移动终端显示屏呈色性能的评价

目的对主流品牌的移动终端显示屏进行呈色性能评价。方法在分析目前移动终端用途的基础上,找出各用途对应的标准,并根据标准要求对6台中高端移动终端进行呈色性能评价。评价指标包括亮度、亮度均匀性、对比度、对比度均匀性和色域覆盖率。结果 6台移动终端中有5台满足一般用途要求,只有1台能满足屏幕打样要求;部分移动终端显示屏的呈色性能达到或超过专业显示器。结论目前主流品牌的中高端移动终端大部分符合国内通信行业推荐标准规定的移动终端显示屏呈色性能要求,个别达到屏幕打样国际标准适用于移动终端的部分要求。

Evaluation on Displays of Mobile Terminals

Objective To evaluate the display performance of mobile terminals of major brands. Methods Evaluation experiments were done on six mobile terminals and one professional display on the base of standards in terms of their application. The evaluation indexes included luminance, luminance uniformity, contrast, contrast uniformity and gamut coverage rate. Results The experiments showed that five mobile terminals met the requirements of common application and only one met the requirements of color proofing. On the other hand, it showed that some mobile terminals surpassed the professional displays in terms of color performance. Conclusion It was concluded that most mobile terminals met the requirements of common application and only very few met the requirements of color proofing.
