Xiaomi debuts world’s first mass-produced transparent OLED TV

Xiaomi has unveiled what it claims is the world’s first mass-produced transparent TV, the 55-inch Mi TV LUX Transparent Edition. The screen itself is only 5.7mm thick, will cost 49,999 Yuan (approximately $7,200 in the United States), and goes on sale in China on August 16.

The idea of transparent TV might seem like it’s straight out of a sci-fi movie, but we’ve seen examples of transparent displays going back several years. What’s different this time is that Xiaomi’s Mi TV LUX Transparent Edition is the first transparent display to be sold as a generally available TV for the home.

To achieve transparency, the Mi TV LUX uses OLED technology. OLED TVs possess a number of advantages over their LED TV cousins, like astonishing thinness, deep black levels, and the ability to take on non-flat shapes for curved screens. But it is OLED’s ability to allow light to pass through it both directions that Xiaomi has taken advantage of to create the Mi TV LUX Transparent Edition.

Normally, OLED TVs aren’t transparent because they possess a rear reflective layer that is opaque, but the Mi TV LUX Transparent Edition uses a variation of OLED called Transparent OLED (TOLED), in which that rear layer is made from a transparent material.

Additionally, Xiaomi has taken all of the electronics and audio/video connections like speakers, HDMI ports, and antenna inputs — which normally sit in a thin cabinet behind the screen — and stowed them beneath the OLED panel in an integrated round stand.

The question we have is what sacrifices may have been made to picture quality in order to create the TV’s transparent look? Not to knock Xiaomi’s technical prowess, but LG has been the world leader in OLED technology for years and it has yet to offer a transparent display for home use.

Also, as other publications have pointed out, Xiaomi’s press pictures appear to show examples of blended images, where a part of the TV’s screen displays content (like the butterfly in the example above) while the rest of the screen remains transparent. Presumably content will need to created specifically to achieve this effect, but how do you go about creating the deep, inky black levels that have always been a hallmark of OLED TVs if light can pass through the screen from behind?

There’s no word yet on when or if the Mi TV LUX Transparent Edition will go on sale in the U.S., but hopefully, we’ll find out just how good of a TV it is before that happens.

Panasonic’s latest OLED TVs are the first with Amazon Fire TV built-in

Fans of Amazon's Fire TV experience haven't had a lot of options when it comes to buying TVs that don't require an external streaming device in order to access Amazon's streaming interface. But today, that changes in a big way with an announcement from Panasonic that its newest OLED TVs will have Fire TV built-in, making them the first OLED TVs to do so.

Initially, the global partnership between Panasonic and Amazon will focus on two OLED TV models, the Panasonic Z95A, which will be available in 55- and 65-inch screen sizes, and the Panasonic Z93A, which will come in a 77-inch size. However, it's expected that Panasonic will roll out additional Fire TV-based models in the future.

What is QD-OLED? The hybrid TV tech fully explained

It’s hard to beat the vibrant colors and leap-off-the-screen brightness that the best QLED TVs deliver. Then again, it’s equally difficult to replicate the insane black levels, ultra-rich colors, and incredible contrast of an OLED set. But what would happen if TV manufacturers decided to combine both of these amazing picture technologies? Such a leap of faith has already been taken, friends, and the result is the QD-OLED.

Introduced a couple of years back, QD-OLEDs are available from brands like Samsung and Sony, as well as Alienware (if you’re shopping for a QLED computer monitor). On paper, this display tech combines the best parts of both QLED and OLED models, which means these sets should be capable of getting nice and bright, while still delivering unbelievable contrast levels and a wide color gamut. But does this brilliant amalgamation actually deliver? Let’s take a closer look at the world of QD-OLEDs to find out.
