Abstract
The invention discloses a manufacturing technique of a sidelight type glass backlight plate. By adopting a special high-pressure air sand blower technology, more than 200 meshes of silicon carbide sand is sprayed to the surface of a glass; after sand blowing process, a protective oil ink is peeled off to form a reflective face with a sand blowing zone and a transparent reflective lattice; meanwhile, by adopting the high-pressure air sand blower technology, more than 5000 meshes of super-fine silicon carbide sand is sprayed to a light source output face, and countless nanoscale atomizing concaves are formed on the light source output face; subsequently, a mixed acid solution leading by hydrofluoric acid is applied to perform comprehensive etching process on the whole sand blowing zone and the transparent reflective lattice without sand blowing. The surface after anti-dazzle treatment forms a diffuse reflection layer which is not easy to transmit; light projected from a light source incident face only can be clamped in a passage between two anti-dazzle layers, and repeatedly refracted and reflected by the reflective lattice, thus a reflective refraction point is formed, and the reflective refraction point has simpler reflective technique and higher refraction rate of a back liner reflective film by comparing with a printing reflective point on an acrylic light guide plate.
