Abstract:
An image display apparatus comprising:a plurality of scanning wires distributively arranged in an image display region for transmitting a scanning signal; a plurality of signal wires arranged to intersect with said plurality of scanning wires in said image display region for transmitting a signal voltage; a plurality of current driven electro-optical display elements each arranged in a pixel region surrounded by each said scanning wire and each said signal wire and connected to a common power supply; a plurality of driving elements each connected in series with each said electro-optical display element, connected to said common power supply, and applied with a bias voltage to drive each said electro-optical display element for display; and a plurality of memory control circuits each for holding said signal voltage in response to said scanning signal to control driving of each said driving element based on said held signal voltage, wherein each said memory control circuit samples and holds said signal voltage while blocking a bias voltage from being applied to each said driving element, and subsequently applies each said driving element with said held signal voltage as said bias voltage.
