Abstract

The invention provides a laser TV that can automatically adjust the projection size and orientation, comprising a laser projection box and a projection screen; The horizontal adjustment mechanism that makes the projection lens move horizontally in the direction parallel to the projection screen, the lifting platform fixed on the horizontal adjustment mechanism for adjusting the height of the projection lens, the angular displacement sensor for detecting the tilt angle of the projection lens, and the angular displacement sensor A connected micro-control unit; the micro-control unit respectively controls the movement of the horizontal adjustment mechanism and the lifting platform to adjust the orientation of the projection lens. The invention solves the problem that the laser TV is inconvenient to adjust the projection orientation.

Description

technical field [0001] The invention relates to the technical field of laser televisions, in particular to a laser television that can automatically adjust projection size and orientation. Background technique [0002] Compared with LCD TVs, laser TVs have the advantages of large screens, light resistance, and no eye damage, bringing users an immersive viewing experience; compared with projection equipment, they have higher definition and can be used in strong light conditions. use, and the required installation distance is smaller when adjusting the same screen size. According to relevant data, the sales volume of laser TVs in the TV market is growing rapidly, especially laser TVs above 80 inches. During the installation process of laser TV, it is necessary to manually move the position of the projection lens or the projection screen to accurately project the picture into the area of ​​the projection screen. The process of moving the projection screen and the projection sc...
