The difference between domestic and imported raw materials for LED display screens

There is usually a price difference between LED display screens, LED electronic display screens, LED full-color display screens, LED unit boards, etc. depending on the brand and the raw materials used. But ultimately, the main reason for the price difference of LED display screens still needs to be analyzed from the different choices of raw materials for LED display screens. Generally, LED display screen raw materials can be classified into imported materials and domestically produced materials.

In terms of luminescent chips, the sources of entry include the United States, Japan, Taiwan, and now there are also some domestically produced chips. Each type of light-emitting chip has its own advantages and disadvantages. The cost of chips from the United States and Japan remains high due to their continuous focus on key technologies, especially in similar scenarios.

Compared to the cost of self-made chips in Taiwan, there is still a certain gap in their performance compared to chips from the United States and Japan.

If the LED display screen is used in urgent situations, it is recommended to use the material of the entrance for better performance; In addition to LED large screen chips, the other urgent factor that affects the cost of LED display screens is the LED driver IC. However, if I were a customer, I would rather choose a better driver IC than a stronger one. Although it may be more expensive, the driver IC is a very urgent factor that affects the quality and lifespan of LES display screens. When making full-color LED display screens, constant voltage and constant current driver ICs must be used. Other materials such as power supplies, enclosures, and various accessories for making display screens.
