Recently, outdoor LED display industry giants of * * * m&a events we will let the eyes once again focused on the outdoor LED display field. Outdoor LED display in the advertisement demand development at the same time we analyze the cause of it mainly has the advantages of the five aspects but in LED display technology development at the same time, we recognize the outdoor LED display because of its characteristics is also facing challenges.
The advantage of the outdoor LED display is analyzed
Outdoor LED display in the past two years, the outdoor advertising market demand, LED outdoor display screen popular, mainly LED display has the following advantages:
1. The strong visual impact, large size, verbal persuasion and the unity of sound painting LED advertising can omni-directional actuation audience senses, effectively convey information to guide consumption. In the face of overwhelming advertising, the audience limitless memory space limitation and the spread of information, make the attention gradually become a kind of scarce resource, so the attention economy has become a test of advertising effect maximum size.
2. Coverage: outdoor LED display is generally installed in the high-grade commercial and traffic density large
transport hub area. Through the communication with the consumer high frequency, an urge to motivate consumers to buy.
3. Release time long: outdoor LED advertising can uninterrupted broadcast 24 hours a day, its information communicate around the clock. This feature makes it easier for the audience to see, can better guide potential customers to the crowd, the merchants with less cost to achieve better publicity.4. The audience off rate is low: outdoor LED advertising can live through technology, authentic, timely broadcast to more audiences. Including project, column, variety, animation, radio, TV, etc., rich in content, avoid the advertisement audience consciously take the initiative to avoid touch barrier. Research shows that the outdoor LED display advertising aversion rate is far lower than the rate of television advertising aversion.
5. Upgrade the city: government agencies use of LED advertising some government affairs information and announcements of the city, and can beautify the city image, city level and taste. LED display is now widely used in sports venues, conference center, advertising, transportation, etc., it reflects the economic, cultural and social life of a city.
LED display is worth looking forward to in the future
LED advertising from the outdoor advertising media company, the main reason lies in the products of LED display itself advantages. LED display as the fourth generation of new media, environmental protection and energy saving, high resolution imaging, exquisite natural color, can show video and text and broad perspective and other modern high-tech, fully meet the technical requirements of modern advertising media as well as the urban population of ornamental requirements, is the perfect combination of high-tech and traditional media. In addition, the LED display technology constantly breakthroughs for outdoor advertisement causes all sorts of new changes. Such as outdoor LED display high pixels from the product to display the performance, the intelligent control of the display brightness effectively removed the screen is too bright and light pollution caused by the door appearance on the LED display screen is more thin than straight insert, the picture is more exquisite.
Outdoor LED display advertising compared with other media advertising has more distinctive features and advantages. Increasingly advanced LED technology provides the opportunity for outdoor advertising into LED era. In the future, intelligent LED display will lead the audience to intuitive interaction, when viewed from the far closer to real media and audience.
The challenges of the outdoor LED display screen
But compared with the indoor LED display, outdoor environment more complex, to ensure that the LED display screen in the outdoor applications and there are many place is worth considering.
Indicators: 1, the resolution to meet all kinds of long distance or apparent effect of high ambient light conditions. Traditional liquid crystal appeared only 1024 x 768 resolution, and according to the actual test data, the resolution of the outdoor application to show equipment needs to at least 1920 x 1200, can under the influence of the sun appeared normal, for LED advertising machine, "resolution" will not become too big difficult problem of its application popularization.
2, waterproof and dustproof: to all outdoor use, waterproof and dustproof is the first face, show equipment casing protection grade must be waterproof, waterproof level is IPX5 commonly, can run normally in the heavy rain; Dust is falling commodity efficiency and accelerate product aging, the important factors that appeared outdoor equipment should be specially designed dust and dust filtering commodity structure, dust-proof grade reaches IP65.
3, intelligent constant temperature: outdoor advertising machine at run time from solar radiation, air convection, the internal electronic components of three principal aspects, such as fever heat, according to the regional difference in temperature and equipment placed different LCD confidential with temperature control scheme is determined. Have a plenty of KongDiaoXing type radiator, some compulsory air-cooled heat dissipation. But no matter what the cooling scheme, goods generally meet the temperature: - 30 ℃ - 55 ℃, humidity: 10%, 90% operation requirements.
4, riot security: outdoor equipment commonly used in outdoor public places, is open to public safety and the safety of the device itself appeared to thinking on the problems of general appeared outdoor equipment can use special tempered laminated glass, even if the glass is broken, also can produce similar spider mesh finely crack, pieces of its strong adhesion on the middle tier, can avoid the glass drop caused personal injury or property loss. In addition, the problem of guard against theft, should avoid screw exposed, and combining the anti-theft lock functions and the structure of the solid support, solve the security problem.
5, lightning protection, to complete the all-weather outdoor play performance, outdoor equipment must have the reliable lightning protection electric control design, the thunderstorm day for equipment supply security guarantees.
6, prevent reflection: outdoor environment show visible interface, the reflection is also a thinking to important aspect, it is necessary to adopt the special coating process of glass, in order to improve the image visual point of view and resolution, reduce the reflective screen.
7, prevent electromagnetic disturb: outdoor environment not controllable, preventing electromagnetic disturb function appeared to outdoor equipment become very important, we can't go to outdoor environment, but we can internal shielding measures should be adopted for electrical parts of equipment, which effectively prevent internal components, cables for signal, but also to prevent external electromagnetic disturb of LED products.
