Introduction to 104990119 LED Character and Numeric Modules

LED Character and Numeric Modules are electronic components used to display text or numbers in way that is more visible than for an LCD component. These modules have become increasingly popular due to their lightweight, efficient nature and long lifespan. The 104990119 LED Character and Numeric Module is a common product manufactured by PPI and is used in many types of applications.

Overview of the 104990119 Module

The 104990119 module is an indoor type character module and contains an 8x8 dot matrix. The module is available in both common anode and common cathode configurations. It is designed for easy mounting and uses screw type terminations. The module also has a built-in shift register for the drive circuitry and control logic, which makes it possible to reduce the number of interface pins. The dimensions of the module are 24.77 mm (0.97 inches) x 20.70 mm (0.81 inches).

Application Field and Working Principle

The 104990119 LED Character and Numeric Module is suitable for any application where easy mounting, excellent visibility, and long-term reliability are required. It could be used in a wide range of products such as medical and industrial instruments, automated teller machines, voting machines, and measuring instruments.The module’s working principle is relatively straightforward. A shift register is used to generate data signals for the LED matrix. When the external control circuit sends a low level signal to the data input pin of the shift register, a single data bit is output from the shift register. This data bit is then sent to an LED drive circuit. A transistor drive circuit is used to turn on and off the LED elements according to the value of the data bit. When a current flows through the LED element, the LED light is illuminated according to its brightness. This process is repeated for all the LED elements on the matrix until the entire image is displayed.

Conclusion

The 104990119 LED Character and Numeric Module is a great choice for applications requiring a high-visibility, low-cost, and long-term reliable display solution. It is easy to install, efficient, and has a simple working principle. If you are looking for an effective and reliable display solution, the 104990119 LED Character and Numeric Module is an excellent choice.
