摘要

在LCoS硅背板中集成了8位伽玛补偿数字数据驱动器。我们采用了4点参考电压的传统寄存器梯形D/A转换器用于LCoS显示(VGA)。南开大学微显示实验室研制了以场序色(FSC)模式工作的LCoS微显示器，其数据驱动程序可实现256级灰度。本文详细介绍了利用级联电阻串提供静态电压输出的概念。

LCoS chip with integrated 8-bit gamma compensated digital data driver

8-bit gamma compensated digital data driver was integrated in LCoS silicon backplane. We have applied conventional register ladder D/A converter with 4 points reference voltage for LCoS displaying (VGA). The LCoS microdisplay operating with fields sequential color (FSC) mode has been developed in the Microdisplay lab of Nankai University, and the data driver can realize 256 level gray scales. In this paper, the concept that utilizes cascaded resistor strings delivers a static voltage output were shown in detail.
