Introduction and Core Features
The PVI PD064VT4 is a robust 6.4-inch VGA TFT-LCD module engineered for stable visual performance in demanding industrial environments with wide temperature fluctuations. It delivers a proven combination of essential specifications and operational resilience, making it a strong candidate for long-lifecycle equipment. Key specifications include: 6.4” Diagonal | 640x480 VGA Resolution | -10 to +70°C Operating Temperature. The primary engineering benefits are its exceptional thermal tolerance and a standard 4:3 aspect ratio ideal for legacy system upgrades. Its wide operating temperature range directly addresses the need for consistent performance in uncontrolled settings, such as factory floors or outdoor kiosks, ensuring reliable operation without auxiliary heating or cooling.
Intra-Series Comparison & Positioning
Positioning the PD064VT4: A Focus on Legacy System Compatibility
In a market often dominated by widescreen formats, the PD064VT4 occupies a critical niche. Its 4:3 aspect ratio and 640x480 VGA resolution make it an ideal form, fit, and function candidate for retrofitting or maintaining existing industrial control panels, medical devices, and test equipment. Many legacy systems were designed around this specific screen geometry, and upgrading to a widescreen display can require costly and complex redevelopment of the user interface software and mechanical housing. The PD064VT4 provides a direct pathway to extend the service life of valuable capital equipment, avoiding the significant non-recurring engineering costs associated with a complete system redesign. It stands as a pragmatic choice for applications where stability, compatibility, and long-term availability are prioritized over the latest display trends.
Key Parameter Overview
Technical Specifications for Demanding Conditions
The performance of the PD064VT4 is defined by specifications chosen for industrial utility. These parameters provide a clear framework for system integration and performance evaluation. For engineers designing systems for challenging environments, understanding the environmental resilience ratings is a critical first step.
One of the most crucial parameters is the Operating Temperature Range of -10°C to +70°C. This specification is not merely a number; it is a declaration of the component's operational envelope. Think of it like the operating pressure range of a hydraulic system; exceeding it risks immediate and potentially permanent failure. This wide range ensures that the display can start up reliably in cold conditions and maintain stable optical characteristics, like contrast and response time, during periods of high ambient heat without forced air cooling in many scenarios.
Another key feature, the Anti-Glare Surface Treatment, directly impacts usability in real-world industrial settings. This treatment diffuses ambient light, reducing specular reflections from overhead lighting or indirect sunlight that could otherwise wash out the screen image. This enhances readability and reduces operator eye strain and potential errors, a critical factor for human-machine interfaces (HMIs).

Application Scenarios & Value
Engineered for Environments Where Reliability is Paramount
The PD064VT4's feature set is tailored for applications where operational uptime and clear data presentation are fundamental. Its design integrity supports deployment across several key sectors:
- Industrial Automation: Ideal for integration into Programmable Logic Controller (PLC) interfaces, machine control panels, and process monitoring stations on the factory floor, where temperature is often unregulated.
- Test and Measurement Equipment: Provides a clear, reliable display for portable or benchtop instruments like oscilloscopes, spectrum analyzers, and network testers used in field service or production line quality control.
- Medical Devices: Suitable for patient monitoring systems, diagnostic equipment, and medical instrumentation that require a proven, stable display component with a long product lifecycle. For devices requiring higher resolution in a similar size, the AA065VD01 offers an alternative feature set for evaluation.
- Transportation and Kiosks: The display's temperature range and anti-glare surface make it a viable option for driver information displays, ticketing machines, and public information terminals.
What is the primary benefit of its robust build? It enables consistent system operation across a wide thermal spectrum, reducing failure risk. For legacy industrial systems requiring a 4:3 VGA display with proven thermal resilience, the PD064VT4 is a mechanically and electrically compatible solution.
Industry Insights & Strategic Advantage
The Strategic Value of Long-Lifecycle Components in Industrial Automation
In the industrial sector, the Total Cost of Ownership (TCO) often outweighs the initial component price. Frequent product updates, common in consumer electronics, represent a significant burden for industrial OEMs who face expensive and time-consuming system re-qualification and certification processes. The PD064VT4 embodies the principle of product stability. By selecting a mature component like this, engineers can design systems with a multi-year production and service life in mind. This strategy mitigates supply chain risks associated with short-lifecycle parts and ensures that replacement spares are available for field service, maximizing the operational uptime and return on investment for the end-user's capital equipment. This focus on stability is a cornerstone of effective industrial versus consumer display selection.
Technical Deep Dive
A Closer Look at the Display's Construction
The PD064VT4 is built upon a foundation of established and reliable TFT-LCD technology. The display utilizes an amorphous Silicon (a-Si) Thin-Film Transistor structure, a technology known for its maturity and cost-effectiveness in manufacturing. The heart of its illumination system is a single Cold Cathode Fluorescent Lamp (CCFL) backlight. While modern displays often use LED backlights, the CCFL in this module is a well-understood technology with predictable performance and a known operational lifespan, a crucial factor for industrial maintenance schedules. The light from this CCFL is distributed evenly across the screen by a series of diffuser and prism films, ensuring the specified 250 cd/m² luminance is achieved with good uniformity. The display's data is delivered via a parallel TTL RGB interface, a straightforward and robust electrical connection common in industrial embedded systems, simplifying the driver board design and reducing potential EMI issues compared to high-speed serial interfaces.
