Abstract: The led electronic
display contains different models and specifications. The led electronic display contains different models and specifications. Secondly, the led electronic display belongs to engineering equipment and requires many supporting parts, such as the LED screen, the control part, the power distribution part, and the structure. Part, installation and debugging, etc., so we must first determine the use environment of the led electronic display screen, and what specifications are suitable. 1. LED electronic display screen body cost: generally calculated according to how much money per square meter, that is, the common LED electronic display price is xxx yuan/m2, and the LED electronic display type and materials used are different, and the price will also be the difference. The LED screen quotation includes a complete set of LED color screen requirements: die, module circuit board, IC driver chip, module power supply, cold-rolled plate box and plastic mask, and all cables and connecting wires inside the LED electronic display and so on. 2. Controlling the computer: the necessary equipment for controlling the led electronic display screen, requires configuration requirements or higher: dual-core CPU, 2G memory, independent graphics card with 512M or more, and the motherboard must have a PCI slot. 3. Control system cost: the cost of the sending card and receiving card of the led electronic display screen. Generally, one screen only needs one sending card, which is installed in the computer host, and the number of sending cards is n. The use of the control card is mainly based on the size of the led electronic display screen to determine the number. Generally speaking, the larger the area and the higher the density of the LED electronic display screen, the more the number of receiving cards used. 4. Power distribution cabinet: small-area led electronic display screens are not required; it is recommended that the LED electronic display screens with a maximum power consumption of 10KW or more can provide voltage power and current for the stable operation of the LED electronic display devices, effectively preventing LEDs The electronic display screen has a fault such as a power switch and a box. 5. Audio + power amplifier: a device that allows simultaneous video playback on the led electronic display screen to make sound, generally equipped with 1 power amplifier and 2 audio. 6. Multi-function card: for indoor led electronic display, the main function is to intelligently adjust the brightness, temperature and other values u200bu200bof the full-color led electronic display in a period of time, intelligently adjust to achieve energy saving and power saving, and extend the service life of the led electronic display; indoors; The led electronic display can not be used. 7. Air conditioning: cooling equipment, outdoor led electronic display screens of more than 20m2 must be equipped with air conditioners by the manufacturer to ensure the normal operation of the screen and prolong the service life of the components of the led electronic display screen. Generally, indoor screens or small-area led electronic displays are not required; large-area indoor led displays are strongly recommended to be equipped with wall-mounted air conditioners to effectively cool down, to ensure that the led electronic displays can travel normally at high temperatures and reduce the failure rate. 8. Video capture card: TV card, a small card, installed in the computer, coupled with the corresponding driver software, can allow the led electronic display screen to play cable TV channels simultaneously, whether it is needed, users can buy it by themselves. The price is not expensive. 9. Lightning arrester: used for outdoor led electronic displays, mainly lightning protection devices; indoor led electronic displays can not be used. 10. LED playback software: including computer system software, LED video playback software, etc. 11. LED video processor is generally provided free of charge: mainly to improve the overall display effect and functional application of the large screen, and to fully tap the value of the LED electronic display. Solve the problems of various video signal access, processing and display, and can complete the format conversion problem among many signal formats. There are many brands and models of LED video processors with different prices. 12. Freight: depending on the delivery distance budget, I believe that the majority of customers are still acceptable. The customer can also be responsible for the cost, and the actual report is enough. 13. Steel structure, manual installation: the bracket used to fix and install the led electronic display screen, generally uses a steel frame structure, and aluminum-plastic panels or stainless steel edging materials. Including manual installation costs (recommendation: the steel frame structure design drawings can be provided by the manufacturer for free, and the customer can find a local manufacturer to make it. The production is simple and can be completed by ordinary workers, with low cost and easy installation)
