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).
