Display Modules - LED Character and Numeric

The LTD-2701JD is a popular LED character and numeric display module primarily used in smaller data displays. The module utilizes two lines of text to display information such as customer loyalty or order data. Built on a miniature board that supports two lines of text, each line of text is capable of displaying up to 8 characters per line with 8 bright LEDs. This allows for a wide variety of data to be displayed in an efficient manner.

Application Field

The LTD-2701JD is well-suited for a variety of customer facing applications, including point-of-sale, medical and industrial imaging, machine diagnostic systems, and educational displays. It is also perfect for retail customer loyalty programs, customer coupons and promotions, and payment processing displays. Its unique design allows for easy integration into customer facing applications, and its bright LED lighting ensures that customers have no trouble seeing the text display. Furthermore, the module\'s small size allows it to be used in tight spaces.

Working principle

The LTD-2701JD operates on a simple principle. The module contains 8 rows of 8 LEDs each, arranged in two lines of text. A basic conductor pattern is used to connect one LED in each row with the power source. This causes a low voltage current to flow through the LEDs. As the voltage increases, the current begins to increase, and the LEDs begin to light up in succession. With the use of special circuitry, the LEDs remain lit until the voltage drops, at which point they will turn off again.

The LTD-2701JD also utilizes shift registers, which are used to control the LED column switching. The shift registers determine which LEDs will be illuminated, and for how long. This allows for more efficient and precise control of the LED lighting. Additionally, the LTD-2701JD also features an onboard backlight, which can be used to illuminate text in darker environments, allowing for greater visibility.

Conclusion

The LTD-2701JD is a versatile LED character and numeric display module that can be used in a variety of customer facing applications. Its miniature size allows it to be used in tight spaces, while it\'s two lines of text and 8 LEDs each line allows it to display a variety of data. The module uses a simple conductor pattern and shift registers to control the LED lighting, and a backlight allows for use in darker environments. The LTD-2701JD is a great choice for customer facing applications that require efficient, yet bright displays.
