环境照度和手机屏幕亮度是影响手机显示性能的两大影响因素。本文选取14个不同的环境照度水平对手机的亮度自动调节功能进行测试，根据测试结果选取24组有代表性的环境照度和手机亮度组合进行手机屏幕显示质量主观评测，在主观评测的基础上选取12组环境照度和手机亮度组合对手机屏幕的显示质量参数进行测量，并综合主观评测结果与质量参数测量结果分析得到最优的环境照度与手机亮度组合。主观实验结果表明：在环境照度不变的情况下，适当地提高手机的自动调节亮度能有效改善手机的显示效果；不同环境照度下的手机亮度最优值不同。显示质量参数测量实验表明：在环境照度不变的情况下，适当地提高手机的自动调节亮度后手机屏幕的亮度对比度、色彩饱和度及色域范围均有明显提升。

Environmental illumination and mobile phone screen brightness is the two major factors which influence the effects of mobile phone display performance.This paper tests the function of brightness automatic adjustment of three different mobile phones under 14 environmental illumination levels and designs a subjective experiment of image quality assessment under 24 different environmen-tal illumination and mobile phone luminance combination.And the paper measures the display quality parameters under 12 different environmental illumination and mobile phone luminance combination on the basis of subjective experiment.The subjective experiment results show that the rise of mobile phone brightness can improve the display effect of mobile phone,and the optimal mobile phone bright-ness is changing under different environmental illumination values.The test experiment results show that the rise of mobile phone brightness can improve the luminance contrast,color saturation and color gamut range of mobile phone.
