Title: MULTIPHASE SIGNALING FOR SCAN TIME REDUCTION FOR A TOUCH SYSTEM
Abstract:
A system (100) includes a transmitter (110) to transmit excitation signals (114). At least one of the excitation signals (114) is transmitted to at least one row or column of a touch system (120) and at least one other of the signals is concurrently transmitted to at least one other row or column of the touch system (120). The transmitter (110) generates at least one of the excitation signals at a given phase to one row or column of the touch system (120) and generates the other of the excitation signals at a different phase from the given phase to the other row or column of the touch system (120).
