Display device and method for driving display device

摘要

A display device for displaying images corresponding to digital signals information comprising a display panel with a plurality of display pixels arranged in matrix form near the intersecting points of a plurality of scanning lines and a plurality of signal lines which intersect perpendicularly with each other; a scanning driver circuit for sequentially applying scanning signals; a signal driver circuit comprising a plurality of gradation current generation supply circuit sections comprising a module current generation circuit which generates a plurality of module currents corresponding to each digital signal bit based on reference voltage; a gradation current generation circuit which integrates selectively each of the module currents, generates gradation currents and supplies each of a plurality of the signal lines; a reference voltage generation circuit which applies in common the reference voltage to a plurality of the gradation current generation circuits sections.
