Liquid crystal display screen backlight plate manufacturing and forming method

Abstract

The present invention provides a liquid crystal display screen backlight plate manufacturing and forming method, a liquid crystal display screen backlight plate manufacturing and forming device is adopted in the liquid crystal display screen backlight plate manufacturing and forming method, the liquid crystal display screen backlight plate manufacturing and forming device comprises a base, a film covering unit and a cutting unit, the film covering unit is arranged on the inner side wall of the base; and the cutting unit is arranged on the right side of the laminating unit. The method can solve the problems that a protective film is pasted on a backlight plate in a manual operation mode during forming processing at present, deviation is not likely to occur due to manual pasting, the protective film cannot be effectively flattened, so that the protective film is likely to be wrinkled, the backlight plate is likely to be damaged when the protective film is pasted, and the cost is wasted; and the problems that fixed-length cutting cannot be carried out on the protective film in a manual operation mode, incomplete cutting is likely to be caused, secondary pasting and covering need to be carried out on the protective film, the workload is increased, and the working efficiency is affected are solved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display screen processing, in particular to a manufacturing and molding method for a liquid crystal display screen backlight plate. Background technique [0002] The backlight is a light source device used to ensure that the back of the liquid crystal display is bright, that is, in the process of manufacturing liquid crystal LCD, a high-brightness illuminant with a combination of fluorescent lamps and reflectors is added to the back of the liquid crystal LCD. Since the liquid crystal display itself is transparent and will not It emits light, so it needs a backlight to assist, so the brightness and uniformity of the backlight have a direct impact on the performance of the liquid crystal display; the optical characteristics, size and relative position of each component of the backlight have a direct impact on the overall optics of the backlight. The performance is interlocking and has a close...

AI Technical Summary

Problems solved by technology

[0003] However, the following problems exist in the molding process of backlight panels at present: most of the current backlight panels are manually applied to the protective film during the molding process, but manual application is not prone to deviation, and cannot be effectively applied The protective film is flattened, so it is easy to cause wrinkles on the protective film, and it is easy to cause damage to the backlight when the protective film is attached, thereby wasting costs; and the protective film cannot be cut to length by manual operation, and it is easy to cause The cutting is incomplete, so it needs to be pasted twice, which increases the workload and affects work efficiency
