Title:
タッチパネル
Document Type and Number:
Japanese Patent JP5761465
Kind Code:
B2
Abstract:
The present invention provides a touch panel that can detect a touch position and a pressing amount and can be formed to be thin. A touch panel (1) includes a dielectric film (2) and a piezoelectric film (3). A first capacitance detection electrode (8) is disposed on an upper main surface (9) of the dielectric film, a second capacitance detection electrode (11) and a first piezoelectric voltage detection electrode (12) are disposed between a lower main surface (10) of the dielectric film and an upper main surface (13) of the piezoelectric film (3), and a second piezoelectric voltage detection electrode (17) is disposed on a lower main surface (14) of the piezoelectric film. The first capacitance detection electrode includes plural sub-electrodes (18) extending in a first direction, the second capacitance detection electrode includes plural sub-electrodes (19) extending in a second direction orthogonal to the first direction, and the first piezoelectric voltage detection electrode includes plural sub-electrodes (20) disposed between the plural sub-electrodes (19).
