Analysis of LED Screen Price Components

Analysis of the price components of LED screens, LED screens have now become a popular product in advertising communication, and there are good solutions for both indoors and outdoors. Indoor LED screens do not have such high requirements for the environment. Due to the influence of temperature, illuminance, and ultraviolet rays, outdoor LED screens have higher requirements than LED screens for brightness, protection performance, and UV-resistant materials. We often meet many friends who are interested in buying LED screens. As for how to choose an LED screen, which parts are included in the cost, and which parts are not required, we will help you reasonably plan the functional requirements of LED screens based on years of experience in LED screens, so that You have an intuitive concept.

1. The cost of the LED screen body: it is generally calculated according to how much per square meter, that is, the price of the common LED screen is xxx yuan/m2, and the screen spacing and materials used are different, and the quotation will also be different. The screen quotation includes a full set of LED screen requirements: LED lamp beads, circuit boards, driver IC chips, dedicated power supplies, steel cabinets and plastic masks, bottom shells, and all signal lines and power lines inside the screen, etc. Whether the quotation on the whole screen includes tax may be different, please ask clearly when consulting.

2. Video processor: Due to the high pixels and many input devices of the current LED screen, it is necessary to use a video processor to switch different video source signals, such as high-definition TV, video camera, computer, U disk, etc. Some video sources, in addition The dedicated LED screen video processor can split multiple screens, image optimization processing and so on. If the pixels of the LED screen are very high, beyond the control range of the computer, then the cascade control of the video splicer must be used. There are many brands and models of LED video processors with different prices.

3. Control system cost: that is, the cost of the sending card and receiving card of the LED screen. Generally, a small screen only needs 1 sending card (within 1.3 million pixels), and a single sending card has 1.3 million pixels. For cascading control, the LED sending card can be installed in the host computer or in a dedicated video processor. The number of sending cards must be matched according to the arrangement of the screen. The number of pixels loaded by a single receiving card cannot exceed 256* 256 pixels, small pitch Due to different scanning methods, the loading range should be reduced. The use of control cards is mainly determined according to the size of the LED screen. Generally speaking, the larger the area and the higher the density of the LED screen, the more sending cards and receiving cards are used. 4. Control computer: The necessary equipment to control the LED screen requires configuration requirements or higher: dual-core CPU, 2G memory, DVI graphics card, and a PCI-E slot for the motherboard.

5. Power distribution cabinet: Small-area LED screens can be used without. LED screens with a power of more than 10KW must be equipped with a special power distribution system for LED screens, which can provide stable voltage and current for the stable operation of LED screen equipment and devices, and provide a guarantee for the safe operation of LED screens. Strong guarantee. In addition, the current intelligent distribution box system can remotely operate timing switch, real-time startup and shutdown, smoke monitoring, temperature monitoring, automatic brightness adjustment and other practical functions. 6. Sound + power amplifier: The device that allows the LED screen to synchronously play video to produce sound, generally equipped with 1 power amplifier and 2 speakers.

7. Air conditioner: heat dissipation equipment, outdoor LED screens over 20 square meters must be equipped with air conditioners to ensure the normal operation of the LED screen and prolong the service life of the screen components. Generally, indoor screens or small-area screens can not be used. Large-area LED screens are strongly recommended to be equipped with air conditioners to effectively cool down, ensure the screen can travel normally under high temperature, and reduce the failure rate. 8. Lightning arrester: used for outdoor LED screens, mainly as lightning protection devices; indoor screens may not be used.

9. Multi-function card: The main function is to intelligently adjust the brightness, temperature and other values ​​of the LED full-color screen in different periods of time, so as to achieve energy saving and prolong the service life of the LED screen. 10. LED player software: including computer system software, LED video player software, etc. These are generally provided free of charge.

11. Video capture card: TV card, a small card, installed in the computer, with the corresponding driver software, can make the screen play cable TV channel programs synchronously, users can buy it by themselves if they need it, and the price is not expensive . 12. Steel structure, manual installation: The bracket used to fix and install the LED screen is generally a steel frame structure, and there are also aluminum-plastic panels or stainless steel edging materials. Including manual installation costs (suggestion: the manufacturer can provide free steel frame structure design drawings, the customer can find a local manufacturer to make it, the production is simple, ordinary workers can complete it, the cost is low, and it is convenient to install) 13. Technician fee: LED screen hair After delivery, the company can send 1-2 technical engineers to assist in guiding installation and technical debugging.

The customer only needs to be responsible for the general board and lodging expenses, round-trip travel expenses and workers' wage costs of our technical engineers, and the actual report is sufficient. 14. Freight: It depends on the delivery distance. I believe that the majority of customers can still accept it. Usually, the delivery method is precise logistics transportation, and the fee is paid on delivery. The above is the place where the quotation of the LED screen includes various required expenses, so that friends in need can have a clear understanding, so that they can have a bottom of mind when purchasing.
