An organic light-emitting device includes a substrate, on which a transparent electrode and a further electrode are applied. An organic light-emitting layer is arranged between the electrodes. At least one optical scattering layer is arranged on a side of the transparent electrode facing away from the organic light-emitting layer.

In example implementations, a display is provided. The display includes a cover lens, a phosphorescent component, a display module and a processor. The phosphorescent component is located adjacent to the cover lens. The display module is located adjacent to the phosphorescent component opposite the cover lens. The processor is communicatively coupled to the display module to cause the display module to generate a desired image that activates corresponding portions of the phosphorescent component before the display is powered down.

Disclosed are a display panel and a display device. The display panel includes a panel body, the panel body including a display area and a non-display area around a periphery of the display area; and a decoration portion provided on the panel body and located in the display area.

A transparent display apparatus is provided that is constructed to transmit or block a light of images selectively according to a supply of electric power to a conventional transparent organic light emitting diode. The transparent display apparatus includes a transparent organic light emitting diode having a glass substrate, a transparent anode, a hole transport layer, an emitting layer, an electron transport layer and a transparent cathode. The transparent display apparatus includes an insulating layer stacked on the transparent cathode, and first and second transparent ITOs stacked on the insulating layer to deliver electromotive force onto an entire surface and to transmit or block the light of images according to the on/off state of a power source. The transparent display apparatus also includes an electro chromic layer provided between the first and the second transparent ITOs and including transparent and colorless chemicals. The electro chromic layer forms a color through oxidation-reduction reaction of the chemicals according to the on/off state of the power source to absorb or block the light of images. The transparent display apparatus further includes a substrate stacked on the second transparent ITO.

An EL panel including: a light-transmissive substrate; an EL element including a light-emitting medium layer interposed between a cathode and an anode, the EL element being provided on one surface of the light-transmissive substrate; and a protection sheet on the other surface of the light-transmissive substrate of the EL element. The protection sheet has a surface opposite to the light-transmissive substrate, the shape of the surface includes rounded convex shapes and prism shapes. Each of the rounded shapes has an apex that is a center point of a cross-section farthest from a bottom surface where the cross-section is parallel to the bottom surface of the unit convex shape and the area becomes smaller in a direction from the bottom surface of the rounded convex shape to a top portion thereof.

The invention relates to a radiation-emitting device (600), which comprises a substrate (100), an inner optoelectronic component (300) and an outer optoelectronic component (200) which at least partially laterally surrounds the inner optoelectronic component (300). Further, the radiation-emitting device (600) has a cover element (500) which is arranged on the optoelectronic components (200, 300) and comprises a first contact element (521), connected to a first electrode surface of the inner optoelectronic component (300) in an electrically conductive manner, and a second contact element (522) connected to a second electrode surface of the inner optoelectronic component (300) in an electrically conductive manner.

A display device includes a display panel having a display area and a non-display area surrounding the display area, and a decorative film disposed on the display panel. The decorative film includes a porous layer disposed on the display panel and including a plurality of pores, and a decorative layer which overlaps the non-display area and is disposed in the porous layer. Accordingly, the decorative layer which is partially disposed is formed in the porous layer so that a step caused by the decorative layer is not formed or minimized to reduce the thickness of the decorative film. As a result, the design the display device can be slim, and a flexible display device with an excellent folding reliability can be provided based on the display device.
