Abstract

The invention provides a luster adding sheet, which comprises a luster adding sheet body, a front coating and a back coating, wherein the front coating covers the front side of the luster adding sheetbody; the back coating covers the back side of the luster adding sheet body. The luster adding sheet uses the proper materials; the front coating and the back coating are respectively covered on thefront side and the back side of the luster adding sheet; the luster adding effect of the obtained luster adding sheet is 10 to 20 percent higher than that of the ordinary luster adding sheet; meanwhile, the material is cheap and can be easily obtained; the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a brightness enhancement sheet. Background technique [0002] Enhancement film is widely used in notebook computers, LCD monitors, LCD TVs, portable DVD players, car navigation systems, touch-screen mobile phones, digital cameras, digital video equipment, etc. [0003] If it is assembled in front of the backlight, and the light emitted by the light source is concentrated toward the user of the display device, the front brightness can be increased by about 100% (in the case of two orthogonal use, there are horizontal and vertical BEF). Moreover, the unused light outside the angle of view is recycled according to the light re-reflection effect, and is gathered to the user at the most appropriate angle. However, the existing brightness enhancement sheet still has the problem that the increase in brightness cannot meet the requirements, and the performance needs to be further impr...
