EL640.200-U2 | Rugged TFEL Display for Extreme Environments
The EL640.200-U2 is not a standard industrial display; it is an engineering solution for applications where conventional LCDs fail. Built on Thin Film Electroluminescent (TFEL) technology, this display delivers unwavering performance in the face of extreme temperatures, severe shock, and high vibration. It is specifically designed as a long-life, form-fit replacement for legacy Planar and Sharp plasma displays, offering a modern upgrade path for critical equipment.
- Solid-State Reliability: Withstands 100g shock and harsh vibration, making it ideal for mobile, military, and heavy industrial use.
- Extreme Temperature Range: Operates flawlessly from -25°C to +65°C, environments where liquid crystals in standard industrial LCD displays would freeze or degrade.
- Exceptional Visual Performance: Features a lightning-fast <1 ms response time, eliminating all motion blur, and a >160° viewing angle for clarity from any perspective.
- ICEBrite™ Technology: Integral Contrast Enhancement ensures crisp, readable data even in challenging ambient light conditions.
The Engineering Behind TFEL: Unmatched Durability
Unlike TFT-LCD technology that relies on a liquid crystal layer and a separate backlight, the EL640.200-U2 utilizes a fundamentally more robust solid-state architecture. A phosphor layer is sandwiched between transparent dielectric layers and electrodes. When voltage is applied, the phosphor emits light directly. This emissive, self-illuminating design eradicates the most common failure points of LCDs in harsh environments. There is no liquid to freeze or leak, no backlight to fail, and no complex layers that can delaminate under G-force. The result is a display with intrinsic durability engineered at the material level.
Field-Proven Performance in Demanding Applications
The unique characteristics of the EL640.200-U2 make it the definitive choice for specific, high-stakes applications where failure is not an option. Its design solves critical engineering problems across multiple sectors.
- Legacy System Retrofits: It serves as a direct, form-fit-function replacement for aging and discontinued Sharp LJ640Uxx series and Planar EL640.200-XX plasma displays, extending the life of valuable industrial and medical equipment without costly redesigns.
- Military and Avionics: The certified resistance to shock and vibration ensures operational integrity in armored vehicles, mobile command centers, and avionics systems where reliability is paramount. This is engineering for extremes.
- Industrial Automation: In steel mills, on oil rigs, or in heavy manufacturing, the wide operating temperature and immunity to mechanical stress ensure consistent HMI performance. The ultra-wide viewing angle allows operators and maintenance crews to monitor processes safely from a distance.

Engineer's FAQ for the EL640.200-U2
Is the EL640.200-U2 a type of LCD?
No. It is a Thin Film Electroluminescent (TFEL) display, which is an emissive technology. Unlike LCDs, which are transmissive and require a backlight, each pixel in a TFEL display generates its own light. This fundamental difference is the source of its superior ruggedness and performance in extreme conditions.
Can this display directly replace a Sharp LJ640U34 plasma panel?
Yes, the EL640.200-U2 is engineered as a form-fit-function replacement for the Sharp LJ640Uxx series, including the LJ640U34. It matches the mechanical mounting points and the electrical interface, providing a seamless upgrade path that avoids expensive system redesigns. However, as with any component replacement, we recommend verifying pinouts against your system's documentation. For any integration questions, please contact our technical team.
