So it's not an LCD screen then?

No — an LED screen is not the same as an LCD screen, even though the names sound alike and shops often label both "LED." The difference is in how the picture is made, and it changes everything about brightness, seams and size.

The Core Difference

An LCD has a backlight behind a layer of liquid crystals; the crystals open and close to shape the image, but the light itself comes from elsewhere. An LED screen is self-emissive — every pixel is a diode cluster that produces its own light and colour. No backlight, no liquid crystal.

What That Means in Practice

Bezel between tiles?Yes, visible seamsNo — seamless surface

A Common Point of Confusion


"LED TV" is usually an LCD panel lit by an LED backlight — still an LCD at heart. A true LED screen (the kind VP LED builds) has no LCD layer at all; the diodes themselves are the pixels. So "LED" in a TV label and "LED" in a video wall mean two different things.

When to Choose Which

  • LCD — a single panel indoors, controlled light, a hard seam is fine, budget is tight.

  • LED screen — large, seamless, bright, or outdoor; anything where the wall must read as one image in any light.

Our outdoor COB series (4,500–5,000 nits, custom to 14,000) and indoor MIP P0.9 / COB P1.25 are the LED-screen answer when LCD runs out of road.

Technical Note: Grayscale and Gamma

Equation panel for the article: Grayscale and Gamma - three governing equations with numbering

Equation (1) gives the number of brightness levels from bit depth b: 16-bit processing yields 65,536 steps, which is why deep-grayscale drivers hold dark scenes smooth where 8-bit ones band. Equation (2) is the gamma response mapping digital level D to luminance; getting gamma right in the driver is what keeps shadows from crushing. Equation (3) sets the closest seamless viewing distance from pitch p.
