SAMSUNG LTM170EX-L31 LCD Display

Samsung LTM170EX-L31 | High-Contrast 17.0" SXGA Industrial LCD Display

The Samsung LTM170EX-L31 is a 17.0-inch a-Si TFT-LCD panel engineered for applications where visual precision, reliability, and long-term stability are non-negotiable. While many displays focus on brightness, the LTM170EX-L31 distinguishes itself with exceptional image fidelity, making it a premier choice for legacy system upgrades and specialized equipment in controlled industrial and medical environments.

Engineered for Visual Performance and Durability

The LTM170EX-L31 is not just another screen; it's a component designed for critical tasks. Its value is rooted in a combination of core display technologies that ensure what you see is accurate and clear from any angle.

• Exceptional Image Clarity: A native SXGA (1280x1024) resolution on a 17-inch screen provides high pixel density for sharp text and detailed graphics, essential for complex user interfaces and data analysis.
• Superior Contrast and Color: With a typical Contrast Ratio of 1000:1 and 72% NTSC color gamut, this panel delivers deep blacks, vibrant colors, and subtle grayscale differentiation crucial for medical imaging and industrial monitoring.
• Consistent Off-Axis Viewing: Symmetrical viewing angles of 80/80/80/80 ensure that colors and contrast remain true, even when the display is viewed from significant off-axis positions—a vital feature for multi-person workstations or large control consoles.
• Proven System Compatibility: The integration of a standard LVDS Interface and a CCFL backlight system makes the LTM170EX-L31 an ideal drop-in replacement for aging industrial displays, minimizing the need for costly redesigns of driver boards and power systems.

Technical Deep Dive: The Engineering Behind the Image

Two core attributes define the LTM170EX-L31's engineering philosophy: uncompromising visual fidelity and robust, predictable performance. The underlying technology directly supports the demanding requirements of its target applications.

First, the panel's high-contrast amorphous silicon (a-Si TFT) cell structure is the foundation of its superior image quality. Unlike standard consumer-grade displays, this panel is optimized to minimize light leakage in the "off" state, resulting in a significantly higher static contrast ratio. For a design engineer in the medical field, this translates to the ability to discern subtle gradations in grayscale images like X-rays or CT scans. In an industrial control setting, it means alarms and status indicators are rendered with unambiguous clarity against dark backgrounds, reducing operator error.

Second is the deliberate use of a Cold Cathode Fluorescent Lamp (CCFL) backlight. In an era dominated by LEDs, the CCFL system in the LTM170EX-L31 offers a distinct advantage for long-life cycle systems. It provides a stable and well-characterized spectral output, ensuring consistent color performance over years of operation. Furthermore, for engineers maintaining or retrofitting existing systems, its standard inverter-based power requirement simplifies integration, avoiding the complex driver redesigns often needed when migrating to LED backlights. This focus on stability and backward compatibility is a hallmark of truly industrial-grade components.

Application-Specific Value Proposition

The LTM170EX-L31 excels where generic displays fall short. Its features provide tangible benefits in several key sectors:

• Medical Diagnostic Stations: The high contrast and SXGA resolution are essential for accurate analysis of diagnostic imagery, where every detail matters. The stable color performance ensures that what the technician sees today will be identical to what they see years from now.
• Industrial Process Control (HMI): In a factory setting, wide viewing angles allow multiple operators to monitor a single screen without color shift or loss of information. The fast 5ms response time ensures that rapidly changing process data is displayed without motion blur.
• Test & Measurement Equipment: For oscilloscopes, spectrum analyzers, and other precision instruments, the display is the primary user interface. The LTM170EX-L31’s sharpness and color accuracy ensure that waveforms and measurement data are interpreted correctly. It is a core component in our range of industrial LCD displays.

Frequently Asked Questions for Engineers

Is the CCFL backlight a disadvantage compared to modern LEDs?
Not for its intended application. For new, cutting-edge designs, LEDs offer power efficiency and form factor benefits. However, for replacing displays in existing, validated systems, a CCFL backlight is often superior. It guarantees electrical compatibility with legacy inverters and provides a highly stable, proven light source, avoiding the risk and cost of re-engineering and re-validating the system's electronics.

How does the LTM170EX-L31 compare to a modern IPS panel?
This panel's performance is highly competitive with many modern IPS panels in its class, particularly in contrast and response time. The LTM170EX-L31 was designed using Samsung's advanced PVA (Patterned Vertical Alignment) technology, which was a precursor to modern high-contrast display tech and is known for delivering deep blacks and wide viewing angles comparable to IPS (In-Plane Switching). Its 5ms response time is often faster than many industrial IPS displays, making it an excellent choice for dynamic content.
