LQ121S1DG41 Sharp 12.1 inch 800*600 CCFL display modules
The Sharp LQ121S1DG41 is a 12.1-inch active matrix TFT-LCD display module with a resolution of 800 × 600 pixels (SVGA). It features a transmissive display mode with normally white operation. The active area measures approximately 246(W)×184.5(H) mm, with overall outline dimensions of roughly 276(W)×209(H)×11(D) mm. The panel supports 18-bit parallel RGB interface (typically 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 3.0W to 4.0W (excluding backlight). The module uses dual CCFL (Cold Cathode Fluorescent Lamp) backlighting, requiring an external inverter with typical lamp current of 6.0 mA and lamp voltage of approximately 600 Vrms. Operating temperature range is 10°C to +65°C, with a storage range of -30°C to +70°C. The module features a 41-pin connector (typically DF9B-31P-1V or compatible) for signal interface.
LQ121S1DG41 Sharp CCFL display modules Key Highlights:
High brightness and uniform illumination – The dual CCFL backlight delivers excellent luminance (typically 370 cd/m²) and superior screen uniformity, ideal for industrial control panels, medical monitors, and arcade/gaming machines.
Large format with sharp SVGA resolution – The 12.1-inch diagonal and 800×600 pixel density provides ample display area and clear text/image reproduction for operator interfaces and instrumentation.
Proven reliability – Sharp's robust TFT technology offers long operational lifetime (CCFL backlight typically rated for 50,000+ hours to half-brightness) and stable performance in extended-use environments.
Flexible compatibility – The dual-voltage logic (3.3V/5.0V selectable) and standard 18-bit RGB interface allow easy integration with a wide range of legacy and new controller boards.
Industrial-grade durability – Designed for continuous operation in demanding applications such as factory automation, kiosks, and test equipment, with mechanical robustness and long-term availability from Sharp.

FAQ:
Is this screen CCFL or LED backlight? How much longer is the expected life of the backlight tubes?
The LQ121S1DG41 uses dual CCFL backlights. For brand-new original units, the backlight life is typically 50,000 hours. For older stock, we re-test the brightness to ensure there is no aging or reddish tint in the backlight.
This model has been discontinued for a long time. Is your current stock brand-new original, or is it pulled/used?
We still have a limited stock of brand-new original units. If you have a limited budget, we can also provide Grade A pulled/used units, all of which undergo strict display testing and cleaning.
Shipping large glass screens by air is risky. What happens if the screen arrives broken?
We use professional EPE foam brackets and reinforced wooden frames (for bulk) for protection. We also purchase shipping insurance for every batch. If damage occurs, please take photos and contact us within 24 hours of receipt, and we will handle the full compensation or reshipment.
