Liquid crystal dropping method and device

Abstract

The invention discloses a liquid crystal dropping method and device. The method comprises the steps that the drop numbers of liquid crystals of the outermost periphery are obtained through calculation according to the distance region [m,n] between a circumference of an ellipse and the liquid crystals, wherein m stands for the minimum distance between the liquid crystals, and n stands for the maximum distance between the liquid crystals; coordinates of the liquid crystals of the outermost periphery are obtained according to a relational expression of the ellipse and the drop numbers of the liquid crystals of the outermost periphery; the drop numbers and the coordinates of liquid crystals between the first liquid crystal and the second liquid crystal are obtained according to the coordinates of the first liquid crystal and the second liquid crystal, wherein, the first liquid crystal and the second liquid crystal serve as the liquid crystals of the outermost periphery, and the first liquid crystal and the second liquid crystal are symmetric about the coordinate axis; the liquid crystals are dropped down according to the coordinates of the liquid crystals. By means of the liquid crystal dropping method, the distances from the liquid crystals to the frame are even, and cross contamination between part of the liquid crystals and the frame and uneven diffusion of part of the liquid crystals are avoided.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a liquid crystal dropping method and device. Background technique [0002] A liquid crystal display (Liquid Crystal Display, LCD) screen is formed by bonding a thin film transistor (Thin Film Transistor, TFT) substrate and a color filter substrate (Color Filter, CF) substrate. The manufacturing process of the liquid crystal display mainly includes three major manufacturing processes: array (Array), color filter (CF) and cell (CELL). In the manufacturing process of the CELL segment, liquid crystals need to be dropped on the TFT substrate or CF substrate and then bonded. The widely used LCD screens are usually regular rectangles, and the liquid crystal dripping method used is the matrix dripping method. It is only necessary to determine the center of the rectangle, the long and short sides of the rectangle, and the number of drops of liquid crystals to obtain the following: ...

AI Technical Summary

Problems solved by technology

For an oval liquid crystal display, if the matrix drop method is still used to drop liquid crystal on the TFT substrate or CF substrate, the following will appear: figure 2 In the dripping effect shown, the liquid crystals on the four vertices of the matrix composed of liquid crystals are too close to the frame 110 to cause cross-contamination between the frame 110 and the liquid crystals, and the liquid crystals in the middle of the four sides of the matrix composed of liquid crystals are far from the frame 110 is too far away, resulting in uneven diffusion and affecting the quality of the LCD screen
