A cathode ray tube (CRT) device increases image resolution using spatial
or temporal techniques. The CRT device includes a plurality of electron
guns that each produce an electron beam and a plurality of separate
phosphor dots, each corresponding to one of a plurality of primary
colors. Certain ones of the phosphor dots form a color spot of a single
primary color when impacted by an electron beam. The CRT device also
includes steering electronics coupled to the plurality of electron guns
to guide the electron beams to project on the phosphor dots to form a
plurality of color spots each indicating a different one of the primary
colors. The steering electronics direct the electron beams to separate
and shift the color spots indicating the different primary colors from
one another. In one embodiment, a subpixel clock is coupled to the
steering electronics to effect subpixel rendering on the CRT device.
