Abstract: The present subject matter relates to display control in display devices. In an example implementation, a display control layer for a display device comprises a first set of channels filled with a first electrochromic material to control a view angle of a display from the display device, and a second set of channels filled with a second electrochromic material to control absorption of blue/ultraviolet (UV) light from the display device. Each adjacent pair of channels of the second set sandwiches a channel of the first set.

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.

Abstract: The present subject matter describes illuminating a display panel. In an example implementation, a plurality of light guide films is stacked together, with a light guide film positioned over another light guide film of the plurality of light guide films. Each of the light guide films of the plurality is associated with a light source. The light source for a respective light guide film is to launch light through at least one light incident surface of the respective light guide film, where the light guide assembly is to guide light from the light source to illuminate the display panel.
