Digital advertising has evolved from bulky screens to ultra-slim, high-impact displays. The Riotouch LED Poster Display (70″ and 83″) represents the latest generation of vertical advertising screens — a seamless, borderless LED canvas designed for retail stores, corporate lobbies, airports, banks, and every modern commercial environment.
With COB (Chip-on-Board) packaging, a stunning 5000:1 contrast ratio, and ultra-low power consumption, the LED Poster delivers vibrant visuals that capture attention while keeping operating costs minimal.
Chip-on-Board (COB) technology replaces fragile SMD screens with a durable, anti-collision panel. Instead of thousands of exposed LED beads, COB encapsulates the chips directly on the board:
In a busy storefront where people brush past the screen, COB means the display keeps looking perfect — day after day.
The 3840Hz refresh rate eliminates screen flicker completely:
Whether your content is a scrolling product promotion or a live event feed, the LED Poster renders it flawlessly — without overheating or driving up electricity bills.
One screen is impressive; many screens are spectacular. The LED Poster supports seamless, tool-free splicing:
Retailers can start with a single unit and grow into a full video wall as their needs expand — the modular design makes it effortless.
Managing a network of displays has never been easier. The built-in Digital Management System (DMS) provides cloud-based remote control:
The LED Poster is a complete commercial solution out of the box:
The optional touch turns a digital signage screen into an interactive self-service kiosk — for wayfinding, product browsing, or customer engagement.
Riotouch operates a dedicated COB LED production facility in Dongguan, China — handling module production, cabinet assembly, system integration, and rigorous quality testing:
