Description
The description “1 digit 7 segment red cathode” refers to a specific type of 7-segment display with the following characteristics:
Digit Count:
The display is designed to show one digit at a time. A 7-segment display typically consists of seven individual LED segments arranged in a pattern to represent numerical digits (0-9) and sometimes a few additional symbols.
7-Segment Configuration:
The display utilizes a 7-segment configuration, where each digit is formed by illuminating specific segments. The segments are usually labeled A through G.
Color:
The display is red, indicating that the emitted light is in the red wavelength spectrum. Different colors are available for 7-segment displays, and the choice of color can have applications in aesthetics or specific signaling requirements.
Cathode:
The term “cathode” specifies the type of connection used for the LEDs. In a cathode-type 7-segment display, the cathodes of the individual LEDs are commonly connected together and share a common connection. When a voltage is applied to the anodes of specific segments, those segments will light up.
Common Cathode Connection:
With a common cathode 7-segment display, the cathode of each LED segment is connected together, and this common cathode is connected to the ground (GND) or the low side of the power supply. To illuminate a specific segment, a positive voltage is applied to the anode of that segment.
Applications:
7-segment displays, including 1-digit red cathode displays, are commonly used in various electronic applications where numerical or simple alphanumeric information needs to be visually displayed. Examples include digital clocks, temperature displays, counters, and instrumentation.
Digit Height:
The size of the digits, often measured in millimeters or inches, determines how large or small the characters will appear on the display.
Compatibility:
It’s important to ensure that the display is compatible with the voltage levels and current requirements of the circuit in which it will be used.
When integrating a 1-digit 7-segment display into a circuit, you’ll need to refer to the datasheet or specifications provided by the manufacturer. The datasheet will provide information about pin configuration, electrical characteristics, and connection details, ensuring proper usage in your specific application.
