We investigated the influences of average luminance level (ALL) of display image, screen illuminance, and viewers age on the preferred luminance of LCDs. The 20 young subjects (mean age: 21.8) and 24 old subjects (mean age: 68.9) adjusted the luminance of the 17-inch 1000:1 LCD monitor to preferred level under different experimental conditions. The results indicate that the preferred luminance of the peak white (Lp) was described as following formula: Lp = k × ALL^α . Where k is a constant, ALL is an average luminance level of display image, and α is a constant 0.19-0.20 for aged users and 0.14-0.17 for young users. Influences of viewers age and screen illuminance on the luminance requirements for LCDs were discussed. These results are applicable to luminance control system for LCDs. |
