Problems solved by technology

[0003] However, in the color films of general displays, the thickness of the blue film is the largest, followed by the thickness of the green film, and then the thickness of the red film, and the gap between the liquid crystal cells is defined / monitored / measured by the thickness of the green film, so There is a difference between the defined / monitored / measured liquid crystal layer gap and the actual liquid crystal layer gap, which will affect the Δnd and affect the transmittance value of the liquid crystal layer, and finally cause the voltage of red (R) / green (G) / blue (B) to pass through. The transmittance curve (V-T) is different (see figure 1 , where Tr-R is the voltage red light transmittance curve, Tr-G is the voltage green light transmittance curve, and Tr-B is the voltage blue light transmittance curve. It can be seen from the curves that under the same gray scale voltage, Red light transmittance > green light transmittance > blue light transmittance), which makes the white points of each gray scale inconsistent

Abstract

A pixel electrode unit, comprising: a first pixel electrode unit for allowing red, green, and blue lights to pass through, a second pixel electrode unit, and a third pixel electrode unit. The electrode width of a main electrode of the first pixel electrode unit is W R. The electrode width of a main electrode of the second pixel electrode unit is W G. The electrode width of a main electrode of the third pixel electrode unit is W B. W R>W G>W B.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a pixel electrode unit, a display panel and a display device. Background technique [0002] With the rapid development of multimedia technology, display devices have also made great progress, and user requirements have become higher and higher. Therefore, liquid crystal panels have higher and higher requirements for the consistency of color accuracy of each gray scale, especially for each gray scale. It is hoped that the coordinates of the white point can remain the same, so that consumers can truly enjoy lifelike color performance when watching movies. [0003] However, in the color films of general displays, the thickness of the blue film is the largest, followed by the thickness of the green film, and then the thickness of the red film, and the gap between the liquid crystal cells is defined / monitored / measured by the thickness of the green film, so There is a differe...
