Description

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.
