    Abstract: A sensor for detecting a target in a non-contact manner includes a first electrode; a second; a third electrode that is disposed between the first electrode and the second electrode; and a determination circuit that, in operation, detects entry of the target into a first region by detecting a change of first electrostatic capacitance, which is electrostatic capacitance of the first electrode, and detects entry of the target into a second region by detecting a change of second electrostatic capacitance, which is electrostatic capacitance of the second electrode. An electric potential of the third electrode is more negative than electric potentials of the first electrode and the second electrode. At least a part of the second region at least partially surrounds an outer edge of the first region in plan view.

  • Patent number: 9917144
    Abstract: A display panel includes an EL panel section, a CF panel section, and a sealing resin layer. In the EL panel section, the surface of a sealing layer has a projected and recessed shape in a Z-axis direction as a whole, wherein a light-emitting region corresponding to a region between banks is a recessed section, and a non-light-emitting region corresponding to a top portion of the bank is a projected section. The sealing resin layer includes a first sealing resin layer and a second sealing resin layer. Prior to performing heating or light irradiation in a step of forming the first and second sealing resin layers, the viscosity of a second non-fluid resin constituting the second sealing resin layer is lower than the viscosity of a first non-fluid resin constituting the first sealing resin layer.

  • Publication number: 20170214401
    Abstract: A switch includes a sensor that, in operation, outputs a detection signal indicative of approach of a target without making contact with the target, and a control circuit that, in operation, generates an operation signal for operating the apparatus on the basis of the detection signal supplied from the sensor. The control circuit generates the operation signal when the detection signal becomes smaller than a second threshold value within a predetermined period from a time when the detection signal exceeds a first threshold value that is different from the second threshold value and does not generate the operation signal when the detection signal becomes smaller than the second threshold value after elapse of the predetermined period from the time when the detection signal exceeds the first threshold value.
