Embodiment Construction

[0044] The present application will be described in further detail below through specific embodiments in conjunction with the accompanying drawings.

[0045] The transistors in this application may be bipolar transistors or field effect transistors. When the transistor is a bipolar transistor, the control pole refers to the base of the bipolar transistor, the first pole refers to the collector or emitter of the bipolar transistor, and the corresponding second pole refers to the emitter or collector of the bipolar transistor ; When the transistor is a field effect transistor, the control pole refers to the gate of the field effect transistor, the first pole can be the drain or source of the field effect transistor, and the corresponding second pole can be the source or drain of the field effect transistor pole. Usually in an N-type transistor, the voltage at the drain should be greater than or equal to the voltage at the source, so the position of the source-drain will vary wi...

Abstract

The invention discloses an integrated gate driving circuit, an AMOLED pixel circuit and a panel. The integrated gate driving circuit comprises a plurality of stages of cascaded gate driving unit circuits, wherein each gate driving unit circuit comprises an input part, a shifting register driving part, a light-emitting control signal generating part, a first resetting part and a second resetting part. The integrated gate driving circuit can provide various kinds of control signals, simplifies the AMOLED pixel circuit, the panel and the driving circuit thereof through time division multiplexing of a device.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an integrated gate drive circuit, an AMOLED pixel circuit and an AMOLED panel. Background technique [0002] In recent years, active organic light emitting display (AMOLED, Active matrix organic light emitting diode) technology has developed rapidly. Compared with traditional thin film transistor liquid crystal displays (TFT-LCDs), AMOLED displays have higher contrast, lower power consumption, more vivid colors and thinner display modules. Although it is generally believed that AMOLED technology has the potential to become a mainstream flat-panel display technology, its mass production has not been realized so far, and its technical bottleneck lies in the immature driving technology of AMOLED. [0003] Different from TFT-LCD, AMOLED is based on the principle of current drive, and its luminous brightness is proportional to the driving current flowing. The AMOLED pixel...
