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.

The present disclosure provides a color changing apparatus. The color changing apparatus includes a solar cell assembly to absorb solar energy and converse the solar energy to thermal energy or electromagnetic radiation. The color changing apparatus also includes a color changing element to be in contact with the solar cell and display different color features by absorbing the thermal energy or electromagnetic radiation provided by the solar cell assembly.

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.

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.

A system and method for resolving the blank screen issue when switching between graphics processing units. The system and method provide a graphics adapter LCD timing controller (Tcon) with a frame buffer specifically dedicated to storing previously presented screen data for use when switching graphic processing units. The system further includes a protocol comparator unit within a serial-to-parallel converter and a memory controller coupled to the protocol comparator.

Seamless switching between graphics controllers

A structure of a light guide plate comprising a light guide plate and a plurality of transparent elements is disclosed. The light guide plate comprises at least onelight incident surface, a light scattering surface and a light emitting surface. The light scattering surface has a plurality of notches and these transparent elements are disposed therein. The transparent elements refractive index is different from that of the light guide plate. By disposing these transparent elements, the light scattering surface can improve light scattering effect. In addition, a back light module comprising a linearlight source and a light guide plate structure mentioned above is also disclosed. The linearlight source is disposed next to the light incident surface of the light guide plate.

An illumination module of light emitting elements is provided. The present illumination module includes a printed circuit board having a one-dimensional array of light emitting elements arranged thereon and a reflecting layer on the surface of the printed circuit board with the light emitting elements arranged thereon. The reflecting layer provides reflecting means for the light emitting elements, improving utilization of the light emitting from the light emitting elements, and thus increasing the luminance of the illumination module of light emitting elements.
