Problems solved by technology
Therefore, quite serious light loss will be caused, and then the luminance of the liquid crystal display module 100 will be greatly reduced.
[0009] Furthermore, since the flexible circuit board 114 has to be folded twice during assembly, such an assembly method is likely to cause a gap between the reflective sheet 112 and the light guide plate 110
Therefore, the probability of particles entering between the reflection sheet 112 and the light guide plate 110 is greatly increased, which will seriously affect the product yield of the liquid crystal display module 100
[0010] What's more, since the flexible circuit board 114 has to be folded twice, the material of the flexible circuit board 114 will be wasted
Therefore, such a design will increase the production cost
