The advantages and disadvantages of indoor LED display solutions

The advantages and disadvantages of the indoor LED display program comparison: 1. Lattice module scheme; 2. Single lamp program; 3. Patch scheme; Asian surface mount scheme.

Comparison of advantages and disadvantages of indoor LED display programs The dot matrix module scheme: The earliest design scheme, developed from indoor pseudo-color dot matrix screens, has advantages in raw material cost, simple production and processing technology, and stable quality.

Disadvantages: poor color consistency, mosaic phenomenon is more serious, poor display.

2. Single-lamp solution: To solve the color problem of dot-matrix screens, a solution for outdoor display technology is used for reference. At the same time, outdoor pixel multiplexing technology (also called pixel sharing technology, virtual pixel technology) is transplanted to indoor display screens.

Advantages: Color consistency is better than dot matrix mode.

Disadvantages: poor color mixing effect, small viewing angle, horizontal viewing of color difference. The processing is more complicated and the antistatic requirements are high. Actual pixel resolution is more than 10,000 points harder.

3. Patch scheme: Adopt the SMD LED as the display component.

Advantages: Color consistency, viewing angles and other important indicators are the best ones in the existing solutions, especially the three-in-one surface-mount color mixing effect is very good.

Disadvantages: The processing process is troublesome and the cost is too high.

4. Sub-surface sticker program: It is actually an improvement of the single lamp program and is still being improved.

Advantages: In the display of color consistency, the primary indicators such as viewing angle and labeling program are not much different, but the cost is lower, the display effect is very good, the resolution can theoretically be more than 17,200.

Disadvantages: Processing is still more complicated and anti-static requirements are high.
