SHARP LQ121S1DG41

The Sharp LQ121S1DG41 is a 12.1-inch a-Si TFT-LCD module designed for industrial and professional display applications. It features a resolution of 800 × 600 pixels (SVGA) with a 4:3 aspect ratio, delivering clear and stable image quality for control panels, HMI systems, and legacy equipment. The panel operates in TN (Twisted Nematic), normally white, transmissive mode and supports up to 262K colors, ensuring consistent display performance.

In terms of optical performance, the display offers a typical brightness of around 370 cd/m² and a contrast ratio ranging from 150:1 to 450:1, providing good readability in industrial environments. It also features viewing angles of approximately 70/70/50/60 (left/right/up/down) and includes an anti-glare surface, which reduces reflections and enhances visibility.

The module uses a parallel RGB interface (1-channel, 6-bit, ~41-pin connector) and operates at typical voltages of 3.3V–5V, enabling easy integration with embedded systems and controllers. It is equipped with a dual CCFL backlight system (edge-lit) with a lifespan of up to 50,000 hours, and the lamps are replaceable, extending the product’s service life.

Mechanically, the display has dimensions of approximately 276 × 209 × 11 mm, with an active display area of about 246 × 184.5 mm, and weighs around 660 g. It supports a wide operating temperature range of –30°C to +70°C (storage up to –30°C to +70°C), making it suitable for demanding industrial environments.
