  • Patent number: 7353719
    Abstract: A pressure sensor comprising a plurality of sensor parts arranged in matrix. A first electrode being connected with first wiring and a second electrode being connected with second wiring are disposed oppositely through a cavity part in the sensor part. The second electrode bends to the first electrode side in response to a pressure from a specimen and touches the first electrode upon application of a pressure of a specified level or above. When the specimen is pressed against a pressure detecting region, both electrodes touch each other at a sensor part corresponding to a protrusion of the specimen and are separated at a sensor part corresponding to a recess. When a scanning signal is fed from a scanning circuit to one wiring and presence of a signal flowing through the second wiring is detected by a sensing circuit, a pressure being applied to each sensor part can be detected.

  • Publication number: 20060152660
    Abstract: A liquid crystal display apparatus comprising a first substrate with pixel electrodes formed in regions surrounded by a plurality of scanning lines and signal lines, a second substrate on which a transparent electrode is formed, orientation controlling means formed at least on either the first substrate or the second substrate, alignment films deposited on both substrates to which vertical treatment is applied, and a liquid crystal layer having negative dielectric anisotropy, which is sandwiched between both substrates, wherein liquid crystal molecules are vertically aligned when no electric field is applied to the liquid crystal layer, and tilt to be aligned in directions controlled by the orientation controlling means when electric field is applied to the liquid crystal layer, whereby the orientation controlling means is positioned to be approximately linearly symmetrical by using a scanning line and a signal line as boundaries such that the position of the orientation controlling means in relation to pixel
