Background

At present, LED display screens are developing towards small and even micro-spacing directions, and hundreds of thousands to millions of LEDs are often integrated on one LED display screen. However, as the pixel pitch of the LED display screen is reduced, the number of packaged devices per unit area is increased, so that the packaging difficulty is increased exponentially. The current leading technologies are to fabricate the display module (or named module) of the display screen by N-in-one (i.e. a plurality of pixels are integrated into a chip device) or COB packaging technology. The traditional lamp bead is also provided with a waterproof structure technology, but is generally used for traditional display or illumination, and does not relate to a small-space N-in-one patch packaging device. However, the N-in-one package device is generally used for indoor display screens, and is less related to outdoor display screens, and the outdoor display screens have technical requirements of water resistance, corrosion resistance and the like in a room, so that improvement of the outdoor display screens is particularly necessary.
