Abstract

The invention provides a high-transmittance mixed liquid crystal display screen which comprises a TFT display layer, a VA display layer and a diffusion sheet display layer, the diffusion sheet displaylayer comprises a diffusion sheet, the VA display layer comprises a VA display screen body, a VA front polarizer is attached to the upper portion of the VA display screen body, and a VA rear polarizer layer integrally designed with a thin film layer is attached to the lower portion of the VA display screen body. The lower portion of the VA rear polarizer layer is attached to a diffusion sheet inthe diffusion sheet display layer, the TFT display layer comprises a TFT front polarizer, the TFT front polarizer and the diffusion sheet in the diffusion sheet display layer are arranged in the sameplane in parallel, and a TFT display screen and a TFT rear polarizer are sequentially attached to the lower portion of the TFT front polarizer. The thin film layer with the specific angle is overlaidin the display screen so that the light transmittance of the hybrid display screen is improved, the display area has high brightness, and a good visual effect is provided.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted liquid crystal displays, in particular to a hybrid liquid crystal display with high light transmittance. Background technique [0002] VA liquid crystal (Vertical Alignment liquid crystal) display is the abbreviation of Vertical Alignment liquid crystal, which has technical advantages such as high contrast, mild color temperature, low light leakage and wide viewing angle, which can effectively improve the color loss of TN liquid crystal (Twisted Nematic liquid crystal) display. Question: Compared with TN LCD, VA LCD has higher contrast and wider viewing angle, and is the mainstream technology used in large-screen LCD TVs today. [0003] TFT liquid crystal (Thin Film Transistor liquid crystal) display is a thin film transistor liquid crystal display, that is, "true color" (TFT). TFT liquid crystal has a semiconductor switch for each pixel, and each pixel can be directly Control, so each no...
