本研究对不同环境照明强度、色温及色标亮度条件下荧光屏(CRT)16种显示色的绝对辨色效果进行了比较。结果表明,随照明强度增加,辨色效果下降,2800K色温照明下的辨色效果优于1800K、5800K色温照明,高亮度色标有利于提高辨色效果。根据实验结果可得到不同照明条件下的CRT显示颜色编码系统,且提高CRT显示色亮度可扩大颜色编码范围。
In this study, the absolute color discrimination effects of 16 kinds of display colors of fluorescent screen (CRT) under different ambient illumination intensity, color temperature and color intensity were compared. The results show that with the increase of illumination intensity, the effect of color discrimination decreases. Under 2800K color temperature illumination, the color discrimination effect is better than 1800K, 5800K color temperature illumination and high brightness color scale are helpful to improve the color discrimination effect. According to the experimental results can be obtained under different lighting conditions CRT display color coding system, and to improve CRT display color brightness can be expanded color coding range.
