Abstract
A position sensible liquid crystal display device includes a first substrate having a plurality of scanning lines, data lines, thin film transistors and pixel, and a second substrate having a plurality of first lines formed along the scanning lines and a plurality of second lines formed along the data lines, for position sensing. The black matrix is used as the position sensor input device.
Claims9
A position sensor input device on a first substrate comprising:
- a grid pattern;
- a driving signal applying section;
- an equipotential sustaining resistor electrically connected to the driving signal applying section;
- and
- a plurality of equipotential compensating resistors connecting the equipotential sustaining resistor to the grid pattern,
- wherein the equipotential sustaining resistor includes a plurality of first resistance bodies arranged in one direction at fixed intervals, and at least two second resistance bodies disposed between and connected to adjacent first resistance bodies.
