Abstract :
We have developed two types of high-frame-rate LED displays, both of which employ pulse-width modulation by use of nonlinear clock. One of the LED display shows a static image at 4,320 frames per second so that the displayed image is perfectly photographed by a high-speed camera. The second type of the LED display shows a dynamic movie at 960 frames per second. Furthermore, the developed high-frame-rate LED display was utilized for hand-waving steganography.
