The Kyocera KG057QV1CA-G00 is a 5.7-inch monochrome FSTN-LCD module designed for embedded and industrial applications requiring efficient power usage, good readability, and long operational lifespan. Featuring a QVGA resolution of 320 × 240 pixels with a pixel density of 70 PPI, it provides clear and sharp monochrome output in black and white (negative) mode, making it ideal for status displays, control panels, instrumentation, and legacy system upgrades.
With an active display area of 115.18 × 86.38 mm, the display balances clarity and size, while fitting efficiently into compact housings. The panel delivers a luminance of 220 cd/m² and a contrast ratio of 10:1, making it suitable for use in moderately lit indoor environments. The FSTN technology (Film-compensated Super Twisted Nematic) enhances contrast and viewing performance compared to standard STN displays, delivering better readability for text-rich interfaces.
This display supports viewing angles of 45° left/right, 20° up, and 45° down (CR ≥ 2), allowing moderate flexibility in installation orientation. The response time of 210 ms (rise) and 130 ms (fall) supports relatively static or slowly updating content, such as menus, diagnostics, or monitoring data.
The display operates in STN mode with glare surface treatment (Haze 0%), providing sharp visuals, though some reflectivity may be observed in high ambient light. The parallel interface (1 channel, 4-bit) via a 20-pin connector allows straightforward integration into various embedded systems, and the 75Hz frame rate ensures flicker-free image rendering.
Powered by 3.3V or 5.0V, the module offers voltage flexibility for various logic-level systems. The CCFL backlight system provides consistent illumination with a lifetime of up to 58,000 hours, though it requires an external CCFL inverter for operation. The display is robust for industrial environments, supporting operating temperatures from 0°C to 60°C, and storage temperatures from -20°C to 60°C, ensuring reliable performance over time.
