Common Cathode Energy-Saving LED Screen

The outdoor common shade energy-saving screen adopts common shade lamp beads and separate power supply, solving the problem of difficult heat dissipation of outdoor display screens from the source. We test outdoor common cathode energy-saving screens (hereinafter referred to as "energy-saving screens") of the same size and spacing with conventional outdoor display screens. Through comparison of white balance tests and temperature tests, we use data to explain where the common cathode energy-saving screen truly "saves energy".

Test objects: P3.8/P4 common cathode energy-saving screen and P3.8/P4 common anode display screen

Test environment: Outdoor

Environmental temperature: 25 ℃

Wind speed: Breeze

Test the temperature change continuously for 10 minutes with a brightness of 3200cd and a white balance of 255;

Test the temperature change after playing the video for 10 minutes.

Note: The test sample uses 1919-NB pure black light beads with a high contrast ratio of 10000:1, which is equivalent to a brightness of about 7000cd for a regular white light.

The temperature data after 5 minutes is as follows:

Product Features

● Unique "energy-saving screen" technology reduces temperature by 30-50% compared to conventional screens, effectively controlling temperature rise and ensuring more stable operation;

● Adopting 2.8V+3.8V dual channel power supply, saving half of the power supply and reducing the failure rate;

● Low power consumption, saving about 30-50% electricity, efficient and energy-saving driving IC, reducing driving circuit losses, and lowering operating costs;

● Low heat, natural heat dissipation without the need for air conditioning, zero noise and more energy-efficient operation, extending the lifespan of the display screen;

● High brightness of cold light sources to better meet the high reliability requirements of outdoor applications;

● Ultra high refresh display, fast frame changing speed, eliminating ghosting without trailing, low brightness and high gray lossless technology, solving industry problems;

● CNC precision machined magnesium aluminum box, 22Kg/㎡ lighter than traditional iron box and 8Kg/㎡ lighter than die cast aluminum;

● Fully sealed magnesium aluminum box design, waterproof, dustproof, anti-corrosion, flame retardant, UV resistant, with a protection level of up to IP65

Application

Kunjing Optoelectronics shared shade screen series adopts new energy-saving technology, reducing temperature by 60% compared to conventional LED displays and saving about 70% energy. It has high refresh rate and high brightness; Configuration P3/P3.8/P4/P5/P5.93/P8/P10 and other different spacing points can be applied in outdoor advertising media, information display, image landmarks, sports venues, commercial real estate, intelligent transportation, smart light poles, outdoor advertising machines, creative displays and other commercial market fields.
