What is a 7-Segment LED Display?
Have you ever wondered what those simple yet captivating digital displays commonly used in calculators, alarm clocks, and other electronic devices are called? Well, they are called 7-segment LED displays. These displays consist of seven individual LEDs (Light Emitting Diodes) arranged in a specific pattern to form numerals and some basic symbols.
A 7-segment LED display is a widely used form of digital display that can be found in a myriad of everyday devices. Each segment of the display is known as a segment because it represents one part of a numeral or symbol. These segments are arranged in the shape of an “8” and are used to display the digits 0 to 9 and a few additional symbols by turning ON or OFF specific segments.
The seven segments in the display are usually labeled “a” through “g,” with each segment corresponding to a specific part of the number or symbol it represents. By selectively activating these segments, different numbers and symbols can be displayed. To illustrate, let’s take the number “1” as an example. To display it on a 7-segment LED display, we would activate only segments “b” and “c,” leaving the rest turned OFF.
7-segment LED displays can be either common anode or common cathode. In a common anode display, all the anodes of the individual LEDs are connected together and linked to a positive voltage. The cathodes of each segment are then connected to individual pins and grounded to control their activation. Conversely, in a common cathode display, the cathodes of all the individual LEDs are connected together and linked to ground, while the anodes of each segment are connected to individual pins and supplied with a positive voltage.
To sum it up, a 7-segment LED display is a popular digital display technology consisting of seven LED segments arranged in the shape of an “8.” By selectively activating these segments, it can display numeric digits and some basic symbols. Whether it’s in a simple alarm clock or a sophisticated scientific instrument, these displays play a pivotal role in conveying information to the user in a clear and concise manner.
