LED DISPLAY SCREEN AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/047619
Kind Code:
A1
Abstract:
A light-emitting diode (LED) display screen (100) and display device (200), the LED display screen (100) comprising: a frame (10) that is used for assembling a module (20) and a power supply box (30); the module (20) comprises an LED lamp board (201), and a non-display surface of the LED lamp board (21) is provided with a first socket (211) that abuts against a board-to-board connector; a bottom surface within the power supply box (30) is provided with a control card that abuts against the LED lamp board (21) by means of the board-to-board connector; the control card comprises a main control card (32) and at least one sub-control card (31), the sub-control card (31) and the main control card (32) being separated and connected by means of a cable; a surface of the sub-control card (31) facing the LED lamp board (21) is provided with a second socket (311) that cooperatively abuts against the first socket (211), and each sub-control card (31) is fixed by means of an elastic mechanism and the bottom surface of the power supply box (30) that is opposite to the lamp board (21); when a display surface of the LED lamp board (21) suffers an impact, the elastic mechanism may simultaneously move the module (20) and sub-control card (31) in a direction backward to the display surface and cause the relative position of the first socket (211) and second socket (311) to remain the same. Thus, undesirable phenomena of the LED lamp board (21), such as a black screen appearing, may be prevented when the LED lamp board (21) suffers an impact from a soccer ball and like objects.
