HD61103A
(Dot Matrix Liquid Crystal Graphic Display
64-Channel Common Driver)
Description
Features
The HD61103A is a common signal driver for dot
matrix liquid crystal graphic display systems. It
generates the timing signals (switch signal to
convert LCD waveform to AC, frame synchronous
signal) and supplies them to the column driver to
control display. It provides 64 driver output lines
and the impedance is low enough to drive a large
screen.
• Dot matrix liquid crystal graphic display common driver with low impedance
• Low impedance: 1.5 kΩ max
• Internal liquid crystal display driver circuit: 64
circuits
• Internal dynamic display timing generator
circuit
• Selectable display duty ratio factor 1/48, 1/64,
1/96, 1/128
• Can be used as a column driver transferring data
serially
• Low power dissipation: During display: 5 mW
• Power supplies:
— VCC: +5 V ± 10%
— VEE: 0 to –11.5 V
• LCD driver level: 17.0 V max
• CMOS process
As the HD61103A is produced by a CMOS
process, it is fit for use in portable battery drive
equipments utilizing the liquid crystal display’s
low power consumption. The user can easily
construct a dot matrix liquid crystal graphic
display system by combining the HD61103A and
the column (segment) driver HD61102.
