What are the types of LED screen controllers? LED screens are divided according to their functions. For example, there are monochrome LED screens that specifically display subtitle information, and there are red, green, and yellow bank and securities market information announcement screens. This type of LED screen is also used in train timetables at stations and train stations. The other is the most widely used full-color LED screen at present, and all information can be displayed. Since there are so many types of LED screens, the working methods of the controllers must also be very different. Let’s talk about their direct differences one by one. The controller of the monochrome LED screen is relatively simple, and the controller of the monochrome screen is mainly Mainly offline, which is often referred to as an asynchronous control system, the main feature of the offline LED screen controller is to download the information to be played from the computer and play it in a loop on the controller. The supported interfaces include U disk and serial port , network port, etc., as well as wireless WIFI, and the latest mobile phone WeChat control is developed, which is really getting smarter and smarter. The dual-color LED screen is somewhat the same as the single-color control method. If the display screen is large, a synchronous controller is required.
At present, the full-color LED display controller is mainly based on synchronization. The main feature is that the sending signal is fast, and it can flexibly play various video source programs on the computer. It can be switched to the LED screen. To put it simply, the LED screen can be understood as another monitor copied from the computer. .
