The NEC NL6448AC33-29 is a 10.4-inch TFT active matrix color LCD panel engineered for industrial control and process monitoring applications. Built on amorphous silicon technology, this display delivers 640 × 480 resolution with 262,144 colors and 150:1 contrast ratio. The integrated edge-light backlight system features two long-life, replaceable lamps paired with an onboard inverter, ensuring extended operational life in demanding environments. Ultra-wide viewing angles (80°/80°/80°/80° horizontal/vertical, CR≥10) enable reliable information presentation across diverse viewing positions. The panel accepts standard 6-bit digital RGB input via 31-pin connector with Data Enable function and supports reversible scan direction for flexible integration. Clear antireflection surface treatment minimizes glare in bright operational spaces.
