Abstract: Embodiments of the present disclosure provide a display panel, a method of manufacturing the display panel, and a display apparatus with the display panel. The display panel includes: a substrate including a display area and a non-display area around the display area; at least one dam disposed in the non-display area of the substrate and having an undulated structure on a surface of the dam facing away from the substrate; and an encapsulation layer disposed on a side of the dam facing away from the substrate.

Abstract: The disclosure relates to an OLED display substrate, a manufacturing method and a display apparatus. The OLED display substrate comprises a base substrate, and a plurality of light-emitting elements and a plurality of pixel defining layers formed on the base substrate, wherein a pixel defining layer is located between any two adjacent light-emitting elements of the plurality of light-emitting elements; and a surface of the pixel defining layer facing away from the base substrate comprises an accommodating portion, a bottom surface of the accommodating portion and the surface of the pixel defining layer facing away from the base substrate are located at different planes, and an orthographic projection of the accommodating portion on the base substrate does not overlap with an orthographic projection of the plurality of light-emitting elements on the base substrate. The method for manufacturing the OLED display substrate is configured to manufacture the above OLED display substrate.

Abstract: An evaporation mask plate for a display substrate is provided. The display substrate includes a plurality of pixel units arranged in an array, and a dam is disposed in each of the pixel units. The evaporation mask plate includes a mask plate body and evaporation openings arranged on the mask plate body in an array. The evaporation openings run through the evaporation mask plate body and correspond to an area to be vapor-deposited of each pixel unit on the display substrate. The mask plate body includes a thinned region for covering the dam of the display substrate during evaporation and an active region located between the thinned region and the evaporation openings. The thickness of the thinned region is less than the thickness of the active region. An evaporation method adopting the evaporation mask plate is also provided.
