The LSHD-7801 is a seven-segment display digital module widely used in a variety of applications such as temperature measurement and display, mass production line production count status display, mid-term check, etc. It is a digital segment combination display module suitable for the input of eight digital numbers, which can show common numbers 0~9 and some special characters or symbols. Below, we will discuss in detail the application field and working principle of the LSHD-7801.

Application Field

The LSHD-7801 is mainly used to display digital characters on commercial test instruments, or used in a variety of occasions where the display of digital characters is required. For example, it can be used in temperature measurement and display, mass production line production count status display, mid-term check, etc. It can also be used in combination with control keys to form a key input control system. And the product can receive an external trigger signal, such as an external light source, can be used as a trigger set. It also has various character interfaces, including 7-segment characters, 8 x 7-segment characters, 10 x 7-segment characters, 12 x 7-segment characters, 16-segment characters, 16 x 16-segment characters, 10 x 8-segment characters, 8-segment characters, etc.

Working Principle

The working principle of a digital segment combination display module LSHD-7801 is achieved by using a seven-segment display. This display consists of 8 segments, and each segment includes 7 segments. To display the digital characters 0-9, the corresponding digital numbers need to correspond to each segment of 0-9. Then the current will be sent to the correspond segment for lighting. For example, for displaying character “4”, the current will be sent to the corresponding “4” segment, and all other segments will be powered off. By combining the several segments, it can display the digital characters 0-9.

Since the LSHD-7801 is a seven-segment display digital module, it is composed of a micro-programmed controller, which can count the data automatically and display it in the seven-segment display by sending corresponding current to the segment in the display. And the module has polarity reverse protection, and the circuit design is simple and reliable. Thus, the working reliability of the digital display module can reach up to a very high level.

Conclusion

In conclusion, the LSHD-7801 is a seven-segment display digital module used in a variety of occasions where characters display is required. Its working principle is achieved by sending corresponding digital numbers to the corresponding segment for lighting and constantly switching the brightness of the segment for displaying digital characters 0-9 and other certain special characters or symbols if needed. Thus, the LSHD-7801 is widely used in various commercial instruments and occasions where characters display is required.
