Abstract
The present application relates to the field of display technology, and provides a driving method and a driving device of display panel, and a display device, by calculating an average gray-scale value of original pixel units in each sub-region of the display panel, then judging whether the average gray-scale value is greater than a preset gray-scale threshold. If the average gray-scale value is greater than the preset gray-scale threshold, a corrected pixel voltage value of the sub-region, according to the average gray-scale value and a preset pixel voltage conversion relationship, is determined, and the corrected pixel voltage value as a pixel voltage value of original pixel units in the sub-region is set.
