HTC and LG have set the tone, being the first to launch the smartphone models with 3D screen, and now Nokia and Samsung are preparing to join the new trend, patenting the technologies ready for the next generation of 3D smartphones.
Even though until now, auto-stereoscopic 3D screens installed on phones like LG Optimus 3D and HTC Evo 3D were viewed more as marketing tricks designed to boost sales by taking advantage of users’ willingness to try something new, the lack of credibility affecting currently the niche of 3D gadgets does not seem to discourage other producers to join with their own 3D smartphone models.
For the patent application made by Nokia, the company describes a display of “Dual-mode two-dimensional / three-dimensional display” type. The screen capable of operating in 2D mode can be switched to 3D mode to display two different images simultaneously, each for only one eye. Samsung’s patent describes a 3D display with similar properties.
From the descriptions provided by the companies, we deduce that the new 3D screens have the same operating principle as those used by HTC and LG, using alternating rows of pixels to compose the two constituent images, then separated using a polarizing filter, provided to enable the observation of only those rows of pixels that make up the image for an eye or another.
Even if we cannot say with certainty exactly when we can admire the new products from Samsung and Nokia, we can expect the 3D screens contained by them, though based on technologies more finished, not to revolutionize the market of 3D phones and tablets. Among the few things that can be said with sufficient certainty at this point is that Nokia will be based on Windows Phone operating system, while Samsung will not depart from the Andoid platform.
