The key role played by chips in small-pitch LED displays

The LED screen is packaged with tens of thousands of lamp beads, including driver chips, PCB boards, resistors, capacitors, module kits and cabinets, etc. forming a high-definition LED display. The quality of the chip directly affects the quality, stability and performance of the entire screen. So, what is a fine-pitch LED display? What is the specific role of small-pitch LED display chips?

Reduce the dead light rate:

The dead light rate standard of traditional LED screens is usually defined as one in 10,000, while the number of lamp beads in small-pitch LED displays may be as high as millions or even billions. Considering the resolution density requirements, the dead light rate control of small-pitch LED displays is more stringent, usually requiring one in 100,000 or even one in a million. At this time, the quality of LED chips becomes particularly important.

Evaluation criteria for LED chips include electrostatic discharge and reverse leakage current. Electrostatic discharge requires that the chip not be damaged under electrostatic shock, and the smaller the reverse leakage current, the higher the reliability and the longer the service life. High-standard LED chips can ensure long-term stable operation of the screen. Here are 4 common sense about LED display chips.

Increase refresh rate:

Due to the close viewing distance of small-pitch LED displays, higher refresh rate requirements are required to avoid abnormal displays such as water ripples during shooting. The refresh rate is closely related to the driver chip. Therefore, a high refresh rate requires the LED chip to have faster response time, highly consistent capacitance and precise off time to ensure the high refresh performance of the display.

Low brightness and high gray:

In order to avoid visual fatigue caused by small-pitch LED displays when viewed at close range, LED chips need to have low brightness and high grayscale characteristics. High-performance LED chips can maintain high gray levels under low brightness conditions, not only providing a comfortable viewing experience but also maintaining image quality without loss. Do you know the specifications of LED display screen?

Under low current operation, the brightness and wavelength of the RGB three-color chip need to maintain good consistency. When adjusting the operating current, the brightness and wavelength change characteristics of the RGB three-color chip are required to be consistent to avoid problems such as screen blur and ensure the picture quality. Aesthetics. To sum up, high-performance driver chips play a vital role in small-pitch LED displays. It can not only effectively reduce the dead light rate and increase the refresh rate, but also achieve low brightness and high gray characteristics, providing the screen with higher definition image quality and more stable performance. Through strict requirements on LED chips, small-pitch LED displays can perform well in close viewing environments, allowing the audience to obtain better viewing effects.
