FLEXIBLE DISPLAY AND TOUCH DRIVER IC ARCHITECTURE

摘要

A display and touch driver architecture is described that includes a plurality of source drivers and a processing system. The processing system operates receivers within the source drivers to selectively receive sensing data from the receivers and determines positional information based on the sensing data. The processing system may selectively operate different source drivers in low power modes and/or for capacitive sensing based on the determined positional information.
