Description

technical field [0001] The invention relates to the field of electronic information and automatic control, in particular to an intelligent dimming device and method for a television screen based on ultrasonic distance measurement. Background technique [0002] Along with the development of society, television sets have been popularized and become an important means for people to increase their knowledge and enrich their leisure life, but watching TV for a long time, especially watching TV at a close distance will cause greater damage to eyes. The data show that watching TV at close range for a long time, especially TV with high brightness, is an important cause of myopia in teenagers. Considering that teenagers generally lack self-protection awareness, they often do not pay attention to keeping a proper distance when watching TV. When watching TV at a distance, the brightness of the TV screen can be appropriately reduced, which can reduce the damage to the eyes caused by wat...
