Problems solved by technology

At the same time, due to the close distance between the chips of adjacent pixels, the light emitted by LEDs will affect each other when displaying, and the cross-light phenomenon is obvious, resulting in poor screen clarity and a great impact on the display effect

Abstract

The invention discloses an LED display module and a manufacturing method thereof, and an LED display screen and a manufacturing method thereof. The LED display module comprises a PCB, a plurality of groups of LEDs, an isolated gate, and a packaging layer, wherein the plurality of groups of LEDs are positioned on the first surface of the PCB and are electrically connected with the PCB, and each group of LED chips form a pixel point; the isolated gate is positioned on the first surface of the PCB, and each pixel point is separated by the isolated gate; and the packaging layer is positioned on the first surface of the PCB and covers each LED. According to the LED display module, all the pixel points are separated through the isolated gate structure, the problem of crosstalk between the adjacent pixel points is solved, and therefore the display effect is improved.

Description

technical field [0001] The present invention relates to the field of semiconductor packaging, more specifically, to an LED display module and a manufacturing method, an LED display screen and a manufacturing method. Background technique [0002] In recent years, LED (Light-Emitting Diode) displays are developing toward high resolution, which makes more and more pixels per unit area. However, the traditional SMD (Surface Mounted Devices) LED devices are used to assemble LED display screens by SMD, so they cannot meet the current high-resolution display requirements. Specifically, when the device is smaller, the packaging difficulty of a single chip device increases, and the corresponding cost increases; and as the number of patches increases geometrically, the assembly efficiency decreases; when the spacing between LEDs is smaller, especially when the dot pitch When the thickness is less than 800um, the difficulty of the placement process becomes more and more difficult, and...
