The goal of our study is to clarify the realistic viewing conditions surrounding flat panel display television (FPD TV) and the relationship between preferred luminance and TV screen size, as flat panel display TV is becoming increasingly popular. We have conducted an investigation of TV viewing conditions at homes. Our study of viewing conditions indicates that the viewing distance at home is 3 times of absolute display height at minimum with an average of 2.5m and mean screen illuminance is 100-300 lx. We also have conducted an investigation of the relationship between preferred luminance and TV screen size using LCD TV. Our study indicates that the most preferred luminance depends on visual angle (screen size and viewing distance). At fixed viewing distance, the most preferred luminance depends on TV screen size. As TV screen size gets larger, the most preferred luminance becomes darker. And in home, most preferred luminance of distance 3 times of absolute display height (3H) and screen illuminance at 180 lx is approximately 240cd/m². And as the screen illuminance becomes darker, the most preferred luminance becomes darker while the most preferred luminance depends on visual angle.
