Problems solved by technology

However, due to the shorter wavelength of blue light, compared with red light and green light, the phase difference (Retardation) required to achieve the same transmittance (Transmittance) is smaller, and the transmittance-voltage ( V-T) curves are different; moreover, red light, green light and blue light have different transmittances on the polyimide (PI) film, planarization layer (PFA), coating layer (OC) and other film surfaces in the panel, and also Can cause color cast issues

Abstract

The invention relates to a picture element structure improving color cast and a display device applying the same. The picture element structure is characterized by comprising multiple picture element units, wherein each picture element unit comprises at least one transparent area, the effects of the transparent areas are distinguished according to different light path differences and specific area proportions, the picture element structure is circular-shaped, elliptical-shaped and helical-shaped.

Description

technical field [0001] The invention relates to a design method for improving color shift, in particular to a pixel structure for improving color shift and a display device for its application. Background technique [0002] A liquid crystal display panel usually consists of a color filter substrate (Color Filter, CF), a thin film transistor array substrate (Thin Film Transistor Array Substrate, TFT Array Substrate), and a liquid crystal layer (Liquid Crystal Layer, LC Layer) arranged between the two substrates. ), its working principle is to control the rotation of the liquid crystal molecules in the liquid crystal layer by applying a driving voltage on two glass substrates, and refract the light from the backlight module to produce a picture. According to the different orientation methods of liquid crystals, the liquid crystal display panels currently on the mainstream market can be divided into the following types: vertical alignment (Vertical Alignment, VA) type, twisted ...
