Embodiment Construction

[0015] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0016] As shown in FIG. 3 , a liquid crystal dripping method determines the liquid crystal dripping position according to a dripping array, and the dripping array is I-shaped. Wherein, an inclined transition portion is provided between the two ends of the infusion array and the middle portion.

[0017] Through experiments, it is found that the cell thickness unevenness caused by liquid crystal dots has obvious screen dependence and position dependence. Screen dependence means that the screens with uneven cell thickness are only concentrated on certain sides of the LCD screen and not all sides of the LCD screen have uneven cell thickness; position dependence means that although the cell thickness is uneven on certain sides It occurs in all LCD screens, but the position where the cell thi...

Abstract

The invention relates to a crystalline dripping method based on the I shape dripping matrix to determine the dripping location. Since the dripping of the crystalline to its attachment with the air, all the crystalline drops connected together, forming an even crystalline layer in the middle of the screen, with the atmospheric pressure applied on the crystalline screen, offsetting the shocking force of the ball shape washer contacting with the crystalline layer in an all around manner, restraining the movement of the ball shape washer to prevent the unevenness of the box thickness.

Description

technical field [0001] The invention relates to a liquid crystal dripping method in the manufacture of a liquid crystal display panel. Background technique [0002] In view of the shortcomings of the traditional liquid crystal injection process, such as long liquid crystal injection cycle, low liquid crystal utilization rate, and high equipment introduction cost, ODF (liquid crystal drop injection) process is mostly used in the production engineering of large-size panels. This process is to drop a certain amount of liquid crystal on the TFT (Thin Film Transistor) substrate first, then align the TFT substrate and the CF (Color Film) substrate in a vacuum, and then bond them together, and then form them by thermal curing of the sealant. The process of LCD screen. This process can greatly shorten the time of liquid crystal injection and improve the utilization rate of liquid crystal. By precisely controlling the amount of liquid crystal, the cell thickness of the liquid crysta...
