The NEC NL6448BC33-46 is a 10.4-inch TFT color LCD module built on an a-Si TFT-LCD panel with CCFL edge-lit backlight, delivering 640×480 VGA resolution across a 4:3 display. Engineered for industrial environments, it combines 350 cd/m² brightness, 300:1 contrast ratio, and 262,144-color (6-bit) output with a 3H hard-coated surface and landscape orientation. The module accepts parallel RGB CMOS signaling via HRS 31-pin connector and operates across 0–65 °C with standard face-mount installation.
