7 Segment Display – Common Cathode – 0.56 inch – Standard Size

Description

• Size: The display measures 0.56 inches in height, which is a common size for compact 7-segment displays. The “0.56 inch” measurement typically refers to the height of the segments.
• Common Cathode: In a common cathode 7-segment display, all the cathodes (negative terminals) of the LED segments are connected together and share a common connection, while the anodes (positive terminals) of the individual segments are separate. This means you provide a positive voltage to the specific segments you want to light up.
• Seven Segments: A 7-segment display consists of seven individual segments arranged in the shape of the numeral “8.” These segments can be individually controlled to display numerical digits (0-9) and some letters (A-F).
• Applications: 7-segment displays are commonly used in digital clocks, calculators, electronic meters, scoreboards, and various devices where numeric or alphanumeric information needs to be displayed.
• Digit Display: This type of display is typically used to show numerical digits (0-9) and, in some cases, a few letters (A-F) by lighting up or turning off specific segments in different combinations.
• Multiplexing: To display different characters or digits, multiplexing is often used, where the segments are activated one at a time rapidly to give the illusion of all digits being displayed simultaneously.
• Current Limiting: When using a 7-segment display, it’s important to use current-limiting resistors to prevent excessive current flow and potential damage to the LEDs. The resistor values depend on the forward voltage of the LEDs and your power supply voltage.
• Segment Control: To display specific numbers or characters, you need to apply a specific voltage to the anodes of the desired segments while connecting the common cathode to the ground.
• Standard Size: A 0.56-inch 7-segment display is considered a standard size and is commonly used in various electronic devices and projects.
