Best performance LED Display can't achieve without a good driver chip, the so-called scales separated mound, mound leave the scales, led display screen driver chip is not good, so it is hard to achieve the perfect display.
In China, chip technology is still relatively lacking before, many LED chips need to be imported. LED display will have the advantages of high energy saving with driver LED CHIP, long life and environmental protection. These superiorities will be widely accepted by the users. Therefore, the importance of the driver chip for the LED Display Screen is conceivable.
How to choose a good driver led chip for a manufacturer of LED display screens ? LED display advantages Will be fully reflected with good driver IC matching.
1. The nominal input voltage range of the driver led chip should meet the DC 8~40V to meet a wide range of application needs.
2. The nominal output current requirement of the driver led chip is greater than 1.2~1.5A.
3. The output current of the driver led chip must be kept constant, so that the LED display can be stably illuminated without flickering.
4. The ability of the driver led chip is to resist EMI, noise and high voltage which is also related to whether the entire LED display product can pass CE, UL and other certifications. Therefore, when designing the driver led chip, it is necessary to select advanced topology and high-pressure production process.
5. The power consumption requirement of the driver led chip is less than 0.5W, and the switching operating frequency requirement is greater than 120Hz, so as to avoid visible flicker caused by power frequency interference.
6. The package of the driver led chip should be beneficial to drive the rapid dissipation. The physical heat dissipation structure of led chip is also very important.
The LED display must have the support of the driver led chip, and LED display cannot be separated from the driver led chip. Therefore, it needs a multi-function LED display light source to drive the IC. However, China led chip manufacturers needs to improve the led chip technology. To develop innovative design, it needs to be in the led chip. Technically, there are higher requirements and more difficulties to develop. Only in this way can LED display occupy the position in the market and produce more LED products that make customers satisfied. The LED display industry can do better and longer. .
Shenzhen YGHQ focuses on LED CHIP, LED CHIPS, LED LAMP, LED LAMPS, LED PACKAGE.
