How to Select a Screen for Ultrasonic Flaw Detectors? LEEHON Technology Guides You: A Comprehensive Evaluation of AUO G057QN01 V2 & G057VN01 V2 (Updated May 2025)

Selecting the right display screen for your ultrasonic flaw detector is crucial. This report, presented by Hangzhou LEEHON Technology Co., Ltd. (LEEHON Technology), will delve into two core LCD screens from AUO, the G057QN01 V2 and G057VN01 V2. We will evaluate how their key features, such as wide temperature range and high brightness, meet the demanding requirements of industrial scenarios. Additionally, we will combine LEEHON's professional services and stable supply capabilities to provide you with a comprehensive selection strategy.

Executive Summary: AUO's G057QN01 V2 (QVGA) and G057VN01 V2 (VGA) can both meet the demanding requirements of ultrasonic flaw detectors in terms of wide temperature range (-30°C to 85°C) and high brightness (800 cd/m² and 700 cd/m² respectively).^^ The G057QN01 V2 offers higher brightness and slightly lower power consumption (typical 3.34W) ^^, while the G057VN01 V2 has an advantage in displaying complex data with its VGA resolution (typical total power consumption 3.74W).^^ Hangzhou LEEHON Technology Co., Ltd. (LEEHON), as an authorized distributor for leading global LCD screen brands like AUO, not only ensures a stable supply of these high-quality panels but also provides a full range of services from selection consultation to customized solutions.^^ The final choice should balance your equipment's specific needs for data detail and power consumption, and LEEHON will assist you throughout the decision-making process.

I. Why is the Screen Selection for Ultrasonic Flaw Detectors So Critical?

The operating environments for ultrasonic flaw detectors are often complex and varied, placing extremely high demands on the performance and durability of their display screens. Understanding these needs is the first step in making the right selection and forms the basis of LEEHON's professional advice.

Interpreting Environmental Requirements:

• Wide Temperature Operation is Fundamental: Flaw detectors are frequently used outdoors, in high-temperature factory floors, or in low-temperature warehouses, experiencing drastic temperature fluctuations. For example, some detectors specify an operating temperature range of -10°C to +40°C ^^, or -15°C to +50°C ^^, with specific applications requiring -10°C to +45°C.^^ Industrial-grade display screens typically support a wider range of -20°C to +70°C ^^, or even -30°C to +85°C as seen in our featured AUO screens.^^ LEEHON understands that the "wide temperature" characteristic is crucial for ensuring reliable equipment operation in diverse industrial scenarios such as weld, forging, and steel plate inspection.^^
• Protection Rating Cannot Be Ignored: Industrial environments are often dusty and humid, so equipment typically needs dust and moisture resistance.^^ Some flaw detectors have an IP65 protection rating ^^, or even an IP67 design target.^^ While the display screen itself does not have an IP rating, its integrated design must meet the overall protection requirements of the machine, and LEEHON can provide relevant integration advice.** **

Core Performance Indicators:

• High Brightness Ensures Readability: "Sunlight readable" is key for operation outdoors and in high-ambient light environments.^^ Standard industrial screen brightness is around 350 cd/m² ^^, but outdoor applications require higher brightness, for example, greater than 700 nits.^^ The display's brightness and surface treatment (such as anti-reflective coating and optical bonding ^^) directly impact operator efficiency and accuracy. LEEHON can provide high-brightness and optical bonding customization solutions.^^
• Balancing Resolution and Size: Portable non-destructive testing (NDT) equipment screen sizes range from 3.7 inches ^^ to 5.7 inches ^^, 7 inches ^^, and even larger, up to 14 inches.^^ The resolution must be sufficient to clearly display A-scan, B-scan, and other detection data.^^ The 5.7-inch AUO screens are a common size, balancing portability and information density.** **
• Durability Guarantees Equipment Lifespan: Industrial instruments must withstand physical shock and vibration. General industrial display screens are designed for this.^^ Some panels provide vibration level parameters such as 1.5G (14.7 m/s²).^^

Interface and Power Consumption Considerations:

• Interface Choice Affects Integration: CMOS/Parallel RGB (TTL) ^^, LVDS ^^, and MIPI ^^ are common interfaces for small industrial screens. These two AUO screens use a CMOS interface, which requires careful design to ensure signal integrity and electromagnetic compatibility. LEEHON can provide relevant technical support.^^
• Power Consumption Affects Battery Life: For portable, battery-powered flaw detectors, low power consumption is crucial.^^ Many flaw detectors aim for a battery life of around 10 hours ^^, making screen power consumption a core selection criterion.** **

II. AUO G057QN01 V2 vs. G057VN01 V2: LEEHON Explains the Core Models

Hangzhou LEEHON Technology (LEEHON) highlights and provides a detailed analysis of AUO's G057QN01 V2 and G057VN01 V2, two 5.7-inch industrial-grade LCD screens. These models, with their excellent performance, are ideal choices for ultrasonic flaw detectors.

A. G057QN01 V2 (QVGA) Detailed Specifications and Applicability Analysis

The AUO G057QN01 V2 is a 5.7-inch a-Si TFT-LCD module specifically designed for industrial applications.

Table 2: AUO G057QN01 V2 Key Specifications (Supplied by LEEHON)

Applicability Interpretation (LEEHON Recommendation): The G057QN01 V2 excels in brightness and operating temperature, fully meeting the core "wide temperature, high brightness" requirement. Its 800 nits high brightness ensures visibility outdoors and in harsh industrial environments. Its lower power consumption (3.34W) ^^ is beneficial for battery life. The QVGA resolution is suitable for displaying simple data and basic graphical interfaces. If your flaw detector does not require high information density but has an utmost pursuit of brightness and power efficiency, LEEHON recommends this model.** **

B. G057VN01 V2 (VGA) Detailed Specifications and Applicability Analysis

The AUO G057VN01 V2 is also a 5.7-inch industrial-grade a-Si TFT-LCD module, but it offers a higher resolution. LEEHON also ensures its stable supply.

Table 3: AUO G057VN01 V2 Key Specifications (Supplied by LEEHON)

Applicability Interpretation (LEEHON Recommendation): The main advantage of the G057VN01 V2 is its VGA resolution, with four times the pixel count of QVGA, allowing for clearer display of complex defect data and advanced user interfaces. Although its brightness (700 nits) is slightly lower than the former and power consumption (3.74W) ^^ is slightly higher, LEEHON believes this screen is a better choice for flaw detectors with higher requirements for information density and image clarity. A brightness of 700 nits still performs excellently in most industrial scenarios.** **

C. Core Parameter Comparison of the Two Screens: LEEHON Helps You Decide

Table 4: AUO G057QN01 V2 vs. AUO G057VN01 V2 Specification Comparison (LEEHON Supply Guarantee)

Selection Advice (LEEHON Perspective): If the flaw detector needs to display fine waveforms or complex menus, the G057VN01 V2 (VGA) is more suitable. If the equipment pursues ultimate portability, is power-sensitive, and has simple graphical requirements, the G057QN01 V2 (QVGA) has a slight advantage in brightness and power consumption. Both perform excellently in terms of durability, and LEEHON can provide a stable supply and technical support for both.
