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 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.
