In the manufacturing process, LED outdoor screen firstly encapsulates the luminous grain into a single LED, which is called a single lamp. Generally, it adopts the reflective cup with concentrated light to improve the brightness.Then, multiple LED single lights are encapsulated into pixel modules, and the display unit box is composed of pixel modules. According to user needs and the display application site, a display unit box is taken as the required size.The box body needs to be sealed in the design to achieve the purpose of waterproof and fogproof, so that it can adapt to the outdoor environment. Generally, the front side is sealed by pouring glue.
2. Indoor LED display
In the manufacturing process, LED indoor screen firstly makes the luminous grains into a lattice module, and then the lattice module is spliced into a display unit plate of a certain size. According to the user‘s requirements, the unit plate is used as the basic unit to be spliced into the required size.Indoor screen area generally from less than 1 square meter to more than 10 square meters, point density higher, in non-direct sunlight or lighting lighting environment use, viewing distance in a few meters, the screen body does not have sealing waterproof capacity.
3. Semi-outdoor LED display
Half outdoor screen is between outdoor and indoor, many of which are LED door head screen with high luminous brightness, which can be used in the outdoor with direct sunlight. The screen body is sealed to a certain extent, usually under the eaves or in the window.
