How to Deal with Uneven Chromaticity on a Rolling LED Screen?

When using the rolling LED screen, sometimes the color unevenness problem may occur due to various reasons. The appearance of uneven chromaticity can cause color deviation in the display, affecting the overall image quality, which in turn impacts the display effect and the viewer's experience. So do you know what to do if the rolling LED screen has uneven chromaticity? Here, ONUMEN will introduce:

When the rolling LED screen has uneven chromaticity, the following measures can be taken:

Calibrate the screen: Use professional calibration equipment to calibrate the rolling LED screen to ensure it meets expectations under different colors and brightness levels.

Inspect the LED beads: First, check if the rolling LED screen has damaged or severely aged LED beads. These beads might cause uneven chromaticity. If damaged or aged beads are found, they should be replaced promptly, ensuring the new beads match the original ones in chromaticity and brightness.

Inspect the optical system: Check the rolling LED screen for its optical system, such as lenses and reflectors, ensuring they are not damaged or contaminated. If necessary, clean or replace them to ensure uniform light propagation.

Optimize thermal design: LED beads may exhibit chromaticity shift under high temperatures. Ensure that the rolling LED screen's cooling system is functioning correctly to reduce the temperature rise of LED beads. We can improve cooling efficiency by adding cooling devices such as fans and heat sinks.

Adjust the driving current: An over- or under-sized driving current can lead to uneven chromaticity in the LED beads. Therefore, the driving current of the rolling LED screen can be adjusted appropriately to find the suitable chromaticity performance.

Use brightness correction technology: The brightness correction technology can make separate brightness adjustments for each pixel or pixel group to improve chromaticity issues. We can achieve brightness correction through software or hardware to ensure the consistency of the rolling LED screen's chromaticity.

In summary, these are the relevant measures for handling uneven chromaticity issues in the rolling LED screen. If the above methods cannot solve the chromaticity issue, it is recommended to contact professional rolling LED screen manufacturers like ONUMEN to seek expert help and advice.
