For many non-professional friends who buy LED displays, they often feel at a loss when they face different LED display companies. The LED display price plan product composition will definitely be required as a reference, and whether the budget is overrun. Based on years of experience, the following is a detailed introduction to the various costs included in the LED display quotation, to help you have an intuitive and clear understanding when purchasing LED color screens.
1, screen body cost
The LED display panel is composed of a display module, a power supply, a box body, and a cable power line. Among them, the module has the highest cost, and the price difference between the lamp bead and the chip used is also large. Usually the screen price accounts for more than 70% of the overall price.
Note: Display screen body cost: Generally, it is calculated according to the amount of money per square meter, that is, the common LED display price is xxx yuan/m2, and the display model and materials used are different, and the quotation will be different. The screen quotation includes a full set of LED color screens: die, module circuit board, IC driver chip, module power supply, steel box and plastic mask, and all the cables and connecting lines inside the display. Generally, it is a tax-included quotation. This may be different. Please ask when you are in the specific consultation.
2, control system
LED full-color display usually adopts synchronous display system, which consists of sending card and receiving card. The outdoor display area is below 80 square meters and usually uses one sending card and 40-50 receiving cards (two boxes and one card). Indoor LED full color screens are more expensive due to higher pixel density.
Note: That is, the cost of sending and receiving cards on the display screen, generally only one sending card is required for one screen, and it is installed in the host computer, and the number of sending cards is n. The use of the control card is mainly based on the size of the display to determine the number. Generally speaking, the larger the area and the higher the density of the display screen, the more the number of receiving cards used.
3, accessories
The electronic display should work normally, and also need many accessories, such as computer (desktop computer), air conditioner (heat dissipation), lightning arrester, power distribution cabinet, audio amplifier (optional), TV card (optional), multi-function card (automatic Adjust the physical data such as display temperature, brightness, humidity, etc.), video processor (optional), etc. The spreads of accessories of different brands are very large, and customers can also purchase them locally.
Note: Control computer: necessary equipment to control LED display, need configuration requirements or higher: dual-core CPU, 2G memory, 512M or more discrete graphics, motherboard must have PCI slot.
Audio + Amplifier: A device that allows the display to synchronize the sound of video playback. It is usually equipped with 1 amplifier and 2 speakers.
Power distribution cabinet: small-area LED display can be used; it is recommended that the maximum power consumption is above 10KW power display, which can provide stable voltage supply current for each device of display device, effectively preventing the display power supply from switching. malfunction.
Air conditioning: heat dissipation equipment, outdoor LED display above 20m2 must be configured by the manufacturer air conditioning to ensure the normal operation of the screen and extend the life of the display devices. Generally, the indoor screen or small-area display can be used; the large-area indoor display is strongly recommended to be equipped with a wall-mounted air conditioner to effectively cool down, ensure the normal travel of the display at high temperatures, and reduce the failure rate.
Multi-function card: used for indoor display, the main function is to adjust the brightness and temperature of the full-color display of the LED full-color display in different time periods. The intelligent adjustment can save energy and save the life of the led display; the indoor display can be used.
Lightning arrester: for outdoor LED display, mainly for lightning protection; indoor display can be used.
Video capture card: TV card, a small card, installed in the computer, with the corresponding driver software, you can let the display screen synchronously play cable TV channels, whether you need to use, households can buy their own, the price is not expensive.
LED video processor: mainly to improve the overall display effect and function of the large screen, fully exploit the value of the display. Solve the problem of various video signal access, processing and display, and can complete the format conversion problem between many signal formats. There are many brands and models of LED video processors with different prices.
LED player software: including computer system software, LED video player software, etc. Usually available for free.
4, steel frame structure
The LED display needs to be fixed by a steel structure. Especially for large outdoor LED advertising displays, the requirements for steel structures are very high. The cost of the steel frame structure is second only to the screen body. Ordinary outdoor wall-mounted steel structure manufacturers custom-made price between 1200-1500 yuan / square meter, indoor wall-mounted LED screen square-pass structure cost of 600 yuan / square meter, Optimus column fixed steel structure, column base cost 2000-2500 Yuan / square meter.
Note: Steel structure, manual installation: bracket for fixing the display screen, generally with steel frame structure, aluminum-plastic plate or stainless steel edging material. Including manual installation costs (recommended: the steel frame structure design drawings can be provided free of charge by the manufacturer, the customer can find the producers in the local area, the production is simple, the average worker can complete, the cost is small, and the installation is convenient)
5, logistics, installation, etc.
The last is transportation and installation costs.
Note: Shipping: Depending on the shipping distance budget, I believe it is generally acceptable. You can also be responsible for the expenses, and you can report it.
Technician Cost: At the same time that the display is delivered to the customer side, the supplier sends 1-2 technical engineers to assist in the installation and technical debugging. The customer only needs to be responsible for the general board and lodging expenses and round-trip tolls of the supplier technical engineer.
With this basic knowledge in mind, users may wish to have a clear quotation in the face of different vendors, lest some vendors reduce prices by reducing or reducing the configuration.
