美国采购需求：55 英寸触摸膜，高灵敏度触摸膜，交互式显示膜，多点触摸屏，USB 10 点，PCAP 触摸膜

I am interested in obtaining pricing information for a specific model of a 50-inch capacitive touch panel screen. It should feature a nano pcap touch film and offer USB connectivity. Additionally, I require that it supports true multi-touch with at least 10 simultaneous touch points. Moreover, the touch panel must be vandal-proof and waterproof, making it suitable for outdoor applications. Specifications regarding durability, performance under various environmental conditions, and any available certifications would be greatly appreciated. Please provide your best pricing and available quantities for this product, as well as estimated lead times for delivery.
