Abstract
A flat panel display device includes a cathode (58) in parallel opposed position to and vertically separated from an anode (56). Red (46), green (44), and blue (42) subpixels are sequentially arrayed on the anode (56). Electron emitter subpixels (50, 52, 54) are arrayed on the cathode (58) in paired relationship to the red, green, and blue subpixels (46, 44, 42) located on the anode (56). To provide enhanced color performance, the surface area of the blue subpixel (42) is greater than the surface area of either the green subpixel (44) or the red subpixel (46). Additionally, the red subpixel (46) is horizontally shifted toward the green subpixel (44) and away from the blue subpixel (42).

A flat panel display device comprising:
- a cathode arranged in parallel opposed position to and vertically separated from an anode;
- red, green, and blue subpixels sequentially disposed on the anode,
- wherein each subpixel is defined by a surface area on the anode, and
- wherein the surface area of the blue subpixel is greater than the surface area of the red and green subpixels, and
- wherein the surface area of the red subpixel is greater than the surface area of the green subpixel;
- and
- a plurality of electron emission sites disposed on the cathode in spaced relationship to the red, green, and blue subpixels.
A flat panel display device comprising:
- an anode partitioned into a plurality of adjacent anode pixels;
- and
- a red, a green, and a blue subpixels sequentially disposed within each of the plurality of anode pixels,
- wherein each subpixel is defined by a surface area on the anode, and
- wherein the surface area of each blue subpixel is greater than the surface area of each red subpixel and each green subpixel, and
- wherein the surface area of each red subpixel is greater than the surface area of each green subpixel.
A flat panel display device comprising:
- an anode having a plurality of sequentially arranged green, red, and blue subpixels,
- wherein the green subpixel is separated from the blue subpixel by a first separation distance, and
- wherein the red subpixel is separated from the green subpixel by a second separation distance, and
- wherein the first separation distance is less than the second separation distance.
