KYOCERA KG057QV1CA-G020

The Kyocera KG057QV1CA-G020 is a high-quality 5.7-inch STN-LCD module developed for industrial and professional applications that require reliable monochrome display performance. It provides a QVGA resolution of 320 × 240 pixels with a 4:3 aspect ratio and a pixel density of approximately 70 PPI, making it suitable for industrial machinery, medical instruments, process control equipment, and embedded systems. The active display area measures 115.18 × 86.38 mm within an overall module size of 144 × 104.8 × 12.7 mm.

The display uses STN Blue Mode Negative Transmissive technology and supports monochrome output with strong visibility for industrial text, symbols, and graphical information. It offers a typical brightness of 260 cd/m² with a contrast ratio of 4:1 and viewing angles of 45/45/20/40 degrees. Its glare surface and landscape orientation make it suitable for fixed front-facing industrial installations.

The KG057QV1CA-G020 includes a single edge-lit CCFL backlight with a rated life of approximately 58,000 hours, providing long-term illumination reliability. It uses a 20-pin parallel data interface with 4-bit or 6-bit signal support and can operate on either 3.3V or 5.0V input voltage, making it easier to integrate into both older and newer industrial control systems.

The module supports an operating temperature range of 0°C to 60°C and storage temperatures from -20°C to 60°C. It also includes rear mounting holes for secure installation and weighs approximately 175 grams, making it suitable for rugged industrial environments and replacement display applications. Reddit users often note that for older industrial LCD replacements, exact connector layout, signal interface, and mounting compatibility are critical to ensure proper operation.
