In terms of color, LED advertising displays can be divided into single-color, two-color, and full-color LED displays. From the use environment, they can be divided into indoor, outdoor, and semi-outdoor. The price of LED screens of each specification is different. Indoor full color is divided into surface mount full color, surface mount three-in-one full color, dot matrix full color, outdoor full color is divided into 1R1G1B (generally high density, such as: PH10, PH12), 2R1G1B (generally high density , Such as PH16, PH20, etc.). In order to reduce costs, many manufacturers will use a bright red light to match colors!

Materials have a great impact on the price of LED displays:
In terms of materials, it can be divided into imported materials and domestic materials. In terms of light-emitting chips, the sources of imports are: the United States, Japan, Taiwan, and there are also some domestically-made chips. Each light-emitting chip has its own advantages and disadvantages. American and Japanese chips, because they have always mastered the core technology, under the background of similar monopolies, the prices of American and Japanese chips remain high. Chip prices in Taiwan and the mainland are relatively cheap, but there is still a certain gap in performance compared to chips from the United States and Japan. If the LED advertising display is used in more important occasions, we still recommend using imported materials; in addition to the LED chip, the main factor affecting the price of the LED advertising display is the LED driver IC, but if I am a customer, I would rather Choose a better driver IC, because although it is a bit more expensive, the driver IC is a very important factor affecting the quality and life of the LES display. When making a full-color LED advertising display, you must use a constant voltage and constant current driver IC ; Other materials such as power supply, cabinet, and various accessories for making display screens.

①System accessories: sending card, receiving card, transfer card;

②Playing system: controlling computer, multimedia card or graphics card, playing software;

③Editing system: editing computer, video compression card, editing software;

④ Monitoring system: sensor + monitoring software;

⑤Protection system: heat dissipation system, power distribution system, lightning protection system, temperature and humidity monitoring system;

⑥Sound system: amplifier + speaker;

⑦Video input equipment: DVD/VCD player, video recorder, closed-circuit television;

⑧ Graphic input: scanner, digital camera.

The above accessories and equipment are optional except system accessories and playback system. Due to the influence of brand and purchasing channel, the price of LED advertising display screen is naturally different.
1. Display screen 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 price will be different if the display model and materials are different. The screen quotation generally includes a full set of LED color screen requirements: die, module circuit board, IC driver chip, module power supply, steel box and plastic mask, and all cables and connecting wires inside the display. Generally, the price includes tax.

The slickness in the quotation of the screen body is the biggest. You can't just ask how much the P is. The selection of craftsmanship and materials also have an important impact on the quotation. These terms and requirements must be clearly agreed in the contract.

2. Control system cost:

That is, the cost of the sending card and receiving card of the display screen. Generally, one screen only needs 1 to 2 sending cards, which are installed in the host computer and the number of receiving cards is n. The use of control cards is mainly based on the size of the display screen to determine the number. Generally speaking, the larger the area and the higher the pixel density of the display screen, the greater the number of receiving cards used.

That is, the maximum loading capacity of each receiving card, the specific loading capacity of each receiving card is different, and the length and width of the LED display screen with different receiving cards are different (length and width refer to It is the pixel), this is based on the design of the receiving card, the pixel of the receiving card must be larger than the pixel of the screen, so that it can be carried.

3. Control the computer:

The necessary equipment to control the LED display requires higher or higher configuration requirements, an independent graphics card, and a PCI slot on the motherboard.

4. Audio + power amplifier:

A device that allows the display to synchronize video playback with sound is generally equipped with 1 power amplifier and 2 speakers.

5. Power distribution cabinet:

Small-area LED display screens are not necessary; it is recommended that the maximum power consumption is above 10KW for display devices, which can provide voltage power and current for the stable operation of various devices of the display device, and effectively prevent failures such as the power supply switch of the display screen and other failures.

6. Air conditioning:

Heat dissipation equipment, general indoor screens or small-area displays can not be used, but it is strongly recommended that large-area indoor displays be equipped with wall-mounted air conditioners to effectively cool down, ensure that the display screen can travel normally at high temperatures and reduce the failure rate. Outdoor LED displays of more than 20 square meters must be equipped with air conditioners by the manufacturer to ensure the normal operation of the display and prolong the service life of the components of the display.

7. Multifunction card:

For indoor display, the main function is to intelligently adjust the brightness and temperature of the LED full-color display in a period of time, intelligently adjust to achieve energy saving and power saving, and extend the life of the LED display; the indoor display can not be used.

8. Lightning arrester:

Outdoor LED display is mainly used as lightning protection device; indoor display can not be used.

9. Video capture card:

The TV card, a small card, is installed in the computer and equipped with the corresponding driver software, which can allow the display to play cable TV channels simultaneously. Users can buy and choose by themselves, and the price is not expensive.

10. LED video processor:

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 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.

11. LED playback software:

Including computer system software, LED video playback software, etc. They are generally provided free of charge.

12. Steel structure, concrete foundation, labor costs:

The bracket used to fix and install the display screen generally uses a steel frame structure, and there are aluminum-plastic panels or stainless steel edging materials. The outdoor LED screen can be fixed on the concrete base. There are also manual installation costs (recommendation: the steel frame structure design drawings can be provided by the manufacturer for free, and the customer can find the manufacturer in the local area to make it. The production is simple and can be completed by ordinary workers. The cost is low and the installation is convenient. The premise is that you can control the construction. quality).

LED display screens are affected by factors such as installation location, installation method, screen size, frame structure material selection, etc. The price of installation projects will definitely vary greatly, especially when installing outdoor full-color LED display screens. Environmental impact, project prices vary greatly.

The design of the steel structure and the concrete foundation is very important. The strength must meet the load-bearing requirements. It is not uncommon for LED screens to fall and collapse due to insufficient strength. The person responsible for the accident is legally responsible!

13. Freight:

Depending on the transportation 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.

14. Technical staff cost:

When the display screen is shipped to the customer, the company sends 1-2 technical engineers to assist in the installation and technical debugging.

15. Other:

The payment method, tax rate, transportation method, and the manufacturer's own factors all determine the price of the LED advertising display.
