Overview

The LC4100C is a common driver for large-scale dot

matrix LCD panels. It includes a 240-bit bidirectional shift

register and 4-level LCD driver circuits. The number of

bits can be further increased by using the provided input

and output pins to connect multiple LC4100Cs in cascade.

The LC4100C and LC4101C form a large-screen LCD

panel driver chip set.

Features

• Fabricated in a CMOS (P-sub) high-voltage process.

• LCD drive voltage: 36 V

• Logic system power-supply voltage: 3.0 to 5.5 V

• Slim chip (output pads are concentrated on one of the

longer sides)

• 240 outputs (pad pitch: 70 µm)

• Bidirectional shift register

• The shift register can be split into two 120-bit registers.

• DISPOFF function that locks the drive voltages output

to the LCD at fixed levels.

• Display duty: 1/160 to 1/480
