Shenzhen led display on modular design

Shenzhen led display because of its eye-catching , flexible content and other characteristics, have been increasingly used in advertising , information dissemination, traffic signs and other public places , and achieved good results . Shenzhen led display digital display is divided into two and the number of dot-matrix display , this article discusses only dot matrix display . Currently led display in Shenzhen are basically first by user requests, it needed to build production plants , must be repeated each time the circuit design and mechanical structure , resulting in a waste of resources, and if the user's needs change , changes will be very difficult . Shenzhen led display for an existing design to be repeated , high cost , we propose a modular design led large screen display, can achieve flexible configuration , offline operation , special effects display, and briefly describes the hardware structure and software features.
In fact, regardless of the size of the display , the principle is the same , so they could design a standardized , modular led display in Shenzhen , will different needs, only a combination of the corresponding module can be proud of . This article describes is a modular Shenzhen led display, you can change the size of the flexibility required, and can be run independently from the computer , you can achieve as blinking, scrolling display effects. Whole -screen refresh rate flickering occurs less frequently asked questions , in this design because the module is divided into small , is no longer a problem.
The actual display modules are small led driver board the same size , capable of driving led arrays with basic display features, and can receive data and commands from the control module , in addition to some common display such as blinking, scrolling , etc. are also included in the display module. Existing GB lattice Store 16 * 16 24 * 24 two kinds of , taking into account the convenience of writing software and hardware capabilities, we put the display module as a 16 × 16 matrix size. The control module is responsible for controlling each module , each module to send data and commands. The control module lattice data stored information to be displayed , each display module timed pass . The control module also comes with a small keyboard and universal asynchronous serial port , which can be used to operate the keyboard can also be used to control a computer , the computer can also be used to update the control data within the module .
