Embodiment Construction

[0012] The invention discloses a light diffusion sheet, combined with figure 2 As shown, consistent with the prior art, 1. The light diffusion sheet includes a transparent base plate 2, one side of the base plate 2 is coated with a resin layer 1, and the other side of the base plate 2 is printed with an ink layer 3, and the ink layer 3 is printed on the base material. The surface of the plate 2 forms a circumference.

[0013] The difference is that the outer edge of the ink layer 3 forms an inclined surface 32 , and the inclined surface 32 of the ink is sunk behind the side end surface 33 of the base plate 2 . Specifically, inset means that the oblique surface is inclined behind the side end surface 33 of the base plate 2 . Due to the structure of the ink slope 31 , during application, the missing corners of the ink caused by rubbing will not cause the ink to fall off and cause whitening, which will eventually affect the actual performance of the light diffusion sheet.

Abstract

The invention provides a light diffusion sheet and a trimming method thereof. The light diffusion sheet comprises a transparent base board. One surface of the base board is coated with a resin layer, the other surface of the base board is coated with an ink layer, the ink layer forms a circumferential circle on the surface of the base board, an inclined plane is formed at outer edge of the ink layer, and the inclined plane of the ink recesses to the back of the lateral end face of the base material board. The light diffusion sheet trims towards the resin layer from one surface of the base material board to prevent out-protruding ink trimming edges of the non-halogen ink layer from causing troubles of dropping, whitening, unfilled corners and cracking of the ink edges when put in use while avoiding leaking-out problem in use.

Description

technical field [0001] The invention relates to a light diffusion sheet, in particular to a light diffusion sheet with a slope and the ink on the product surface is not easy to fall off. Background technique [0002] In display screens such as LCDs and projectors, light diffusion sheets are used to allow observers to observe images with a wide viewing angle. The structure of the light diffusion sheet is a transparent substrate plate covered with a synthetic resin layer. The synthetic resin layer is formed of beads with different sizes and particle sizes. The light is refracted through the substrate plate and the resin layer to form a diffusion effect. [0003] In actual use, the light diffusion sheet is printed with halogen-free ink on the periphery of its surface as needed to prevent light leakage and bright lines during use. Then, print a frame along the ink on one side of the base plate, and use it after cutting as needed. like figure 1 As shown, the cutter 4 cuts upwa...
