Background

The design principle of the light guide plate is derived from a liquid crystal display screen of a notebook computer, and the light guide plate is a high-tech product for converting a linear light source into a surface light source. Optical grade acrylic (PMMA)/PC is used as a base material, and the backlight module technology of an LCD display screen and a notebook computer is applied, so that the light of the light guide plate is refracted into a surface light source uniform light state to manufacture and form the LED backlight module through the high light transmission rate of the light guide points and the calculation of the computer on the light guide points. The existing light guide plate is made of optical acrylic/PC plate, then high-tech materials with extremely high refractive index and no light absorption are used, and light guide points are printed on the bottom surface of the optical acrylic plate by using laser engraving, V-shaped cross grid engraving and UV screen printing technologies. The optical-grade acrylic sheet is used for absorbing the light emitted from the lamp to stay on the surface of the optical-grade acrylic sheet, when the light irradiates each light guide point, the reflected light can be diffused towards each angle, and then the reflected light is damaged and is emitted from the front surface of the light guide plate. The light guide plate can uniformly emit light through various light guide points with different densities and sizes. The reflecting sheet is used for reflecting the light exposed from the bottom surface back to the light guide plate so as to improve the use efficiency of the light; under the condition of equal area brightness, the luminous efficiency is high and the power consumption is low. The light guide plate needs to be installed on the surface of other components after being installed in the equipment shell, and the light guide plate is easy to displace in the process of installing other components, so that the installation precision is influenced.
