Description

Technical Field

[0001] The utility model relates to the field of screens, in particular to an anti-light screen. Background Art

[0002] Laser TV is the fourth generation of television that uses laser light source and is equipped with a professional anti-glare gain screen. It can watch radio and television programs and on-demand Internet content. Television technology has gone through three technological iterations: black and white television, color television, and digital television represented by LCD TV, PDP, OLED, etc. Laser TV combines DLP digital film projection technology that uses laser light source with television technology to form the fourth generation of television display technology.

[0003] Short-throw projectors have a very short transmittance ratio, which is the ratio of the distance from the projector to the screen to the screen size. This is a major advancement in the projection field. The projector can project images onto a large screen from a few inches away from the screen surface. The situation where walking in front of the projector and blocking the image on the screen will no longer exist. With the help of ultra-short-throw projectors, bright and colorful large-screen images can be viewed in any room, classroom, and conference room.

[0004] The application of laser TVs and ultra-short-throw projectors is becoming increasingly popular, and the demand for screens is also increasing. The screens of existing laser TVs and ultra-short-throw projectors are affected by ambient light when in use and lack the effect of resisting ambient light. Therefore, when watching, the contrast is low and the color display will also be affected to a certain extent.

[0005] Therefore, it is necessary to propose an anti-glare screen to solve the above problems. Utility Model Content

[0006] The main purpose of the utility model is to provide an anti-glare screen, which can effectively solve the problems in the background technology.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] An anti-light screen comprises a substrate, one side of the substrate is provided with a micro-prism structure, the horizontal side of the micro-prism structure is provided with a light-absorbing material, and the inclined side of the micro-prism structure is provided with a reflective layer.

[0009] Preferably, the reflection layer is a reflection layer, and the reflection layer is used to reflect the light emitted by the projection device into an image.

[0010] Preferably, the material of the substrate includes but is not limited to PVC, TPU and PET materials. Beneficial Effects

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. This anti-glare screen is a flexible rollable anti-glare screen that can be used for ground-lift or electric screen scenes. The micro-prism structure is arranged on the substrate. The material of the substrate includes but is not limited to PVC, TPU and PET materials. The horizontal edge of the micro-prism structure is a light-absorbing material, and the inclined edge of the micro-prism structure is a reflective layer. When ambient light is irradiated on the micro-prism structure, the micro-prism structure will absorb the ambient light irradiated on the screen. When the image projected by the projection device is irradiated on the reflective layer of the micro-prism structure, reflective imaging processing can be performed, so that it will not be disturbed by ambient light, can resist ambient light, and provide high-contrast, colorful image effects.

The reflective layer 3 is a reflective layer, and the reflective layer 3 is used to reflect the light emitted by the projection device into an image. The material of the substrate 1 includes but is not limited to PVC, TPU and PET materials. Specific embodiments

[0018] The diagonal of the substrate 1 is denoted as S. Taking a 16:9 screen as an example, the angle of the micro-prism structure 4 is denoted as α. The height of the micro-prism structure 4 is 100um>h>2um. The angle calculation formula of the micro-prism structure 4 is: 45.02282-2866242×arctg0.050314×S+45.15558≥α≥45.02282-28.66242×argtg0.050314×S, from which the value of the angle α of the micro-prism structure 4 can be calculated.

The material of the substrate 1 includes but is not limited to PVC, TPU and PET materials. The horizontal edge of the micro-prism structure 4 is a light-absorbing material 2, and the inclined edge of the micro-prism structure 4 is a reflective layer 3. Ambient light is irradiated on the micro-prism structure 4, and the micro-prism structure 4 absorbs the ambient light irradiated on the screen. When the image projected by the projection device is irradiated on the reflective layer 3 of the micro-prism structure 4, reflective imaging processing can be performed, so that it will not be disturbed by ambient light, can resist ambient light, and provide a high-contrast, colorful image effect.
