Laser TV with focusing device, and focusing method thereof

Abstract

The invention relates to a laser TV with a focusing device, and a focusing method thereof. The laser TV comprises a laser light source projector and projection curtain, the projection curtain is detachably connected with a four-axle positioning structure, wherein the four-axle positioning structure comprises four positioning units, four positioning elastic ropes and four detection elements; four positioning units are respectively an left upper positioning unit, a right upper positioning unit, a left lower positioning unit, and a right lower positioning unit; four positioning units are respectively and detachably connected to four corners of the projection curtain; four positioning elastic ropes comprise an upper positioning elastic rope, a lower positioning elastic rope, a left positioningelastic rope and a right positioning elastic rope. A user can directly and automatically mount and regulate the laser TV, the operation is simple and convenient, and the security convenience is greatly improved; and meanwhile, the mounting precision is guaranteed, and the mounting effect is improved.

Description

technical field [0001] The invention relates to smart home equipment, and more specifically, to a laser TV with a focusing device and a focusing method thereof. Background technique [0002] Laser TV is composed of a laser light source projector and a projection screen using reflective ultra-short-focus projection technology, and can display a good picture even in a high-brightness environment. [0003] External laser TVs are generally equipped with intelligent systems, and the hardware inside is basically the hardware used by smart TVs. The Android system cooperates with some Mstar chips to realize functions such as online playback of blockbuster movies, and can also play games, download applications, and so on. Laser TV (LASERTV) 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 three-color laser scanning images through TV signals....

AI Technical Summary

Problems solved by technology

[0004] However, the existing laser TV calibration and focusing device is very complicated. Since the laser TV is projected obliquely upward, the installer will debug after installing the projection screen. It is completely projected on the projection screen, but there is a problem in this way. Due to the complexity of projection, if the position of the projection screen needs to be adjusted or the laser light source projector needs to be adjusted in the case of home use, the projection will be offset. However, it is very difficult for users to restore the projection without technical support. Therefore, laser TVs currently on the market generally have restrictions that cannot be moved, and it is very inconvenient to use. Therefore, a laser TV that is easy to operate and can accurately focus is needed.
