You might not have realised it, but Light Emitting Diodes (LEDs) have taken over our world. And for good reason.
LEDs are energy efficient, long lasting, and vibrant which is why you can now find them in your ceilings, in your phones, those annoying squeaking-flashing shoes worn by your nephew and, since the mid-2000s, in our TV screens.
In fact, LEDs are one of the main reasons that our TVs have gotten bigger, brighter and slimmer in recent years. But now that the LED revolution has peaked, what could possibly make Luke Cage look better on your TV screen?
Sony has the answer - Backlight Master Drive™ Technology, which can now be found in its latest BRAVIA™ Z9D 4K HDR with Android TV™ that’s now available in Singapore. But what does this new technology mean for your viewing experience? Let us break it down for you:
1. Its brilliance is undeniable
You know what’s better than lots of LEDs in your television screen? Even more LEDs.
The simple reason being the more individual diodes (think of them like pixels), the greater the potential for a brighter and more accurate picture. That’s why the starting point for Sony’s Backlight Master Drive™ is an ultra-dense bed of LEDs, cramming more diodes onto a single panel than they have ever managed before.
But quantity doesn’t always mean quality unless you have them under total control. In the case of Sony’s new technology, the mass of LEDs are individually and discretely managed by an innovative new algorithm that keeps them all focused on the task in hand (see more below). That means instead of blotchy undefined images and blurry edged pictures, you’ll get incredible clarity and amazingly detailed colour segregation, which truly puts the ultra in ultra-HD.
2. Its laser sharp focus means incredible detail
One problem that has plagued LED televisions since their inception is light diffusion. For once too much of a good thing, the brightness of the diodes themselves would often cause a flare effect when the screens were called to reproduce highlights – an issue that was especially noticeable when light-filled images such as stars, the moon or a glittering skyscraper were set against dark backgrounds. In the worst case, the television would attain the smudgy, overexposed effect of a badly post-processed Instagram selfie.
The Backlight Master Drive™ directly tackles this by featuring a calibrated beam LED design, which focuses the emitted light from each individual diode into a clear straight beam. This reduction in light diffusion allows Sony’s latest BRAVIA™ Z9D series to produce images with incredible contrast and pin sharp accuracy minus any blurry afterglow.
3. Step into an all new visual reality
We’ve already explained how Sony’s BRAVIA™ Z9D TVs offer more brightness through more LEDs but that can only truly enhance the picture quality if it’s fully controllable. That’s what Sony’s Improved X-tended Dynamic Range Pro™ brings to the table.
By accurately managing the light output of the screen, it can make specific areas darker or brighter to truly reflect the image being displayed. It works so well that Sony reckons it increases the dynamic range to three times that of a conventional LED-backlit TV and enhances any video to near HDR quality.
This means contrast, contrast and more contrast - without losing any of the details or the gradients in between the darkest and the lightest part of the image. That increased level of contrast ensures that colours look brighter and more natural.
4. It does all the brainwork for your viewing pleasure
The 4K HDR Processor X1™ Extreme found in the new Sony BRAVIA™ Z9D TVs has as much as 40% more real-time image processing, which means it’s working even harder to upscale the quality of everything you watch.
That all sounds fine and dandy but what does it really mean? Well these new processors can be said to offer improved picture quality in three key areas. The first comes courtesy of the inbuilt Object-based HDR remaster technology, which actually analyses the colours of individual objects as they appear on screen and then adjusts the contrast accordingly. By specifically enhancing the individual objects it reproduce greater depth, more detailed textures and ultimately more realistic looking pictures. Count the individual petals on that flower, see the true blues of that mountain lake or watch that wind ruffling the mane of that regal lion – it brings nature into your front room.
But that’s not all this humble chip can do, it’s working equally hard to bring you ultra-realistic images through powerful image improvement dual database processing. One database reduces image noise while the second works to upscale the image clarity and resolution. Both databases reference tens of thousands of pieces of before and after data to bring you a more accurate image.
And the 4K HDR Processor X1™ Extreme has one more trick to play in the area of Super Bit Mapping 4K HDR. In layman’s terms this simply means you get to experience much smoother colour gradations, compared to the typical blocky colour splits you get on more traditional TVs. In fact, Sony reckon it delivers up to 64 times the colour levels of a conventional display.
A 4k Symphony
What Sony’s Backlight Master Drive™ Technology means for the viewer is this: a symphony for your eyes. Except that each instrument of this optical orchestra is perfectly clear and defined, yet somehow working in exquisitely synchronised tandem to create a vision greater than the sum of its parts.
With the detailed images bearing noise-free contrast it’s capable of, it’s the best tech you can possibly use for watching shows that have embraced the drama of high contrast imagery and 4K quality, think Game of Thrones, Luke Cage, or Daredevil.
