Problems solved by technology

When the amount of liquid crystal is too much, when the liquid crystal is heated and expanded, or the liquid crystal at the edge of the pixel area is too much after the vacuum box is assembled, the liquid crystal 8 will be in contact with the sealing glue 4, such as figure 2 As shown, the interaction occurs under certain conditions, causing liquid crystal contamination
In addition, in the vacuum box, under the action of strong electrostatic adsorption and atmospheric pressure, the partial spacer and glass fiber behind the box will be deformed due to excessive force, making the LCD box thicker. Uniformity, resulting in edge Mura (a general term for poor picture quality) and other defects, which have varying degrees of impact on the display quality and yield of LCD screens

Abstract

The present invention discloses a panel of a liquid crystal display device, which comprises a colorful film base panel and an array base panel which is arranged relatively; wherein, the thickness of a box between the colorful film base panel and the array base panel is kept by shock insulators; liquid crystal is filled between the colorful film base panel and the array base panel; a frame sealing glue which is arranged around the pixel areas of the colorful base panel and the array base panel seals the two base panels; wherein, an inner layer insulation frame and an outer layer insulation frame are arranged between the edges of the pixel areas and the frame sealing glue; one side or a plurality of sides of the inner layer insulation frame forms or form a series of grooves. Through arranging the insulation frame in the structure of two layers between the pixel areas and the sealing glue of the panel of the liquid crystal display device, the panel of the liquid crystal display device can profitably control the quantity of the liquid crystal in the pixel areas, thereby avoiding the mutual function between the liquid crystal and the frame sealing glue. The thickness of the liquid crystal box is well stabilized, and further the display effect of the liquid crystal panel is improved.

Description

technical field [0001] The present invention relates to a liquid crystal display (TFT LCD), in particular to a panel of a liquid crystal display. Background technique [0002] Liquid crystal display (LCD) products have developed very rapidly in recent years, and its application fields are also constantly expanding. More and more high-quality LCD displays are gradually listed; at the same time, there are many problems, such as the interaction between liquid crystal and sealant. Liquid crystal contamination occurs, due to the uneven thickness of the pixel edge box, resulting in poor image quality when the LCD screen is displayed. [0003] figure 1 It is a schematic top view of the liquid crystal display panel structure in the prior art; figure 2 Yes figure 1 Schematic cross-sectional view of the middle edge. like figure 1 and figure 2 As shown, the liquid crystal display panel in the prior art includes a color filter substrate 1 and an array substrate 2 arranged opposi...
