Display Modules - LED Character and Numeric

HDSP-U213-CD000 is a kind of seven-segment, common anode LED display module. This module combines four digits of each 0.36 inch, seven-segment, common anode LED displays with internal decoder and resistors. The module can be used to display number data. It is manufactured by Hewlett-Packard (HP).

Application Field of HDSP-U213-CD000

The HDSP-U213-CD000 module has a broad application field. Its application field can be divided into several categories, such as instrument displays, scoreboards, measuring equipment and industrial control systems. It is widely used in numeric displays, and the performance of reading numeric data is steady and reliable. The module is ideal for displaying numerical data and alphabetical data. It is also suitable for occasions that require accurate measurement data, such as temperature, pressure, and clock time, etc. Some typical applications are digital clocks, digital flags, speed monitors, weighing instruments, and more.

Working Principle of HDSP-U213-CD000

The working principle of the module is divided into several parts: power supply, the segment driver, the decoder, and the resistor.

First of all, the power supply supplies power to the module. It provides a suitable working voltage betwee 3.8V and 6V for the LED segments. Secondly, the segment driver is in charge of driving the LED segments. It can turn on one LED at a time and bring them to the ready state. Then, the decoder is responsible for decoding input data signals into appropriate segment formatting. Finally, the resistor is used to adjust the current and prevent the LED from being damaged.

All the parts of the module work in coordination, which makes HDSP-U213-CD000 a reliable module for displaying data. Its simple structure and stable performance make it widely used in a variety of applications.
