The QBSS391CB is categorized as a type of display module, particularly an LED character and numeric module. This module uses both cathode and anode pins, each of which can consist of single or multiple colored LEDs. These LEDs are arranged in a certain way that allows the user to create a rang of characters, images, logos and more. The QBSS391CB is used in a variety of different applications, including numerical and character display of liquid crystal displays (LCDs) and light emitting diode (LED) displays. It is also suitable for embedded systems and small-sized displays.

The QBSS391CB LED character and numeric module is equipped with a controller chip, an LED display module, connectors and I/O boards. It is powered by a single +5 V input voltage, using a pin header, which makes it compatible with a vast array of circuit boards. The module is FCC Certified and CE Certified, ensuring safety and performance. Furthermore, the module is RoHS compliant, making it an environmentally friendly solution.

The QBSS391CB module measures 2.94" x 1.78" x 0.62", and contains 8-line segments and 8- rows of characters. It features 120 single LEDs and 120 anodes, which make it an excellent choice for displaying various letters, numbers, symbols and images. The module A/D scanning operates a multiplex technique and offers the user a bright and uniform display. Since it is an LED display, it does not require a backlight, so it does not consume as much power as LCDs.

As for its working principle, the QBSS391CB LED character and numeric module features a controller chip which sends data signals to the LED display module. This module is then able to display the characters, logos and images accurately. The functioning is based on a driver IC (integrated circuit) chip, which has special ports with data in and out, clock in and out and enable in and out. It has an external power supply, allowing the integrated circuit chip to control the current of the LED to adjust the brightness and adjust the size of the display screen. This integrated circuit chip also filters the output image and helps to prevent the flickering of an image.

The QBSS391CB LED character and numeric module is a highly adaptable and reliable module for a variety of applications. Thanks to its LED display and its efficient functioning, it is a suitable choice for embedded systems, LCDs, LED displays and other small size display solutions. It supports a wide range of characters and images, is safe, RoHS compliant, and uses very little power, contributing to a greener environment.
