Content last revised on October 20, 2025.
Introduction to a Mission-Ready Display
The EL640.480-AG1 is an 8.1-inch TFEL display engineered for absolute reliability in applications where conventional displays fail. With its core specifications of 640x480 VGA |
Key Parameter Overview
Decoding the Specs for Environmental Resilience
The technical specifications of the EL640.480-AG1 underscore its suitability for extreme conditions. Unlike liquid crystal-based displays that suffer from performance degradation at temperature extremes, this Thin Film Electroluminescent (TFEL) panel maintains consistent brightness, contrast, and response time across its entire operating range. The sub-millisecond response time is particularly critical in applications like avionics and industrial automation, where instantaneous data updates are essential for operator control and safety.
| Parameter | Specification | Engineering Value |
|---|---|---|
| Display Technology | Thin Film Electroluminescence (TFEL) | Solid-state design provides intrinsic resistance to shock (100 g), vibration, and humidity. |
| Resolution | 640 x 480 (VGA) | Standard resolution ensures compatibility with a wide range of industrial video controllers. |
| Active Area | 165.1 x 123.8 mm | Provides a clear 8.1-inch diagonal viewing area for critical data visualization. |
| Luminance | 55 cd/m² (Typical @ 120 Hz) | Delivers clear, readable imagery for indoor and shaded outdoor environments. |
| Response Time | < 1 ms | Eliminates motion blur and ghosting, crucial for displaying rapidly changing data. |
| Viewing Angle | > 179° | Allows for accurate off-axis viewing from virtually any direction without color or contrast shift. |
| Operating Temperature | -5°C to +55°C (Standard) / -40°C to +85°C (ET Model) | Ensures immediate, reliable operation in environments from cold storage to desert heat without heaters. |
| MTBF | > 50,000 hours | Indicates a long operational life, reducing total cost of ownership in long-term deployments. |

Application Scenarios & Value
System-Level Benefits in High-Stress Environments
The true value of the EL640.480-AG1 is realized in applications where failure is not an option. Consider the human-machine interface (HMI) on heavy construction equipment or in an aircraft cockpit. These environments are characterized by extreme temperature swings, constant vibration, and high shock loads. A standard LCD panel's liquid crystals would slow down in the cold, causing severe ghosting, and could be damaged by sustained vibration. The EL640.480-AG1's solid-state TFEL technology completely bypasses these failure modes. Its ability to turn on instantly at -40°C without a heater simplifies system design, reduces power consumption, and eliminates a common point of failure. This inherent ruggedness makes it a prime candidate for avionics, military ground vehicles, marine systems, and industrial automation control panels where data must be clearly legible 100% of the time. For applications that require a different form factor but similar ruggedness, the LB064V02-B1 may be a suitable consideration.
