Toshiba hasn’t abandoned 3D display with a new type of 4K screen that’s “glasses free”
Stephan Jukic – December 26, 2014
3D display has spent some time now seeming to be a nearly dead technology as far as consumer developments are concerned. This is partly because most industry players are now heavily distracted by 4K ultra HD display technology and partly because, quite frankly, 3D display technology never really took off, even when it was getting attention.
However, as far as the developers at Toshiba Electronics corporation are concerned, that’s no excuse for failing to experiment.
The company that has brought us a number of 4K laptops and a few ultra HD 4K TVs is now also working on building a new kind of LCD display screen for laptops which incorporates 3D viewing into a 4K display in a way that creates the three-dimensional effect without the need for those silly looking glasses.
The company is planning on incorporating this development into a new 15 inch 4K LCD PC panel in the near future.
According to Toshiba, the technology in question is something completely new, developed by their engineers, which uses an ultra-high definition LCD “gradient-index lens” with voltage applied to its liquid-crystal cells in a way that allows the screen it’s used in to be switched between 2D and 3D display modes.
Furthermore, in contrast to almost any electronic 3D display technology yet developed, the new type of 3D screen won’t require users to put on the special glasses common to 3D technology. In addition to this remarkable development, the screen doesn’t suffer any degradation in brightness when switched to 3D mode or deterioration in image clarity when taken back to 2D mode.
According to Toshiba’s engineers, “The lens system reduces the abnormal alignment of liquid crystal molecules near the boundaries of liquid crystal a liquid crystal lens, reducing crosstalk to 2 %, against 5% in conventional 3D displays”. This feat is achieved by more precisely optimizing the orientation of liquid crystal molecules as well as the angle of the liquid crystal gradient-index lens relative to the polarization of the LCD panel itself.
In other words, the much more precise alignment of liquid crystals inside the new 4K screen creates an image that enjoys five times the resolution of normal 3D and that can thus be viewed clearly even on what would normally be a strictly 2-dimensional screen.
Toshiba is planning on unveiling this new 3D/2D/4K display screen at the upcoming CES 2015 show in Las Vegas, Nevada in January and eventually hopes to apply the technology to TV and PC screens of various sizes, allowing users to experience 3D on their ultra HD 4K screens without the inconvenience of glasses.
