The principle of LED electronic display screen to display images is mainly to convert digital signals into image signals and present them through the luminous system.
The traditional method is to use video capture card and VGA card to realize the display function. The video capture card is mainly used to capture video images and obtain the index addresses of line frequency, field frequency and pixel points with the help of VGA. The way to obtain digital signals is mainly by copying color look-up tables. Generally, software can be used for real-time replication or hardware theft, which is more efficient than hardware theft.
As people's material life continues to improve, so does their spiritual and civilized life. Beautiful things can promote people's physical and mental happiness. And the urban landscape display lighting project often brings colorful scenery to people, and even becomes a resort for people to punch cards. In recent years, landscape display has become an indispensable part of the night tour economy, and has brought many beautiful and novel audio-visual feast for people.
It can be said that LED display will become the mainstream of landscape display in the future.
"From mobile phones, televisions, street billboards, cinemas, to medical and industrial fields, display technologies are ubiquitous in people's lives today." Li Hongtao, vice president of Konka Group, introduced in an interview with this newspaper that the screen display technology has been continuously optimized and upgraded. Micro LED (Micro Light Emitting Diode) technology has the characteristics of high authenticity, interaction and personalized display, which can cover handheld devices, wearable devices, vehicle mounted displays, super large screens, etc., allowing users to experience the exquisite enjoyment of ultra-high definition images anytime and anywhere.
The traditional LED display screen is mainly rectangular, but it is easy to cause aesthetic fatigue. To this end, LED display manufacturers have increased their R&D and innovation efforts, constantly optimized the performance, stability, function and appearance of products, and developed LED interactive floor tile screen, LED shaped screen, LED rotary screen, LED spherical screen, LED flexible curved screen, etc. These LED special-shaped screens with different shapes give people a strong visual impact, gathering more popularity for commercial real estate and shaping urban landmarks. Do you know the difference between transparent LED screen and traditional LED screen?
On November 2, 2020, the Ministry of Industry and Information Technology of China and other five departments issued the Action Plan for the Integration and Development of Virtual Reality and Industrial Applications (2022-2026), proposing that by 2026, the overall scale of China's virtual reality industry (including related hardware, software, applications, etc.) will exceed 350 billion yuan, the sales volume of virtual reality terminals will exceed 25 million, 100 backbone enterprises with strong innovation ability and industrial influence will be cultivated, and 10 key enterprises with regional influence The cluster area leading the ecological development of virtual reality has built 10 industrial public service platforms.
The agency believes that the XR head display is the next generation immersive experience portal. At present, the global annual sales volume of the C-end has exceeded 10 million, and the industrial application will be the key breakthrough in the future. At present, XR+AI deep integration has been applied to smart manufacturing, energy, urban, education, office, agriculture and many other fields. Compared with the C-end, the B-end product has a higher unit price (several times higher than the consumption level), stronger industry barriers, and higher long-term certainty.
In addition to improving the appearance and performance, LED special-shaped screen is also equipped with many interactive technologies, AR/VR/XR, 5G, naked eye 3D technology and face recognition to make the urban landscape display more vivid. At the same time, LED special-shaped screen can also be combined with urban landmarks and lighting to make the lighting project more colorful. Moreover, LED display has become an important part of the lighting project with its wide coverage, high transmission rate, striking, strong visual impact, large area seamless splicing, waterproof and colorful pictures. Do you want to know the effect of 5G LED display?
Especially in places with dense traffic, this creative LED display brings a shocking visual impact to the audience. Moreover, it can not only achieve publicity effect, but also achieve diversified publicity methods. These diversified publicity effects meet the needs of advertisers for advertising, and also meet the needs of urban beautification. More importantly, it can solve the light pollution problem of traditional LED outdoor display screen, so it plays a very important role in the night tour economy.
Although creative LED special-shaped screen plays an important role in landscape display, people prefer the effect of special-shaped display. Although the price of the special-shaped screen is on the high side and its market demand is small, there is a reason why it is expensive. Compared with the conventional screen, the creative LED special-shaped screen is more of an added value. Smart achievements are far greater than the cost of materials, and it also needs to bear a certain risk cost, which is where the value of customized products lies. Not all product values depend on the price of the product itself, but the intangible value that the product itself brings to customers.
The traditional LED display is due to the serious homogenization deadlock. In order to seize more market resources, LED display enterprises have to resort to price war, but this is not a long-term solution. If LED display manufacturers want to develop in the long run, they must constantly carry out innovation and research and development, and LED special-shaped screen is the result of LED screen enterprises' research and development. Facts have proved that when various customized LED special-shaped screens appear in the landscape display projects of various cities, they are favored by people, and even become a punch in resort. Moreover, the reason why a sculpture or architecture of a city has become a landmark of a local city is that it has its unique personality and distinctive colors of the local city. If such landmark buildings are copied continuously, they will become stereotyped. If the products produced by LED display manufacturers are copied and pasted continuously, the products will lose competitiveness, which is the main reason why some LED display manufacturers always adhere to innovation and research and development.
As the carrier of information display and data visualization, the display screen plays an important role in the digital upgrading of various industries. Ouyang Zhongcan, an academician of the CAS Member, pointed out that China's display industry must strengthen the dominant position of enterprises in technological innovation, promote the integration and innovation of upstream, midstream, downstream, large, small and medium-sized enterprises in the industrial chain, and establish an independent, controllable, safe and controllable industrial chain as soon as possible. Sostron teaches you how to maintain the information security of your LED display.
In a word, as the lighting project is in full swing in various cities, LED displays are increasingly used in landscape display projects by virtue of large areas of seamless splicing, high brightness, wide coverage, high arrival rate, long viewing distance, unique and diverse modeling and other characteristics, coupled with interactive, 3D, AR/VR and face recognition technologies. Of course, LED display manufacturers should not only form their own unique style and characteristics, but also constantly improve their creative space, constantly tap new customer needs, speed up channel expansion, form their own differentiated routes, and find more business opportunities.
