When the light hits each light guide point, the reflected light will diffuse to all angles, and then destroy the reflection condition and be emitted from the front of the light guide plate. Through various light guide points of different densities and sizes, the light guide plate can emit light evenly. The purpose of the reflective sheet is to reflect the light exposed from the bottom back into the light guide plate to improve the efficiency of light use; under the condition of equal area luminous brightness, the luminous efficiency is high and the power consumption is low.
