AUO G057QTN01 V2 and Sharp LQ057Q3DC12

The AUO G057QTN01 V2 and Sharp LQ057Q3DC12 are both 5.7-inch TFT-LCD displays suitable for industrial applications due to their durability and reliability in various conditions. However, they differ in resolution, brightness, and a few other technical parameters, which may influence your choice depending on your specific use case.

AUO G057QTN01 V2 Overview

The AUO G057QTN01 V2 offers a 5.7-inch display with a resolution of 320×240 (QVGA) and uses LED backlighting. It is designed for industrial environments, with a wide operating temperature range from -30°C to 85°C. The LED backlight provides a brightness of 500 cd/m². Its LED design also contributes to a longer lifespan and lower power consumption compared to older CCFL backlit displays​.

Sharp LQ057Q3DC12 Overview

Similarly, the Sharp LQ057Q3DC12 also offers a 5.7-inch TFT-LCD panel with a 320×240 (QVGA) resolution. However, it uses a CCFL (Cold Cathode Fluorescent Lamp) backlight with a brightness of 500 cd/m². The operating temperature range is comparable, extending from -30°C to 80°C, slightly lower than the AUO model. The display also supports RoHS compliance, ensuring it meets environmental standards.

Key Differences

1. Backlighting: The most significant difference lies in the backlighting technology. The AUO G057QTN01 V2 uses an LED backlight, which is more energy-efficient and has a longer lifespan compared to the CCFL backlight used in the Sharp LQ057Q3DC12. This makes the AUO model more suitable for applications where long-term usage and lower maintenance are priorities.
2. Operating Temperature: While both models offer wide operating temperature ranges, the AUO G057QTN01 V2 provides slightly better thermal performance with an upper limit of 85°C, compared to 80°C for the Sharp LQ057Q3DC12.

Applications

The AUO model’s LED backlight will generally require less energy and have a longer lifespan, whereas the Sharp model with CCFL backlighting may have higher energy costs over time due to the nature of the technology.

Conclusion

When selecting between the AUO G057QTN01 V2 and the Sharp LQ057Q3DC12, it’s important to consider the long-term benefits of LED versus CCFL backlighting, as well as any specific environmental factors that may affect operating temperatures. Both displays are excellent for industrial applications, but the AUO G057QTN01 V2 may provide better value due to its longer lifespan and lower power consumption.
