NEC NL6448BC26-09 | Industrial-Grade 8.4" VGA TFT LCD for Legacy System Longevity
The NEC NL6448BC26-09 is an 8.4-inch TFT-LCD display engineered for reliability and long-term performance in demanding industrial environments. As a cornerstone for human-machine interfaces (HMI), process control systems, and medical instrumentation, this display delivers consistent visual clarity where operational uptime is non-negotiable. Its robust construction and stable performance make it an ideal choice for new designs requiring proven technology and as a drop-in replacement for sustaining legacy systems.
Engineered for Industrial Endurance
The NL6448BC26-09 isn't just a display; it's a component designed from the ground up to solve critical industrial challenges. Its feature set is a direct response to the needs of engineers designing for the factory floor, not the office desk.
- Wide Operating Temperature Range: With an operational window of -10°C to +70°C, this module performs reliably in environments where commercial-grade displays would fail, from unheated warehouses to enclosed control cabinets with significant heat buildup.
- VGA Resolution (640x480): The classic VGA format ensures broad compatibility with a vast range of industrial controllers, single-board computers, and legacy video signals, simplifying system integration and maintenance.
- High-Contrast Visuals: A 500:1 contrast ratio and 400 cd/m² brightness ensure that critical data, schematics, and control interfaces are clearly legible, reducing operator error even under challenging factory lighting.
- CCFL Backlight with Long Lifespan: The Cold Cathode Fluorescent Lamp (CCFL) backlight is recognized for its excellent color stability and a typical lifespan of 50,000 hours, ensuring consistent performance over the long operational life of the host equipment.

Frequently Asked Questions for Engineers
Our specialists often field questions about integrating displays like the NL6448BC26-09. Here are two common queries:
1. Is the CCFL backlight replaceable?
Yes, the CCFL backlight and the associated inverter are typically designed to be replaceable components. This is a crucial feature for maximizing the service life of industrial equipment, as the backlight is often the first component to degrade over tens of thousands of hours of use. We can assist in sourcing compatible replacement parts to ensure your equipment remains in service.
2. How does the LVDS interface benefit my design?
The LVDS (Low-Voltage Differential Signaling) interface is an industrial standard known for its high noise immunity and low electromagnetic interference (EMI). This is a significant advantage in electrically noisy environments common in factories. It allows for longer cable runs between the display and the controller compared to parallel interfaces, offering greater design flexibility in equipment layout. This robust interface is a hallmark of truly industrial LCD displays.
