The led luminescent materials applied to the display screen have the following forms:
( 1 ) led light emitting lamp ( or single lamp ) generally consists of a single led chip, reflective cup, metal anode, metal cathode, coated with light-transmitting light gathering ability of epoxy resin shell. One or more single lamps ( of different colors ) can be used to form a basic pixel, which is mostly used for outdoor display screens due to high brightness.
( 2 ) that led lattice module consist of a plurality of wafers to form a light emit matrix, and the led lattice module is packaged in a plastic shell by using epoxy resin. Suitable for row and column scanning drive, easy to form a high-density display screen, mostly used for indoor display screen.
( 3 ) chip led light ( or SMD led ) is the led light in the form of paste welding package, can be used for indoor full-color display screen, can realize single point maintenance, effectively overcome the mosaic phenomenon.
