摘要： The present invention provides a scanning driver and an organic light-emitting display using the same. The scanning driver comprises a plurality of cascaded structures receiving signals from a first timing clock line (CK1) and a second timing clock line (CK2) with opposite phases, the cascaded structures successively generating output signals (i.e., scanning signals), wherein each of the cascaded structures comprises: a first transistor, connected to a starting signal line or to a scanning output line of a previous cascaded structure; a second transistor, connected to the second timing clock line and to the scanning output line; a third transistor connected to a high-level power supply VGH; a fourth transistor, connected to a low-level power supply VGL and to an output terminal of the third transistor; a fifth transistor, connected to a high-level power supply VGH and to a scanning output line; and a first capacitor, connected between an output terminal of the first transistor and the scanning output line. Arranging a first capacitor C1 between the output terminal of M1 and the scanning output line prevents slight-ON of M2, thus reducing the reverse current at the scanning driver and reducing the power consumption.

摘要： A pixel circuit, a pixel, and an AMOLED (Active Matrix Organic Light-Emitting Diode) display device comprising the pixel and a driving method thereof. The pixel circuit comprises a power supply circuit, a basic circuit and a compensation circuit, which are sequentially connected. The power supply circuit is connected to a first power supply to supply power to the basis circuit. The compensation circuit is connected to second and third power supplies, respectively, for providing difference values compensating for a voltage and current of an OLED (Organic Light-Emitting Diode). The pixel comprises an OLED and the pixel circuit. The AMOLED display device comprises the pixel circuit. By compensating for a difference between threshold and power supply voltages of a transistor, the response characteristics of the AMOLED may be improved to generate light of a same brightness, thereby meeting requirements on image uniformity and consistency of an AMOLED.

摘要： A pixel circuit, a display device, and a drive method therefor. The pixel circuit comprises: a first power source (ELVDD), a second power source (ELVSS), an organic light-emitting diode (OLED), a first capacitor (C1), a first transistor (T1), a second transistor (T2), and a third transistor (T3), wherein the first transistor (T1) is configured to compensate a threshold voltage of the third transistor (T3). According to the drive method, the pixel circuit is driven to emit light by sequentially applying scanning signals to the pixel circuit on scanning lines (Sn1, Sn2, Sn3). The pixel circuit and the method for driving the pixel circuit can improve the response characteristics of active matrix organic light-emitting diodes, thereby enabling the display device to display images having uniform image quality.
