Input device and I/O-integrated display |
摘要 |
The invention concerns an input device including an input receiving panel and a stylus enabling an input, the input device sensing an input by means of capacitive coupling between a panel electrode on the input receiving panel and a stylus electrode on the stylus, and includes: a signal supply section supplying an input sensing signal to the panel electrode; a signal detecting circuit detecting a signal generated in the stylus electrode; and an input sensing section comparing the input sensing signal with the detection signal detected by the signal detecting circuit and sensing an input based on a result of the comparison. An input-sensing digital code is superimposed on the input sensing signal. This allows for further reduction in the possibility of false sensing caused by noise than conventional techniques.
