Description
This sunlight viewable 5 x 7
LED four-character display is
contained in 12 pin dual-in-line
packages designed for
displaying alphanumeric
information. The display is
designed with on-board CMOS
integrated circuits. Two CMOS
ICs form an on-board 28-bit
serial-in/parallel-out shift
register with constant current
output LED row drivers.
Decoded column data is clocked
into the on-board shift register
for each refresh cycle. Full
character display is achieved
with external column strobing.
