LED Display Chrome Calibration

Applications   On-site Calibration: Advertisement Display on the building、stadium led display、Stage rental screen、cinema led display; Factory Calibration: warehouse、production line for led modules、cabinet、whole screen;             System Hardware Features    High quality imaging device 16bits interlaced CCD, with refrigeration, high stability, high sensitivity. Point by point color measurement The use of precision matching CIE-X, Y, Z color filter, each LED lamp color coordinates accurately show, measurement accuracy of + 0.003; CIE1931 in line with the value of the stimulus value of color measurement, national standard calibration. Luminance measurement by point For small spacing LED display and large size LED display can accurately measure the brightness of each lamp data, measurement accuracy + 2.5%；     High stability Even if applied to single box correction or batch calibration still maintain high acquisition accuracy, short-term stability of + 0.5%, long-term stability of + + 1%. Higher correction Speed  CCD maximum resolution of 12 million pixels, using a full screen point acquisition mode, a single acquisition range of up to 120 thousand pixels, a single acquisition time of only about 9 seconds.   Open And Compatible Supported popular controllers including Linsn/Colorlight/Nova and so on; Provide the control protocol and service of customization;     Complex field screen correction technique Can achieve the acquisition area coordinates correction, brightness data correction and other functions; For arc screen, special-shaped screen, corner screen, tree wire shield screen still has a perfect correction program.
