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.

Claims

1. A system comprising:

a host processor including at least one core and a peripheral controller, wherein the peripheral controller is coupled to the host processor,

wherein the peripheral controller is further configured to interface with a touch controller and to receive mapping information from the host processor and to communicate the mapping information to the touch controller,

wherein the mapping information comprises coordinate information to identify a primary region of a display of the system including an active touch input region and a secondary region of the display including an inactive touch input region;

a memory, coupled to the touch controller, configured to store the mapping information, wherein the touch controller is coupled to the peripheral controller, wherein the touch controller includes a first logic to use the mapping information in the memory to filter touch data received from a touchscreen from being communicated to the peripheral controller when the touch data corresponds to a user touch within the secondary region and to communicate the touch data to the peripheral controller and when the touch data corresponds to the user touch within the primary region, the first logic is further configured to communicate the touch data to the peripheral controller when the touch data is within a control panel region of the display and to otherwise filter the touch data, wherein the touch data is separate from the mapping information, wherein the host processor is to be in a low power state when the touch controller performs the touch data filtering, and wherein the host processor is inactive in the low power state, wherein the touchscreen, coupled to the touch controller, is configured to receive the user touch and to communicate the touch data to the touch controller; and

a display logic, coupled to the processor, and the display, configured to control the display to display content in the secondary region based on one or more of configuration of the system, information from one or more environmental sensors, a type of content to be displayed, and a mode of the primary region wherein a content in the primary region is independent of the content in the secondary region.

2. The system of claim 1, wherein the peripheral controller is to be in a low power state when the touch controller performs the touch data filtering, wherein the peripheral controller is inactive in the low power state.

3. The system of claim 1, wherein the peripheral controller is to be in a low power state when the user touch is within the secondary region, wherein the peripheral controller is inactive in the low power state.

4. The system of claim 1, wherein the peripheral controller is configured to receive the mapping information from system software that executes on the at least one core.

5. The system of claim 1, wherein the peripheral controller is configured to communicate an identification of the control panel region of the display to the touch controller, and the system is to wake up from the low power state responsive to receipt of the touch data.

6. The system of claim 1, wherein the secondary region includes at least one soft button, and the touch controller is to cause haptic feedback to be provided to the user when the touch data is received within the at least one soft button, while the peripheral controller is in a low power state.

7. The system of claim 1, wherein the touch controller is to enable an optical scanner within a first scan region of the touchscreen responsive to receipt of the touch data within the first scan region, to cause illumination of the first scan region responsive to receipt of the touch data within the first scan region, and to enable the optical scanner within the first scan region and the first scan region illumination while a remainder of the touchscreen is in a low power state.

8. The system of claim 1, further comprising:

at least one sensor to sense presence of the user; and

the display logic to receive an output of the at least one sensor and to control a first size of the primary region and a second size of the secondary region based at least in part on the output.

9. The system of claim 8, wherein the display logic is to cause the display to display user selected content for a first user in the secondary region when the at least one sensor senses presence of the first user.

10. The system of claim 1, wherein the display logic is to control the secondary region to display at least one application shortcut, and responsive to user selection of the at least one application shortcut, to control at least a portion of the primary region to display a user interface of the user selected application.

11. The system of claim 1, wherein the display logic is to cause the display to render content based on an interaction with a second system in proximity to the system, including to cause the display to render call information in the secondary region when the second system receives a call, the second system comprising a smartphone.

12. The system of claim 1, wherein the display logic is to enable the secondary region when the primary region is in a low power state, and to render notification content in the secondary region when the primary region is in the low power state.

13. The system of claim 1, further comprising a location sensor coupled to the display logic, wherein the display logic is to cause the display to render first content in the secondary region when the system is in a first location and to cause the display to render second content in the secondary region when the system is in a second location, the first and second locations detected by the location sensor.

14. A system comprising:
