SEMI D56 - Test Method for Measurement for Ambient Contrast of Liquid Crystal Displays
Customers usually use liquid crystal displays (LCDs) in a bright environment; such as office, living room, etc. To evaluate the contrast of display devices under ambient light is more practical than in a dark environment. The results of ambient contrast measurements are affected by different illuminance, view angles, etc. Therefore, it is necessary to standardize the measurement method of ambient contrast in LCDs.
This Standard is applicable to ambient contrast measurement for LCDs.
