<P>PROBLEM TO BE SOLVED: To provide a display device provided with a display panel adapted to an active matrix driving system, which is capable of moving images with a good display quality free from blur and blot and is capable of displaying image information with an appropriate gradations corresponding to image data (display data), and a display driving method thereof. <P>SOLUTION: A light non-emitting operation period Tnem when supply of a light emission driving current to an organic EL element OEL is cut off by application of a power supply voltage Vsc in a low level to a display pixel EM not to cause a light emitting operation, a write operation period Twrt when the display pixel EM is set to a selected state and is made to hold a voltage component corresponding to display data, and a light emitting operation period Tem when the light emission driving current corresponding to display data is made to flow to the organic EL element OEL on the basis of the voltage component held in the write operation period Twrt to cause a light emitting operation are set so as to be included within one processing cycle period Tcyc. <P>COPYRIGHT: (C)2007,JPO&INPIT |
