Device and method for driving display panel

摘要

A display panel driving device that can obviate the need for constant current driving circuits in an anode driver circuit, in which a light emission column electrode lines is opened in a light emission period during scanning of each line of a display panel, and parasitic capacitors of light emitting elements are used to allow leak current from the combined parasitic capacitors of the non-scanned elements to the scanned elements to serve as the light emission current of the scanned elements. <IMAGE>
