LA-301MB Application Field and Working Principle
LA-301MB belongs to the display modules - LED character and numeric. It provides a perfect human-machine interactive solution for industrial control system. This module is a dynamic dot matrix display module and is suitable for dynamic display of a variety of data. It is mainly used in industrial monitoring and display, information release, printing machines, automatic vending machines and other fields.
The main components of the LA-301MB include a wide temperature range LED dot matrix display, a display controller, and a flat cable for connecting the two. The display controller includes an MCU, a serial port module, and a 1000 Hz voltage generator. It is used to generate programmed instruction signals sent from the main controller of the industrial control system to drive and control the LED dot matrix display. Moreover, LA-301MB is standardly equipped with basic light-control switches, allowing the LED dot matrix display to be turned on or off according to the ambient condition.
The controller is mainly responsible for driving and control of LED dot matrix. In addition, it has the function of storage and display logic, making the working state of the module more stable. The communication between the controller and the main controller mainly relies on the serial port, and it can realize the 256 level grayscale display with no interference. Finally, the user can have access to the external device through the operation instructions and configure different display modes to meet different needs.
In conclusion, it can be seen that the working principle of LA-301MB is mainly composed of two components: display controller and LED dot matrix. The display controller is mainly responsible for receiving instructions from the main controller and generating the instructions for driving and controlling the LED dot matrix display. In the meantime, the LED dot matrix display is mainly used to present information dynamically according to the instructions received.
