Description

Technical Field

[0001] The invention relates to the field of backlight module display vision, and in particular to a backlight for adjusting a light-increasing angle and an adjusting method. Background Art

[0002] In the LCM display industry, the backlight module is an important part of the liquid crystal display. The luminous effect of the backlight module will directly affect the user's visual perception, and the angle of the light-enhancing film is the key to the display effect of the module. Therefore, the angle of the light-enhancing film needs to be adjusted to match the FOG to ensure that the backlight and FOG have no interference patterns, water ripples, or rainbow patterns when they are lit. Usually, we assemble the semi-finished backlight and cover it with FOG for debugging. When the angle is not suitable and there are interference patterns, turn the FOG for debugging. Since there are steps in the backlight glue frame or glue iron, there will be a height difference when turning the FOG to debug the angle, which affects the visual effect. Therefore, we need a new backlight display device and angle debugging method. Summary of the invention
