What is Energy-saving LED Display Screens & Price?

LED display screens have the advantages of high brightness, high color saturation, and clear display. They are widely used in various scenarios. Since LED display screens need to work continuously for a long time, energy saving has become a major focus of everyone’s purchase. So What is energy-saving LED display and how to choose aa good energy-saving LED display screen?

What is an Energy-Saving LED Display?  

An energy-saving LED display is a modern, efficient digital display. It uses less power compared to traditional LED screens. Combine advanced technology, these screen can reduce energy consumption. They maintain high brightness and excellent visual performance. Businesses use them to lower costs and promote sustainability.  

Energy-saving LED displays come in various types, including indoor, outdoor, and transparent designs. They are ideal for advertising, events, and public spaces.

Key features of energy-saving LED displays:  

  • – Uses up to 50% less energy than standard LED screens.  
  • – Maintains vivid images even in direct sunlight.  
  • – Energy-efficient drivers and optimized power supply.  
  • – Durability and reduced maintenance.  
  • -Built with recyclable and sustainable components.  
  • – Wide application for indoor and outdoor settings.  
  • – Adjusts brightness automatically to save energy.  
  • – Reduced heat generation.

How does LED display screen save energy?

According to power P=current * voltage U, under the same brightness, energy saving can be achieved by reducing current or voltage. At present, the energy-saving methods are achrived by follows:

  • 1)Use high-brightness LED lamps to reduce the current of the unit board to achieve energy saving.
  • 2)Match with energy-saving power supply to reduce the power supply of the display unit to achieve energy saving.
  • 3)Equipped with brightness sensor, the brightness of the screen body changes with the environment, reduce the current of the screen body, and achieve energy saving.
  • 4)Match with dynamic energy-saving PWM-SS driver chip, so that the chip works according to the quality of the screen picture, reduce the current of the screen body, and achieve dynamic energy saving.

Among them, one and two belong to static energy saving, three and four belong to dynamic energy saving. Static energy saving and dynamic energy saving are the two major energy-saving technologies in LED display screens.

What are static energy saving and dynamic energy saving?

Static energy saving technology

Static energy saving technology refers to the technology that achieves a fixed energy saving ratio through design or hardware. For example, the LED display can save 10% energy by using a 4.5V switching power supply compared to using a 5V switching power supply. This fixed energy saving ratio technology is static energy saving technology.

Dynamic energy saving technology

Dynamic energy saving technology refers to the technology that achieves a non-fixed energy saving ratio through design or hardware. The energy saving ratio changes according to the picture situation. For example, using a brightness sensor to control the brightness of the screen is a dynamic energy saving technology.

If LED display is equipped with a 4.2V switching power supply, it can achieve static energy saving and dynamic energy saving. With a comprehensive energy saving of 30%-45%. The specific performance of dynamic energy saving is as follows:

Intelligent screen off energy saving.

When the LED display is black (no power outage), the dual energy-saving driver IC will automatically enter the sleep state. For example, when playing a slide with only text, the text is white and the other areas are black. At this time, only the text display area consumes power.

Energy saving due to light and dark changes.

The dual energy-saving driver IC will automatically adjust the current according to the light and dark changes of the display screen. The lower the brightness of the playback screen, the less power consumption.

Energy saving due to color changes.

The dual energy-saving driver IC can automatically adjust the current according to the richness and saturation of the displayed image colors. For example, when switching from a colorful image to a dimly colored image, the power consumption of the display will automatically decrease.

More Option:

Choose environmentally friendly materials.

If the LED display screen made of environmentally friendly materials,it can achieve the purpose of waterproof, dustproof and UV protection through special processing technology without glue filling. It consumes less materials than products produced by general processes and is more environmentally friendly.

Multi-level grayscale correction technology

Ordinary LED display systems use 18-bit color display levels, so in some low grayscale and color transitions, the colors will be displayed very stiffly, which will cause color light discomfort. The new large-screen LED control system uses a 14-bit color display level, which greatly improves the hardness of the color transition, making people feel soft colors when watching, and avoiding people’s discomfort with light.

Strong convection heat removal system

Using stabilize the heat dissipation system LED display screens will release more 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. In order to ensure the normal operation of the LED screen in a stable environment, it is necessary to strengthen the heat dissipation system of the LED display screen.
