TOUCH PANEL DEVICE AND METHOD FOR CALCULATING TOUCH POSITION COORDINATE OF TOUCH PANEL |
摘要 |
Disclosed is a touch panel device having a plurality of touch sensors for detecting a touch position that includes a coordinate calculation unit that calculates a touch coordinate from an output value of at least one of the plurality of touch sensors; and a coordinate correction unit that receives a calculated touch coordinate from the coordinate calculation unit, includes a lookup table that stores a correspondence relationship between a plurality of real touch position coordinates and a plurality of calculated touch coordinates, and extracts one of the plurality of real touch position coordinates as a corrected touch coordinate that corresponds to the calculated touch coordinate. |
