The HDSP-8603-EF000 is a popular LED character and numeric display module. It is composed of 56 static LED characters and related LED driver circuits. The LED characters are 7 segment LED digits, so the module can display 0-9 numbers and certain characters, such as [ABCDEF].

The main application fields of the HDSP-8603-EF000 display module involve digital machines, electric appliances, and digital instruments. Specifically, they are widely used in the fields of home appliances, digital meter and credit card readers. These objects rely on the display to provide digital and statistical information, so they cannot function without the display module.

From a structural perspective, the HDSP-8603-EF000 display module consists of three major parts: main PCB, plastic case, and seven segments LED. Both plastic case and seven segments LED are fixed at the main PCB by specific fixing methods, such as plastic clips integrated with the case and welding for seven segments LED. The PCB and case are mainly used to secure the LED segments and protect them from dust, water, and other impurities.

The driving part of the module consists of an LED drive circuit and LED segments connected in series. The LED drive circuit is formed by a resistor, a transistor and other components. The working principle will be further presented in the next part.

The working principle of the HDSP-8603-EF000 module can be described in two stages—input stage and output stage. In the input stage, the external circuit provides the supply voltage for the module. Then, control signals are inputted to the drive circuit, which works in the active mode to drive specific LED segments. In the output stage, the LED drive circuits transfer the received signals to their corresponding LED segments, thus activating the display.

By briefly introducing the application field and working principle of the HDSP-8603-EF000, it is clear that it is a reliable display module for a wide range of digital instruments. With the steady supply voltage and control signals, the module can provide clear and accurate displaying information in the condition of dust proof, water proof and heat radiation.
