Learn AV, LED, LCD, OLED and digital signage terminology — explained simply.
High-end British LED processor brand. Used for premium/TV/broadcast applications. Better HDR support.
ledThe physical frame/module that holds LED panels together. Standard size is 500×500mm or 500×1000mm.
ledDie-cast aluminum = lighter/premium. Iron = heavier/cheaper. Carbon fiber = lightest/most expensive.
ledProcess of matching brightness and color across all LED panels. Factory calibration vs on-site calibration.
ledChip-on-Board — LED chips mounted directly on PCB with protective coating. Better heat dissipation, less glare.
ledLED chips mounted directly on PCB with protective coating. Better heat dissipation, less glare than SMD.
ledMeasured in Kelvin (K). 6500K = daylight white, 3200K = warm white. Adjustable on most LED processors.
ledAn LED that does not light up. Acceptable rate: <0.01% indoor, <0.02% outdoor.

ledLED panels on flexible substrate — can be bent into curves. Used for creative shapes and columns.
ledLED panels that can be maintained from the front. Required for wall-mounted installations.
ledSMD LEDs coated with transparent glue for impact/water resistance. Good for semi-outdoor.
ledNumber of brightness levels per color channel. 14-bit=16,384 levels, 16-bit=65,536. Higher = smoother gradients.

ledDevice that sends video signal to LED panels. NovaStar is the industry standard brand.
ledIndividual LED panel unit, typically 250×250mm or 500×500mm. Multiple modules form a cabinet.
ledFreestanding LED display, typically floor-standing, used for retail/digital signage. All-in-one design.
ledFreestanding all-in-one LED display for retail/digital signage. Typically floor-standing, plug-and-play.
ledUnit of brightness. 1 nit = 1 candela/m². Indoor: 600-1500, Outdoor: 5000-10000+ nits.
ledUnit of brightness (cd/m²). Indoor LED: 600-1500, Outdoor: 5000-10000+ nits.
ledLeading Chinese brand of LED controllers and receiving cards. De facto industry standard worldwide.
ledLeading brand of LED controllers and receiving cards. Industry standard for LED displays.
ledUsing LED panels as lighting fixtures — each pixel becomes a controllable light source via DMX/ArtNet.
ledUsing LED panels as lighting fixtures — each pixel becomes a controllable light source.
ledDistance between centers of adjacent LEDs, measured in mm. Smaller = higher resolution at close distance.
ledDistance between centers of adjacent LEDs, measured in mm. P2.5 = 2.5mm. Smaller = sharper at close distance.
ledLED panels maintained from behind. Requires rear access — cheaper, used for freestanding installations.
ledCard inside each LED cabinet that receives signal from the controller. Usually NovaStar A5s or similar.
ledHow many times per second the image updates (Hz). 1920Hz standard, 3840Hz+ for video/camera work.

ledLED panels designed for frequent assembly/disassembly. Fast-lock mechanism, rugged road cases.
ledLED displays have no visible gaps between modules — unlike LCD video walls which have bezels.
ledLED panels connect without visible gaps — unlike LCD video walls which have bezels between panels.
ledCard in the controller/processor that sends signal to receiving cards. NovaStar MCTRL series.
ledSurface-Mount Device — traditional LED where each pixel has 3 separate diodes (R,G,B). Most common type.
