Problems solved by technology

The brushing alignment method can provide a strong alignment ability of liquid crystal molecules, but in the process of brushing, due to the use of flannelette contact friction, static electricity and particle pollution will be generated, and these pollutions often directly cause damage to liquid crystal elements

Embodiment 1

[0030] A liquid crystal display comprising:

[0031] Multiple square pixel structures, each square pixel structure is composed of red sub-pixels, green sub-pixels and blue sub-pixels, each square pixel structure is divided into four square sub-regions of equal size, the blue sub-pixels A pixel occupies two adjacent sub-regions, and the area of ​​the blue sub-pixel is twice that of the red or green sub-pixel. Among them, the blue sub-pixels rely on the backlight to emit light, and the square pixel structure is arranged in an array.

[0032] The preparation method of the liquid crystal display is as follows: according to the commonly used TFT-LCD manufacturing process, the color filter and the array substrate are prepared and surface treated respectively;

[0033] Among them, before the color filter substrate is coated with the alignment layer, the RGB color film is prepared by materials doped with quantum dots. The transparent photoresist material of quantum dots, the doping ...

Abstract

The invention discloses a liquid crystal display which comprises a plurality of square pixel structures. Each square pixel structure comprises a red sub-pixel, a green sub-pixel and a blue sub-pixel and is divided into four square sub-regions with the equal sizes, and the area of each blue sub-pixel is two times the area of each red sub-pixel or each green sub-pixel. The liquid crystal display has the advantages that the areas of blue pixels can be enlarged by the square pixel structures, and accordingly the blue light efficiency can be improved; the square pixel structures and blue light excitation quantum dots are combined with one another, and accordingly the liquid crystal display is high in exposure accuracy, color saturation, contrast, response speed and resolution, wide in visual angle and free of color cast without increase of extra cost.

Description

technical field [0001] The invention belongs to the field of liquid crystal displays, and relates to a liquid crystal display and a preparation method thereof. Background technique [0002] A liquid crystal display (LCD) includes a CF (color filter, color filter) substrate and an Array (array) substrate, and transparent electrodes exist on the inner side of the substrate. A layer of liquid crystal molecules is sandwiched between the two substrates. The liquid crystal display controls the orientation of the liquid crystal molecules through the electric field to change the polarization state of light, and realizes the penetration and blocking of the light path by the polarizer to achieve the purpose of display. [0003] TFT-LCD (Thin Film Transistor Liquid Crystal Display) has gradually occupied a dominant position in the display field due to its low power consumption, excellent picture quality, and high production yield. Currently, LCD panels are mainly divided into VA (vert...
