It seems that 3D will be an important technology for the display technology in 2010. 3M has recently shown an optical 3m film that allows us to watch 3D images on an LCD panel without the aid of special glasses. This has been achieved through optical dome which are on top of the film, while the rear has structures similar to the prisms 3m film. This allows the light from the LED light source to take a direction, and to project different images to each eye, giving us the illusion of 3D. It is also easy to switch between 2D and 3D. It plutùot cool, and we look forward to seeing more of 3D technology in the future 3m film. . When the sun hit the window of his room, it is possible that the heat captured by the glass can be transformed into electrical energy. This is the idea of ??3M, which is finalizing testing of the new 3m film can turn any glass surface into a solar panel 3m film. The company plans to put the news on the market later in 2012. In financial terms, the 3m film can cost 50% less than a conventional solar panel, facilitating the popularization of the energy form. However, at least for now, the 3m film is able to generate only 20% of the energy that can produce a common panel 3m film. Another plus point is its installation, because apparently the 3m film is easier to apply, does not require their own space and almost does not change the appearance of the windows of the residence. Does the proposal from 3M will be a success with the public '. 3m film.
