LED Character and Numeric displays are display modules typically used in everyday electronics and commercial applications. Among these is the LTS-4301P model. This reference guide provides an introduction to the LTS-4301P\'s application field and working principle.

Applications

The LTS-4301P module is a 14 segment LED display module with a wide variety of applications. It is ideal for customer rating systems, medical device displays, automotive displays and many other commercial applications. It features a wide viewing angle and a low power consumption, making it ideal for many applications. Additionally, the module is highly durable and offers a temperature range of -25~+80℃. This makes it suitable for use in a number environments and conditions.

Working Principle

The LTS-4301P module is a four-digit, fourteen segment display organized by eight columns and four rows. The segments are driven by a common-cathode supply design, which works in a positive polarity. The anode cathode connection of this module comprises a shared cathode segment connection and 16 single digit segment anodes. The resulting anode voltage is high enough to diode the inverse current of the relay current that provides the set illumination intensity of the segments. This supply voltage plus the principles of electromagnetic force (EMF) dictate the working principle of the module.

The module is powered through a polarized plug connector which needs to be connected to a power source. When this is connected, the current is supplied to the drive circuit, producing an electromagnetic field near the drive line. This field is then converted into a voltage by the drive, causing the segments to illuminate. The segment anodes remain connected to the drive voltage line, allowing the forward voltage to remain relatively constant. However, as the electromagnetic field is disrupted by movement, the anode voltage of the segments changes rapidly, resulting in separate, visible segments.

Conclusion

The LTS-4301P module is an ideal choice for a wide variety of applications, including customer rating systems, medical device displays, automotive displays, and many others. It features a wide viewing angle and a low power consumption, making it energy efficient. Additionally, its high temperature range and durability make it suitable for use in a variety of environments. By understanding its application field and working principle, engineers and technicians can more effectively design applications that utilize this technology.
