DISPLAY PANEL DRIVING-GEAR

摘要

PROBLEM TO BE SOLVED: To provide a display panel driving-gear which eliminates the need for a constant current driving circuit in an anode driver circuit.

SOLUTION: A light emitting column is opened in light emission timing at each line scanning of a display panel and the leakage current from the resultant parasitic capacity of a non-scanning element to a scanning element is determined as the light emission current of the scanning element by utilizing the parasitic capacity possessed by a light emitting element. Scanning is repeated a plurality of times per line and gradation control may be performed according to the number of times of the repetition.
