An apparatus and method is provided for removing smudges ( 506, 706, 806, 906 ) including oils and dust from portable electronic displays. The apparatus comprises a display device ( 110, 150, 500, 700, 800, 900, 1000 ) positioned within a housing ( 102, 104, 808 ), comprising a transparent cover ( 302, 502, 702, 802, 902, 1002 ) having a surface ( 508, 908 ) viewable through an opening in the housing ( 102, 104, 808 ) and a susceptibility to receiving contaminants ( 506, 706, 806, 906 ). A vibration device ( 504, 704, 804, 904, 1004 ) is positioned against the transparent cover ( 302, 502, 702, 802, 902, 1002 ) to provide motion ( 510 ) in a direction parallel to the surface, thereby causing the contaminants to move ( 708 ) across the surface ( 508, 908 ). The contaminants ( 506, 706, 806, 906 ) may then be hidden by the housing ( 102, 104, 808 ) or ejected by a motion ( 912 ) perpendicular to the surface by another vibrating device ( 911 ). Electronic circuitry ( 505 ) is provided for activating the vibration device ( 504, 704, 804, 904, 1004 ) either during normal operation of the electronic device or as selected by the user.
