(11 September 2017) – The large thin film transistor (TFT) display market is expected to continue to expand in 2017 despite slower end-market demand, according to IHS Markit (Nasdaq: INFO), a world leader in critical information, analytics and solutions.

Among displays of 9 inches or larger, tablet PC displays are on track to record the highest year-on-year growth in unit shipments in 2017, with 10 percent growth to 93 million units. “It is because first-tier set brands are increasing the number of tablet PC models with larger screens. The new 10.5-inch iPad pro is a good example,” said

The second fastest-growing application is notebook PC displays, with a 4 percent year-on-year growth to about 175 million units. “Chinese panel makers are aggressively trying to expand in this market, while first-tier panel makers are actually retreating panel production,” Su said.

On the flip side, TV displays are showing a contraction in 2017 by 3 percent year on year, dropping to 257 million units due to slower end-market demand. “Prices of large displays, particularly TV panels, have stayed high for almost a year. TV brands started revising down their business plan, cutting their panel purchases,” Su said.

In terms of area shipments, however, large displays for all applications are forecast to see growth in 2017 as larger screens become more popular with consumers. TV display accounts for 78 percent of total large display shipments by area, and is expected to see a 5 percent growth in 2017.

“First-tier panel makers, especially South Korean companies, already started shifting their production to larger sizes -- 49 inches or larger -- while reducing production of smaller panels, with lower profitability, to achieve better financial performance,” Su said. “Chinese panel makers are following suit and started increasing production of larger TV displays to 43-inch or larger.”

LG Display is expected to continue accounting for the largest market share in 2017 with 21 percent as measured by unit shipments. BOE, a Chinese display maker that has been increasing its shipments significantly, is forecast to take 20.7 percent, up 2 percentage points from 2016, gaining on LG Display.

IHS Markit provides information about the entire range of large display panels shipped worldwide and regionally, including monthly and quarterly revenues and shipments by display area, application, size and aspect ratio for each supplier.

A thin-film-transistor liquid-crystal display (TFT LCD) is a variant of a liquid-crystal display that uses thin-film-transistor technologyactive matrix LCD, in contrast to passive matrix LCDs or simple, direct-driven (i.e. with segments directly connected to electronics outside the LCD) LCDs with a few segments.

In February 1957, John Wallmark of RCA filed a patent for a thin film MOSFET. Paul K. Weimer, also of RCA implemented Wallmark"s ideas and developed the thin-film transistor (TFT) in 1962, a type of MOSFET distinct from the standard bulk MOSFET. It was made with thin films of cadmium selenide and cadmium sulfide. The idea of a TFT-based liquid-crystal display (LCD) was conceived by Bernard Lechner of RCA Laboratories in 1968. In 1971, Lechner, F. J. Marlowe, E. O. Nester and J. Tults demonstrated a 2-by-18 matrix display driven by a hybrid circuit using the dynamic scattering mode of LCDs.T. Peter Brody, J. A. Asars and G. D. Dixon at Westinghouse Research Laboratories developed a CdSe (cadmium selenide) TFT, which they used to demonstrate the first CdSe thin-film-transistor liquid-crystal display (TFT LCD).active-matrix liquid-crystal display (AM LCD) using CdSe TFTs in 1974, and then Brody coined the term "active matrix" in 1975.high-resolution and high-quality electronic visual display devices use TFT-based active matrix displays.

The liquid crystal displays used in calculators and other devices with similarly simple displays have direct-driven image elements, and therefore a voltage can be easily applied across just one segment of these types of displays without interfering with the other segments. This would be impractical for a large display, because it would have a large number of (color) picture elements (pixels), and thus it would require millions of connections, both top and bottom for each one of the three colors (red, green and blue) of every pixel. To avoid this issue, the pixels are addressed in rows and columns, reducing the connection count from millions down to thousands. The column and row wires attach to transistor switches, one for each pixel. The one-way current passing characteristic of the transistor prevents the charge that is being applied to each pixel from being drained between refreshes to a display"s image. Each pixel is a small capacitor with a layer of insulating liquid crystal sandwiched between transparent conductive ITO layers.

The circuit layout process of a TFT-LCD is very similar to that of semiconductor products. However, rather than fabricating the transistors from silicon, that is formed into a crystalline silicon wafer, they are made from a thin film of amorphous silicon that is deposited on a glass panel. The silicon layer for TFT-LCDs is typically deposited using the PECVD process.

Polycrystalline silicon is sometimes used in displays requiring higher TFT performance. Examples include small high-resolution displays such as those found in projectors or viewfinders. Amorphous silicon-based TFTs are by far the most common, due to their lower production cost, whereas polycrystalline silicon TFTs are more costly and much more difficult to produce.

The twisted nematic display is one of the oldest and frequently cheapest kind of LCD display technologies available. TN displays benefit from fast pixel response times and less smearing than other LCD display technology, but suffer from poor color reproduction and limited viewing angles, especially in the vertical direction. Colors will shift, potentially to the point of completely inverting, when viewed at an angle that is not perpendicular to the display. Modern, high end consumer products have developed methods to overcome the technology"s shortcomings, such as RTC (Response Time Compensation / Overdrive) technologies. Modern TN displays can look significantly better than older TN displays from decades earlier, but overall TN has inferior viewing angles and poor color in comparison to other technology.

Most TN panels can represent colors using only six bits per RGB channel, or 18 bit in total, and are unable to display the 16.7 million color shades (24-bit truecolor) that are available using 24-bit color. Instead, these panels display interpolated 24-bit color using a dithering method that combines adjacent pixels to simulate the desired shade. They can also use a form of temporal dithering called Frame Rate Control (FRC), which cycles between different shades with each new frame to simulate an intermediate shade. Such 18 bit panels with dithering are sometimes advertised as having "16.2 million colors". These color simulation methods are noticeable to many people and highly bothersome to some.gamut (often referred to as a percentage of the NTSC 1953 color gamut) are also due to backlighting technology. It is not uncommon for older displays to range from 10% to 26% of the NTSC color gamut, whereas other kind of displays, utilizing more complicated CCFL or LED phosphor formulations or RGB LED backlights, may extend past 100% of the NTSC color gamut, a difference quite perceivable by the human eye.

In 2004, Hydis Technologies Co., Ltd licensed its AFFS patent to Japan"s Hitachi Displays. Hitachi is using AFFS to manufacture high end panels in their product line. In 2006, Hydis also licensed its AFFS to Sanyo Epson Imaging Devices Corporation.

A technology developed by Samsung is Super PLS, which bears similarities to IPS panels, has wider viewing angles, better image quality, increased brightness, and lower production costs. PLS technology debuted in the PC display market with the release of the Samsung S27A850 and S24A850 monitors in September 2011.

TFT dual-transistor pixel or cell technology is a reflective-display technology for use in very-low-power-consumption applications such as electronic shelf labels (ESL), digital watches, or metering. DTP involves adding a secondary transistor gate in the single TFT cell to maintain the display of a pixel during a period of 1s without loss of image or without degrading the TFT transistors over time. By slowing the refresh rate of the standard frequency from 60 Hz to 1 Hz, DTP claims to increase the power efficiency by multiple orders of magnitude.

Due to the very high cost of building TFT factories, there are few major OEM panel vendors for large display panels. The glass panel suppliers are as follows:

External consumer display devices like a TFT LCD feature one or more analog VGA, DVI, HDMI, or DisplayPort interface, with many featuring a selection of these interfaces. Inside external display devices there is a controller board that will convert the video signal using color mapping and image scaling usually employing the discrete cosine transform (DCT) in order to convert any video source like CVBS, VGA, DVI, HDMI, etc. into digital RGB at the native resolution of the display panel. In a laptop the graphics chip will directly produce a signal suitable for connection to the built-in TFT display. A control mechanism for the backlight is usually included on the same controller board.

The low level interface of STN, DSTN, or TFT display panels use either single ended TTL 5 V signal for older displays or TTL 3.3 V for slightly newer displays that transmits the pixel clock, horizontal sync, vertical sync, digital red, digital green, digital blue in parallel. Some models (for example the AT070TN92) also feature input/display enable, horizontal scan direction and vertical scan direction signals.

New and large (>15") TFT displays often use LVDS signaling that transmits the same contents as the parallel interface (Hsync, Vsync, RGB) but will put control and RGB bits into a number of serial transmission lines synchronized to a clock whose rate is equal to the pixel rate. LVDS transmits seven bits per clock per data line, with six bits being data and one bit used to signal if the other six bits need to be inverted in order to maintain DC balance. Low-cost TFT displays often have three data lines and therefore only directly support 18 bits per pixel. Upscale displays have four or five data lines to support 24 bits per pixel (truecolor) or 30 bits per pixel respectively. Panel manufacturers are slowly replacing LVDS with Internal DisplayPort and Embedded DisplayPort, which allow sixfold reduction of the number of differential pairs.

The bare display panel will only accept a digital video signal at the resolution determined by the panel pixel matrix designed at manufacture. Some screen panels will ignore the LSB bits of the color information to present a consistent interface (8 bit -> 6 bit/color x3).

With analogue signals like VGA, the display controller also needs to perform a high speed analog to digital conversion. With digital input signals like DVI or HDMI some simple reordering of the bits is needed before feeding it to the rescaler if the input resolution doesn"t match the display panel resolution.

At present, TFT LCD touch panel prices rebounded, after six months of continuous decline, TFT LCD touch panel prices began to rebound at the end of July. Global TFT LCD panel prices have rebounded since August, according to Displaysearch, an international market-research firm. The price of a 17-inch LCD touch panel rose 6.6% to $112 in August, up from $105 in July, and fell from $140 in March to $105 in July. At the same time, 15 – inch, 19 – inch LCD touch panel prices also showed a different range of recovery. The price of a 17-inch LCD touch panel rose 5.8 percent, to $110, from $104 in late July, according to early August quotes from consulting firm with a view. Analysts believe the rebound will continue through the third quarter; LCDS will see seasonal growth in the third quarter, driven by back-to-school sales in us and the completion of inventory liquidation in the first half of the year. Dell and Hewlett-Packard (HPQ) started placing orders for monitors in the third quarter, and display makers Samsungelectronics (SXG) and TPV (TPV) are expected to increase production by 25% and 18% respectively.

It seems that due to the increasing demand in the market, the production capacity of the display panel production line has been released. Domestic TFT-LCD touch panel makers boe and Shanghai guardian said their production schedules have been set for September, and their production capacity may reach full capacity by the end of the year. Jd will produce 85,000 glass substrates per month (with a designed capacity of 90,000), according to boe and Shanghai guardian. Previously, panel makers have been hit by falling prices, with boe, SFT, and even international panel giant LG Philips all reporting losses. If the rebound continues into the fourth quarter, boe, Shanghai radio and television and other panel makers will use the rebound to reverse the decline, according to industry analysts.

It is understood that the first quarter of the boe financial results show that the company’s main business income of 2.44 billion yuan, a loss of 490 million yuan.Jd.com attributed the loss to a drop in the price of 17-inch TFT-LCD displays made by its Beijing TFT-LCD fifth-generation production line of Beijing boe photoelectric technology co., LTD., a subsidiary. Boe has issued the announcement of pre-loss in the first half of the year in April. Due to the influence of the off-season of TFT-LCD business operation in the first quarter of 2006, the company has suffered a large operating loss, and the low price in the TFT-LCD market has continued till now. Therefore, it is expected that the operating loss will still occur in the first half of 2006.LG Philips, the world’s largest TFT LCD maker, reported a won322bn ($340m) loss in July, compared with a won41.1bn profit a year earlier.LG Philips attributed the loss to fierce price competition and market demand did not meet expectations.

Such 18 bit panels with dithering are sometimes advertised as having "16.2 million colors". These color simulation methods are noticeable to many people and highly bothersome to some.gamut (often referred to as a percentage of the NTSC 1953 color gamut) are also due to backlighting technology. It is not uncommon for older displays to range from 10% to 26% of the NTSC color gamut, whereas other kind of displays, utilizing more complicated CCFL or LED phosphor formulations or RGB LED backlights, may extend past 100% of the NTSC color gamut, a difference quite perceivable by the human eye.

Initial iterations of IPS technology were characterised by slow response time and a low contrast ratio but later revisions have made marked improvements to these shortcomings. 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, although with the recent fall in price it has been seen in the mainstream market as well. IPS technology was sold to Panasonic by Hitachi.

In 2004, Hydis Technologies Co., Ltd licensed its AFFS patent to Japan"s Hitachi Displays. Hitachi is using AFFS to manufacture high end panels in their product line. In 2006, Hydis also licensed its AFFS to Sanyo Epson Imaging Devices Corporation.

A technology developed by Samsung is Super PLS, which bears similarities to IPS panels, has wider viewing angles, better image quality, increased brightness, and lower production costs. PLS technology debuted in the PC display market with the release of the Samsung S27A850 and S24A850 monitors in September 2011.

TFT dual-transistor pixel or cell technology is a reflective-display technology for use in very-low-power-consumption applications such as electronic shelf labels (ESL), digital watches, or metering. DTP involves adding a secondary transistor gate in the single TFT cell to maintain the display of a pixel during a period of 1s without loss of image or without degrading the TFT transistors over time. By slowing the refresh rate of the standard frequency from 60 Hz to 1 Hz, DTP claims to increase the power efficiency by multiple orders of magnitude.

Due to the very high cost of building TFT factories, there are few major OEM panel vendors for large display panels. The glass panel suppliers are as follows:

External consumer display devices like a TFT LCD feature one or more analog VGA, DVI, HDMI, or DisplayPort interface, with many featuring a selection of these interfaces. Inside external display devices there is a controller board that will convert the video signal using color mapping and image scaling usually employing the discrete cosine transform (DCT) in order to convert any video source like CVBS, VGA, DVI, HDMI, etc. into digital RGB at the native resolution of the display panel. In a laptop the graphics chip will directly produce a signal suitable for connection to the built-in TFT display. A control mechanism for the backlight is usually included on the same controller board.

The low level interface of STN, DSTN, or TFT display panels use either single ended TTL 5 V signal for older displays or TTL 3.3 V for slightly newer displays that transmits the pixel clock, horizontal sync, vertical sync, digital red, digital green, digital blue in parallel. Some models (for example the AT070TN92) also feature input/display enable, horizontal scan direction and vertical scan direction signals.

New and large (>15") TFT displays often use LVDS signaling that transmits the same contents as the parallel interface (Hsync, Vsync, RGB) but will put control and RGB bits into a number of serial transmission lines synchronized to a clock whose rate is equal to the pixel rate. LVDS transmits seven bits per clock per data line, with six bits being data and one bit used to signal if the other six bits need to be inverted in order to maintain DC balance. Low-cost TFT displays often have three data lines and therefore only directly support 18 bits per pixel. Upscale displays have four or five data lines to support 24 bits per pixel (truecolor) or 30 bits per pixel respectively. Panel manufacturers are slowly replacing LVDS with Internal DisplayPort and Embedded DisplayPort, which allow sixfold reduction of the number of differential pairs.

The bare display panel will only accept a digital video signal at the resolution determined by the panel pixel matrix designed at manufacture. Some screen panels will ignore the LSB bits of the color information to present a consistent interface (8 bit -> 6 bit/color x3).

With analogue signals like VGA, the display controller also needs to perform a high speed analog to digital conversion. With digital input signals like DVI or HDMI some simple reordering of the bits is needed before feeding it to the rescaler if the input resolution doesn"t match the display panel resolution.

The statements are applicable to Merck KGaA as well as its competitors JNC Corporation (formerly Chisso Corporation) and DIC (formerly Dainippon Ink & Chemicals). All three manufacturers have agreed not to introduce any acutely toxic or mutagenic liquid crystals to the market. They cover more than 90 percent of the global liquid crystal market. The remaining market share of liquid crystals, produced primarily in China, consists of older, patent-free substances from the three leading world producers and have already been tested for toxicity by them. As a result, they can also be considered non-toxic.

Korean makers of thin film transistor liquid crystal display (TFT-LCD) panels are taking advantage of a continuing gap between supply and demand to push up prices while raising sales targets. The LG conglomerate’s LG-LCD unit has released figures showing sales of its panels in the first half of its fiscal year reached $780m, up 424% year-on-year. Press reports quoted company sources as saying they expect to make a net profit of $129m on that revenue. The company has readjusted its sales target for the year from $1bn to $1.7bn. Samsung Electronics Co, the market leader in the international 13.3-inch TFT-LCD market, has not yet released its first-half figures but analysts say following $400m sales in the first quarter, they expect sales for the half of well over $800m. Samsung’s last projection for the year raised the forecast from $1.1bn to $1.6bn.

Samsung says that demand for TFT-LCD displays for notebook PCs is rapidly changing from 12.1-inch panels to 13.3-inch products, while at the same time demand for 15.1-inch LCDs used for desktop monitors is increasing significantly. The price of 13.3-inch LCDs has risen 40% from earlier this year to about $500 per panel while 15.1-inch panels cost around $600, Samsung said. The market shortage will continue for the rest of this year, pushing prices up further, analysts say, but additional capacity in Korea and Japan and several new facilities in Taiwan will ease the supply shortage early next year. á

WASHINGTON – A former executive from HannStar Display Corporation has agreed to plead guilty and to serve jail time in the United States for participating in a global conspiracy to fix the price of thin-film transistor liquid crystal display (TFT-LCD) panels, the Department of Justice announced today.

According to a one-count felony charge filed today in U.S. District Court in San Francisco, Jui Hung "Sam" Wu conspired with others to suppress and eliminate competition by fixing the prices of TFT-LCD panels. Wu, a resident of Taiwan and the former executive director of global sales and marketing of HannStar, a Taiwan-based corporation, participated in the conspiracy from as early as Sept. 21, 2001, until on or about Jan. 31, 2006.

Under his plea agreement, which is subject to court approval, Wu has agreed to serve seven months in jail, to pay a $20,000 criminal fine and to assist the department in its ongoing TFT-LCD investigation.

TFT-LCD panels are used in computer monitors and notebooks, televisions, mobile phones and other electronic devices. By the end of the conspiracy period, the worldwide market for TFT-LCD panels was valued at $70 billion. Companies directly affected by the LCD price-fixing conspiracy are some of the largest computer and television manufacturers in the world, including Apple, Dell and Hewlett Packard.

The department charged that Wu participated in a conspiracy in which the participants met and agreed to charge prices of TFT-LCD panels at certain predetermined levels. The participants in that conspiracy also issued price quotations in accordance with the agreements reached and exchanged information on the sales of TFT-LCD panels for the purpose of monitoring adherence to the agreed-upon prices, the department said.

Anyone with information concerning illegal conduct in the TFT-LCD industry is urged to call the Antitrust Division’s San Francisco Field Office at 415-436-6660 or visit www.justice.gov/atr/contact/newcase.htm.
