DMF-50036NFU-FW Specification

DMF-50036NFU-FW | High-Clarity 240x64 Monochrome Graphic LCD

The DMF-50036NFU-FW is an industrial-grade monochrome graphic LCD module engineered for applications where clarity, reliability, and operational longevity are non-negotiable. This display provides a precise and unambiguous human-machine interface (HMI) solution, built to perform consistently across a wide range of demanding environments. It is an ideal choice for new designs and as a form-fit-function replacement for legacy displays in long-life industrial equipment.

An Engineer's Look at the DMF-50036NFU-FW's Core Technology

The performance of the DMF-50036NFU-FW is rooted in two key design choices: its display fluid technology and its illumination system. This is not just a standard display; it's a component built with specific industrial challenges in mind.

  • Film-compensated Super-twisted Nematic (FSTN) Display: Unlike older STN technologies, FSTN incorporates a retardation film between the STN glass and the front polarizer. This engineering step corrects color dispersion, resulting in a highly contrasted, black-and-white display. For an operator, this translates to superior character and graphic legibility, reducing the potential for misinterpretation in critical monitoring tasks.
  • High-Efficiency LED Backlight: The module integrates a modern white LED backlight, a significant upgrade over legacy CCFL systems. This provides not only brighter, more uniform illumination but also substantial benefits in terms of system design. The LED backlight offers a dramatically longer operational lifespan (MTBF), lower power consumption, and operates on a simple DC voltage, simplifying the power supply and driver circuitry. This enhances the overall reliability of the end product, a key factor in industrial applications. For more details on this, explore our deep dive into the energy efficiency of LED backlights.

Engineered for Clarity and Reliability in Demanding Applications

The robust feature set of the DMF-50036NFU-FW makes it a workhorse component across several key industrial sectors. Its value is demonstrated not just in its specifications, but in how it solves real-world engineering challenges.

In industrial control panels and PLC interfaces, the wide operating temperature and high-contrast FSTN display ensure that critical process data is readable in fluctuating factory floor conditions, from cold startups to high-temperature processing areas. Its resistance to vibration and shock is essential for reliable operation in heavy machinery.

For test and measurement instruments, both benchtop and portable, the display’s low power draw is a distinct advantage. The transflective properties mean it is readable in bright ambient light without the backlight, conserving battery life in field instruments. The sharp 240x64 resolution is perfect for rendering waveforms, system menus, and measurement values with precision. This type of passive-matrix display technology is a foundational element, preceding more complex active-matrix technologies like a-Si TFT.

In medical diagnostic equipment, the stable, long-life performance and clear, unambiguous output are paramount for user interfaces that guide technicians through complex procedures. The DMF-50036NFU-FW provides the reliability needed for devices with long service life requirements.

Technical FAQ for the DMF-50036NFU-FW

Is this display a direct "drop-in" replacement for older 240x64 modules?

In many cases, yes. The DMF-50036NFU-FW is designed with standard mechanical footprints and utilizes a common controller IC (RA6963 or compatible). However, it is always best engineering practice to verify the pinout, connector type, and command set against your existing design's datasheet. If you have questions about compatibility, please contact our technical team for support.

What is the primary benefit of a 'transflective' display mode?

A transflective display combines the features of both transmissive and reflective displays. In low-light conditions, the LED backlight transmits light through the display for excellent clarity. In bright ambient light (e.g., outdoors or under intense overhead lighting), the display reflects the ambient light back to the viewer. This dual-mode capability makes it exceptionally versatile and ensures readability across all lighting conditions while offering the potential to save significant power by turning off the backlight when not needed.
