Abstract

The invention provides a scanning circuit, an organic light-emitting display device and a driving method of organic light-emitting display device. The scanning circuit comprises a first driving circuit, a second driving circuit, an output unit and an isolating transistor, wherein the first driving circuit is used for generating a first-stage voltage according to signals of a first input end, a second input end, a third input end and a first power supply; the second driving circuit is used for generating a second-stage voltage according to the first-stage voltage and signals of a second input end and a second power supply; the output unit is used for generating an output signal according to the first-stage voltage, the second-stage voltage, the first power supply and a signal of a third input end; and the isolating transistor is connected between the first power supply and the output unit. According to the scanning circuit, the problems that the power consumption of the organic light-emitting display device is increased due to a relatively large leak current between the first power supply and the output signal is overcome.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a scanning circuit, an organic light-emitting display device and a driving method thereof. Background technique [0002] In recent years, many types of display devices have been developed at home and abroad, such as liquid crystal display devices, plasma display devices, electrowetting display devices, electrophoretic display devices, organic light-emitting display devices, and the like. Among them, the organic light-emitting display device uses the recombination of electron-hole pairs in a specific material to emit light of a specific wavelength to display images. It has the advantages of fast response, low power consumption, thinness, and wide color gamut. One of the most concerned technologies. [0003] Such as figure 1 As shown, an organic light emitting display device generally includes a display area and a non-display area disposed around the display area. The display a...
