Abstract
A unique intra-dot/inter-dot scanning system which gives superior quality speed performance. The intra-dot and inter-dot scanning system is applicable to both serial and line impact dot matrix printers, line and serial thermal printers, ink jet, laser and LCD printers, as well as computer monitors and television. The scanning is perpendicular to the beam's motion over the tube and one synchronized cycle is completed while the beam travels one-half dot diameter to three dot diameters. In the preferred embodiment, the raster scanning system is a cathode ray tube display having a source of an intensity modified electron beam and a main means for deflecting the beam to create a series of horizontal sweeps of the beam from the top to the bottom of a display screen; the deflection means comprises a secondary means for deflecting the electron beam; and, the driver means comprises signal producing means for applying a repetitive sinusoidal electrical signal to the deflection means.
