Abstract
A composite display device includes a control unit, and first and second display units. The first display unit is coupled electrically to the control unit for displaying a first frame under control of the control unit. The second display unit is disposed beneath the first display unit, is coupled electrically to the control unit for displaying a second frame under control of the control unit, and has a refresh rate greater than that of the first display unit. The first display unit has a first display region that overlaps at least a portion of the second display unit and that is operable to permit the second frame to be visible therethrough under control of the control unit.
