Abstract

The embodiment of the invention provides a backlight module preparation method and device. The backlight module preparation method comprises the steps of acquiring a target color saturation visual angle of a display module; wherein a display module comprises a liquid crystal display panel and a backlight module; obtaining a target backlight brightness view angle corresponding to the target color saturation view angle according to the target color saturation view angle, and preparing a backlight module according to the target backlight brightness view angle; when the color saturation visual angle of the liquid crystal display panel needs to be changed; obtaining target color saturation viewing angle, obtaining a target backlight brightness visual angle according to the target color saturation visual angle. The target backlight brightness visual angle is obtained, and then the backlight module is prepared according to the target backlight brightness visual angle, so that the color saturation visual angle can be changed and the color cast can be improved by changing the backlight brightness visual angle in the backlight module, the manufacturing process of the display panel does not need to be changed, and the technical problems of complex manufacturing process and relatively low yield of an existing VA type liquid crystal display panel improvement method are solved.

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...
