SED1766

160 SEGMENT DRIVER WITH GRAY SCALE

■ DESCRIPTION

The SED1766 is a 160-bit output LCD segment (column) driver for driving high-capacity LCD panels at duty

cycles higher than 1/100 (up to 1/500). The LSI uses a PWM (Pulse Width Modulation) algorithm to achieve

16-, 8- and 4-level gray-scale display without ghosting. Also, an external pulse controller circuit can be used

to control the gray-scale pulse position within the horizontal interval.

This device has been designed for low output resistance, making the SED1766 suitable for STN-type LCD

panels, and yielding gray-scale displays with few contrast disparities.

The LSI features a wide range of LCD drive voltages.

The device uses a high-speed daisy-chain enable system which decreases power consumption and

eliminates the need for separate enable signals for each driver.
