Abstract
A single view display of reduced power consumption is provided. The display comprises a display device for displaying the single view and an optical system for concentrating light modulated by the single view into a reduced angular range. A viewer direction determining system determines the direction of a viewer relative to the display and controls the display device and the optical system so that the angular range includes the direction of the viewer.
Claims22
A single view display comprising:
- a display device for displaying a single view;
- an optical system for concentrating light modulated by said single view into a reduced angular range, said optical system including a backlight for illuminating said display device;
- and a determining system for determining a direction of a viewer relative to said display and for controlling at least one of said display device and said optical system by refracting an angular range of illumination from said backlight so that said reduced angular range includes said determined direction.
A display method for using a display to obtain reduced power consumption, said method comprising the steps of:
- displaying in a display a single view;
- concentrating light in an optical system which is modulated by said single view into a reduced angular range, said optical system including a backlight for illuminating said display device;
- and
- determining in a determining system a direction of a viewer relative to said display and for controlling at least one of said display device and said optical system by refracting an angular range of illumination from said backlight so that said reduced angular range includes said determined direction.
