This paper introduces a reliable and practical TV proximity protection device. The device is mainly composed of a human signal detection and processing circuit, a voice prompt circuit and a control output circuit. When a human body approaches, the TV can issue a voice prompt and cut off the TV signal; when the human body leaves the detection range, the TV signal is automatically restored after a delay. Keywords: Vision protection Infrared sensor Voice prompt
