Both segmented displays and LED matrixes are designed to display a specific image. Segmented displays provide us with information that consists of numbers, letters or special characters. The control system generates two-state signals, allowing you to enter the specific data you want them to display. Also in this way it is possible to read the measurement data. Segment displays are ubiquitous in our everyday life. They can be found in calculators, household appliances, watches, as well as on the operating panels of machines and measuring devices. They are used in street advertisements and boards with scoring or countdown time in quiz shows. Segmented displays differ in the number of characters. We can distinguish single displays, as well as two-, four- and eight-character displays. Seven- and eight-segment displays are most often selected. In addition, we have a wide selection of LED matrixes with a diode resolution ranging from 1x8 to 64x32.

Segmented displays
Segmented displays use LED technology. The LEDs are conductive, which makes it possible to illuminate the segments. The most popular solutions include 8-segment displays, consisting of four vertical or inclined lines outwards and three horizontal lines, which are arranged in the shape of the digit 8. The last, eighth segment has the shape of a dot. A single segment lights up when it receives a voltage polarizing diodes. The brightness of the light is determined by the amount of current flowing through the diode. As far as the light colour of the segment is concerned, it depends on the voltage on the diode. Red appears at a voltage of approx. 2.0-2.2 V, while blue appears at approx. 3.6 V.
The segmented display is controlled by logical systems. Microcontrollers or, for example, CD4511 and BCD decoder are used. The system supplies 5.0 V, it also has four inputs, which are marked with letters from A to D, with bits 1, 2, 4 and 4 weights assigned respectively. The controllers are equipped with seven logical outputs and each is assigned to another segment. It is important to know that when selecting resistors, it is necessary to set the light intensity of the segments accordingly, adjusting it to the needs of a particular project.
LED matrixes
In everyday life we often come across matrixes that are made of RGB LEDs. This is a very interesting solution, which is used in the advertising industry among others. These are two-dimensional arrays, on which graphic symbols and various types of signs are displayed, as well as any other information and images that are informative and advertising. LED matrixes are used not only in the production of advertisements, but also, among others, information boards for passengers at railway stations and public transport. LED matrixes can also be controlled from the level of Raspberry PI and Arduino boards. They are characterized by a built-in controller, which allows to operate the matrix using only one microcontroller pin. In our offer you will find a wide range of LED matrixes, which differ in column and row sizes. You can choose between 1x8 and 64x32. These are elements that work very well in many electronic projects. You can use them to enrich the look of your operator panel's interface or you can build a board on your own, which will display impressive animations.
Check out the full range of our segmented displays and LED matrixes. We have a wide range of displays, consisting of one and several matrixes. Moreover, we recommend LED matrixes which are perfect for technologically advanced projects and allow you to create tables for displaying graphics and animations. They are also great for advertisers, as well as for those who just want to try their hand at this industry. Check what we got for you!
