HD44103
(Dot Matrix Liquid Crystal Graphic Display 20-Channel Common Driver)
Description
The HD44103 is a common signal driver for dot matrix liquid crystal 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 common signals of the liquid crystal according to the display duty. It can select 5 types of display duty ratio: 1/8, 1/12, 1/16, 1/24, and 1/32. 20 driver output lines are provided, and the impedance is low (500 Ω max.) to enable a large screen to be driven.
