QBD40AG0 is an LED character and numeric display module and a popular choice for engineers who need to design embedded and industrial projects requiring an LED display. It features an advanced, modern design and is compact, reliable and cost-effective.
Overview
QBD40AG0 is a four-digit LED character and numeric display module which features LED\'s illuminated by a circuit of four series resistors and five dynamic seperators. The LED\'s used in this module are small in size and low in power consumption. The module is designed to be mounted on PCBs and is often used in production line applications, as well as a variety of other general purpose applications.
Application Fields
QBD40AG0 can be used in a variety of applications, including clocks, timers, indicators and controllers. It can be used to display alphanumeric characters, such as A-F, 0-9 or special characters. It is also a popular choice for designers who need to build production line projects requiring a single display. In addition, it is also used in robotics projects and other embedded systems, as well as medical and military applications.
Features
QBD40AG0 offers a range of features, including adjustable brightness and contrast settings, adjustable character spacing and size, as well as an adjustable number of dimmers to increase or decrease the appearance of the display. It is also equipped with a protective cover to ensure its longevity and ensure a high-quality output. The module is also resistant to corrosion and offers an extended operating temperature range.
Working Principle
QBD40AG0 uses a simple single-digit current baseloop circuit with a negative ground to generate the LEDs. This circuit works by drawing a current through the power source to the LEDs when a negative voltage is applied. As the voltage increases, the voltage across the resistor increases, causing the LED\'s to turn on. The LED\'s are then dimmed or turned off depending on the input voltage. This circuit ensures the module is able to maintain a constant brightness.
Conclusion
QBD40AG0 is a comprehensive LED character and numeric display module. Its features, including adjustable brightness and contrast settings and adjustable character spacing and size, make it an ideal choice for anyone looking for a reliable, cost-effective displaying option for their project. Its advanced circuit and single-digit current baseloop circuit ensure a prolonged lifespan and high-quality output.
