Abstract

The invention discloses an organic light-emitting display panel and a driving method thereof and an organic light-emitting display device. The organic light-emitting display panel comprises multiple data lines and a driving circuit; multiple pixel units are correspondingly connected with the data lines; the driving circuit comprises multiple first multi-path selectors and multiple second multi-path selectors, the first multi-path selectors are electrically connected with the data lines, and the second multi-path selectors are electrically connected with the data lines; the organic light-emitting display panel comprises a data signal writing phase and a light emitting phase in a frame period; in the data signal writing phase, the first multi-path selectors transmit data signals to the data lines one by one, and in the light emitting phase, the pixel units emit light; the second multi-path selectors transmit first voltage signals to the data lines one by one after each data line receives the data signal and before the pixel units emit the light; the voltage values of the first voltage signals are smaller than those of the data signals. By means of the organic light-emitting display panel and the driving method thereof and the organic light-emitting display device, the uniformity of display brightness of the organic light-emitting display can be improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to the field of organic light-emitting display technology, and in particular to an organic light-emitting display panel, a driving method thereof, and an organic light-emitting display device. Background technique [0002] Organic light-emitting displays use the self-luminous properties of organic semiconductor materials for display. Compared with liquid crystal displays, organic light-emitting displays do not require backlights, which can effectively reduce the thickness of the display screen. Generally, a pixel array composed of sub-pixels is arranged in a display area of ​​an organic light emitting display. Each sub-pixel contains an organic light-emitting diode, which is driven to emit light by a pixel driver circuit. [0003] An existing type of pixel driving circuit may include a switching transistor and a driving transistor. The switching transistor is turned on u...
