摘要Aiming at the problem of luminance uniformity for injection electroluminescent display panels, we present a new scan method for display panels according to successive scans theory. First, on the basis of the number of pixels requiring light emitting in one frame period, we adjust the scan time for each row. Secondly, for ensuring image transmission synchronization, the frame period must to be a constant. We adopt a 64×32 LED display panel as an example to expound the new scan method and we obtain the good result that the reduce amplitude of luminance non-uniformity is 31.34% and the increase amplitude of the average luminance value is 7.8258%.
