Abstract: A flexible OLED display device includes a flexible display panel and a support member. The flexible display panel includes an active area, an extension portion and a bending portion connecting the active area and the extension portion. The support member is located between the active area and the extension portion. The active area, the support member and the extension portion are stacked, and a first distance is set between the support member and the bending portion in an extending direction parallel to the extension portion. The bending portion is substantially of a semicircular shape, and an inner radius of the semicircular shape is equal to a sum of a half of a thickness of the support member and a third distance between an upper surface of the support member and a lower surface of the active area, and the third distance is less than the thickness of the support member.

Abstract: A display substrate includes: sub-pixels on a base substrate and each including a sub-pixel aperture area, a reflective layer, an insulating layer, independent anode patterns, a light-emitting function layer and a cathode. An orthographic projection of the reflective layer onto the base substrate at least partially overlaps an orthographic projection of the sub-pixel aperture area onto the base substrate. Each of orthographic projections of the anode patterns onto the base substrate at least partially overlaps the orthographic projection of the sub-pixel aperture area onto the base substrate. An orthographic projection of the light-emitting function layer onto the base substrate is within the orthographic projection of the sub-pixel aperture area onto the base substrate. An orthographic projection of the cathode onto the base substrate covers the orthographic projection of the light-emitting function layer onto the base substrate.

Abstract: The present application can provide a nanoparticle, a method for patterning a nanoparticle layer and a light emitting device. When the nanoparticle provided by the present application is adopted for manufacturing a light emitting layer of the light emitting device, a cross-linking reaction occurs among first ligands of adjacent nanoparticles under irradiation of ultraviolet light, and the cross-linked nanoparticles may be firmly connected to a front film layer of the light emitting layer, so that when a developing solution is adopted for developing treatment, the cross-linked nanoparticles are not insoluble in the developing solution and are retained while non-cross-linked nanoparticles are dissolved in the developing solution and are separated from the front film layer to be removed, therefore completing patterning of the nanoparticle layer.
