The groundbreaking technology behind HDR by Barco
We are used to thinking that more brightness always comes at a cost — brighter projectors usually mean bigger power bills. But what if there was a way to boost brightness and contrast without using more energy? With HDR by Barco, powered by Lightsteering technology, that is exactly what’s happening. Here is how it works — and why it’s changing the game for cinema projection.
What is Lightsteering?
Lightsteering is at the heart of HDR by Barco, our next-generation projection technology that brings unprecedented levels of contrast, brightness, and color to the big screen. Rather than just blasting more lumens onto the entire screen, Lightsteering takes a smarter approach: it redirects light where it’s needed most and, in the process, takes it away from areas that need to be dark. To put this in numbers, a Lightsteering projector can achieve 6 times brighter highlights and 5 times deeper blacks, resulting in a simultaneous contrast ratio of 60,000:1 which is 30 times higher than a normal cinema projector.
Think of it like a lighting designer for each individual movie frame. Instead of lighting the entire scene evenly, Lightsteering lets the projection system pinpoint bright highlights — like a spark in the dark or a glint of sunlight — while keeping deep shadows truly dark. The result? A richer, more lifelike image that feels more realistic and immersive.
More impactful images, without more energy.
In a traditional projector, brighter highlights require sending maximum light — and therefore more laser power and energy — to the entire frame, even to areas meant to stay dark. Shadows are dimmed by blocking light, but this is limited by the projector’s native contrast ratio. As peak brightness rises, black levels rise too, reducing true image depth and dynamic range.
This is where Lightsteering truly sets itself apart. Because it cleverly redistributes existing light instead of demanding more, Lightsteering can enhance contrast and brightness in specific areas of the image without drawing more power overall. You are not flooding the whole screen with light — you’re surgically directing it, frame by frame. All that stunning visual impact? It’s not coming from more energy, but from smarter energy use.
Conventional projection blocks most of the light to create differences in brightness, wasting up to 90% of light and limiting contrast. Lightsteering, instead, uses a programmable lens to direct light precisely where it’s needed, delivering brighter highlights and deeper blacks.
Why this matters for cinema?
Cinema operators today are not just looking for stunning visuals — they are also focused on operational efficiency and sustainability. HDR by Barco delivers on both fronts.
- Better image quality: Bright highlights, deep blacks, and vibrant colors like never before.
- Smarter energy use: No need to crank up the power to deliver a premium image.
- Future-ready technology: A projection system built on the trusted Series 4 platform, designed for both storytelling and sustainability.
Lightsteering turns the equation on its head: more visual impact does not mean more energy consumed. It’s a smarter, more efficient way to bring extraordinary experiences to life on the big screen.
With HDR by Barco and our patented Lightsteering technology, cinemas can now offer next-level experiences that wow audiences — without compromising on energy goals.
Because the future of cinema isn’t just brighter. It’s smarter.
