<P>PROBLEM TO BE SOLVED: To secure sufficient time for surely executing the respective compensation operation as the respective compensation periods of threshold compensation and mobility compensation. <P>SOLUTION: In an organic EL display device having the respective compensation function of the threshold compensation and the mobility compensation, when the respective compensation operations of the threshold compensation and the mobility compensation are executed by a period of 1H by every pixel column for compensation, the respective compensation periods of the threshold compensation and the mobility compensation are set as long by executing operations of preparation for the threshold compensation for fixing gate potential Vg and source potential Vs of a driving transistor to predetermined potential, respectively before entering a 1H period for the pixel columns for compensation. <P>COPYRIGHT: (C)2009,JPO&INPIT |
