Abstract

The embodiment of the present application provides a backlight module preparation method and device, the backlight module preparation method includes obtaining the target color saturation viewing angle of the display module; the display module includes a liquid crystal display panel and a backlight module; according to the Target color saturation viewing angle, obtain the target backlight brightness viewing angle corresponding to the target color saturation viewing angle, prepare a backlight module according to the target backlight brightness viewing angle; when the liquid crystal display panel needs to change the color saturation viewing angle, obtain the target color saturation degree viewing angle, and then obtain the target backlight brightness viewing angle according to the target color saturation viewing angle, and then prepare a backlight module according to the target backlight brightness viewing angle, so that by changing the backlight brightness viewing angle in the backlight module, the color saturation viewing angle can be changed, and the color saturation can be improved. It does not need to change the manufacturing process of the display panel, and solves the technical problems of complex manufacturing process and low yield rate in the existing improvement method of VA-type liquid crystal display panel.

Description

technical field

[0001] The present application relates to the field of display technology, in particular to a method and device for preparing a backlight module. Background technique

[0002] The display modes of existing liquid crystal display panels include TN (Twisted Nematic, twisted nematic type), IPS (In-Plane Switching, in-plane switching type), VA (Vertical Alignment, vertical alignment type). , fast response time, no need for frictional alignment, and is widely used, but VA-type liquid crystal display panels have color shift problems, and the picture quality is poor when viewed from the side, and in the use of VA-type liquid crystal display panels, there will be a problem with the viewing angle Requirements, the color saturation viewing angle of the liquid crystal display panel needs to be modified, so the VA type liquid crystal display panel needs to be improved, but the existing improvement process is complicated and the yield rate is low.

[0003] Therefore, the...
