Abstract

The invention discloses an organic light emitting display device and a driving method thereof. The organic light emitting display device comprises a plurality of pixels, a data driver and a pre-charging circuit, wherein the plurality of pixels comprise a plurality of organic light emitting diodes, and a plurality of driving transistors used for supplying driving currents to the organic light emitting diodes; the data driver is used for transmitting corresponding data signals to the plurality of pixels by means of a plurality of data lines; the pre-charging circuit is used for pre-charging a voltage signal reserved at a previous timing sequence to an initial voltage, and the initial voltage is less than or equal to the minimum voltage of the data signals; and the pre-charging circuit acts before the data driver transmit the corresponding data signals to the plurality of pixels, so as to pre-charge the voltage signals reserved at the previous timing sequence by the plurality of pixels to be less than or equal to the minimum voltage of the data signals. The organic light emitting display device and the driving method thereof have the effects of being simple in timing sequence design, and reducing the power consumption of the data driver.

Description

technical field [0001] The present invention relates to an organic light emitting diode (OLED) display device and a driving method thereof, in particular to an organic light emitting display device and a driving method thereof which simplify driving sequence. Background technique [0002] Various flat panel display devices capable of reducing disadvantages of cathode ray tubes (CRTs) such as heavy weight and large size have been recently developed. Such flat panel display devices include liquid crystal displays (LCDs), field emission displays (FEDs), plasma display panels (PDPs), and organic light emitting diode (OLED) displays. [0003] Among the above-mentioned flat panel displays, OLED displays that use organic light-emitting diodes to emit light through the recombination of electrons and holes to display images have a fast response speed, are driven with low power consumption, and have excellent luminous efficiency, brightness, and viewing angle, making them become the ...
