The Kyocera KCS057QV1BR-G21 is a 5.7-inch CSTN (Color Super-Twisted Nematic) LCD module offering a QVGA resolution of 320 × 240 pixels and a pixel density of 70 PPI. Engineered for embedded systems, control interfaces, and industrial devices, it provides a balance of compact size and moderate visual clarity for both textual and graphical data.
The display features a normally black, transmissive mode, which improves contrast under ambient lighting conditions. Although STN-based displays are typically monochrome, this model supports color display, expanding its usability for applications requiring more detailed UI elements or status visuals.
Its active display area measures 115.2 mm (W) × 86.4 mm (H), offering a well-proportioned layout for user interaction or monitoring interfaces. The parallel 1-channel 8-bit interface provides wide compatibility with common microcontrollers, FPGAs, and industrial controllers.
A single CCFL backlight ensures reliable brightness, although it necessitates an external inverter or driver circuit. The backlight system is designed for long-term use, typically suitable for industrial environments, though specific brightness and contrast values are not documented.
Thanks to its wide operational and storage temperature support, the KCS057QV1BR-G21 is appropriate for harsh or variable environments, maintaining display integrity in applications such as factory automation, diagnostic systems, and rugged handheld devices.
