Advantages of SMD LED over DIP Display

With the constant progress of LED display technology and people’s requirement for viewing is increasing day by day, SMD packaging products began applicant outdoor, SMD LED display even more popular. In the application of the market is increasing obviously, also let many enterprises go to the road of outdoor SMD. However, the trend once aroused people’s hot because of a lot of quality events. Whether SMD packaging product can replace DIP for outdoor LED display, what are the technical problems need to solve?
In a few years ago, almost all the outdoor LED display using direct plug-in oval red, green, and blue LED device, and in recent years, the pixel pitch spacing for 8 mm to 16 mm outdoor full-color LED display is gradually rising, which get a wide range of applications. Recently, M-shine P5, P6 SMD LED displays are sought after by the market, become popular applications to the gym.

Technical advantages of outdoor SMD compared with DIP:

Wide-angle of view

Outdoor SMD LED display not only in horizontal direction has a wide perspective of over 110 degrees, in the vertical direction, also has more than 110 – degree wide Angle of view, so have a distinct advantage in some places, such as high building screen, hanging in the sky, outdoor LED display requires a broader perspective to show better advertising effectiveness and dance with the floor.

With good light

Red, green, and blue oval LED three brightness matching consistency in different angles is a highly difficult indicators, and full-color SMD design structure for the triad structure, three red, green, and blue-chip in the bowl of a stent, in red, green, blue three kinds of different Angle 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.

Mix light good

Due to the design structure for 3 in 1, three chip 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 better than straight elliptical LED screen, especially suitable for a closer look.

High contrast

Due to the design structure of 3 in 1, full-color SMD size is small, so the light-emitting area is small, and the black area is large, thus to improve the contrast of the LED display.

Automated production

SMD LED can be able to use an automatic SMT machine, high production efficiency. Outdoor SMD LED display module circuit design can achieve the light board and drive board dual function, reduce the cost and improve the reliability, enhanced production efficiency. In addition, automated SMT production also can improve the vertical accuracy on the circuit board, overcome the upright type ellipse LEDs on the circuit board vertical accuracy problem, thus ensuring a better optical effect.

Slim

Using aluminum alloy material, cabinet structural design is very light, and nice appearance, easily assembled and smooth. Suitable for rental companies, car screen, mobile media use Pillar or wall installation ease the pressure on the screen of the steel structure.

No need potting

In traditional LED outdoor screen module filling colloid in weathered and will gradually aging under the irradiation of ultraviolet light, colloid properties change and will be split off, the circuit board and LED lost protective layer, even after a long time cannot reach the waterproof effect after the heat from the cold, and glue can slip into the screen body, corroding the PCB, and affecting the service life of the whole screen and stability; If outdoor SMD 3 in 1 pot glue, will have even more serious consequences because its lightfoot is too short, and glue is too thin.
Previously, the brightness of the SMD LED is low, and the functions such as waterproof, moisture-proof, prevent ultraviolet could not reach the requirements of the outdoor environment, so the outdoor full-color LED display screen is usually using DIP type. SMD full-color LED display can only be used indoors. Recently, 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, so rapid application was obtained.

Key Advantages of LED Sign Board

A sign board is a board that displays a business or product name, logo, or any advertisement news. It gives us short details about a company or a commodity. When we think about it now all over there is sign board. Some showcase a celebrity, some showcase special offers and some showcase a benefit to the client. For most businesses, building company signage or sign board was a basic necessity. It was a vital method to gain respect from each business ‘ prospective customers. With the passing of time and the advancement of technology, the conventional  Led sign board   has gone from being easy and inexpensive to becoming an interactive and larger marketing tool. Nevertheless, both the traditional and modern types of signage are still widely used nowadays in all parts of the globe. Basic advantages of Signboards are: It helps one’s target customers to locate the store or business place Provides information without the need of searching for it Drives traffic to one’s ...
