Embodiment 1

[0040] combine figure 2 and image 3 Shown, a kind of manufacturing method of arc-shaped black grating anti-light curtain for laser TV, comprises the following steps:

[0041] S1. Using UV resin or thermoplastic material as the substrate layer, using mold hot pressing to form a prism structure array with curved surface distribution;

[0042] S2. Use gravure printing equipment to print a white reflective layer on both the light-absorbing surface and the reflective surface of the prism structure;

[0043] S3. Use gravure pad printing equipment to print black light-absorbing coating on both the light-absorbing and reflective surfaces of the prism structure;

[0044] S4, using a laser to remove the black light-absorbing coating on the reflective surface;

[0045] S5. Attach the printed curtain to the supporting curtain.

[0046] Preferably, the substrate layer in step S1 is a plastic film or PET.

[0047] In the above technical solution, the black light-absorbing coating or ...

Embodiment 2

[0050] A method for manufacturing an arc-shaped black grid anti-light curtain for laser television, comprising the following steps:

[0051] S1. White plastic film is used as the base material layer, and molded by hot pressing to form a prism structure array with curved surface distribution;

[0052] S2. Use gravure pad printing equipment to print black light-absorbing coating on both the light-absorbing and reflective surfaces of the prism structure;

[0053] S3, using a laser to remove the black light-absorbing coating on the reflective surface;

[0054] S4. Attach the printed curtain to the supporting curtain.

[0055] In the above technical solution, the substrate layer in step S1 is a white plastic film. Compared with Example 1, there is no need to print a white reflective layer on the prism structure, and the white color of the white plastic film itself can achieve a reflective effect instead of white Reflective layer.

[0056] The gravure pad printing equipment used ...

Abstract

The invention relates to the technical field of anti-light curtains. The technical scheme of the invention is as follows: an arc-shaped black gate light-resistant curtain for a laser television comprises a supporting curtain, a base material layer is arranged on the supporting curtain, a plurality of prism structures are arranged on the outer surface of the base material layer to form a prism structure array, the cross section of each prism structure is triangular, the lower side face of each prism structure is a light reflecting face and provided with a white light reflecting layer, and the upper side face of each prism structure is a light absorbing face and provided with a black light absorbing coating; and the prism structures are bent in an arc shape with the midpoint of the lower long edge of the outer surface of the base material layer as the circle center, and the multiple prism structures of the prism structure array are continuously arranged in a concentric circle structure.The effect similar to that of a Fresnel light-resistant curtain is achieved in an arc-shaped black gate mode, the cost is lower than that of the Fresnel light-resistant curtain, and the display effectis good.

Description

technical field [0001] The invention relates to the field of anti-light curtains, in particular to an arc-shaped black-grid anti-light curtain for laser televisions and a manufacturing method thereof. Background technique [0002] Laser TV uses semiconductor-pumped solid-state laser working material to generate continuous laser light with three wavelengths of red, green and blue as the light source of color laser TV, and controls the three-color laser scanning image through TV signals. Its color gamut coverage can theoretically reach more than 90% of the human eye color gamut, which is a level higher than the highest 62% color gamut coverage of existing ordinary projectors. [0003] The laser TVs currently on the market are basically short-focus laser projections, which have the advantages of easy installation and do not take up space. Due to its short focal length, there is a big difference between choosing a laser TV screen and an ordinary projection screen. Laser TVs ne...
