Abstract

The invention discloses an organic light emitting display panel and a driving method. Located in the same row, and the pixel driving circuits of the same color sub-pixels are connected to the same light emission control signal line; located in the same row, and the pixel driving circuits of the same color sub-pixels are connected to the same reset control signal line; The pixel drive circuit is connected to different light emission control signal lines; and the pixel drive circuits of different color sub-pixels in the same row of pixel units are connected to different reset control signal lines; During at least part of the time period of the light-emitting phase, the anodes of the light-emitting elements of the other color sub-pixels of the pixel unit in the row are reset voltages; i is a positive integer, and the present invention can avoid crosstalk problems caused by leakage currents between sub-pixels of different colors .

Description

technical field [0001] The present invention relates to display technology, in particular to an organic light emitting display panel and a driving method. Background technique [0002] In recent years, organic light-emitting display panels have gradually become the mainstream on mobile display terminal screens and medium and large-sized display screens. An organic light emitting display panel includes a plurality of sub-pixels arranged in an array. Each sub-pixel includes a pixel driving circuit and a light emitting element electrically connected to the pixel driving circuit. [0003] In the prior art, each light emitting element includes an anode, a hole auxiliary transport layer, a light emitting layer, an electron auxiliary transport layer and a cathode which are stacked. In order to increase the sub-pixel density or prepare a smaller-sized display panel, the hole-assisted transport layer, light-emitting layer, and electron-assisted transport layer of light-emitting ele...
