Abstract :
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.
