Patent ID: 7268748

Claim:
A cathode ray tube (CRT) device comprising: a plurality of electron guns to produce a plurality of electron beams; a plurality of separate phosphor dots each corresponding to the one of a plurality of primary colors; certain ones of the plurality of phosphor dots forming a color spot of a single primary color when impacted by one of the electron beams; the plurality of said color spots of said single primary color forming a primary color plane; and steering electronics coupled to the plurality of electron guns to guide the electron beams to project on the plurality of separate phosphor dots to form a plurality of color spots each indicating a different one of the plurality of primary colors, the steering electronics directing the electron beams to separate and shift the plurality of the color spots forming a first primary color plane indicating one of the primary colors from the plurality of the color spots forming a second primary color plane indicating a different one of the primary colors such that the first primary color plane is partially offset in two dimensions from a converged position with respect to the second primary color plane.
