Abstract

A touch panel electrical device includes a touch panel, a notice signal generator and a processing unit. The processing unit is electrically connected with the touch panel and the notice signal generator respectively. The touch panel senses a touched position on the touch panel. The processing unit includes a notice-generating module. The notice-generating module makes the notice signal generator generate a notice sound signal or a notice vibration signal according to the touched position to notice a user a touched instruction corresponding to the touched position he/she touches.
