Application Scenarios & Value
System-Level Benefits in Industrial and Medical HMIs
For designers of industrial control panels, point-of-sale (POS) terminals, and medical diagnostic equipment, the M170EG01 V9 offers a compelling combination of performance and physical attributes. Its high brightness of 420 cd/m² and a typical contrast ratio of 500:1 ensure excellent readability in varied indoor lighting environments, a critical factor for reducing operator error in factory settings or ensuring diagnostic clarity in medical labs. The use of a mature CCFL backlight system provides a known performance and lifetime curve, simplifying maintenance schedules and total cost of ownership calculations. The panel's standard 2-channel LVDS interface facilitates straightforward integration with a wide range of industrial motherboards and single-board computers, minimizing the need for complex interface conversion hardware. This focus on proven technology makes it an excellent choice for applications prioritizing stability and regulatory validation over cutting-edge display trends.
For applications demanding a different form factor or higher resolution, related models such as the G156XW01 V0 offer alternative display solutions within a broader portfolio.
Key Parameter Overview
Decoding the Specs for Application-Specific Performance
The specifications of the AUO M170EG01 V9 are tailored for embedded applications where precise image reproduction and mechanical durability are key design criteria. The 1280x1024 SXGA resolution on a 17.0-inch diagonal screen provides a pixel density of 96 PPI, which is ideal for displaying complex graphical user interfaces (GUIs) and detailed process information without requiring scaling. The 8ms typical response time is sufficient for the dynamic content found in most industrial monitoring and control applications, ensuring fluid animations and clear video feeds. A notable feature is the 72% NTSC color saturation, which allows for vibrant and accurate color reproduction, essential for applications like medical imaging or brand-sensitive POS systems where color fidelity cannot be compromised.

Technical Deep Dive
A Closer Look at the Display's Optical and Mechanical Design
The M170EG01 V9 is built using a-Si (Amorphous Silicon) TFT technology, a proven and cost-effective manufacturing process known for its stability and reliability in industrial-grade displays. The panel's surface features a glare treatment (Haze 0%) and a 2H hard coating, which enhances perceived contrast and protects the screen from scratches in high-traffic environments like public kiosks or factory floors. Mechanically, the module's outline of 358.5(W) × 296.5(H) × 17.5(D) mm and weight of 1.90Kgs provide a sturdy, robust structure. This physical resilience is critical; think of it as the display's chassis. Just as a vehicle's frame determines its durability, the mechanical design of this module ensures it can withstand the incidental bumps and vibrations common in its intended operating environments without compromising the sensitive internal components.
Frequently Asked Questions (FAQ)
What is the primary benefit of the M170EG01 V9's 5:4 aspect ratio?
The 5:4 aspect ratio is highly advantageous for legacy industrial software and systems originally designed for this squarer format. It allows for direct, one-to-one replacement of older CRT or LCD monitors without requiring software redesign or dealing with image stretching and distortion that occurs when fitting a 5:4 interface onto a widescreen display.
How does the 420-nit brightness impact system design?
A brightness of 420 cd/m² (nits) provides excellent readability for indoor applications. For a system designer, this means the display can be integrated into environments like factory floors, retail stores, or medical facilities without needing an additional high-brightness enhancement or a protective hood to shield it from ambient light, simplifying the mechanical enclosure design.
Is an external inverter required for the backlight?
Yes, the datasheet specifies that this module utilizes a 4-piece CCFL backlight system and does not include an integrated inverter card. System integrators must source and incorporate a compatible CCFL inverter to power the backlight. This modular approach allows designers to select an inverter that best fits their system's specific power supply and control requirements.
