The working principle of the HDSP-3901-EF000 is quite simple. The display module consists of two separate independent circuits, with one being the master, and the other being the slave. The master receives data from the outside source and displays it on the seven-segment displays, as well as controlling the settings on the display. It then sends a signal to the slave, which responds with the corresponding data or characters. The module includes an LCD controller which processes data received through the interface and sends commands to the module. The module is thereby able to display the desired information.

The HDSP-3901-EF000 is an excellent choice for applications where high contrast and clear readability are crucial. It is user-friendly, easily programmed and provides a wide range of custom display formats. Its simple working principle makes it a reliable device, and its excellent visibility makes it well-suited for both indoor and outdoor applications.
