General Description
ML2002 (COG) LCD driver can be cascaded to increase the number of segments drive, with Static
driving it can form a single piece of 48 (1 ICs) or 96 (2 ICs cascaded) segments driver. With 1/2 Duty, the
number of segment drive would be doubled. It targets at custom TN LCD COG Module product which
requires the best quality of TN LCD technology and small to medium number of segment display.
ML2002 series driver offers the best contrast, the widest viewing angle, the widest range of operating
voltage and temperature when compared to the high duty cycle driver. EMI and Noise protection circuit
has been added which tailor made for COG application.
