In an increasingly advanced LED technology development, before only for indoor SMD LED display large quantities used in outdoor, gradually encroach line market share. As we all know, a few years ago in the outdoor LED display are all using in-line devices, and low-paste screen brightness, and can not adapt to the outdoor complex environment, SMD LED display can only be widely used in indoor, The device is an exclusive line of outdoor LED display in the world. Today, the development of technology to make surface-mount display is no longer confined indoors, outdoors rise and begin to get a more rapid development, and access to a wide range of applications, and in-line LED display in the world competing for outdoor display.
Outdoor SMD obvious advantages
Compared to the product line, with a wide viewing angle SMD outdoor light with a good, good mixing, high contrast edge. Outdoor full color paste only has a wide viewing angle of 110 degrees or more in the horizontal direction, vertical direction also has more than 110 degree wide viewing angle, so the suspension is in need of high-altitude outdoor display outdoor paste this have a broader perspective of full color in order show better advertising results.
Furthermore, compared to in-line LED, outdoor table posted better consistency. Inline red, green and blue oval LED three lighting at different angles of the consistency index is difficult to achieve, and outdoor table attached to be able to do at different angles of red, green, and blue brightness matching consistency height consistent, ensuring outdoor full color SMD LED display brightness at any angle consistent, to achieve better color realism.
In addition, full-color surface mount line is much smaller than the volume of light, so a small emitting area, a large black area, improve the contrast LED display. SMD three in one design of the structure, its built-in red, green, and blue chips, can be used as a pixel of the display. The line LED lights, its built-in single color chips, at least red, green, and blue lights of different colors each one bolted together to form a full-color display pixels. Therefore, color mixing display full color SMD LED display better than the oval line.
Moreover, outdoor full color display Free Glue stick, and the products more light, easy and efficient installation. Its aluminum alloy casing design is lightweight, easy to assemble and easy to deformation beautiful flat. Suitable for leasing companies, car display, mobile media use; post installation or wall installation more to alleviate the pressure on the bottle of steel structures.
Outdoor SMD display module circuit design enables light board and driver board combo, easy to automated production. Compared to in-line products, outdoor surface mount not only improve the reliability, improved productivity, more importantly, reduce costs. For outdoor surface mount advantage, the US card Lok Optical Co., Ltd., general manager of Hangzhou Jiang Zhongyong bluntly: Outdoor paste compared to line has two distinct advantages. First, the outdoor surface mount display and viewing better than the line; Second, outdoor surface mount angle, more suitable than the line spacing smaller LED display.
Admittedly, such as the US card Lok Jiang said, due to various reasons of policy guidance, market demand, require full-color LED display dot pitch smaller and smaller, and the traditional in-line LED display technology has clearly unable to meet the needs of the application environment. With LED packaging technology matures, lamp beads patch widely used in the field of LED, LED full color display surface mount technology became popular industry, the LED full color display applications pushed to a new height. Compared to traditional in-line full-color LED display, outdoor surface-mount display screen more gorgeous, more energy, more light box, a wider viewing angle, whether it is used in indoor or outdoor, to replace the traditional full-line LED color display has become a trend.
Outdoor SMD Difficulties
In recent years, outdoor surface-mount products can not be compared with its single lamp triple and dither mode, more and more instead of the traditional single-lamp products, become the main choice for outdoor LED display. However, you want to paste the product is applied to the outdoor LED display, it is not easy, not only for surface-mount products have a deep understanding of the need for more outdoor LED display has in-depth analysis.
Packaging Technology
Outdoor paste the name suggests is the application place outdoors, so the paste products to be tested rapidly changing outdoor environment. It also makes products for outdoor surface mount packaging process more difficult, whether it is material matching, thermal stress, the material and the substrate adhesion, which have more stringent requirements. How to do in case of changes in performance to maintain a good combination, this is a difficulty.
Glue craft
Traditional outdoor screen in the filling module colloid in the sun and rain and ultraviolet irradiation will gradually aging, would split off after the colloidal properties changed, so that the circuit boards and LED lose the protective layer, even after a long period Thermal expansion and contraction after reach waterproof effect, and the glue will go through the gap into the screen body, have a corrosive effect on the PCB board, affecting the entire screen life and stability. If you are using SMD outdoor triple potting process, then its light foot too short, too thin plastic irrigation, more serious consequences.
Waterproof
In addition, water and moisture has been a key parameter outdoor full color SMD SMD's. Although, with the development of LED chip and packaging technology, surface-mount brightness and protection class has been able to meet the needs of outdoor applications, but also need to continue to break. For outdoor surface mount, the two major difficulties is no longer waterproof outdoor SMD LED display promotion greatest difficulty. However, the price that is the king of the market, we want to get people Wumart also need cheap.
Costs
For a long time, the high cost of surface-mount product for a long time one of the factors can not fully replace the lamp line. DIP lamp with its low price accounted for half outdoor screen, compared with the conventional line lights, the price is clearly higher surface-mount products. SMD product that you want widely used in outdoor display, the price must be addressed. In order to reduce the price, only in technology continue to study, through technology to reduce costs is an effective solution.
Outdoor SMD LED display development trend and fashion
With the development of outdoor LED displays, surface-mount packages starting from indoor to outdoor, outdoor SMD LED display more and more popular, expanding market share. In this regard, the US card Lok Jiang said outdoor SMD demand will be further expanded, and will occupy the mainstream market, the gradual encroachment line market share, but it will not completely replace the line products, because in certain situations, or more suitable for use in-line products. From a distance, such as high-rise atop the LED display, because of distance, angle factors is small, but more power, in this case does not require surface-mount. Of course, outdoor surface-mount products in sealing, high temperature resistance, UV resistance and other aspects need to be further strengthened. Obviously, there are many companies in these areas were not doing well. With the progress of LED display technology, LED display packaging industry concentration will be higher and higher, so-called survival of the fittest, to surviving the fierce competition in the business must have its features. With a time of invasion reshuffle tide, a future without their own unique advantages of the enterprises is bound to be eliminated.
Surface-mount packages for outdoor is the trend, is an irresistible trend, production will continue to increase. Deputy General Manager of Optoelectronics Co. RGB Devices Division Ouyang wavelet Foshan, China also expressed their views: the country star power is very optimistic about the outdoor surface-mount products, and is currently the only manufacturer of large-scale production, performance reached the international leading manufacturers level. Currently, the outdoor surface mount line to gradually replace the lamp or lamps need to further improve the brightness, cost, air tightness and other issues, along with the rapid increase of the chip height and expanding the production capacity, the problem will be gradually resolved.
SMD tend to develop more high-definition small pitch surface mount complement each other
In addition, with a small pitch to the continuous development of technology, people LED display will be more high-definition requirements, outdoor surface-mount no exception. That is, the outdoor table will stick to the HD future direction. Therefore, outdoor SMD LED display that you want tend HD, you need to do a smaller pitch, and a small pitch LED display that you want in the outdoor market foothold, table a high-quality choice Mounted LED devices are also its development . Thus available, posted a small pitch and table combination, will make the outdoor SMD LED display tend to be more high-definition, to meet the needs of the market, which occupied the outdoor display market.
In recent years, the market demand for outdoor SMD LED display products increases, outdoor SMD LED display with its dot pitch is small, high-definition display and other advantages, gradually gained customers. It is such a focus on the outdoor surface mount areas of business, in 2015 Guangzhou LED Show, shows a variety of outdoor SMD LED display, which is within the current global market P3.9 range of outdoor SMD products which the minimum spacing paragraph. In order to meet the high-definition outdoor display applications demand, Deming outdoor light will continue to paste smaller spacing direction, developed a P3 and a smaller dot pitch of outdoor surface-mount products.
As a Chinese manufacturer of LED display strength, the first open global outdoor small pitch LED display blue ocean market. As outdoor high-definition LED display innovation leader who has been committed to film the development and application of outdoor LED display, has been at the forefront of energy-efficient LED outdoor high definition display applications, its self-developed P5 outdoor SMD LED display becomes the moment The most popular outdoor small pitch products. Future, outdoor full color paste will gradually replace the in-line product, real outdoor Indoor screen development trend. Meanwhile, the outdoor SMD full color but also with the combination of high-density products, to the definition of high-density direction.
For better viewing, people on the screen display requirements from simple to vivid full-color, restore the color of truth, but also on a smaller screen to achieve as comfortable as television, clear image. Therefore, high-density fine pitch LED display to represent the high-definition display will be the future trend of development. The outdoor SMD full color screen display, beautiful, perspective, maintenance and other aspects obvious advantages compared to in-line, and more to meet the requirements for outdoor use.
