Abstract

The embodiment of the invention provides an organic light-emitting display panel, a manufacturing method thereof, a display device and a mask. The organic light-emitting display panel comprises a plurality of organic light-emitting units. The organic light-emitting display panel is provided with a photosensitive module setting area, a display area surrounding the photosensitive module setting area and a frame area surrounding the display area, wherein the display area includes a first display area and a second display area; the organic light-emitting units share a first cathode in the first display area; the organic light-emitting units in each organic light-emitting unit group of the second display area share a second cathode, there is a first gap between the adjacent two second cathodes, and each first gap is communicated with the frame area and the photosensitive module setting area. The technical scheme in the embodiment of the invention can improve the product yield of the organic light-emitting display panel and reduce the cost of the organic light-emitting display panel under the premise of achieving a high screen-to-body ratio of the organic light-emitting display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic light-emitting display panel, a manufacturing method thereof, a display device, and a mask. Background technique [0002] With the development of display technology, more and more display panels and display devices are applied in people's daily life and work. For example, an organic light-emitting display panel has the advantages of self-illumination without a backlight source, thinness, wide viewing angle, wide color gamut, and fast response speed. [0003] At present, the light-emitting element of the organic light-emitting display panel is formed by an anode, a cathode, and a light-emitting layer and a carrier functional layer between the anode and the cathode. Usually, each film layer of the light-emitting element in the organic light-emitting display panel is prepared by vapor deposition. When evaporating each film layer of the organic light-emitting display pa...
