【摘要】：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。
[Abstract]:Environmental illumination and screen brightness are two major factors that affect the performance of mobile phone display. In this paper, 14 different environmental illumination levels are selected to test the automatic adjustment function of mobile phone brightness. According to the test results, 24 groups of representative environmental illumination and mobile phone luminance combination were selected for subjective evaluation of mobile phone screen display quality. On the basis of subjective evaluation, 12 groups of environmental illumination and mobile phone brightness combination are selected to measure the display quality parameters of mobile phone screen. The optimal combination of environmental illumination and mobile phone luminance is obtained by combining the subjective evaluation results with the results of quality parameter measurement. The subjective experimental results show that the environmental illumination is invariant. The display effect of the mobile phone can be effectively improved by properly increasing the automatic adjustment brightness of the mobile phone; The measurement of display quality parameters shows that the brightness contrast of the mobile phone screen can be improved after the automatic adjustment of the luminance of the mobile phone under the condition of constant ambient illumination. The color saturation and gamut range are obviously improved.
