LDS-C402RI

LED character and numeric display modules have been widely used for various kinds of applications due to their flexibility and low power consumption. One of these modules is the LDS-C402RI. This module has a unique feature that makes it suitable for multiple applications. This article will discuss the application field and working principle of LDS-C402RI LED character and numeric display modules.

Applications

The LDS-C402RI is a four-digit seven-segment LED character and numeric display module. It is used in applications such as instrumentation and process control, meter displays, automotive applications, and even consumer products. The unique features of this module are what make it suitable for multiple applications.

The LDS-C402RI has built-in dual color LEDs for each character. This allows it to display a wide range of characters, numbers, and symbols. The module has also integrated light-emitting diodes (LEDs) for each character, enabling it to display a vivid display even at low light levels. Additionally, it is only 1.25” in width, allowing it to fit into tight spaces. It also has a low power consumption of only 16mA, making it suitable for battery use.

Working Principle

The working principle of the LDS-C402RI is quite simple. The module incorporates an array of LEDs for each digit. These LEDs are controlled by an integrated circuit driving circuitry, which is connected to the LEDs to make them light up. The driver can be divided into a multiplexer, a decoder, and a current control circuit.

The multiplexer receives the signal from the controller and passes it onto the decoder. The decoder then decodes the signal and sends it to the current control circuit. The current control circuit then controls the amount of current sent to the relevant LEDs to make them light up. As a result, the module can display a wide range of characters, numbers, and symbols.

Conclusion

The LDS-C402RI is a four-digit seven-segment LED character and numeric display module that is suitable for a wide range of applications. Its built-in dual color LEDs, low power consumption and small size make it very flexible and cost-effective. The working mechanism of the module is quite simple, as it is based on an integrated circuit driving circuitry connected to an array of LEDs. With this, it is easy to understand why this module is so popular.
