As the brightness of LED chip and LED packaging technology, outdoor full-color table posted the price of the LED into the full-color LED display
, the gap has narrowed considerably.
Door appearance stick LED full color because of the wide Angle of view, have good light distribution and mixing light, high contrast and the advantage of easy to automated production, its market share rising steadily, even is expected to become the mainstream direction of the development of outdoor video display system in the future.
1, wide perspective.
Door appearance to stick full color not only has over 110 degrees in the horizontal direction of wide Angle of view, in the vertical direction also has more than 110 - degree wide Angle of view, this particular have an advantage in some application places, such as LouYuBing, hanging in the sky of the outdoor LED display requires a broader perspective to show better advertising effect.
2, good light distribution.
Red, green, and blue oval LED brightness in three different perspectives on the matching of consistency is a highly difficult index, and full color SMD because design structure for the triad structure, three red, green, and blue chip in the bowl of a stent, in different point of view of red, green, blue three kinds of brightness matching consistency highly consistent, so as to make the outdoor full-color table stick piece to the brightness of the LED display in any Angle consistency is very good, get better vivid effect.
3, good light.
Due to design structure for the triad, three chip distance is very close, in the same bracket cup bowl mix light, rather than three separate oval LED, so the red, green, and blue mix light effect is good in upright elliptical LED screen, especially suitable for a closer look.
4, high contrast.
Due to the design structure of the triad, full-color SMD size is small, so the light emitting area is small, the black area area is large, to improve the contrast of LED display.
5, automatic production.
Table stick LED to be able to use automatic automatic SMT placement machine, high production efficiency.
LED door appearance on display module circuit design can achieve the light board and drive board dual function, reduce the cost and improve the reliability, enhanced the production efficiency.
In addition, automated SMT production also can improve the vertical accuracy of SMD on the circuit board, overcome the upright type ellipse leds on the circuit board vertical accuracy problem, thus ensuring better optical effect.
6, the body weight light.
Using aluminum alloy material box structural design is very light;
And nice out of shape not easily assembled convenient and smooth.
Suitable for the leasing company, LED rental screen, mobile media use;
Pillar or wall installation more ease the pressure on the screen of the steel structure.
7, no glue.
Traditional outdoor screen module filling colloid in weathered and gradually under the irradiation of ultraviolet ageing, colloid properties change after will be split off, lost protective layer makes the circuit boards and the LED, even after a long time to reach the waterproof effect after the heat from the cold, and glue will slip into the screen body, have a corrosion effect on PCB, affecting the service life of the whole screen and stability;
If a table is put outdoor triad glue process, because of its light foot too short, glue is too thin, even more serious consequences.
Previously, due to the table to stick the LED brightness is low, and waterproof, moistureproof, prevent the ultraviolet ray function could not reach the requirements of the outdoor environment, so the outdoor full-color LED display screen is upright type parts of the world.
Full color table stick LED display can only be used indoors.
With the progress of the LED chip technology and LED packaging technology, the brightness of the SMD and protection grade has been able to meet the needs of outdoor applications, rapid application were obtained.
LED display from monochrome to wide span varieties with full-color, adapt to a wide range of application provides the basis for its, and because of its high brightness, high reliability, strong ability to resist the ambient light, made on a number of outdoor LED display has an irreplaceable position and special applications.
LED door appearance screen for nearly two years to develop new varieties, the variety in color reproduction, color consistency, evenness, Angle of view, the picture has many aspects, such as the overall effect into light cannot go beyond the characteristics and advantages, it also makes the door appearance to stick a LED display advantageous guarantee of future trends.
