High-Brightness LED Display Modules from Vishay

By Mike PecoraroNovember 8, 2016

A popular member of Vishay’s portfolio of LED display modules, high-brightness LEE-128G032-1 was initially launched as a replacement of its popular APD-128G032 plasma display. Showcasing superior display characteristics for low to medium-level information content applications, Vishay's high-brightness LEE-128G032-1 LED finds application in arcade games, POS terminals, process control, message centers, medical equipment, and ATM machines.

The compact LEE-128G032-1 display module integrates 128 x 32 Graphics Display LLED with Drive Electronics and (+) 5-V HC CMOS Level Video Interface in an ultra-slim package.  The cutting-edge LED displays offer long distance readability, high contrast, and a wide viewing angle while radiating a brilliant orange color that’s eye-catching but is also comfortable to the viewer’s eye.

Key Features of Vishay’s High-Brightness LEE-128G032-1 LED Display Modules

Featuring a video type interface, the LEE-128G032-1 module is driven in a standard row/column refresh method. Pixel data is clocked for a row, and thereafter the rows are scanned sequentially. Signals are presented for dot clock, serial data, row data, row clock, column latch, and display enable.

The serial data is registered with the dot clock up to frequencies that might be 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. Just at the time of data latching, the display is briefly paused for a moment using the display enable signal, following which the row pointer is advanced with the row clock signal.

For each frame, the ROW DATA is synchronized with the column serial data at the beginning row. The suggested scanning frequency is approximately 70 Hz but can go as high as up to 200 Hz.
