Zusammenfassung:	Disclosed are a method for expressing a tactile image to prevent an electric field generated by a tactile image from interfering with a touch operation during a touch operation through a capacitive touch screen panel, and a touch screen device for performing the same. The touch screen device includes a tactile touch panel, a touch voltage applying unit, and a tactile voltage applying unit. The tactile touch panel includes a plurality of touch driving lines and a plurality of touch sensing lines to perform a touch function and a haptic function. The touch voltage applying unit applies the touch driving voltage to the tactile touch panel. When the touch sensing voltage corresponding to a user′s touch operation is received through the touch sensing line, the tactile voltage applying unit applies the tactile voltage corresponding to the displayed image to the tactile touch panel during a blank period in which the touch driving voltage is not applied. 정전용량 방식의 터치스크린 패널을 통한 터치 동작시 촉각영상에 의해 발생되는 전기장이 터치 동작을 방해하는 것을 방지하기 위한 촉각영상 표현방법 및 이를 수행하기 위한 터치스크린 장치가 개시된다. 터치스크린 장치는 촉각 터치패널, 터치전압 인가부 및 촉각전압 인가부를 포함한다. 촉각 터치패널은 복수의 터치 구동라인들과 복수의 터치 센싱라인들을 포함하여 터치 기능과 햅틱 기능을 수행한다. 터치전압 인가부는 터치 구동전압을 촉각 터치패널에 인가한다. 촉각전압 인가부는 사용자의 터치 동작에 대응하는 터치 센싱전압이 터치 센싱라인을 통해 수신되면, 터치 구동전압이 미인가되는 블랭크 구간 동안, 표시되는 영상에 대응하는 촉각전압을 촉각 터치패널에 인가한다.
