Datasheet LC4131C Datasheet (SANYO)

Overview

The LC4131C is a common driver for large-scale dot
matrix LCD panels. It includes a 120-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 LC4131Cs in cascade.
The LC4131C and LC4104C 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: 2.7 to 5.5 V

• fcp max: 2.5 MHz

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

• Bidirectional shift register

• The shift register can be split into two 60-bit registers.
(Two screens drivable)

• DISPOFF function that locks the drive voltages output
to the LCD at fixed levels.

• Display duty: 1/160 to 1/480

• Appropriate for COG (chip on glass) mounting. (A gold
bump structure is adopted in the pad areas.)
