The invention has high test accuracy and real-time property, simple structure and convenient use and can carry out accurate and comprehensive linear test on the capacitance touch screen.

The device is currently undergoing testing by clients and the company has already started shipping 10.1-inch projective capacitive touch panels and 3d panels.

Those relying on changes in electrical resistance tend to have poorer resolution than is needed for modern applications, while those that rely on capacitance require an ungloved finger.
