The LED full-color display control card is the main control system installed in the LED display. Each display needs to be installed with a control card to start the LED full-color screen work, including publishing text, pictures, videos and other information. The LED display control card is the core component of the LED graphic display. It is responsible for receiving the picture display information from the serial port of the computer, placing it in the frame memory, and generating the serial display data and scanning control required by the LED display according to the partition drive mode. timing. The effect of the LED display screen is related to it.
To put it simply: the synchronous control card of the LED full-color display is to use the computer and the LED display to work together, rely on the computer to store the data, and then send the card to the control card in the LED display. content, and what content is displayed on the LED display at the same time.
LED full-color display asynchronous control card only needs to compile the data through a computer or mobile phone, and send it to the control card through different transmission methods (including U disk, GSM SMS, GPRS wireless), the data coexist, and the screen can continue after disconnection. Play content.
Most of the LED synchronization control card is a communication card used by the LED full-color screen. It is installed inside the full-color screen. It is mainly used to transmit and publish some color pictures, warning languages or video files. Fewer venues. Such as squares, railway stations, and other prominent locations of units;
Most of the single and double-color display screens of the LED asynchronous control card will be selected. It is mainly used to transmit simple text, pictures and other documents. Most of them are installed in the door, supermarket, bus, taxi, etc. on a small display.
What should I pay attention to when using the LED display control card?
Different brands of control cards and corresponding installation software are different. The same brand is also divided into different models, the function is very different. The commonly used simple non-partitioned control card for small-area monochrome screens is cost-effective; while for larger areas, partitioned control cards can be used, and the price is higher.
What are the connection methods of the LED display control card?
The main ways of connecting the control card and the computer are: network port (TCP/IP), serial port (RS232, RS485), U disk conduction, GPRS wireless connection, Zigbee wireless connection and other main methods.
How to choose LED display control card?
First, understand the specifications and dimensions of the LED display, calculate the number of points, and know the effect you need, whether it is synchronous or asynchronous, and whether secondary development is required; then, determine the synchronous and asynchronous, determine the effect, determine the range of points, and determine the price range, Finally, determine the card; choose the most suitable control card, not necessarily the most suitable one with high price and good quality. In the end, the software is not suitable for you and your customers.
