The Kyocera KG057QV1CA-G050 is a 5.7-inch monochrome FSTN-LCD module designed for applications where low power consumption, reliable readability, and straightforward monochrome visual output are essential. Featuring a QVGA resolution of 320 × 240 pixels and a pixel density of 70 PPI, it offers sufficient graphical fidelity for text-centric UIs, system diagnostics, or legacy embedded solutions.
Constructed for compact integration, the display provides a generous active area of 115.2(W) × 86.4(H) mm, enclosed within overall dimensions of 144(W) × 104.8(H) × 13.2(D) mm, making it suitable for control panels, industrial interfaces, and space-constrained environments.
The typical luminance of 220 cd/m² enables functional visibility under moderate lighting conditions. However, its contrast ratio of 40:1 and limited viewing angles (Left/Right: 45°, Up: 30°, Down: 40° @ CR≥2) restrict performance to direct, head-on viewing, ideal for use in stationary setups with consistent operator positioning.
Built on FSTN (Film-compensated Super Twisted Nematic) LCD technology, the panel enhances clarity compared to conventional STN displays, delivering improved readability of monochrome content. However, the glare surface (Haze 0%) may reflect light in bright environments, which could affect readability in outdoor or highly lit spaces.
Operating in STN, transmissive mode, the module strikes a balance between energy efficiency and moderate visual quality, making it a reliable display for static or infrequently updated content. The display's slow response time of ~500 ms confirms its design focus on low-motion applications such as process indicators, configuration screens, and menu-based systems.
Illuminated by a single CCFL backlight rated for up to 58,000 hours, the unit ensures long operational life. Furthermore, its support for 3.3V or 5.0V supply input offers compatibility across a range of embedded system voltages, improving system design flexibility.
