    摘要: A pixel circuit (20) and a method therefor, and an organic light-emitting display. The pixel circuit (20) initializes an anode of an organic light-emitting diode (OLED) by means of a first thin-film transistor (M1), a second thin-film transistor (M2) and a seventh thin-film transistor (M7), and initializes a gate and a drain of a sixth thin-film transistor (M6) serving as a driving element by means of the first thin-film transistor (M1), a third thin-film transistor (M3) and the seventh thin-film transistor (M7) so that the service life of the OLED and the service life of the sixth thin-film transistor (M6) are prolonged. The current output by the sixth thin-film transistor (M6) serving as a driving element is irrelevant to the threshold voltage of the sixth thin-film transistor (M6) and the impedance of the power wiring, and thus uneven brightness caused by deviation of the threshold voltage of the thin-film transistor and different impedances of the power wiring can be avoided. Therefore, for the organic light-emitting display that adopts the pixel circuit (20) and the driving method therefor, the service life is prolonged and the display quality is improved.

    摘要: Provided are a pixel structure and an organic light-emitting display using same. The pixel structure comprises multiple pixels, each pixel comprises multiple sub-pixels, at least one pixel forms a pixel unit, pixel units that are longitudinally adjacent are arranged in a vertical mirror manner, and/or pixel units that are horizontally adjacent are arranged in a horizontal mirror manner. Through a reasoned structure of pixel arrangement and by deposition of sub-pixels of adjacent pixels through a shared mask aperture, the area of mask apertures can be increased during deposition, the difficulty of manufacture with the mask technique is reduced and the difficulty of the deposition process is also reduced. No gap needs to be reserved when the sub-pixels of the adjacent pixels of the mask are deposited, and genuinely high PPI can be achieved while maintaining a high aperture ratio. In addition, mask strength is increased, thus preventing deformation during use, improving product yield, increasing service life and reducing costs.

    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.
