MSD314C

MSD314C application field and working principle

MSD314C is a display module that specializes in LED character and numeric display. It uses the low current drive technology and can make each LED lighting up one after the other to ensure that information can be completely displayed. This display module is applied in the fields of industrial control equipment, digital medical instruments, remote controllers, frequency counters, data recorders and other industrial instrumentation and indication fields.

The working principle of MSD314C LED character and numeric display modules is based on a combination of LED arrays, integrated MCUs, and special display ICs. The combination of these is what makes the module capable of showing characters, numbers, or graphics. The display is powered by a special constant-voltage DC supply voltage of +5V. The integrated MCU decides which LEDs should be lit according to the provided signal. When an LED needs to be lit, the signal runs to a marker combination. The marker combination combines with an IC signal amplifier and a corresponding LED. If the signal is high, there shall be a momentary current run through the corresponding LED and then it is lit. During the entire process of lit, the other LEDs in the combination will not be affected.

The technical parameters of this display module include illuminance, current, temperature, and voltage, which can limit its performance. The luminance of white and yellow MSD314C is 5,000 mcd and the luminance of green and red MSD314C is 6,000 mcd. The best working temperature for this module is 0°C to 50°C and it is able to withstand and operate properly below -20°C and above 60°C. The supply voltage should be kept between 4V and 7V DC, and at a no-load and a full-load current consumption between 2mA and 10mA.

The MSD314C module can be a great choice for those who are looking for a reliable and efficient LED character and numeric display module. With its easy to set up and use, its wide application range, and its competitive performance parameters, the MSD314C module is one of the most popular LED display modules in use today. And with its combination of affordability, reliability, and quality, the MSD314C module is sure to provide you with a great LED display module solution for your project.
