HDSP-5558 is a six‑digit, seven‑segment display device, mainly used to display numerical values. It is one of the most popular display devices and is widely used in a variety of applications, ranging from industrial monitors to medical equipment. In this article, we’ll take a look at its application field and working principle.

Application Field

HDSP-5558 is the perfect choice for applications that require high visibility, performance and reliability. It is well-suited for displaying numerical values in various applications, such as industrial control, medical equipment, vending machines, security systems, consumer electronics and general displays. Due to its low power consumption and high visibility, this device is a great choice for energy-conscious, low-bandwidth applications.

Working Principle

The HDSP-5558 is based on a classic seven-segment LED display, which includes seven individual LED segments that are arranged in a rectangular form. Each LED segment is controlled by a dedicated logic pin, which when set to a 1 or high-logic state, will turn on the corresponding LED segment. The HDSP-5558 is powered by DC voltage, typically 3.2V to 5V depending on the specific device.

The HDSP-5558 supports 8-bit binary values (in codes 0 - F), and also supports decoded BCD code. When the BCD code is provided, then the display automatically converts it to a seven-segment code, which will be used to control the LEDs. The device supports multiple modes, such as brightness control, digit select, refresh rate, etc. Based on these control signals, the HDSP-5558 can be used to control the display of numeric or certain symbols, such as “:” and “-”.

Conclusion

In conclusion, the HDSP-5558 is a versatile and popular seven-segment LED display device with many use cases. It is well suited for applications requiring high visibility and low power consumption, including industrial control, medical equipment, vending machines, consumer electronics, and more. It supports multiple modes, such as brightness control, digit select, refresh rate, and more. Now you should have an understanding of its application field and working principle.
