Abstract
Improved evaluation of temporal response of a display is achieved by displaying a plurality of test patterns. The number of pixels of each test pattern driven at the first driving level is greater than the number of pixels driven at the second driving level. In addition, each pixel is driven at a first driving level in multiple consecutive test patterns (e.g., for multiple consecutive frames) such that the actual output of the pixel when driven at the first driving level matches the uncompensated “ideal” output of that pixel when driven at the first driving level. In other words, the output of the pixel driven at the first driving level would be same as the output of that pixel after having been driven at the first luminance for a time period exceeding the maximum fall time of the pixel. The pixel is then driven at the second driving level.
