Problems solved by technology

This fixing method is prone to bumps and bulges in low-pressure areas, which makes the projection display screen uneven and affects the viewing effect. At the same time, the use of two layers of foam glue increases the thickness of the projection display screen, which is beneficial to the realization of Ultra-thin projection display screen is restricted
[0004] The above two kinds of projection screens not only have poor imaging effect, but also affect the viewing effect. The structure is complicated, and only one-sided viewing can be realized, and it is easy to cause eye fatigue, which cannot meet the market demand.

Abstract

The invention relates to technical field of image projection, in particular to a glass display screen and a preparation process thereof. The glass display screen comprises a glass display screen body,wherein a film layer is arranged on the glass display screen body and comprises, by mass, 30-40 parts of leadless glaze, 20-65 parts of wollastonite, 20-30 parts of kaolin, 30-50 parts of dolomite, 10-30 parts of calcium carbonate, 10-30 parts of talcum, 10-30 parts of zinc silicate, 10-15 parts of silicon dioxide, 30-40 parts of calcite, 10-15 parts of silicon dioxide, 10-15 parts of magnesium oxide, 20-30 parts of sodium citrate and 10-30 parts of sodium hexametaphosphate. The glass display screen is prepared through glass display screen raw glass cutting, side length grinding, film printing and tempering. The glass display screen is simple in structure, good in imaging effect, capable of achieving double-side viewing, difficult to cause eye fatigue, capable of satisfying market requirements and widely applicable.

Description

technical field [0001] The invention relates to the technical field of image projection, in particular to a glass display screen and a preparation process thereof. Background technique [0002] At present, the optical screens used for projectors on the market are mainly divided into hard screens and soft screens. The fixing method of the soft curtain is mainly to use elastic objects such as springs and elastic ropes to make the curtain form a plane and fix it on the surrounding frame. The fixing method of the hard curtain is mainly to paste the optical curtain on the surface of a rigid object (such as honeycomb aluminum plate, aluminum-plastic plate, steel plate, etc.), and then assemble a frame around the rigid object for covering and decoration. Projection products have high requirements on the flatness and light resistance of the screen. Due to the poor light resistance of the soft screen itself and its fixing method, it is difficult to meet the flatness requirements; wh...
