Abstract
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.
