【文章內(nèi)容簡介】 ED digital display: display 7segment digital tube, suitable for the production of the clock screen, such as interest rates screen, display digital electronic display. LED dotmatrix graphic display: display device is posed by many evenly lightemitting diode dot matrix display module, suitable for broadcast text, image information. LED video display: the display device is posed of a plurality of lightemitting diode, you can display video, animation and other video files. 3 occasions by the use of classification Indoor display: the luminous point is small, generally ? 3mm 8mm, shows the general area of a few dozen square meters. Outdoor display: the general area of tens of meters to several hundred square meters, high brightness, can work in the sun, wind, rain, water resistant. 4 light spot diameter Indoor screen: Φ3mm, , Φ5mm. Room shielding: 10mm, 12mm, 16mm, 19mm, 216。 20 mm, 21mm, Φ22mm, Φ26mm. LED display indicates that the program 1 dot matrix module program: the first design, evolved by the indoor pseudocolor dot matrix screen. Advantages: raw material costs have an advantage, and the production process is simple, stable quality. Disadvantages: poor color consistency the mosaic phenomenon is more serious, look much worse. 2 single lamp program: to solve lattice screen color problem, drawing on a program of outdoor display technology, outdoor pixel multiplexing (also known as pixel sharing technology, virtual pixel technology) transplanted to the indoor display. Advantages: good color consistency than dot matrix module way. Disadvantages: poor color mixing effect, the perspective is not about viewing color in the horizontal direction. The processing is more plex, requiring high antistatic. The actual pixel resolution is more difficult to do more than 10000. 3 patch program: SMD LED display elements of the program. Advantages: color consistency, perspective and other important display indicators are the best kind of existing programs, especially the triple paste the mixing effect is very good. Disadvantages: processing trouble, the cost is too high. Stickers program: in fact, an improvement of the single
