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.

It also engages in property holding; investment securities holding; and marketing and sales consulting activities. The company was formerly known as Varitronix International Limited and changed its name to BOE Varitronix Limited in July 2017. BOE Varitronix Limited was founded in 1978 and is headquartered in Kwun Tong, Hong Kong.

BOE Varitronix Limited and the Subcontractors entered into the Master Subcontracting Agreement, pursuant to which the Company has agreed to provide subcontracting services of manufacturing TFT/TP modules and other products on a non-exclusive basis to the Subcontractors, for a term from 29 April 2022 to 31 December 2024. For the avoidance of doubt, the Group is not contractually bound to provide the subcontracting services to the

Master Subcontracting Agreement. TFT modules are thin film transistor modules which generally refer to a unit comprises, among others, a panel, backlight and integrated circuits. TP modules are modules with touch panel displays. The other products are vehicle networking and automotive electronic systems which include, among others, electronic communications devices within a vehicle such as remote control of the headlights/air-conditioner using a smartphone app or a remote control, navigation system, electronic monitoring system, global positioning system module, radio and head-up display.

Shares in the manufacturer of LCD displays for automobiles and other products had not been traded since that day because the company requested a stock trade suspension, citing an upcoming announcement of a significant business development. The announcement finally came Tuesday night, revealing a deal in which BOE Technology Group will purchase 400 million new shares in Varitronix at HK$3.50 per share.
