Multi-layered sensing with multiple resolutions
First Claim
1. A method comprising:
- displaying, by a device, multiple icons at a display structure of the device,wherein the display structure comprises;
a display screen for displaying the multiple icons;
a low resolution sensor situated above the display screen for detecting touches;
a separation layer situated above the low resolution sensor;
a high resolution sensor situated above the separation layer for detecting fingerprints; and
a protective layer situated above the high resolution sensor;
activating, by the device, the low resolution sensor of the display structure for detecting touches at the protective layer;
detecting, by the device, using the low resolution sensor, an object touching a location of the display structure at which one of the multiple icons is displayed; and
responsive to detecting the object touching the location of the display structure at which the one of the multiple icons is displayed;
deactivating, by the device, the low resolution sensor; and
activating, by the device, at least one area of the high resolution sensor of the display structure for detecting fingerprints, the at least one area corresponding to the location of the display structure at which the one of the multiple icons is displayed.

Abstract
A display component (108) displays multiple icons that a user can touch. A multi-layered sensing component (104) includes at least a high resolution sensing component (204) and a low resolution sensing component (202). The low resolution sensing component is activated to detect objects touching the multi-layer sensing component. In response to the low resolution sensing component detecting an object touching one of the multiple icons, the low resolution sensing component is deactivated and at least a portion of the high resolution sensing component over the touched icon is activated. The high resolution sensing component senses the user'"'"'s fingerprint, which is authenticated. After sensing the user'"'"'s fingerprint, the high resolution sensing component is deactivated and the low resolution sensing component is reactivated.
