A display device includes a cover window; a first display module and a second display module attached to a lower surface of the cover window; a heat-dissipating plate attached to the first display module and the second display module; and a core plate disposed under the cover window and configured to receive the first display module, the second display module, and the heat-dissipating plate thereon, wherein a heat-dissipating plate includes: a first flat portion attached to the first display module; a second flat portion attached to the second display module; and a bridge connecting the first flat portion and the second flat portion to each other and having a shape different from a shape of each of the first flat portion and the second flat portion.

A display apparatus with a novel structure is provided. The display apparatus includes a display surface, a flexible non-rectangular substrate over which part of the display surface is formed, and a light-emitting device formed over the flexible substrate. The light-emitting device includes pixel regions formed in a matrix. The display surface has a convex or concave region when part of the flexible non-rectangular substrate is bent. A novel light-emitting apparatus, a novel display apparatus, a novel input/output apparatus, or a novel semiconductor apparatus can be achieved. The display apparatus enables the degree of design flexibility of a display apparatus to be increased and design of the display apparatus to be improved.

An electronic device with high luminance is provided. The electronic device includes a first display apparatus, a second display apparatus, and an optical element. The first display apparatus includes a first light-emitting element and the second display apparatus includes a second light-emitting element. A color of first light emitted from the first light-emitting element is different from a color of second light emitted from the second light-emitting element. An optical element is provided between the first display apparatus and the second display apparatus. The optical element includes a first light guide plate and a second light guide plate.

An organic light-emitting diode display panel is disclosed. By using four display panels sequentially disposed in a stack arrangement from top to bottom, light emitted in a same direction from each of the display panels, and subpixels of the four display panels not overlapping one another, a screen resolution of the organic light-emitting diode display panel can increase by three times without increasing pixel density of masks or density of array layers.

A method to reduce slack in a display layer of a flexible electronic-display device comprises arranging the display layer slidably relative to an electrically conductive support layer of the electronic-display device; arranging a dielectric layer between the electrically conductive support layer and an electrically conductive sublayer of the display layer; and charging the electrically conductive sublayer relative to the electrically conductive support layer to operatively urge the display layer toward the electrically conductive support layer.

The present application provides a display panel and a display device. The display panel includes a driving backplane and display components. A first binding terminal of each of the display components includes a first terminal portion and second terminal portions. One end of the second terminal portion is electrically connected to the first terminal portion, and the other end is electrically connected to the driving backplane. The second terminal portion is arranged in a dense and spaced columnar structure to alleviate an existing problem that display panel and motherboard have malfunction joints existing in the conventional seamless spliced display technologies.
