1. Single lamp scheme: In order to deal with the problem of dot matrix screen color, a scheme based on the outdoor LED display skills is used for reference, and the outdoor pixel reuse skills are also transplanted to the indoor LED display.
Advantages: The color consistency is better than the lattice module method.
Defects: the mixing results are not satisfactory, the viewing angle is not large, and the degree of deviation is left and right, with color difference. The processing is complex, and the anti-static requirements are high. It is difficult to achieve pixel resolution above 10000 points in practice.
2. Sub surface pasting scheme: in practice, it is an improvement of the single lamp scheme, which is still in the process of perfection.
Advantages: There is little difference between the primary objectives such as display color consistency and perspective and the labeling scheme, but the cost is low, the display results are good, and the resolution can theoretically reach above 17200.
Defects: the processing is still complex, and the anti-static requirements are high.
3. Dot matrix module scheme: the earliest design scheme, developed from indoor pseudo color dot matrix screen
Advantages: The cost of raw materials is the most advantageous, and the production and processing technology is simple, with the same quality.
Defects: poor color consistency, severe mosaic scene, poor display results.
4. Chip mounting scheme: the scheme using chip mounted LED as the display element.
Advantages: color consistency, visual angle and other main display goals are the best of the existing schemes, especially the color mixing result of the three in one surface sticker is very good.
