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

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 (LiquidCrystalDisplay, LCD) screen is formed by laminating a thin film transistor (ThinFilmTransistor, TFT) substrate and a color filter substrate (ColorFilter, CF) substrate. The manufacturing process of liquid crystal display mainly includes three major manufacturing processes: array (Array), color filter (CF) and cell (CELL). In the process of the CELL section, it is necessary to drop the liquid crystal on the TFT substrate or the CF substrate for lamination. Now widely used LCD screens are usually regular rectangles, and the corresponding liquid crystal dropping method is the matrix dropping method. It only needs to determine the center of the rectangle, the long and short sides of the rectangle and the number of drops of the liquid crystal to be dropped as follows figur...
