For systems that must operate reliably across extreme temperature shifts, the TX14D25VM1BAA's certified -30 to 80°C range provides a critical design advantage.
Key Parameter Overview
A Specification Breakdown for Demanding Industrial Applications
The technical specifications of the TX14D25VM1BAA are tailored for integration into systems where operational uptime and clear visual feedback are paramount. Each parameter underscores its suitability for environments that exceed the limitations of standard consumer-grade displays. The combination of its thermal resilience and extended backlight lifespan makes it a strategic component for lowering the total cost of ownership in long-deployment applications.
| Specification | Value | Engineering Value |
|---|---|---|
| Screen Size | 5.7 inches | Provides a compact yet clear viewing area suitable for space-constrained HMI panels and portable diagnostic tools. |
| Resolution | 320(RGB)×240 [QVGA] | Delivers crisp and clear imaging for essential graphical user interfaces, status indicators, and data readouts. |
| Operating Temperature | -30 to 80 °C | Ensures reliable startup and sustained operation in unconditioned environments, from cold storage facilities to sun-exposed control panels. This wide range is a key differentiator for outdoor and mobile industrial equipment. |
| Brightness | 450 cd/m² (Typ.) | Offers strong screen visibility in typical indoor industrial lighting and sufficient brightness for many outdoor shaded applications. |
| Backlight Lifetime | 50,000 hours (Typ.) | Represents over 5.7 years of continuous 24/7 operation, significantly reducing maintenance requirements and system downtime. This long-life backlight is analogous to choosing an industrial-grade engine rated for continuous duty over a standard automotive one. |
| Interface | CMOS (1 ch, 6-bit) | A widely adopted parallel interface that simplifies integration with a broad range of embedded controllers and single-board computers, accelerating the design cycle. |
| Contrast Ratio | 600:1 (Typ.) | Provides well-defined separation between blacks and whites, ensuring that text and graphical elements are sharp and easy to discern. |

Application Scenarios & Value
System-Level Benefits in Industrial HMI and Control Systems
The TX14D25VM1BAA is engineered for applications where failure is not an option. Its core value lies in its ability to deliver consistent visual performance in environments that would compromise or destroy commercial-grade displays. The defining feature for many design engineers is the exceptionally broad -30 to 80 °C operating temperature range. This capability is critical for equipment deployed outdoors or in unheated/uncooled facilities, such as agricultural vehicle consoles, remote pipeline monitoring stations, and dockside marine electronics. In these scenarios, the display must perform flawlessly from a cold start in freezing conditions to peak operational heat under direct sunlight, a challenge this module is specifically built to meet.
Furthermore, its 5.7-inch diagonal size and QVGA resolution provide an optimal balance of information density and physical footprint for Human-Machine Interfaces (HMIs) in industrial automation. It can clearly render process schematics, equipment status, and diagnostic menus without requiring a large cutout in a control panel. For developers needing a larger screen for more complex data visualization, the G070ACE-L01 offers a 7.0-inch alternative, while applications requiring a different form factor might consider the AA057QD01. The robust build and reliable components ensure that the operator's primary point of interaction with the machinery remains dependable for years, supported by a backlight rated for 50,000 hours of service.
Frequently Asked Questions
Engineering Inquiries on Integration and Long-Term Performance
What is the primary benefit of the -30 to 80°C operating temperature?
Its primary benefit is guaranteed performance and reliability in thermally unregulated environments, eliminating the need for costly external heating or cooling systems for the display itself. This makes it ideal for outdoor terminals, vehicle-mounted systems, and industrial shop floors.
How does the 50,000-hour backlight lifetime translate to real-world system maintenance?
A 50,000-hour lifetime equates to approximately 5.7 years of continuous, 24/7 operation. For a system running 8 hours a day, this extends to over 17 years. This significantly reduces total cost of ownership by minimizing the need for backlight replacement, a common failure point in lesser displays.
Is the CMOS interface suitable for modern embedded systems?
Yes, the 6-bit parallel RGB CMOS interface is a mature and stable standard supported by a vast number of microcontrollers and system-on-chips (SoCs) used in industrial and medical fields. Its straightforward nature simplifies driver development and hardware integration compared to more complex serial interfaces.
Can this display be read in direct sunlight?
With a typical brightness of 450 nits, the TX14D25VM1BAA is highly readable in indoor and well-shaded outdoor conditions. For direct, full-sunlight applications, additional measures such as optical bonding or integration behind a custom-designed anti-reflective shield may be necessary to achieve optimal clarity. You can learn more about this in our guide to sunlight readable HMIs.
What does the "Normally White" TN display type imply for my application?
"Normally White" means that if the display loses power or a pixel fails, the pixel will appear white. This can be a desirable characteristic in certain applications, such as medical imaging or avionic displays, where a failed-dark pixel could obscure critical underlying information.

Deep Dive: Deploying the TX14D25VM1BAA in an Outdoor Process Control Terminal
Consider the engineering challenge of designing an HMI for a water treatment facility's outdoor control station. The terminal is exposed to seasonal temperature swings from -20°C in the winter to over 40°C under summer sun, with internal enclosure temperatures rising even higher. A standard commercial display would likely fail at these extremes, suffering from slow response times, crystallization of the liquid crystal at low temperatures, or permanent damage from heat.
The TX14D25VM1BAA directly solves this problem. Its certified -30 to 80 °C operating range provides more than enough thermal margin to ensure reliable operation year-round without auxiliary climate control. An engineer can design with confidence, knowing the display will power on and provide a clear, responsive image whether the operator is performing a system check during a snowstorm or under the midday sun. The 450-nit brightness, coupled with a proper anti-glare enclosure faceplate, ensures critical process data remains legible. This inherent robustness simplifies the mechanical and thermal design of the overall enclosure, reducing system complexity, cost, and potential points of failure.
From a design perspective, the selection of a component like the TX14D25VM1BAA is a strategic decision that prioritizes long-term system reliability over initial component cost. Its robust specifications are not just numbers on a datasheet; they are engineering assurances that translate directly into reduced field service calls, increased equipment uptime, and a more resilient final product. For engineers building systems that must operate without fail in demanding conditions, this display provides a solid and dependable foundation for the visual interface.
