A056DN01 V6: Compact 5.6-Inch TFT-LCD for Specialized Visual Interface Applications
The AUO A056DN01 V6 is a 5.6-inch a-Si TFT-LCD module engineered for applications demanding a compact, reliable display with consistent visual performance. Delivering a resolution of 320x234 within a 126.5 x 100 mm frame, it provides a focused solution for systems where space is at a premium but clear visual feedback is essential. With its balanced brightness and proven WLED backlight technology, this display is optimized for long-term integration into specialized equipment. For systems requiring a higher resolution or different interface, the G057VN01 V2 offers a VGA resolution in a similar form factor.
Key Parameter Overview
Decoding the Specs for System Integration
The specifications of the AUO A056DN01 V6 are tailored for straightforward integration into a variety of electronic systems. The combination of its compact physical dimensions, standard analog RGB interface, and multi-voltage power supply requirements define its suitability for targeted applications. A key parameter is its WLED backlight system, which provides a typical brightness of 300 cd/m², a crucial factor for ensuring readability in controlled lighting environments often found in industrial or indoor settings. This brightness level, when paired with the 300:1 contrast ratio, ensures that graphical elements and data are presented with clarity.
Understanding the power supply requirements is also critical for system architects. The display necessitates multiple voltage lines (3.3V, 5.25V, 15V, and -10V), which is characteristic of this display technology generation. This is akin to an engine requiring different fluids for lubrication, cooling, and fuel; each voltage plays a distinct role in powering the logic, analog circuits, and gate drivers that control the liquid crystal pixels. Proper power sequencing and regulation are essential for stable and reliable operation.

Application Scenarios & Value
System-Level Benefits in Embedded Systems and Portable Devices
The AUO A056DN01 V6 is best suited for embedded systems where a compact, cost-effective display is a primary design driver. Its 5.6-inch form factor makes it an excellent candidate for integration into portable media players, digital photo frames, and specialized test equipment where a full HD display would be unnecessary and costly. The key value proposition lies in its simplicity and reliability for displaying essential information without the complexity of modern digital interfaces like LVDS or eDP.
Consider the engineering challenge of designing a portable diagnostic tool for field technicians. The device needs a screen large enough to show measurement data and simple waveforms but must remain compact and power-efficient. The A056DN01 V6's 320x234 resolution is perfectly adequate for this task, presenting clear numerical readouts and status icons. Its analog RGB interface can be driven by a wide range of microcontrollers and legacy graphics processors, simplifying the electronic design and potentially reducing the bill of materials (BOM). The specified operating temperature range of -10 to 60°C ensures it can function reliably in environments from a cool server room to a warm factory floor. For applications requiring a wider temperature range and higher brightness, a model like the AA057QD01 may be a more suitable choice.
Frequently Asked Questions (FAQ)
What is the primary benefit of the A056DN01 V6's analog RGB interface?
The primary benefit is its compatibility with a wide array of simpler, lower-cost graphics controllers and processors. This can lead to a more streamlined and cost-effective system design, particularly for legacy system upgrades or applications that do not require high-speed digital video data transfer.
How does the 300 cd/m² brightness level affect potential applications?
This brightness level is well-suited for indoor or controlled-lighting environments. It provides clear visibility for applications like portable media players, door-phone video systems, or industrial control panels that are not exposed to direct sunlight. It represents a balance between visibility and power consumption for the WLED backlight.
What considerations are necessary for the multi-voltage power supply of this module?
Design engineers must ensure the system's power delivery network can provide four distinct voltages: 3.3V (VCC), 5.25V (AVDD), 15V (VGH), and -10V (VGL). A properly designed power management IC (PMIC) or discrete DC-DC converters are required to generate these rails with low noise and in the correct sequence to prevent damage to the display driver ICs.
Industry Insights & Strategic Advantage
Leveraging Proven Technology for System Reliability and Longevity
In an industry often focused on the highest resolutions and newest interface standards, the AUO A056DN01 V6 offers a strategic advantage rooted in mature, proven technology. The use of a standard analog RGB interface and an a-Si (Amorphous Silicon) TFT panel represents a technology platform with well-understood characteristics and integration requirements. This minimizes design risks and shortens the development cycle for engineers creating products in stable, long-lifecycle markets such as industrial monitoring, security systems, and certain types of medical equipment.
The longevity of these technologies means that driver support and system-level knowledge are widely available. For OEMs, this translates to improved supply chain stability and easier maintenance or replacement cycles over a product's extended lifespan. By opting for a display like the A056DN01 V6, manufactured by a reputable company like AUO, design teams can focus on their core application logic rather than navigating the complexities of emerging display technologies. This choice prioritizes total cost of ownership (TCO) and operational reliability over cutting-edge specifications, a critical consideration for many non-consumer-facing applications.
Strategic Perspective
The AUO A056DN01 V6 serves as a critical component for designers who prioritize functional integration, reliability, and cost-effectiveness over raw performance metrics. Its value is not in competing with the latest high-resolution displays, but in providing a stable, predictable, and easily integrated visual interface for a specific class of devices. For engineering and procurement teams, this module represents a low-risk solution that fulfills the visual requirements of many specialized applications, ensuring that product development timelines and budgets can be met with confidence. Selecting this display is a strategic decision to leverage mature technology for long-term product stability.
