Abstract: A display apparatus having a display region, and a window region substantially surrounded by the display region and configured to install an accessory therein is provided. The display apparatus in the display region includes a plurality of display functional layers, the plurality of display functional layers comprising a display substrate. The display apparatus in the window region includes an optical clear adhesive layer at least partially occupying an accessory hole in the window region; and the accessory on a side of the optical clear adhesive layer away from a cover glass. The display substrate is completely absent in the accessory hole. The display apparatus is absent of any air layer between the optical clear adhesive layer and the cover glass.

Abstract: The present disclosure relates to a display panel, a display device, and a method for manufacturing a display panel. The display panel includes a display area, an aperture area, and an inner non-display area between the display area and the aperture area. The display area is arranged with an electroluminescent device. The electroluminescent device includes a common layer extending to the inner non-display area. The inner non-display area is arranged with a partition bar at least partially surrounding the aperture area. The common layer located in the inner non-display area is partitioned by the partition bar.

Abstract: The present disclosure provides a method for preparing a display panel, a display panel and a display device including the same. The method includes: providing a transparent substrate; and preparing a display structure and a protective film layer covering the display structure on the transparent substrate, in which the preparing the display structure includes: forming a pixel unit array and a lead metal layer on the transparent substrate; and forming a laser barrier layer on a surface of the lead metal layer away from the transparent substrate, in which an orthogonal projection of the laser barrier layer on the transparent substrate partially covers that of the lead metal layer on the transparent substrate.

Abstract: Disclosed is a display substrate including a base substrate, and a power signal line and an electrode block that are disposed on the base substrate, the electrode block covering at least one side of the power signal line. The base substrate has an encapsulation area. An orthographic projection of the power signal line on the base substrate extends out of the encapsulation area from an interior of the encapsulation area, and an orthographic projection of the electrode block on the base substrate overlaps the encapsulation area. By covering a side of the power signal line in the encapsulation area with the electrode block, the present disclosure can prevent the side of the power signal line covered with the electrode block from being drill-etched, thereby improving the encapsulation reliability of the display substrate.

Abstract: An OLED display panel, a display apparatus having the OLED display panel, and a method of manufacturing an OLED display panel are disclosed. The OLED display panel includes: a substrate; a pixel defining layer disposed on the substrate and defining a pixel region and a non-pixel region outside the pixel region; a spacer layer disposed in the non-pixel region defined by the pixel defining layer; and an organic light-emitting layer including: a first portion disposed in the pixel region defined by the pixel defining layer, and a second portion disposed in the non-pixel region defined by the pixel defining layer. A surface of at least one of the pixel defining layer or the spacer layer has a contact portion which is in contact with the organic light-emitting layer and which is rough.
