Introduction to LDS-AA404RI

OKW’s LDS-AA404RI display module is a high-tech LED display designed for use in high-end applications. This module features a 3-in-1 design that allows it to display red and white numbers and characters, as well as blue characters, all in one unit. This allows for a highly efficient and flexible solution in applications requiring multiple colors.

Applications and Advantages of LDS-AA404RI

The LDS-AA404RI display module is well-suited for a variety of applications, such as LED sign boards and message boards, in businesses, factories, parking lots, and more. It can also be used in advertising and other visual communication applications. Its 3-in-1 design offers several advantages, such as improved visual impact, higher contrast levels, better space utilization, and easier programming.

Working Principle of LDS-AA404RI

The LDS-AA404RI display module employs a dual light-emitting diode (LED) system consisting of two LEDs of different colors. The light source of each LED is separated so that the light emitted from each LED has no overlap with the other. The red LED is dedicated to the red characters, while the white LED is dedicated to both red and white characters. The blue LED is devoted to the blue characters. A two-dimensional array of LEDs is arranged in a row-column matrix to provide the necessary light for each character. The display module then uses an integrated circuit (IC) to control the LEDs, converting data input into the correct position for each character. To ensure low power consumption, the module contains a built-in charge-pump circuit that provides a stable power supply for the LEDs.

Conclusion

The LDS-AA404RI is a highly efficient and versatile display module that can enhance the visual impact of a variety of applications. With its 3-in-1 design, it offers several advantages, such as improved visual impact, higher contrast levels, better space utilization, and easier programming. Additionally, its dual LED system and charge-pump circuit ensure it has a low power consumption, making it an ideal choice for applications requiring multiple colors.
