Abstract
An exemplary electronic device includes a first display and a second display. The first display includes a number of first pixels. Each first pixel defines a first display region. Each first display region displays first visual content when voltages are applied to the first pixel and displays no first visual content when no voltage is applied to the first pixel. Each first display region is transparent or translucent when displaying no first visual content. The second display includes a number of second pixels. Each second pixel defines a second display region for displaying second visual content. The first visual content is viewable whether or not the second display displays the second visual content, and the second visual content is viewable when one or more first display regions corresponding to the second display region are transparent or translucent.
