电脑展・巨型主墙：LED影像作为背景

Design a technology trade show booth anchored by an enormous seamless LED wall. Build a curved LED screen about 16 metres wide and 5 metres tall as the back wall of the stand, its panels perfectly aligned with no visible seams, displaying slow abstract motion graphics in cool blues and whites that light the whole booth. Keep everything in front of it deliberately dark and low so the screen dominates: black plinths at waist height carrying products, a low black counter, and dark carpet. Place a small presentation stage in front of the screen with a slim lectern and a ring of standing space marked by a change in floor material. Detail the screen's edge as a clean shadow gap with no frame. Add slim black uplights washing the side walls faintly. Keep the brand identity confined to the screen content itself with no applied logos. Show a crowd gathered watching the screen, their faces lit by it. Photorealistic, immersive and cinematic, eye-level view from the aisle toward the screen.
