LED digital display: a stable, of course, the SBC brand LED display. LED display 7-segment digital tube, suitable for production of the clock screen, Lee Full Color LED Display (14) rate screen to display the digital electronic display. LED dot matrix graphic display: The display device is composed of many evenly light-emitting diodes composed of dot matrix display module, suitable for broadcast text, image information. LED video display: the display is composed of many light-emitting diodes can display video, animation and other video files. By the use of the occasion indoor display: small luminous point, the general Φ 3mm - Φ 8mm, the display area is generally a few dozen square meters. Semi-outdoor screen: the pixel size in between the indoor and outdoor display; common on the lintel of the banks, shopping centers or hospitals. Outdoor display: the general area of tens of meters to several hundred square meters, high brightness, in the sun, with the wind, rain, water resistant.
A. Dot matrix module program: the earliest design, indoor pseudo-color dot matrix screen evolved advantage: the most advantageous raw material costs, and production process is simple, stable quality. Disadvantages: color consistency, the mosaic phenomenon is more serious, show less effective.
Two. Single lamp program: In order to solve the problem of lattice screen color, drawing on a program of outdoor display technology, while outdoor pixel multiplexing (also known as pixel sharing technology, the virtual pixel technology) and transplanted to the indoor display. Advantages: color consistency than dot matrix module. Disadvantages: poor mixing effect, the perspective is not about watching the color horizontally. Processing is more complex, anti-static requirements. The actual pixel resolution is more difficult to do more than 10000.
- Patch program: SMD LED display element program. Advantages: color consistency, perspective and other important indicators are the best of the existing programs, especially the triple paste mixing effect is very good. Disadvantages: trouble processing technology, the cost is too high.
- Asia paste the program: in fact, an improved single-lamp program, is still perfect.Advantages: color consistency, perspectives, and the primary indicators and labeling program is not very different, but the costs are lower, the display is very good, resolution is theoretically possible to do 17200. Disadvantages: processing more complex, anti-static requirements
