TOUCH SENSING DEVING AND DRIVING METHOD THEREOF

摘要

PURPOSE: A touch sensing device and a driving method thereof are provided to improve touch sensitivity in a capacitive touch screen by preventing the generation of parasitic capacitance between conduction patterns. CONSTITUTION: A touch screen comprises row and column conductive patterns(R1-Rn,C1-Cm) and common electrode facing the conduction patterns. A row driver(21) successively supplies high potential power voltage to a column direction conductive pattern and floats the other column direction conduction patterns. A column driver(22) successively supplies the high potential power voltage to the column direction conductive pattern and floats the other column direction conductive patterns.
