The encapsulation of LEDs is the most important feature of LED Smd Screen technology. LED encapsulation can increase the luminous efficiency and heat dissipation environment of an LED display, allowing the display to last longer in operation. DIP and SMD LED encapsulation are the most widely used types of LED encapsulation. At the moment, COB packaging is being employed in LED Smd Screen technology. The objective of this work is not to introduce or compare different COB packaging systems, but rather to discuss them.
LEDs in DIP (Dual In-line Package) packages are based on potting. Following the injection of liquid epoxy resin into the LED moulding cavity, insertion of the pressure-welded LED bracket, curing the epoxy resin in an oven, and finally removal and shaping of the LED from the cavity are all steps included in the potting method. Individual bundles are available in three different colour schemes (Red, Green, and Blue).
In SMD (Surface Placed Devices) LEDs, the LEDs are mounted directly to the circuit board’s surface and are suitable for SMT processing and reflow soldering procedures. SMD 3IN1 LED refers to a surface-mount lamp that contains three different colours of RGB LED chips packaged in the same gel at regular intervals, each of which is of a different colour.
There are six significant differences between DIP LED displays and SMD LED displays
1. The use of the software
The use of DIP LEDs is restricted to the outdoors, but the usage of SMD LEDs is permitted both indoors and outside. Due to the limitations of DIP LED production procedures, we are unable to manufacture DIP LED screens with very small pixel pitches. P20, P16, P10, and P8 are the most common pin configurations for DIP LED displays. It is possible to lower the pixel pitch of an SMD LED display. Currently, SMD LED screens with a pixel pitch of 1mm are possible.
2. the degree of radiance
DIP LED screens have a higher brightness than SMD LED displays. Each of the three R, G, and B bulbs in a DIP LED is connected to its own circuit. It is quite easy for each lamp to reach the maximum brightness current available.
3. The Perception of Color
When it comes to colour performance, SMD LEDs trump DIP LEDs hands down. The space between the RGB colours is closer in SMD LED displays. It is possible to treat the surface of an SMD LED with diffuse reflection, which results in the absence of granular effects and excellent colour consistency. SMD LED light separation is less difficult than DIP LED Smd Screen light separation, and the colour saturation of SMD LEDs is higher than that of DIP LEDs. It is more constant in colour since SMD LEDs produce light from the full surface of the device; therefore, they are more energy efficient. The colour rendering of SMD LED displays has improved. The overall flatness of SMD LEDs may be controlled with relative ease.
4. The Direction of Viewing
It is more difficult to see through an SMD LED than it is through a DIP LED. Because DIP LEDs have three separate colours, it is impossible to fine-tune the viewing angle of the LEDs accurately. SMD LEDs are tricolour LEDs that are packaged in a single package. It is simple to change the viewing angle of the monitor.
LEDs with a viewing angle of 100 degrees or less are commonly used; LEDs with a viewing angle of 120 to 160 degrees or more are commonly used. Security is the fifth point.
DIP LEDs have a higher level of protection than SMD LEDs
As a result of the advancements in DIP LED manufacturing technology, it has become more simpler to implement protection measures like as water and shock resistance, among other things. However, when it comes to protection, SMD LEDs are performing better than ever before.
Maintenance Fees are the sixth item on the list.
DIP LEDs require less care than SMD LEDs, and they last longer
Each colour of a DIP LED is unique from the others. Changing a single colour LED mustangled is a straightforward and inexpensive process. In this case, however, the entire SMD LED must be replaced because it has failed.
