Problems solved by technology

Therefore, there is also a certain thickness difference between different first substrates
Therefore, although the cell pitch of different liquid crystal cells after assembly, that is, the distance between the first substrate and the second substrate, is uniform, the overall thickness of the liquid crystal cells varies greatly, and the existing thinning technology cannot eliminate the difference. There is a thickness difference in the overall thickness of the liquid crystal cells, and the overall thickness difference of different liquid crystal cells will have different effects on the optical characteristics of the liquid crystal display substrate, and in the subsequent cutting and splitting process, there may be a large difference in the overall thickness of the liquid crystal cell There are problems such as burrs on the edge of the first substrate or the second substrate when the cutting is incomplete or split on the first substrate or the second substrate; and the fragmentation occurs on the first substrate or the second substrate with a small difference in the overall thickness of the liquid crystal cell. question

Description

technical field [0001] The invention relates to the technical field of liquid crystal display manufacture, in particular to a liquid crystal cell thinning method and liquid crystal cell thinning equipment. Background technique [0002] With the wide application of liquid crystal displays, people have higher and higher requirements for liquid crystal displays. In addition to requiring high brightness, high contrast, high resolution, high color saturation and fast time response, another issue that liquid crystal displays face It is thinning, and the key component liquid crystal box in the liquid crystal display is an important factor for the thinning of the liquid crystal display. The liquid crystal cell is composed of a first substrate and a second substrate bonded together, and an optically active substance, such as liquid crystal, is arranged inside it. Since the proportion of the first substrate and the second substrate is large, and it is necessary to ensure mechanical s...
