros Fund Management's private equity arm, Soros Private Equity (SPEP); SPEP launched its first fund around 2000. SPEP

2616-473: A photomask, the unexposed areas are washed away, creating a black grid. Then the same process is repeated with the remaining resists. This fills the holes in the black grid with their corresponding colored resists. Black matrices made in the 1980s and 1990s when most color LCD production was for laptop computers, are made of Chromium due to its high opacity, but due to environmental concerns, manufacturers shifted to black colored photoresist with carbon pigment as

2725-449: A plane parallel to the glass substrates. In this method, the electrical field is applied through opposite electrodes on the same glass substrate, so that the liquid crystals can be reoriented (switched) essentially in the same plane, although fringe fields inhibit a homogeneous reorientation. This requires two transistors for each pixel instead of the single transistor needed for a standard thin-film transistor (TFT) display. The IPS technology

2834-464: A reflective display. The common implementations of LCD backlight technology are: Today, most LCD screens are being designed with an LED backlight instead of the traditional CCFL backlight, while that backlight is dynamically controlled with the video information (dynamic backlight control). The combination with the dynamic backlight control, invented by Philips researchers Douglas Stanton, Martinus Stroomer and Adrianus de Vaan, simultaneously increases

2943-548: A share in a professional sports team," according to Sports Business Daily . Also in 2006, TowerBrook raised $ 850 million from the sale of WellCare Health Plans , and a further $ 160 million from the disposal of Tradedoubler . After acquisition of clothing company Odlo in 2006, in 2007 TowerBrook purchased the designer shoe company Jimmy Choo for £180 million. In 2007, it invested in U.S. company Sound Inpatient Physicians. In 2008, TowerBrook raised $ 2.8 billion from investors for its third fund. According to Financial Times ,

3052-526: A sharper threshold of the contrast-vs-voltage characteristic than the original TN LCDs. This is important, because pixels are subjected to partial voltages even while not selected. Crosstalk between activated and non-activated pixels has to be handled properly by keeping the RMS voltage of non-activated pixels below the threshold voltage as discovered by Peter J. Wild in 1972, while activated pixels are subjected to voltages above threshold (the voltages according to

3161-517: A significant amount. Later that month, the fund purchased 67% of French engineering company GSE, which had an estimated value of €230 million. In 2006, TowerBrook purchased 75% of the St. Louis Blues National Hockey League team for $ 150 million, also then purchasing the lease of the Scottrade Center in St. Louis, Missouri . The purchase made TowerBrook "the only private equity firm to own

3270-483: A significant role in this growth, including as a result of their investments in LCD manufacturers via state-owned investment companies. China had previously imported significant amounts of LCDs, and the growth of its LCD industry decreased prices for other consumer products that use LCDs and led to growth in other sectors like mobile phones. LCDs do not produce light on their own, so they require external light to produce

3379-401: A single mother glass size and as a result, different manufacturers would use slightly different glass sizes for the same generation. Some manufacturers have adopted Gen 8.6 mother glass sheets which are only slightly larger than Gen 8.5, allowing for more 50- and 58-inch LCDs to be made per mother glass, specially 58-inch LCDs, in which case 6 can be produced on a Gen 8.6 mother glass vs only 3 on

In April 2016, TowerBrook announced it was partnering with U.S.-based health system Ascension Health Alliance to develop Ascension's healthcare technology business TRIMEDX. By that summer, the firm had raised

3597-401: A total of $ 9.4 billion from investors in four private equity funds and one structured opportunities fund, designed to allow the firm to make minority investments. The firm completed eight investments in 2017, including purchasing 47% of the aerospace company Aernova and acquisition of loyalty services business Rewards Network. TowerBrook retained 50% of J.Jill stock when taking it public on

3706-641: A total of 5760 wires going vertically and 1080 rows of wires going horizontally. For a panel that is 28.8 inches (73 centimeters) wide, that means a wire density of 200 wires per inch along the horizontal edge. The LCD panel is powered by LCD drivers that are carefully matched up with the edge of the LCD panel at the factory level. The drivers may be installed using several methods, the most common of which are COG (Chip-On-Glass) and TAB ( Tape-automated bonding ) These same principles apply also for smartphone screens that are much smaller than TV screens. LCD panels typically use thinly-coated metallic conductive pathways on

3815-531: A video speed-drive scheme that solved the slow response time of STN-LCDs, enabling high-resolution, high-quality, and smooth-moving video images on STN-LCDs. In 1985, Philips inventors Theodorus Welzen and Adrianus de Vaan solved the problem of driving high-resolution STN-LCDs using low-voltage (CMOS-based) drive electronics, allowing the application of high-quality (high resolution and video speed) LCD panels in battery-operated portable products like notebook computers and mobile phones. In 1985, Philips acquired 100% of

3924-416: A visible image. In a transmissive type of LCD, the light source is provided at the back of the glass stack and is called a backlight . Active-matrix LCDs are almost always backlit. Passive LCDs may be backlit but many are reflective as they use a reflective surface or film at the back of the glass stack to utilize ambient light. Transflective LCDs combine the features of a backlit transmissive display and

4033-496: A voltage to a DSM display switches the initially clear transparent liquid crystal layer into a milky turbid state. DSM displays could be operated in transmissive and in reflective mode but they required a considerable current to flow for their operation. George H. Heilmeier was inducted in the National Inventors Hall of Fame and credited with the invention of LCDs. Heilmeier's work is an IEEE Milestone . In

4578-663: Is applied for a long period of time, this ionic material is attracted to the surfaces and degrades the device performance. This is avoided either by applying an alternating current or by reversing the polarity of the electric field as the device is addressed (the response of the liquid crystal layer is identical, regardless of the polarity of the applied field). Displays for a small number of individual digits or fixed symbols (as in digital watches and pocket calculators ) can be implemented with independent electrodes for each segment. In contrast, full alphanumeric or variable graphics displays are usually implemented with pixels arranged as

4687-407: Is applied to a TN liquid crystal cell, polarized light passes through the 90-degrees twisted LC layer. In proportion to the voltage applied, the liquid crystals untwist changing the polarization and blocking the light's path. By properly adjusting the level of the voltage almost any gray level or transmission can be achieved. In-plane switching is an LCD technology that aligns the liquid crystals in

4796-422: Is applied, the orientation of the liquid-crystal molecules is determined by the alignment at the surfaces of electrodes. In a twisted nematic (TN) device, the surface alignment directions at the two electrodes are perpendicular to each other, and so the molecules arrange themselves in a helical structure, or twist. This induces the rotation of the polarization of the incident light, and the device appears gray. If

Years later, Philips successfully produced and marketed complete modules (consisting of the LCD screen, microphone, speakers etc.) in high-volume production for the booming mobile phone industry. The first color LCD televisions were developed as handheld televisions in Japan. In 1980, Hattori Seiko 's R&D group began development on color LCD pocket televisions. In 1982, Seiko Epson released

7194-401: The addressing method of these bistable displays is rather complex, a reason why these displays did not make it to the market. That changed when in the 2010 "zero-power" (bistable) LCDs became available. Potentially, passive-matrix addressing can be used with devices if their write/erase characteristics are suitable, which was the case for ebooks which need to show still pictures only. After a page

7303-407: The applied voltage is large enough, the liquid crystal molecules in the center of the layer are almost completely untwisted and the polarization of the incident light is not rotated as it passes through the liquid crystal layer. This light will then be mainly polarized perpendicular to the second filter, and thus be blocked and the pixel will appear black. By controlling the voltage applied across

In 1972 North American Rockwell Microelectronics Corp introduced the use of DSM LCDs for calculators for marketing by Lloyds Electronics Inc, though these required an internal light source for illumination. Sharp Corporation followed with DSM LCDs for pocket-sized calculators in 1973 and then mass-produced TN LCDs for watches in 1975. Other Japanese companies soon took

8720-413: The first major English language publication Molecular Structure and Properties of Liquid Crystals was published by Dr. George W. Gray . In 1962, Richard Williams of RCA found that liquid crystals had some interesting electro-optic characteristics and he realized an electro-optical effect by generating stripe patterns in a thin layer of liquid crystal material by the application of a voltage. This effect

8829-409: The first polarizer of the LCD (invented by Philips researchers Adrianus de Vaan and Paulus Schaareman), generally achieved using so called DBEF films manufactured and supplied by 3M. Improved versions of the prism sheet have a wavy rather than a prismatic structure, and introduce waves laterally into the structure of the sheet while also varying the height of the waves, directing even more light towards

8938-476: The first time. LCD TVs were projected to account 50% of the 200 million TVs to be shipped globally in 2006, according to Displaybank . In October 2011, Toshiba announced 2560 × 1600 pixels on a 6.1-inch (155 mm) LCD panel, suitable for use in a tablet computer , especially for Chinese character display. The 2010s also saw the wide adoption of TGP (Tracking Gate-line in Pixel), which moves

9265-587: The late 1960s, pioneering work on liquid crystals was undertaken by the UK's Royal Radar Establishment at Malvern , England. The team at RRE supported ongoing work by George William Gray and his team at the University of Hull who ultimately discovered the cyanobiphenyl liquid crystals, which had correct stability and temperature properties for application in LCDs. The idea of a TFT -based liquid-crystal display (LCD)

9374-705: The light of the backlight uniformly, while a mirror is placed behind the light guide plate to direct all light forwards. The prism sheet with its diffuser sheets are placed on top of the light guide plate. The DBEF polarizers consist of a large stack of uniaxial oriented birefringent films that reflect the former absorbed polarization mode of the light. DBEF polarizers using uniaxial oriented polymerized liquid crystals (birefringent polymers or birefringent glue) were invented in 1989 by Philips researchers Dirk Broer, Adrianus de Vaan and Joerg Brambring. The combination of such reflective polarizers, and LED dynamic backlight control make today's LCD televisions far more efficient than

9483-451: The liquid crystal layer in each pixel, light can be allowed to pass through in varying amounts thus constituting different levels of gray. The chemical formula of the liquid crystals used in LCDs may vary. Formulas may be patented. An example is a mixture of 2-(4-alkoxyphenyl)-5-alkylpyrimidine with cyanobiphenyl, patented by Merck and Sharp Corporation . The patent that covered that specific mixture has expired. Most color LCD systems use

9592-468: The market. Bistable LCDs do not require continuous refreshing. Rewriting is only required for picture information changes. In 1984 HA van Sprang and AJSM de Vaan invented an STN type display that could be operated in a bistable mode, enabling extremely high resolution images up to 4000 lines or more using only low voltages. Since a pixel may be either in an on-state or in an off state at the moment new information needs to be written to that particular pixel,

9701-476: The poor-quality DSM types due to improvements of lower operating voltages and lower power consumption. Tetsuro Hama and Izuhiko Nishimura of Seiko received a US patent dated February 1971, for an electronic wristwatch incorporating a TN-LCD. In 1972, the first wristwatch with TN-LCD was launched on the market: The Gruen Teletime which was a four digit display watch. In 1972, the concept of the active-matrix thin-film transistor (TFT) liquid-crystal display panel

9810-561: The prototypes developed by a Westinghouse team in 1972 were patented in 1976 by a team at Sharp consisting of Fumiaki Funada, Masataka Matsuura, and Tomio Wada, then improved in 1977 by a Sharp team consisting of Kohei Kishi, Hirosaku Nonomura, Keiichiro Shimizu, and Tomio Wada. However, these TFT-LCDs were not yet ready for use in products, as problems with the materials for the TFTs were not yet solved. In 1983, researchers at Brown, Boveri & Cie (BBC) Research Center, Switzerland , invented

9919-456: The quantum dots can have a special structure to improve their application onto the color filter. Quantum dot color filters offer superior light transmission over quantum dot enhancement films.

Chinese firms that developed into world industry leaders included BOE Technology , TCL-CSOT, TIANMA, and Visionox. Local governments had

10028-535: The response time is reduced to just 5 milliseconds when compared with normal STN LCD panels which have a response time of 16 milliseconds. FSC LCDs contain a Chip-On-Glass driver IC can also be used with a capacitive touchscreen. This technique can also be applied in displays meant to show images, as it can offer higher light transmission and thus potential for reduced power consumption in the backlight due to omission of color filters in LCDs. Samsung introduced UFB (Ultra Fine & Bright) displays back in 2002, utilized

10137-508: The same technique, with color filters used to generate red, green, and blue subpixels. The LCD color filters are made with a photolithography process on large glass sheets that are later glued with other glass sheets containing a thin-film transistor (TFT) array, spacers and liquid crystal, creating several color LCDs that are then cut from one another and laminated with polarizer sheets. Red, green, blue and black colored photoresists (resists) are used to create color filters. All resists contain

10246-413: The screen and reducing aliasing or moiré between the structure of the prism sheet and the subpixels of the LCD. A wavy structure is easier to mass-produce than a prismatic one using conventional diamond machine tools, which are used to make the rollers used to imprint the wavy structure into plastic sheets, thus producing prism sheets. A diffuser sheet is placed on both sides of the prism sheet to distribute

In 1936, the Marconi Wireless Telegraph company patented the first practical application of the technology, "The Liquid Crystal Light Valve" . In 1962,

10573-515: The successful fundraising during a difficult economic period was noted as reflecting TowerBrook's sharp decline in its investing pace during a credit boom, while keeping debt for new investments "below the market average." The fund's first deal was in 2009, when TowerBrook acquired 60% of Autodistribution Group for $ 139 million, selling the stake six years later to Bain Capital . In 2009, TowerBrook founded Haymarket Financial, or HayFin, initially as

10682-524: The super-birefringent effect. It has the luminance, color gamut, and most of the contrast of a TFT-LCD, but only consumes as much power as an STN display, according to Samsung. It was being used in a variety of Samsung cellular-telephone models produced until late 2006, when Samsung stopped producing UFB displays. UFB displays were also used in certain models of LG mobile phones. Twisted nematic displays contain liquid crystals that twist and untwist at varying degrees to allow light to pass through. When no voltage

Several Rave theaters (including theaters in Peoria, Illinois and Huntsville, Alabama ) already have Christie systems installed;

11009-625: The various matrix addressing schemes see passive-matrix and active-matrix addressed LCDs . LCDs are manufactured in cleanrooms borrowing techniques from semiconductor manufacturing and using large sheets of glass whose size has increased over time. Several displays are manufactured at the same time, and then cut from the sheet of glass, also known as the mother glass or LCD glass substrate. The increase in size allows more displays or larger displays to be made, just like with increasing wafer sizes in semiconductor manufacturing. The glass sizes are as follows: Until Gen 8, manufacturers would not agree on

11118-499: The viewing angle dependence further by optimizing the shape of the electrodes ( Super IPS ). NEC and Hitachi become early manufacturers of active-matrix addressed LCDs based on the IPS technology. This is a milestone for implementing large-screen LCDs having acceptable visual performance for flat-panel computer monitors and television screens. In 1996, Samsung developed the optical patterning technique that enables multi-domain LCD. Multi-domain and In Plane Switching subsequently remain
