摘要

我们开发了一款超高帧率LED显示屏，其刷新率为4320 Hz。即使使用高速照相机也能完美地拍摄所显示的图像。为了以如此高的帧速率显示14位全彩图像，我们专门设计了一种采用非线性时钟的LED驱动器。非线性时钟的使用使我们能够以紧凑的电路尺寸实现具有逆伽马校正的脉宽调制输出。

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 nonlinear clock. Use of the nonlinear clock enables us to realize pulse-width modulated output with inverse gamma correction with a compact circuit size.
