The price of led display is too complicated and cumbersome for people outside the industry, and even more than half of the people in the industry are in a state of confusion. The complete production and assembly industry chain of led display is very large and complex, which affects the led display (http://www.khytech.com)’price. The price is summed up as the following 5 points, which are all from the technical level to make an analysis.
The first factor that affects the price of LED displays is the production process of the product. The details in the production process determine the display effect, lifespan and oxidation resistance of the led display, produced by inferior three-proof processing technology. The anti-fatigue performance of the module is difficult to guarantee. When the temperature and humidity change, cracks will appear on the protective surface of the circuit board, resulting in a decrease in the protective performance. Therefore, the production process of the LED display is also a key factor in determining the life of the LED display.
The production processes involved in the production of led display screens include: component storage and pretreatment process, furnace welding process, three-proof treatment process, waterproof sealing process, etc. The effectiveness of the process is related to material selection and ratio, parameter control and the quality of the operators. For most LED display manufacturers, the accumulation of experience is very important. A factory with many years of experience will be more effective in controlling the production process. As a result, the price of peer-to-peer led display screens has also increased, driven by the costs of manpower, technology, and equipment.
The LED display is composed of countless LED light-emitting chips (light-emitting diodes) components. The LED chip is the most critical and most relevant component of the LED display. For the LED chip, its indicators are mainly: attenuation characteristics, waterproof vapor Penetration characteristics, anti-ultraviolet properties. If the LED display manufacturer fails to evaluate the performance of the LED chip, when it applies to the LED display, which will cause a large number of quality accidents and seriously affect the life of the LED display. At present, the LED chip can be produced domestically and internationally. There are actually so many manufacturers, but the price gap is very large. There is a difference of close to 10 times between the end and the international first-line price. The LED light-emitting chip used greatly affects the price of the LED display.
In addition to the above-mentioned production process and the impact of LED chips, the impact of LED display components cannot be ignored. The entire appearance of the screen that attracts attention in the LED display project is the first to bear the brunt, but the LED display It contains many supporting parts, such as PC circuit boards, cabinets, wires, power supplies, many plug-ins, heat dissipation, external installation of the screen, and so on. Many of these parts may cause the LED display to display effects if there are quality problems. And the reduction in service life, it can be seen from here that the price of the led display is affected by the supporting parts.
For example, the power supply and metal casing standards must be selected according to the 8-year standard, and the protective process performance of the PC circuit board can only support its work for 3 years. After 3 years, it will be damaged due to corrosion, so we can only get a 3-year lifespan. LED display screens, and led display the price of supporting parts is also different, which affects the price of LED display screens.
There are many types of led display screens, and they are mainly divided according to the use environment, such as indoor, outdoor, conference room, building, monitoring room, etc. The supporting components and production processes corresponding to different use environments will be different. What kind of led display to purchase, then let it be used in a suitable environment.
From the analysis of the use environment of the led display screen, the indoor temperature difference is small, there is no wind, sun, rain, or strong ultraviolet radiation; and the highest temperature in the outdoor environment is 70 ° high temperature, plus various harsh conditions. Different product standards are affected by the weather.
It is usually said that the service life of the LED display screen is 100,000 hours, but this is based on a standardized use environment, and in fact it is difficult to achieve this ideal use environment.
The reason why the use environment affects the price of the led display is because of communication, and different use environments correspond to different standards. Unlike small commodities in life, you can without communicate and purchase casually. The more detailed the communication, the closer the price of the led display is to the truth, which may be with customers’s psychological expectations will be biased, but this is the true price.
It is normal for a led display project to take 6 months from project establishment to landing. It requires professionals to connect with customers, free preliminary detailed communication, on-site environmental survey, program design, and provide customers with plane renderings, design renderings, and so on.
Every led display project needs to be tracked by a dedicated person throughout the whole process, logistics packaging, check and inspection of supporting parts, remind customers of the matters that should be prepared, ignoring any of them may cause delays in half a month, and the details of these services are all there are many real cases, because the negligence of the packaging caused the product to be damaged, and the product was sent back for redo; the kit was wrong, the specifications were different, the lack of this and that was delayed; the customer forgot to wire, the site was not prepared, the procedures were incomplete, and so on.
The operation and use of the led display requires professional personnel for pre-training, user manual, software operation, etc., common problem response, long-term technical guidance and after-sales service, no manufacturer can guarantee that the led display will not have any problems, regular maintenance After-sales service and after-sales service is a very important part, and the travel expenses and labor expenses can easily be tens of thousands.
For example, a regular return visit once every three months, maintenance and inspection of the overall equipment, software, and system of the led display screen, troubleshooting possible safety hazards, and ensuring the long-term use of the led display screen, but not just looking for someone can do it by dispatched technicians , Need to have a high level of technology and quality, to be able to help and assist customers in solving problems, and to help customers practically.
The fifth point of service is a factor that has the highest rate of neglect by customers and even industry insiders, which affects the price of LED display. Service is something invisible and intangible. It is very virtual but must exist. It is necessary to ensure the effect and life of the LED display. and the service is based on a reasonable profit.
