Analysis of the technical advantages of led display
Date: 2019-11-07
Comparison of existing common indoor full color schemes:
1. Dot matrix module solution: The earliest design solution, developed from the indoor pseudo-color dot matrix screen. Advantages: The raw material cost is the most advantageous, and the production and processing technology is simple and the quality is stable. Disadvantages: poor color consistency, more serious mosaic phenomenon, poor display effect. 2. Single lamp solution: In order to solve the problem of dot matrix color, a solution of outdoor display technology is used, and outdoor pixel multiplexing technology (also called pixel sharing technology, virtual pixel technology) is transplanted to the indoor display. Advantages: Color consistency is better than dot matrix module. Disadvantages: The color mixing effect is not good, the viewing angle is not large, and there is color difference in the horizontal direction. The processing is more complicated and the antistatic requirement is high. It is more difficult to achieve an actual pixel resolution of 10,000 points or more. 3. Patch scheme: A patch LED is used as a display component. Advantages: Color consistency, viewing angle and other important display indicators are the best in the existing program, especially the three-in-one surface sticker color mixing effect is very good. Disadvantages: The processing process is cumbersome and the cost is too high. 4. Sub-surface patching scheme: Actually, it is an improvement of the single-lamp scheme, and it is still in the process of improvement. Advantages: There is little difference between the display of color consistency, viewing angle and other primary indicators and labeling schemes, but the cost is lower, the display effect is very good, and the resolution can theoretically achieve more than 17200. Disadvantages: Processing is more complicated and antistatic requirements are high.
