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.

Claims

1. 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.

2. The display of claim 1, wherein the individual elements simultaneously emit light.

3. The device of claim 2 wherein the adjusting means is a controller that enables the viewer to select a resolution of the display to have a higher resolution display mode or a lower resolution display mode.

4. The device of claim 3 wherein

the lower resolution display mode is enabled by selecting a luminance signal having a matrix M×

N that drives luminance repeat groups to perform as individual luminance pixels, and

the higher resolution display mode is enabled by selecting another luminance signal having a matrix P×

Q, the matrix P×

Q being larger than a matrix M×

N, the another luminance signal drives individual neutral light valves to perform as discreet luminance pixels.

5. The display of claim 4, wherein the backlight unit is a field emission device.

6. The display of claim 5, wherein the front-end component is a liquid crystal device.
