Abstract: The present subject matter relates to display screens. In an example, a display screen includes a first set of pixels, where micro-LEDs of the first set of pixels are to emit light in a first direction from the display screen, and a second set of pixels, where micro-LEDs of the second set of pixels are to emit light in a second direction from the display screen. The second direction is different from the first direction.

Abstract: Various examples provide a method of making a hydrophobic surface for an object. According to the method, a hydrophobic coating may be applied to an original surface of the object. A microstructure may be formed on the original surface of the object. The hydrophobic surface of the object may be obtained with the microstructure submerged by the hydrophobic coating. The microstructure may be a rough structure including micro-sired portions, and may have greater hardness than the hydrophobic coating.

Abstract: One example provides a method of manufacturing. The method comprises oxidizing, using plasma, a first surface of a substrate comprising a metal-material. The method further comprises cutting into the substrate through the oxidized first surface to expose a non-oxidized second surface of the substrate, the second surface not parallel to the first surface. The method further comprises disposing, using electrophoretic deposition, a coating layer over the exposed second surface to form an article having the oxidized first surface and the coated second surface.

Abstract: The present subject matter relates to display devices. In an example implementation, a display device comprises a display unit having color pixels and tracks of a black matrix covering spaces between the color pixels. The display device also comprises a display control layer over the display unit. The display control layer has longitudinal channels separated by transparent substrates and overlapping the tracks of the black matrix in one direction. The longitudinal channels comprise a first set of channels filled with undoped bi-stable liquid crystals to control a view angle of a display from the display unit, and a second set of channels filled with doped bi-stable liquid crystals to control absorption of blue/ultraviolet (UV) light from the display unit.

Abstract: A device comprises a display that includes an aperture layer, a plurality of light sources, and a piezo material. The aperture layer includes a plurality of apertures. The plurality of light sources is arranged to correspond to the plurality of the aperture. The piezo material is coupled to the light sources and is configured to alter a distance between the light sources and the corresponding apertures.

Abstract: An input mouse may include a top button, a first wall rearward of the top button to underlie a palm of a user and a second wall forming an exterior of the input mouse. The first wall is formed from a material composition comprising a first polymer encapsulating thermally conductive particles. The second wall is formed from a thermally conductive material. A solid-state Peltier heat pump has a first face thermally coupled to the first wall and a second face thermally coupled to the second wall.
