LED Display Modules

128 x 32 Graphics Display with Drive Electronics and + 5 V HC CMOS Level Video Interface

Blue LED Modules, Normal Brightness, Single Board Construction, RoHS-Compliant

The LEE-128G032B-2 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-2 LED display offers high contrast,

wide viewing angle, and long distance readability. It emits a

bright blue color which catches the attention of the viewer,

but is yet comfortable to the eye.

The LEE-128G032B-2 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.
