Multi-domain liquid crystal display (LCD)

Abstract

The invention provides a multi-domain liquid crystal display (LCD). The display includes an LCD panel, an incident-side polarizer and an exit-side polarizer. The LCD panel includes a plurality of pixel structures arranged in an array. Each pixel structure includes at least two sub-pixels respectively corresponding to different colors. Each sub-pixel is divided into at least four domain regions. Each domain region includes a plurality of branch electrodes which are mutually parallel and are distributed in a spaced manner. Included angles between branch electrodes of at least two sub-pixels respectively corresponding to different colors to the sub-pixels of different colors and a transmission axis of the incident-side polarizer are different. Compared with the prior art, the display furtherenables the branch electrodes in the sub-pixels corresponding to the different colors and the transmission axis of the incident-side polarizer to have the different angles on the basis of a multi-domain structure to reduce degree difference of voltage transmission rate curve deviation of red, green and blue sub-pixels under squinting and emmetropia, can effectively relieve the visual-angle color deviation problem of liquid crystal display panels, is simple in a structure and a manufacturing method, and cannot bring other additional manufacturing process and cost impacts.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a multi-domain liquid crystal display. Background technique [0002] Liquid Crystal Display (LCD) has many advantages such as thin body, power saving, and no radiation, and has been widely used, such as: LCD TV, mobile phone, personal digital assistant (PDA), digital camera, computer screen or Laptop screens, etc., dominate the field of flat panel displays. [0003] Active Thin Film Transistor-LCD (Thin Film Transistor-LCD, TFT-LCD) is currently the most common liquid crystal display in the mainstream market. According to different liquid crystal driving methods, it can be roughly divided into: twisted nematic (Twisted Nematic, TN) or Super Twisted Nematic (STN) type, In-Plane Switching (IPS) type, and Vertical Alignment (VA) type. Compared with other types of liquid crystal displays, the VA type liquid crystal display has a very high contrast ratio, and has a very wide applic...

Problems solved by technology

[0006] Technologies based on the above principles are often achieved through capacitive coupling or multi-TFT control. Among them, the method based on capacitive coupling has been widely used, but there are also some problems, such as: 1. The degree of capacitive coupling varies in different manufacturing processes There are differences, and affected by the difficulty of adjusting the thickness of the conductive layer and the dimensional accuracy in the manufacturing process, it is difficult to control; 2. Under different voltages, the sub pixel area voltage (Vsub) generated by coupling is not necessarily linear, and at the same time different Vsub in grayscale is affected by the semiconductor and its process characteristics. Even if the same design is used, the improvement effect will be different under different equipment and processes; LCD aperture ratio, thereby reducing the transmittance of the display
