Processing method of light guide plate lattice point side mold core, light guide plate mold core and light guide plate

The invention discloses a processing method of a light guide plate lattice point side mold core, a light guide plate mold core and a light guide plate, and the processing method of the light guide plate lattice point side mold core comprises the following steps: firstly, taking a mold core body, grinding one surface of the mold core body, and then processing lattice points on the ground surface of the mold core body, the grinding direction of the mold core body is parallel to the light incidence direction of the light guide plate processed by the mold core, the surface roughness Ra of the ground surface of the mold core body after grinding is greater than or equal to 0.3 mu m and less than or equal to 0.5 mu m, and the dot processing adopts laser processing and/or point striking process processing. According to the light guide plate mold core machined through the method, the light guide plate manufactured through injection molding is good in shielding performance, and the haze effect is good when the light gu
