Abstract

A touch panel apparatus includes a first electrode substrate including a first conductive film, a second electrode substrate having four corners and including a second conductive film, a first power-feed terminal, a second power-feed terminal, a third power-feed terminal, and a fourth power-feed terminal respectively provided on the four corners, and a controller. The controller selects at least a potential difference having a largest potential difference value among the first, second, third, and fourth potential differences. The controller calculates a positional relationship between two points where the first and second conductive films contact each other based on the selected potential difference having the largest potential difference value.
