104990138 Datasheet/PDFLED Dot Matrix and Cluster(104990138) is a common and widely used display module. It consists of a framework in which several LEDs are placed and their brightness and colour are adjusted. The modules can be used in all kinds of application ranging from automotive and industrial to consumer applications.
Application field:
LED Dot Matrix and Cluster are used in various applications in fields such as automotive and industrial, consumer, medical and educational. In automotive and industrial applications, the module can be used in process control, traffic control, lighting control, and stress analysis. In consumer applications, it can be used in home appliances, electronic signs, instrumentations, remote-controlled toys and games.
In medical applications, LED Dot Matrix and Cluster is widely employed in medical instruments, monitors, and systems for monitoring vital signs and diagnosing patients. Moreover, the module is used in educational books and smart boards that require light-sensitive features.
Working Principle:
The working principle of the LED Dot Matrix and Cluster(104990138) is based on the properties of the LEDs mounted on it, mainly the materials of the LEDs like aluminum, silicon and indium phosphide. The LEDs are arranged in a dimensional matrix which, when powered, emits light perpendicular to the matrix. The intensity, colour and direction of the light rays emitted depend on the structure, voltage and materials of the LEDs.
The LEDs in the module can be adjusted to change the colour, direction and intensity of the light rays emitted. This adjustment is done using an algorithm to control the intensity and colour of the emitted light and the relative positions of the LEDs in the matrix. The algorithm can be programmed so that the LEDs emit light according to any pattern and with predetermined intensity.
LED Dot Matrix and Cluster are also used in various communication technologies like infrared and radio frequency. The dot matrix gives the signal much higher resilience making it suitable for short range communication as well as long distance communication.
