AT&T 소매 핵심 사업 부문을 위한 4-in-1 COB 프로토타입

Following AT&T's successful 630-unit P2.5 pillar rollout, the next question was inevitable: which pixel pitch for flagship stores? Rather than months of theoretical debate, DOIT VISION engineered a 4-in-1 prototype pillar with P1.25, P1.538, P1.86 COB, and the original P2.5 SMD all on a single unified chassis. Delivered in 14 days, AT&T decision-makers walked around the pillar comparing resolutions side by side. More importantly, 100% backward compatibility means these new COB modules are millimeter-level drop-in replacements for the existing 320x160mm chassis, future-proofing 630 deployed pillars.
