Abstract: Examples of hinge assemblies are described. In an example implementation, a hinge assembly includes hinge elements which are interconnected to move the hinge assembly between a folded position and an unfolded position. The hinge assembly further includes elastic members disposed between the hinge elements at a first side and a second side thereof. When the hinge assembly is moved from the unfolded position towards the folded position, elastic members at the first side are decompressed and elastic members at the second side are stretched. When the hinge assembly is moved from the folded position towards the unfolded position, elastic members at the first side are compressed and the elastic members at the second side are destretched.

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: The present subject matter relates to techniques for selectively rendering content in 2D view and 3D view, for example, based on a choice of the user. In an example, a display may include a set of light sources and a 3D panel that may further include a 3D lens. In one example, the 3D lens may be selectively positionable in a first position where the 3D lens is positioned in a path of light emitted by the set of light sources.

Abstract: In some examples, a computer-readable medium storing executable code which, when executed by a processor of an electronic device, causes the processor to store a relationship between a user eye gaze pattern and first conditions of the electronic device, identify second conditions of the electronic device, determine whether the second conditions match the first conditions, and responsive to the second conditions matching the first conditions, selectively operate a display panel of the electronic device with differing display characteristics based on the user eye gaze pattern.

Abstract: A foldable hinge is described herein that includes a plurality of interconnected sliding links, wherein each of the interconnected sliding links comprise at least one curved extruding prong and at least one curved rail. The at least one curved rail of a first interconnected sliding link can be coupled to the at least one curved extruding prong of a second interconnected sliding link to form a torque engine. Additionally, the interconnected sliding links can be rotatable based on a pressure applied to the interconnected sliding links. The foldable hinge can also include a plurality of shafts coupled to the plurality of interconnected sliding links, wherein each shaft is coupled to a separate interconnected sliding link.

Abstract: In one example, a display device may include a liquid crystal panel and a direct type backlight unit having a light emitting diode (LED) package disposed behind the liquid crystal panel. The LED package may include a plurality of LEDs. The plurality of LEDs may have a first orientation towards the liquid crystal panel to provide a first viewing angle. Further, the display device may include a control unit to rotate the LED package to allow the plurality of LEDs to have a second orientation towards the liquid crystal panel to provide a second viewing angle. The second viewing angle may be narrower than the first viewing angle.

Abstract: Examples of a hinge for foldable components are described herein. In an example, the hinge can include a plurality of bracing elements, a bracing element from the plurality of bracing elements can be operably coupled to an adjacent bracing element from the plurality of bracing elements, to fold the plurality of bracing elements into an arcuate shape. Each bracing element can be supported and locked against the adjacent bracing element in the arcuate shape. The hinge can further include an end coupler at each longitudinal end of the hinge to couple the hinge to a flexible element.
