Input function display device

摘要

An input function display device includes: a position information reading unit that is provided with an imaging element optically reading a position information pattern representing a coordinate position on a plane; and a display unit that performs display on the basis of marks read from the position information pattern recorded in a display area, wherein the display unit includes a transparent conductive film having a conductive pattern in which the position information pattern is applied onto the transparent substrate, and a display portion that performs display using the conductive pattern as a common electrode.

1. An input function display device comprising:
a display unit that displays an image, the display unit including:
a substrate;a pixel electrode over the substrate;a display member over the pixel electrode;a transparent resin film over the display member; anda transparent conductive film on the transparent resin film, the transparent conductive film having a position information pattern that has position coordinate information, and being provided between the transparent resin film and the display member; and a position information reading unit that has an imaging element, wherein the imaging element of the position information reading unit detects the position coordinate information, the display unit displays the image based on the detected position coordinate information by using the position information pattern as a pixel common electrode, the position information pattern is configured of a dot pattern provided at an arbitrary position of only matrix intersections of a plurality of first lines and a plurality of second lines perpendicular to the plurality of first lines so that the dot pattern is physically connected to one of the matrix intersections, the plurality of first lines and the plurality of second lines are electrically connected to the pixel electrode so as to apply a voltage to the display member, first intervals between the plurality of first lines are different from each other; second intervals between the plurality of second lines a e different from each other; and a rotational state of the position information pattern is determined by the position information reading unit.
