HD44105 Datasheet Dot Matrix Liquid Crystal Graphic Display Common Driver

Manufacturer: Hitachi Semiconductor (now Renesas)

Overview: HD44105 (Dot Matrix Liquid Crystal Graphic Display mon Driver).

General Description

The HD44105 is a mon signal driver for LCD dot matrix graphic display systems.

It generates the timing signals required for display with its internal oscillator and supplies them to the column driver (HD44102) to control display, also automatically scanning the mon signals of the liquid crystal according to the display duty cycle.

It can select 7 types of display duty cycle 1/8, 1/12, 1/16, 1/24, 1/32, 1/48, and 1/64.

Key Features

  • Dot matrix graphic display common driver including the timing generation circuit.
  • Internal oscillator (oscillation frequency is selectable by attaching an oscillation resistor and an oscillation capacitor).
  • Generates display timing signals.
  • 32-bit bidirectional shift register for generating common signals.
  • 32 liquid crystal driver circuits with low impedance.
