Description
The Sharp LM551 is a 55" interactive display from Sharp's LM Series, aimed at small meeting spaces and interactive signage where responsive, professional-grade touch collaboration is needed. Its VA panel with Direct LED backlighting produces native 3840 x 2160 4K UHD resolution at 500 cd/m2 brightness and a 5000:1 contrast ratio. Infrared touch technology supports real 20-point multi-touch with +/-1mm accuracy and recognises finger, gloved and dual-tip stylus input, giving a natural pen-on-paper writing feel. An integrated Android 14 CTS-compliant SoC (quad Cortex-A53 plus quad Cortex-A73, 4GB RAM, 32GB storage) runs a built-in whiteboard, annotation overlay and wireless screen sharing directly from the display. The LM551 connects via three HDMI inputs (ARC on HDMI 3), an HDMI output, two USB-C ports (one with 65W power delivery and DisplayPort Alt Mode 1.4), three USB-A 3.0 ports, USB-B, LAN and RS-232C, and is rated for 18/7 operation.
Key features
Real multi-touch with up to 20 simultaneous touch points and +/-1mm accuracy for finger, glove and stylus input.
Octo-core SoC with 4GB RAM and 32GB storage drives whiteboard, annotation and wireless sharing apps without an external computer.
3840 x 2160 resolution with 5000:1 contrast ratio keeps content sharp and legible in typical office lighting.
One USB-C cable carries video, data and 65W laptop charging for a fast, tidy room setup.
Rated for extended daily use and covered by Sharp's 3-year warranty including the backlight.
