  • Patent number: 9928796
    Abstract: A scanning signal is precisely output to a scanning signal line corresponding to a row range even in a case where a plurality of scanning signals (including a precharge signal) are output at the same time. A display control circuit of the display device sets row selection enable signals at H level so that main charging periods are set in a range from an ith row to an mth row, which corresponds to a moving image region, and precharging periods corresponding to the main charging periods are also set. Accordingly, a precise scanning signal in which a precharging period having a necessary length is set and no unnecessary precharging period is set at all is output to each of scanning signal lines connected to a scanning signal line driving circuit, so that deterioration of display quality is prevented.

  • Patent number: 9785278
    Abstract: An erroneous operation is prevented in a display device detecting a touch operation for a display face and a part other than the display face. A display device (1) of the present invention includes: an operation acquiring unit (51) that acquires detection signals transmitted from detection electrodes arranged on a touch panel (14); a use form determining unit (55) that determines a holding form based on a touch position of the touch operation for an end face of the display device; and an insensitive area setting unit (58) that sets an insensitive area on the operation detecting member after the holding form is determined. The operation acquiring unit does not acquire detection signals transmitted from the detection electrodes included in the set insensitive area among the detection electrodes.

  • Patent number: 9753325
    Abstract: The present invention suppresses expansion and contraction of a display image that occur in association with a change in the shape of a lens. A display device is equipped with an acquisition unit (50) that acquires a deviation amount by which a measurement position on a lens is displaced due to a change in the lens shape from a reference position before the change of the shape. A video data interpolation unit (51) prepares post-interpolation video data on the basis of the deviation amount.

  • Patent number: 8941800
    Abstract: A reflective imaging element includes: a plurality of holes penetrating through the plate-like substrate along a thickness direction thereof; two orthogonally-disposed specular elements on inner walls of the plurality of holes; a first principal face on which light from an object is received; a second principal face parallel to the first principal face; and two taper elements opposing the two specular elements. The two taper elements each have a first side parallel to the first principal face, a second side orthogonal to the first principal face and to the first side, and a hypotenuse meeting the first and second sides and constituting an angle ? with the second side. An angle constituted by a normal direction of the first principal face and an incident direction of light striking the first principal face defines an incident angle ?, such that, in a range of 0°<?<90°, the angle ? satisfies (90°??)/4??.
