Method for calibrating, characterizing and driving a color flat panel display |
摘要 |
A method of calibrating a flat panel, includes the steps of:
providing a flat panel display having an overall and individual channel adjustment for both gain and offset and an adjustment to provide a white point for the display, the white point including color temperature, chromaticity and luminance level; displaying a first target using a low level code value for each channel of the display; sensing the luminance level of the displayed first target; adjusting the gain of the display so that the sensed luminance level matches a first predetermined aim value representing a luminance level at least 3 decades lower than a maximum luminance level; displaying a second target using intermediate code values for each channel of the display device; sensing the luminance level and chromaticities of the displayed second target; adjusting the individual channel offsets so that the luminance level matches a second predetermined aim value representing an intermediate luminance level and the chromaticities match a first set of predetermined chromaticities that represent a desired white point; displaying a third target using maximum code values for each channel of the display; sensing the luminance level and chromaticities of the displayed third target; adjusting the individual channel gains so that the luminance level matches a third predetermined aim value the maximum luminance level and the chromaticities match the first set of predetermined chromaticities; and repeating until no further adjustment is required. |
