Latest Display Technologies in India – Explained – There has been an incredible innovation spree in the television market in the last decade coupled with what seems a budget smart TV revolution which has made high-quality smart TVs available to the general public at prices lower than that of nowadays’ smartphones [even the cheap ones]. Manufacturers have made huge strides in making display panels as cost-effective as possible. Not to mention the different latest picture-optimization techniques or display technologies that have helped on the software side of things. In this post, we will take a look at the latest display technologies or picture optimization techniques that you should look for when buying a TV in India.
Display Resolution in TVs – Explained
4K & 8K Display Resolution in Televisions
For the longest time, Full HD [1920 x 1080 pixels] resolution has been the upper cap that limited further clarity in our TVs in terms of the number of pixels. But in the last few years, the new standard has increased to 4K Ultra HD i.e. 3840 x 2160 pixels of resolution which is a significant improvement over Full HD [well, twice as much in terms of the number of pixels and three times that of regular HD resolution]. But we are in 2020 now, and the latest technologies are even better than 4K – it’s 8K Ultra HD or 7680 x 4320 pixels of resolution. Although most people would be just fine with 4K resolution on their TVs as the prices increase exponentially for anything above 4K TVs. And to be honest a display with 8K resolution is a bit of an overkill. Not to mention that 8K content is really hard to find currently and that’s not going to change anytime soon.
Back in 2016, when asked about the future of TVs, Netflix’s Chief Product Officer said – The future of TVs is in better pixels, not just more of them. 8K Resolution only makes sense if you are going to sit really close to your TV which you shouldn’t be doing anyway if you care about your eyes at all. And with that statement from Netflix’s Chief Product Officer, it is safe to say that 8K content is not going to be here anytime soon. So for the time being, 4K Ultra HD is the best resolution you can and should get. But as Netflix’s Chief Product Officer said having more pixels isn’t enough, their quality needs to be good as well. That’s where HDR and other picture optimization techniques like Dynamic Crystal Colour and Micro Dimming come in.
Types of Display Panels – LED, OLED & QLED
LED (Light Emitting Diode) Display Panels
LED [Light Emitting Diode] display panels are currently the most popular type of display panels used in commercially available TVs. These panels consist of thousands of diodes which emit specific coloured light when an electric signal is passed through them. LEDs are the most power-efficient sources of light which makes them perfect to be used in display panels. Aside from being energy-efficient, LEDs produce the brightest light with the highest intensity. Recent advancements in the manufacturing of LED panels has enabled TV brands to sell LED TVs at really cheap prices [even less than 10000₹] and still earn a profit.
OLED (Organic Light Emitting Diode) Display Panels
OLED [Organic Light Emitting Diode] display panels are different from standard LED panels in the sense that they don’t need a backlight i.e. they are emissive display panels. As a result, these OLED panels are way thinner and more efficient than LED panels which do require a white backlight. Not only these panels are thinner and more efficient, but they also provide improved image quality with better contrast, much higher brightness, wider viewing angles, a wider colour range and much faster refresh rates. Aside from all these advantages OLED technology shows further potential in foldable, flexible and even transparent display technologies. So yeah, OLED technology in televisions does have a bright future (pun intended).
QLED (Quantum Light Emitting Diode) Display Panels
QLED [Quantum Light Emitting Diode] display panels use the QLED technology developed by Samsung which is a direct competitor to LG’s OLED technology. Instead of light-emitting diodes, QLED displays use tiny nanoparticles called quantum dots to display bright and beautiful colours. Like OLED displays, QLED displays do not require any white backlight. Quantum Dots (ranging from 2-10 nanometers in diameter) are capable of producing highly saturated colours and higher brightness without sacrificing any contrast. The brightness of these displays [which ranges from 1500 to 2000 nits] makes regular displays look like tiny bulbs in comparison. Considering all these factors, QLED displays are arguably better than OLEDs.
HDR [High Dynamic Range]
What is HDR (High Dynamic Range)?
Another major technology influencing picture quality in TVs is HDR [High Dynamic Range] technology. Dynamic Range is a photography term which has now become relevant in display technology. It basically means the contrastive difference between the picture’s brightest whites and the darkest blacks. So basically a higher dynamic range makes the picture more life-like by displaying more shades and depth of colour. You may have noticed that when you increase the brightness of a non-HDR display, it becomes whiter. This is not the case with HDR displays as they can theoretically deliver around 5000 nits of brightness with the same amount of contrast. Any increase in the number of pixels on a display cannot recreate this effect.
Different HDR (High Dynamic Range) Formats
HDR10 & HDR10+ – HDR10 is a format that is more generic as its parameters (like brightness and contrast for example) are applied equally throughout a specific piece of content. The HDR10+ format developed by Samsung, on the other hand, takes a frame-by-frame approach in the mastering process. But Samsung’s HDR10+ accomplishes this feat by using the picture’s dynamic metadata. Both formats are royalty-free.
HLG (Hybrid Log Gamma) – HLG is an HDR format that is used in TV broadcasts. It was developed by a joint endeavour between BBC and Japanese broadcaster NHK. It takes standard dynamic range and high dynamic range images and combines them into one feed and shows the HDR picture in its full glory.
Dolby Vision – Dolby Vision is an HDR format developed by Dolby Cinemas which is similar to HDR10+. It uses the picture’s dynamic metadata to boost its HDR frame-by-frame.
HDR by Technicolor – This one is the least known of the main four HDR formats. It’s the consequence of a collaboration between LG and Technicolor. But LG is the only manufacturer to support the format so far.
Other Picture-Optimization Techniques
Wide Colour Gamut – Wide Colour Gamut or WCG is a technology that often comes together with HDR to produce better colour reproduction. It’s like HDR but for colour saturation and not for contrast. In simpler terms, WCG produces redder reds, greener greens and bluer blues, etc. If your TV has HDR, chances are it already has Wide Colour Gamut as well.
Dynamic Crystal Colour – Dynamic Crystal Colour was developed by Samsung not so long ago. What this technology mainly does is distinguish between over a billion hues and display them separately with mixing them. That’s 64 times more hues than a normal 4K TV.
4K Upscaling – 4K Upscaling as the name suggests is an upscaling technology that upscales existing lower resolution content to 4K by detecting colours on the surrounding pixels and filling the blank pixels up using that as a reference. It won’t be as clear as true 4K but it’ll be much better in term of resolution. This is one of the latest display technologies that is especially useful in India.
