Abstract: A pixel structure, an Organic Light-Emitting Diode (OLED) display device, and a driving method. The pixel structure includes a number of pixel units arranged in a matrix form. Each pixel unit includes two pixel subunits adjacently arranged along a first direction and includes three sub-pixels having different colors. The two pixel subunits constitute two pixels adjacently arranged along the second direction. A distance between centers of two sub-pixels having a same color in two pixels not adjacent in three consecutive pixels in the second direction is 2 or 2N/(N+1) times of a distance between the centers of two sub-pixels having the same color in two adjacent pixels in the first direction. N is an integer greater than or equal to 1.

Abstract: 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.
