Problems solved by technology

The heat dissipation effect of the current LED display is not ideal, because the LED lamp beads need to emit light and heat for a long time, if the heat dissipation problem is not solved well, it will directly affect the service life of the LED display
Existing LED displays usually dissipate heat through heat sinks, but the heat dissipation effect is not ideal
In addition, the LED display screen is set on one side, which is not conducive to making full use of the display space

Abstract

The invention discloses a double-sided LED display screen. The double-sided LED display screen comprises an outer frame and surface covers arranged on front and back sides of the outer frame, wherein two LED modules are arranged between the outer frame and the two surface covers; each LED module comprises a PCB (printed circuit board), LED beads are mounted on the PCB, a heat-conducting silica gel sheet is mounted on the back surface of the PCB and is equivalent to the back surface of the PCB in size, a heat-conducting plate is mounted on the inner side of the heat-conducting silica gel sheet and closely attached to the heat-conducting silica gel sheet, and multiple heat-conducting fins are arranged on the inner side surface of the heat-conducting plate. The display screen can utilize display space sufficiently for double-sided display; the heat-conducting silica gel sheets and the heat-conducting plates are arranged on the back surfaces of the double-sided display screen, the heat-conducting fins are formed on the heat-conducting plates, the double-sided LED display screen is simple in structure and has the good cooling effect, and the service life of the display screen is prolonged.

Description

technical field [0001] The invention relates to the field of LED display screens, in particular to a double-sided LED display screen. Background technique [0002] With the continuous improvement of LED display technology, LED-related products are becoming more and more abundant, and the application fields are becoming wider and wider. The heat dissipation effect of the current LED display screen is not ideal, because the LED lamp beads need to emit light and heat for a long time, if the heat dissipation problem is not solved well, it will directly affect the service life of the LED display screen. Existing LED display screens usually dissipate heat through a heat sink, but the heat dissipation effect is not ideal. In addition, the LED display screen is set on one side, which is not conducive to making full use of the display space. Contents of the invention [0003] The purpose of the present invention is to provide a double-sided LED display screen with better heat dis...
