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 5880Hz 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.
