Excellent Picture Quality

Delta’s outdoor LED series have optimum brightness with a high refresh rate making content clearly visible even in high ambient lighting. A high refresh rate of up to 3840Hz assures smooth content playback and up to 16-bit color processing provides a higher greyscale level, thereby giving a more life-like image.


Optimum Power Consumption

Power consumption has been a major concern for many LED applications, especially those requiring 24/7 operation. Delta LED displays are designed with optimized power supplies to limit power consumption to a minimum. This not only helps you save money but also confirms Delta’s long-term commitment to environmental protection and core focus on green energy-efficient solutions.


Easy On-site Calibration with Your DSLR Camera

LED displays lose uniformity as the LEDs dim over time. With the help of your own DSLR (Digital Single-Lens Reflex) camera, Delta’s built-in on-site calibration technology can automatically adjust the color and brightness of the display to achieve perfect uniformity.


Built for all Weather

The front and back of Outdoor LED cabinets are IP69K / IP669K rated, making them suitable for various outdoor scenarios. The IP rating allows stable operation of LED displays even during extremely harsh environments and virtually any weather conditions.
