What are the forms of LED luminescent materials used in display screens?

LED light-emitting lamp (or single lamp) It is generally composed of a single LED chip, reflector, metal anode, and metal cathode, and is covered with an epoxy resin shell with light-transmitting and light-concentrating ability. One or more (different colors) single lamps can be used to form a basic pixel. Due to the high brightness, it is mostly used for outdoor display screens.
LED dot matrix module The light-emitting matrix is composed of a number of chips, which is encapsulated in a plastic case with epoxy resin. It is suitable for row and column scanning drive, easy to form a high-density display, and is mostly used for indoor display.
SMD LED light-emitting lamp (or SMD LED) is the package of the LED light-emitting lamp in the form of soldering, which can be used for indoor full-color display screens, which can realize single-point maintenance and effectively overcome the mosaic phenomenon.
