The LC79431KNE is a large-scale dot matrix LCD common driver LSI. The LC79431KNE contains an 80-bit bidirectional shift register and is equipped with a 4-level LCD driver. The input/output pins for cascade connection can be used to further increase the IC's number of bits. The LC79431KNE can be used in conjunction with segment driver LC79401KNE (QIP100E) to drive a wide-screen LCD panel.

Features
  • On-chip LCD drive circuit (80 bits)
  • Display duty selection ranging from 1/64 to 1/256
  • On-chip input/output pins support a further increases in bit number
  • Supports externally supplied bias voltage
  • Operating power supply voltage/operating temperature include
