[0002] With the development of display technology, the requirements for dot pitch are getting higher and higher. Today's LED display screens have achieved further reduction of the dot pitch distance through virtual pixel technology, reducing the dot pitch by half. However, this technology is currently only used in COB packaged LEDs. Due to the packaging characteristics of COB, this type of display screen is only suitable for indoor use, and the module thrust is insufficient, which makes it easy to knock off the lamp beads, and the cost performance is not high. Utility Model Content

[0003] In order to solve the technical problems of "light dropping" and poor air tightness of a virtual pixel LED display screen, the utility model proposes a virtual pixel TOP four-in-one structure in which sub-pixels are arranged at equal intervals to reduce the dot pitch while enhancing the thrust of the lamp beads and improving the air tightness. The purpose is to achieve an LED display screen with enhanced thrust and air tightness by improving the hardware structure of the TOP four-in-one or improving the combined connection of hardware modules and / or circuits.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a virtual pixel TOP four-in-one structure, including a bracket, the bracket is a square structure, a plurality of bowls and cups are arranged on the bracket, the bowls and cups are square structures, and the bowls and cups are placed on the front of the bracket;

[0005] Virtual pixels are arranged in the bowl;

[0006] The virtual pixel includes a plurality of sub-pixels, and each of the sub-pixels is arranged at an equal distance;

[0007] A cross waterproof groove is provided between the two bowls and cups;

[0008] The bracket is also provided with a plastic platform and a glue injection hole;

[0009] The plastic platform is placed at the bottom of the bowl cup, and a plurality of welding pads and a stretching structure are arranged between the bottom of the bowl cup and the plastic platform;

[0010] The soldering pad is located at a corner of the bowl, and a soldering pad is also provided at a corner of the bowl close to the center point of the bracket;

[0011] The virtual pixel is fixed on the pad by face-up or flip-up mounting;

[0012] Each of the pads is electrically connected to a bent pin.

[0013] Furthermore, the bowls and cups are distributed in a matrix.

[0014] Furthermore, the bent pins are arranged on both sides of the bracket.

[0015] Furthermore, the sub-pixels include R pixels, G1 pixels, G2 pixels and B pixels.

[0016] Furthermore, the sub-pixels include an R1 pixel, an R2 pixel, a G pixel and a B pixel.

[0017] Furthermore, the bracket is provided with a mark point.

[0018] Furthermore, the plurality of bowls and cups are symmetrical about a vertical mid-plane of the bracket.

[0019] Furthermore, the plurality of bowls and cups are symmetrical about a horizontal median plane of the support.

[0020] Furthermore, the plurality of bowls and cups are symmetrical about a diagonal plane of the bracket.

[0021] The beneficial effects of the present invention compared with the prior art are as follows:

[0022] 1. The utility model ensures that the sub-pixels are arranged at equal intervals through the "circular + oblique triangle" pad structure design, which increases the operable space for solid crystal and ensures the wire bonding space. If the sub-pixels are flip-chip mounted, there is also room for adjustment;

[0023] 2. The utility model can achieve a dot pitch of half the dot pitch of existing products through the arrangement and combination of several sub-pixels of the three colors of RGB. For example, for the 2020 product, the actual pixel pitch of the 2.10*2.10mm size arrangement is P2.5. The display resolution can achieve a sub-pixel effect of P1.25 through the arrangement and combination of sub-pixels;

[0024] 3. The bent pin structure of the utility model enhances the thrust of the virtual pixel with small pitch, effectively reduces the "light drop" rate, improves the air tightness of the LED display, and expands the application range of the LED display. BRIEF DESCRIPTION OF THE DRAWINGS
