Abstract

The invention relates to a glass light guide plate and a manufacturing method thereof. The glass light guide plate comprises upper glass and lower glass, wherein the lower surface of the upper glass is attached to the upper surface of the lower glass; uniform quantum dots are coated on the lower surface of the upper glass in a vacuum evaporation manner; a diffusion layer used for diffusing and atomizing light rays is coated on the upper surface of the upper glass; and an optical dot layer used for converting a line light source into an area source is arranged on the lower surface of the lower glass. The glass light guide plate is widely applied to an edge-lighting backlight module of a blue LED lamp and replaces the traditional PMMA (Polymethyl Methacrylate) or MS light guide plates, quantum films are replaced, and aluminum backplanes are canceled, so that the TV module is developed to be ultrathin and ultra-high-definition; meanwhile, the properties of the light guide plate are remained, the optical dot design can be performed on the premise of optimizing the macroscopic color saturation, the uniformity of the picture is optimized, and the glass light guide plate has significances in ultrathin and ultrahigh color range TV modules.

Description

technical field [0001] The invention relates to a glass light guide plate and a manufacturing method thereof. Background technique [0002] Traditional LCD TVs use acrylic light guide plates, which are generally 2-4mm thick. With the addition of aluminum backplanes, the overall thickness will exceed 1cm, which makes it difficult for designers to reduce the thickness of the TV; but the latest structure uses glass For the light guide plate, the glass light guide plate and the reflector are bonded together with UV-cured pressure-sensitive adhesive to form the light guide plate assembly. The optical and mechanical properties of this assembly are better than the traditional acrylic light guide plate assembly; The high mechanical performance of itself can eliminate the use of the aluminum back plate, making the LCD TV thinner, the thinnest can be less than 5mm, reducing the thickness of the TV by 70% and the weight of the TV by 30%. On existing liquid crystal displays, as the req...
