Overview

NL6448AC20-02 is a legacy industrial-grade a-Si TFT-LCD module manufactured by NLT Technologies (formerly NEC LCD). This 6.5-inch panel delivers standard VGA resolution 640(RGB)×480 with classic 4:3 aspect ratio. Adopting transmissive normally black TFT technology and dual CCFL edge backlight, it features a 31-pin CMOS analog RGB interface, widely deployed as original replacement display for vintage factory automation equipment, CNC controllers, testing instruments and medical auxiliary terminals.

This LCM is highly recognized for stable mechanical mounting layout, reliable long-term static display performance and strong compatibility with legacy industrial control systems. All specifications are sourced from official NLT datasheet to guarantee engineering accuracy for equipment maintenance and screen retrofit projects.

Frequently Asked Questions (FAQ)

Q1: Is NL6448AC20-02 genuine original NLT panel?
A1: Yes. NL6448AC20-02 is an official industrial TFT-LCD module manufactured by NLT Technologies (NEC LCD). We supply Grade A tested modules complying with official datasheet specifications.
Q2: What is the difference between NL6448AC20-02, NL6448AC20-06 and NL6448AC20-08?
A2: NL6448AC20-02: CCFL backlight + Analog RGB interface;
NL6448AC20-06: CCFL backlight with optimized circuit;
NL6448AC20-08: Updated interface variant. Mechanical outline is similar, but backlight and pin definitions differ. Direct swap without verification is not recommended.
Q3: Does this panel need a separate inverter board?
A3: Yes. It uses dual CCFL backlight without built-in inverter. A matched CCFL inverter board is mandatory to power the backlight. It cannot directly connect LED backlight without hardware modification.
Q4: Can I use LVDS or eDP driver boards for this screen?
A4: No. It adopts 31-pin CMOS analog RGB signal interface. LVDS/eDP controller boards cannot drive this panel directly; a dedicated RGB driver board is required.
Q5: Does this module support touch function?
A5: The bare LCD module has no built-in touch. Resistive touch overlay can be bonded externally if touch operation is required.
Q6: Is this panel suitable for 7×24 hours continuous industrial operation?
A6: Designed for indoor industrial continuous usage within 0°C ~ +50°C. For non-stop 7×24h operation, regular inspection of CCFL backlight aging is suggested.
Q7: Can it be used outdoors?
A7: Not recommended. The standard operating temperature range is limited to indoor environments. It lacks wide-temperature and high-brightness design for outdoor exposure.
