NL8060AC26-52D: 10.4" SVGA TFT with Serviceable Backlight for Industrial Longevity
Introduction to a Display Engineered for Uptime
This 10.4-inch SVGA display is engineered for maximum uptime in demanding Human-Machine Interface (HMI) applications, offering exceptional long-term serviceability through its field-replaceable backlight system. Featuring core specifications of 800x600 SVGA | 400 cd/m² Luminance | -10°C to +70°C Operating Temperature, the NEC NL8060AC26-52D delivers two critical engineering benefits: it extends the operational life of host equipment and dramatically simplifies field maintenance. It directly addresses the primary failure point in long-service industrial displays—backlight degradation—by allowing for lamp replacement without needing to replace the entire TFT panel. For industrial control systems requiring a service life that can exceed a decade, the NL8060AC26-52D's replaceable backlight makes it a superior long-term investment.
Application Scenarios & Value
Maximizing Uptime and Lowering TCO in System Upgrades
The NL8060AC26-52D is an optimal display solution for upgrading legacy industrial control panels and process automation systems. In these environments, engineers often face the challenge of sourcing a modern, reliable display that fits an existing mechanical enclosure while providing a clear path for future maintenance. Its standard 10.4-inch form factor and industry-standard LVDS Interface simplify both mechanical and electrical integration with contemporary single-board computers or a Programmable Logic Controller (PLC) system.
The defining value proposition lies in its contribution to a lower Total Cost of Ownership (TCO). For a machine or system intended to operate for 15-20 years, a typical display's backlight may dim significantly after 50,000 hours. With the NL8060AC26-52D, this is not a terminal event. The ability to swap the backlight in the field mitigates the significant cost and downtime associated with sourcing and qualifying a completely new HMI, ensuring continuity of operations and predictable maintenance budgets. For applications requiring higher resolution within a similar form factor, the related NL10276AC30-42D offers an XGA (1024x768) resolution.
Key Parameter Overview
A Functional Breakdown for System Integration
The specifications of the NL8060AC26-52D are tailored for performance and reliability in industrial settings. Each parameter contributes to its suitability for integration into robust, long-life systems. What is the primary benefit of its design? Enhanced long-term reliability by decoupling backlight life from the panel itself.
| Feature Category | Specification | Engineering Value & Interpretation |
|---|---|---|
| Optical Performance | 10.4" Diagonal, 800 (RGB) x 600 (SVGA) | Provides a standard resolution suitable for clear visualization of SCADA interfaces, process diagrams, and equipment status without requiring high-end graphics processing. |
| Luminance & Contrast | 400 cd/m² (Typical) | Delivers bright, legible images in typical indoor industrial and factory floor environments with variable ambient lighting. A higher luminance ensures data remains readable, reducing operator error. |
| Viewing Angles | 80°/80° (L/R), 80°/60° (U/D) (Typical) | Wide viewing angles ensure that data is accurately readable from various operator positions, a critical feature for large machinery or control rooms where the HMI is not viewed head-on. |
| Electrical Interface | 1ch, 6-bit LVDS | A robust, low-EMI interface that simplifies connection to a wide range of embedded and industrial controllers, reducing design complexity and cabling requirements. |
| Environmental Resilience | Operating Temp: -10°C to +70°C; Storage Temp: -20°C to +80°C | This wide operating range allows for deployment in unconditioned environments, such as factory floors or sheltered outdoor kiosks, without requiring complex and costly thermal management hardware. |
| Serviceability | Replaceable White LED Backlight System | The core feature for long-term reliability. It allows for simple, low-cost field servicing to restore original brightness, effectively doubling or tripling the useful life of the HMI unit. |

Technical Deep Dive
A Closer Look at the Replaceable Backlight Design for Long-Term Reliability
The concept of a replaceable backlight is a strategic design choice by NEC that directly confronts the issue of planned obsolescence in industrial displays. The backlight is the component with the most predictable wear-out mechanism; LEDs lose their luminosity over thousands of hours of operation. In a conventional display, this dimming signifies the end-of-life for the entire unit. For a system with a required operational life of over 100,000 hours, this is a significant design constraint.
The NL8060AC26-52D's architecture externalizes the backlight connection, allowing a trained technician to replace the light source without disturbing the delicate LCD glass and driver electronics. This is analogous to changing a fuse rather than replacing an entire power supply. This design not only extends the product's functional lifespan but also simplifies logistics for maintenance teams, who can stock a small, low-cost component instead of an expensive, full display assembly. This feature is particularly critical for systems that require lengthy and expensive re-certification if a major component like the HMI is changed, making a simple repair far more desirable than a replacement.
Frequently Asked Questions (FAQ) for Engineers
Technical Clarifications for Design and Implementation
What is the primary engineering advantage of the replaceable backlight on the NL8060AC26-52D?
Its key advantage is the decoupling of the backlight's lifecycle from the LCD panel itself. This dramatically reduces the long-term total cost of ownership by transforming what is typically a capital replacement into a simple maintenance task. This is invaluable for systems deployed in remote locations or critical infrastructure where uptime is the highest priority.
How does the wide -10°C to +70°C operating temperature range impact the mechanical design of an HMI enclosure?
This wide range directly simplifies enclosure design and improves overall system reliability. It reduces or eliminates the need for dedicated heating or active cooling components (like fans or Peltier coolers) in many control panel applications. This not only lowers the bill of materials and power consumption but also removes common points of mechanical failure, leading to a more robust and maintenance-free final product.
