Abstract
A touch-screen system comprises adjacent first and second touch-screen sensors, first and second digitizers, and synchronization, tracking, and return logic. Each of the first and second digitizers is coupled electronically to the respective touch-screen sensor and configured to provide a pen signal responsive to action of a pen on the touch-screen sensor. The synchronization logic is configured to synchronize the pen to the first and second digitizers and to enable pen tracking by any of the first and second digitizers conditionally, based at least partly on the first and second pen signals. The tracking logic is configured to define a region of precision scanning of the first or second touch-screen sensor by the respective first or second digitizer, based at least partly on the first and second pen signals. The return logic is configured to expose a result of the precision scanning to an operating system of the touch-screen system.
