How to make full-color LED display screens energy-efficient?

Green environmental protection has long been a major theme at present, and society is developing. However, environmental pollution is also expanding at any time, so humans must protect our homeland. Currently, various industries are also advocating the manufacture of green environmental products. So, how LED companies can develop full-color LED display screens that do not produce light pollution or non electric energy has become an important product performance that consumer companies must deal with.

LED display screens were once widely used on various street corners in cities, becoming a common symbol to enhance the city’s image. However, while beautifying the city’s image, the strong light on the screen also has a certain negative impact on the nighttime life of urban residents. The LED industry is a “dimming” industry, and the screen “mountain light” is understandable. However, from the perspective of urban environmental pollution prevention, it has once become a new type of pollution “valguse saastamine”. Seetõttu, enterprises should pay attention to the issue of “valguse saastamine” in consumption and control the brightness settings well.

1. Adopting an automatic brightness adjustment system

Depending on the day and night, as well as the location environment and time zone, some changes in display brightness can have a significant effect. When the regenerative brightness of a full-color LED display screen is greater than 50% of the ambient brightness, it will cause obvious discomfort to the eyes and form “valguse saastamine”.

Then, through the outdoor brightness collection system, the environmental brightness collection can be stopped at any time, and the LED display control system can be applied to receive system data and automatically switch to the appropriate environmental brightness through software to stop broadcasting.

2. Multi level grayscale correction technology

A regular full-color LED display system uses an 18 bit color display layer, so if there is low grayscale and excessive color, the color will appear stiff, resulting in a lack of coordination in colored lighting. The new LED large screen control system adopts a 14 bit color display level, greatly improving the excessive color hardness, making people feel the color is gentle when watching, and preventing the discomfort of light.

In terms of power consumption, full-color LED displays themselves use energy-saving luminous data, but some display areas need to be applied to larger areas. If used for a long time, the total power consumption is still very high. Because the required brightness is relatively high. Under the influence of these composite factors, the power consumption of the display is quite astonishing. So all the electricity bills borne by advertisers will also increase exponentially. Seetõttu, enterprises can save energy through the following 5 punkt.

(1) High efficiency LEDs can be used, and the light-emitting chips do not cut corners.

(2) Using efficient switching power supplies greatly improves power conversion efficiency.

(3) Stop the excellent screen cooling design and reduce fan power consumption.

(4) Design a scientific overall circuit plan to reduce internal circuit power consumption.

(5) Automatically adjust the brightness of outdoor display screens according to changes in the external environment to achieve energy-saving and emission reduction effects.
