Abstract
PURPOSE:To obtain an excellent picture by increasing the luminous brightness of memory width, etc., by providing an interval for widening the pulse width of a maintenance pulse at the time of generating a timing pulse. CONSTITUTION:A composite video signal inputted from terminal 6 is separated by signal separator circuit 7 into video signal 8, and horizontal and vertical synchronizing signals 9, and signal 8 is applied from horizontal driver circuit 12 to horizontal electrode groups H1...Hm of an EL panel after passing through signal processing circuit 10. On the other hand, a signal from clock pulse generating circuit 13 causes timing pulse generating circuit 14 to generates timing control signals, by which selective pulse and erasing pulse generating circuits 15 and 16 generate their outputs and supply them to matrix circuit 18; and then, the composite output of matrix circuit 18 is applied to vertical driver circuit 19 and the output of maintenance pulse timing signal generating circuit 17 is also sent to circuit 19. Consequently, an interval for widening the pulse width of the maintenance pulse at the time fo the generation of the timing pulse is provided so as to increase the brightness of the memory width, thereby obtaining an excellent picture.
