Since the advent of 3D TV, many manufacturers have begun to call out the slogan of naked-eye 3D. However, today, naked-eye 3D technology still remains a mystery. It has been seen and nobody has bought it because you cannot buy it at all. . However, there are a lot of consumers who want to buy it. So what is blocking the development of naked eye 3D? Will naked-eye 3D technology be seen in next-generation smart TV products? Look down together.

The advantage of naked-eye 3D is self-evident, you can watch 3D movies or pictures without 3D glasses. No need to bring 3D glasses is really cool. Not to mention that it is miserable to wear glasses with children's shoes. At present, both domestic and foreign brands are trying to develop, and achieved phased results.

At the 2014 CES show, a company launched a naked-eye 3D solution called StreamTV Networks. They use the cylindrical lens naked eye 3D principle, there are several points of more characteristic features: First, we can freely adjust the depth of the 3D, this Mainly used to prevent dizziness caused by long-term viewing of 3D video, we can adjust to the most comfortable position according to the location of home TV and the different feelings of each person on the depth of field.


Second, they can achieve real-time conversion of ordinary 2D TV program signals into 3D output. The effect is still quite obvious. Especially for sports programs, the three-dimensional sense is extremely strong. Of course, the effect is still inferior to the output effect of 3D film sources. The picture is that we turn the news simulcast into 3D signals in real-time on the scene. Of course, the camera can't shoot 3D effects, and it is still very good from the human point of view.

The third is the lower cost. We understand that StreamTV Networks technology will not bring excessive cost pressure to TV manufacturers. They can sell naked-eye 3D TV terminals to the market at a lower cost.


In addition, naked eye 3D technology also has some bottlenecks.

First of all, the definition has not been high enough; secondly, the perspective has always been limited. The maximum viewing angle of these naked-eye 3D TVs that Toshiba had exhibited is still only about 40°. Once viewers’ eyes are out of this narrow area, they will still see double images on the screen. So far, naked-eye 3D TVs have only been used for commercial purposes due to factors such as price, source, etc. For home naked-eye 3D TVs, it is likely to require a relatively long period of technical completion and market planning, but it should be noted that naked-eye 3D The emergence of this will surely become the most mature form of 3D TV.
