Embodiment Construction

[0018] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0019] Such as figure 1 as shown, figure 1 It is a structural schematic diagram of a pixel module of an LED display screen of the present invention. An LED display screen includes a pixel module 1, a circuit board, and a power supply. The pixel module 1 is composed of a plurality of LED monomers 2, and the LED monomer 2 is composed of a red light-emitting diode 3, a green light-emitting diode 4, The blue light-emitting diode 5 is composed of light-emitting diodes of three colors. The LED monomer 2 is welded on the front of the circuit board, and a layer of waterproof adhesive tape is provided on the side and back of the circuit board to prevent liquid from entering the LED. Inside the display screen, the circuit b...

Abstract

The invention relates to an LED display screen. The LED display screen comprises a pixel module, a circuit board and a power supply. The pixel module is composed of a plurality of LED single bodies, each LED single body is composed of a red light-emitting diode, a green light-emitting diode and a blue light-emitting diode, the LED single bodies are welded to the front side of the circuit board, and a solar power supply module is adopted as the power supply and used for supplying power to all the LED single bodies respectively through a power supply distributor. According to the LED display screen, the red light-emitting diodes, the green light-emitting diodes and the blue light-emitting diodes form the LED single bodies, then the multiple LED single bodies form the pixel module, and therefore the color of light emitted by each LED single body can be adjusted by controlling the red light-emitting diode, the green light-emitting diode and the blue light-emitting diode in the LED single body, and accordingly the display color of the LED display screen can be changed; the LED display screen is simple in structure and convenient to use; meanwhile, the solar power supply module is adopted as the power supply, and therefore energy is saved.

Description

technical field [0001] The invention relates to a display device, in particular to an LED display screen. Background technique [0002] LED is a light-emitting diode, which is a semiconductor solid light-emitting device. It uses a solid semiconductor chip as a light-emitting material. When a forward voltage is applied to both ends, the carriers in the semiconductor recombine to cause photon emission to generate light. The LED display screen is a display screen that displays various information such as text, graphics, images, animations, market prices, video, video signals, etc. by controlling the display mode of the LED and relying on the on and off of the LED. The structure and principle of the existing LED full-color display are as follows: According to the sub-requirements of the dot pitch of the LED display, the three primary color LEDs are uniformly welded on the PCB, and a constant current driver IC is used to control the current of the three color light-emitting chips...
