Overview of EADCD040OA1

EADCD040OA1 is a four-digit numeric display module in the category of LED Character and Numeric. It encompasses a four-digit display featuring seven LEDs in each segment, four of which are grouped in the center and three positioned at the edges. It is applicable to a wide range of applications such as consumer electronics and home appliances in both commercial and industrial sectors.

Application Field

The EADCD040OA1 display module can be used in consumer electronics, including watches, calculators, industrial pumps, and TVs. It is also applicable to home appliances, from ovens and refrigerators to air conditioners and fans. Furthermore, the EADCD040OA1 display module can be applied to commercial equipment, from motors and fans in manufacturing to automation and data systems in the banking industry.

Working Principle

The EADCD040OA1 LED display module works using four 7-segment displays that are constituted by four individual anodes and seven common cathodes. For each digit, the anode voltage is varied, while the required display segment is kept active. When the anode voltage is applied, the active-window is set and the LEDs in the segment are illuminated. In order to ensure that each segment receives the proper current, the common cathode is connected to a segment resistor. Therefore, when the required display segment is set and the current is constant, no matter how much the anode voltage fluctuates, the display segment remains illuminated.

Conclusion

The EADCD040OA1 is a four-digit numeric display module in the category of LED Character and Numeric, applicable to a wide range of applications such as consumer electronics and home appliances in commercial and industrial sectors. It works using four 7-segment displays that are composed of four individual anodes and seven common cathodes. When the required display segment is set and the current is constant, no matter how much the anode voltage fluctuates, the display segment remains illuminated. Consequently, the EADCD040OA1 LED display module is a reliable, cost-effective option for displays in almost any type of device.
