Combination touch and transducer input system and method

A sensor controller configured to control operation of a combination pen and touch sensor including an array of electrodes, the array of electrodes including first electrodes disposed along a first direction and second electrodes disposed along a second direction different from the first direction,

• wherein the sensor controller is configured:
• (i) to perform touch detection by supplying defined signals to the first electrodes disposed along the first direction and measuring attributes of signals detected by the second electrodes disposed along the second direction, to thereby capacitively detect an object on or near the array of electrodes, (ii) to perform transducer detection by measuring attributes of signals transmitted from the pen-shaped transducer and respectively detected by the first and the second electrodes, to thereby detect a pen-shaped transducer on or near the array of electrodes, and (iii) to time-divisionally control the array of electrodes to respectively detect the object and the pen-shaped transducer by continuously performing the transducer detection upon detecting a signal transmitted from the pen-shaped transducer.

A method of controlling operation of a combination pen and touch sensor including an array of electrodes, the array of electrodes including first electrodes disposed along a first direction and second electrodes disposed along a second direction different from the first direction, the method comprising:

• performing touch detection by supplying defined signals to the first electrodes disposed along the first direction and measuring attributes of signals detected by the second electrodes disposed along the second direction, to thereby capacitively detect an object on or near the array of electrodes,
• performing transducer detection by measuring attributes of signals transmitted from the pen-shaped transducer and respectively detected by the first and the second electrodes, to thereby detect a pen-shaped transducer on or near the array of electrodes, and
• time-divisionally control the array of electrodes to respectively detect the object and the pen-shaped transducer by continuously performing the transducer detection upon detecting a signal transmitted from the pen-shaped transducer.
