Problems solved by technology

[0002] The known backlight modules can be mainly divided into direct-type and side-type backlight modules. Take the side-type backlight module as an example. The optical structure at the bottom of the light guide plate will destroy the total reflection of light and make the light leave the light guide plate, and then use the optical film set on the top to increase the brightness of the front and control the viewing angle range. In order to make the light energy of the light guide plate can be The effect of being converged to the positive light emission can be achieved by at least using the lower diffuser and matching two BEFs, but the cost of the optical film set used in this method is relatively high, and the thickness of the optical film is relatively thick. Therefore, it is more important to construct the optical structure at the bottom of the light guide plate, so as to improve its light output effect through the microstructure of the light guide plate; in addition, the manufacture of the light guide plate is often formed by using a precision mold core, so the processing of the mold core is more important
