Abstract
An array of light emitting elements comprises an insulating substrate, a dot anode array including a multitude of dot anodes defined by conductors and phosphors formed on the substrate, a thermionic emission cathode disposed in opposing relationship with the dot anode array, and a grid interposed between the cathode and the dot anode array. An accelerating electric field is selectively established between the dot anodes and the cathode to excite the phosphors on the dot anodes with low speed electron beams, thus causing the phosphors to emit light. The array is primarily used in an electrophotographic printer.
