Abstract: A display device includes a pixel array. The pixel array includes multiple pixel elements. At least one pixel element includes an OLED, a first transistor, a second transistor, a third transistor, a first capacitor and a second capacitor. The first transistor has a first terminal coupled to an anode of the OLED for driving the OLED. The second transistor is coupled between a second terminal of the first transistor and a reset voltage and has a control terminal receiving a reset signal. The third transistor is coupled between the anode of the OLED and a control terminal of the first transistor and has a control terminal receiving a compensation signal. The first capacitor is coupled between the control terminal of the first transistor and the anode of the OLED. The second capacitor is coupled to the first capacitor and the control terminal of the first transistor.

Abstract: This invention is related to a pixel driving circuit and a method of driving an active matrix OLED (AMOLED) that is driven by N-type transistors. The pixel driving circuit is configured with five thin film transistors and two capacitors for solving the shifted threshold voltage induced by attenuation of the N-type transistors, the rising cross voltage induced by a long working period of the OLED, and the IR-drop issue. The invention further improves the display quality of the OLED display unit by modifying the display uniformity.
