The AA084VF05 is an 8.4-inch a-Si TFT-LCD module from Mitsubishi, engineered for consistent performance in demanding industrial applications. It delivers a clear 640 x 480 (VGA) resolution with a typical brightness of 380 cd/m² and a 600:1 contrast ratio, ensuring excellent image legibility. Its most significant engineering advantage is the exceptionally wide operating temperature range of -30°C to 80°C, which guarantees operational reliability in environments subject to extreme temperature fluctuations. For systems requiring higher resolution in a similar form factor, the AA084VC03 offers SVGA (800x600) resolution. The AA084VF05 is an optimal choice for industrial HMIs where resilience and visual clarity under harsh conditions are non-negotiable.
Key Parameter Overview
Decoding the Specs for Environmental Resilience
The technical specifications of the AA084VF05 are optimized for durability and integration into industrial systems. Its performance is anchored by its robust thermal tolerance and reliable optical characteristics.
| Category | Specification | Engineering Value |
|---|---|---|
| Display | 8.4-inch a-Si TFT-LCD | Standard size for a wide range of industrial panels and control units. |
| Resolution | 640(RGB)×480 [VGA] | Provides clear and sufficient detail for typical HMI and monitoring tasks. |
| Brightness | 380 cd/m² (Typ.) | Ensures good readability in typical indoor industrial and control room lighting. |
| Contrast Ratio | 600:1 (Typ.) | Delivers sharp differentiation between colors and shades, crucial for detailed graphical interfaces. Think of it as the difference between crisp black ink on bright white paper versus gray text on a dull page; a higher ratio means superior clarity. |
| Viewing Angle | 80°/80°/80°/60° (L/R/U/D) | Allows for clear image viewing from multiple off-axis positions, a key requirement for control panels accessed by various operators. |
| Operating Temp. | -30°C to 80°C | Guarantees operational stability in unconditioned environments, from cold storage facilities to outdoor-adjacent control boxes. |
| Storage Temp. | -30°C to 80°C | Enhances logistical flexibility and long-term reliability by withstanding extreme non-operational conditions. |
| Interface | CMOS (1 ch, 6-bit) | A widely used interface that simplifies integration with many industrial motherboards and single-board computers. |
| Backlight | CCFL, 50k hours lifetime | Provides a long operational life, reducing maintenance cycles and total cost of ownership. |
Application Scenarios & Value
System-Level Benefits in Environmentally Demanding HMIs
The AA084VF05 is engineered for applications where environmental resilience is as critical as optical performance. Its standout feature, the -30°C to 80°C operating temperature range, makes it a prime candidate for Human-Machine Interfaces (HMIs) and control panels in sectors where temperature is uncontrolled. For industrial systems demanding higher pixel density for more complex graphical data, the related AA084XA02 provides an XGA (1024x768) alternative.
Consider a mobile control unit for agricultural machinery or a panel on an outdoor conveyor system. These systems face direct sun, which can elevate internal temperatures, and cold morning starts that can challenge lesser displays. The AA084VF05's ability to perform reliably across this wide thermal spectrum eliminates the need for complex and costly external heating or cooling systems. This simplifies the mechanical design, reduces power consumption, and minimizes potential points of failure, directly contributing to a lower total cost of ownership. The 8.4-inch screen with VGA resolution provides a compact yet clear interface for critical operational data, making it a workhorse for rugged industrial automation and outdoor terminals.

Frequently Asked Questions (FAQ)
What is the primary benefit of the AA084VF05's wide temperature range?
The primary benefit is enhanced system reliability and a lower total cost of ownership. The ability to operate from -30°C to 80°C allows for deployment in harsh, unconditioned environments without requiring external heating or cooling systems, which simplifies design, reduces cost, and eliminates potential failure points.
How does the 600:1 contrast ratio impact usability in an industrial setting?
A 600:1 contrast ratio ensures that graphical elements, text, and data are sharp and distinct. In an industrial HMI, this is critical for reducing operator error, as it makes alarms, status indicators, and fine-lined schematics clearly legible, even under imperfect lighting conditions.
