According to one embodiment, a display device includes a display panel having a display area, a first substrate opposed to the display panel, an adhesive layer arranged between the display panel and the first substrate, a first electrode formed at the first substrate in a peripheral area arranged along at least a part of an outer edge of the display area, a second electrode formed at the display panel in the peripheral area. In the display device, the first electrode includes a first portion which is opposed to the second electrode and a second portion which is not opposed to the second electrode, and the adhesive layer is interposed between the first portion and the second electrode.

This touch-sensitive sensor includes a layer of piezoelectric material interposed between, on the one hand, first and second electrically-conductive elements and, on the other hand, at least one third conductive element including a surface opposite at least one of the first and second conductors.

An optical detection sensor functions as a proximity detection sensor that includes an optical system and a selectively transmissive structure. Electromagnetic radiation such as laser light can be emitted through a transmissive portion of the selectively transmissive structure. A reflected beam can be detected to determine the presence of an object. The sensor is formed by encapsulating the transmissive structure in a first encapsulant body and encapsulating the optical system in a second encapsulant body. The first and second encapsulant bodies are then joined together. In a wafer scale assembling the structure resulting from the joined encapsulant bodies is diced to form optical detection sensors.

A contact and/or proximity-sensitive input device has a cover plate with a light-transmissive control section facing a user of the input device and forming a control field for the user. A light-transmissive sensor film has at least one capacitive sensor field. A carrier plate carries at least one lighting device. The input device also has a light-transmissive decorative film with at least one decorative element. The film is a separate component from the sensor film so that the decorative film can be produced independently of the sensor film and can be adapted simply to desired variants of the input device. The carrier plate, decorative film, sensor film and cover plate are arranged successively in such a way that the light emitted by the lighting device passes through the decorative film, sensor film and control section of the cover plate.

A biometric recognition apparatus with deflection electrode includes a substrate, a multi-function electrode layer including a plurality of sensing electrodes, a plurality of deflection electrodes and at least one suppressing electrode. Each of the sensing electrodes is at least partially surrounded by a corresponding deflection electrode and each of the deflection electrodes is at least partially surrounded by the suppressing electrode. The biometric recognition apparatus further includes a switching circuit layer having a plurality of selection switches and conductive wires, at least a part of the selection switches and the conductive wires are electrically connected to the sensing electrodes. By above arrangement of the sensing electrodes, the deflection electrodes and the suppressing electrode, the sensing sensibility and signal to noise ratio can be enhanced, thus increasing the sensing distance between sensing electrode and user finger.

An appliance that includes: a front panel having a touch point; a touch board including: a first side attached to a location on a rear surface of the front panel, the location corresponding to the touch point; a second side opposite to the first side; a pressing portion; and one or more holes defined around the pressing portion and configured to enable an elastic movement of the pressing portion; a holder that is attached to the second side of the touch board, the holder having a receiving portion; a piezo disc configured to be inserted in the receiving portion of the holder and contact the pressing portion; a guide board having a seating hole configured to receive the holder and the piezo disc; and a first adhesive member attached to the first side of the touch board and configured to attach to the rear surface of the front panel.

The described technology includes an apparatus comprising a proximity sensor pad and booster element located between an antenna and the proximity sensor pad, wherein voltage level of the booster element at least ten percent higher than voltage level of the proximity sensor pad. Implementations of the booster element may be made of metal or metal-ink and may have U-shape or L-shape.

A touch-sensitive glass barrier has a conductive coil affixed to the first side of a glass barrier, a capacitor connected to the conductive coil to form a resonator, and an inductance-to-digital converter (LDC) connected to drive an alternating current through the resonator. The LDC determines whether a conductive target has touched the second side of the glass barrier at a point opposite the conductive coil; and responsive to determining that the conductive target has touched the second side of the glass barrier at the point, provides a signal.

An input device has one or more electrodes configured for capacitive sensing, an electronic circuit, one or more conductive feed line(s) connecting the one or more electrode(s) with the electronic circuit, wherein the device is configured to increase or decrease a signal received from at least one of the electrodes through an associated feed line in function of at least one other signal from another electrode.

A method for manufacturing a capacitive operation device includes the steps of: preparing a capacitance sensing member including a base film, a sensing electrode formed on the base film, a cover film, and an adhesive layer; preparing an operation panel having a recessed portion having a shape that overlaps an outer edge of the sensing electrode in a stacking direction of the operation panel and the capacitance sensing member; disposing the operation panel and the capacitance sensing member so as to face each other; and bonding the capacitance sensing member to the back surface of the operation panel by pressing the capacitance sensing member against the back surface of the operation panel. In the bonding step, the capacitance sensing member and the operation panel are bonded together while a gas therebetween is being directed to the recessed portion.
