Abstract

The invention discloses an organic light-emitting display panel and a driving method thereof. The organic light-emitting display panel comprises a display region and a non-display region. The display region comprises a plurality of rows of pixel units. Each row of pixel unit comprises a plurality of pixel driving circuits. The non-display region comprises a plurality of reset signal conversion units, a plurality of stages first scanning driving circuits, a plurality of stages of second scanning driving circuits, at least one first reset voltage transmission line and at least one second reset voltage transmission line. Each reset signal conversion unit comprises a first reset signal switch and a second reset signal switch. The first reset signal switch is used for providing a first reset voltage to a pixel driving circuit, and the second reset signal switch is used for providing a second reset voltage to the pixel driving circuit, wherein the first reset voltage is larger than the second reset voltage. Each reset signal conversion unit can provide different reset voltages to a drive transistor and an organic light-emitting diode of each pixel driving circuit, thereby improving display effect.

Description

technical field [0001] The invention relates to the display field, in particular to an organic light emitting display panel and a driving method thereof. Background technique [0002] In display technology, organic light emitting diode display (Organic Light Emitting Diode, OLED) is widely used in the industry due to its thinness, active light emission, fast response speed, wide viewing angle, rich color and high brightness, low power consumption, and high and low temperature resistance. It is recognized as the third-generation display technology after Liquid Crystal Display (LCD). [0003] At present, OLED displays are mainly current-controlled light emitting, and the uniformity of light emitting is controlled by the corresponding current. However, since the threshold voltage of the drive transistor of each pixel of the OLED display tends to drift with time, the current flowing through the OLED deviates under the same data signal, resulting in uneven display brightness; at...
