When manufacturing modules for LED screens, DIP or SMD LED are usually used. The fundamental difference between these two technologies is in the options for mounting LED on the board. DIP (Dual In-line Package) or DIL (Dual In-Line) technology implies a mounting method through through holes made in the board. This installation method is also called PHT (Plating Through Holes). SMD (Surface Mounted Device) technology involves placing LED and subsequent soldering on the surface of the board.

What is an LED Screen?

In the production of LED screens, both types of LED are used. In the production of monochrome screens, DIP LED are mainly used due to their low cost. DIP LED are also used in the production of full-fledged screens, but since DIP LED are single-color, to form a full-fledged color pixel of the screen it is necessary to use three LED: red, green, and blue. DIP technology is quite old, one might say that this is where it all began.

Who SMD Screen works

SMD LED is a new technology for producing LED. An SMD LED, as a rule, is already a separate pixel and is widely used in the production of full-color LED screens. SMD LED can display the entire spectrum of colors. But, in fact, an SMD LED also consists of red, green and blue LED, which is encapsulated in one package.

The fundamental difference between SMD LED and DIP is that the pixels of a screen based on SMD LED's can be very small in size, thanks to which manufacturers have the opportunity to produce ultra-high resolution LED screens. While DIP LED have a bulb of a certain size, a pixel consisting of three LED in any case has a size limitation, which does not allow creating screens with a pixel pitch of less than 8 mm.

SMD stands for Surface Mount Device. These are electronic components that are surface mounted directly onto the PCB, rather than by soldering a metal pin to the underside of the PCB as in the past. LED display technology uses the SMD concept a little differently. An SMD Screen is an LED display in which red, green and blue diodes are encapsulated in a small plastic housing that is mounted on the display circuit boards. When diodes are encapsulated in this way, they take up much less space, allowing for displays with shorter diode spacing and higher resolution.

SMD configuration

SMD configuration. This is the latest development that has significantly influenced the design of the LED screen. Its distinctive feature is that three LED of different colors are combined into one housing; sometimes they are designated RGB (3 in 1). SMD technology provides higher quality and clearer color reproduction. They are usually used for LED screens with a small pixel pitch indoors - concerts and sports halls, television studios, train stations and airports. SMD configuration pixels, as a rule, have lower brightness, it is approximately 1200-3000 dc/m2, in contrast to the brightness of DIP configuration pixels (6000-10000 dc/m2), but this is enough for indoor use, otherwise viewers will be blinded. They have lower power consumption, they are thinner and therefore lighter, they have good color stability, a large viewing angle, and a rich color palette. Recently, this technology has spread to LED screens for outdoor use.

The viewing angle is the angle within which the viewer observes the brightness of the image from 50% to 100%. The maximum brightness value will be if you look at the screen plane perpendicularly. For DIP configuration screens, the viewing angle is 120 degrees horizontally and 60 degrees vertically, for SMD configuration it is 120 degrees horizontally and 120 degrees vertically.

LED SCREEN - WHAT IS IT?

This is the name of a device for broadcasting video images, the picture on which is formed from numerous small dots - pixels. To download video content, the screen is connected to the computer using wires or wireless connections.

Electronic LED devices are available in different types:

·         street – large, with a wide viewing area;

·         for indoors – compact, with highly detailed images;

·         media facades – large, installed on buildings;

·         mobile – portable, resembling a computer monitor.
