Abstract

In an embodiment, a system includes a peripheral controller to interface with a touch controller and to communicate mapping information to identify primary and secondary regions of a display. The touch controller includes logic to filter touch data when it is for a touch within the secondary region and to communicate the touch data to the peripheral controller when it is for the user touch within the primary region. In an embodiment, display logic may determine when and how to use a display bezel area for displaying content, via a combination of criteria. Decision vectors (such as sensors, device configuration, content type, primary display activity) may enable/disable display areas for rendering, with independent control of each side of the bezel. Content can be rendered based on primary display content, environment, other devices and user preferences. Other embodiments are described and claimed.
