The display with density above P2 generally uses 1515, 2020, and 3528 lights, and the LED Screen parts adopts J or L package. Side welding pins, the welding area will be reflective, the ink effect is poor, it is necessary to add a mask to improve the contrast. The density is further increased, and the L or J package cannot meet the application requirements. A QFN package must be used. The characteristics of this process are no lateral welding pins and no reflection in the welding area, which makes the color rendering effect very good. In addition, the all-black integrated design is LED used for compression molding, and the screen contrast has been increased by 50%.
