NL6448BC33-54 NEC 10.4 inch 640*480 lcd display panel
NL6448BC33-54 NEC 10.4 inch 640*480 lcd display panel
The NEC NL6448BC33-54 is a 10.4-inch active matrix TFT-LCD display module with a resolution of 640 × 480 pixels (VGA). It features a transmissive display mode with normally white operation. The active area measures approximately 211.2×158.4 mm (H×V) with overall outline dimensions of roughly 243×185.1×11 mm (H×V×D). The panel supports 31-bit parallel CMOS interface (6 bits per color), capable of displaying up to 262,144 colors. Logic power supply is 3.3V or 5.0V (selectable), with typical power consumption around 2.5W to 4.0W (excluding backlight). The module utilizes dual CCFL (Cold Cathode Fluorescent Lamp) backlighting, requiring an external inverter with typical lamp current of 6.0 mA and lamp voltage of approximately 600 Vrms to 700 Vrms. Operating temperature range is -10°C to +70°C (some variants support -20°C to +70°C), with a storage range of -20°C to +80°C. The module typically features a 31-pin connector for signal interface.
NL6448BC33-54 NEC lcd display panel Key Highlights:
Exceptional image quality – Delivers high contrast ratio (typically350:1) , high brightness (approximately 220cd/m²) , and wide viewing angles (typically 45/45/30/20 (Typ.)(CR≥10)), making it ideal for medical imaging, industrial automation, and professional broadcast monitors.
NEC's renowned reliability – Built to industrial-grade standards, this panel offers superior long-term stability, excellent vibration and shock resistance, and a mean time between failures (MTBF) of over 50,000 hours for mission-critical applications.
Flexible power compatibility – Dual-voltage logic (3.3V/5.0V selectable) and standard 18-bit CMOS interface allow seamless integration with both legacy and modern controller systems without voltage level shifting.
Proven 10.4-inch VGA format – The 640×480 resolution on a 10.4-inch diagonal provides a comfortable, highly readable display size for operator terminals, test equipment, medical patient monitors, and marine electronics.
Dual CCFL backlight – Provides excellent brightness uniformity and long backlight lifetime (typically 50,000 to 80,000 hours to half-brightness) , suitable for 24/7 continuous operation environments.
Long product life cycle – NEC (now part of Sharp/NLT Technologies) supports this model with extended production runs, making it a trusted choice for defense, aerospace, and medical device manufacturers requiring long-term availability.

FAQ:
How are the viewing angles for this 10.4" NEC screen? Does it have color shifting when viewed from the side?
The NL6448BC33-54 utilizes NEC's TN technology, offering good contrast and response speed. While its viewing angles (70/70/45/55) are within industrial standards, this mature model is known for very stable color consistency.
Is this a dual-lamp or single-lamp screen? Do you have the matching inverter board?
This model is equipped with a dual-lamp (2-CCFL) backlight system. We can provide either the original or a compatible inverter board to ensure uniform backlight brightness.
Since this model has been in production for a while, how do you guarantee the quality of your stock?
We conduct strict power-on aging tests on every unit before shipment, checking for dead pixels, bright lines, or backlight aging (reddish tint). We can provide live testing videos of the specific serial number before shipping.
