US 9,870,041 B2 · Integrated multi-touch surface having varying sensor granularity

Abstract

This relates to an event sensing device that includes an event sensing panel and is able to dynamically change the granularity of the panel according to present needs. Thus, the granularity of the panel can differ at different times of operation. Furthermore, the granularity of specific areas of the panel can also be dynamically changed, so that different areas feature different granularities at a given time. This also relates to panels that feature different inherent granularities in different portions thereof. These panels can be designed, for example, by placing more stimulus and/or data lines in different portions of the panel, thus ensuring different densities of pixels in the different portions. Optionally, these embodiments can also include the dynamic granularity changing features noted above.

Claims20

Dependent claims

A method for operating a touch screen included in a touch enabled device, the method comprising:

operating one or more portions of the touch screen in at least one of a plurality of operating modes, the plurality of operating modes including:
a first operating mode associated with a first level of granularity, and
a second operating mode associated with a second level of granularity, different from the first level of granularity;
dynamically selecting a portion of the touch screen based on one or more applications running on the touch enabled device;
and
dynamically switching an operating mode of the selected portion based on the one or more applications running on the touch enabled device.
