Embodiment 1

[0060] In the projection screen provided by the present invention, a white reflective film with a thickness of 188 μm is selected as the reflective layer, and the reflectivity of the white reflective film is 95.55%. Acrylic resin adhesive is coated on the surface of the reflective layer, and the thickness of the adhesive layer is 5 μm. The layer is combined with the reflective layer through the adhesive layer. The substrate of the refractive layer is PET material with a thickness of 150 μm. In the microprism structure: the height of the prism strip is 55 μm, and the side of the prism strip is an isosceles right angle triangle.

Embodiment 2

[0062] In the projection screen provided by the present invention, a white reflective film with a thickness of 200 μm is selected as the reflective layer, and the reflective rate of the white reflective film is 96.55%. Epoxy resin adhesive is coated on the surface of the reflective layer, and the thickness of the adhesive layer is 8 μm. The refractive layer is combined with the reflective layer through the adhesive layer. The base material of the refractive layer is PC material with a thickness of 100 μm. waist triangle.

Embodiment 3

[0064] In the projection screen provided by the present invention, a silver reflective film with a thickness of 75 μm is selected as the reflective layer, and the reflectivity of the silver reflective film is 99%, and an acrylic resin adhesive is coated on the surface of the reflective layer, and the thickness of the adhesive layer is 25 μm. The layer is combined with the reflective layer through the adhesive layer. The base material of the refraction layer is PMMA material of 75 μm. In the microprism structure: the height of the prism strip is 55 μm, and the side of the prism strip is an isosceles right triangle with a right angle at the apex.

Abstract

The invention relates to the fields of projected display technology and laser television display technology, in particular to a projection curtain with high luminance gains and wide view angles. The projection curtain with the high luminance gains and the wide view angles solves the problems that existing projection curtains can not achieve high luminance gains and wide view angles. The projection curtain comprises a reflection layer, an adhesive layer and a refraction layer. The reflection layer is provided with a reflection surface. The refraction layer comprises a transparent base material and a microprism structure. The adhesive layer is located between the reflection surface of the reflection layer and the transparent base material of the refraction layer. The projection curtain has the effects of high luminance gains and wide view angles and can be applied to laser televisions and projector products.

Description

technical field [0001] The invention relates to the fields of projection display technology and laser TV display technology, in particular to a projection screen with high luminance gain and wide viewing angle. Background technique [0002] In recent years, as people continue to put forward new requirements for the visual effects of displays, liquid crystal displays with the highest market share in the display market have also encountered a bottleneck in their development. Due to limitations in the design and principle of liquid crystal displays, liquid crystal displays cannot achieve large-size, high-color gamut, and more realistic display effects. Therefore, some large display companies are constantly developing new products to replace liquid crystal displays, such as OLED display technology, laser TV display technology and now relatively mature projector technology. Among them, the OLED display technology is not mature enough, and its cost and service life are limited. A...
