What are the energy saving and environmental protection methods for LED transparent screen?

If a large transparent LED screen is installed, for example, some shopping malls have a large area. When a huge transparent LED screen is erected from top to bottom, it may reach dozens of square meters. The large transparent display consumes The power is naturally very large.

From the perspective of power consumption, although the luminescent materials used in the LED display itself are energy-saving, some of them need to be used in occasions with a large display area. Due to long-term use, the overall power consumption is still relatively large. The required brightness will be relatively high. Under the effect of these comprehensive factors, the power consumption of the LED flexible screen is quite astonishing, so the electricity bills borne by the advertising owners will also increase geometrically.

It is also inconsistent with the current practice of the “low-carbon environmental protection” concept. So, what energy-saving and environmentally friendly methods for LED transparent screens to help us reduce power output? Let’s take a look at the relevant content together.

Energy-saving method of LED transparent screen

First, adopt an adjustment system that can automatically adjust the brightness

Depending on the day and night, in different locations and time periods, a slight change in the brightness of the display screen will have a great effect. If the playback brightness of the LED transparent screen is greater than 50% of the ambient brightness, although the colors are bright, we will obviously feel discomfort to the eyes, which will cause “light pollution” invisibly.

If we install a brightness collection system in the LED transparent screen, we can collect light according to the surrounding brightness at any time, and use the display control system to receive system data and automatically convert it to the brightness suitable for the environment through the software to broadcast the screen. A bit similar to the principle of light-sensing lighting, except that the information and content processed by the LED transparent screen are more complicated, but the corresponding accuracy and functions are also more.

Second, multi-level grayscale correction technology

Ordinary LED display systems use 18bit color display levels, so in some low grayscale and excessive color, the color will be displayed very bluntly, so it will cause the color light to be unsuitable. The new LED large screen control system uses a 14-bit color display level, which greatly improves the hardness of the color overlying, so that people feel the color soft when watching, and avoid people’s discomfort to light.

Since the color display level is 4bit less than the original 18bit, after several calculations on the LED display and the average value, it is found that the power consumption of 14bit is 23% less than that of 18bit. Therefore, the 14bit LED display will obviously save more power. .

In addition to the two methods mentioned above, there are the following tips on energy saving and environmental protection:

1. It is possible to use high-efficiency LED lights and the light-emitting chip does not cut corners. In this way, not only the service life is longer, but also the performance of high-efficiency LED lights will be better under the same brightness;

2. The use of high-efficiency switching power supply greatly improves the power conversion efficiency, and does not allow excess energy consumption to be wasted;

3. The excellent heat dissipation design of the screen can increase the heat conduction of the copper pipe, thereby reducing the power consumption of the fan;

4. Design a scientific overall circuit plan to reduce the power consumption of internal circuits;
