The product specification defines this module with a 31.5 inch active display area, 1920 × 1080 resolution, 2500 cd/m² minimum center brightness and 3700 cd/m² peak brightness. It also supports 178° viewing angles, anti-glare surface treatment, portrait and landscape installation, and commercial display operating conditions.
One of the most important advantages of this TFT LCD module is its MiniLED backlight system. The module achieves up to 3700 cd/m² peak brightness, making displayed content easier to read under sunlight and strong ambient lighting conditions.
High brightness is essential for outdoor digital signage, transportation displays, public information systems, and retail advertising terminals where standard LCD modules may suffer from poor readability.
The MiniLED backlight design improves light control efficiency while maintaining excellent image quality. This allows system manufacturers to develop displays that deliver clear content visibility without requiring excessive display power.
The integrated MiniLED backlight adopts a COB (Chip on Board) structure with advanced LED control technology. The backlight system includes 1152 independent local dimming blocks, enabling accurate brightness adjustment in different display areas.
With local dimming control, dark areas can be reduced while bright areas remain highly visible. This improves dynamic contrast performance and creates more detailed images, especially when displaying high-quality advertisements, videos, and interactive content.
The specification indicates that the MiniLED backlight supports dynamic contrast enhancement through individually controlled dimming zones, improving brightness and contrast optimization based on image content.
The MiniLED backlight board uses COB packaging technology, where LED chips and driver IC components are integrated on an aluminum-based board. This structure helps improve thermal performance and reliability.
The MiniLED system contains 2304 LED units and 1152 blocks, with two LEDs assigned to each block for precise brightness control.
Compared with traditional LED backlight solutions, MiniLED technology provides better heat management, improved brightness uniformity, and enhanced optical performance.
The display module provides a wide viewing angle of 178 degrees horizontally and vertically, allowing multiple viewers to see consistent image quality from different positions.
This feature is particularly important for public displays installed in shopping centers, transportation areas, exhibitions, and other environments where viewers approach the display from different angles.
The ADS LCD technology used in this module provides low color shift performance, ensuring stable image reproduction in commercial applications.
The module supports both landscape and portrait installation modes, providing flexibility for different product designs.
Manufacturers can integrate this display solution into various commercial systems, including wall-mounted displays, digital kiosks, advertising machines, and public information terminals.
The mechanical design supports heat sink integration, making it suitable for applications requiring continuous operation and thermal management.
Outdoor advertising systems require displays with strong brightness, reliable operation, and excellent readability. The 3700 nits MiniLED backlight makes this module suitable for outdoor digital signage where sunlight readability is critical.
Typical applications include outdoor advertising kiosks, shopping mall outdoor displays, and public advertising terminals.
The module is designed for Public Information Display (PID) applications. Its high brightness, wide viewing angle, and long operating lifetime make it suitable for information boards installed in public environments.
Applications include transportation information displays, building information systems, and visitor guidance terminals.
Retail and commercial environments require displays that attract attention through high-quality images and vivid colors.
The MiniLED backlight technology improves visual impact by enhancing contrast and brightness, making it suitable for advertising displays, brand promotion screens, and interactive commercial terminals.
The MiniLED backlight provides high brightness while supporting power-efficient operation compared with traditional high-power backlight solutions.
This makes it suitable for manufacturers developing energy-conscious outdoor display products.
