APD-128G032A
Vishay Dale
The APD-128G032A DC plasma display offers viewing qualities designers seek such as high contrast, viewing angle of 150°
minimum and long distance readability. Its bright (50 foot Lambert minimum) with characters and graphics figures presented
in a pleasing neon orange color against a black background. Plasma is much more readable and eye-pleasing than liquid
crystal or vacuum fluorescent displays and is filterable to red, amber or neutral density.
These plasma display panels are driven in a standard row-column refresh method much like a CRT display. The designer
need only supply TTL level signals 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 8MHz. 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 70Hz, but may be as high as 200Hz. The high clock rate on the
data clock allows for rapid refresh and maximum access time to the refresh ram.
