The OLED display includes a flat display area and an edge curved-surface display area; wherein the edge curved-surface display area is provided with an optical film layer, and the optical film layer is configured to reduce a light intensity of emergent light with a preset color in the edge curved-surface display area.

OLED display panel and OLED display device including edge curved-surface display area

An organic electroluminescence display panel, a manufacturing method, a color shift reducing method, and a display device are provided. The display panel includes a flat surface portion and a curved surface portion. The hole transport layer of the display panel includes a common hole transport layer and hole transport units. The common hole transport layer is distributed in the flat surface portion and the curved surface portion. The hole transport units are disposed on the common hole transport layer and are in one-to-one relationship with sub-pixels of the two portions; the hole transport layer of the sub-pixel of at least one color has different thickness in the two portions; and the thickness of the hole transport layer of the sub-pixel is the sum of the thickness of the common hole transport layer in sub-pixel and the thickness of the hole transport unit of the sub-pixel.

Organic electroluminescence display panel, color shift reducing method and manufacturing method thereof and display device

The present disclosure relates to a display substrate, a method for preparing the same, and a display device. The display substrate of the present disclosure includes a base substrate, a pixel definition layer located on the base substrate, and a first pixel and a second pixel that are adjacent to each other and defined by the pixel definition layer, in which a spacer function layer for blocking hole transport between adjacent pixels is arranged at at least a part of a contact interface between the second hole transport layer in the second pixel and the light function layer in the first pixel. By providing the spacer function layer, the present disclosure effectively prevents the migration of holes between the hole transport layers of adjacent pixels or between the hole transport layer and the light emitting layer, thereby avoiding accompanying light emission between adjacent pixels.
