Component Height 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. Voltage(s) Required: + 5 VDC (VCC) Power Required (Fully Lit): Typ. = 5.5 W, max. = 6.5 W 4.625 4.925 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. ELECTRICAL SPECIFICATIONS 0.150 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. • LED replacement for the popular APD-128G032 plasma display module • + 5 V HC CMOS level video interface • Large characters • Highly visible for long distance viewing • > 30:1 contrast ratio • Bright red color • Slim profile • Reduced power and brightness version • Material categorization: For definitions of compliance please see www.vishay.com/doc?99912 0.062 Pin 1 of J1 Pin 1 of J2 Document Number: 37088 1 For technical questions, contact: [email protected] THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE.

A total of 128 dot clock transitions must be present for each line of column/anode data. Serial data - This signal presents the pixel data in positive logic format. A logic one represents a lit pixel and a logic zero represents an extinguished pixel. Data is entered from right to left. The first pixel data entered will represent the left most pixel in the row. Column latch - This signal latches the pixel data into the driver outputs. When the column latch signal goes to logic one the data entered previously will fall through to the driver outputs. When the signal returns to a logic zero the data is latched and the shift register is now ready to accept the next row of data. Must be held low while entering new serial data. Display enable - This signal enables the output drivers. Using a duty cycle control, this signal may also be used for intensity control. The display enable must be at logic zero before the column latch signal transitions. To avoid display blurring, the row clock signal should also transition while display enable is a logic zero. Row data - This signal is the first line marker for the scan. This input should be held high to correspond to the first row of pixel data. Row clock - This signal clocks row data on the falling edge. The row clock signal is repetitive and must be present for proper scanning of the display module. The LEE-128G032B has an unique input protection circuit that assures the column drivers stay blanked on power up. The protection circuit unblanks the column drivers when the row clock signal begins (i.e the display begins scanning).
