The price of LCD display panels for TVs is still falling in November and is on the verge of falling back to the level at which it initially rose two years ago (in June 2020). Liu Yushi, a senior analyst at CINNO Research, told China State Grid reporters that the wave of “falling tide” may last until June this year. For related panel companies, after the performance surge in the past year, they will face pressure in 2022.

LCD display panel prices for TVs will remain at a high level throughout 2021 due to the high base of 13 consecutive months of increase, although the price of LCD display panels peaked in June last year and began to decline rapidly. Thanks to this, under the tight demand related to panel enterprises last year achieved substantial profit growth.

According to China State Grid, the annual revenue growth of major LCD display panel manufacturers in China (Shentianma A, TCL Technology, Peking Oriental A, Caihong Shares, Longteng Optoelectronics, AU, Inolux Optoelectronics, Hanyu Color Crystal) in 2021 is basically above double digits, and the net profit growth is also very obvious. Some small and medium-sized enterprises directly turn losses into profits. Leading enterprises such as BOE and TCL Technology more than doubled their net profit.

“There are two main reasons for the ideal performance of domestic display panel enterprises.” A color TV industry analyst believes that, on the one hand, under the effect of the epidemic, the demand for color TV and other electronic products surges, and the upstream raw materials are in shortage, which leads to the short supply of the panel industry, the price rises, and the corporate profits increase accordingly. In addition, as Samsung and LG, the two-panel giants, gradually withdrew from the LCD panel field, they put most of their energy and funds into the OLED(organic light-emitting diode) display panel industry, resulting in a serious shortage of LCD display panels, which objectively benefited China’s local LCD display panel manufacturers such as BOE and TCL China Star Optoelectronics.

Liu Yushi analyzed to reporters that relevant TV panel enterprises made outstanding achievements in 2021, and panel price rise is a very important contributing factor. In addition, three enterprises, such as BOE(BOE), CSOT(TCL China Star Optoelectronics) and HKC(Huike), accounted for 55% of the total shipments of LCD TV panels in 2021. It will be further raised to 60% in the first quarter of 2022. In other words, “simultaneous release of production capacity, expand market share, rising volume and price” is also one of the main reasons for the growth of these enterprises. However, entering the low demand in 2022, LCD TV panel prices continue to fall, and there is some uncertainty about whether the relevant panel companies can continue to grow.

According to Media data, in February this year, the monthly revenue of global large LCD panels has been a double decline of 6.80% month-on-month and 6.18% year-on-year, reaching $6.089 billion. Among them, TCL China Star and AU large-size LCD panel revenue maintained year-on-year growth, while BOE, Innolux, and LG large-size LCD panel monthly revenue decreased by 16.83%, 14.10%, and 5.51% respectively.

Throughout Q1, according to WitsView data, the average LCD TV panel price has been close to or below the average cost, and cash cost level, among which 32-inch LCD TV panel prices are 4.03% and 5.06% below cash cost, respectively; The prices of 43 and 65 inch LCD TV panels are only 0.46% and 3.42% higher than the cash cost, respectively.

The market decline trend is continuing, the reporter queried Omdia, WitsView, Sigmaintel(group intelligence consulting), Oviriwo, CINNO Research, and other institutions regarding the latest forecast data, the analysis results show that the price of the TV LCD panels is expected to continue to decline in April. According to CINNO Research, for example, prices for 32 -, 43 – and 55-inch LCD TV panels in April are expected to fall $1- $3 per screen from March to $37, $65, and $100, respectively. Prices of 65 – and 75-inch LCD TV panels will drop by $8 per screen to $152 and $242, respectively.

In the first quarter of this year, the retail volume of China’s color TV market was 9.03 million units, down 8.8% year on year. Retail sales totaled 28 billion yuan, down 10.1 percent year on year. Under the situation of volume drop, the industry expects this year color TV manufacturers will also set off a new round of LCD display panel prices war.

The TFT-LCD (Flat Panel) Antitrust Litigationclass-action lawsuit regarding the worldwide conspiracy to coordinate the prices of Thin-Film Transistor-Liquid Crystal Display (TFT-LCD) panels, which are used to make laptop computers, computer monitors and televisions, between 1999 and 2006. In March 2010, Judge Susan Illston certified two nationwide classes of persons and entities that directly and indirectly purchased TFT-LCDs – for panel purchasers and purchasers of TFT-LCD integrated products; the litigation was followed by multiple suits.

TFT-LCDs are used in flat-panel televisions, laptop and computer monitors, mobile phones, personal digital assistants, semiconductors and other devices;

In mid-2006, the U.S. Department of Justice (DOJ) Antitrust Division requested FBI assistance in investigating LCD price-fixing. In December 2006, authorities in Japan, Korea, the European Union and the United States revealed a probe into alleged anti-competitive activity among LCD panel manufacturers.

The companies involved, which later became the Defendants, were Taiwanese companies AU Optronics (AUO), Chi Mei, Chunghwa Picture Tubes (Chunghwa), and HannStar; Korean companies LG Display and Samsung; and Japanese companies Hitachi, Sharp and Toshiba.cartel which took place between January 1, 1999, through December 31, 2006, and which was designed to illegally reduce competition and thus inflate prices for LCD panels. The companies exchanged information on future production planning, capacity use, pricing and other commercial conditions.European Commission concluded that the companies were aware they were violating competition rules, and took steps to conceal the venue and results of the meetings; a document by the conspirators requested everybody involved "to take care of security/confidentiality matters and to limit written communication".

Companies directly affected by the LCD price-fixing conspiracy, as direct victims of the cartel, were some of the largest computer, television and cellular telephone manufacturers in the world. These direct action plaintiffs included AT&T Mobility, Best Buy,Costco Wholesale Corporation, Good Guys, Kmart Corp, Motorola Mobility, Newegg, Sears, and Target Corp.Clayton Act (15 U.S.C. § 26) to prevent Defendants from violating Section 1 of the Sherman Act (15 U.S.C. § 1), as well as (b) 23 separate state-wide classes based on each state"s antitrust/consumer protection class action law.

In November 2008, LG, Chunghwa, Hitachi, Epson, and Chi Mei pleaded guilty to criminal charges of fixing prices of TFT-LCD panels sold in the U.S. and agreed to pay criminal fines (see chart).

The South Korea Fair Trade Commission launched legal proceedings as well. It concluded that the companies involved met more than once a month and more than 200 times from September 2001 to December 2006, and imposed fines on the LCD manufacturers.

Sharp Corp. pleaded guilty to three separate conspiracies to fix the prices of TFT-LCD panels sold to Dell Inc., Apple Computer Inc. and Motorola Inc., and was sentenced to pay a $120 million criminal fine,

Seven executives from Japanese and South Korean LCD companies were indicted in the U.S. Four were charged with participating as co-conspirators in the conspiracy and sentenced to prison terms – including LG"s Vice President of Monitor Sales, Chunghwa"s chairman, its chief executive officer, and its Vice President of LCD Sales – for "participating in meetings, conversations and communications in Taiwan, South Korea and the United States to discuss the prices of TFT-LCD panels; agreeing during these meetings, conversations and communications to charge prices of TFT-LCD panels at certain predetermined levels; issuing price quotations in accordance with the agreements reached; exchanging information on sales of TFT-LCD panels for the purpose of monitoring and enforcing adherence to the agreed-upon prices; and authorizing, ordering and consenting to the participation of subordinate employees in the conspiracy."

On December 8, 2010, the European Commission announced it had fined six of the LCD companies involved in a total of €648 million (Samsung Electronics received full immunity under the commission"s 2002 Leniency Notice) – LG Display, AU Optronics, Chimei, Chunghwa Picture and HannStar Display Corporation.

On July 3, 2012, a U.S. federal jury ruled that the remaining defendant, Toshiba Corporation, which denied any wrongdoing, participated in the conspiracy to fix prices of TFT-LCDs and returned a verdict in favor of the plaintiff class. Following the trial, Toshiba agreed to resolve the case by paying the class $30 million.

Large-area TFT LCD panel shipments decreased by 10% Month on Month (MoM) and 5% Year on Year (YoY) in April, to 74.1million units, representing historically low shipment performance since May 2020. Omdia defines large-area TFT LCD displays as larger than 9 inches.

While TV panel prices have decreased noticeably since 3Q21, TV LCD panel shipments increased to a peak of 23.4 million in December 2021, driven by low prices. But rising inflation, the Ukraine crisis and continued lockdowns in China have slowed demand. As a result, TV panel shipments posted a 9% MoM decline in April, to 21.7million units.

"IT LCD panels could still deliver positive cash flow for panel makers. But with prices dropping dramatically, panel makers will soon start to lose money in their IT panel business," Wu said. "Maybe only then will panel makers reduce their glass input and the overall supply/demand situation will return to balance."

Lieff Cabraser served as Court-appointed Co-Lead Counsel for direct purchasers in litigation against the world’s leading manufacturers of Thin Film Transistor Liquid Crystal Displays.

TFT-LCDs are used in flat-panel televisions as well as computer monitors, laptop computers, mobile phones, personal digital assistants, and other devices. Plaintiffs charged that defendants conspired to raise and fix the prices of TFT-LCD panels and certain products containing those panels for over a decade, resulting in overcharges to purchasers of those panels and products.

In March 2010, the Court certified two nationwide classes of persons and entities that directly purchased TFT-LCDs from January 1, 1999 through December 31, 2006, one class of panel purchasers, and one class of buyers of laptop computers, computer monitors, and televisions that contained TFT-LCDs.

TFT (Thin Film Transistor) LCD (Liquid Crystal Display)technology is currently dominant in the display world right now due to its lightweight, low power consumption, low manufacturing cost, etc. But LCDs do have several generic drawbacks. A narrow viewing angle is one of the main issues compared with other display technologies, such asOLED (Organic Light Emitting Diodes), CRT(Cathode-Ray Tube), Plasma, VFD(Vacuum Fluorescent Display), and most recent SamsungMicroLEDdisplays. They also don’t have a response time issue.

LCD scientists and engineers took more than 30 years of effort to improve the TFT LCD viewing angle which has made TFT screens widely applicable in different applications ranging from automotive, home appliances, medical, military, industrial, consumer, etc. The following is a summary of the different TFT wide viewing angle technologies.

When we talk about TFT LCD, we normally mean TN LCD. Thetwisted nematic effect(TN-LCD) takes advantage of the ability of the nematic substance to rotate the polarization of light beams passing through it. Two polarizing filters, parallel planes of glass with their polarizing lines oriented at right angles with respect to each other, are positioned on either side of the liquid crystal. When light enters the display, it is polarized by the input filter. In the absence of an electric field, all the incoming light is transmitted. This is because the light polarization is rotated 90 degrees by the nematic liquid crystal, and the light, therefore, passes easily through the output filter, which is oriented to match the 90-degree shift. With the application of a voltage, an electric field is produced in the nematic liquid crystal. Under these conditions, the polarization effect is reduced. If the voltage is large enough, the polarization effect disappears altogether, and the light is blocked by the output polarizing filter. Refer to Fig.1

In this case, when the display is observed from a vertical direction to the substrate, the display shows a dark state, because the optical axis of the liquid crystal is perpendicular to the substrate. However, when the display is observed from the tilted direction, the display does not show completely a dark state because light leaks due to the birefringence. The birefringence becomes predominant with an increase in the voltage. At different viewing angles, the birefringence is different and the transmission is different in each direction. This is the reason for the poor viewing angle of TFT LCDs. See Fig.3.

O-Film is an optical film that is applied to the TN TFT LCD and redirects light, providing all round viewing angles to any TN TFT LCD to which it is applied. It is easy to apply and relatively low cost.

The best advantage of O Film is to eliminate grayscale inversion. The drawback is to reduce the contrast and brightness. With the wider adoption of IPS, O Film gradually fell out of favor with the market.

The VA (Vertically Aligned) method combines the vertically aligning film and nematic liquid crystal with negative dielectric anisotropy. Contrary to the conventional TN method, a very high

TFT (Thin-Film Transistor) Displays are active-matrix LCDs with full RGB color screens. These screens feature bright, vivid colors and have the ability to show fast animations, complex graphics and crisp custom fonts. TFTs are perfect displays for providing a rich user interface for all types of products. While typically used in consumer devices like personal DVD players and handheld devices, TFTs are also well suited for industrial application.

TFTs are Active-Matrix LCDs that have tiny switching transistors and capacitors. These tiny transistors control each pixel on the display and require very little energy to actively change the orientation of the liquid crystal in the display. This allows for faster control of each Red, Green and Blue sub-pixel cell thus producing clear fast-moving color graphics.

The transistors in the TFT are arranged in a matrix on the glass substrate. Each pixel on the display remains off until addressed by applying a charge to the transistor. Unlike conventional Passive-Matrix displays, in order to activate a specific pixel, the corresponding row is turned on and a charge is sent down the proper column. This is where only the capacitor at the designated pixel receives a charge and is held until the next refresh cycle. Essentially, each transistor acts as an active switch. By incorporating an active switch, this limits the number of scan lines and eliminates cross-talk issues.

The main problem with TN Film technology is that viewing angles are pretty restrictive, especially vertically, and this is evident by a characteristic severe darkening of the image if you look at the screen from below. Contrast and colour tone shifts can be evident with even a slight movement off-centre, and this is perhaps the main drawback in modern TN Film panels. Some TN Film panels are better than others and there have been improvements over the years to some degree, but they are still far more restrictive with fields of view than other panel technologies.

MVA (Multi-domain Vertical Alignment) displays can offer wide viewing angles, good black depth, fast response times, and good color reproduction and depth. Each pixel within a MVA type TFT consists of three sub-pixels (Red, Green and Blue). Each of these sub-pixels is divided further into two or more sub-pixels, where the liquid crystals are randomly lined up due to the ridged polarized glass. When a charge is applied to the transistor, the crystals twist. With these crystals being randomly placed, it allows the backlight to shine through in all different directions keeping the intended color saturation retained while giving the display a 150deg. viewing angle.

In-Plane Switching (IPS) TFTs were developed to improve on the poor viewing angle and the poor color reproduction of TN TFT panels at that time. The crystal molecules move parallel to the panel plane instead of perpendicular to it. This change reduces the amount of light scattering in the matrix, which gives IPS its characteristic wide viewing angles and good color reproduction. Because of its wide viewing angle and accurate color reproduction (with almost no off-angle color shift), IPS is widely employed in high-end monitors aimed at professional graphic artists.

The name In-Plane Switching comes from the crystals in the cells of the IPS panel lying always in the same plane and being always parallel to the panel’s plane (if we don’t take into account the minor interference from the electrodes). When voltage is applied to a cell, the crystals of that cell all make a 90-degrees turn. By the way, an IPS panel lets the backlight pass through in its active state and shutters it in its passive state (when no voltage is applied), so if a thin-film transistor crashes, the corresponding pixel will always remain black, unlike with TN matrices.

IPS (In-Plane Switching) displays provide consistent, accurate color from all viewing angles without blur or grayscale inversion. IPS displays show clear images with fast response time, and no halo effect is produced when touched. Each pixel within an IPS type TFT consists of three sub-pixels (Red, Green and Blue). Each sub-pixel has a pair of electrodes to control the twisting of the Liquid Crystals. Unlike TN type TFTs where the electrodes are on opposing plates, the electrodes in an IPS TFT are on only one of the glass plates (i.e. in the same plane). When voltage is applied to the electrodes, all the Liquid Crystal molecules align in parallel with that plane and allow light to pass through to the polarizers and RGB color filters. In effect, TN displays force the Liquid Crystal molecules perpendicular to the glass which blocks some light from coming out at wide angles, while IPS displays keep the Liquid Crystal molecules in line to allow light through at all angles.

Low-temperature polycrystalline silicon (LTPS) is polycrystalline silicon that has been synthesized at relatively low temperatures (~650 °C and lower) compared to in traditional methods (above 900 °C). LTPS is important for display industries, since the use of large glass panels prohibits exposure to deformative high temperatures. More specifically, the use of polycrystalline silicon in thin-film transistors (LTPS-TFT) has high potential for large-scale production of electronic devices like flat panel LCD displays or image sensors.

Polycrystalline silicon (p-Si) is a pure and conductive form of the element composed of many crystallites, or grains of highly ordered crystal lattice. In 1984, studies showed that amorphous silicon (a-Si) is an excellent precursor for forming p-Si films with stable structures and low surface roughness. Silicon film is synthesized by low-pressure chemical vapor deposition (LPCVD) to minimize surface roughness. First, amorphous silicon is deposited at 560–640 °C. Then it is thermally annealed (recrystallized) at 950–1000 °C. Starting with the amorphous film, rather than directly depositing crystals, produces a product with a superior structure and a desired smoothness. In 1988, researchers discovered that further lowering temperature during annealing, together with advanced plasma-enhanced chemical vapor deposition (PECVD),could facilitate even higher degrees of conductivity. These techniques have profoundly impacted the microelectronics, photovoltaic, and display enhancement industries.

Transflective LCDs combine elements of both transmissive and reflective characteristics. Ambient light passes through the LCD and hits the semi-reflective layer. Most of the light is then reflected back through the LCD. However some of the light will not be reflected and will be lost. Alternately a backlight can be used to provide the light needed to illuminate the LCD if ambient light is low. Light from the backlight passes through a semi-reflective layer and illuminates the LCD. However as with ambient lighting some of the light does not penetrate the semi-reflective layer and is lost.

Transflective LCDs are used in devices that will operate in a wide variety of lighting conditions (from complete darkness to full sunlight). Under dim lighting conditions transflective LCDs offer visual performance similar to transmissive LCDs, whilst under bright lighting conditions they offer visual performance similar to reflective LCDs. However this performance is a tradeoff because the transflective mode is less efficient due to some light loss.
