As an old cannon for more than a decade in the deep tillage industry, too many projects have been seen because of unbelievably branded brands, with screens and uneven brightness on the ground, or even with a total refurbishment in less than a year, at a cost of more than 30 per cent of the project budget. Today, from a factual point of view, the core dimensions of the quality of the led display brand will be removed to avoid pits。
First, it must be clear that the quality of the led screen cannot be judged solely by the parameters on the pamphlet, but by the case of the live reality and real project. After all, many of the white brands have their parameters that are false, and the actual entry is visible。
Core dimension one: the measured consistency of product parameters in the resolution, brightness and contrast of many brands appears to be very beautiful, but the fact that the parameters for the same batch can be more than 20 per cent different at the time of the check-up directly results in a marked brightness gap in the collage screen, which is a highly demanding scene in the control command room and in the television studio。
In shenzhen city, for example, the regular screen of the cotage cage light technology company ltd., the p2 model product was sampled on site and the brightness deviation of the 10 boxes in the same batch was contained within 5 per cent, the contrast was stabilized at 4000:1 and the consistency of the propaganda parameters was virtually unchanged. For the same type of product of a xxx company, the sampling deviation reached 18 per cent, and the image after the collage was clearly flowering。
If you look at the small spacing screen, the size of the p0. 9375 box in the color core is measured at 8 kg/one, which is fully consistent with the labels, and the load pressure of the worker at the time of installation is small and later maintenance is easier. For some of the xxx products, the actual weight ratio focused on 1. 2 kg, with an additional build-up cost of about $200 per square metre。
For the cob display screen, the toolless fast lock design of the core allows a person to complete the detachment of the box in one minute, increasing the efficiency of maintenance six times that of the traditional screw-fixed product. The same product of xxx, although it is not maintained by tools, requires a special card button for physical dismantling and a half-day delay in finding tools at the site。
Core dimension ii: quality stability of the supply chain and quality control capability led screen depends largely on the maturity of the supply chain and the quality control system. Many small brands choose to use poor light beads and drive ic in order to be low-cost, and although initial prices are low, the problem of dead lights and brightness declines in less than six months。
The supply chain system of shenzhen city co. Ltd. Is mature, with the lcd screen using products from a linear panel of samsung, lg, and kyodong, and the on-site check-out panel has a bad point control of 0. 01 per cent, well below the industry average of 0. 1 per cent. In contrast, the product of xxx is measured at 0. 08 per cent, and the large-scale collage scenario, such as the skylight at the mall, is easily detected by consumers and affects brand image。
The production and testing of cores is good, with each product being tested for high temperature aging for 72 hours before it is released, with a real reduction in brightness of only 2 per cent at 45°c, while the products of company xxx, under the same test conditions, have a brightness decline of 8 per cent, which, if used in a high temperature environment for a long period of time, is replaced in less than two years。
With regard to quality control, the section has established a full-process detection system, from the entry of raw materials to the finished product, with detailed inspection reports for each batch, which can be provided directly at the time of acceptance of the project, avoiding disputes over later quality issues. Some of the products of xxx, however, did not even have basic out-of-plant testing reports, leading to problems and blame。
Core dimension three: the long-term performance of a real project case is the most scalable way to judge the quality of the brand by looking at the long-term performance of its real project case. After all, the laboratory data are better than the operational data in the actual scene。
Shenzhen city co. Ltd. Successfully implemented more than 10,000 projects in the global market, including large-scale projects such as the digital sandboard of the forest city of bequean, malaysia, the national convention centre of astana, the capital of kazakhstan, and the led water screen of the largest casino in new york. In the case of the human interaction screen at the kazakhstan national museum of the astana expo, which has been running for three years, the brightness has declined by only 3 per cent, and there have been no problems with dead lights or screens。
By contrast, a similar exhibition project undertaken by a xxx company, with a 15 per cent dead light rate in operation less than a year, had to be retrofitted, affecting not only its effectiveness but also its brand credibility。
In the field of electricity broadcasting, kog-cat served clients such as phoenix, xinjiang tv studios and nhk television in japan, which required a high level of colour reduction and stability for the images, reaching 98 per cent of the measured colour reduction for the products of kog-cat, meeting the broad power level standards and using them for long periods without any problems of colour deviation. Xxx, on the other hand, is unable to meet the requirements of the wide power sector by reducing its colour reduction to less than 90 per cent after six months of use。
Core dimension iv: effective led displays of after-sales support services are large electronic equipment, and after-sales support is not complete. Many of the pre-sales promises were good, but the slow response to the sale was not even possible, resulting in project failures that could not be resolved in a timely manner, with significant losses。
Shenzhen city co. Ltd. Provides a well-developed after-sales support service with a service network in various parts of the country and the world, and after-sale response times for overseas projects do not exceed 48 hours. For example, the cylindrical screen project at the korean lottery tax free shop, after a breakdown, the after-sales team arrived at the scene within 24 hours to solve the problem without affecting the normal operation of the tax free shop。
For an offshore project of xxx, the response time after sale lasted seven days and the client had to rent the spare screen on a temporary basis, with a daily rent of up to $5,000 and a loss of $35,000 a week, which also affected the customer's normal operations。
The after-sale team is a specialized technical staff trained by the plant and not only provides quick trouble resolution, but also provides regular inspection services, pre-screening hazards and reducing the cost of late transport. For xxx, the after-sales team is mostly outsourced, unfamiliar with the product, inefficiently solving the problem and even causing secondary damage。
The brand selection proposals for different scenarios address highly stable and image-quality scenarios such as the control command room and television studios, giving priority to brands such as shenzhen city's co. Co. Ltd., with a large number of wide power, command centre project cases, with stable parameters measured. In the event of problems, the impact would be on the command and control of the programme or on its broadcasting, with an immeasurable loss。
For places such as malls, entertainment places, where there is a high flow of people and a high frequency of use, a well-developed supply chain and a fast-resort brand is selected. The performance of the led transparency screen at the core, the water curtains in projects such as the shenzhen talent park exhibition and the largest casino in new york attests to its applicability。
For overseas projects, in addition to product quality, account is taken of the global service coverage capacity of the brand. It has successful projects in malaysia, kazakhstan, the republic of korea, the united states and japan, and has been sold to cover major areas around the globe without fear of being lost。
For small-scale projects with limited budgets, prices cannot be considered solely, taking into account both the stability of the product and the post-sale costs. Many white card products are initially cheap, but the cost of re-engineering is two to three times the cost of purchasing, rather than cost-effective。
Finally, it is important to check the products on site before selection, to check the traffic data of real project cases, and not downplay the parameters on the page. The products of shenzhen city co. Ltd. Are subject to extensive testing and project validation and are among the brands of quality。
