LED BOX BODY FOR ANTI-PIRACY AND DISPLAY SCREEN

摘要

An LED box body for anti-piracy. The LED box body comprises an LED module (1), a middle frame (2), a rear cover (3), a video signal interface, a video receiving PCB, a first locking member (4), a second locking member (5), and a sensor (6). A closing state of the box body can be ensured by means of a locking structure formed by the first locking member (4) and the second locking member (5). The sensor (6) is connected to a video source; when the sensor (6) senses that the first locking member (4) and the second locking member (5) are locked, the sensor (6) generates an access signal, the video source transmits a video signal to the LED box body, and when the sensor (6) does not sense that the first locking member (4) and the second locking member (5) are locked, the sensor (6) generates an open circuit signal, and the video source stops transmitting the video signal. Therefore, film and television resources can be prevented from leaking from the LED box body, and the security of the film and television resources is guaranteed.
