In this type of construction, LEDs are mounted to the boards using the through-hole method. This method is based on the classic combination of elements. the board, and then are connected with solder on its back side. This production method also allows the basic color model to be extended by another one, so that greater contrast can be achieved. The maximum number of LEDs can be up to six. However, due to costs and not necessary, such a solution is used very rarely. Through-hole screens are most often used outdoors.
The tight and compact housing allows for perfect protection against weather conditions harmful to electronics. The second most popular type of screens are those with SMD displays . As the name suggests, they are based on Surface Mount Devices. This image manipulation service means that the feet of the elements do not go to the other side of the board, but are mounted on its surface. In this type of display, each LED emitter forms an element in the form of a small chip. SMD screens are mainly used inside buildings, not only because they are more susceptible to moisture and temperature, but also because of lower brightness than the first type. The SMD construction allows for a brightness of 2000 candelas per square meter.
Another important factor that determines the capabilities of LED screens is pixel pitch, also called pixel pitch . A specific pitch of three or more pixels is called a raster . Pixel pitch is the distance between two pixels of the same color. However, in the case of SMD displays, measured from the center of one emitter to the center of the other. In addition, many manufacturers also construct devices with the virtual pixel pitch parameter . These screens compress the graphics information from the signal source and then send a split signal between the two available pixels. This allows you to significantly increase the possibilities and quality of the image.
