It is a general-purpose LED display module with bright display capability in a compact package. Utilizing solid-state technology, it is highly reliable, easy to install and maintain.

Application Field

LED display module 104990130 is ideal for applications requiring a high brightness display, such as medical instrumentation, process control, transport systems, automotive instruments, etc. It is available with various display formats, such as numeric, alphanumeric, and multi‑segment displays. It features a wide operating temperature range and low power consumption, making it suitable for rugged and low power applications.

Working Principle

LED display module 104990130 operates on a standard internal oscillator and can be programmed to display an array of LED elements. This LED module features an array of low-power LEDs that can be individually driven and combined to create a large display with up to 16 LEDs in each character. The power supply for the LED module is provided using an external power supply transistor circuit. The module is programmed using a serial or parallel interface.

The LEDs are driven using a dedicated serial input/output (SIO) port to control the intensity, position and size of the displayed characters. The data and control signals for the module are transmitted through the SIO port. Data is stored in the module’s internal memory for easy access and can be updated as required.

The LEDs are controlled by a driver circuit and the resulting display can be completely customized. For example, the intensity of the LEDs can be adjusted to ensure an optimal viewing angle, while the size of the letters and numbers can be set to ensure a consistent viewing distance. The overall brightness, contrast and color of the display is adjustable using a combination of potentiometers and trimmers.

Conclusion

LED display module 104990130 is a reliable and efficient LED module for meter and instrumentation applications. This module is suitable for a wide range of applications, due to its wide operating temperature range and low power consumption. It can be programmed to display an array of LED elements, and its brightness and contrast can be adjusted to suit the desired viewing angle. Moreover, this module offers a serial or parallel interface for data transmission and programming, making it easy to install and maintain.
