Sometimes, clients have very limited budgets. However, thorough communication is indeed an effective way to reduce costs. For our client in the Democratic Republic of Congo, we recommended a cost-effective solution: the standard rear-maintenance P3.9 LED display. This option fully met the client's needs, allowing countries and clients with tighter budgets to safely and stably use LED displays. Of course, we were transparent with the client about the limitations of the standard cost-effective P3.9 model. Since extreme demands for image quality and impact resistance were not critical for this fixed indoor installation, our P3.9 solution was priced at a level that pleasantly surprised the client. This pricing was based on a deep understanding of the supply chain and a scientific assessment of the usage environment, rather than simply offering a low-price promotion. Being able to provide LED display solutions and products for clients with diverse needs brings us great satisfaction.
