Abstract
A display comprises a front-end component having a matrix of neutral light valves that defines the resolution of the display. A backlight unit provides backlighting for the front-end component and has a plurality of individual elements grouped into repeat units, wherein the individual elements in the repeat units differ in color and the repeat units have a resolution less than the display resolution. All individual elements in individual repeat units are capable of simultaneously emitting light incident on more than one neutral light valve.
Claims6
A device for displaying images comprising:
- a front-end component having a plurality of luminance repeat groups, the groups comprising a plurality of neutral light valves, the repeat groups defining a display resolution;
- a backlight unit having a plurality of individual elements grouped into repeat units, the individual elements in the repeat units differ in color, the repeat units have a resolution less than the display resolution, the individual elements in a color unit pixel emitting light in a non-color sequential manner incident on more than one neutral light valve;
- a means for adjusting color contrast and luminous intensity of the display.
