3-Digit 7-Segment Thru-Hole Display: Ultimate Guide & Reviews

With the rapid development of the electronic industry, various display devices have emerged. Among them, the 3-Digit 7-Segment Thru-Hole Display has become an essential component in many applications. This article will introduce the 3-Digit 7-Segment Thru-Hole Display, its working principle, application fields, and future development trends.

Introduction to 3-Digit 7-Segment Thru-Hole Display

The 3-Digit 7-Segment Thru-Hole Display is a kind of display device that uses seven segments to display numbers, letters, and symbols. It is composed of a light-emitting diode (LED) module and a housing. The LED module consists of seven LEDs, each representing one segment. The housing is used to protect the LED module and provide a mounting interface. The 3-Digit 7-Segment Thru-Hole Display can display up to three digits, which is widely used in various fields.

Working Principle of 3-Digit 7-Segment Thru-Hole Display

The 3-Digit 7-Segment Thru-Hole Display works based on the principle of digital encoding and decoding. The input signal is a digital signal, which is then decoded into a corresponding seven-segment code. The seven-segment code controls the on-off state of the seven LEDs, thus displaying the corresponding number, letter, or symbol.

The 7-segment code is a binary code that represents the on-off state of each segment. For example, to display the number “1”, only the first segment needs to be turned on, and the other segments need to be turned off. The 7-segment code for “1” is “0111110”.

The 3-Digit 7-Segment Thru-Hole Display usually has a common anode or common cathode structure. In a common anode structure, the anode of each LED is connected together, and the cathode of each segment is connected to the corresponding digit. In a common cathode structure, the cathode of each LED is connected together, and the anode of each segment is connected to the corresponding digit.

Application Fields of 3-Digit 7-Segment Thru-Hole Display

The 3-Digit 7-Segment Thru-Hole Display has a wide range of application fields due to its simple structure, low cost, and high brightness. The following are some typical application fields:

1. Electronic meters: Such as electricity meters, water meters, gas meters, and other energy meters.
2. Industrial automation: Such as programmable logic controllers (PLCs), sensors, and other industrial automation equipment.
3. Household appliances: Such as refrigerators, washing machines, air conditioners, and other household appliances.
4. Vehicles: Such as car odometers, speedometers, and other vehicle instruments.
5. Communication equipment: Such as telephones, modems, and other communication equipment.
