Limiting method for watching TV at close distance, and TV set

Abstract

The method thereof comprises: an infrared human body detection module is used to detect the area in front of a TV set in order to decide if there is a person in the area; if there is a person detected in the area, the detection module starts a time keeping; if before the ending of the time keeping the person has not yet left the area, the brightness of TV set is gradually reduced and until to a lowest brightness value; when the detection module detects the person has left the area, it recovers the brightness of TV screen. The apparatus thereof comprises an infrared human body detection module, a CPU, a memory, a backlight source of display screen. The detection signal of infrared human body detection module controls the brightness of display screen through the CPU.

Description

technical field [0001] The invention relates to the technical field of televisions, in particular to a method for restricting watching television at a close distance and a television device implementing the method. Background technique [0002] Along with the development of science and technology, multimedia technologies such as TV have been widely used in millions of households. Today, with more and more TV programs, TV sets have become an indispensable household appliance for ordinary people. Television can not only help users spend their leisure time, but also bring them rich knowledge at the same time. Due to the lack of self-awareness to protect eyesight, many children have developed the bad habit of watching TV at close range. Childhood is a critical period for visual development. Watching TV at close range for a long time can easily cause myopia, which will have an irreparable impact on lifelong visual health. [0003] The adverse effect of watching TV at close ran...

AI Technical Summary

Problems solved by technology

[0005] 1. If the user only watches at close range for a short period of time, then the above technical solution will cut off the TV signal or turn off the TV against the user's will; if the user often walks around in front of the TV, then the above technical solution will cause The repeated turning on and off of the TV screen affects the normal viewing of the user, which is not humane enough

Frequent switching on and off of the TV will also affect the life of the TV

[0006] 2. Single function, once installed, it is difficult for users to change

For example, the response time of the system, the voice warning function and the switch of the vision protection function are determined by the hardware parameters, which are difficult for users to set and are not humanized enough.

[0007] 3. The hardware structure is complex and the implementation cost is high
