Led display screens are indeed quoted on a square basis, because the size needs to be made according to demand, and the size is arbitrary; then, the quotation of led display screens is cumbersome and different, and it is also very different.

There are two major sections that affect the price of led display screens, one is the system supporting, and the other is the cost of the screen;

System package includes

1. System accessories: receiving special card/sending special equipment card/video processing splicer;

2. Play system: control computer, play software, power amplifier and sound...

3. Monitoring series: sensors and monitoring software;

4. Audio equipment;

5: Protection system: heat dissipation design, power distribution matching, temperature and humidity detection...

System accessories are mainly selected according to the size of the screen. The quantity and quality need to be strictly controlled, but not all of them are mandatory options, but the system accessories and playback system are required, and they are not selected according to the brand, and the price is also certain. Go in and out

Screen body's own cost:

The led display is made of led lamp beads, and the package is also different. The price of the cob package is 10%-20% higher than that of the SMD package at the same price. And the light-emitting chip is different, the price is also very different, and there are light-emitting devices on the market. The chip quality is uneven, the light-emitting chip determines the service life of the led display, the quality of the chip is not good, and the product will definitely not be good. The failure rate in the later use process is slightly higher. my country's LED display screens are still relatively dependent on foreign technology for raw materials and core technology. Among them, the quality of LED chips is also quite different, and LED lamp beads are also a relatively important factor in price constraints. Each light-emitting chip has its own advantages and disadvantages. American and Japanese chips, because of their constant focus on technology, under similar control conditions, the price of American and Japanese chips remains high. Taiwan and local chips are relatively self-made, but there is still a certain gap in performance compared with American and Japanese chips. If the display screen is used in more important occasions, or when the customer's budget is sufficient, it is better to use imported chips; although it is a bit more expensive, the driver IC is very important to affect the quality and life of the LES screen. In addition, the price of other materials such as power supply, cabinet, and other accessories made of led display screen.
