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.
Claims15
A display control film for a display device, comprising:
- an adhesive layer;
- and
- a display control layer over the adhesive layer, the display control layer comprising:
- 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, wherein each adjacent pair of channels of the second set sandwiches a channel of the first set.
A display device comprising:
- a display screen;
- and
- a display control layer over the display screen, the display control layer comprising:
- a set of privacy-gate channels filled with a first electrochromic material to control a view angle of a display from the display screen;
- and
- a set of blue/ultraviolet (UV) light absorption channels filled with a second electrochromic material to control absorption of blue/UV light from the display screen, wherein each privacy-gate channel of the set of privacy-gate channels is placed between and interfaced with two blue/UV light absorption channels of the set of blue/UV light absorption channels.
An electronic device comprising:
- a display device having a display screen;
- and
- a display control layer over the display screen, the display control layer comprising privacy-gate channels separated by blue/UV light absorption channels, wherein
- the blue/ultraviolet (UV) light absorption channels are filled with a second electrochromic material to control absorption of blue/UV light from the display screen;
- and
- the privacy-gate channels are in a forma matrix of longitudinal channels arranged row-wise and column-wise in a plane of the display screen and are filled with a first electrochromic material to control a view angle of a display from the display screen.
