In view of the hotter full-color LED display products in the current market, today, Shigei Guangxu Xiaobian combines his technical advantages to introduce different contrasts of different full-color LED displays:
First, the dot matrix module solution, the earliest design solution, was 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.
Second, the single-lamp solution, in order to solve the dot-screen color problem, draws on a solution of outdoor display technology, and simultaneously transplants the outdoor pixel multiplexing technology (also called pixel sharing technology, virtual pixel technology) 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.
Third, the patching scheme adopts a patch LED 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.
Fourth, the sub-surface patching scheme is actually an improvement of the single-lamp scheme and is still being improved.
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.
A solar cell panel, solar electric panel, photo-voltaic (PV) module, PV panel or solar panel is an assembly of photovoltaic solar cells mounted in a (usually rectangular) frame, and a neatly organised collection of PV panels is called a photovoltaic system or solar array. Solar panels capture sunlight as a source of radiant energy, which is converted into electric energy in the form of direct current (DC) electricity. Arrays of a photovoltaic system can be used to generate solar electricity that supplies electrical equipment directly, or feeds power back into an alternate current (AC) grid via an inverter system.
