Embodiment 1-9

[0179] The invention provides an anti-environmental light laser TV screen, which comprises a light-inducing layer, an adhesive layer, a diffusion layer, a filter layer, a prism layer and a reflection layer sequentially from top to bottom. The light-inducing layer sequentially includes a light-inducing structure and a polymer film from top to bottom. The light-absorbing structure includes two groups of optical units, one is a light-absorbing triangular prism array distributed along the normal direction of the screen, and the other is a light-harvesting concave lens array connected to the light-absorbing columns perpendicular to the screen normal direction. The thickness range of the light-inducing structure is 50-800nm. The thickness range of the polymer film is 25-250 μm. The light-harvesting concave lens array in the light-absorbing layer is the lower layer structure in the light-absorbing structure, and a light-harvesting concave lens is a regular hexagon with triangular ga...

Embodiment 11-19

[0182] The invention provides an anti-environmental light laser TV screen, which comprises a diffusion layer, a filter layer, a prism layer and a reflection layer sequentially from top to bottom. The diffusion layer consists of a light scattering layer and a substrate layer. The optical functional area in the light scattering layer that sufficiently scatters the incoming light is divided into two types, one is the micron-sized particle area, and the other is the concave-convex surface of the light scattering layer. The particle size range of the micron-sized particles is 1-50 μm. The thickness range of the diffusion layer is 75-300 μm. The light-scattering layer includes two-component polyurethane system glue and micron-sized particles, and the raw materials of the light-scattering layer include 20-80 parts of monomer 1, 10-60 parts of monomer 2, and 1 in parts by weight. - 20 parts of curing agent, 0.1-5 parts of catalyst, and 10-50 parts of micron-sized particles. The fil...

Abstract

The invention relates to the field of laser televisions, in particular to a laser television screen, and particularly relates to an ambient light resistant laser television screen and a preparation method thereof. In order to solve the problem that an existing laser television screen is low in ambient light shielding rate, the invention provides the anti-ambient light laser television screen and the preparation method thereof. The screen sequentially comprises a diffusion layer, a light filtering layer, a prism layer and a reflecting layer from top to bottom, wherein the light filtering layer comprises a nanometer rectangular square light transmitting area and a nanometer spherical light absorbing area; the nanometer rectangular square light-transmitting area is the lower layer of the light filtering layer, and the nanometer sphere light absorption area is arranged in the rectangular square light-transmitting area and above the nanometer rectangular square light-transmitting area. The ambient light shielding rate of the laser television screen provided by the invention reaches 93% or above.

Description

technical field [0001] The invention relates to the field of laser televisions, in particular to a laser television screen, in particular to an anti-environmental light laser television screen and a preparation method thereof. Background technique [0002] Laser TV is a projection display device that uses laser light as a display light source, is equipped with a special optical screen and audio equipment, and can receive broadcast TV programs or Internet TV programs. [0003] The laser has a high intensity, which can meet the needs of high-brightness display systems. The laser has extremely good directionality, and can achieve high resolution in scanning display systems. The laser spectrum is a line spectrum, and the color resolution is high. , high color saturation. The laser light source has three characteristics: high brightness, good directionality, and good monochromaticity. It is the basis for realizing high-fidelity image reproduction when used for display. [0004]...
