Abstract

The embodiment of the invention provides an OLED display panel, a preparation method thereof and an OLED display device. The OLED display panel comprises a special-shaped cutting area and a display area, the display area is arranged around the special-shaped cutting area, and the display area comprises an effective display area, a first packaging area and a second packaging area, and the first packaging area and the second packaging area are located between the effective display area and the special-shaped cutting area; wherein a stress buffer component is arranged in a concave corner at the undercut in the second packaging area; through arranging the stress buffer components in the concave corners at the undercut positions, stress in the concave corners is eliminated, breakage in the undercut positions is avoided, and the technical problem that an existing OLED display panel fails due to the fact that the concave corners at the undercut positions are prone to breakage is solved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an OLED display panel, a manufacturing method thereof, and an OLED display device. Background technique [0002] OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display device is widely used in various fields due to its light weight, wide viewing angle, fast response, low temperature resistance, high luminous efficiency, and the ability to prepare curved flexible displays. In order to increase the screen-to-body ratio, the display device will design special-shaped openings, but the existing special-shaped openings are set on the edge of the display area, causing the under-screen camera, infrared sensor, earpiece and other modules to be restricted to the special-shaped openings, which affects the screen. The flexibility of setting modules such as the camera, infrared sensor, and earpiece. [0003] In order to solve the above-mentioned problems in the ...
