The NL6448BC20-35D is a model that has been discontinued for many years. It is very difficult to find brand new original units on the open market; typically, only stock-clearing or refurbished units are available. As an alternative, you can look for other brands of 6.5-inch VGA displays, but pay close attention to interface compatibility (modern ones mostly use LVDS) and mechanical dimensions. Alternatively, upgrading to a 6.5-inch LED-backlit display with a higher resolution (e.g., 800x480) would be a more modern and energy-efficient choice.

Due to its industrial-grade design and VGA resolution, it was commonly used in early industrial control systems, medical instruments, test and measurement equipment, POS terminals, Human Machine Interfaces (HMI), and various professional embedded systems.

This display uses a CCFL (Cold Cathode Fluorescent Lamp) backlight. The typical lifespan of a CCFL backlight ranges from 20,000 to 50,000 hours, depending on the operating environment and temperature. As CCFL technology has been largely superseded by LED backlights, replacement may require sourcing specialized spare parts or considering a replacement of the entire module

No, the NL6448BC20-35D does not use an LVDS interface. It employs an earlier digital RGB interface, specifically an 18-bit single-pixel TTL interface. To connect it to a modern motherboard or controller, a dedicated TTL to LVDS (or other format) converter board is typically required.

The NL6448BC20-35D is a 6.5-inch TFT LCD display produced by NEC of Japan. Its key specifications include: a resolution of 640x480 pixels (VGA), a brightness of 600 cd/m², a contrast ratio of 500:1, and it uses a CCFL backlight. It is an industrial-grade display known for its high reliability and stability.
