"Avatar", which set a record at the box office, gave viewers an unprecedented sense of realism, but to enjoy this 3D technology, you must wear special 3D glasses, which makes the audience a little uncomfortable. If you only occasionally wear 3D glasses just for watching movies, that's okay. But it would be very troublesome to wear 3D glasses for commonly used handheld devices like mobile phones. If you want to experience the fun of 3D without wearing your eyes, you need to use naked-eye 3D technology. At present, naked-eye 3D mainly includes four types: light barrier, lenticular lens technology, pointing light source and MLD technology. Light barrier These stripes are tens of microns wide, and the light passing through them forms a vertical thin stripe pattern, called a "parallax barrier." The technology uses the parallax barrier placed between the backlight module and the LCD panel. In the stereoscopic display mode, when the image that should be seen by the left eye is displayed on the LCD screen, the opaque stripes will block the right eye; for the same reason, When the image that should be seen by the right eye is displayed on the LCD screen, the opaque stripes will block the left eye. By separating the visible images of the left and right eyes, the viewer sees the 3D image. The advantage of this technology is that it has an advantage in cost. At present, 3D mobile phones like Sharp and Nintendo 3DS game consoles all use this technology. However, the screen brightness using this technology is low. Cylindrical lens technology Cylindrical lens technology is also known as lenticular lens or micro-cylindrical lens 3D technology, its biggest advantage is that its brightness will not be affected. The principle of lenticular lens 3D technology is to add a layer of lenticular lens in front of the LCD screen, so that the image plane of the LCD screen is located on the focal plane of the lens, so that the pixels of the image below each lenticular lens are divided into several sub-pixels. In this way, the lens can project each sub-pixel in a different direction. So with both eyes looking at the display from different angles, you can see different sub-pixels. The lenticular lens technology does not affect the brightness of the screen like a light barrier, so its display effect is better than the latter. Representative manufacturers using this technology include Philips in Europe, Langchen Electronics Technology in China, and Wofei 3D. Point to the light source Pointing light source 3D technology with two sets of LEDs, combined with a fast-response LCD panel and driving method, allows 3D content to enter the viewer ’s left and right eyes in a sorted manner to exchange images to generate parallax, and then make people feel the 3D 3D effect. MLD technology The MLD (mulTI-layer display) technology of PureDepth of the United States can achieve the effect of rendering 3D images of text and drawings without using special glasses through two liquid crystal panels overlapping at a certain interval. The advantage of this technology is that users will not have side effects such as dizziness and headaches, and there is not much restriction on the viewer's viewing angle. Although the current 3D technology is still immature, especially in terms of resolution, viewing angle and viewing distance, there are still many deficiencies, but with the development of technology, I believe that in the near future, we can all wear glasses without Experience realistic 3D effects on your phone. 18V Power Adapter,18V 3A Adapter,Desktop 18V Power Adapter,18V Dc Power Adapter ShenZhen Yinghuiyuan Electronics Co.,Ltd , https://www.yhypoweradapter.com
