Product Profile
The EL320.256–FD7 display is a low power, rugged, electroluminescent (TFEL)
display which replaces the bulky CRT in control and instrument product
designs. It features an integrated DC/DC converter, and its compact
dimensions save space that can allow addition of features or reduction in
overall size. It is designed to function in extreme environments, and its clear
display is viewable under most lighting conditions at wide viewing angles. Its
ease of installation reduces system integration costs.
The EL320.256-FD7 is a 320 column by 256 row flat panel display. The digital
flat panel interface is designed to match the needs of most systems.
The display re5 Vdc and +11 to +30 Vdc (Vcc1, Vcc2) power and four
basic signals to operate:
1.
Video Data or pixel information (VID)
2.
Video Clock, pixel clock, or dot clock (VCLK)
3.
Horizontal Sync (HS)
4.
Vertical Sync (VS)
EL Technology
The display consists of an electroluminescent glass panel and two mounted
circuit boards with control electronics.
Figure 1. EL Technology.
The EL glass panel is a solid-state device with a thin film luminescent layer
sandwiched between transparent dielectric layers and a matrix of row and
column electrodes. The row electrodes, in back, are aluminium; the column
electrodes, in front, are transparent. The entire thin film device is deposited on
a single glass substrate. The glass panel is mounted to an electronic circuit
assembly board (ECA) with an elastic spacer. The ECA’s are connected to the EL
glass panel with soldered lead frames. The result is a flat, compact, reliable and
rugged display device.
