Components of the cost of purchasing LED displays

????? 1. The cost of the LED display screen body: it is usually calculated according to how much per square meter, that is, the price of the common LED display screen is xxx yuan/㎡. There is a difference. The screen quotation includes LED modules, dedicated 5V constant current power supply, cable (data cable), power cable inside the screen, unit box, etc. 2. LED player software: including computer system software, LED video player software, etc. These are generally provided free of charge. 3. Control system cost: that is, the cost of the LED display sending card and receiving card. The conventional LED display (1280*768 pixels) can not use the sending card, and the number of receiving cards is N. The number of receiving cards is mainly based on the arrangement of the screen. It is determined by the number of pixels and the number of pixels. Usually, the maximum pixel carried by a receiving card cannot exceed 256*256 pixels. If the maximum pixel load is exceeded, the refresh rate of the screen body cannot reach the stroboscopic problem. If different video source signals are required, such as (camera, DVD, digital TV card, etc.), the video signal must be processed through the sending card interface, and the sending card needs to be configured. A single sending card cannot carry more than 1.2 million pixels. The number of sending cards depends on the size of the screen. Generally speaking, the larger the area and the higher the density of the display screen, the more sending cards and receiving cards are used. 4. Control computer: the necessary equipment to control the LED display, the general configuration requirements: dual-core CPU, 4G memory, independent graphics card above 1G, gigabit network port, and 2 PCI slots on the motherboard. If the pixels of the screen are very high, the configuration of the computer should be improved accordingly, and the pixels of the computer monitor should be larger than the pixels of the LED display. 5. Sound + power amplifier: LED display screen plays audio synchronously when playing video programs. Generally, it is equipped with 1 power amplifier and 2 waterproof sound columns. 6. Power distribution cabinet: Small-area LED display can be used without, and a power distribution cabinet system needs to be configured when the power is greater than 10KW. The main function is to provide a stable voltage and current power supply for the stable operation of various components of the LED display equipment, and effectively prevent the LED display power supply switch from jumping and other faults. 7. Lightning arrester: The outdoor LED display is mainly used as a lightning protection device, and the indoor LED display can be used without it. 8. Air conditioner: heat dissipation equipment, outdoor LED display screens over 20 square meters must be equipped with air conditioners to ensure the normal operation of the screen body and prolong the service life of the various components of the display screen. Generally, indoor screens or small-area display screens can be used. Large-area indoor LED display screens should be equipped with wall-mounted air conditioners to effectively cool down, ensure the normal operation of the display screen at high temperatures, reduce failure rates, and increase life expectancy. 9. Video capture card: Commonly known as TV card, it is installed in the computer and equipped with the corresponding driver, which can make the LED display screen play cable TV channel programs synchronously. Whether it is needed or not, customers can choose it by themselves, and the price is not expensive. 10. Video processor: mainly to improve the overall display effect and functional application of the LED screen, and fully tap the value of the display screen. Solve the problems of various video signal access, processing and display, and can complete the format conversion between many signal formats. There are many brands and models of LED video processors with different prices. 11. Steel structure: The bracket used to fix and install the LED display. The steel structure is different in different environments. Usually, it is wall-mounted, column-mounted, hoisted, and inlaid. It is specially designed for special occasions. It is recommended that customers take pictures of the installation environment Give us, Shenzhen Lianhuiye Technology will design for you for free. Usually, we provide CAD steel structure drawings for free, Party A buys materials locally and finds someone to weld, so the cost will be slightly lower. If you entrust us to make it, there will be expenses for round-trip transportation, board and lodging. 12. Freight: Different regions will have different charges, such as provincial capital cities or regions, and county-level cities. Firstly, distance is the main factor, and secondly, whether transit is required. I believe that customers can still accept it. 13. Technician fee: when the LED display is delivered, the company will send 1-2 technical engineers to assist in the installation, commissioning and training. The cost includes personnel costs + transportation + board and lodging. Usually the quotation does not include tax. Shenzhen United Huiye Technology is a general taxpayer. If the customer specifies that tax is included, we can issue a 17% value-added tax invoice, and the corresponding tax point needs to be added. The above is about the various expenses included in the quotation of the LED display screen, which is convenient for customers and friends to have a clear understanding, so that they can have a bottom of mind when purchasing. .
