① LED flash (or light) usually consists of a single LED chips, reflective glass, with metal anodes, metal cathode composition, outsourcing has a light transmission light gathering ability of the epoxy resin shell. Available for one or more (different color) single lamp forms a basic pixel, due to the high brightness, used for outdoor display.
② LED dot matrix module consists of several chip light matrix, packaged in a plastic case with epoxy resin. For scan driver, high density display for easier composition, used for indoor display.
③ SMD LED light lamp (or SMD LED) is LED flash stick welding package and can be used for indoor full color display, you can achieve a single point of maintenance, overcome the mosaic appearance.
