Light guide plate (light guide plate) is the use of optical grade acrylic / PC sheet, and then with a very high refractive index and does not absorb light of high-tech materials, in the optical grade acrylic sheet bottom with laser engraving, V-shaped cross grid engraving, UV screen printing technology printed on the light guide points. The use of optical grade acrylic sheet to absorb the light from the lamp to stay on the surface of the optical grade acrylic sheet, when the light is shot to each guide point, the reflected light will spread to all angles, and then destroy the reflection conditions by the front of the light guide plate shot. Through a variety of sparse, varying size of the light guide points, the light guide plate can be made uniform light. The use of reflective sheet is to reflect the light exposed on the bottom side back to the light guide plate, used to improve the efficiency of the use of light; the same area luminous brightness, high luminous efficiency, low power consumption. Single-sided microstructure array light guide plate generally uses the extrusion molding process.
