Abstract:
An electronic device having a liquid crystal shutter is disclosed. A liquid crystal shutter is provided in an area formed by expanding a liquid crystal display. The liquid crystal shutter includes a rear polarizer, a rear glass substrate, a segmented electrode, a liquid crystal, a counter electrode, a front glass substrate, a shutter aperture, and a front polarizer. A camera module is disposed behind the rear polarizer. A voltage applied to the segmented electrode can be controlled to visually expose or hide the lens of the camera module from a shutter aperture.
