LTA104A261F: Industrial 10.4-inch VGA TFT-LCD Module Engineered for Longevity and Clear Readability
The Toshiba LTA104A261F is a 10.4-inch a-Si TFT-LCD module designed for sustained performance in industrial applications. It delivers a combination of high brightness, robust backlight lifespan, and mechanical compatibility crucial for legacy system upgrades and new designs requiring proven reliability. With its 640x480 VGA resolution, 400 cd/m² luminance, and a 50,000-hour backlight life, this display provides a durable and clear human-machine interface (HMI) solution. It directly addresses the need for long-term operational stability and clear visibility in demanding industrial environments. For systems requiring a balance of proven durability and consistent optical performance, the LTA104A261F offers a well-engineered solution.
Application Scenarios & Value
System-Level Benefits in Industrial Control and Monitoring
The LTA104A261F is engineered for applications where long-term reliability and consistent performance are non-negotiable. Its primary value is demonstrated in industrial control panels, factory automation HMIs, and specialized monitoring equipment. In these settings, a key engineering challenge is ensuring continuous, clear data presentation over a device's extended service life, often in environments with stable but constant operational demands. The module's 50,000-hour CCFL backlight rating directly addresses this challenge. This specification is not merely a number; it translates to over 5.7 years of continuous 24/7 operation before the backlight reaches half its initial brightness, significantly reducing maintenance cycles and total cost of ownership compared to displays with shorter-lived backlights. The 400 cd/m² brightness ensures that information is clearly legible under typical indoor industrial lighting conditions, preventing operator error and improving efficiency. While this model is a robust solution for VGA systems, for applications demanding higher pixel density, designers might consider displays like the NL10276AC30-42D.

Technical Deep Dive
Understanding the Value of Backlight Longevity and Serviceability
A critical, yet often overlooked, feature of the Toshiba LTA104A261F is its dual CCFL backlight system with a 50,000-hour typical lifespan. In the context of industrial equipment that may operate for a decade or more, this longevity is a cornerstone of the display's value proposition. The 50k-hour rating means the backlight is engineered to run continuously for nearly six years before its brightness degrades to 50% of the initial value. This significantly reduces the likelihood of requiring maintenance within the typical service life of the host equipment. For a system integrator or OEM, this translates to a more reliable product and a lower total cost of ownership for the end-user. Furthermore, the datasheet highlights the replaceable structure of the lamp units. This design choice provides a practical path for extending the display's operational life even further, a crucial feature for mission-critical systems where replacing the entire HMI unit would be prohibitively expensive or disruptive. This serviceability, combined with its mechanical compatibility with older models like the LTM10C210A, positions the LTA104A261F as a strategic component for both new designs and long-term product support.
Frequently Asked Questions (FAQ)
What is the primary benefit of the 50,000-hour backlight life?
Its primary benefit is enhanced long-term reliability and a lower total cost of ownership by minimizing the need for maintenance or replacement over the lifespan of the host industrial equipment.
Is the LTA104A261F suitable for outdoor applications?
With an operating temperature range of 0 to 50°C and a brightness of 400 nits, this display is optimized for indoor industrial environments. It is not designed for direct sunlight exposure or extreme temperature ranges found in outdoor applications.
How does the 250:1 contrast ratio impact usability in an industrial setting?
A 250:1 contrast ratio provides clear differentiation between colors and shades, ensuring that graphical user interfaces, text, and numerical data on HMIs are distinct and easily readable under controlled, indoor factory lighting.
What does "mechanical compatibility with LTM10C210A" mean for system upgrades?
It means the LTA104A261F has similar physical dimensions and mounting points, allowing it to serve as a drop-in replacement for the older LTM10C210A model in existing systems, simplifying repairs and upgrades with minimal re-engineering.
