ELECTRONIC DEVICE HAVING A TACTILE DISPLAY USING SQUEEZE FILM EFFECT

摘要

The present invention relates to an electronic device comprising a touch screen; a protective panel for protecting the touch screen by covering it; a vibration operator, combined to the protective panel, for vibrating the protective panel; and a control module for collecting location information of input units which are in contact with the protective panel. The control module controls the vibration of the vibration operator according to the location of input units, and forms a squeeze film between the input units and protective panel, thereby reducing the frictional force between the input units and protective panel.
