The HDSP-5551 is a commonly used display module designed for the purpose of providing numeric and character information in a simple, easy to read format. The HDSP-5551 is a character display module typically used in industrial applications and LED (light emitting diode) displays. The HDSP-5551 utilizes a 5×7 dot matrix LED display with 5 digits, three display positions, and one display control line.

The HDSP-5551 operates on a constant current source for each character and it is composed of fifty-five LED elements. It can be used in a variety of applications due to its compact size and simple interface. These applications include general purpose controller displays, clock and calendar displays, home appliance displays, and many industrial data displays.

The HDSP-5551 works on the principle of a constant current source. This means that the brightness of each LED element is determined by a single fixed current source. The amount of current that flows through each LED element is the same no matter what the required brightness is. This keeps all of the LED elements lighting at the same intensity, so when one element goes out the rest of them stay on at the same brightness.

The working voltage of the HDSP-5551 is between 4.2V and 7.5V and the display uses a constant current to ensure that all the elements are lighting uniformly regardless of the number of digits in a display. This allows the same amount of current to be used in each element regardless of the number of digits being used which helps to conserve energy and prolong the life of the LEDs.

The HDSP-5551 is a popular display module and its wide range of applications makes it ideal for many different types of applications. It has a simple interface and its small size enables it to be used in applications where space is limited. Its use of a constant current source ensures that all elements are lighting at the same intensity, making it a reliable and consistent choice.
