商场正立广告屏样机绿幕显示画面图片

Generate an image: A tall, freestanding LED advertising screen at the entrance of a high-end shopping mall. The screen displays a solid, pure green color with no shadows, making it easy to remove the background and replace the content later. The image features a marble floor with a metal-framed structure, creating a minimalist and modern commercial space atmosphere. The main subject is centered and occupies approximately three-quarters of the frame, ensuring it is fully visible. The aspect ratio is 16:9, and the style is realistic commercial space photography.
