In order to avoid the damage of ultraviolet light to human body, the infrared sensor 4 is arranged on the frame 12 of the display panel 1, so that the automatic control of sterilization operation can be realized. Specifically, when the infrared sensor 4 cannot detect the target object within the preset distance, the ultraviolet light source is automatically started for disinfection; when the infrared sensor 4 detects the target object within the preset distance, the ultraviolet light source is automatically turned off, and the disinfection is stopped. The preset distance can be flexibly set according to the illumination intensity and the range of the ultraviolet light generated by the ultraviolet light source and by combining the actual working condition of the field. Taking the preset distance of 5 meters as an example, when the human body is 5 meters away from the spliced screen, the human body cannot be damaged by ultraviolet light, and at the moment, the ultraviolet light source is automatically started to normally disinfect the spliced screen; otherwise, the ultraviolet light source is automatically turned off.
