Abstract

Embodiments of the present invention provide a display panel, a driving method thereof, and a display device, which relate to the field of display technology, and can compensate fluctuations in initial power supply signals, thereby improving the reliability of light emission of sub-pixels. The display panel includes: a display area and a non-display area surrounding the display area, and a plurality of sub-pixels are arranged in the display area; a power signal bus is provided in the non-display area, and the power signal bus is electrically connected to the sub-pixels and transmits a fixed potential to the sub-pixels Signal: a filter inductance part with a filter function provided in the non-display area, and the power signal bus is electrically connected to the signal transmission pin through the filter inductance part.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a display panel, a driving method thereof, and a display device. 【Background technique】 [0002] Organic Light-Emitting Diode (OLED) display panels have been widely used due to their advantages of high brightness, low power consumption, and fast response. [0003] A plurality of sub-pixels arranged in a matrix are arranged in the display area of ​​the OLED display panel, and each sub-pixel includes a pixel circuit and a light emitting diode. The anode of the light-emitting diode receives the driving current converted from the positive power supply signal and the data signal, and the negative pole receives the negative power supply signal, and the light-emitting diode emits light under the action of the voltage difference between the positive and negative poles. It can be seen that the light-emitting state of the light-emitting diode will be affected by the power signa...
