LED display screen belongs to a set of relatively complex electronic equipment, usually composed of display unit, steel structure frame, control system, power distribution system and other peripherals. The quotation scheme of led display is relatively detailed, which can be mainly divided into the following 15 aspects. I hope it can help LED engineering companies and sales personnel of LED display manufacturers to refer to.

  1. The cost of the led display screen: it is generally calculated according to how much per square meter, that is, the common led display price is xxx yuan/m2, and the price of the display screen is different depending on the model and material used. The screen quotation includes a full set of LED color screen requirements: die, module circuit board, IC driver chip, module power supply, steel box and plastic mask, as well as all cables and connecting lines inside the LED display. Generally, the price includes tax, this may be different, please ask for specific consultation.

 2. Control system cost: that is, the cost of sending and receiving cards for the led display screen. Generally, one screen only needs one sending card, which is installed in the computer host. The use of the control card is mainly determined by the size of the led display. Generally speaking, the larger the area and the higher the density of the display screen, the more receiving cards are used.

 3. Control computer: The necessary equipment for controlling the led display screen requires configuration requirements or higher: dual-core CPU, 2G memory, independent graphics card above 512M, and the motherboard must have a PCI slot.

 4. Audio + power amplifier: The device that makes the LED display synchronously play the video and emit sound, generally equipped with 1 power amplifier and 2 audio.

 5. Power distribution cabinet: Small-area LED display can be used without it; it is recommended that the display with a maximum power consumption of more than 10KW be equipped with a voltage supply current for the stable operation of each device of the display device, effectively preventing the display power supply switch from jumping. box, etc. failure.

 6. Air conditioning: cooling equipment, outdoor led display screens above 28m2 must be equipped with air conditioners by the manufacturer to ensure the normal operation of the screen body and prolong the service life of the components of the display screen. Generally, indoor screens or small-area display screens are not required; large-area indoor screens are strongly recommended to be equipped with wall-mounted air conditioners, which can effectively cool the temperature and ensure the normal travel of the display screen under high temperature, reducing the failure rate.

 7. Multi-function card: used for indoor LED display, the main function is to intelligently adjust the brightness, temperature and other values of Tuosheng photoelectric LED display by time period, intelligent adjustment to achieve energy saving and power saving, prolong the service life of LED display; indoor LED display Can not be used.

 8. Lightning arrester: used for outdoor LED display, mainly for lightning protection; indoor display can not be used.

 9. Video capture card: TV card, a small card, installed in the computer, coupled with the corresponding driver software, can make the LED display screen synchronously play cable TV channel programs, whether it is needed, users can buy it by themselves, the price Not expensive.

 10. LED video processor: It is mainly to improve the overall display effect and functional application of the large screen, and fully tap the value of the display screen. Solve the problems of access, processing and display of various video signals, and can complete the format conversion between many signal formats. There are many brands and models of LED video processors with different prices.

 11. LED playback software: including computer system software, LED video playback software, etc. Generally provided for free

 12. Steel structure, manual installation: The bracket used to fix the display screen is generally made of steel frame structure, and aluminum-plastic plate or stainless steel edging material. Including manual installation costs (suggestion: the manufacturer can provide the steel frame structure design drawings free of charge, the customer can find the local manufacturer to make it, the production is simple, and the ordinary workers can complete it, the cost is low, and the installation is convenient)

 13. Freight: Depending on the shipping distance budget, I believe that the majority of customers can still accept. In terms of costs, customers can also be responsible for themselves, and they can report.

 14. Technician fees: When the display screen is delivered to the customer, the company will send 1-2 technical engineers to help guide the installation and technical debugging. The customer only needs to be responsible for the general room and board expenses and round-trip travel expenses of the technical engineer, and report it.
