128 x 32 Graphics Display with Drive Electronics and + 5 V HC CMOS Level Video Interface
FEATURES
LED replacement for the popular APD-128G032

The LEE-128G032A 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-128G032A 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-128G032A 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 sig
nal 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.
