There are many varieties of LED display screens, the price war is gradually spreading, and the competition is becoming increasingly fierce, and the prices of indoor LED display screens are different from each manufacturer. In fact, anyone who knows the LED electronic display screen industry knows that there are many factors that restrict the cost of the LED display screen: such as the specifications of the display screen, supporting factors of the material system and construction factors, all of which are determinants of the price. Why do these factors affect the cost of the display screen?

1. The impact of specifications on the screen cost of LED fluorescent lamp power supply

Here I only talk about the products of general rules. In terms of color, LED display screens can be divided into single color, dual color, and full color. In terms of utilization, they can be divided into indoor, outdoor and semi-outdoor. The price of LED screens of each specification is different. Yes, indoor full color is divided into surface mount full color, surface mount three-in-one full color, dot matrix full color, outdoor full color is divided into 1R1G1B (usually high-density, such as: PH10, PH12), 2R1G1B (the same Usually high density, such as PH16, PH20, etc.).

Second, the impact of materials on the cost of the LED display screen

The materials are divided into major categories, which can be divided into imported materials and domestic materials.

In terms of light-emitting chips, the sources of imports are: the United States, Japan, Taiwan, and now there are some domestically-made chips. 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 LED display screen is used in a more urgent situation, we still recommend using the quality of the entrance to be better; in addition to the large LED screen chip, the other emergency factor that affects the price of the LED display screen is the LED driver IC, but if I am For customers, I would rather choose a better driver IC, because it is a bit more expensive, but the driver IC is a very urgent factor that affects the quality and life of the LES display screen. The time to make a full-color LED display screen must be constant voltage. Constant current driver IC; other materials such as power supply, cabinet, and various accessories for making the display screen.
