What is the difference between the synchronization control of full -color LED display and asynchronous control

　　Synchronization refers to the content of the computer screen synchronizing the content of the full -color LED display. The asynchronous LED display display has been sent to the card with fixed content. In terms of price, it is generally more expensive, but the large -scale LED asynchronous control card is not low. Determine whether the full -color LED display is synchronized or asynchronous display. According to its purpose: For example, the remaining ticket is displayed in real -time, which is synchronized in real time. The LED door screen at the door of the flower shop generally displays fixed slogans, which are basically asynchronous.

　　CRT synchronization display refers to the display content of the full -color LED display in real time and synchronously to reflect the display content on the computer CRT display.

　　The maximum control of the control system of the synchronous control system to send a card is 1280 points × 1024 points. The receiving card in the full -color LED display control system is best for a box and a receiver card.

　　Asynchronous control refers to the computers that edit the editing content, and send them to the receiving card of the full -color LED display through the communication program. Wait for cycle to play.

　　The maximum control system for the control system of the indoor full -color LED display in the interior is 2048 points × 256 points.

　　The maximum control system of the outdoor full -color LED display control system is 2048 points × 128 points.

　　Synchronous control and asynchronous control refer to the control method of the relative computer's full -color LED display:

　　The so -called synchronous control system refers to the content displayed by the full -color LED display displayed by the full -color LED display and the real -time LED display control system of the computer display. A area of the computer display is exactly the same as the full -color LED display display content. For example, the control systems such as Lingxing Rain, De Peuda, Nova and other control systems are synchronized control systems. The traditional methods are sending cards+receiving cards, and there are no transmission cards.

　　The asynchronous control system is also called the offline control system. It is to store the computer editing data in advance in the full -color LED display control system. After the computer is shut down, it will not affect the normal display of the full -color LED display. Simply put, use a control card, edit the content of the computer, or use a U disk to place the content in the control card, and then only one control card controls the full -color LED display without computer control.
