EL320.256-FD7 Operations Manual (020-0353-00A) 

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.
