XDVG25A Application Field and Working Principle

XDVG25A are display modules used in LED Character and Numeric applications. Designed to be small in size and energy efficient, they offer an OLED solution for projects that demand better visual output and longer life expectancy. These modules contain an LED array of red, green and white colors, along with a controller that can be programmed to display text or numerical data. They are suitable for applications such as instrumentation, medical equipment and vehicles.

Application Field

XDVG25A modules are mainly used in applications that demand visual output with high contrast. These modules are well-suited to be used in medical applications, where clear and legible output is paramount. Additionally, they offer better energy efficiency which is ideal for projects that require longer battery life and lower power consumption. They can also be used in automobiles, instrumentation, POS systems and other such applications that require virtual display data.

Working Principle

XDVG25A modules are designed with an LED array of red, green and white colors along with an integrated driver IC. This IC can be used to program the modules for displaying text or numerical data. The LED array is composed of a single row of three LED sections which can be programmed to display characters or numericals from 0 to 9. The LED sections are driven via current sink outputs, meaning they are grounded through their own pins. By using the ‘blank’ pin, the LED array can be activated or disabled to provide the desired visual output.

The modules are equipped with low power consumption and minimized heat dissipation. The LED array current is adjustable via external resistor and adjustable through pulse width modulation. The modules can be programmed using serial communication protocols, such as UART and I2C. Additionally, they offer various features such as adjustable display speed, adjustable illumination, contrast and brightness.

Conclusion

XDVG25A modules are designed for LED Character and Numeric applications. They are small in size and offer low power consumption, making them perfect for projects that demand better visual output and longer life expectancy. The integrated driver IC allows them to be programmed to display text or numerical data, and they are suitable for medical, instrumentation, vehicles and other applications. Overall, the XDVG25A provides a great solution for applications that require virtual display data.
