LQ084V1DG42 Sharp 8.4 inch 640*480 LCD display panel
The Sharp LQ084V1DG42 is an 8.4-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 170.88 mm × 128.16 mm, with overall outline dimensions of roughly 199.0 × 148.0 × 12.0 mm. The panel supports 18-bit parallel RGB 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 3.5W (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 500 Vrms to 600 Vrms. Operating temperature range is -10°C to +65°C, with a storage range of -30°C to +80°C. The module features a 31-pin connector (typically DF9B-31P-1V or compatible) for signal interface.
LQ084V1DG42 Sharp LCD display panel Key Highlights:
Excellent image clarity – The 8.4-inch VGA (640×480) resolution delivers crisp, detailed visuals with high contrast ratio (typically 250:1 ) and brightness of approximately 350 cd/m², ideal for medical imaging, industrial HMI, and test equipment.
Wide operating temperature range – Rated for -10°C to +65°C, ensuring reliable performance in demanding environments such as factory automation, outdoor terminals, and automotive diagnostic tools.
Dual CCFL backlight – Provides superior brightness uniformity and long backlight lifetime (typically 50,000+ hours to half-brightness) , suitable for 24/7 continuous operation applications.
Robust industrial-grade construction – With a slim 11.0 mm thickness, this panel offers mechanical durability and long-term reliability for mission-critical systems.
Legacy-compatible interface – The dual-voltage logic (3.3V/5.0V selectable) and standard 18-bit parallel RGB interface allow easy drop-in replacement or upgrades for existing VGA display systems without major redesign.
Long product life cycle support – Sharp's commitment to extended production minimizes obsolescence risks for industrial, medical, and military applications.
