Abstract

The invention provides a glass light guide plate and a manufacturing method thereof, and relates to the technical field of glass processing. The glass light guide plate comprises a glass plate and a reflecting film, wherein the glass plate has two opposite surfaces namely a front surface and a bottom surface respectively, a plurality of light guide spots are printed on the bottom surface of the glass plate by using laser, the reflecting film is adhered to the bottom surface printed with the light guide spots, and the front surface of the glass plate is a lumpy rough surface. The glass light guide plate provided by the invention is high in strength, low in production cost and lightweight and thin in base material.

Description

technical field [0001] The invention belongs to the field of glass processing, and in particular relates to a glass light guide plate and a manufacturing method thereof. Background technique [0002] Light guide panel (Light guide panel) is an optical device that efficiently converts point light source or line light source into uniform surface light source. Light guide plates are widely used in various optical display devices and are an important part of various types of backlights such as LCDs. Generally, an optical acrylic plate is used as the carrier of the light guide plate device. The existing light guide plate material is mainly polymethyl methacrylate (acrylic), its strength is low, and it is easy to yellow after a period of use and affect the light guide effect; the cost of optical grade acrylic plate is high, and it will cause machine ( Computers, TVs, etc.) equipment is thicker, which does not conform to the trend of ultra-thin electronic products.
