And our PMC will offer you the right time before you placing the order. Then we will arrange the shipment to your sea port.Higher brightness than LCD display. Easy to show the content to others in door. Especially the bright condition in door. With 10 engineers, 26 worker, 8QC and 6000m2 factory, we can meet most all the customers requirement. These are not the key factors. The 6LED SMT automatic production lines is important. The most important factor is the supply chain.Generally speaking, the led beads cost of the LED display is about 30%. With this rate, the warranty can be 1 year. Under this rate, the warranty must be under one year. Our rate is 52.6%, our warranty is 3 years.Power is also very important, but you can maintain them with good temperature and good condition. The life will be lengthened. The same with display card.For each customer, we offer each solution, including the delivery time. And offer the manual of installation stpes based on your condition. With drawing picture. And also with maintain ways, remarks.Q: It is so far, we worry about the quality warranty.A: We sign contract with you and prepare standard spare parts for you in the thress years in case.Q: We worry about cheap products with expensive price.A: Our reputation is more expensive. We choose good material with our technology, becase we want to save aftersales cost. And it also our cheap advertisement.Q: How can pay the money?A: Sign contract first with company print, TT transfer 30% before production and 70% before shipping. Our sales with take pictures for your conformation.Q: Some of the LED display problem is caused by our mistake. What can we do?A: Firstly, we have some measure to stop your some mistake. Second, if there is real any problem,we will offer you the solution and the right material with cost price. Our requirement is quick and right. Because the time is the most expensive cost. Our reputation is the most important factor!For the LED display screen, most people think that the main material of the screen, LED and IC, has a life of 100,000 hours, running in 365 days/year, 24 hours/day, and has a life span of more than 11 years, so most customers only care about using well-known LED and IC. In fact, these two are only necessary conditions, not sufficient conditions, because the rational use of red, green and blue light tubes is more important to the display screen. For different color light tubes, in order to make them work in the best state, it will be more important for a good display screen. Reasonable adjustment of IC also helps to overcome the unreasonable wiring problem of PCB.The key factors are as followsBecause LED and IC belong to semiconductor devices, they are critical of the environmental conditions, preferably at room temperature about 25 C, and their working mechanism is the best. But in fact, a large outdoor screen will be used in different temperature environments. In summer, it may be above 60 C, and in winter, it may be below - 20 C. When a manufacturer manufactures a product under the test condition of 25 degrees Celsius, classifies different products into different grades, but the actual operation condition is 60 degrees Celsius or - 20 degrees Celsius. Then the efficiency and performance of LED and IC are not consistent. It may be that the original one-grade products will become multi-grade ones, the brightness will not be the same, and the screen will naturally become more expensive. This is because under different temperature conditions, the attenuation and decline of the brightness of red, green and blue lamps are different. At 25 C, the white balance is normal, but at 60 C, the brightness of the three colors of LED decreases, and their attenuation values are inconsistent, so the whole screen brightness decreases and deviates.
