Abstract:
1. An image display apparatus comprising: a plurality of scanning wires 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 said scanning wires and said signal wires connected to a common power supply; a plurality of driving elements arranged in said pixel region connected with said electro-optical display elements; and a plurality of memory control circuits each including a sampling switch and a driving switch for holding said signal voltage in response to said scanning signal and to control driving of said driving elements based on said held signal voltage, wherein said memory control circuit samples and holds said signal voltage while blocking a bias voltage from being applied to each of said driving elements by closing said sampling switch and opening said driving switch, and subsequently applies said held voltage signal to said driving elements as said bias voltage by opening said sampling switch and closing said driving switch.
