Liquid crystal display panel

Abstract

The invention relates to a liquid crystal display panel, which comprises a color optical filter substrate, an array substrate and an insulating and cushioning materials which are positioned between the color filter substrate and the array substrate, wherein the density of the insulating and the cushioning material in the middle part of the liquid crystal display panel is greater than that of the insulating and the cushioning material on the peripheral part of the liquid crystal display panel. In the liquid display panel, the arrangement of the internal insulating and cushioning material is changed by arranging the insulating and cushioning material with high density in the middle part and arranging the insulating and cushioning material with low density in the peripheral part of the liquidcrystal display panel, so the pressure bearing capacity of the middle part is improved, the box thickness of the liquid crystal display panel is retained, and the display quality of the TFT-LCD is improved.

Description

technical field [0001] The present invention relates to the field of thin film transistor-liquid crystal display (Thin Film Transistor-Liquid Crystal Display, hereinafter referred to as: TFT-LCD) manufacturing field, in particular to a liquid crystal display panel. Background technique [0002] At present, TFT-LCD is the mainstream of flat panel displays, and has the advantages of low power consumption, low manufacturing cost and no radiation. The TFT-LCD panel is composed of a color filter substrate and an array substrate. Spacers are used to isolate the liquid crystal injection gap between the two substrates, and a sealant is used to complete the packaging of the liquid crystal in the surrounding part between the two substrates. . The principle of TFT-LCD is to use the dielectric anisotropy and conductive anisotropy of liquid crystal molecules, and apply an electric field to switch the alignment state of liquid crystal molecules, resulting in various photoelectric effects...

Problems solved by technology

In fact, for touch-type liquid crystal display screens, due to the existence of atmospheric pressure and the gravity of the panel glass itself, the pressure on the columnar spacers in the middle of the panel is greater than that of the peripheral parts, and the columnar spacers in the middle may be depressed, even It is crushed, so it is prone to sag in the middle of the panel, which is manifested as uneven display of the LCD screen

The larger the size of the LCD panel, the greater the gravity of the panel glass itself, and the more difficult it is to maintain a uniform and stable cell thickness

Moreover, even if it is not a touch screen, it is difficult to prevent the user from pressing on the surface of the LCD screen, that is to say, the panel is often subjected to external pressure during use.

For the same pressure, it will cause greater damage to the middle part than the peripheral part, and the middle part is difficult to recover

Since the peripheral part is not only supported by the sealing glue, but also supported by functional modules, the depressed middle part is more difficult to restore
