Description

technical field

[0001] The invention relates to SMD LED (Surface Mounted Devices, surface mount device) packaging technology, in particular to an integrated RGB LED display screen. Background technique

[0002] With the continuous development of the display industry, LEDs for display screens have changed from the original DIP (dual inline-pinpackage) structure to the SMD structure at a high speed. The advantages of installation, large luminous angle, uniform color, and reduced attenuation are more and more accepted by people. Although general SMD LEDs have the above advantages, they still have large attenuation, long heat conduction paths, low carrying current, complex production, and low reliability. Low moisture resistance and poor weather resistance; if the reliability of the product is to be improved without changing the overall structure of the product, there is still no good solution in the industry so far.

[0003] The existing small-pitch LED displays mainly use 212...
