1. An organic light emitting display panel, comprising:
an array substrate, comprising a display area and a frame area surrounding the display area, wherein a plurality of organic light emitting display (OLED) pixel units are disposed in the display area of the array substrate;
a color filter substrate, comprising a display area and a frame area surrounding the display area, wherein the array substrate and the color filter substrate are disposed opposite to each other; and
an encapsulation structure, comprising at least one of a sealing frame and a sealing layer disposed between the array substrate and the color filter substrate;
wherein the sealing frame is formed by curing a frame sealant and is located in the frame area of the array substrate and the color filter substrate, and the sealing layer is formed by curing a filling adhesive and is located in the display area of the array substrate and the color filter substrate,
wherein the frame area of the array substrate comprises a first transition area, an edge defining area, a second transition area and a dicing area in sequence in a direction away from the display area of the color filter substrate or the array substrate, wherein the frame area of the array substrate further comprises a frame sealing area, the frame sealing area is located between the second transition area and the dicing area, and the sealing frame is disposed in the frame sealing area; and
a thin film encapsulation layer is disposed on the plurality of OLED pixel units, the thin film encapsulation layer extends to the frame area of the array substrate, and an edge of the thin film encapsulation layer is consistent with an outer edge of the second transition area.
