True 4K UHD COB LED Screen with 20-Point Touch Interactive and Wireless Projection COB LED Display for Conference

A 6000×3375mm COB LED wall that natively resolves 3900×2194 pixels, so real 4K UHD content is displayed without scaling. Touch film, wireless casting and built-in Android control turn it into a working surface rather than a passive screen: presenters walk up, cast from a laptop or phone, annotate on the wall and switch sources in seconds.

• True 4K UHD canvas: 3900×2194 native pixels exceed 3840×2160, so CAD drawings, 4K video and dashboards show 1:1 without downscaling blur.
• 20-point touch interaction: walk up, write, drag and annotate directly on the COB surface; the matte flip-chip face is finger-print resistant and safe for daily touching.
• Four-way wireless projection: AirPlay, Miracast and DLNA built in, no dongle, no driver install, four participants on screen at once for comparison reviews.
• No visible seams across 100 cabinets: die-cast cabinets hold 0.1mm tolerance so a 6-meter wall reads as one continuous panel, which matters for a touch surface.
• Flicker-free on camera: 3840Hz refresh and 16-bit grayscale keep broadcast, hybrid meeting and studio recording clean.
• Full front service: modules, receiving cards and power supplies are all replaced from the front, so a wall-mounted install on a finished conference wall stays serviceable.

Executive boardrooms, design review and command centres, university lecture halls, training rooms, showroom interactive walls, hotel conference floors, government briefing rooms and experience centres where 4K detail plus touch collaboration is specified.

Supplied as a complete interactive system: LED wall, touch film, Android controller, sending card, wireless casting module, wall bracket and cabling. We provide layout drawings, a signal topology diagram, and remote commissioning. Optional: mobile stand, OPS PC module, video conferencing camera bracket.
