    Pixel Calibration


    Pixel calibration technology is used to promote the brightness uniformity and color fidelity of LED display. Namely, through the brightness (and chromaticity) data acquisition of each pixel region on the LED screen (or every based sub-pixel), the correction coefficient of each based sub-pixel or the correction coefficient matrix of each pixel can be obtained. And then convey the information to the control system of the display. The control system will use the correction coefficient to realize the different drive of each pixel (or every based sub-pixel).Therefore, display pictures will be pure and smooth, and the color will be natural.
    The features of Chainzone’s Pixel Calibration

    Corrected data is saved in modules. Therefore, positions of corrected modules can be randomly interchanged.

    Pixel calibration, module calibration, cabinet calibration, whole screen calibration and onsite calibration are all possible.


    Onsite Calibration


    Support the calibration for LEDs of different batches and wavelength


    Before calibration                                                                                                             After calibration

    HD Image


    The grey level of Mage display can reach 16bit/color (grey level change between 0-65535), and the refresh frequency is >1000Hz. Wide range of grey level and high refresh frequency enable display picture to be natural and smooth.

    Stripes occur because                                                              False color shows because                                                            16bit,1000Hz make Picture
    of low refresh                                                                                    of low grey level                                                                          soft and natural          

    For human’s visual system, the feelings to brightness, or to RGB color are not linear relationship but logarithmic. Gamma Adjustment is a transmission function applied in the LED display system and it is to conquer this non-linear relationship. Generally, Gamma values between 2.2-2.5 because of the difference between visual environment and equipment characteristics.
    To achieve perfect display showing effect for both highlight and shadow tone, Chainzone’s Gamma adjustment is a dynamic one.

    Shadow tone is dim and indistinct                                                                                                   Perfect display showing effect for
