Temasek Institute of Technology in Singapore recently announced on its official website that its nano screen technology jointly developed with A * STAR Materials Research and Engineering Company (IMRE) has made a major breakthrough. It can be realized on the 2D screen by sticking a 0.1mm thick protective film on the mobile phone Naked eye 3D Content. In addition, this 3D film can also be used for the next-generation security token function of enterprises and banks. Shenma 3D glasses are weak.
According to Dr. Jaslyn Law of Temasek Institute of Technology's Nanomaterials R&D Center, this kind of film uses IMRE's proprietary nano printing patent technology, and contains about 500000 lenses in the film less than 0.1mm. It is the refraction of these lenses that makes users have poor vision when watching the mobile phone screen through the film, thus realizing naked 3D. Since 2010, Temasek Institute of Technology's Nanomaterials R&D Center has been working hard to improve the flatness, clarity and transparency of nano films, and its technology is in a leading position in the market.
As a supplement to this film, the team has also developed corresponding iOS applications and Android applications, allowing users to convert 2D pictures on their mobile phones into 3D pictures. In addition, the team plans to develop a software development kit, which allows game developers to easily convert 2D games into 3D versions suitable for them. However, the specific time to market of the film and application has not been stated.
[About mobile phone naked eye 3D]
As we all know, one of the characteristics of human eyes is that they are large and small, and this difference in distance will further form a three-dimensional sense. One of the differences between displaying 3D graphics on the 2D display screen and the real 3D space is that it is impossible to simulate the visual differences between the far and near, so what is seen on the screen now only looks like the real world, but scientists use this principle to cause visual differences of the human eye through light refraction and other methods, so as to achieve the naked 3D display effect.
At present, there are two main open eye 3D display technologies, one is called parallax barrier technology, and the other is cylindrical lens technology.
The principle of parallax barrier technology is similar to that of polarized 3D glasses. A switch LCD screen, a polarizing film and a polymer liquid crystal layer are used to create a series of vertical stripes with a direction of 90 ° by using the liquid crystal layer and the polarizing film to form a 3D effect. Representative manufacturers and products applying such technologies include the naked eye 3D mobile phone released by Sharp and the 3DS game console of Nintendo.
Cylindrical lens technology is also called biconvex lens or micro cylindrical lens. Its principle is to add a layer of cylindrical lens in front of the LCD screen, so that the pixels of the image under each lens are divided into several sub pixels, and the eyes can see different sub pixels when looking at the display screen from different angles. This will result in visual differences and 3D effects.
According to the description of the mobile phone film, the technology adopted by the mobile phone film should be cylindrical lens technology.
