Abstract
This invention provides an AMOLED display device. The OLED panel comprises a plurality of subpixels. Each row of subpixels is electrically connected with one of the rows of OVSS. At least one of the subpixels located in a central area of the substrate is a detecting subpixel. While driving, a maximum value of the negative voltage of the detecting pixel is detected by the detection module, and the corresponding minimum positive voltage is obtained from the look-up table stored in the storage module according to the highest grayscale value and or the highest data signal voltage, and the maximum value of the negative voltage. Then a corresponding positive voltage to the OLED panel is generated from the voltage output module which is controlled by the control signal. This invention provides a driving method of AMOLED display device with low power consumption and high display quality.
