CONTACT DETECTING DEVICE AND DISPLAY DEVICE
First Claim
1. A contact detecting device comprising:
- a contact responding section configured to produce an electric change in response to an object to be detected coming into contact with or proximity to a detecting surface; and
a contact driving scanning section configured to scan application of driving voltage to said contact responding section in one direction within said detecting surface, and control output of said electric change in time series,wherein said contact driving scanning section performs a plurality of scans of different regions of said contact responding section in parallel with each other, and outputs a plurality of said electric changes in parallel with each other;
and N sets of a predetermined number k of detecting lines are arranged for N regions of said contact responding section;
and driving lines are arranged at the contact driving scanning section,and detection lines in each region of contact responding section are completely separated from detection lines of another region.
