Analysis of White-field Deviation of LED Display based on Chromatographic Measurement

Abstract

With the wide use of LED display,the era for perfect display-effect has arrived.However,different LED displays may differ in performance decided by many factors,including the characteristics of LED die,process,driver IC design,RD capability of manufacturer,etc.The phenomenon of color temperature deviation on white-field LED display was studied.The chromatograph differences of three primary colors in separate style and in white-field style were analyzed with chromatographic method,and the reason for the discrepancy was explored.
