    • The LCOS element driving circuit is provided with a plurality of D/A converters for effecting D/A conversion on pixel data which is fed to each pixel of a LCOS element on a pixel group-by-pixel group basis and delay devices for delaying clock signals to provide timing for each D/A conversion operation. The clocks to be fed to the respective D/A converters are delayed via the delay devices to cause variation in delay time, so that output pixel signals from the D/A converters can be applied to the LCOS element in a synchronized state. This makes it possible to drive the LCOS element at high speed.
    • LCOS元件驱动电路设置有多个D / A转换器,用于对像素数据进行D / A转换,像素数据以逐像素组的形式馈送到LCOS元件的每个像素,延迟器件用于延迟时钟 信号以提供每个D / A转换操作的定时。 要馈送到相应D / A转换器的时钟经由延迟装置被延迟以引起延迟时间的变化,使得来自D / A转换器的输出像素信号可以以同步状态施加到LCOS元件。 这使得可以高速驱动LCOS元件。
