Problems solved by technology

With the development of science and technology and economy, the market has higher and higher requirements for the clarity of the display screen, and now the mainstream LED display manufacturers adopt the chip technology to manufacture the LED display pixel pitch with a minimum pixel pitch of P5 (that is, the distance between two pixels) The center distance is 5mm, the smaller the pixel pitch, the higher the pixel density per unit area, and the higher the definition), which can no longer meet the market's requirements for high-definition LED displays

Abstract

The invention discloses a package structure and a package method for a high definition LED display screen module. The package structure for the high definition LED display screen module comprises a PCB, a plurality of pixel units, QFN circuits, capacitors and driving IC chips, wherein the pixel units are connected to the front face of the PCB and arranged in a determinant mode, the QFN circuits, the capacitors and the driving IC chips are connected to the back face of the PCB, and the central distance between every two adjacent pixel units is 1.5mm. The integral structure of the package structure meets the requirement of the market for the definition of the high definition LED display screen. The package structure is reasonable in layout and high in package precision, the packaged LED display screen module is wide in application range, and the LED display screen module can be used for large screen display of an indoor instruction dispatch system and high definition display of a film screen.

Description

technical field [0001] The invention relates to the field of LED display screens, in particular to a high-definition LED display screen module packaging structure and packaging method. Background technique [0002] LED display developed rapidly in the world in the late 1980s and became a new type of display media. It uses dot matrix pixel units composed of light-emitting diodes to form a large-area display screen. It has high reliability, long service life, strong environmental adaptability, and high cost performance. With the characteristics of low cost of use, it has rapidly grown into one of the mainstream products of flat panel display in just two decades, and has been widely used in the field of information display. With the development of science and technology and economy, the market has higher and higher requirements for the clarity of the display screen, and now the mainstream LED display manufacturers adopt the chip technology to manufacture the LED display pix...
