    摘要： A driving method for a display panel is provided. The display panel includes a plurality of pixel circuits arranged in an array. Each of the pixel circuits respectively includes a first switch and a second switch coupled in series. The driving method for the display panel includes following steps. Plural first pulse signals are periodically received in a de-stress mode through a control terminal of the first switch of each of the pixel circuits, where the first pulse signals include a first pulse width. Plural second pulse signals are sequentially and periodically received in the de-stress mode through a control terminal of the second switch of each of the pixel circuits, where the second pulse signals include a second pulse width, and each of the pixel circuits receives the first pulse signals and the second pulse signals at different times.

    摘要： A pixel includes a pixel circuit and an organic light emitting diode. The pixel circuit has first, second, third, and fourth transistors. The first transistor controls an amount of current flowing from a first driving power supply coupled to a first node to a second driving power supply through the organic light emitting diode. The turns on when a scan signal is supplied to a first scan line. The third transistor turns on when a scan signal is supplied to a second scan line. The fourth transistor turns on when a scan signal is supplied to a third scan line. The first transistor is a p-type Low Temperature Poly-Silicon thin film transistor and the third transistor and the fourth transistor are n-type oxide semiconductor thin film transistors.

    摘要： Disclosed herein are an OLED display panel (410) further including a switching transistor (T-SW) for controlling application of supply voltage (VDD_EL) in the initializing interval of a pixel (P), an OLED display device including the same, and a method for driving the same. The OLED display panel (410) avoids a short-circuit between supply voltage VDD_EL and reference voltage Vref to thereby reduce initialization voltage applied to the gate terminal of the driving transistor T_dr. The OLED display device can achieve various effects such as improved response characteristics of pixels by reducing deviation in the initial voltage used in sampling.

The method includes repeating an operation cycle defining a frame period for a pixel circuit, including at each frame period, programming the pixel circuit (12), driving the pixel circuit (14), and relaxing a stress effect on the pixel circuit (16), prior to a next frame period. The system includes a pixel array including a plurality of pixel circuits and a plurality of lines for operation of the plurality of pixel circuits. Each of the pixel circuits (20) includes a light emitting device (22), a storage capacitor (28), and a drive circuit (24) connected to the light emitting device and the storage capacitor. The system includes a drive for operating the plurality of lines to repeat an operation cycle having a frame period so that each of the operation cycle comprises a programming cycle, a driving cycle and a relaxing cycle for relaxing a stress on a pixel circuit, prior to a next frame period.
