Problems solved by technology

However, the antistatic performance of LEDs is generally between 2KVˉ5KV, and the actual use may require antistatic properties of 10KV or higher, so existing LED screens are prone to dead pixels

Abstract

The invention provides an anti-static LED display screen and a manufacturing method thereof. The display screen comprises a PCB, a plurality of LED particles, a plastic frame and an anti-static layer, wherein the plurality of LED particles are arranged on the PCB; the plastic frame is arranged on the PCB; the plastic frame comprises a plurality of bulge parts which are arranged at intervals in the direction vertical to the PCB; the bulge parts and the PCB form a plurality of grooves; the LED particles are arranged in the plurality of grooves; and the anti-static layer covers the upper surface of the plastic frame. The anti-static LED display screen has the advantages that the anti-static layer attached to the surface of the anti-static LED display screen can play a shielding effect, increases the contrast and can avoid the damage of static electricity to the LED particles.

Description

technical field [0001] The invention relates to the field of display screens, in particular to an antistatic LED display screen and a manufacturing method thereof. Background technique [0002] The existing LED display screen is mounted on the PCB board through a single LED SMT (Surface Mount Technology, referred to as SMT), and then a black plastic frame is pasted to isolate each LED, so that each LED forms a separate imaging pixel, avoiding LEDs. The crosstalk between light rays improves the contrast. At the same time, in order to improve the contrast, black PCB and LED encapsulant with melanin are also used. The black plastic frame will absorb a lot of light, and the black PCB will also absorb a lot of light. LED particles also need to use encapsulant with melanin, which leads to The brightness of the LED display is greatly reduced, the luminous efficiency is seriously reduced, and the graininess of the display screen is very strong, and there is no integrated flat feeli...
