LED Color Calibration Introduction

Color calibration is a core technology which is used to enhance the bright uniformity and color fidelity of the LED display. Collecting each pixel (or each color sub-pixels) brightness region (and color) datas and getting the correction coefficient for each sub-matrix color or correction coefficient matrix for each pixel, the datas are fed back to the control system of the display and the system apply the result to respectively driving each pixel (or each color sub-pixel), the LED display image color gets real restore finally.

Since there are considerable differences in the variable LED lamp brightness and dominant wavelength, when the LED display used for a long time, there will be differences in different regions of the brightness and chroma  like color, Leukoplakia, Huaping  .That will cause a huge loss of commercial value for those who requires high quality of the screen. LED color calibration technology allows users to significantly enhance the brightness, color uniformity, color authenticity improvements and eliminate the gap in a short time at low cost ,significantly improve image quality, thus extending the life of the display for users to create more business value and reduce waste of resources.

Now our company  has mastered the LED display calibration technology in the worldwide and already produced mature software . The software can realise the LED display in the full-screen gamut optimization and attenuation correction brightness for the luminance and chrominance eliminate the gap between the screen by taking picture of the screen and a series of  processing analysis,. The screen color authenticity will be adjusted and presented high quality image to the users.
