Problems solved by technology

[0008] However, since the small beam emitted by the infrared emitter propagates along a straight line, the human eye protection area is smaller when there are fewer infrared emitters
In order to increase the coverage of the infrared rays emitted by the infrared emitter, some existing products use multiple infrared emitters to achieve the purpose of improving the detection range, which will make the structure more complicated and increase the cost of the product

Abstract

The invention discloses a laser TV which can detect a movable or immovable object close to the laser TV rapidly and accurately to finish human eye protection actions and is relatively low in cost. Thelaser TV comprises a host shell and a lens arranged on the host shell; a light guide pipe is arranged at the circumference of the lens; the light guide pipe is provided with an opening along the extension direction; an infrared emitter is arranged inside the light guide pipe; the light guide pipe is used for reflecting the infrared rays emitted out by the infrared emitter to the whole light guidepipe in a diffuse manner and emitting out the rays from the opening; an infrared receiver is arranged at the host shell and is located at the position close to the lens; and the infrared receiver isused for receiving the infrared rays which are reflected by objects and emitted out from the opening. The laser TV is used for human eye protection.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a laser television. 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. Compared with LCD TVs, laser TVs have more vivid colors and higher brightness. Moreover, it also has inherent advantages in the manufacture of super large screens. Compared with LCD TVs of the same size, the laser light source has a longer service life and lower power consumption, which meets the needs of society for energy conservation and environmental protection. In the use of laser TVs, due to the particularity of laser products, in order to prevent accidental damage caused by strong lasers, some laser TVs are also equipped with eye protection functions. The laser TVs with human eye protection function in the prior art ...
