Abstract:
A touch screen device includes a touch panel, a touch driver, a touch sensing driver, and a controller. The touch panel includes a plurality of driving lines extending in a first direction and a plurality of sensing lines extending in a second direction. The touch driver outputs a driving signal to the driving lines. The touch sensing driver receives a sensing signal from the sensing lines. The controller determines a sensing parameter corresponding to an accumulative folding number of the touch panel and controls the touch driver and the touch sensing driver based on the sensing parameter.
