First, the matrix module scheme, the earliest design scheme, developed by indoor pseudo color dot matrix screen.
Advantages: the raw material cost is the most advantage, and the production process is simple, the quality is stable.
Disadvantages: poor color consistency, serious mosaic phenomenon, poor display effect.
Second, single lamp program, in order to solve the problem of color dot matrix screen, using a scheme of outdoor display technology, and outdoor pixel multiplexing (also called pixel sharing technology, virtual pixel Technology) transplanted to the indoor display.
Advantages: color consistency is better than bitmap module.
Disadvantages: mixed color effect is not good, the angle of view is not large, the horizontal direction of the left and right to look at chromatic aberration. Processing is more complex, anti-static requirements. The actual pixel resolution is harder than 10000.
Third, the patch scheme adopts SMD LED as the display element.
Advantages: color, consistency, visual angle and other important indicators, is the best one of the existing programs, especially the "three in one" table paste color mixing effect is very good.
Disadvantages: the processing technology is troublesome and the cost is too high.
Fourth, the sub scheme is actually an improvement of the single light program, which is still in the process of improvement.
Advantages: there is little difference between the primary index and the labeling scheme in the display of color consistency and visual angle, but the cost is low, the display effect is very good, and the resolution can be more than 17200 in theory.
Disadvantages: processing is still more complex, anti-static requirements.
