It may be a sci-fi staple \u2013 people working advanced computers with transparent screens \u2013 but such computers really do exist. We saw one at the MWC last week, the Lenovo concept laptop<\/a>. This was never the most practical design, but it sure looks cool. And phone makers thought so too.<\/p>\n

A long time ago (it has been 15 years!) the LG GD900 Crystal<\/a> was announced. It was a slider phone with a 3.0\u201d touchscreen and, more importantly, a transparent keypad. This didn\u2019t have keys as such, it was more of a touchscreen without the screen \u2013 just a transparent glass with cool white illumination and a capacitive touch layer.<\/p>\n

The LG GD900 Crystal had a transparent slide-out keypad<\/strong><\/span><\/p>\n

The effect worked best in the dark when the hazy glow of the keypad really made it look like a crystal. It\u2019s also a bit of a missed opportunity as, looks aside, this was just a keypad \u2013 LG could have enabled some navigation gestures.<\/p>\n

With just a 3\u201d display, your thumb covered up most of the content while scrolling. The touchscreen did support multi-touch with pinch zoom, so some gestures on the touchpad\/keypad would have been cool.<\/p>\n

A few months after the Crystal came the Sony Ericsson Xperia Pureness. Despite the name, this was not a smartphone, but it did have a unique trick \u2013 a transparent display. It sounds more impressive on paper than it was in reality.<\/p>\n

The display was indeed transparent, but it was a tiny 1.8\u201d monochrome display panel and it was very difficult to use. As you can see, we mostly photographed it on a background as otherwise ambient light made it quite illegible. And this tiny monochrome display made any smart functionality a non-starter. Functionality was so limited that the Pureness didn\u2019t even have a camera.<\/p>\n

Keep in mind that this was a premium \u20ac600 phone! What it did have was a subscription to a concierge service, similar to Vertu phones (though the Xperia\u2019s plasticy build wasn\u2019t as appealing to rich folk as the precious materials of the Vertus). And while it looked unique and was certainly a conversation starter, the Pureness was quite underwhelming.<\/p>\n

Around a year later<\/a> a rival arrived \u2013 the Lenovo S800<\/a>. This was similar to the Xperia with a transparent display over a traditional keypad, though this one was larger at 2.4\u201d. It was still monochrome, though.<\/p>\n

There have been some concept devices too. For example, Iron Man 2<\/i> featured a fictional LG phone that was all transparent touchscreen, save for a thin frame around the glass. This was just a practical prop with CGI graphics, of course.<\/p>\n

Here\u2019s another odd one \u2013 the Mobiado and Aston Martin CTP002 concept device<\/a>. This was a transparent Android phone with all the electronics stuffed in the side edges of the device.<\/p>\n

Making a transparent display is not that difficult \u2013 in fact, LCDs are naturally transparent, just remove the backlight and you can see right through it. OLED is transparent too, that is how under display fingerprint readers and cameras work. The capacitive touch layer is transparent as well.<\/p>\n

That doesn\u2019t mean that there are no challenges \u2013 the motherboard and battery certainly aren\u2019t transparent. That is why LG and Sony Ericsson limited the transparent window to a section of the phone, moving the opaque components out of the way. And despite a few claims to the contrary, no one actually managed to build a transparent all-touch smartphone.<\/p>\n

There\u2019s also the other issue \u2013 a transparent display is hard to read, unless you put a plain background behind it, but that defeats the purpose. Maybe dimmable glass like we saw on the OnePlus Concept One could provide an opaque background when needed and then go transparent to look cool.<\/p>\n
