Abstract
The present disclosure provides an OLED array substrate, a display panel and a display device. The OLED array substrate includes a first display region and a second display region; the first display region is adjacent to the second display region, and includes first OLED pixels arranged in an array; the second display region includes second OLED pixels arranged in an array; a pixel density of the second OLED pixels is less than a pixel density of the first OLED pixels; second pixel driving units of second OLED pixels and first pixel driving units of first OLED pixels in a same row are connected to a same first-type scan line, there is at least one second-type scan line between two adjacent first-type scan lines; one second-type scan line is only connected to first pixel driving units of first OLED pixels in a same row.
