Title:
A touch screen system and a drive method for the same
Document Type and Number:
Japanese Patent JP5992718
Kind Code:
B2
Abstract:
A touch screen system includes a touch screen panel including first lines, second lines crossing the first lines, a plurality of sensing cells formed at the crossing regions between the first lines and the second lines, a driving circuit for sequentially applying a driving signal to the first lines, a first sensing circuit for receiving capacitance change information sensed by the first lines, and generating a first sensing signal corresponding to the capacitance change information, a selecting unit for selectively coupling the first lines to the driving circuit or the first sensing circuit, a second sensing circuit for receiving the capacitance change information sensed by the sensing cells from the second lines and generating a second sensing signal corresponding to the capacitance change information, and a processing unit for receiving a sensing signal from the first sensing circuit and/or the second sensing circuit and determining a detected touch position.
