The displays’ innovative features, such as touchpad frames and fully automated touch detection systems; RFIDs; Ethernet connectivity; and ability to withstand high temperature changes, shock, motion, dust, scrape, and chemicals, are catapulting the industry forward.

Even though displays are a viable substitute for manual methods and outdated push-button technology, the industry offers a large investment opportunity. To keep up with changing industrial needs, the market is differentiated by continuous technological developments. Low-Temperature Poly-Silicon (LTPS), Liquid Crystal Display (LCD), Thin-Film-Transistor (TFT), Digital Light Processing (DLP), and Color Filter (CF) are some of the most recent industry innovations.

Society and the global economy are suffering greatly as a result of the COVID-19 pandemic. The supply chain is being impacted by the outbreak, whose effects are growing every day. Stock market turbulence, a decline in corporate confidence, a considerable delay in the distribution chain, and a rise in customer apprehension are all being brought on by it. European nations under lockdown have suffered major losses in trade and revenue as a result of the suspension of manufacturing operations in the area. The COVID-19 pandemic has had a substantial impact on manufacturing and production processes, slowing the growth of the industrial display sector in 2020.

The creation of thin, effective, and bright displays is made possible by the thin films of organic light-emitting (OLED) materials that emit light when electricity is applied to them. It is anticipated that OLEDs would replace prevailing technologies in the display ecosystem. As a result, a sizable number of businesses have started to increase their investment in OLED study and innovation. OLED industrial displays are dominating the market because to their cutting-edge features, such as higher contrast, quicker response times, and a broader operating temperature range than LCDs. OLED micro displays are now often used in EVFs and HMDs because they outperform conventional LCD and LCoS micro display technologies.

On the basis of technology, the industrial display market is classified into LCD, LED, OLED and E-paper. The LCD segment acquired the highest revenue share in the Industrial Display Market in 2021. A flat panel display called a liquid crystal display (LCD) makes use of the liquid crystals’ capacity to modulate light. Instead of emitting light directly to create images in color or monochrome, liquid crystals use a backlight or reflector. There are two primary categories of LCDs used in electronic devices like digital clocks and video players and those used in computers.

Based on type, the industrial display market is segmented into Rugged Displays, Open-frame Monitors, Panel-Mount Monitors, Marine Displays and Video Walls. The open-frame monitor segment registered a substantial revenue share in the Industrial Display Market in 2021. Open Frame Monitor (OFM) is primarily housed in a bare-metal container and typically does not have a bezel. Instead, it is normally delivered with a mounting metal flange on the outside. Electronic parts, such as the display controller A/D board, the harnesses, and maybe the internal power supply, are secured to the inside of the metal chassis.

By end-use, the industrial display market is categorized into Manufacturing, Mining & Metals, Chemical, Oil, and Gas, Energy & Power, and Others. The Chemical, Oil, and Gas segment registered a promising revenue share in the Industrial Display Market in 2021. Oil and gas have played an important role in the economic transformation, but the industry is entering a new era. Digital transformation can improve productivity and workplace safety while reducing the industry’s environmental impact. Large industrial displays are especially important in the oil and gas industry, where comprehend rough environmental parameters, extreme temperatures, high levels of pollution, and operation is critical not only for safety but also for improving profitability.

Based on panel size, the industrial display market is fragmented into Up to 14”, 14-21”, 21-40”, and 40” and above. The 21-40" segment witnessed a substantial revenue share in the Industrial Display Market in 2021. It is due to the demand for touch screen computer parts in heavy-duty workplaces expected to drive the 21-40" panel size segment’s growth. The anodized coatings on the monitors and touch screen panels, combined with the stainless-steel chassis, are intended to provide operators with greater durability and operation across a wide temperature range.

By application, the industrial display market is divided into HMI, Remote Monitoring, Interactive Display and Digital Signage. The HMI segment garnered the highest revenue share in the Industrial Display Market in 2021. This is because multinational HMI manufacturers are expanding their presence in emerging markets such as China and India. The particular technology is expected to combine the internet’s reach with the ability to control industrial equipment, infrastructural facilities, and operating procedures in factories directly.

Region-wise, the industrial display market is analyzed across North America, Europe, Asia Pacific and LAMEA. The North America region procured the highest revenue share in the Industrial Display Market in 2021. With high demand coming from monitoring system, HMI, and interactive display applications.

lcd module market outlook factory

Specific to the panel display plate, we still do the analysis from both ends of supply and demand: supply-side: February operating rate is insufficient, especially panel display module segment grain rate is not good, limited capacity to boost the panel display price. Since March, effective progress has been made in the prevention and control of the epidemic in China. Except for some production lines in Wuhan that have been delayed, other domestic panels show that the production lines have returned to normal. In South Korea, Samsung announced recently that it would accelerate its withdrawal from all LCD production lines. This round of output withdrawal exceeded market expectations both in terms of pace and amplitude. We will make a detailed analysis of it in Chapter 2.

Demand-side: We believe that people spend more time at home under the epidemic situation, and TV, as an important facility for family entertainment, has strong demand resilience. In our preliminary report, we have interpreted the pick-up trend of domestic TV market demand in February, which also showed a good performance in March. At present, the online market in China maintains a year-on-year growth of about 30% every week, while the offline market is still weak, but its proportion has been greatly reduced. At present, people are more concerned about the impact of the epidemic overseas. According to the research of Cinda Electronics Industry Chain, in the first week, after Italy was closed down, local TV sales dropped by about 45% from the previous week. In addition, Media Markt, Europe’s largest offline consumer electronics chain, also closed in mid-March, which will affect terminal sales to some extent, and panel display prices will continue to be under pressure in April and May. However, we believe that as the epidemic is brought under control, overseas market demand is expected to return to the pace of China’s recovery.

Looking ahead to Q2, we think prices will remain under pressure in May, but prices are expected to pick up in June as Samsung’s capacity is being taken out and the outbreak is under control overseas. At the same time, from the perspective of channel inventory, the current all-channel inventory, including the inventory of all panel display factories, has fallen to a historical low. The industry as a whole has more flexibility to cope with market uncertainties. At the same time, low inventory is also the next epidemic warming panel show price foreshadowing.

We believe the sector is still at the bottom of the stage as Samsung accelerates its exit from LCD capacity and industry inventories remain low. Therefore, once the overseas epidemic is under control and the domestic demand picks up, the panel shows that prices will rise sharply. In addition, the plate will also benefit from Ultra HD drive in the long term. Panel display plate medium – and long-term growth logic is still clear. Coupled with the optimization of the competitive pattern, industry volatility will be greatly weakened. The current plate PB compared to the historical high has sufficient space, optimistic about the plate leading company’s investment value.

1). share market, in April in addition to Zhiyun shares, Tiantong shares, Yizhi technology fell, the rest of the stock plate rose, precision test electronics, Lebao high-tech and TCL technology rose larger, reaching 22.38%, 11.45%, and 11.35% respectively.

In the overseas market, benefiting from the control of the epidemic in Japan and South Korea, all stocks except UDC rose. Among them, Innolux Optoelectronics, Finetek, AU Optoelectronics rose more than 10%.

On March 31, Samsung Display China officially sent a notice to customers, deciding to terminate the supply of all LCD products by the end of 2020.LGD had earlier announced that it would close its local LCDTV panel display production by the end of this year. In the following, we will analyze the impact of the accelerated introduction of the Korean factory on the supply pattern of the panel display industry from the perspective of the supply side.

The early market on the panel display plate is controversial, mainly worried about the exit of Korean manufacturers, such as LCD display panel price rise, or will slow down the pace of capacity exit as in 17 years. And we believe that this round of LCD panel prices and 2017 prices are essentially different, the LCD production capacity of South Korean manufacturers exit is an established strategy, will not be transferred because of price warming. Investigating the reasons, we believe that there are mainly the following three factors driving:

(1) Under the localization, scale effect, and aggregation effect, the Chinese panel leader has lower cost and stronger profitability than the Japanese and Korean manufacturers. In terms of cost structure, according to IHS data, material cost accounts for 70% of the cost displayed by the LCD panel, while depreciation accounts for 17%, so the material cost has a significant impact on it. At present, the upstream LCD, polarizer, PCB, mold, and key target material line of the mainland panel display manufacturers are fully imported into the domestic, effectively reducing the material cost. In addition, at the beginning of the factory, manufacturers not only consider the upstream glass and polarizer factory but also consider the synergy between the downstream complete machine factory, so as to reduce the labor cost, transportation cost, etc., forming a certain industrial clustering effect. The growing volume of shipments also makes the economies of scale increasingly obvious. In the long run, the profit gap between the South Korean plant and the mainland plant will become even wider.

(3) As the large-size OLED panel display technology has become increasingly mature, Samsung and LGD hope to transfer production to large-size OLED with better profit prospects as soon as possible. Apart from the price factor, the reason why South Korean manufacturers are exiting LCD production is more because the large-size OLED panel display technology is becoming mature, and Samsung and LGD hope to switch to large-size OLED production as soon as possible, which has better profit prospects. At present, there are three major large-scale OLED solutions including WOLED, QD OLED, and printed OLED, while there is only WOLED with a mass production line at present.

According to statistics, shipments of OLED TVs totaled 2.8 million in 2018 and increased to 3.5 million in 2019, up 25 percent year on year. But it accounted for only 1.58% of global shipments. The capacity gap has greatly limited the volume of OLED TV.LG alone consumes about 47% of the world’s OLED TV panel display capacity, thanks to its own capacity. Other manufacturers can only purchase at a high price. According to the industry chain survey, the current price of a 65-inch OLED panel is around $800-900, while the price of the same size LCD panel is currently only $171.There is a significant price difference between the two.

Samsung and LGD began to shut down LCD production lines in Q3 last year, leading to the recovery of the panel display sector. Entering 2020, the two major South Korean plants have announced further capacity withdrawal planning. In the following section, we will focus on its capacity exit plan and compare it with the original plan. It can be seen that the pace and magnitude of Samsung’s exit this round is much higher than the market expectation:

(1) LGD: LGD currently has three large LCD production lines of P7, P8, and P9 in China, with a designed capacity of 230K, 240K, and 90K respectively. At the CES exhibition at the beginning of this year, the company announced that IT would shut down all TV panel display production capacity in South Korea in 2020, mainly P7 and P8 lines, while P9 is not included in the exit plan because IT supplies IT panel display for Apple.

(2) Samsung: At present, Samsung has L8-1, L8-2, and L7-2 large-size LCD production lines in South Korea, with designed production capacities of 200K, 150K, and 160K respectively. At the same time in Suzhou has a 70K capacity of 8 generation line.

This round of capacity withdrawal of South Korean plants began in June 2019. Based on the global total production capacity in June 2019, Samsung will withdraw 1,386,900 square meters of production capacity in 2019-2020, equivalent to 9.69% of the global production capacity, according to the previous two-year withdrawal expectation. In 2021, 697,200 square meters of production capacity will be withdrawn, which is equivalent to 4.87% of the global production capacity, and a total of 14.56% will be withdrawn in three years. After the implementation of the new plan, Samsung will eliminate 2.422 million square meters of production capacity by the end of 2020, equivalent to 16.92 percent of the global capacity. This round of production plans from the pace and range are far beyond the market expectations.

Global shipments of TV panel displays totaled 281 million in 2019, down 1.06 percent year on year, according to Insight. In fact, TV panel display shipments have been stable since 2015 at between 250 and 300 million units. At the same time, from the perspective of the structure of sales volume, the period from 2005 to 2010 was the period when the size of China’s TV market grew substantially. Third-world sales also leveled off in 2014. We believe that the sales volume of the TV market has stabilized and there is no big fluctuation. The impact of the epidemic on the overall demand may be more optimistic than the market expectation.

Meanwhile, the global LCDTV panel display demand will increase significantly in 2021, driven by the recovery of terminal demand and the continued growth of the average TV size. In 2021, the whole year panel display will be in a short supply situation, the mainland panel shows that both males will enjoy the price elasticity.

This paper analyzes the competition pattern of the panel display industry from both supply and demand sides. On the supply side, the optimization of the industry competition pattern by accelerating the withdrawal of Samsung’s production capacity is deeply discussed. Demand-side focuses on tracking global sales data and industry inventory changes. Overall, we believe that the current epidemic has a certain impact on demand, and the panel shows that prices may be under short-term pressure in April or May. But as Samsung’s exit from LCD capacity accelerates, industry inventories remain low. So once the overseas epidemic is contained and domestic demand picks up, the panel suggests prices will surge. We are firmly optimistic about the A-share panel display plate investment value, maintain the industry “optimistic” rating. Suggested attention: BOE A, TCL Technology.

LCDs find application in a wide range of devices such as smartphones, notebooks, televisions, curved TVs, tablets, digital signage and offer various other benefits with regard to performance and lightweight properties. These displays have higher resolution and more portable than traditional televisions and monitors ; they can produce high-quality digital images.

Prior to the Covid-19 pandemic outbreak in early 2020, the flat-panel display (FPD) market was gloomy. Oversupply, falling prices and losses were the common themes in the market.

It’s been a different story during the outbreak. In 2020, the FPD market rebounded. In the stay-at-home economy, consumers went on a buying spree for monitors, PCs, tablets and TVs. As a result, demand for displays exploded. And shortages soon surfaced for display driver ICs and other components.

2021 is expected to be another boom year, but the party may be over in 2022. The global flat panel display market is expected to jump 28% in 2021 to reach a record high of $ 151 billion. A performance drawn more by old LCD screens (liquid crystal display) than Oled screens.

A liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers. Liquid crystals do not emit light directlybacklight or reflector to produce images in color or monochrome.seven-segment displays, as in a digital clock, are all good examples of devices with these displays. They use the same basic technology, except that arbitrary images are made from 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 will have black lettering on a background that is the color of the backlight, and a character negative LCD will have a black background with the letters being of the same color as the backlight. Optical filters are added to white on blue LCDs to give them their characteristic appearance.

LCDs are used in a wide range of applications, including LCD televisions, computer monitors, instrument panels, aircraft cockpit displays, and indoor and outdoor signage. Small LCD screens are common in LCD projectors and portable consumer devices such as digital cameras, watches, digital clocks, calculators, and mobile telephones, including smartphones. LCD screens are also used on consumer electronics products such as DVD players, video game devices and clocks. LCD screens have replaced heavy, bulky cathode-ray tube (CRT) displays in nearly all applications. LCD screens are available in a wider range of screen sizes than CRT and plasma displays, with LCD screens available in sizes ranging from tiny digital watches to very large television receivers. LCDs are slowly being replaced by OLEDs, which can be easily made into different shapes, and have a lower response time, wider color gamut, virtually infinite color contrast and viewing angles, lower weight for a given display size and a slimmer profile (because OLEDs use a single glass or plastic panel whereas LCDs use two glass panels; the thickness of the panels increases with size but the increase is more noticeable on LCDs) and potentially lower power consumption (as the display is only "on" where needed and there is no backlight). OLEDs, however, are more expensive for a given display size due to the very expensive electroluminescent materials or phosphors that they use. Also due to the use of phosphors, OLEDs suffer from screen burn-in and there is currently no way to recycle OLED displays, whereas LCD panels can be recycled, although the technology required to recycle LCDs is not yet widespread. Attempts to maintain the competitiveness of LCDs are quantum dot displays, marketed as SUHD, QLED or Triluminos, which are displays with blue LED backlighting and a Quantum-dot enhancement film (QDEF) that converts part of the blue light into red and green, offering similar performance to an OLED display at a lower price, but the quantum dot layer that gives these displays their characteristics can not yet be recycled.

Since LCD screens do not use phosphors, they rarely suffer image burn-in when a static image is displayed on a screen for a long time, e.g., the table frame for an airline flight schedule on an indoor sign. LCDs are, however, susceptible to image persistence.battery-powered electronic equipment more efficiently than a CRT can be. By 2008, annual sales of televisions with LCD screens exceeded sales of CRT units worldwide, and the CRT became obsolete for most purposes.

Each pixel of an LCD typically consists of 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 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 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 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.Sharp Corporation. The patent that covered that specific mixture expired.

Most color LCD systems use 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 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 photoresists (resists) are used. All resists contain 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.Super-twisted nematic LCD, where the variable twist between tighter-spaced plates causes a varying double refraction birefringence, thus changing the hue.

The optical effect of 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 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 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.alphanumeric or variable graphics displays are usually implemented with pixels arranged as 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 the various matrix addressing schemes see passive-matrix and active-matrix addressed LCDs.

LCDs, along with OLED displays, 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 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 a Gen 8.5 mother glass, significantly reducing waste.AGC Inc., Corning Inc., and Nippon Electric Glass.

In 1922, Georges Friedel described the structure and properties of liquid crystals and classified them in three types (nematics, smectics and cholesterics). In 1927, Vsevolod Frederiks devised the electrically switched light valve, called the Fréedericksz transition, the essential effect of all LCD technology. In 1936, the Marconi Wireless Telegraph company patented the first practical application of the technology, "The Liquid Crystal Light Valve". In 1962, the first major English language publication Molecular Structure and Properties of Liquid Crystals was published by Dr. George W. Gray.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 is based on an electro-hydrodynamic instability forming what are now called "Williams domains" inside the liquid crystal.

In 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) was conceived by Bernard Lechner of RCA Laboratories in 1968.dynamic scattering mode (DSM) LCD that used standard discrete MOSFETs.

On December 4, 1970, the twisted nematic field effect (TN) in liquid crystals was filed for patent by Hoffmann-LaRoche in Switzerland, (Swiss patent No. 532 261) with Wolfgang Helfrich and Martin Schadt (then working for the Central Research Laboratories) listed as inventors.Brown, Boveri & Cie, its joint venture partner at that time, which produced TN displays for wristwatches and other applications during the 1970s for the international markets including the Japanese electronics industry, which soon produced the first digital quartz wristwatches with TN-LCDs and numerous other products. James Fergason, while working with Sardari Arora and Alfred Saupe at Kent State University Liquid Crystal Institute, filed an identical patent in the United States on April 22, 1971.ILIXCO (now LXD Incorporated), produced LCDs based on the TN-effect, which soon superseded 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 concept of the active-matrix thin-film transistor (TFT) liquid-crystal display panel was prototyped in the United States by T. Peter Brody"s team at Westinghouse, in Pittsburgh, Pennsylvania.Westinghouse Research Laboratories demonstrated the first thin-film-transistor liquid-crystal display (TFT LCD).high-resolution and high-quality electronic visual display devices use TFT-based active matrix displays.active-matrix liquid-crystal display (AM LCD) in 1974, and then Brody coined the term "active matrix" in 1975.

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 1973Seiko 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.TFT LCDs similar to 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,

In 1983, researchers at Brown, Boveri & Cie (BBC) Research Center, Switzerland, invented the passive matrix-addressed LCDs. H. Amstutz et al. were listed as inventors in the corresponding patent applications filed in Switzerland on July 7, 1983, and October 28, 1983. Patents were granted in Switzerland CH 665491, Europe EP 0131216,

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.Seiko Epson released the first LCD television, the Epson TV Watch, a wristwatch equipped with a small active-matrix LCD television.dot matrix TN-LCD in 1983.Citizen Watch,TFT LCD.computer monitors and LCD televisions.3LCD projection technology in the 1980s, and licensed it for use in projectors in 1988.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 was to use interdigital electrodes on one glass substrate only to produce an electric field essentially parallel to the glass substrates.Germany by Guenter Baur et al. and patented in various countries.Hitachi work out various practical details of the IPS technology to interconnect the thin-film transistor array as a matrix and to avoid undesirable stray fields in between pixels.

Hitachi also improved 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 the dominant LCD designs through 2006.South Korea and Taiwan,

In 2007 the image quality of LCD televisions surpassed the image quality of cathode-ray-tube-based (CRT) TVs.LCD TVs were projected to account 50% of the 200 million TVs to be shipped globally in 2006, according to Displaybank.Toshiba announced 2560 × 1600 pixels on a 6.1-inch (155 mm) LCD panel, suitable for use in a tablet computer,transparent and flexible, but they cannot emit light without a backlight like OLED and microLED, which are other technologies that can also be made flexible and transparent.

In 2016, Panasonic developed IPS LCDs with a contrast ratio of 1,000,000:1, rivaling OLEDs. This technology was later put into mass production as dual layer, dual panel or LMCL (Light Modulating Cell Layer) LCDs. The technology uses 2 liquid crystal layers instead of one, and may be used along with a mini-LED backlight and quantum dot sheets.

Since LCDs produce no light of their own, they require external light to produce a visible image.backlight. Active-matrix LCDs are almost always backlit.Transflective LCDs combine the features of a backlit transmissive display and a reflective display.

CCFL: The LCD panel is lit either by two cold cathode fluorescent lamps placed at opposite edges of the display or an array of parallel CCFLs behind larger displays. A diffuser (made of PMMA acrylic plastic, also known as a wave or light guide/guiding plateinverter to convert whatever DC voltage the device uses (usually 5 or 12 V) to ≈1000 V needed to light a CCFL.

EL-WLED: The LCD panel is lit by a row of white LEDs placed at one or more edges of the screen. A light diffuser (light guide plate, LGP) is then used to spread the light evenly across the whole display, similarly to edge-lit CCFL LCD backlights. The diffuser is made out of either PMMA plastic or special glass, PMMA is used in most cases because it is rugged, while special glass is used when the thickness of the LCD is of primary concern, because it doesn"t expand as much when heated or exposed to moisture, which allows LCDs to be just 5mm thick. Quantum dots may be placed on top of the diffuser as a quantum dot enhancement film (QDEF, in which case they need a layer to be protected from heat and humidity) or on the color filter of the LCD, replacing the resists that are normally used.

WLED array: The LCD panel is lit by a full array of white LEDs placed behind a diffuser behind the panel. LCDs that use this implementation will usually have the ability to dim or completely turn off the LEDs in the dark areas of the image being displayed, effectively increasing the contrast ratio of the display. The precision with which this can be done will depend on the number of dimming zones of the display. The more dimming zones, the more precise the dimming, with less obvious blooming artifacts which are visible as dark grey patches surrounded by the unlit areas of the LCD. As of 2012, this design gets most of its use from upscale, larger-screen LCD televisions.

RGB-LED array: Similar to the WLED array, except the panel is lit by a full array of RGB LEDs. While displays lit with white LEDs usually have a poorer color gamut than CCFL lit displays, panels lit with RGB LEDs have very wide color gamuts. This implementation is most popular on professional graphics editing LCDs. As of 2012, LCDs in this category usually cost more than $1000. As of 2016 the cost of this category has drastically reduced and such LCD televisions obtained same price levels as the former 28" (71 cm) CRT based categories.

Monochrome LEDs: such as red, green, yellow or blue LEDs are used in the small passive monochrome LCDs typically used in clocks, watches and small appliances.

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 the dynamic range of the display system (also marketed as HDR, high dynamic range television or FLAD, full-area local area dimming).

The LCD backlight systems are made highly efficient by applying optical films such as prismatic structure (prism sheet) to gain the light into the desired viewer directions and reflective polarizing films that recycle the polarized light that was formerly absorbed by the first polarizer of the LCD (invented by Philips researchers Adrianus de Vaan and Paulus Schaareman),

Due to the LCD layer that generates the desired high resolution images at flashing video speeds using very low power electronics in combination with LED based backlight technologies, LCD technology has become the dominant display technology for products such as televisions, desktop monitors, notebooks, tablets, smartphones and mobile phones. Although competing OLED technology is pushed to the market, such OLED displays do not feature the HDR capabilities like LCDs in combination with 2D LED backlight technologies have, reason why the annual market of such LCD-based products is still growing faster (in volume) than OLED-based products while the efficiency of LCDs (and products like portable computers, mobile phones and televisions) may even be further improved by preventing the light to be absorbed in the colour filters of the LCD.

A standard television receiver screen, a modern LCD panel, has over six million pixels, and they are all individually powered by a wire network embedded in the screen. The fine wires, or pathways, form 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 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.anisotropic conductive film or, for lower densities, elastomeric connectors.

Monochrome and later color passive-matrix LCDs were standard in most early laptops (although a few used plasma displaysGame Boyactive-matrix became standard on all laptops. 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 is needed.

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 response times and poor contrast are typical of passive-matrix addressed LCDs with too many pixels and driven according to the "Alt & Pleshko" drive scheme. Welzen and de Vaan also invented a non RMS drive scheme enabling to drive STN displays with video rates and enabling to show smooth moving video images on an STN display.

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.

High-resolution color displays, such as modern LCD computer monitors and televisions, use an active-matrix structure. A matrix of thin-film transistors (TFTs) is added to the electrodes in contact with the LC layer. Each pixel has its own dedicated transistor, allowing each column line to access one pixel. When a row line is selected, all of the column lines are connected to a row of pixels and voltages corresponding to the picture information are driven onto all of the column lines. The row line is then deactivated and the next row line is selected. All of the row lines are selected in sequence during 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 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 the backlight becomes red, and it turns OFF when the backlight becomes green. To make a segment appear black, the segment is always turned ON. An FSC LCD divides a color image into 3 images (one Red, one Green and one Blue) and it displays them in order. Due to persistence of vision, the 3 monochromatic images appear as one color image. An FSC LCD needs an LCD panel with a refresh rate of 180 Hz, and the response time is reduced to just 5 milliseconds when compared with normal STN LCD panels which have a response time of 16 milliseconds.

Samsung introduced UFB (Ultra Fine & Bright) displays back in 2002, utilized 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.

In-plane switching is an LCD technology that aligns the liquid crystals in 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 is used in everything from televisions, computer monitors, and even wearable devices, especially almost all LCD smartphone panels are IPS/FFS mode. IPS displays belong to the LCD panel family screen types. The other two types are VA and TN. Before LG Enhanced IPS was introduced in 2001 by Hitachi as 17" monitor in Market, the additional transistors resulted in blocking more transmission area, thus requiring a brighter backlight and consuming more power, making this type of display less desirable for notebook computers. Panasonic Himeji G8.5 was using an enhanced version of IPS, also LGD in Korea, then currently the world biggest LCD panel manufacture BOE in China is also IPS/FFS mode TV panel.

Most of the new M+ technology was employed on 4K TV sets which led to a controversy after tests showed that the addition of a white sub pixel replacing the traditional RGB structure would reduce the resolution by around 25%. This means that a 4K TV cannot display the full UHD TV standard. The media and internet users later called this "RGBW" TVs because of the white sub pixel. Although LG Display has developed this technology for use in notebook display, outdoor and smartphones, it became more popular in the TV market because the announced 4K UHD resolution but still being incapable of achieving true UHD resolution defined by the CTA as 3840x2160 active pixels with 8-bit color. This negatively impacts the rendering of text, making it a bit fuzzier, which is especially noticeable when a TV is used as a PC monitor.

In 2011, LG claimed the smartphone LG Optimus Black (IPS LCD (LCD NOVA)) has the brightness up to 700 nits, while the competitor has only IPS LCD with 518 nits and double an active-matrix OLED (AMOLED) display with 305 nits. LG also claimed the NOVA display to be 50 percent more efficient than regular LCDs and to consume only 50 percent of the power of AMOLED displays when producing white on screen.

This pixel-layout is found in S-IPS LCDs. A chevron shape is used to widen the viewing cone (range of viewing directions with good contrast and low color shift).

Vertical-alignment displays are a form of LCDs in which the liquid crystals naturally align vertically to the glass substrates. When no voltage is applied, the liquid crystals remain perpendicular to the substrate, creating a black display between crossed polarizers. When voltage is applied, the liquid crystals shift to a tilted position, allowing light to pass through and create a gray-scale display depending on the amount of tilt generated by the electric field. It has a deeper-black background, a higher contrast ratio, a wider viewing angle, and better image quality at extreme temperatures than traditional twisted-nematic displays.

Blue phase mode LCDs have been shown as engineering samples early in 2008, but they are not in mass-production. The physics of blue phase mode LCDs suggest that very short switching times (≈1 ms) can be achieved, so time sequential color control can possibly be realized and expensive color filters would be obsolete.

Some LCD panels have defective transistors, causing permanently lit or unlit pixels which are commonly referred to as stuck pixels or dead pixels respectively. Unlike integrated circuits (ICs), LCD panels with a few defective transistors are usually still usable. Manufacturers" policies for the acceptable number of defective pixels vary greatly. At one point, Samsung held a zero-tolerance policy for LCD monitors sold in Korea.ISO 13406-2 standard.

Dead pixel policies are often hotly debated between manufacturers and customers. To regulate the acceptability of defects and to protect the end user, ISO released the ISO 13406-2 standard,ISO 9241, specifically ISO-9241-302, 303, 305, 307:2008 pixel defects. However, not every LCD manufacturer conforms to the ISO standard and the ISO standard is quite often interpreted in different ways. LCD panels are more likely to have defects than most ICs due to their larger size. For example, a 300 mm SVGA LCD has 8 defects and a 150 mm wafer has only 3 defects. However, 134 of the 137 dies on the wafer will be acceptable, whereas rejection of the whole LCD panel would be a 0% yield. In recent years, quality control has been improved. An SVGA LCD panel with 4 defective pixels is usually considered defective and customers can request an exchange for a new one.

Some manufacturers, notably in South Korea where some of the largest LCD panel manufacturers, such as LG, are located, now have a zero-defective-pixel guarantee, which is an extra screening process which can then determine "A"- and "B"-grade panels.clouding (or less commonly mura), which describes the uneven patches of changes in luminance. It is most visible in dark or black areas of displayed scenes.

The zenithal bistable device (ZBD), developed by Qinetiq (formerly DERA), can retain an image without power. The crystals may exist in one of two stable orientations ("black" and "white") and power is only required to change the image. ZBD Displays is a spin-off company from QinetiQ who manufactured both grayscale and color ZBD devices. Kent Displays has also developed a "no-power" display that uses polymer stabilized cholesteric liquid crystal (ChLCD). In 2009 Kent demonstrated the use of a ChLCD to cover the entire surface of a mobile phone, allowing it to change colors, and keep that
