Surface mount is the development trend of outdoor display
With the people on the led display technology continues to focus on the requirements of the ornamental also continue to improve, on this basis, outdoor surface paste packaging products gradually into the people's vision, as led electronic display products leader, In the development trend of the industry, occupy a very important position, and then for some time, its quality level has also aroused widespread concern of users, while the market on the surface paste products and in-line products also put forward different views.
Relative to the surface paste packaging products, in-line module has been widely used many years ago, the technology has also been very mature, nearly two years of outdoor full-color table was gradually into the people's vision, because of its effect On the more because of the in-line module has been widely used and attention.
So what is the advantage of outdoor led display led display?
A good light distribution. Red, green, blue oval led in different angles three kinds of brightness matching consistency is a very difficult index, and full color SMD because the design structure for the triple structure, red, green, blue three chips all in the A stall cups, so in different angles red, green, blue three kinds of brightness consistent consistency of the same, so that outdoor full color stickers led full color display in any angle brightness match consistent good, To achieve a better color realistic effect.
Second, wide perspective Outdoor surface stickers full color screen not only in the horizontal direction with more than 110 degrees wide viewing angle, in the vertical direction also has a wide viewing angle of 110 degrees, which in some applications are particularly advantageous, such as building screen, hanging in the high-altitude outdoor led display Need a wider perspective to show better advertising results.
Third, high contrast. As a result of the three-in-one design structure, full-color SMD size is small, so the light area is small, black area, improve the contrast led display.
Four, mixed light good. As the design structure for the three-in-one, three chips from the very close, in the same bracket bowl mixed with light, rather than three separate oval led, so red, green, blue blending better than straight oval led Screen, especially suitable for close viewing.
In addition, the surface mount led to the use of automatic placement machine for automated patch, high production efficiency and lighter. Automated SMD production can also improve the vertical accuracy of the SMD on the circuit board, to overcome the vertical oval led on the circuit board vertical accuracy problems, so as to ensure better optical results.
Previously, due to the low brightness of the surface display led display, and waterproof, moisture-proof, anti-ultraviolet function can not meet the requirements of outdoor harsh environment, so the outdoor full color display is in-line led device world. Full color stickers led display can only be used in a large number of indoor. With the led chip technology and led packaging technology advances, SMD brightness and protection level has been able to meet the needs of outdoor applications, access to a more rapid application.
In the past period of time, because of its moisture-proof. Water and brightness is not high and other factors, more used in indoor use, the past two years, the surface is technically developed, there is no such problems The.
Even so, but the surface of the application in the outdoor area is still far less than the in-line module, we have to face up to this reason.
First, compared with the traditional in-line products, the price of surface mount devices is clearly higher. With the price of this substantive threshold, outdoor display led display a wide range of applications yet to be.
Followed by the harsh outdoor conditions lead to surface mount device packaging technology and its difficulties.
With the tire display manufacturers tireless efforts in the development of R & D technology on the basis of continuous development, the surface of the product will be the future development of outdoor led display trends and trends.
