Thin-Film Transistor Liquid Crystal Displays use thin-film transistors to control the voltage applied to the liquid crystal layer at a sub-pixel level. The structure of TFT LCDs consists of a TFT “sandwich” and a BLU (Backlight Unit). A typical configuration is shown in the schematic diagram below.

Firstly, between the back and front polarizers, TFT LCD cells are made with two glass substrates – one for color filters, the other for a TFT array – and a liquid crystal layer sandwiched in between.

For normally black TFT LCDs, if we follow along a piece of light setting off from its backlight source, it will bea)guided uniformly by LGP;b)reflected and enhanced by BEF and DBEF;c)polarized by the back polarizer;d)polarization changed by twisted LC under the voltage applied by TFT arrays;e)“tinted” red/green/blue by corresponding color filter of the subpixel;f)let through the front polarizer by matched polarization; andg)finally, it will reach the surface and appears in viewer’s eyes.

For normally white panels, processd)will be the opposite – known as the polarization rotation effect, light is twisted in a voltage-off stage and can pass through the front polarizer by default, thus displaying white normally. However, when the voltage applied increases, this polarization rotation effect would be gradually diminished. And the light would not be able to pass through the front polarizer anymore without changing its polarization. In this way, certain pixels will appear in different colors.

Normally black LCDs have higher contrast and wider viewing angles without grayscale inversion phenomenon compared to their normally white relatives. And whether TFT LCDs are normally black or white depends on their LC switching mode:

As previously mentioned, TN mode functions with the polarization rotation effect. Under traditional TN/VA display mode, the liquid crystal molecules are vertically arranged, with a relatively narrow visual angle. When an external force is exerted on the screen, the liquid crystal molecular structure will sink in a herringbone pattern to slowly recover – a pattern called vertical alignment. Therefore, an evident “water ripple” usually appears when the display surface is touched and impacts the user experience. In comparison, the VA mode provides higher contrast. And MVA (multi-domain vertical alignment) is an upgraded version of VA with improved viewing angles.

BOE Varitronix, formerly a of a Hong Kong company focusing on R&D and manufacturing of automotive display and industrial display, has been established for more than 40 years. In 2016, BOE became the major shareholder of Varitronix.

BOE Technology Group Co., Ltd., or Jingdongfang (Chinese: 京东方科技集团股份有限公司), is a Chinese electronic components producer founded in April 1993. Its core businesses are interface devices, smart IoT systems and smart medicine and engineering integration.LCD, OLEDs and flexible displays.

In April 1993, Beijing Oriental Electronics Group Co., Ltd was founded by Wang Dongsheng. In 1997, it listed B shares on the Shenzhen Stock Exchange. In 2001, Beijing Oriental Electronics was renamed BOE Technology Group Co., Ltd. BOE acquired SK Hynix"s STN-LCD and OLED businesses for US$22.5 million.flat-panel display businesses for US$380 million.

In 2009, BOE Energy Technology Co., Ltd was founded to enter the photovoltaics industry. In 2010, BOE acquired Suzhou Gaochuang Electronics" Taipei Display Research Center and AIO Manufacturing Plant.

In 2017, BOE established its Middle East Branch in Dubai and set up a subsidiary based in São Paulo, Brazil. BOE also announced its plan to build a hospital in Chengdu which will be opened in late 2020. BOE announced a long-term agreement with Universal Display Corporation, UDC will supply phosphorescent OLED materials to BOE.LG Display still lead in terms of area shipment.

In 2018, BOE acquired SES-imagotag for €200 million.Kopin Corporation and Olightek for OLED micro-displays manufacturing.Huawei Mate 20 Pro is the first flagship tier smartphone with an AMOLED sourced from BOE (also sourced from LG Display).

In 2019, BOE formed a joint venture with Rohinni for MicroLED and mini LED backlighting manufacturing.Hisense announced its U9E TVs featuring dual LCD panels which Hisense said exceeds OLED TVs in brightness, color gamut and color accuracy. Its panels are produced by BOE.Huawei Mate X scheduled for release in Q4 2019 reportly has a foldable OLED from BOE.Samsung Displays.flat-panel display producer.Huawei to research cameras under OLEDs.LG Display and Tianma as OLED supplier for LG Electronics smartphones in 2020.Apple beginning in 2021 for the iPhone.

The small & medium-sized display devices refer to the ones sized below 11 inches. Along with the massive operation of high-generation TFT-LCD production lines, the original manufacturers specialized in large-sized G3-G5.5 lines have been markedly inferior to those of G6-G10 TFT-LCD production lines; in consequence, they have successively transferred into the fabrication of small & medium-sized display devices, which initiated the oversupply, particularly in the medium-sized field (5-11 inches) whose price plunged.

Firstly, mobile phone display features even larger sizes as the smart phone flourishes. The display size of mainstream smart phone reaches 3.5 inches, and that of the high-end one rests on 4.3 inches which is the double of that of common mobile phone. The resolution also becomes higher, with the mainstream one of 800*480 or 800*854, and the high-end one of 960*640, a quadruple of the common mobile phone.

The ASP of mobile phone display has been on the rise from the ever falling status. It turned out to be US$8.06 in 2010, up 11.8% against 2009, and promisingly, it will maintain the growth momentum by 2013.

Secondly, the medium-sized display market thrives. As the netbook was massively rolled out into the market in 2009, the small & medium-sized display industry still achieved growth against the economic crisis. And in 2010, the large shipment of tablet PC fueled the growth of medium-sized display market.

The small & medium-sized display industry experienced sharp fluctuations in 2010. CPT and HANNSTAR were completely transformed into the manufacturers of small & medium-sized display devices. The shipment of CPT in 2010 was as high as 352 million, up 135% from 2009; and that of HANNSTAR registered 248 million, up 505% against 2009. However, subject to the not high average unit price and the low gross profit despite the booming shipment, as well as the high depreciation of TFT-LCD production line, both of the manufacturers were suffering from loss.

SMD has been engaged in OLED for years, and it ultimately made significant breakthrough in 2010. By virtue of the fully depreciated G4.5 LTPS TFT-LCD production line, the OLED shipment of SMD greatly expanded. Samsung, Nokia, HTC, and Lenovo massively employed OLED as mobile phone display. In 2010, the output value of OLED industry rose 92% from 2009, of which SMD contributed more than 95%. In 2011, SMD will excel Sharp by means of OLED and blossom into the world’s largest manufacturer of small & medium-sized display.

In H2 2010, due to the deficient capacity of LG Display, Apple iPhone increased its display suppliers Sharp and TMD. Sharp originally provided display devices for Apple except iPhone and iPad. Benefiting from the long-term orders and the fabulous cash support of Apple, Sharp reopened the three production lines (closed at the end of 2008 because of the economic downturn) of small & medium-sized display devices of TENRI and MIE.

In late 2010, Hon Hai intended to purchase 50% equities of Hitachi Display for JPY100 billion, but the negotiation failed. In early 2011, Sony Mobile Display sold its subsidiary-STMD to Kyocera; meanwhile, Sony acquired the G4 line of EID, and purchased the back-end module fab of Epson in Suzhou for RMB780 million.

Epson, the global largest manufacturer of small & medium-sized display in 2004 and 2005, has witnessed the declined performance during the recent years, and it is probable to retreat from the field ultimately.

Promoted by the display giants headed by Samsung and LG, OLED industry is still in the stage of steady development. In 2011, the OLED output value worldwide approximated USD3.3 billion, with year-on-y...
