摘　　要：LED显示屏广泛应用的今天,对LED显示屏显示效果的要求日臻完美,但是,由于LED管芯的特性、工艺,驱动芯片设计以及生产厂家研发能力等因素,造成LED显示屏显示效果的差异性。对LED显示屏白场色温显示偏差这一现象进行研究,基于色谱测量,分析其中各基色单独显示和白场中显示色谱的变化,探讨产生差异的原因。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.
