It is mainly used in outdoor application. To produce outdoor LED display
, the first step is to package luminous grains into unit light-emitting diode, naming single-lamp. The single-lamp used to make outdoor display generally adopts reflective cup that can concentrate light to improve the luminance of the lamp. The second step is to package many LED single-lamps into a pixel tube or pixel module. Then to compose many of them into a dot-matrix unit display cabinet. According to the customers’ requirements and the locations applied, finally, to make required outdoor LED display
with specific size from unit display cabinet. The cabinet should be sealed to guard against water and fog, enabling the display to be adaptable in outdoor environment. outdoor LED display
can be divided into the following types according to the density of their pixel: 4094, 2500, 2066, 1600, and 1024 dot.
