1. What is led screen calibration?

The calibration of LED lights refers to ensuring that all LED modules or boards on the screen are uniform in color and brightness, displaying a uniform, high-quality image.


2. Why does the LED display have inconsistencies in brightness and color?

  • main reason:

Some customers will ask: “If I want the LED display to have the same brightness and display color and directly use the same brand of LED chips, can it be solved?”

The answer is NO~ now, maybe in the future!

First of all, we need to know that even for the same LED brand, the difference in brightness and color will be caused by the difference in production time.

Secondly, with the same brand of LED, the same production time, but different LED display module production cycles, its brightness, and display color will be different.

  • Other reasons:

– The mask color of the LED module.

– LED module driver IC.

 Flatness between LED display modules.

– The flatness before the LED display cabinet.

– The LED display has been used for a long time


3. Why is led pixel correction necessary for a led display screen?

A high-resolution display can provide a great viewing experience when your LED display is well-calibrated.

Any shading or tonal inconsistency on the screen can ruin the entire viewing experience, so calibration is a great way to avoid unbalanced colors and colors on the led screen.

When the unbalanced brightness and color lead to high power usage, the higher brightness will increase the power consumption of the LED display, which will require a lot of electricity bills and reduce the life of the LED display.
