Abstract

The application 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 a pixel array, multiple pixel driving circuits, multiple reference voltage signal lines, and multiple data voltage signal lines. The multiple pixel driving circuits include a first pixel driving circuit, a second pixel driving circuit and a third pixel driving circuit, wherein the first pixel driving circuit and the second pixel driving circuit are adjacent to each other along the row direction of the pixel array, and the second pixel driving circuit and the third pixel driving circuit are adjacent to each other along the row direction of the pixel array. The first pixel driving circuit and the second pixel driving circuit share one reference voltage signal line. The second pixel driving circuit and the third pixel driving circuit share one data voltage signal line. According to the scheme of the application, the number of the data voltage signal lines and the number of the reference voltage signal lines in the organic light-emitting display panel are reduced, and the organic light-emitting display panel can achieve high PPI easily.

Description

technical field [0001] The present disclosure generally relates to the field of display technologies, and in particular, relates to an organic light emitting display panel, a driving method thereof, and an organic light emitting display device. Background technique [0002] With the continuous development of display technology, the sizes and specifications of displays are changing with each passing day. In order to meet the portability of electronic devices, the demand for smaller display screens continues to grow. [0003] At the same time, users have also put forward higher requirements for the display quality of the display screen. For example, users tend to prefer high PPI (Pixel per Inch, pixels per inch) display screens to improve display accuracy and coherence. [0004] OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode, Organic Light-Emitting Diode) displays are more and more widely used in various portable electronic devices because of their features...
