Unique viewing performance characteristics
Thin Film Electroluminescent (TFEL) display technology is unique and unrivaled for embedded display solutions. The combined performance and visual characteristics of TFEL displays make them superior in the most challenging and demanding applications, where other technologies simply cannot deliver. Equipment and system designers today are using TFEL displays to fulfill the increasing demands of their customers for image quality, product lifetime and reliability.
Over the last 30 years, TFEL technology has proven its excellence in applications ranging from monitor and control instruments in deep-sea vessels to operational systems in orbital spacecraft. Besides these extremes, TFEL displays have found their way into countless other applications, where uncompromised reliability and accuracy are required.
Compared with other display types on the market today, TFEL has many qualities that make it stand out:

When operating temperature is important
Lumineq TFEL displays exhibit the widest operating temperature range of any commercially available technology. The TFEL glass itself can operate down to -100 °C (-148 °F), whereas TFEL modules are rated as low as -60 °C (-76 °F) without any decrease in response time. The graph below displays the differences between TFEL and TFT. The operating temperature of a TFEL display surpasses that of both wide temperature TFTs and automotive temperature range TFTs, without losing response or clarity of view.
