A brief discussion on how to make LED display screens more energy-saving?

With the rapid development of society, all walks of life are also advocating the manufacture of green and environmentally friendly products, and the LED industry is no exception. LED display screens have been widely used in every street corner of the city and have become a unique symbol that enhances and beautifies the image of the city. The LED industry should keep pace with the times, respond to calls, and promote energy-saving and environmentally friendly products.cog led It is well known that LED displays may not achieve ideal results in terms of energy saving due to their high brightness, but this does not mean that they must be high-energy-consuming products. So how can LED displays be more energy efficient? Let me talk about it below.

1. Choose environmentally friendly materials

The LED display screen made of environmentally friendly materials can be made waterproof, dustproof,outdoor lcd digital signage and UV-resistant through special processing technology without the need for glue filling. Products produced by ordinary processes require less consumables and are more environmentally friendly.

2. Adopt an adjustment system that can automatically adjust the brightness

During the day and night, in different locations and time periods, slight changes in the brightness of the display will have a huge effect.ips vs ads panel If the playback brightness of the LED display is 50% greater than the ambient brightness, we will obviously feel eye discomfort, which will cause "light pollution".

We can collect the ambient brightness at any time through the outdoor brightness collection system, and use the display control system to receive system data and automatically convert the software to a brightness suitable for the environment for broadcasting.

3.Constant current noise reduction technology

The LED display driver chip adopts the internationally advanced LED display dedicated chip system, which is the leading manufacturer in the field of full-color LED displays. Combined with its chip characteristics, constant current noise reduction technology has been developed to ensure that the impact of other noise sources such as power supply on the LED electronic display is minimized. Some driver ICs can also save energy from the original 5V voltage to 4.2V to achieve energy-saving functions.

4.Multi-level grayscale correction technology

Ordinary LED display systems use 18-bit color display levels, so in some low grayscale and excessive color areas, the color will be displayed very bluntly, thus causing color light incompatibility. The new LED large-screen control system uses 14-bit color display levels, which greatly improves the hardness of colors, making people feel soft colors when watching, and avoiding people's discomfort with light.

5. Strong convection heat dissipation system makes the heat dissipation system stable

The LED display screen will release a lot of heat after working for a long time. If the heat is not dissipated in time, it will cause a certain degree of damage to the screen body and affect the normal use of the screen. In order to ensure that the display screen operates normally in a stable environment, it is necessary to strengthen the heat dissipation system of the LED display screen.

6.Power supply

The realization of LED energy-saving display screen mainly starts from the power supply. Directly using half-bridge or full-bridge high-efficiency switching power supply on the existing LED display screen, combined with synchronous rectification, has significant energy-saving effect. Reduce the power supply voltage as much as possible under the constant current state of the driver IC, and achieve better energy-saving effects by separately supplying power to the red, green, and blue dies.

If the selection of LED display screens can start from the aspects of material selection, brightness adjustment, noise reduction processing, heat dissipation improvement and power supply, then LED display screens can also make their own efforts in energy conservation and environmental protection.
