With the wide application of LED display, higher requirements are put forward for LED display – small pitch LED screen. High-density and small-pitch LED display is an important emerging market in the industry, and it is also one of the markets with high product profit margins. Small-pitch LEDs can be used indoors, and the resolution has been greatly improved.
Outdoor display and indoor display because of their different application environment, the requirements for the display are quite different, of which the resolution, that is, the pixel spacing is an important factor. For LED displays, each self-illuminating package device, the lamp bead, is a pixel, so the distance between the two lamp beads determines the resolution of the LED display in a unit area. In general, the industry will use the distance between the lamp beads to indicate the model of the product, such as P10 products show that the distance between the two lamp beads in the screen body is 10mm (mm). Due to the large outdoor space, the viewing distance of the audience is generally farther, and the human eye has a certain discernment limit, so when viewing at a distance, even if the point spacing of the LED display is far, it can meet the requirements. Due to the limited indoor space, the viewing distance is generally smaller than outdoor, so the display with a smaller point spacing is needed to meet the user’s requirements for resolution, otherwise it will affect the viewing effect.
According to the prediction of relevant agencies, in the next few years, the global LED display market demand will still maintain rapid growth, the average annual growth rate will exceed 20%, it is expected that by 2020, the global LED display market size will reach 30 billion US dollars, China will be the most important manufacturing base. As an LED display company, only by having a “product that can be handed”, or “a product that reminds people of you can remember” can it really be based on the market and let others look at you. After the development of 2015, the application prospects of LED displays in some subdivisions began to appear, so in 2016, what are the LED display products with application prospects? Let’s take a look.
LED glass curtain wall screen
LED media curtain wall is based on LED material technology, multimedia technology and the artistic design creative perspective of the exterior wall image, plus design elements such as sound and image, forming a new public art form. In recent years, with the improvement of the world economy, the development of cities, and the intensification of competition in the advertising industry, the media curtain wall art form in modern cities has become more and more popular with citizens.
With the improvement of computer digital multimedia technology and design software technology, the continuous innovation of media curtain wall technology and the creative combination of art forms, the appearance of the building ushers in the miracle of architectural science and art almost every day. In general, image quality and operating parameters rely on computer technology and screen control system functions, rely on modern building skin screens complex computer control systems and screen lighting components, operating media curtain wall surface interactive forms, advertising, lighting, audio-visual, built environment, television or video programs, such large-scale projects are usually designed by architects, engineers, mathematicians, programmers and artists.
3D LED display
With the application of LED display more and more extensive, people’s requirements are getting higher and higher, now people can no longer meet the two-dimensional plane display, but also hope to truly restore the three-dimensional information of the real world, so the application of 3D display technology on the LED display has become a hot spot and direction of research in recent years. At this year’s Guangzhou International LED Exhibition, we also saw that many LED display manufacturers are sparing no effort in making corresponding technological innovations for 3D LED displays, and have shown their magic in the research and development of 3DLED displays.
In order to make up for some technical limitations of naked-eye 3D technology, some LED display manufacturers have gradually turned to active 3D technology in the continuous research and development process. Active 3D technology can also be called shutter 3D technology, is achieved by greatly improving the refresh rate of the picture, which divides the image into two groups according to the frame, forming the left and right corresponding screens, continuously interlacing to produce images, and then seeing the 3D image through the synchronous on/off operation of the lenses of the shutter glasses. Unlike polarized 3D, he can restore the original resolution of the picture, and can easily enjoy the Full HD 3D image, breaking through the limitations of the original naked-eye D “multi-view” position.
Small pitch LED TV
With the advent of small-pitch LED displays, small-size products that can be viewed up close to the market for indoor applications have emerged.
Small pitch LED TV because of the brightness adjustable, high efficiency and energy saving, long use time, low maintenance costs, high refresh rate, screen no flicker, wide viewing angle, ultra-quiet, ultra-light and thin, no burns, support for 3D display, multi-window display arbitrary zoom and other advantages, favored by many manufacturers.
Nowadays small-pitch LED TVs have the conditions to enter the room. Through the detachable design, the large-screen TV is split into several 56-inch units, and the problem of difficult entry is solved. The second is the price of diving, compared to large-size LCD TVs, small-pitch LEDs are at least 40% cheaper. In the future, it is expected to be promoted from the commercial market to the high-end civilian market.
Wind/solar LED display
Wind and solar complementary or solar power LED display system is a new type of green high-tech products, absorbing natural wind and solar energy for LED display equipment power supply, no need for mains power distribution, not limited by installation area, no need to lay power supply cables, on-site construction, installation and post-maintenance are very convenient, the comprehensive benefits are good. Wind energy, light energy as an environmentally friendly, pollution-free clean energy, reasonable cost, easy installation and maintenance, will gradually replace the traditional power supply methods. It is generally used in highways, national highways, urban roads, road networks of main highways, urban highways, streets, airports, wharves, stations and other transportation places.
Solar LED display and wind and solar complementary LED display due to small power consumption, you can choose a cable with a small wire diameter, the initial total investment value of the required power supply part is lower than the original cost, reducing the investment cost. The total initial investment in the power supply part required for the solar-powered LED display is 30% lower than the original cost of laying cables, which greatly reduces the investment cost.
LED advertising machine
Relying on the inherent advantages of LED display, compared with the traditional LCD advertising machine, LED advertising machine has many advantages in the outdoor environment. In terms of display effect, LED screen brightness reaches 5000cd/m2, and the propagation effect in outdoor environment is much better than that of LCD screen. In addition, the LED display is also better than the LCD screen in terms of viewing angle, color reproduction ability, and dynamic screen elimination of smearing phenomenon.
Nowadays, advertisers are increasingly favored by new marketing methods such as two-dimensional codes, LBS, and even the latest NFC payment methods, and LED displays are the best advertising carriers. Interactive technology can also be used to enhance the interaction between the screen brushing machine as an advertising medium and the advertising audience, such as customizing the touch screen and realizing the cloud technology broadcast control management.
LED pole display
Street lamp pole screen has the characteristics of synchronous reception, synchronous playback, used on the highway, no matter how far the car travels, there is always a high-definition street lamp screen to play the content of the accompaniment. The light pole screen not only has unique advantages in road guidance, road condition broadcasting, information release, advertising promotion, etc., but also has a considerable effect on alleviating the fatigue of car drivers on the highway.
LED light pole screen with its multi-point delivery characteristics, in a certain area to form a scale effect. For example, in a certain section of all the light poles are placed on the LED light pole screen, coupled with the network simulcast technology, dozens of hundreds or even more light pole screens at the same time loop the same advertisement, so that the visual impact on consumers or invisible consumers is very strong, but also can deepen their memory of the advertisement, so such advertising effect is no less than outdoor large-screen advertising.
In the future, with the continuous development of the economy, the demand for external display publicity is increasing, and more requirements will be put forward for the LED display industry, with higher resolution and more realistic colors. The LED display industry will certainly go further, and China’s electronic display industry will continue to move towards the forefront of the world.
