Today, Liancheng sent a small editor to share with you what components are the led display screens composed of?
LED display (LED display) is a kind of flat panel display, which is composed of small LED module panels, and is used to display various information such as text, images, videos, video signals and so on. The components are as follows:
1. LED unit board: It is one of the core components of LED display. The quality of the unit board directly affects the display effect of the display. The unit board is composed of LED module, driver chip and PCB circuit board. The LED module is actually made up of a lot of LED light-emitting points encapsulated by resin or plastic dot matrix.
Second, the connection: it can be divided into data lines, transmission lines and power lines. The data cable is the cable used to connect the control card and the LED unit board. The transmission line is used to connect the control card and the computer. The power cord is used to connect the power supply, the control card and the LED unit board. The diameter of the copper core of the power cord connecting the unit board is not less than 1mm.
3. Power supply: The power supply generally uses a switching power supply, 220V input and 5V DC output. It should be pointed out that since the LED display screen is a precision electronic device, a switching power supply must be used instead of a transformer.
4. Control card: We recommend using a low-cost strip screen control card, which can control a 1/16-sweep 256x16-dot two-color screen, and can assemble the most cost-effective LED screen. The control card is an asynchronous card, that is to say, the card can save the information after power off, and can display the information stored in it without connecting to a PC.
It is recommended that you choose a large manufacturer with quality assurance when purchasing LED displays. LCF Lighting specializes in the research and development, manufacturing, sales and service of LED displays, and provides customers with professional solutions!
