美国采购需求：500x500 LED面板，附近的LED显示屏，LED显示面板，LED移动广告车，移动LED广告牌车，P3 LED显示屏

I'm reaching out regarding a university client in New Orleans who has previously purchased a specific display system and is now looking to acquire another unit. They are interested in partnering with us as AV integrators capable of offering comprehensive service. Could you let me know if your company offers a comparable display solution to the one they previously used, particularly with battery power options? If you have any relevant models, I'd appreciate it if you could send over a brochure and pricing details. I can provide more specifics on the original system if needed. Looking forward to your response!
