Abstract

The invention relates to the technical field of television manufacturing, in particular to a laser television and a human eye protection method based on the laser television. The problems that the laser television is frequently triggered to execute human eye protection operation due to the fact that the user cannot obtain the safe distance, the protection operation means is single, and dynamic optimization cannot be carried out along with the position of the user can be solved to a certain extent. The laser television includes: a light source; a radar assembly used for monitoring the detection distance from a user to the light source; a controller configured to receive the detection distance sent by the radar assembly. When the user enters a first distance interval, a first dynamic picture used for reminding the user to be away from the light source is displayed, the first dynamic picture is increased along with a decrease in the detection distance between the user and the light source when the user moves, and the value of the detection distance is displayed on the first dynamic picture in real time; when the user continues to approach the light source, a second dynamic picture is displayed, and operation is executed according to the protection strategy information to protect human eyes.

Description

technical field [0001] The present application relates to the technical field of television manufacturing, in particular, to a laser television and a laser television-based human eye protection method. Background technique [0002] Laser TV is a fourth-generation TV that uses laser light source, is equipped with a professional anti-light gain screen, and can watch radio and television programs and order Internet content. Since the laser TV uses a laser light source with high luminous intensity, if the user accidentally looks directly at the lens of the laser projector during use, it is very easy to damage the user's eyes. [0003] In the implementation of some laser TV human eye protection, in order to avoid the accidental occurrence of light source burning the user's eyes, an infrared sensor is usually installed on the laser TV; after detecting that the user is close to the laser emission area, the laser TV will lower the overall projection brightness, In order to achieve ...
