摘要

我们开发了一种用于三面板彩色投影仪的高度集成的液晶硅显示器。硅面板采用定制的0.5 /spl μ m 3金属CMOS工艺设计制作，空间分辨率为1024/spl倍/768像素。像素间距为13.8 /spl mu/m，填充系数为91%。硅面板内集成了6位数字数据驱动器和伽马校正电阻网络，以实现真正的灰度和全彩图像表示。在CMOS兼容电压下，采用优化的混合扭曲向列和双折射电池结构制作了高对比度的显示器。3.5 Vrms时，对比度为70:1。利用小型光学投影仪，显示了图像逼真、色彩饱和度高的特点。

Liquid-crystal-on-silicon XGA projection display using mixed-mode twisted nematics

We have developed a highly integrated liquid-crystal-on-silicon display for three-panel color projector. The silicon panel was designed and fabricated by a custom 0.5 /spl mu/m 3-metal CMOS technology with a spatial resolution of 1024/spl times/768 pixels. The pixel pitch was 13.8 /spl mu/m and the fill factor was 91%. 6-bit digital data drivers and gamma-correction resistor network were integrated within the silicon panel for true gray scale and full color image representation. The display was made with an optimized mixed twisted nematic and birefringence cell configuration for high contrast ratio at CMOS compatible voltage. Contrast ratio was 70:1 at 3.5 Vrms. With a compact optical projector, vivid image and good color saturation were demonstrated.
