    Abstract: An operation support device supports input operations on a coordinate input device configured to detect change in electrostatic capacitance. The operation support device includes a main shaft support member placed on the coordinate input device, an operation member, a support plate, a first rotating plate, and a first member. When, in conjunction with the operation member, a state in which the support plate and the first rotating plate make contact with each other changes to a state in which the support plate and the first rotating plate are separated from each other, difference between a distance from an end portion of the first member to the coordinate input device and a distance from a detection end portion of the second member to the coordinate input device decreases.

    Abstract: An operation support device that supports an input operation to a coordinate input device for detecting a change in electrostatic capacitance, the operation support device, comprises: an operation member; a first rotation plate that moves in a vertical direction in conjunction with the operation member; and a first member that includes a conductive first shaft part that protrudes from the first rotation plate toward the coordinate input device, and a conductive first end part. In conjunction with a pressing operation performed on the operation member to a first stage, the first shaft part and the first end part come into contact with each other.

    Abstract: An LCD includes a liquid crystal panel having a TFT substrate, a CF substrate, and a liquid crystal layer interposed between the two substrates; a TFT ambient light photosensor having a semiconductor layer for detecting external light; a photodetector unit having a capacitor in which a predetermined reference voltage is charged and a voltage charged by leakage current of the TFT ambient light photosensor is lowered; and an ambient light photosensor reader unit for reading a voltage charged in the capacitor for a predetermined read period. The photodetector unit is disposed on a first surface of the TFT substrate that is in contact with the liquid crystal layer, and the surface of the photodetector unit except for the semiconductor layer and its periphery is covered by a light-shielding layer. Malfunction or reduced sensitivity of an ambient light photosensor due to light from backlights is prevented with a simple structure.
