specific Embodiment approach

[0035] Further, see image 3 , as a specific embodiment of the LED display screen provided by the present invention, it also includes adhesive glue 4, the adhesive glue 4 is located around and at the bottom of the LED lamp bead 22, and bonds the LED lamp bead 22 and the PCB board 21, The adhesion of the LED lamp beads 22 is increased, which can prevent the LED lamp beads 22 fixed on the PCB board 21 from becoming loose and falling off from the PCB board 21 .

[0036] Specifically, the LED lamp bead 22 on the PCB board 21 is often bumped and loosened, so the LED lamp bead 22 often falls off from the PCB board 21 and adheres to the periphery and the bottom of the LED lamp bead 22 and the PCB board 21 Adhesive 4 can effectively prevent this from happening.

[0037] Further, see figure 1 , as a specific embodiment of the LED display screen provided by the present invention, the PCB board 21 is provided with a plurality of through holes 211 , and the LED lamp beads 22 avoid the t...

Embodiment approach

[0048] Further, see figure 2 , as a specific embodiment of the LED display screen provided by the present invention, it also includes a waterproof heat conduction pad 5, the waterproof heat conduction pad 5 is arranged between the PCB board 21 and the box frame 1, and the waterproof heat conduction pad 5 is embedded in the PCB board 21 The side opposite to the control device 111 facilitates the heat dissipation of the control device 111 by utilizing the heat transfer characteristics of the waterproof heat conduction pad 5 .

Abstract

The invention provides an LED display screen, comprising a box frame and a display unit fixed in the box frame. The display unit comprises a PCB board and a plurality of LED lamp beads fixed on the PCB board. The front and back surfaces of the display unit are coated with a transparent waterproof film. The front and back surfaces of the display unit of the LED display screen provided by the invention are coated with waterproof films, which can play a waterproof role and avoid short circuit of the display unit. The waterproof film can also play the role of protecting the LED lamp beads and PCBboards, avoiding damage to the LED lamp beads and corrosion of the PCB boards; The transparent waterproof film is convenient for the light emitted by the LED lamp beads to be irradiated out through the waterproof film, so the PCB board after the LED lamp beads are installed and the waterproof film is coated can be directly fixed on the box frame, so that the PCB board can be used, and the PCB board can be directly maintained during maintenance, and the PCB board is simple and convenient.

Description

technical field [0001] The invention belongs to the technical field of LED display screens, and more specifically relates to an LED display screen. Background technique [0002] With the development of society, LED display is more and more widely used in life, and LED display has been integrated into many aspects of our life. [0003] LED display is a kind of flat-panel display, which is a device used to display information such as text, images, video and video signals. Since the LED display can be extended arbitrarily, seamless splicing can be realized, the running time is long, and interactive technology can be used to improve the display effect. Good, so it is widely used in airports, shopping malls, hotels, high-speed rail, subways, cinemas, exhibitions, office buildings and other places. [0004] The LED display generally includes a number of LED lamp beads, a PCB board and a box frame. The LED lamp beads are welded on the PCB board, and the PCB board is fixed on the b...
