led display is indeed quoted by the square, because the size is required to do according to the demand, the size of the arbitrary; and then it is the led display quotes cumbersome and different, is also a big difference.
There are two major boards that affect the led display offer, one is the system supporting, the second is the screen cost;
System supporting contains:
1, system accessories: receive/send/splicing card;
2, the playback system: control computer, playback software ...
3, monitoring series: sensors as well as monitoring software;
4, audio equipment;
5: protection system: heat dissipation design, power distribution with, temperature and humidity detection...
System accessories are mainly based on the size of the screen to choose, the number and quality need to be strictly controlled, but not all are mandatory, but the system accessories and playback system are to have, and according to the brand selection of no need, the price is also a certain discrepancy;
Screen itself cost:
led display is made of led lamp beads, and encapsulation is different, cob encapsulation price is higher than the price of the screen;
The screen itself cost:
Led display is produced by the led lamp beads, and encapsulation is also different. There are different, cob encapsulation price is higher than the same price SMD encapsulation of 10% -20%, and light-emitting chip is different, the price is also a big difference, the light-emitting chip quality on the market, light-emitting chip determines the service life of the led display, the chip quality is not pass, the product is certainly not good.
Expanded Information:
LED on the image display using the electronic light emitting system to display the results of the digital signal for the image type conversion. Dedicated video card JMC-LED came into being in the PCI bus using a 64-bit graphics gas pedal on the basis of the formation of a unified compatibility with the VGA, video functions, so that the video data superimposed on the VGA data, perfect compatibility with the shortcomings.
The use of full-screen way to capture the resolution, so that the video image can realize the full-angle resolution to strengthen the resolution effect, to put an end to the problem of fuzzy edges, can be scaled at any time and move the image arbitrarily, on different playback requirements can be timely response. Effective separation of red, green and blue, to enhance the electronic display screen playback of the true color imaging effect.
