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;

What are the technologies in the LED display lamp beads?

The application of LED display is very wide, and besides the control system, power supply and other accessories, the most important thing is still the LED lamp beads. This is like a computer without a display, even if the host is in a powerful way, it will not play any role. of. So today we will talk about LED lamp beads. At present, the luminous color and luminous efficiency of LED lamp beads are related to the materials and processes used to make LEDs. Different materials used to make LEDs can generate photons with different energies, thereby controlling the wavelength of the light emitted by the LED, that is, the spectrum or color. The currently known technologies mainly include the following: 1. Transparent substrate technology InGaAlP LEDs are usually prepared by epitaxially growing InGaAlP light-emitting areas and GaP window areas on a GaAs substrate. Compared with InGaAlP, GaAs material has

What problems may be faced by LED display screens produced by inferior LED display manufacturers?

With the rapid development of the automobile market in recent years, more and more green-brand cars can be seen on the road. These green-brand pure electric cars are jokingly called “electric fathers” by netizens. The reason for this title is that the car is originally an improved product that improves the convenience of our lives. It can liberate our legs and go anywhere anytime; However, due to the limitation of cruising range and imperfect charging facilities, electric vehicles have brought huge inconvenience to the daily use of car owners. Aside from the inconvenience of daily charging, even the necessary cold and warm air conditioning in winter and summer must be considered as car owners. Use it to give priority to ensuring the supply and guarantee of limited electric energy for driving mileage. As a travel tool, car owners cannot enjoy a convenient and comfortable driving experience. Like electric vehicles, LED

P0.7 or P0.9 small-pitch LED display which is more popular with people

Small-pitch LED display have been available for many years. As the most potential competitor in large-screen displays, small-pitch LEDs have replaced some of the DLP and LCD markets, and more and more are widely used in various industries. middle. With the development of science and technology, the small pitch of commercial applications has been promoted step by step from P2.5 to P1.0 to P0.7, and companies have launched small pitch products with the smallest known performance at P0.4mm. SMD and COB must be a topic that cannot be avoided when it comes to the technology update of small pitch. As we all know, in the small-pitch LED display industry, the SMD label market is relatively mature, and the COB small-pitch can only be said to be a rising star for various reasons. With 0.7mm pitch, it can display 2K resolution images on a 61-inch area. Such a display effect is

The advantages and disadvantages of COB packaged LED display and its development difficulties

COB packaging is a major advancement in LED displays in recent years. Thanks to the development of COB packaging technology, the dot pitch of displays is getting smaller and smaller. At present, high-end LED manufacturers have achieved 0.4mm dot pitch, but The problem is also very obvious. After all, there are some technical barriers, so the price is still relatively high. COB packaging integrates upstream chip technology, midstream packaging technology and downstream display technology. Therefore, COB packaging requires close cooperation between upstream, midstream and downstream companies to promote the large-scale application of COB LED displays. As shown in the figure above, it is a COB integrated packaged LED display module. The front side is composed of LED lamp modules to form pixels, and the bottom side is an IC driving element. Finally, each COB display module is spliced ​​into a design-sized LED display. The theoretical advantages of COB: 1. Design
