Abstract: A display panel is described that has stretching units connecting display units. Each of the stretching units includes an annular deformation portion and connection portions, where one end of each of the connection portions is connected to the deformation portion while the other end of each of the connection portions is connected to the display unit. When the display panel is stretched, the deformation portion of the stretching unit is elastically deformed.

Abstract: Disclosed is an organic light-emitting display substrate, including a substrate and a pixel defining layer on the substrate which includes a plurality of dams crisscrossing in a display area of the substrate to define a plurality of pixel units and define the boundary of the display area, wherein the pixel defining layer further includes a groove arranged on a top surface of each dam, the grooves at least define one frame-shaped area, at least one pixel unit is arranged in each frame-shaped area, and the grooves are used for accommodating a solvent when forming an organic light-emitting element by inkjet printing. Also disclosed is a manufacturing method of an organic light-emitting display substrate and a display device. The present invention can improve the film forming effect of a film layer formed on the substrate, so that the brightness of a display image of the display device is more uniform.

Abstract: The present invention provides an organic light emitting display device, belonging to the field of display technology, being capable of solving the problem, in an existing organic light emitting display device, of shortened service life of an organic light emitting diode due to moisture escape from the thin film transistor layer or the like. The organic light emitting display device of the present invention comprises a first pixel defining layer doped with a desiccant, which absorbs moisture escaping from an array substrate or the like during the use of the organic light emitting display device, thus improving the ageing and shrinkage of some pixels in the organic light emitting display device and prolonging the service life of the organic light emitting display device.

Abstract: The present disclosure discloses an electroluminescent device and a display apparatus. This electroluminescent device comprises: a transparent anode, an electroluminescent layer, and a transparent cathode, which are sequentially provided on a substrate; and a reflective layer is provided on one of the side of the transparent anode away from the electroluminescent layer or the side of the transparent cathode away from the electroluminescent layer. In the technical solution described above, the functions of an electrode and reflection are achieved by the use of a transparent electrode and a reflective layer respectively, rather than the use of a metal reflective electrode, such that the problems of the plasma effects of metal reflective electrodes have been solved.
