Several important reasons affecting the price of LED display
With the increasingly wide application of LED display screens, various LED display screen manufacturers have sprung up like mushrooms, and the prices of LED display screens produced are also different. Some LED display screen manufacturers sometimes have a large price difference. In fact, people who are familiar with the LED display industry know that many factors affect the price of LED displays. Now I will explain the main factors that affect the price of LED displays from the following three aspects:
1. Raw material IC chip
First of all, in terms of light-emitting chips, they can be divided into imported materials and domestic materials. Each light-emitting chip is different and has its own advantages and disadvantages. American and Japanese chips, because they have always mastered the core technology, under the background of similar monopoly, the prices of American and Japanese chips remain high. Chip prices in Taiwan and the mainland are relatively cheap, but there is still a certain gap in performance compared with chips from the United States and Japan. If the LED display is used in more important occasions, we still recommend using imported materials; in addition to the LED chip, the main factor affecting the price of the LED display is the LED driver IC, but if I am a customer, I would rather choose to compare A good driver IC, because although its price is a bit higher, the driver IC is a very important factor affecting the quality and life of the LED display. When making a full-color LED display, you must use a constant voltage and constant current driver IC; other aspects Materials such as power supplies, cabinets, and various accessories for making displays.
2. Product specifications
Our products here refer to conventional products. In terms of color, LED displays can be divided into single-color, double-color, and full-color. According to the control or use method, they can be divided into synchronous and asynchronous. From the use environment, they can be divided into indoor, outdoor and semi-outdoor. , the price of LED screens of each specification is different. Indoor full-color is divided into surface-mounted full-color, surface-mounted three-in-one full-color, and dot-matrix full-color. Outdoor full-color is divided into 1R1G1B (generally high-density , such as: PH10, PH12), 2R1G1B (generally high density, such as PH16, PH20, etc.). The configuration required for different specifications is also different, so the price will also be different.
3. Main supporting systems
