EL320.240-FA3 multi-color QVGA display 

The EL320.240-FA3 thin film electroluminescent (TFEL) multi-color display is a high-
performance alternative to QVGA (320 x 240) LCDs and the ideal solution in demanding 
applications where superior visual performance, extreme temperature range, and 
environmental ruggedness are critical. 

The EL320.240-FA3 utilizes Lumineq

®

 Displays’ proprietary Integral Contrast Enhancement 

(ICEBrite™) technology combined with red and green filters patterned over Lumineq Displays’ 
industry-leading yellow phosphor to achieve unparalleled image quality in hues of red, green 
and yellow. Three intensity levels in each of the red and green sub-pixels generate 16 distinct 
colors (9 chromatically different colors, black, and 2 mid-levels of red, green, and yellow.) 

The display consists of a solid state TFEL glass panel, depicted below, with a 124 mm 
diagonal active area, and control electronics assembled into a space-saving, rugged package 
for easy mounting.

Features and benefits 

 

Excellent visual performance: 

 

Unparalleled crisp, clear image 

 

Excellent contrast 

 

Unbeatable viewing angle of > 179° for all colors in all directions 

 

No off-axis color or contrast shift 

 

Extremely wide operation temperature range: -50˚C to 85 °C 

 

Instant turn on at -50 °C: no heaters needed, no warm up time 

 

Long life phosphor: allows >11 years of continuous operation 

 

Wide dimming range via digital control and analog voltage input 

 

Rugged solid state construction 

 

Great reliability: MTBF > 50,000 hours demonstrated 

 

Low cost of ownership: no maintenance, no lamps to replace 

 

AMLCD-type panel interface, 3 V and 5 V logic compatible 

 

RoHS compliance
