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.
