Laser television focusing method and device, electronic equipment and terminal

Abstract

The embodiment of the invention relates to the technical field of televisions, and discloses a laser television focusing method and device, electronic equipment and a terminal. The laser television focusing method is applied to a laser television and comprises the steps of obtaining adjustment indication information sent by an image collection device, and determining the adjustment indication information by the image collection device according to collected image definition displayed on a curtain; and adjusting the focusing distance between the laser television lens and the curtain according to the adjustment indication information, so that the laser television lens is focused on a picture. According to the embodiment, the focusing distance between the laser light source and the curtain can be quickly and accurately adjusted by the laser television, and the display effect of the laser television is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of television, and in particular to a laser television focusing method, device, electronic equipment and terminal. Background technique [0002] Laser TV is a projection display device that uses a laser light source as a display light source and cooperates with front projection display technology for imaging. It is equipped with a special projection screen and can receive broadcast TV programs or Internet TV programs. Compared with the existing rear-projection TV, LCD TV, and plasma TV, laser TV projectors have the advantages of higher color saturation and clear picture quality. Laser TV projectors use lasers as light sources, and also have low energy consumption, long life, High contrast, wide color gamut, small size and other advantages. Therefore, it has broad development prospects. [0003] The inventors have found that there are at least the following problems in the prior ar...

Problems solved by technology

[0003] The inventors have found that there are at least the following problems in the prior art: when the current laser TV is turned on and used, it is usually necessary to manually adjust the focusing distance between the laser light source and the screen, and manual focusing requires people to try continuously based on experience; The scene is relatively fixed, but it is inevitable to move the machine in daily use, or accidentally touch the machine and cause the laser TV to change its position, then it needs to be manually refocused to see a clear picture, and the operation is complicated
