Abstract: A light emitting and receiving module with heater is provided, which includes a base material. A light emitting and receiving element is disposed on the base material and performs at least one of light reception and light emission. A heater film includes an electrode formed on a base sheet. The heater film is formed so as to cover the light emitting and receiving element. A capacitance detection unit electrically connected to the electrode detects a floating capacitance between the light emitting and receiving element and the heater film. A power source electrically connected to the electrode heats the heater film. A control board switches the connection with the electrode between the capacitance detection unit and the power source.

Abstract: [Object]
To provide a pressure detection panel that allows suppressing the cost required for an FPC and obtaining in-plane uniformity of a detection signal of a pressing force even when a panel size is large.
[Solution]
A pressure detection panel 1 of the present invention includes a surface panel 2 and one strain sensor 3 arranged on a back surface of the surface panel 2 in a strip shape along one side of the surface panel 2. The strain sensor 3 includes sensitive units R1, R2, and R3 at an intermediate portion and both end portions in a longitudinal direction. The adjacent sensitive units, that is, the sensitive units R1 and R2 and the sensitive units R2 and R3, are mutually connected in series by a wiring line 31.

Abstract: A conductive sheet includes a transparent substrate and a plurality of thin metal wires formed in a mesh shape on one surface of the transparent substrate. The plurality of thin metal wires includes an n-sided polygon formed in a virtual pattern and an inverted virtual pattern and six connecting lines. The virtual pattern and the inverted virtual pattern obtained by flipping the virtual pattern horizontally are densely laid such that intersection points disposed on respective sides of the virtual pattern and the inverted virtual pattern are overlapped with each other and that opening regions formed by the plurality of thin metal wires are aperiodically arranged.

Abstract: A touch panel includes: first electrodes disposed in parallel at a position corresponding to a viewing area of a panel member and have a capacitance changing according to a proximity of an object to be detected; second electrodes that intersect with the first electrodes, are disposed in parallel, and similarly change in capacitance; third electrodes disposed in parallel between the first or second electrodes and have electrical resistances changing according to posture and temperature; and fourth electrodes extending along the respective third electrodes and similarly change in electrical resistance. A resistance change rate of the fourth electrodes due to temperature is the same as for the third electrodes. The resistance change rate of the fourth electrodes due to the posture change is 90% or less than for the third electrodes due to the posture change. This allows a pressing force to be accurately measured.
