Abstract: The present invention provides a drive system of an AMOLED display and a method. The comparison module (4) is used to compare the first frame of image and a second frame of image in the two adjacent frames of image to be similar or not, and to determine that the second frame of image is a dynamic image or a static image, and to output time count (cnt). The gray scale control module (5) controls output gray scales of corresponding pixels in the second frame of image according the time count (cnt) and the gray scales of respective pixels in the first frame of image: when the second frame of image is the dynamic image, the gray scale control module (5) controls the output gray scales of corresponding pixels in the second frame of image remain to be original gray scales; when the second frame of image is the static image, the gray scale control module (5) controls the output gray scales of corresponding pixels in the second frame of image gradually decrease along with increase of the time count (cnt) in a specific time counting duration, to make a display brightness of the static image slowly decrease. The display effect is not influenced and the lifetime of the AMOLED display is also raised.

Abstract: The present invention discloses a display panel and the driving method thereof. It divides the pixel electrodes of the display panel into multiple groups according to the light color allowed passing through. That is, each said pixel electrode allows the light with the same color to pass through; during one frame display, the data driver applies independent Gamma voltage to each said pixel electrode. After the gate driver drives the gate line connected with a group of the pixel electrodes, it drives the gate line connected with next group of the pixel electrodes in sequence, so that it can independently adjust the Gamma voltage applied to the pixels with different colors.
