Product profile 

The EL320.256-FD6 display is low-power, rugged, electroluminescent (TFEL) display. The 
display has an integral DC/DC converter and compact dimension save space that allows 
addition of features or reduction in overall size. The display is designed to function in extreme 
environments, and a crisp display is viewable under most lighting conditions at wide viewing 
angles. The display ease of installation reduces system integration costs. 

The EL320.256-FD6 is 320 columns by 256 row flat panel display with a resolution of 80 dots 
per inch. The pixel aspect ratio is 1:1. The digital flat panel interface is designed to match the 
needs of most systems. The display may be driven at frame rates up to 75 Hz. 

The EL320.256-FD6 display re5 V and +11 V to +30 V (V

TFEL technology 

The display consists of an electroluminescent glass panel and two mounted circuit boards 
with control electronics. 

 

Figure 1. TFEL technology 

The TFEL 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 aluminums; 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 ECAs are connected to 
the TFEL glass panel with soldered lead frames. The result is a flat, compact, reliable, and 
rugged display device.
