Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0034] figure 1 It is a schematic diagram of the structure of the existing PPA+copper pin package bracket. Since this type of package bracket uses the injection molding machine to attach the thermoplastic material to the metal, there is no sticking together. When thermal expansion and cold contraction, it is easy to A gap is generated, and when the end customer is using it, external water and water vapor can easily enter the package through the gap, causing product failure. figure 2 It is a schematic diagram of the structure of the existing CHIP type packaging bracket. It is formed by surrounding and compacting the glass fiber with resin 801, and then dipping copper and platinum etching lines. The gap and moisture absorption rate of the...

Abstract

The present invention provides an integrated RGB-LED display. The integrated RGB-LED display comprises a PCB board and a plurality of RGB-LED package modules welded to the PCB board; the package module comprises a package holder and a plurality of light emitting units arranged on the package holder; the number of light emitting units is at least two, and each set of light emitting units comprises a set of RGB-LED chips. According to the integrated RGB-LED display provided by the present invention, a plurality of light emitting units are integrated on a package module to further improve the production efficiency and reduce the production cost; and in addition, the plurality of light emitting units are integrated on a package module, so that overall resistance of the display to external mechanical strength is improved.

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...
