"Naked eye 3D TV" is a combination of the current Panel we have implemented technology and engine technology. "Naked eye 3D TV" in front of the mono LCD module used in the dual-lens "panoramic image (Integral Imaging) mode" display the content of the image by image processing, can be an existing 2D images and 3D images (left and right eye two parallax) to 9 parallax images. Today, mainstream 3D stereoscopic display technology, so we still can not get rid of the shackles of special glasses, which makes its application and use of comfort are compromised.
Mainstream naked eye 3D display technology

Currently the main naked eye 3D display technology in the following two techniques are based on and improved by the. First, the parallax barrier technology, and the other for the lenticular lens technology.

A. parallax barrier technology

Show 3D movies in theaters, is widely used polarized glasses method. The parallax barrier (Parallax Barrier) technology (which is also known as parallax barrier or a parallax barrier gate technology), and polarized glasses method somewhat similar, but a need glasses, and the other do not. Parallax barrier technology was developed by Sharp Laboratories of Europe after decades of Engineers Institute. Its implementation is to use a switch to LCD screen, LCD polarizing film and polymer layer, the use of liquid crystal layer and the polarization direction of film to create a series of vertical stripes of 90 °.

These stripes tens of microns wide, through which the light on the formation of thin vertical bar gate mode, called "parallax barrier." The use of the technology is placed in between the LCD display backlight module and the parallax barrier, the three-dimensional display mode, you should see by the left eye image is displayed on the LCD screen, the opaque stripes would block the right eye; empathy , should be seen by the right eye image displayed on the LCD screen, the opaque stripes will block the left eye, left eye and right eye by a visual screen to separate the viewer to see 3D images. Defects: parallax barrier because the barrier was light, so light will come down to see the high brightness of the screen is more difficult. In addition, the resolution will be broadcast at the same time as the display image is inversely proportional to the increase in lower, resulting in lower resolution.

B. lenticular lens technology

Another called the cylindrical lens (Lenticular Lens) technology, also known as dual-lens or micro-cylindrical lens. It is compared to the parallax barrier technology, the biggest advantage is its brightness will not be affected, but the observation angle width will be smaller. It is the principle of adding a layer of liquid crystal display cylindrical lens, the LCD screen of the image plane in the lens focal plane, so that each column of pixels the image below the lens is divided into several sub-pixels, so the lens on the in a different direction each sub-pixel projection. Then his eyes watching the display from different angles, to see the different sub-pixels. However, the gap between pixels will be enlarged, it can not simply superimposed sub-pixels. Let cylindrical lens is not parallel with the pixel columns, but at an angle. This allows each group of sub-pixels, as the repeated projection area, rather than just throw a parallax image.
