Problems solved by technology

And when the human eye squints at the liquid crystal display at an oblique angle, the relationship between the transmittance and the voltage is represented by a dotted line 102, although the transmittance also changes with the increase of the applied voltage, but in the area 100, the transmittance of the The change did not increase with the applied voltage, but decreased

Embodiment Construction

[0038] Please refer to Figure 3A , is the top view of the liquid crystal display structure of the present invention, wherein the liquid crystal display is composed of data lines D1, D2, D3...Dn and scanning lines G1, G2, G3...Gn, wherein the data lines and scanning lines The area surrounded by adjacent data lines and scan lines perpendicular to each other is called a pixel 303 , and each pixel includes a common electrode Vcom parallel to the scan lines. According to the present invention, a pixel unit 303 is divided into two sub-pixels 3031 and 3032 . Each sub-pixel 3031 or 3032 includes a storage capacitor Cst composed of a pixel electrode and a common electrode, a liquid crystal capacitor Cl??c composed of a pixel electrode and an upper substrate conductive electrode, and a thin film transistor. At the intersection of the data line and the scan line. A data line driving integrated circuit 301 controls the data lines D1, D2, D3...Dn, and a scanning line driving integrated ...

Abstract

The LCD structure comprises at least: multiple parallel data lines, multiple parallel scanning lines crossed with data lines, and multiple switch elements on the crossed points, wherein every pixel area includes two switch elements with one coupled to the data line through another.

Description

technical field [0001] The present invention relates to a pixel unit, in particular to a pixel unit of a liquid crystal display with improved viewing angle. Background technique [0002] Liquid crystal displays have been widely used in various electronic products, such as electronic watches or computers. In order to provide a wide viewing angle, Fujitsu proposed a pixel division vertical alignment (Multi-Domain Vertical Alignment, MVA) technology in 1997. MVA technology can obtain a 160-degree viewing angle, and it can also provide excellent performance with high contrast and fast response. However, the MVA technology has a great disadvantage, that is, when squinting, it will produce a color shift (clor shift) to the skin color of people, especially to the skin color of Asians. [0003] figure 1 A graph showing the relationship between grayscale voltage and transmittance of liquid crystal molecules using MVA technology, wherein the horizontal axis represents the grayscale...
