A display panel with a press sensor, and electronic equipment with a press input function

Japanese Patent JP6069500

B2

An electronic device with pressing input function (1) has a substantially rectangular parallelepiped-shaped housing (50). A display panel with pressure sensor (10) and an arithmetic circuit module (60) are disposed in a housing (50). The display panel with pressure sensor (10) is composed of a pressure sensor (20) and a display panel (30). In the display panel (30), a front polarizing plate (302) is disposed on a front face of a liquid crystal panel (301). In the pressure sensor (20), electrodes (202, 203) are formed on both respective flat plate faces of a piezoelectric film (201) having birefringence. The pressure sensor (20) is disposed between the liquid crystal panel (301) and the front polarizing plate (302) of the display panel (30), and a uniaxial drawing direction (900) of the piezoelectric film (201) is parallel to a polarizing direction (910) of the front polarizing plate (302).
