Embodiment Construction

[0030] The dosing sheet of the present invention and the LCD module using the dosing sheet will be further described in detail below in conjunction with specific embodiments and accompanying drawings.

[0031] Please also see Figures 1 to 4 , a light uniform sheet, which includes a first light guide sheet 11 and a second light guide sheet 12 that can be superimposed on each other. A notch is a regular hexagonal first groove 111, and the second light guide sheet 12 is uniformly formed with a plurality of regular hexagonal second grooves 121 on the side surface facing the first light guide sheet 11; The first groove 111 and the second groove 121 have the same structure.

[0032] The first light guide sheet 11 and the second light guide sheet 12 are superimposed and attached to each other, so that the first groove 111 and the second groove 121 can avoid each other and be staggered, so that the first groove 111 and the second groove 121 are connected in order to form a honeycom...

Abstract

The invention relates to a light evening sheet and an LCD module using the same. A first light guide sheet and a second light guide sheet are integrally laminated to form the light evening sheet, and multiple first grooves and second grooves shaped in an orthohexagonal frustum are formed in connection surfaces of the first light guide sheet and the second light guide sheet respectively, and the first grooves and the second grooves form a cellular light evening area by staggered splicing of the first light guide sheet and the second light guide sheet; after external light enters the light evening sheet, light undergoes scattering, diffuse reflection and refraction inside the light evening sheet continuously with the aid of the principle of light scattering, diffuse reflection and refraction, the loss of light energy is reduced, and the effect of light evening and high transmission rate is achieved. The light evening sheet and the LCD module have the advantages that the mould structure is simple to process, the product is convenient to mould in any shape and is easy to assemble, evening effect is better, and high transmittance is realized.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted electronic products, in particular to a dodging sheet and an LCD module using the dosing sheet. Background technique [0002] At present, the dodging sheet widely used in the automotive electronics industry is usually made of PC sheet, and the surface of the PC sheet is frosted to a certain roughness. When the light passes through the PC dodging sheet, the light Through continuous diffuse reflection, refraction and other optical principles, in order to achieve uniform light effect, this uniform light sheet seriously damages the transmittance of PC material, its transmittance is only below 15%, and there are phenomena of poor brightness and uneven light output . Contents of the invention [0003] The object of the present invention is to provide a dodging sheet and an LCD module using the dosing sheet. [0004] The technical solution adopted by the present invention to solve the above t...
