Embodiment Construction
[0012] see figure 2 , is a flow chart of the manufacturing method of the light guide plate of the present invention, comprising the following steps: providing a polished mold core substrate (step 22); using a laser beam, marking the designed light guide plate dot pattern on the polished mold Form a light guide plate mold core on the core substrate (step 24); use the mold core to injection mold the light guide plate, that is, form a preset dot pattern on the light guide plate (step 25).
[0013] see image 3 , is a schematic diagram of the process of laser scribing the mold core substrate in the light guide plate manufacturing method of the present invention. Under program control, the laser emitting system 40 emits laser light 70 to mark dots on the mold core substrate 60 . According to the designed dot pattern of the light guide plate, in a specific small area of the mold core, the laser with the same power and beam radius is used to mark the dots, so as to ensure the con...
