Abstract:
1. A method of detecting a press operation position on a upper substrate of a touch panel, the method comprising: (A) providing a touch panel which includes (B) causing the belt-shaped upper conductive layers and the belt-shaped lower conductive layers to contact each other at a first position and a second position by pressing the upper substrate at the first position and the second position; (C) while the belt-shaped upper conductive layers and the belt-shaped lower conductive layers are contacting each other at the first position and the second position, applying a voltage to the ends of the lower resistive layer and measuring a voltage value at the first upper electrode and a voltage value at the second upper electrode; (D) while the belt-shaped upper conductive layers and the belt-shaped lower conductive layers are contacting each other at the first position and the second position, applying a voltage to the ends of the upper resistive layer and measuring a voltage value at the first lower electrode and a voltage value the second lower electrode; (E) detecting a location of the first position in the second direction based on the voltage value at the first upper electrode measured in (C); (F) detecting a location of the second position in the second direction based on the voltage value at the second upper electrode measured in (C); (G) detecting a location of the first position in the first direction based on the voltage value at the first lower electrode measured in (D); (H) detecting a location of the second position in the first direction based on the voltage value at the second lower electrode measured in (D); and (I) determining a location of the first position and the second position based on a result of (E), (F), (G), and (H).
