  • Publication number: 20160027410
    Abstract: Various display device implementations disclosed herein include display drivers with enhanced capabilities. In some implementations a display driver may be capable of updating a display while a central processing unit (CPU) is switched off or operating in a sleep mode. Some such display drivers may include a display driver clock and a display driver memory. The display driver may be capable of receiving image data from the CPU, including image data for display updates, and storing received image data in the display driver memory. The display driver may be capable of updating the display with stored image data at times indicated by the display driver clock. Some display drivers may include a graphics processing unit capable of generating image data for updates of the display. In some such implementations, the graphics processing unit may be capable of dithering image data.

  • Publication number: 20130257880
    Abstract: This disclosure provides systems, methods, and apparatuses for illumination using illumination systems having a light guide. A light source is configured to inject light into a light input edge of the light guide. The light guide is configured to recirculate the injected light therein such that the light passes back and forth across the light guide one or more times. The light guide includes light-turning features that extract light out of the light guide. To promote light recirculation, the light-turning features have a per-pass light extraction efficiency of about 50% or less and one or more edges of the light guide may be reflective. The light extracted out of the light guide by the light-turning features may be used to illuminate a display.

  • Publication number: 20130106712
    Abstract: This disclosure provides systems, methods and apparatus related to touchscreens where glare from locations behind a front surface are reduced. In certain implementations, a bulk diffuser can be provided at one or more locations between a cover plate and a touch panel of a touchscreen or between the touchscreen and a display device. Various properties associated with the bulk diffuser, including a haze level and thickness, can be selected so as to yield a desired glare reduction in touchscreen devices that utilize different displays. Such displays can include an interferometric modulator-based display, as well as other types of displays.
