AMOLED display device and driving method thereof

A driving method of an active matrix organic light-emitting diode (AMOLED) display device, which comprises:

• Step 1:
• providing an AMOLED display device, the AMOLED display device having a driving circuit and a display panel connected to the driving circuit;
• the display panel comprising a plurality of sub-pixels arranged in an array, and the sub-pixels further comprising red sub-pixels, green sub-pixels, blue sub-pixels, and white sub-pixels;
• and
• the driving circuit inputting Gamma control signals, and outputting a red Gamma voltage curve, a green Gamma voltage curve, a blue Gamma voltage curve, and a white Gamma voltage curve;
• Step 2:
• based on different arrangement of the sub-pixels in the display panel, different Gamma control signal is inputted to the driving circuit;
• and
• Step 3:
• based on different Gamma control signals inputted to the driving circuit, the driving circuit outputting corresponding Gamma curves to drive the display panel to accomplish displaying;
• wherein the Gamma control signals comprise at least a first Gamma control signal and a second Gamma control signal that are different from each other and respectively control the driving circuit to output the red Gamma voltage curve, the green Gamma voltage curve, the blue Gamma voltage curve, and the white Gamma voltage curve to the red, green, blue, and white sub-pixels of a first arrangement pattern and a second arrangement pattern, respectively, wherein the first arrangement pattern of the red, green, blue, and white sub-pixels is different from the second arrangement pattern of the red, green, blue, and white sub-pixels;
• and
• wherein the first Gamma control signal controls the driving circuit to output a first group of selected ones of the red, green, blue, and white Gamma voltage curves to each of two adjacent rows of the array of sub-pixels;
• and the second Gamma control signal controls the driving circuit to output a second group of selected ones of the red, green, blue, and white Gamma voltage curves to a first one of two adjacent rows of the array and to output a third group of selected ones of the red, green, blue, and white Gamma voltage curves to a second one of the two adjacent rows of the array, the second group of selected ones of the red, green, blue, and white Gamma voltage curves being different from the third group, the first group being different from both the second and third groups.
