The Kyocera KCG057QV1DB-G77 is a 5.7-inch CSTN-LCD module offering a QVGA resolution of 320×240 pixels with a 70 PPI pixel density, suitable for applications where moderate display clarity is acceptable. Designed primarily for industrial, control panel, and low-motion graphical interfaces, it delivers reliable performance in environments that do not demand rapid image transitions or high contrast visuals.
This display panel provides 380 cd/m² luminance, ensuring good screen visibility in typical indoor lighting conditions. While the contrast ratio of 60:1 (typical) is modest, it is sufficient for general-purpose use cases where ultra-high contrast isn't critical. The viewing angles of 55° horizontally and 75° vertically offer decent readability when viewed off-axis, though limited compared to modern IPS or TFT panels.
Operating in CSTN, Normally Black, Transmissive mode, this display achieves basic color output and improved perceived contrast in black-state conditions. It uses a single CCFL backlight, delivering a lifetime of approximately 75,000 hours, although it does not include a backlight driver, which needs to be sourced separately for proper operation.
The response time of 450 ms (typical) is relatively slow, resulting in visible motion blur or ghosting during fast image transitions. As such, this module is better suited to static or slowly-updating display applications rather than dynamic video or real-time graphical interfaces.
