Integrated multi-touch surface having varying sensor granularity
First Claim
1. A method for controlling the power of a touch enabled device comprising a touch enabled display, the touch enabled display comprising a plurality of data lines, a plurality of stimulus lines, and a plurality of touch pixels placed along the display at a predetermined initial granularity at a first time, the method comprising:
- dynamically selecting a first portion of the display which has a first level granularity at a second time;
dynamically changing the granularity of touch pixels to the first level at a display hardware level by activating the plurality of stimulus lines,wherein the granularity of touch pixels in a second portion, different than the first portion, of the display is at the predetermined initial granularity, different from the first level granularity, during the second time; and
dynamically selecting a third portion, different from the first and second portions of the display, which has a level of granularity different from the predetermined initial granularity at a third time.

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.
