Comparison of traditional indoor LED display solutions

Indoor LED full-color display screen is composed of different kinds of unit boards, different unit boards are composed of different costs and different playback effects.

Dot matrix module system
The first design developed on the indoor imitation color dot matrix screen
Advantages: the most favorable cost of raw materials, simple production and processing technology, stable quality.
Disadvantages: poor color consistency, serious mosaic, unable to display correctly.

Single Lamp Solution
In order to solve the color problem of dot-matrix screen, one of the outdoor display technologies to transplant the outdoor pixel reuse technology (pixel sharing technology, virtual pixel technology) to indoor LED full-color display screen.
Advantages: Higher color consistency compared with dot matrix module.
Disadvantages: bad dithering effect, small viewing angle, and color difference when viewed horizontally. Complex processing, high anti-static requirements. Actual pixel resolution is more difficult than 10,000 dots.

Scenario of using face sheet light-emitting tubes as display components.
Advantages: Important display metrics such as color consistency and viewing angle are the best among the existing scenarios, especially the 3 to 1 patch mixing effect.
Cons: The processing is cumbersome and too costly.

Sub-Form Program
It is actually an improvement of the single-light program and is still under improvement.
Advantages: color consistency, viewing angle and other major indicators and bidding methods are not much different, but the cost is low, the display is good, and the resolution can theoretically reach more than 17200.
Disadvantages: processing is still complex, high anti-static requirements.
