The NEC NL6448AC30-12 is a compact 9.4-inch a-Si TFT-LCD module engineered for industrial and commercial applications where reliable display quality and long service life are essential. It provides a VGA resolution of 640 × 480 pixels with a 4:3 aspect ratio and an active display area of 192 × 144 mm. The overall module dimensions are approximately 241.8 × 178.8 × 10 mm, making it suitable for industrial HMIs, embedded systems, medical devices, notebook repairs, CNC equipment, and process control terminals.
The display uses TN, Normally White, Transmissive TFT technology with RGB vertical stripe arrangement and supports up to 4,096 colors through a 4-bit signal structure. It delivers a typical brightness of 70 cd/m² with a contrast ratio of 150:1, making it suitable for indoor industrial environments and legacy equipment. Viewing angles are approximately 45° left/right and 25° up/down, with an upper viewing direction optimized to reduce image inversion.
The NL6448AC30-12 includes a single edge-lit CCFL backlight located at the bottom side of the panel. The lamp operates at approximately 450V with a typical current of 3.7 mA and is designed for inverter-less integration. Replacement CCFL lamps remain available for maintenance and refurbishment of older systems.
The module uses a 31-pin Parallel RGB CMOS interface with 1-channel 4-bit signal input and operates on a typical 5.0V supply voltage. Total power consumption is approximately 2.7W, making it suitable for long-running industrial applications. It supports a standard 60Hz vertical refresh rate and uses face mounting holes for secure installation.
The display supports an operating temperature range of 0°C to 50°C and storage temperatures from -20°C to 60°C. Community discussions note that this panel is commonly used in vintage NEC laptop systems and industrial replacements, but matching the correct controller board, inverter, and connector pinout is important when integrating it into modern systems.
