Sharp LQ170M1LW2A: A High-Resolution Display for Industrial and Medical Systems
Sharp LQ170M1LW2A 17.0-inch WUXGA TFT-LCD Module
High-Resolution Imaging for Demanding Industrial Applications
The Sharp LQ170M1LW2A is a 17.0-inch amorphous silicon TFT-LCD module engineered for applications requiring superior image detail and clarity. Its key distinction is the high-density WUXGA resolution (1920 x 1200 pixels), which delivers exceptionally sharp and precise image rendering. This makes it a strong candidate for systems where visual accuracy is critical for operational success.
- Core Specifications: 17.0-inch Diagonal | 1920 x 1200 (WUXGA) | LVDS Interface
- Key Advantages: Provides high pixel density for detailed analysis. Features a matte, anti-reflective surface for usability in varied lighting.
- Primary Use Case: Ideal for high-resolution industrial HMIs, medical imaging systems, and test equipment where clear, detailed visuals are essential for accurate data interpretation.

Technical Analysis for System Integration
The defining feature of the LQ170M1LW2A is its WUXGA (1920 x 1200) resolution. This 16:10 aspect ratio provides more vertical screen real estate compared to standard Full HD (1920×1080) displays, which is beneficial for displaying extensive datasets, complex schematics, or detailed diagnostic imagery without excessive scrolling. The pixel pitch of 0.1905 mm results in a high-density display that renders fine lines and text with exceptional sharpness, a critical requirement for accurate analysis in technical applications.
The module’s optical performance is characterized by a typical brightness of 230 cd/m² and a contrast ratio of 500:1. This level of performance is suitable for controlled indoor environments typical of control rooms, laboratories, and medical facilities. The viewing angles are specified at 70°/70° (Horizontal) and 50°/60° (Vertical), which is characteristic of TN panel technology. This performance ensures that an operator directly in front of the display will see a clear image, which is a key consideration for single-user workstations. The importance of the contrast ratio can be compared to the clarity of a radio signal; a higher ratio means a clearer distinction between the signal (the intended image) and the noise (lack of differentiation), ensuring that subtle variations in grayscale are visible.
Optimized Application Scenarios
The specific characteristics of the LQ170M1LW2A align it with several professional use cases:
- Medical Imaging Displays: The high WUXGA resolution is critical for the detailed review of X-rays, CT scans, and other medical diagnostics where precision is essential.
- Industrial Control Panels: In factory automation, the 16:10 aspect ratio and sharp text rendering allow for the clear display of complex SCADA interfaces and process diagrams.
- Scientific and Test Equipment: The high pixel density ensures that intricate waveforms, charts, and measurement data from specialized equipment are rendered with clarity.
- Broadcasting and Video Production: Suitable for use as a monitoring display in editing suites where accurate representation of high-resolution content is necessary before final output.
This module’s high resolution and standard LVDS interface make it a strong candidate for upgrading or maintaining systems that require precise visual fidelity.

Engineer’s FAQ
What type of graphics controller is required for the LQ170M1LW2A?
An integrator will need a display controller board that can output a dual-channel, 6-bit LVDS signal capable of driving a 1920×1200 resolution at 60Hz. The controller must also supply the specified 3.3V to the panel.
How is the CCFL backlight powered and controlled?
The LQ170M1LW2A module includes an inverter for the single CCFL tube. The inverter requires its own power input, separate from the panel’s 3.3V logic supply, and will have pins for enable and brightness control, typically via a PWM signal or analog voltage.
What are the main considerations for mechanical mounting?
The outline dimensions are 382.2 x 266.8 x 7.0 mm. Engineers should design a bezel or enclosure that supports the panel by its mounting tabs without putting stress on the glass or the PCB, especially near the delicate LVDS and backlight connectors.
Is this display suitable for outdoor use?
No. The specified operating temperature range of 0 to 50°C and the typical brightness of 230 cd/m² indicate that the LQ170M1LW2A is designed for indoor, controlled environments and is not suitable for direct sunlight or extreme temperature applications.
Enabling High-Fidelity System Design
The LQ170M1LW2A delivers the high-resolution performance necessary for specialized industrial and medical systems. Its WUXGA format provides a detailed canvas for critical data visualization, while its standard LVDS interface facilitates integration into a variety of system architectures. This combination of features supports the design of precise and reliable instrumentation where image clarity is a non-negotiable requirement. For engineers developing next-generation machine vision or diagnostic tools, this display provides the foundational visual performance needed.
