Orthogonal multi-row touch panel stimulation

摘要

Control circuitry for a touch panel includes a touch panel interface, a memory comprising scanning logic, and a controller in communication with the memory and the touch panel interface. The controller is operable, when the scanning logic is executed, to energize a first and a second row in the touch panel simultaneously, a first time; obtain a first signal measurement along a column intersecting the first and second rows; energize the first and the second row in the touch panel simultaneously, a second time; obtain a second signal measurement along the column; and determine a first pixel value and a second pixel value along the column from the first signal measurement and the second signal measurement.

1. A method, comprising:
energizing a first and a second row in a touch panel simultaneously, a first time; obtaining a first signal measurement along a column intersecting the first and second rows while energizing the first time; energizing the first and the second row in the touch panel simultaneously, a second time; obtaining a second signal measurement along the colum while energizing the second time; determining a first pixel value along the column responsive to the first signal measurement and the second signal measurement; and determining a second pixel value along the column responsive to the first signal measurement and the second signal measurement.
