The Optrex DMF50840NF-FW is a 5.7-inch FSTN-LCD module designed to provide a durable and compact display solution for monochrome applications in industrial, embedded, and control environments. It features a QVGA resolution of 320×240 pixels with a 70 PPI pixel density, delivering clear and precise monochrome visuals across a 115.2(W) × 86.4(H) mm active area.
Encased in a 167.1(W) × 109(H) × 11(D) mm housing, the module is built using STN (Super Twisted Nematic) technology, configured in a black/white (negative), transmissive mode. It provides a typical contrast ratio of 15:1 and a brightness of 50 cd/m², making it suitable for indoor applications under stable lighting conditions.
The display supports viewing angles of 40°/50°/30°/40° (L/R/U/D, CR≥2) and has a response time of 420 ms (rise) / 210 ms (fall), which is typical for FSTN displays focusing on static or slowly updating content.
For connectivity, the module uses a Parallel Data (1ch, 4-bit) interface with a 14-pin FPC connector. It operates at a 75Hz refresh rate, ensuring flicker-free image rendering.
Backlighting is handled by a single CCFL unit, rated for a lifespan of 25,000 hours, although the backlight driver is not integrated. The module operates within a temperature range of 0°C to 50°C, and supports storage conditions from -20°C to 60°C, making it a practical choice for embedded systems in stable environments where low power usage and reliability are key.
