LED Display Modules
128 x 32 Graphics Display with Drive Electronics and + 5 V HC CMOS Level Video Interface
Red LED Modules, Normal Brightness, Single Board Construction, RoHS-Compliant
The LEE-128G032B is an LED replacement for the popular
APD-128G032 plasma display module. It is designed to
offer high brightness and superior viewing characteristics in
a slim package. This display is ideal for low to medium level
information content and is ideal for applications such as
arcade games, process control, POS terminals, medical
equipment, message centers and ATM machines.
The LEE-128G032B LED display offers high contrast, wide
viewing angle, and long distance readability. It emits a bright
red color which catches the attention of the viewer, but is yet
comfortable to the eye.
The LEE-128G032B LED display has a video type interface
and is driven in a standard row/column refresh method.
Pixel data is clocked for a row, and rows are scanned
sequentially. Signals are presented for serial data, dot clock,
column latch, row data, row clock and display enable. The
serial data is entered with the dot clock up to frequencies as
high as 8 MHz. After a row of 128 pixels is clocked in, the
column latch signal is toggled and the data is latched. At the
time the data is latched, the display is briefly disabled using
the display enable signal, then the row pointer is advanced
with the row clock signal. Once each frame the row data
must be asserted to synchronize the column serial data with
the beginning row. The recommended scanning frequency
is approximately 70 Hz, but may be as high as 200 Hz.
