4-Digit 7-Segment Thru-Hole Display is a type of electronic display device that is widely used in various industries for displaying numerical information. It consists of four seven-segment displays, each capable of displaying one digit. This article aims to provide an in-depth introduction to the 4-Digit 7-Segment Thru-Hole Display, including its structure, working principle, applications, and market trends.
Structure of 4-Digit 7-Segment Thru-Hole Display
The 4-Digit 7-Segment Thru-Hole Display is composed of four individual seven-segment displays. Each seven-segment display is made up of seven LED segments, which can be turned on or off to form different digits and symbols. The four seven-segment displays are arranged in a linear fashion, with each display representing one digit. The segments are connected to a common anode or cathode, depending on the type of display.
The thru-hole design of the 4-Digit 7-Segment Display allows it to be mounted on a printed circuit board (PCB) using through-hole technology. This makes it easy to assemble and connect the display to the electronic circuit. The display module typically includes the LED segments, a common anode or cathode, and a set of leads for connecting to the circuit.
Working Principle of 4-Digit 7-Segment Thru-Hole Display
The 4-Digit 7-Segment Thru-Hole Display operates based on the principle of light-emitting diodes (LEDs). Each LED segment is made of a semiconductor material that emits light when an electric current passes through it. The seven segments in the display are arranged in a specific pattern to form the digits 0 to 9 and some additional symbols.
To display a specific digit, the corresponding LED segments are turned on while the others are turned off. For example, to display the digit “1”, only the first and fourth segments are turned on, while the rest remain off. The display driver circuit controls the current flowing through each segment, enabling the desired digit or symbol to be displayed.
The 4-Digit 7-Segment Thru-Hole Display can be controlled using various methods, such as common anode or cathode, multiplexing, or scanning. In a common anode or cathode configuration, the display driver circuit drives the segments by applying a high or low voltage to the common anode or cathode, respectively. Multiplexing and scanning techniques allow multiple displays to be controlled using fewer pins, thereby reducing the complexity of the circuit design.
