The most common semiconducting layer is made of amorphous silicon (a-Si). a-Si  thin film transistor - liquid crystal display (TFT-LCD) has been the dominant technology for the manufacturing of active matrix TFT-LCD for over 20 years. a-Si is a low cost material in abundant supply.

a-Si is a low cost material in abundant supply. However, the electron mobility of a-Si is very low (around 1cm2/Vs) and can’t physically support high refresh rates such as the 240Hz needed for HDTV. Due to their high electron mobility, new materials such as metal oxide (MO) and low temperature polysilicon (LTPS) are now replacing a-Si to manufacture the industry’s two main types of screens: LCD and organic light-emitting diode (OLED) displays.

Flat-panel displays are thin panels of glass or plastic used for electronically displaying text, images, or video. Liquid crystal displays (LCD), OLED (organic light emitting diode) and microLED displays are not quite the same; since LCD uses a liquid crystal that reacts to an electric current blocking light or allowing it to pass through the panel, whereas OLED/microLED displays consist of electroluminescent organic/inorganic materials that generate light when a current is passed through the material. LCD, OLED and microLED displays are driven using LTPS, IGZO, LTPO, and A-Si TFT transistor technologies as their backplane using ITO to supply current to the transistors and in turn to the liquid crystal or electroluminescent material. Segment and passive OLED and LCD displays do not use a backplane but use indium tin oxide (ITO), a transparent conductive material, to pass current to the electroluminescent material or liquid crystal. In LCDs, there is an even layer of liquid crystal throughout the panel whereas an OLED display has the electroluminescent material only where it is meant to light up. OLEDs, LCDs and microLEDs can be made flexible and transparent, but LCDs require a backlight because they cannot emit light on their own like OLEDs and microLEDs.

Liquid-crystal display (or LCD) is a thin, flat panel used for electronically displaying information such as text, images, and moving pictures. They are usually made of glass but they can also be made out of plastic. Some manufacturers make transparent LCD panels and special sequential color segment LCDs that have higher than usual refresh rates and an RGB backlight. The backlight is synchronized with the display so that the colors will show up as needed. The list of LCD manufacturers:

Organic light emitting diode (or OLED displays) is a thin, flat panel made of glass or plastic used for electronically displaying information such as text, images, and moving pictures. OLED panels can also take the shape of a light panel, where red, green and blue light emitting materials are stacked to create a white light panel. OLED displays can also be made transparent and/or flexible and these transparent panels are available on the market and are widely used in smartphones with under-display optical fingerprint sensors. LCD and OLED displays are available in different shapes, the most prominent of which is a circular display, which is used in smartwatches. The list of OLED display manufacturers:

MicroLED displays is an emerging flat-panel display technology consisting of arrays of microscopic LEDs forming the individual pixel elements. Like OLED, microLED offers infinite contrast ratio, but unlike OLED, microLED is immune to screen burn-in, and consumes less power while having higher light output, as it uses LEDs instead of organic electroluminescent materials, The list of MicroLED display manufacturers:

Sony produces and sells commercial MicroLED displays called CLEDIS (Crystal-LED Integrated Displays, also called Canvas-LED) in small quantities.video walls.

LCDs are made in a glass substrate. For OLED, the substrate can also be plastic. The size of the substrates are specified in generations, with each generation using a larger substrate. For example, a 4th generation substrate is larger in size than a 3rd generation substrate. A larger substrate allows for more panels to be cut from a single substrate, or for larger panels to be made, akin to increasing wafer sizes in the semiconductor industry.

Samsung Display, one of the leading amorphous silicon (a-Si) TFT LCD manufacturers for the past 20 years, is shutting down its first G7 line, Line 7-1, from as early as the end of July and there are rumors of a few more fab closures to come. Its a-Si TFT LCD footprint is expected to shrink dramatically over the next few years with potentially just one a-Si fab in operation in 2018 to serve its market-leading TV business.

Panasonic LCD is also rumored to be shutting down most or all of its G8.5 line. Based on the near term decline in a-Si TFT LCD capacity, Credit Suisse upgraded AUO and Innolux on this news and their shares surged.

Samsung’s Line 7-1, which began operation in October 2004 and production in May 2005, is rumored to be shutting down from the 30th July through the end of the year. It has a unique glass size (1,870 x 2,200mm), which was the largest in the world at the time of its introduction and is optimized for both 40” and 46” LCD TV panel production. It was also the site of the Samsung-Sony joint venture, S-LCD, established in April 2004. This line enabled Samsung and Sony to rapidly take share from smaller G6 fabs optimized for 32” and 37” panels. During that time, the two companies competed aggressively in retail while establishing 40” and 46” as mainstream sizes. The JV with Sony ended in 2011. S-LCD also built an 8th gen fab that began production in Q3’07, and Samsung built a second G7 line (L7-2) on its own, with even more capacity at over 170,000 substrates per month. L7-2 began production in Q3’08.

Displays are already a weak spot in Samsung’s financial performance. The category caused the device solutions division to be the only one to suffer a loss among all major divisions within Samsung in Q1’16, and its revenues of KRW6 trillion ($5.2 billion) were the lowest in two years. The display division alone posted an operating loss of KRW270 billion ($233 million) in Q1’16 resulting in an operating margin of -4.4%. While Samsung has a number of technology and capacity advantages in OLEDs for mobile displays, its a-Si TFT LCD business has matured and is increasingly becoming commoditized, as new entrants from China with government support are taking share. In addition, most of the a-Si TFT LCD market segments have become stagnant or are in decline, which points to more losses given the growing Chinese competition. On the other hand, OLEDs and flexible OLEDs are poised for rapid growth as they take share. As a result, it makes good business sense for Samsung to exit much of the a-Si TFT LCD market.

Line 7-2, newer and larger than 7-1, is also rumored to be for sale and is expected to be shut down in 2017, but probably depends on profitability. Line 7-2 has been producing 3-4 million 40” panels and 300,000 75” panels annually, as well as monitor panels. Twinstar is also a potential customer for the manufacturing equipment and this line may also be utilized for OLED production in the future.

Samsung is expected to begin shipping for the first OLED iPhone in volume from Q3’17, with input capacity from the modified Line 7 ramping up to between 90,000 and 120,000 substrates per month. Apple is expected to purchase 70 million OLED panels in 2017, according to sources.

That is not all, however. Line 6, Samsung"s last 5th gen line with 1,100 x 1,300mm substrates and around 190,000 substrate per month capacity, is also expected to be shut down, according to industry insiders. That line, which features a-Si and oxide TFT LCD production, has been producing tablet, notebook PC and LCD monitor panels. Those markets have also been hit by stagnant demand, growing competition from China, commoditization and declining margins. This line is expected to be shut down between the end of 2016 and 2017. Line 6 is predicted to be converted to a semiconductor facility, making application processors for smartphones and tablets.

If Samsung closes down Line 6 and Lines 7-1 and 7-2, its a-Si production will be down to just two G8.5 fabs: one in Suzhou, China and one in Tangjong, Korea. The Suzhou fab, ramping to over 100,000 substrates per month, is also rumored to be a candidate for sale with Chinese and Indian TFT LCD suppliers as potential customers. If Samsung licenses its latest a-Si TFT LCD or oxide TFT LCD technology, that would certainly make the sale more attractive. This means Samsung would have just one a-Si TFT LCD fab: Line 8.

I believe Line 8 will be sufficient for Samsung to support its internal TV brand with leading edge panels for the TV market as it has a monthly capacity of 400,000 2,200 x 2,500mm (G8.5) substrates. Samsung’s TV business would likely continue to outsource its low-end panels for its TVs to other LCD manufacturers and focus this fab on higher margin products such as 8k, HDR, QD WCG, etc. I cannot see Samsung abandoning LCD TV panel production until it believes OLEDs are cost effective enough to takeover the mid-range high end of the TV market. This likely means not until OLED materials can be inkjet printed, Samsung is still likely to focus all of its TV panel production on LCDs.

If this occurs as described, Samsung Display"s output of 42" and larger panels would be LCD, and sub-42" would be OLED, although it may not have much production between 15" and 40". This would be an amazing, but expected, transformation given the supply/demand and profitability outlook for the a-Si market.

Panasonic is also following Samsung’s lead. It is expected to reduce the glass input of its G8.5 line from around 50,000 per month to just 10,000 per month by September. Given the limited scale and cost effectiveness of this Japanese factory and the loss of share of Panasonic"s TV brand in many regional TV markets, the company is better off purchasing panels from LG and lower cost Chinese suppliers. Otherwise it would be trying to run a high cost fab in Japan, in a market where commoditization is becoming increasingly common and a large wave of new, lower cost capacity from China is on its way. The company may keep 10,000 of capacity for some period for Panasonic-branded products, but it is hard to imagine operating a fab at just 10,000 per month for long, as the lack of volume will further increase costs relative to other higher volume players.

Interestingly, with both Samsung and Panasonic reducing their a-Si capacity in the near term, Credit Suisse has upgraded its outlook for AUO and Innolux to outperform, and both companies have seen significant share price increases as a result. Credit Suisse indicated that the closure of L7-1 will reduce supply by 12 million 40” panels - or 1/3 of the 40” market - which will tighten supply in the 40”-43” market and produce a better pricing environment. AUO’s earnings per share (EPS) was raised from NT$10.20 to NT$13 ($0.32 - $0.40), while Innolux’s EPS was raised from NT$10.10 to NT$14 ($0.31 - $0.43). Both companies" stock prices have taken off, with AUO’s stock price rising by 22% in the US in three days.

As Japanese and Korean players take more a-Si capacity offline, it will create a better environment for the Taiwanese and Chinese suppliers, enabling the market to better digest all the new capacity being brought online in China. However, there is a tremendous amount of capacity coming and much of this older capacity from Samsung and Panasonic may get sold and reintroduced. As pointed out at SID 2016, by 2019 China is expected to have:

2016 and 2017 are expected to be back-to-back years of over $12 billion in LCD/OLED equipment spending. Unless these fabs struggle with their ramp and their yields, the a-Si market will continue to be oversupplied although conditions should improve in the 40”-43” market in the second half of 2016.

Rather than battle it out with government-subsidized Chinese players, Samsung appears to be accelerating its exit of the increasingly commoditized a-Si TFT LCD market. This should please its shareholders, especially if it can sell all its old equipment and license its a-Si technology for a royalty, but will be harmful to some of its suppliers. It is also likely to protect its TV business by holding onto its most competitive fab, but will increasingly become an OLED company. Interesting questions as a result of these moves include:

Will LG Display follow Samsung’s lead and accelerate the closure of its older a-Si lines, or will it slug it out against the new wave of Chinese capacity?

A couple of days after this article was originally posted, it was claimed - and later denied by a company official - that Samsung will move its a-Si TFT LCD operations out of Samsung Display and into Samsung Electronics. Such a move aligns perfectly with its intention, indicated above, to close its a-Si fabs as in a couple of years its a-Si TFT LCD operations may be limited to providing panels to its TV business. - Ross Young

IPS (In-Plane Switching) lcd is still a type of TFT LCD, IPS TFT is also called SFT LCD (supper fine tft ),different to regular tft in TN (Twisted Nematic) mode, theIPS LCD liquid crystal elements inside the tft lcd cell, they are arrayed in plane inside the lcd cell when power off, so the light can not transmit it via theIPS lcdwhen power off, When power on, the liquid crystal elements inside the IPS tft would switch in a small angle, then the light would go through the IPS lcd display, then the display on since light go through the IPS display, the switching angle is related to the input power, the switch angle is related to the input power value of IPS LCD, the more switch angle, the more light would transmit the IPS LCD, we call it negative display mode.

The regular tft lcd, it is a-si TN (Twisted Nematic) tft lcd, its liquid crystal elements are arrayed in vertical type, the light could transmit the regularTFT LCDwhen power off. When power on, the liquid crystal twist in some angle, then it block the light transmit the tft lcd, then make the display elements display on by this way, the liquid crystal twist angle is also related to the input power, the more twist angle, the more light would be blocked by the tft lcd, it is tft lcd working mode.

A TFT lcd display is vivid and colorful than a common monochrome lcd display. TFT refreshes more quickly response than a monochrome LCD display and shows motion more smoothly. TFT displays use more electricity in driving than monochrome LCD screens, so they not only cost more in the first place, but they are also more expensive to drive tft lcd screen.The two most common types of TFT LCDs are IPS and TN displays.
