SHARP LQ057Q3DC12

The Sharp LQ057Q3DC12 is a 5.7-inch a-Si TFT-LCD panel widely used in industrial and professional display applications. It features a 320 × 240 pixel (QVGA) resolution with a 4:3 aspect ratio, providing clear and stable image output suitable for control panels, HMI systems, and embedded interfaces. The display operates in TN (Twisted Nematic), normally white, transmissive mode and supports up to 262K colors (6-bit) for consistent color performance.

In terms of optical performance, the panel offers a typical brightness of around 500 cd/m² and a contrast ratio of approximately 350:1, ensuring good visibility even in bright environments. It provides viewing angles of about 65/65/65/40 (left/right/up/down) and fast response times, making it suitable for real-time display applications.

The module uses a parallel RGB interface (33-pin, 6-bit) and operates at a typical voltage of 3.3V, allowing easy integration with embedded systems and industrial controllers. It is equipped with a CCFL backlight with a long lifespan of up to 50,000 hours, ensuring reliable long-term operation.

Mechanically, the display has compact dimensions of approximately 144 × 104.6 × 12–13 mm, with an active area of about 115.2 × 86.4 mm, making it suitable for space-constrained designs. It also supports a wide operating temperature range of –30°C to +80°C, enabling use in harsh environments.
