Abstract

The invention belongs to the technical field of television control, and particularly relates to a circuit capable of automatically adjusting television brightness and a television. In the embodiment of the invention, the circuit capable of automatically adjusting the television brightness comprises an ultrasonic wave transmitting circuit, an ultrasonic wave receiving circuit and a CPU (Central Processing Unit) processor, wherein the CPU processor calculates a distance between a user and the television through transmission and reception of ultrasonic waves, and adjusts the backlight brightness of the television according to the distance, so that eyes of the user can be protected.

Description

technical field [0001] The invention belongs to the technical field of television control, in particular to a circuit for automatically adjusting the brightness of the television and the television. Background technique [0002] At present, TV plays a very important role in home entertainment and information acquisition. Even today with the highly developed Internet, many people still cannot live without a TV. And rely on visual TV to transmit information. In real life, many people have various bad habits and wrong ways of watching TV. In many cases, without knowing it, our eyes have been damaged to varying degrees. So how to watch TV to protect your eyes? In fact, we should start from two aspects. On the one hand, choose a TV with better quality, with even screen brightness and no obvious dark areas. In order to reduce the stimulation of uneven light brightness to the eyes, on the other hand, we should start with habits and eliminate bad habits. Do not watch TV at clos...
