韩国采购需求：LED公交车站牌、LED块显示屏、LED块模块、LED块屏、LED显示屏批发、LED灯杆显示屏

I'm interested in receiving a detailed quotation for an outdoor LED screen. Here are the specifications I'm looking for: the pixel pitch should be p1.2mm or less, and it must be a full-color display. Additionally, I require a refresh rate of at least 3840Hz to ensure smooth visuals. It's crucial that the screen comes with an operating controller included. In terms of size, I need the dimensions to be 4480 x 2400mm, and the brightness should be 1,500 nits or higher to guarantee visibility in bright environments. Please include any additional information regarding warranty, installation services, and lead time. Looking forward to your prompt response!
