Abstract
A touch panel device includes a touch panel and two or more controllers. The touch panel includes four regions. Each region includes a plurality of driving conductors extended along a first direction, and a plurality of sensing conductors extended along a second direction perpendicular to the first direction. Each controller is in charge of one of the region. Since the length of each driving conductor and each sensing conductors is one half of that of the conventional driving conductor and sensing conductor, each controller controls one fourth of the area of the touch panel, and is responsible for one fourth of the capacitance of the touch panel. The touch panel device can be well controlled by the controller without using a single controller with higher detecting sensibility and cost.
