TOUCH SENSING METHOD AND TOUCHSCREEN APPARATUS

摘要

A touch sensing method may include setting at least one touch group according to levels of a plurality of digital data according to changes of capacitance in a plurality of nodes; detecting two nodes having highest levels of the plurality of digital data among the touch group; generating a plurality of combinations by matching nodes defining two vertices, among four vertices of the touch group, facing each other with the two nodes having the highest levels among the plurality of digital data; selecting one combination among the plurality of combinations; and setting an examination region executing a touch separating algorithm according to two points positioned two respective line segments connecting the respective nodes of the selected combination.
