IMAGE DISPLAY APPARATUS |
摘要 |
<P>PROBLEM TO BE SOLVED: To provide an image display apparatus with good image quality in which a variation in brightness of a light emitting element caused by voltage drop of a power source line and by a variation in threshold voltage of a TFT are reduced. <P>SOLUTION: The image display apparatus is equipped with a pixel circuit voltage detection means which selectively generates internal voltages in pixel circuits 2a owned by a plurality of pixels respectively to signal lines 3 and a drive circuit 6 includes a voltage addition means for adding a voltage of the signal line to a signal voltage corresponding to a display image and for outputting the added voltage to the signal line again. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
