LED display technology analysis of dangers behind
In the outdoor media market, LED display has become a popular display terminal due to its strong luminous brightness and support for automatic brightness adjustment, and the display content is still clearly visible when the sun shines directly on the screen surface within the visual distance. Brightness, failure is also brightness.” As people’s complaints about light pollution from LED screens continue to increase, many places have issued management regulations for LED displays in public places, and large cities such as Shanghai and Guangzhou are on the list. The threshold for outdoor applications of LED displays has been greatly improved.
In order to rectify problems such as light pollution, the approval of large-screen outdoor installations is becoming more and more difficult, which means that high-quality installation locations are becoming more and more scarce. It’s not getting easier. When outdoor applications are not enough to support the growth of performance, LED display manufacturers turn their attention to the indoor application market that was previously unattainable, and the improvement of LED display technology has become the confidence to enter.
The indoor space is limited, and the traditional LED display has the disadvantage of strong graininess when viewed at close range. Compared with products such as liquid crystal and plasma with delicate screen display, it will not become the first choice for users. However, with the rapid rise of small-pitch LED displays, this shortcoming has been effectively made up for. The improvement of the screen display effect makes the LED display qualified to challenge large-screen display products such as LCD and DLP, and the indoor market has naturally become the focus of many manufacturers.
However, the technical threshold of small-pitch LED displays is relatively high, and the cost of use is relatively high. At this stage, whether from the production level or from the application level, LED advertising machines with low use costs and large shipments have become most LED manufacturers. the best choice.
Relying on the inherent advantages of the LED display, compared with the traditional LCD advertising machine, the LED advertising machine has many advantages in the outdoor environment. For example, the screen brightness of LED advertising machine can reach 5000cd/m2. In outdoor environment, both in coverage and display effect, it is better than LCD advertising machine.
Relevant studies have found that in the past year, although the share of LED displays in the outdoor application market has shown a growing trend, the driving force for the growth is not the increase in the number of screens, but the value-added of the original screens. This also means that with the increase in application market demand, the traditional extensive business model has been unable to promote the development of the industry. If the LED display industry wants to maintain stable growth, it must take a refined route and refine market applications. The development of the indoor application market by LED display manufacturers and the strong investment in outdoor advertising machines is a new attempt to this change.
Referring to the development track of LCD, plasma and other display products, in the large-screen display industry, when the technology develops to a certain stage, refined service has become the key to success or failure, and the LED display industry is no exception. Some people in the industry believe that with the continuous improvement of LED display technology, the provision of specialized solutions will become the key for LED display manufacturers to gain a foothold.
