A piezoelectric sensor in which position detection and load detection can be achieved. The piezoelectric sensor includes a piezoelectric layer interposed between the upper electrode and the lower electrode. In the piezoelectric sensor, at least one of the upper electrode and the lower electrode includes a plurality of electrodes patterns.

Piezoelectric sensor and pressure detection apparatus

A piezoelectric sensor that can perform position detection and load detection. The touch panel having press detection function can detect the pressing load inputted to the pressing surface. An upper electrode, an upper insert member, an intermediate electrode, a lower insert member, and a lower electrode are arranged away from the pressing surface in this order. Among the upper electrode, the intermediate electrode, and the lower electrode, capacitance detection electrodes Cx, Cy for detecting the pressing position, and detection electrodes S for measuring the electric charge according to the pressure when the operation is inputted to the touch panelhaving press detection function are included. One of the upper insert member and the lower insert member is composed of an insulating body, and the other is composed of a piezoelectric body.

Touch panel having press detection function

[Object] It is an object to provide a mount structure of a touch panel with a vibration function which is superior in impact resistance, dust-proofness, and drip-proofness, and can effectively transmit a vibration of a vibration element. [Solution to Problem] The mount structure of the touch panel with the vibration function is characterized by including a touch panel body, a design sheet bonded to an upper surface of the touch panel body and having a transparent window part and a decorative part surrounding the transparent window part, a vibration element formed in a back surface peripheral part of the touch panel body and hidden by the decorative part, a casing dented so as to have a level difference to allow the above parts to be externally fitted in and having a recess part or an opening part for a display device, and a frame-shaped support part to support the back surface peripheral part of the touch panel body, in its bottom surface, an elastic member frame arranged on the support part and positioned on an outer edge side of the touch panel with respect to the vibrator, and a vibration control unit arranged inside the casing to apply a drive voltage to the vibration element.

Mount structure of touch panel with vibration function

A mounting structure includes a protection panel () with a touch input function for protecting an electronic device display window, mainly formed of the protection panel body made of a resin plate, and a panel fitting portion () of an exterior housing () into which the protection panel () is fitted from outside so that an outer face of the protection panel () is in the same plane as a portion of the exterior housing surrounding the outer face. In this structure, nut mounting holes are formed in a back side rim portion of the protection panel body and nuts () each having a female thread formed in an inner periphery thereof are attached to the respective nut mounting holes, and male screws () are screwed into the respective female threads of the nuts () through through-holes () formed in the panel fitting portion () of the exterior housing ().

Structure and method for mounting protection panel with touch input function

A protection panel for detecting an X-Y coordinate as an operation position from a potential gradient based on a touch operation to a front substrate is provided. A rear substrate () has a first transparent resistive film (A) and a contact point (G) connected to a pair of first terminals (D) through routing circuits (C) so that the contact point (G) is arranged in parallel with the first transparent resistive film (A). When the rear substrate () and a front substrate () are connected, the contact point (G) and an expanded region (Ab) of a second transparent resistive film (A) on the front substrate (), which are arranged opposingly with a predetermined gap, form a switch () for detecting a contact therebetween, based on a voltage detected in the terminals (D,D) of one of the rear substrate () and the front substrate () when a voltage is applied between the terminals (D,D) of the other.
