4320-Hz LED Display With Pulse-Width Modulation by Use of a Nonlinear Clock

We have developed an extremely high-frame-rate LED display, which features 4320-Hz refresh rate. The displayed image is perfectly photographed even with a high-speed camera. In order to show 14-bit full-color images at such a high-frame rate, we have specially designed an LED driver that employs a n...

Summary:We have developed an extremely high-frame-rate LED display, which features 4320-Hz refresh rate. The displayed image is perfectly photographed even with a high-speed camera. In order to show 14-bit full-color images at such a high-frame rate, we have specially designed an LED driver that employs a nonlinear clock. Use of the nonlinear clock enables us to realize pulse-width modulated output with inverse gamma correction with a compact circuit size.
