HDLX-1414 Series
Four Character Smart Alphanumeric Displays
Data Sheet
Description
These are 3.7 mm (0.145 inch) four character 5 x 7 dot matrix
displays driven by an on-board CMOS IC. These displays are
pin for pin compatible with the HPDL-1414.The IC stores and
decodes 7-bit ASCII data and displays it in an easy to read
5 x 7 font. Multiplexing and LED drive circuitry is also
included in the display, and fast setup and hold times
allow it to interface easily with common microprocessors.
The address and data inputs can be directly connected to
microprocessor address and data buses.
The HDLX-1414 offers a larger character set than the
HPDL-1414. Lower case letters and special symbols
are now offered, made possible by the 5 x 7 dot matrix
character layout.
The difference between the sunlight viewable HDLS-1414
and the low power HDLU-1414 lies in the brightness level.
The sunlight viewable version is internally set to provide
high intensity characters. The low power version uses
the same bright LED technology, but reduces the current
through each LED to a much lower level, and maintains an
intensity comparable to the HDLO-1414.
