Zusammenfassung:	An LCD panel includes an image capture device having an aperture, thin-film transistor layer, and an electronic ink reservoir. The thin-film transistor layer includes a first portion to provide an image on the LCD panel, a second portion, and a third portion. The second portion corresponds with the aperture, and the third portion immediately surrounds the second portion. The electronic ink reservoir is located proximate to the second and third portions of the thin-film transistor layer, and includes an electronic ink charged with a first charge state. The LCD panel directs the second portion of the thin-film transistor layer to provide a first electrical stimulus in a second charge state opposite to the first charge state to attract the electronic ink to the aperture to form a shutter for the image capture device and to block the aperture.
