Cylindrical lens-cylindrical lens technology is also called lenticular lens or micro-cylindrical lens 3D technology, and its biggest advantage is that the brightness will not be affected. The principle of cylindrical lens 3D technology is to add a layer of cylindrical 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, and the pixels of the image under each cylindrical lens are divided into several sub-pixels, so that the lens can project each sub-pixel in different directions. So when you look at the display from different angles, you will see different sub-pixels. However, the gap between pixels will also be enlarged, so sub-pixels cannot be simply superimposed. Let the cylindrical lens and pixel column not be parallel, but form a certain angle. In this way, each group of sub-pixels can repeatedly project the viewing area instead of just projecting a group of parallax images. The reason why its brightness will not be affected is that the cylindrical lens will not block the backlight, so the brightness of the picture can be well guaranteed. However, because the basic principle of 3D display is still similar to parallax barrier technology, the resolution is still a difficult problem.
Advantages: 3D technology has better display effect, and the brightness is not affected.
Disadvantages: The related manufacturing is not compatible with the existing LCD technology, and new equipment and production lines need to be put into use.
As for the commercialization of these three technologies, the technical complexity of parallax barrier is lower than that of cylindrical lens, and there are many such products on the market at present, while MLD is not competitive in technical feasibility and mass production cost; Comprehensive analysis shows that cylindrical lens technology is the trend and mainstream.
