Abstract: An organic light emitting display panel and an organic light emitting display apparatus are provided. The display panel includes an array substrate and a plurality of organic light emitting elements disposed on the array substrate, where the array substrate includes a substrate, and a first metal layer and a second metal layer sequentially disposed toward the plurality of organic light emitting elements; a first display area, a second display area, and a first bezel area, where, in a first direction, a number of organic light emitting elements in a row of organic light emitting elements in the first display area is smaller than a number of organic light emitting elements in a row of organic light emitting elements in the second display area, and the first bezel area is disposed adjacent to the first display area in the first direction; and a plurality of gate signal lines.

Abstract: An array substrate, a display panel and a display device are provided. The array substrate has a display area and a non-display area surrounding the display area. The array substrate includes: pixel circuits arranged in the display area in an array along a first direction and a second direction; a first gate driving circuit in the non-display area including first shift register units; and a second gate driving circuit in the non-display area including a plurality of second shift register units in cascade connection. The first gate driving circuit and the second gate driving circuit are electrically connected to different transistors in the pixel circuits; and an orthographic projection of the first gate driving circuit on a plane of the array substrate and an orthographic projection of the second gate driving circuit on the plane of the array substrate at least partially overlap along the second direction.
