Abstract:
A display apparatus comprising:a) an active matrix circuit comprising:i) a first circuit comprising plural first switch means arranged along plural rows and plural columns, scanning lines for connecting commonly per each column said plural first switch means and for supplying thereto an image signal, vertical scanning means for driving the scanning line, and horizontal driving means for driving the signal line; andii) a second circuit comprising plural memory means, respective ones of said plural memory means connected to every plural first switching means for holding the image signal supplied from the signal lines at turning on of said first switch means on the scanning line scanned by said vertical scanning means, plural second switch means connected and arranged per every one of said plural memory means for outputting collectively each of memory contents from said plural memory means, plural pixel electrodes connected and arranged per every one of said plural second switch means, and reset means for collectively resetting the image signal supplied per every one of said pixel electrodes;b) a light source for emitting successively a first emission light color and a second emission light color, different from each other in respectively different periods; andc) control means for controlling said active matrix circuit and said light source, so that said first circuit operates to output from the signal line the image signal for the first emission light color, and at that time said second switch of said second circuit is set at an off state, and while the image signal is held at each of said plural memory means, said light source emits the second emission color, and said reset means operates after a termination of light emission of the second emission color, and thereafter, said second switch is turned on to output collectively the memory contents from each of said plural memory means, and at that time said light source emits the first emission color.
