Abstract:
A method of displaying a dynamic infrared image from a two-dimensional array of electricaly resistive infrared emitter elements, comprising:generating a first electrical current through each said emitter element to an electrical ground terminal in response to a first stored analog signal voltage during a first frame display time; heating said emitter element in response to said first electrical current, such that said emitter element emits a pixel of said infrared image during said first frame display time; delivering and storing a second analog signal voltage at each of said emitter elements during said first frame display time, until said second analog signal voltages have been delivered and stored at all of said emitter elements; transitioning from said first frame display time to a second frame display time substantially following consecutively said first frame display time; generating a second electrical current through each said emitter element to said electrical ground terminal in response to said second stored analog signal voltage during said second frame display time; and heating said emitter element in response to said second electrical current, such that said emitter element emits a pixel of said infrared image during said second frame display time; wherein said first analog signal voltage remains electrically isolated from said second analog signal voltage at each of said emitter elements for all times during said first and said second frame display times.
