System for reuse of touch panel and controller by a secondary display

Abstract

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for controlling a display device that includes a first display, a touch screen disposed on the first display and a second display. In one aspect, the first display may be disposed on a first side of the display device (e.g., the front side) and the second display may be disposed on a second side of the display device (e.g., the back side). The second display may consume less power than the first display. Even when the first display is switched off, a control system may be configured to control the second display in response to input received from the touch screen disposed on the first display. The control system may be further configured to control the first display in response to input received from the touch screen when the first display is switched on or when the second display is not in use.

Dependencies are inferred from the claim text.
