阿拉伯联合酋长国采购需求：室内固定式LED显示屏

I'm looking to source LED panel screens that fit a 4x4 metre square setup. Please provide details on your available options, including specifications, features, and any customization possibilities. It's also important to know the pricing structure, especially for bulk orders, as well as lead times for production and delivery. Additionally, I'd appreciate information on warranty terms and your after-sales support services. Any insights into previous projects or client testimonials related to similar products would be helpful to gauge the quality and reliability of your panels. Looking forward to your prompt response with this info!
