Electroluminescent Rugged Industrial Displays – Electroluminescent Displays from Lumineq are perfect for industrial applications. They are extremely rugged with super wide operating temperatures, designed to cope with vibrations and harsh environments. We also have a range of Transparent EL displays also, perfect for scopes, windshield displays and use in industrial vehicles. EL Displays are also very popular for Military Applications where reliability and high visibility are crucial.

Lumineq® Thin Film Electroluminescent (TFEL) displays are unique and unrivalled for embedded display solutions. The combined performance and visual characteristics of TFEL displays make them superior for image quality, product lifetime and reliability in the most challenging and demanding applications. Lumineq displays tolerate cold, pressure, shock and vibrations better than any other display type. They offer excellent readability, long product life and long-term availability for a wide range of demanding applications – on land, at sea and in the air.

Electroluminescent Rugged Industrial Displays – Over the last 35 years, TFEL technology has proven its excellence in applications including monitor and control instruments in deep-sea vessels to operational systems in orbital spacecraft, together with countless other applications requiring uncompromised reliability and accuracy. Beneq Products OY has acquired the electroluminescence business of Planar Systems, and now sells these leading thin film electroluminescent (TFEL) displays under the brand name Lumineq. LUMINEQ, renowned for its ultra-reliable rugged displays, has been innovating new display technology since 1984 and developed the world’s most transparent displays in recent years. LUMINEQ transparent displays improve situational awareness of optical devices and vehicle safety by bringing dynamic information to the line of sight. They also empower automotive manufacturers to deliver premium travel experience by turning vehicle windows into touch displays.


Thin Film Electroluminescent Displays, TFEL



Lumineq® embedded TFEL displays are rugged and reliable more than suited for applications in extreme environments including retail and industrial, aerospace, mining, military and marine.

EL displays are built for demanding conditions including cold, heat, wind, dust, vibration, sunlight and even G-Forces.  These electroluminescent panels retain more than 75% of their original brightness after more than 100,000 hours of operation, making them ideal for a long term design.

The technology offers unparalleled image quality in a wide range of challenging visual conditions and TFEL_230pxapplications.  The rugged nature of electroluminescent means that the displays can work between -40 ~ +80 degrees.  The panels offer high brightness and contrast with a wide viewing angle of >160 degrees.  Fast response time, small package sizes and low EMI emissions with reduced power consumption which means EL is the perfect choice.

Their durability and ruggedness is proven by their extreme operating temperature ranges, high brightness and contrast, high shock resistance, their ability to surviving up to 200 g-force shock and a staggering 250,000-hour mean time between failures (MTBF) for the display glass. TFEL displays are capable of instant-on performance from -60 °C to +105 °C (from -76 °F to +221 °F), with instant pixel response over the entire temperature range, and no motion blur.

Electromagnetic compatibility: Lumineq TFEL displays support the end product in complying with FCC Part 15, Subpart J, Class B and EN55022, Level B, when housed in a suitable enclosure.

Electroluminescent Rugged Industrial Displays – 20 Reasons Why TFEL Is Your Most Reliable Display Choice for Extreme Conditions

If you are still not convinced on how reliable and rugged these displays really are, then here is a list of 20 reasons as to why the TFEL is perfect for extreme conditions:

1. “Instant on” module performance as low as -60 °C (-76 °F) means no waiting for heaters to warm a TFT AMLCD.

2. No heaters required with TFEL means increased product reliability and no image smear artifacts common with TFT AMLCDs used at low temperatures. Glass is functional down to -100 °C (-148 °F).

3. Less than 1 ms response time for waveform presentation across entire temperature range.

4. Unaffected by solar loading, glass performs beyond +100 °C (212 °F).

5. +85 °C (185 °F) module operating temp, no cooling required, thus increasing reliability.

6. TFEL glass has 250,000 (h) MTBF, to reduce your product’s warranty costs.

7. 100,000 h measured brightness with less than 15% reduction. Compare to TFT AMLCD technology that can lose 15% brightness in a single year.

8. Hermetically sealed glass and optional conformal coated circuit board outlasts all other flat panel technologies in moist or humid environments.

9. Battery power requirements comparable to backlit TFT LCD.

10. Integral Contrast Enhancement, ICEBrite™, delivers up to 1000:1 contrast ratio for daylight readability. Eliminates cost, time and hassle of bonding a TFT AMLCD for improved contrast.

11. Crisp, single- or multicolor presentation decreases viewing time requirements to facilitate faster user perception. Ideal for healthcare, vehicle, and mission critical instrumentation.

12. 179° vertical and horizontal viewing angles enable multi-person, off-axis viewing.

13. Wide dimming range, doesn’t require an expensive, custom backlight inverter like TFT AMLCD.

14. Emissive pixel technology makes small text more legible than LCDs, thus greatly improving perception.

15. 200 g force shock durability for the glass and 100 g for the complete unit increases the dependability of your product.

16. All solid-state, digital design eliminates backlight failures and light leakage issues common for LCDs.

17. LCD compatible interface for easier integration.

18. Over 30 years of product life and still going strong! Long production lifetime helps you avoid redesigns triggered by component obsolescence.

19. RoHS II for worldwide compliance. Mercury-free product is better for the environment. Low EMI/EMC to ease certification of your product.

20. Worldwide and domestic technical support team.
