Title:
ORGANIC LIGHT-EMITTING DISPLAY SCREEN AND MANUFACTURING METHOD THEREFOR, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/019803
Kind Code:
A1
Abstract:
Disclosed are an organic light-emitting display screen and a manufacturing method therefor, and a display device. The organic light-emitting display screen comprises a pixel isolation column located in a display zone, with the pixel isolation column being provided with a buffer cavity. According to the organic light-emitting display screen using the technical solution of the present application, since the buffer cavity is provided inside the pixel isolation column, when the film layer position where the buffer cavity is located is impacted by a heavy object, the buffer cavity blocks the path along which stress is further transferred downwards, such that the stress has a greater tendency to be dispersed, avoiding the destruction of a functional layer under the pixel isolation column due to stress concentration, thereby avoiding display failure. Furthermore, a manufacturing method for the organic light-emitting display screen and a display device comprising the organic light-emitting display screen are further disclosed.
