Power saving display system and method

A method of modulating a multi-pixel display, said method comprising:

• receiving video data;
• defining a modulation period;
• providing a set signal to each pixel of said display during said modulation period;
• providing a reset signal to each pixel of said display during said modulation period, the relative timing of said set signal and said reset signal for each particular pixel depending on said video data and determining the optical output of each particular pixel.

A display comprising:

• a plurality of pixel cells, each pixel cell including a set terminal, a reset terminal, an output terminal, and a set/reset circuit coupled to receive a set signal via said set terminal and a reset signal via said reset terminal;
• and
• means for receiving video data and providing set signals and reset signals to said pixels based on said video data;
• and wherein
• said set/reset circuit responsive to receiving a set signal on said set terminal is operative to assert a first signal on said output terminal and to maintain said first signal on said output terminal until a reset signal is received on said reset terminal;
• said set/reset circuit responsive to receiving a reset signal on said reset terminal is operative to assert a second signal on said output terminal and to maintain said second signal on said output terminal until a set signal is received on said set terminal;
• and
• an optical output of said pixel depends on when said first signal and said second signal are asserted on said output terminal of said set/reset circuit during a predefined modulation period.
