I am interested in acquiring a stadium LED advertisement board that measures 0.9 meters in height and 1 meter in length. My intention is to enhance the visibility of advertisements during events, so I'm looking for a high-quality board that offers excellent brightness and color saturation. Additionally, I would appreciate any options regarding customization, such as different colors, resolution, and connectivity features, to accommodate various advertising needs. Could you provide me with details on available models, including pricing, minimum order quantities, and lead times for production and delivery? It would also be helpful to understand the warranty options, as well as any after-sales support that your company offers. Looking forward to your prompt response so we can discuss this in more detail.
