LCD (Liquid Crystal Display) is the dominant display technology in indoor digital signage. LCD panels modulate light from a backlight (typically LED-based) through layers of liquid crystals and color filters to produce the visible image. Modern professional LCD displays are available in sizes from small countertop screens (7"–24") to large-format displays (98"+), with 4K and 8K resolutions and brightness from 300 to 5,000+ nits.

LCD remains the default for most signage scenarios because of its balanced cost-quality profile, broad vendor ecosystem (Samsung, LG, Philips, NEC, Sharp, BenQ and many others), and mature thermal and reliability engineering. Livesignage is certified across all major LCD signage display lines and runs natively on their integrated SoC players.
