Comparison Table of Core Parameters
Characteristic | Difference explanation | ||
Working temperature | -30°C ~ 85°C | -20°C ~ 70°C | AT070TN94 has a wider temperature range and is suitable for extreme environments |
Brightness | 400 cd/m² (Typ.) | 250 cd/m² (Typ.) | AT070TN94 has 60% higher brightness and better visibility under strong light |
Contrast ratio | 500:1 | 500:1 | The same |
Response time | 25 ms (Tr+Tf) | 10/15 ms (Tr/Td) | AT070TN92 responds faster and has smoother dynamic images |
Backlight current | 170-200 mA | 170-200 mA | The same |
Anti vibration performance | 3.0G | Not labeled (only in accordance with industry standards) | AT070TN94 has clear seismic parameters and is suitable for high vibration vehicle mounted aftermarket scenarios |
power consumption | 226mW (panel)+1.674W (backlight) | 226mW (panel)+1.674W (backlight) | The same |
Analysis of Key Technology Differences
1. Environmental adaptability AT070TN94: Supports a wide temperature range of -30 ° C to 85 ° C, with a clear seismic rating of 3.0G, suitable for harsh environments such as military and field equipment. AT070TN92: Operating temperature -20 ° C~70 ° C, suitable for ordinary industrial scenarios (such as indoor instruments).
2. Optical performance brightness: AT070TN94's 400 cd/m ² brightness is significantly higher than AT070TN92's 250 cd/m ², and it displays more clearly in outdoor or strong light environments (such as car displays). Response time: TN92 responds faster (10ms/15ms), suitable for dynamic image display (such as video surveillance); TN94's 25ms response may have slight ghosting.
3. Both models support 6/8-bit grayscale selection and image flipping function, and are compatible with RGB interface (50pin FPC) 59. But TN94 labeling can be customized with backlighting up to 1000nits or more, suitable for ultra high brightness demand scenarios.
Comparison of application scenarios
Scene | AT070TN94 Recommended Applications | AT070TN92 Recommended Applications |
Industrial control | Mining machine instruments, oil drilling control panel (wide temperature and seismic resistance) | Small HMI, instrumentation (cost sensitive scenarios) |
Onboard equipment | Construction vehicle display screen (high brightness anti glare) | Car rearview system (basic display requirements) |
Consumer Electronics | Outdoor portable devices (such as military handheld terminals) | Digital photo frame, portable DVD (for indoor use) |
Security monitoring | Offshore platform monitoring screen (anti salt spray wide temperature) | Building intercom terminal (static image) |
Selection Decision Guide
Choose AT070TN94: If you need to cope with extreme temperatures (below -30 ° C or above 70 ° C), high-frequency vibration environments (such as armored vehicles, drilling equipment), or ultra-high brightness requirements (such as desert display screens). Choose AT070TN92: If used for conventional industrial indoor equipment, consumer electronics products, and more cost sensitive (AT070TN92 is usually priced 10-15% lower).
Design suggestion:
AT070TN94's backlight can be customized to over 1000nits, suitable for strong light scenes such as aviation and navigation; AT070TN92 paired with 8080 bus driver board (such as STM32 solution) can optimize dynamic display effects and is suitable for video devices.
By accurately matching environmental requirements and performance parameters, the advantages of the two screens can be maximized in different scenarios. If you need specific model specifications or supply chain support, you can further consult product information.
