Abstract
An image display device includes two data signal line drive circuits and two scan signal line drive circuits configured differently from each other. Different data signal line drive circuits and scan signal line drive circuit are compatible with different display formats. A display can be produced in the most suitable display format, and power consumption also can be reduced, by switch operating drive circuits according to the kind of input video and environmental conditions. Further, an image can be written over another image by writing video signals to signal lines with a time lag using a plurality of drive circuits; therefore, a superimposed display can be produced without externally processing the video signals. Thus, both a satisfactory image display and low power consumption can be achieved in an image display device.
