Problems solved by technology

like figure 1 , figure 2 As shown, when the liquid crystal molecules of a pixel change from a white gray scale to a middle gray scale, due to the increase of the anisotropy of the liquid crystal refractive index, the transmittance of red light also increases, and the color of the LCD seen by the human eye is not White is yellowish, and there is a light yellow color cast (called Yellowish), which affects the quality of the display screen

Embodiment Construction

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0019] The transflective color pixel structure provided by the embodiment of the present invention includes red sub-pixels, green sub-pixels and blue sub-pixels, and the aperture ratio of the blue sub-pixels is higher than that of the red sub-pixels.

[0020] Further, based on the light transmission area of ​​the green sub-pixel as 100%, the light transmission area of ​​the red sub-pixel is 93% to 100% of the light transmission area of ​​the green sub-pixel, an...

Abstract

The invention provides a half-transmitting half reflecting color pixel structure, a color film substrate, a liquid crystal display panel and a display device and belongs to the field of liquid crystal display production. A transmitting area of a blue subpixel in each of pixels is enlarged, and a transmitting area of a red subpixel is reduced, so that a faint yellow color partial phenomenon caused by the increase of transmissivity of red color with long wavelengths is avoided during the process that the pixel moves from a white gray scale to a middle gray scale. The half-transmitting half reflecting color pixel structure comprises the red subpixel, a green subpixel and the blue subpixel, and an aperture opening ratio of the blue subpixel is higher than that of the red subpixel.

Description

technical field [0001] The invention relates to the field of liquid crystal display manufacture, in particular to a transflective color pixel structure, a color filter substrate, a liquid crystal panel and a display device. Background technique [0002] At present, TFT-LCD (Thin Film Transistor-Liquid Crystal Display, Thin Film Field Effect Transistor Liquid Crystal Display) is the mainstream display used in mobile phones and other products. With the wide application of portable information terminal electronic equipment such as mobile phones and other indoor and outdoor dual-use characteristics, it is often necessary to use a semi-transparent and semi-reflective liquid crystal display. Transflective liquid crystal display means that part of each pixel of the liquid crystal display panel is a reflection area, and the other part is a transmission area, which is displayed in the transmission area when the external ambient light is weak, and in the case of strong external ambien...
