What kind of display is the energy-efficient qualified display?

With the increasing emphasis on energy conservation and environmental protection in countries around the world, the field of energy-saving, environmentally-friendly and efficient LED display has gradually become a market demand, and major companies have joined the ranks of energy-saving display. It is worth noting that the pursuit of energy-saving effects by enterprises was originally a good thing for the benefit of the country and the benefit of the people, but overemphasizing the concept of energy conservation and neglecting the specific practicality, the theory of energy conservation has become overkill.

In the future, energy-saving displays are qualified displays, and the significance of energy conservation is not only the efforts of display manufacturers, but also the perception of the entire industry, especially the help of related device companies.

The need for energy saving

The need for energy saving in LED displays is self-evident. Energy conservation is not only an important strategic measure for national energy conservation and emission reduction, but also a necessary way for the long-term development of the LED display industry. Enterprises advocate the concept of energy conservation, which is conducive to setting industry benchmarks and improving the high-end performance of products.

If a 100-square-meter LED display saves one kilowatt-hour per day, then 365 kWh of electricity is saved 365 days a year, and the electricity is calculated at 1.5 yuan per kilowatt hour. Then an LED display can save electricity costs by 547.5 yuan per year. If energy-efficient LED displays are promoted across the country, the energy and electricity savings will be a huge sum of money.

Energy saving is a hot topic at the moment of LED display. Energy saving can save electricity, but saving electricity is not the same as saving energy. Therefore, first of all, it is very important to understand the concept of energy conservation.

Several concepts of energy saving

[Power saving is a form of energy saving, but saving electricity does not mean energy saving. High brightness is also a kind of performance of LED display energy saving, and some manufacturers are partial, and the higher the brightness, the more energy-saving. The release of this signal obviously confuses people's true understanding of energy saving. 】

Energy saving and power saving

Energy conservation refers to the strengthening of energy management, the adoption of technically feasible, economically sound and environmentally and socially affordable measures to reduce losses and waste from energy production to consumption, and to use energy more efficiently and rationally. Saving electricity is only a concrete manifestation of energy saving, but energy saving represents a broader meaning. Saving electricity means saving electricity. Saving electricity is not using electricity, using less electricity, but using electricity. Take technically feasible and economically reasonable measures to reduce direct and indirect losses of electrical energy, improve energy efficiency and environmental protection.

LED display energy saving mainly includes reasonable design, reasonable configuration, brightness compensation, point-by-point brightness and color correction, etc., which not only prolongs the service life of the screen, but also maintains the beautiful effect of the screen, and saves unnecessary for customers. High maintenance costs and operating costs.

Energy saving and brightness

In order to achieve energy-saving effects, many companies emphasize the effort to achieve brightness. Energy saving is not equal to saving electricity, and energy saving is not equal to high brightness.

High brightness is also a kind of performance of LED display energy saving, and some manufacturers are partial, and the higher the brightness, the more energy-saving. The release of this signal obviously confuses people's true understanding of energy saving.

In order to achieve high brightness, screen companies began to pursue large-size chips. At present, the more popular 12000 cd/m2 high-brightness LED lamps in China basically use large-size LED chips . To get such a high brightness, you can only increase the drive current. However, high-brightness LED lamps are inevitably accompanied by high attenuation and low stability. High attenuation is not conducive to the long-term use of LED display, but also becomes a congenital defect that excessively pursues high brightness, and this inherent defect will damage the life and picture effect of LED display all the time.

In addition, there is still a problem that is difficult to ignore in high brightness - light pollution. Especially for outdoor LED displays, the high brightness is easy to affect people's visual viewing, and even become the object of people's complaints. In order to avoid the problem of light pollution, LED display screens generally set different brightness during daytime and nighttime. When the brightness is reduced, the gray level will be affected. The brightness is reduced and the gray level is lost. The greater the brightness adjustment, the more serious the gray level loss. For example, the initial brightness value of the LED display during the day is set to 12000 cd/m2, and when the brightness is reduced to 800 cd/m2 at night, the gradation is extremely lost, so that the night picture quality becomes poor; or the brightness cannot be adjusted to the nighttime use. Standard requirements, and the formation of heavy light pollution.

Excessive pursuit of high brightness is not a true embodiment of energy-saving display. How to ensure a harmonious and stable relationship between brightness and energy saving of LED display is a difficult technical activity. When international giants Carey promotes their display packaging devices, it emphasizes the relationship between high brightness and high efficiency, and achieves energy saving effects while not damaging the gray level while achieving acceptable brightness standards.

Of course, in addition to brightness and power saving, the energy-saving pursuit of LED display also needs to drive IC, Switching Power Supply, product power consumption design, intelligent energy-saving system design and structural energy-saving design. Only by finding the best balance of these aspects can you achieve the best energy savings.
