AUO G084SN05-V9, G084SN05-V7, and G084SN05-V3 LCD modules

Overview of Specifications

Detailed Comparison

Brightness and Contrast

• G084SN05-V9 and V7: Both offer a brightness of 450 cd/m² and a contrast ratio of 600:1, making them suitable for environments requiring good visibility and image clarity.
• G084SN05-V3: Slightly lower brightness at 400 cd/m² and a contrast ratio of 500:1, which might not be as bright or sharp as the V9 and V7 models.

Viewing Angle

• G084SN05-V9 and V7: Both models provide wide viewing angles of 160° horizontally and 140° vertically, suitable for applications where the display needs to be viewed from various angles.
• G084SN05-V3: Offers narrower viewing angles of 120° horizontally and 100° vertically, which could be a limitation in some applications.

Operating and Storage Temperature

• G084SN05-V9 and V7: Both models can operate in extreme temperatures ranging from -30°C to 85°C and can be stored in similar conditions, making them ideal for industrial and harsh environments.
• G084SN05-V3: Has a more limited operating temperature range of 0°C to 50°C and a storage range of -20°C to 60°C, making it less versatile for extreme conditions.

Backlight Type

• G084SN05-V9: Uses an LED backlight, which is generally more energy-efficient and has a longer lifespan compared to CCFL.
• G084SN05-V7 and V3: Both use CCFL backlights, which may consume more power and have different maintenance requirements compared to LED backlights.

Replacement Considerations

• Compatibility: The G084SN05-V9 and V7 are more closely matched in terms of brightness, contrast ratio, and wide operating temperature range, making them more suitable replacements for each other.
• Application Requirements: If your application requires extreme operating conditions and wide viewing angles, the V9 and V7 models are preferable. The V3 might be suitable for less demanding environments but with potentially lower display quality and operational flexibility.
• Backlight Technology: The choice between LED (V9) and CCFL (V7, V3) could affect power consumption, maintenance, and overall longevity. LED backlights generally offer better efficiency and longer life.

In conclusion, while the G084SN05-V9 and V7 can be considered interchangeable for most applications due to their similar specifications, the G084SN05-V3, with its narrower viewing angles and lower brightness, may not be an ideal substitute in all cases. However, for applications with less stringent requirements, the V3 can still be a viable option.
