Introduction and Core Highlights
The Samsung LTM170E4-L01 is an a-Si TFT-LCD active matrix display module engineered for consistent, reliable performance in industrial and commercial applications. Its value is rooted in a stable design that combines a standard 1280×1024 (SXGA) resolution with a proven 2-channel LVDS interface, providing a dependable component for long-lifecycle systems. This module is well-suited for applications where clear data representation and predictable integration are paramount. For system designers, this means a reduced integration risk and a stable platform for HMI or information display development.
- Core Specifications: 17.0-inch Diagonal | 1280×1024 SXGA Resolution | 250 cd/m² Brightness (Typ.)
- Key Engineering Advantages: Standardized LVDS interface simplifies driver board design and reduces EMI. The “Normally Black” PVA mode ensures a high-contrast, deep black state.
- Reduces Integration Headaches: The panel’s 5:4 aspect ratio and conventional LVDS signaling make it a straightforward replacement for many aging industrial displays.

Technical Analysis for System Integration
The engineering value of the LTM170E4-L01 is found in its datasheet-verified specifications, which guarantee predictable behavior for system designers. The module’s 2-channel, 8-bit LVDS interface is a primary asset. Think of this interface as a dedicated, shielded highway for pixel data. It allows for high-speed transmission of the panel’s 1280×1024 resolution with lower electromagnetic interference (EMI) compared to older TTL interfaces. This simplifies PCB layout and helps systems meet global certification standards. For engineers, this translates to a more robust and compliant final product.
The optical performance is defined by its PVA (Patterned Vertical Alignment) display mode and “Normally Black” characteristic. This technology provides a typical contrast ratio of 350:1 and wide viewing angles of 80 degrees in all directions (L/R/U/D). The “Normally Black” feature means that in an off-pixel state, the liquid crystals block light, resulting in deeper blacks and preventing a washed-out look. This is critical for applications where data clarity and text legibility are essential, ensuring that operators can accurately read information from various positions without significant color or contrast shift. Efficient thermal management is also key, as the total power consumption is specified at 15.6 watts typically (panel and backlight).
Optimized Application Scenarios
The specific feature set of the LTM170E4-L01 makes it an effective component for several established applications:
- Industrial HMI Panels: The SXGA resolution and 5:4 aspect ratio are a perfect match for many legacy SCADA and control software interfaces, ensuring direct compatibility without UI distortion.
- Medical Workstation Displays (Non-Diagnostic): Ideal for patient monitoring systems and equipment control interfaces where a standard resolution and reliable performance are required. The wide viewing angles allow multiple personnel to view the screen clearly.
- Point-of-Sale (POS) Terminals: Its robust construction, featuring an anti-glare surface and hard coating (3H), withstands the demands of a commercial environment.
- Instrumentation and Test Equipment: Provides a clear, detailed readout for complex data, graphs, and measurements, where precision is more important than video playback speed.
This module’s specifications make it a best-fit choice for systems that demand a proven, no-frills 17-inch SXGA display with a standard LVDS input.

Engineer’s FAQ
- What are the LVDS pinout and signaling requirements for the LTM170E4-L01?
- The module uses a standard 30-pin connector (FI-X30S-HF or equivalent) for its 2-channel, 8-bit LVDS interface. The datasheet provides a detailed pin assignment, including differential data pairs, clock signals, and power lines. Adhering to proper impedance control on the PCB is crucial for signal integrity, a topic further explored in our guide to mastering signal integrity.
- How should I manage the heat from the CCFL backlight?
- The CCFL backlight contributes significantly to the module’s 15.6W typical total power consumption. System enclosures must provide adequate ventilation (passive or active) to keep the ambient temperature around the panel below its 50°C maximum operating limit. Ensure there is sufficient clearance around the top and bottom edges where the CCFL lamps are located for heat to dissipate.
- Is the LTM170E4-L01 a good choice for a new industrial control panel design?
- Yes, if the design prioritizes stability, a 5:4 aspect ratio, and does not require cutting-edge features like ultra-high brightness or touch integration. Its proven a-Si technology and standard SXGA resolution make it a low-risk choice for industrial HMIs where software is often validated for this specific format. For a deeper look at modern HMI requirements, see our article on smart factory HMI specifications.
- Does this panel comply with RoHS regulations?
- Yes, the official datasheet for the LTM170E4-L01 confirms that the module is RoHS compliant, meeting the required environmental standards for hazardous substances.
