Problems solved by technology

[0004] Since the brightness and contrast of ordinary projection screens cannot meet the standards of home TVs, in order to achieve good brightness and good contrast, manufacturers use expensive special screens
While achieving a good display effect, it also raises the cost of laser TVs, and also prevents the popularization of laser TVs

Abstract

The invention discloses a laser television screen and a laser television system. The laser television screen comprises a backboard on which an optical film sheet is arranged, wherein, the optical film sheet has several optical modules for reflecting light projected by a laser television host to audience and absorbing ambient light, and the optical modules are transversely arranged on the optical film sheet. According to the laser television screen and the laser television system, by arranging, on the optical film sheet, the optical modules for reflecting light projected by a laser television host to audience and absorbing ambient light, an image sent by the laser television host is projected onto the laser television screen and reflected to the audience by the laser television screen, however the ambient light is absorbed by the optical modules, thus realizing that the image is improved in contrast degree while the image is improved in brightness.

Description

technical field [0001] The invention relates to the technical field of laser television, in particular to a laser television screen and a laser television system. 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 be as high as more than 90% of the human eye color gamut, which is a level higher than the highest 62% color gamut coverage of existing LED TVs. [0003] Due to the improvement of color gamut coverage, not only can the entire TV picture look more real, layered and transparent, but also the clarity of the picture will be greatly improved with the improvement of color saturation. Since the laser is used as the backlight of the TV, the laser TV can be made thinner and suitable for home use....
