High brightness is a specification, not an adjective

Every supplier calls their panel bright. The number that matters is measured in nits, and the number you need is decided by the light behind the viewer, not by the size of the screen.

A display fails in daylight for one reason: the light falling on the glass is stronger than the light coming out of it. A television in a living room puts out 300 to 500 nit and looks perfect, because the room is dim. Put that same panel behind a shop window at noon and it turns into a mirror.

High-brightness LCD solves this by pushing far more light through the panel — up to 5000 nit in our line — and by changing the panel structure so that the extra light survives the trip. Brightness alone is not enough, which is the part most specifications leave out.

Rule of thumb

How much brightness each environment needs

Indoor, away from windows	700 – 1000 nitA normal commercial panel is adequate here.
Indoor, bright lobby or atrium	1500 – 2500 nitReflected daylight is the problem, not direct sun.
Behind glass, street-facing	2500 – 4000 nitOur Window Display line starts here.
Behind glass, direct sun	4000 – 5000 nit55 ″ FHD reaches 5000 nit.
Fully outdoors	4000 cd/m² + IP65Sealing and climate control matter as much as the nits.

Guidance, not a guarantee — reflectivity, mounting angle and glass coating all move the number.

What high brightness costs you if you get it wrong

Too little brightness

The display is unreadable for the hours that matter most — the hours the street is busy.

Too much brightness indoors

You pay for power and cooling you do not need, and the panel ages faster than the installation.

Brightness without the right polarizer

The picture is bright and invisible to anyone wearing polarized sunglasses.

Brightness without heat management

A bright panel behind glass runs hot. Without a temperature sensor and a fan, it throttles or it darkens.

High brightness, answered

What is a nit?

One nit is one candela per square metre — the light a display emits per unit of area. A phone in sunlight mode is about 1000 nit; our brightest panel is five times that.

Is cd/m² the same as a nit?

Yes, exactly the same unit. Outdoor specifications tend to use cd/m², panel specifications tend to use nit.

Does higher brightness shorten panel life?

Running any panel at its ceiling all day shortens it. That is why our window displays carry a light sensor: brightness follows the ambient level instead of sitting at maximum.

Why do you use Direct BLU above 2500 nit?

Edge-lit backlights run out of headroom and uniformity at high output. Direct backlights sit behind the panel and can push more light more evenly.

Not sure which number applies to your site?

Send us the location and the mounting direction. We have specified panels for shop windows, bus shelters and stadium concourses and the answer is rarely the obvious one.
