A method is provided for fabricating a structure including a two-dimensional material. The method includes a step of providing an electrically-conducting substrate and a step of forming a solid organic spacer layer on the electrically-conducting substrate. The method further includes depositing the two-dimensional material on the spacer layer. A structure formed according to the method includes an electrically-conducting substrate and a layer of a two-dimensional material. A solid organic spacer layer is arranged between the electrically-conducting substrate and the layer of the two-dimensional material.

A flexible display comprises a flexible substrate made of plastic material, a display element on a first surface of the flexible substrate, and a surface residual film containing at least one of a metal material or a metal oxide material. The surface residual film is bonded to at least a part of a second surface of the flexible substrate. The second surface is opposed to the first surface. A method for manufacturing a flexible display comprises preparing a glass substrate, forming adhesive material film on the glass substrate, the adhesive material film being made of at least one of a metal material or a metal oxide material, and forming a flexible substrate from plastic material on the adhesive material film.

An electronic device may have a pair of elongated housings. A flexible display may be placed in a first position in which the display is retracted within one of the housings and a second position in which the flexible display is deployed and extends between the housings in a planar shape for viewing by a user. Support structures such as rigid slats that run parallel to the housings and bistable slats that run perpendicular to the rigid slats may be used to support the flexible display. Speakers, microphones, cameras, and other components can be mounted in the housings. The housings may be held together using magnets and may contain electrical components such as integrated circuits, batteries, and other devices. The components may be mounted on printed circuit boards that rotate within a rotating roller around which the display is wrapped when retracted.

A display device includes a first substrate, an organic EL layer formed on the first substrate and curved in each pixel, and color filters disposed in the respective pixels, and curved to match the organic EL layer. With this configuration, a change in the chromaticity and brightness of the display device depending on a viewing angle of a user is reduced.

A coating can be provided on a substrate. Fabrication of the coating can include forming a solid layer in a specified region of the substrate while supporting the substrate in a coating system using a gas cushion. For example, a liquid coating can be printed over the specified region while the substrate is supported by the gas cushion. The substrate can be held for a specified duration after the printing the patterned liquid. The substrate can be conveyed to a treatment zone while supported using the gas cushion. The liquid coating can be treated to provide the solid layer including continuing to support the substrate using the gas cushion.

A package structure, a preparation method for the package structure, and a display panel are provided. The package structure includes a first inorganic layer, a photocatalytic layer, and a second inorganic layer that are sequentially stacked, where the photocatalytic layer includes a photocatalytic material and a co-catalyst. The photocatalytic material and the co-catalyst are used cooperatively to catalyze the decomposition of water vapor, the photocatalytic material includes graphitic carbon nitride (g-C3N4) particles, and the co-catalyst includes perylene tetracarboxylic acid (PTA). The photocatalytic layer possesses high catalytic efficiency and excellent stability. In the case where cracks are generated at the package structure, water vapor invading through the cracks is decomposed and consumed through an oxidation-reduction reaction, and then decomposition products are respectively discharged.
