Build a Seamless LED Video Wall · Plug & Play · No Sender Box · Direct LCD Wall Replacement
The Riotouch LED Video Wall is built from a next-generation COB LED display panel in the golden 55-inch size. Direct HDMI input with no sender box, and VESA-compatible mounting that swaps straight into an existing 55-inch LCD video wall — a seamless leap from LCD to LED.
Three things make this LED video wall the easiest LED upgrade on the market — no sender box, a standard 55-inch size, and a COB surface built to last.

Connect HDMI and the unit auto-displays up to 2K. There is no external LED sender or controller box, no rack, and no LED-controller training for the installer — it behaves like a display, not like a project.

The rear chassis carries VESA 600×400mm fixings and corner mounts, so the unit installs on the brackets already holding your 55-inch LCD video wall panels. Maintenance is front-access, and V1.1 removes the backpack for a 35mm ultra-thin mount.

COB (chip-on-board) encapsulation seals the LEDs, so the panel tolerates touch, dust and knocks far better than fragile SMD lamps. The result is 12,000:1 contrast, 170° wide viewing and a surface that keeps its looks in public spaces.
Every unit is a standard 55-inch 16:9 block with 1K native resolution, so resolution scales in clean steps and seams disappear across the COB surface.
One unit on a VESA mount — a digital sign, a meeting-room screen or a shop-front display.
Four units deliver a 4K wall with a borderless LED look, replacing four 55-inch LCD tiles.
Sixteen units form an 8K wall for control rooms, showrooms and large-format branding.
High contrast, fine detail and quick deployment — three spaces where this LED video wall replaces an LCD video wall.
➚
Eye-friendly, wide-angle viewing that stays stable through long meetings and presentations — and installs on the brackets that held the LCD wall.
➚
High contrast and fine detail so text, charts and video stay readable from the back of the room, with a flicker-free 3840Hz image on camera.
➚
Quick deployment and a borderless surface for monitoring walls, galleries and brand spaces — scale from one panel to an 8K wall later.
