Embodiment 1

[0028] Such as figure 1 As shown, a hybrid liquid crystal display with high light transmittance includes a TFT display layer, a VA display layer and a diffuser display layer, wherein the diffuser display layer includes a diffuser 5, the VA display layer includes a VA display 2, and the TFT display The layer includes a TFT front polarizer 6; the upper part of the VA display screen 2 is attached with a VA front polarizer 1 using optical glue, and the lower part of the VA display screen 2 is attached with a VA rear polarizer 3 and The film layer 4 is an integrally designed VA rear polarizer layer. The lower part of the VA rear polarizer layer is also bonded with the diffusion sheet 5 in the diffusion sheet display layer and the TFT front polarizer 6 in the TFT display layer. The TFT front polarizer 6 and the diffuser 5 need to be arranged in the same plane, and they are arranged in parallel. Two sets of diffusers 5 are arranged on both sides of the TFT front polarizer 6, and the...

Embodiment 2

[0030] Such as figure 2 As shown, a hybrid liquid crystal display with high light transmittance includes a TFT display layer, a VA display layer and a diffuser display layer, wherein the diffuser display layer includes a diffuser 5, the VA display layer includes a VA display 2, and the TFT display The layer includes a TFT front polarizer 6; a VA front polarizer 1 is attached to the upper part of the VA display screen 2 using optical glue, and a VA rear polarizer 3 is attached to the lower part of the VA display screen 2 using optical glue, while the VA rear polarizer 3 The lower part is pasted with a TFT front polarizer 6 and The TFT front polarizer layer and the diffuser 5 in the diffuser display layer are designed as a whole with the film layer 4. The two sets of diffusers 5 are respectively distributed on both sides of the TFT front polarizer layer, and make the TFT front polarizer layer and the diffuser 5 are in the same plane and arranged parallel to each other, and th...

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...
