Overview

The LC4103 is a common driver IC for large-scale dot matrix LCD displays, It includes a 160-bit bidirectional shift register and 4-level LCD drivers. The number of bits can be increased by using the I/O pins provided for cascode connection. In conjunction with the LC4104 segment driver, the LC4103 forms a chip set that can drive large-screen LCD panels.

Features

• High-voltage CMOS (P-sub) process.

• LCD drive voltage : 42V

• Logic system power-supply voltage : 2.7 to 5.5V

• Maximum fcp : 2.5MHz (VDD=5V±10), 200kHz (VDD=2.7 to 4.5V)

• Bidirectional shift register.

• The shift register can be divided into two 80-bit registers (thus allowing two-screen drive).

• DISPOFF function (Holds the LCD drive voltage at a fixed level).

• Slim TAB (160 outputs).

• Display duty ratios : 1/160 to 1/480.

• Package lineup.
