Architecture and method for multi-aspect touchscreen scanning. This architectures employs a single type of circuitry capable to perform both signal generation and signal detection for performing both zone scanning and cross point within a touchscreen to identify a user's interaction with the touchscreen and to discriminate actual touch locations on the touchscreen (including multiple, concurrent user touch locations on the touchscreen). This signal generation/detection circuitry can be implemented multiple times within the architecture (e.g., one for providing/detecting signals of conductors aligned in a first direction across the touchscreen, and another for providing/detecting signals of conductors aligned in a second direction across the touchscreen). Moreover, a combination of both zone scanning and cross point within the touchscreen allows for a very accurate discrimination between false/phantom touch locations and actual/real touch locations made by a user interacting with the touchscreen.
