Structure of liquid crystal display

Abstract

A liquid crystal display is prepared for using multiple data line and scan line to define out pixel unit, forming each pixel unit by the first pixel and the second pixel, coupling the first shared electrode with at least one of multiple voltage source, electric-coupling the second shared electrode with two of multiple voltage source through the first and the second switching-over elements, and controlling the first and the second switching-over elements separately by their adjacent scan lines.

Description

technical field [0001] The present invention relates to a liquid crystal display, in particular to a pixel structure of a liquid crystal display. Background technique [0002] Liquid crystal displays have been widely used in various electronic products, such as electronic watches or calculators. In order to provide a wide viewing angle, Fujitsu (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 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 cause a color shift (color shift) phenomenon to the skin color of people, especially the skin color of Asians. [0003] FIG. 1 shows a graph showing the relationship between grayscale voltage and transmittance of liquid crystal molecules using MVA technology, wherein the horizontal axis represents the g...

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 as the applied voltage increases, but in the area 100, the change of the transmittance It does not increase with the increase of the applied voltage, but decreases, which is the main cause of color shift
