Abstract:
An active matrix display comprising:a first pixel region having first pixels in a matrix form;first signal lines for supplying image signals to said first pixels;a first signal line drive circuit for driving said first signal lines;a second pixel region having second pixels in a matrix form;second signal lines for supplying image signals to said second pixels;a second signal line drive circuit for driving said second signal lines;scanning signal lines for supplying scanning signals to said first and second pixels;a scanning line driver circuit for driving said scanning signal lines;control means for controlling a supply of clock pulses for said first and second signal line drive circuits, wherein said control means halts the supply of said clock pulses for said first signal line drive circuit during the scanning of said second signal line drive circuit, and wherein said control means halts the supply of said clock pulses for said second signal line drive circuit during the scanning of said first signal line drive circuit; andswitching means for switching operation between said first and second signal line drive circuits alternately,wherein said control means comprises:a frequency division circuit for dividing first clock pulses to said scanning line driver circuit;a first AND gate responsive to an output from the frequency division circuit and to second clock pulses to generate the supply of clock pulses into said first signal drive circuit; anda second AND gate responsive to an inverted output from the frequency division circuit and the second clock pulses to generate the supply of clock pulses into said second signal drive circuit.
