How to find a good LCD n manufacturing supplier in China?

Many foreign customers may have a problem in finding a good LCD manufacturing supplier in China. Based on my working experience with global customers over the years, I would like to share some ideas.

Before placing an order, how to evaluate whether the LCD manufacturer is suitable for you?

First of all, it would be great if you could go to the factory for visit. You can see the equipment and its product technology with your own eyes. You can have more time to talk with more people to better understand their communication and technical knowledge. However, not everyone likes to travel far away, especially in the case of the novel coronavirus pandemic. In this case, you need to check carefully whether their daily communication response is timely through e-mail / telephone; Whether they can answer your questions fully or whether they always need you to ask more questions through email. You also need to check whether their prices are good and stable by asking 3 to 5 quotations. Second, you can choose a possible small project and need a free DFM to check their basic design skills. Last but not least, you need to check that your potential suppliers are complying with their commitments. For example, they said they would reply to your quotation within 2 hours, but they didn't reply in time and didn't inform you the reason in advance. Then, I think they may not be the supplier of on-time delivery. In Chenghao LCD company, we have more than 7 years of global customer working experience, some of which have opened up more and more markets after cooperating with us. Our timely service and response make them feel safe for any project. We are not the best supplier, but our quality is good enough for them. The most important thing is that we abide by our commitments and never make excuses when there are problems. Although more than 99% of the problems are small problems that rarely occur, after inspection, we have assumed corresponding responsibilities and given urgent and permanent solutions.

After placing a trial order, the inspection of the new supplier has not been completed. How to continue the inspection?

After you place a small trial order with a new LCD manufacturing supplier, you have more ways to check them. First of all, drawing design is a very important and key start before LCD manufacturing. During the discussion and exchange, you can check their development experience and process manufacturing skills.

Secondly, in the LCD manufacturing process, you can check whether they respond to your problems and requirements in time. Whether the sales staff and engineers can work closely to make your project goes smoothly. For samples, a sample inspection report must be provided so that you can check the dimensions. Samples will be sent to you by courier for inspection. In the process, you will see our capabilities. Most of our customers are very satisfied with our samples.

Third, when you customize the LCD screen. If you need to correct or modify the process, you can check the supplier's communication skills and response time. At the same time, you can see how quickly the supplier completes the modification and how high the modification cost is due to your part change. Some companies have a long transformation cycle and high transformation cost. After the first small order, you will know the modification lead time and cost level of the supplier.

Finally, your customized samples are very important. Some companies like to promote new products or relevant technical materials on the Internet. If you agree, I don't think it is suitable to display new customized LCD drawings and technical related materials. In Chenghao optoelectronics team, we are not allowed to display problems such as module pictures, new drawings or related technical information. It is our responsibility to keep your new products confidential.

For a customized LCD project, all the above contents are very important. Suppliers and customers are business partners and friends. We always pursue win-win. The success of customers is the success of suppliers!
