| 摘要: |
| 对iPhone 4S 手机屏幕的时间均匀性、空间均匀性、色域覆盖率、色品恒定性、通道独立性等显色特性进行了测试,定量描述了iPhone 4S 的显色特性,并分析了iPhone 4S 的显色性能对显示彩色图片的影响以及如何在使用过程中达到最佳的显色性能,为用户使用提供依据。测试结果表明,iPhone 4S 的显色稳定性较好,但色域较小,在显示饱和度高的颜色时准确度不够,在使用过程中调节到中高亮度范围时,其显色性能较好。 |

| Abstract: |
| Time stability, uniformity, color gamut, chromaticity constancy, and channel independence of iPhone 4S were tested. The color characteristics of iPhone 4S were described quantitatively. The impact of color characteristics of iPhone 4S on displaying color image and the way to get the best color performance was analyzed. The results showed that iPhone 4S has good chromaticity constancy, but the color gamut is low; the accuracy in displaying high saturated color is not enough; better color performance can be acquired when adjusting to medium or high luminance range. |
