摘　　要：基于0.35μm二层多晶硅四层金属(2P4M)3.3 V/5 V双电源电压CMOS混合信号工艺,设计了能应用到投影显示的一种分辨率为800×600硅基液晶(LCoS)微显示驱动电路芯片。整个驱动电路采用奇偶列的驱动方案,并且每一列都集成了一个数字模拟转换器(DAC)。为了减少亮度的损失,采用场序彩色法实现彩色显示。像素单元的面积为15μm×15μm,整个芯片的面积大小为14.7 mm×11.4 mm。测试结果表明该芯片在帧频为60 Hz时能正常工作并且能实现256阶灰度的彩色显示。在3.3 V/5 V的双电源电压供电下,整个芯片的功耗大约为100 mW。An 800 × 600 liquid crystal on silicon （LCoS） microdisplay driving circuit for the projection display was designed and fabricated using 0. 35 μm two-poly silicon four-metal （2P4M） 3.3 V/5 V mixed-signal CMOS process. The driving circuit employed the scheme of odd-even column driving and every column integrated a digital to analog converter （DAC）. In order to reduce the loss in brightness, field sequential color operation was adopted. The pixel cell area is 15 μm × 15 μm and the total chip occupies 14.7 mm × 11.4 mm. Experimental results show that the chip can work properly at a frame frequency of 60 Hz, and carry out 256 gray scales colorful display. The power consumption of the total chip is about 100 milliwatts with dual 3.3 V/5 V supply voltage.
