The development of the naked eye 3D mobile phone is a long way to go

Since the movie "Avatar" was released last year, it has set off a 3D fever at home and abroad. With the gradual maturity of technology, 3D stereoscopic display images are gradually gradually developed into naked glasses 3D with the aid of 3D glasses. Until today, naked-eye 3D has been applied to some TVs and game devices. Some Japanese and Korean manufacturers have even introduced naked-eye 3D technology into mobile phones.

The world's first naked-eye 3D mobile phone

Despite the technically significant flaws, LG Electronics took the lead in launching the world’s first naked-eye 3D mobile phone, LG Optimus 3D, at MWC2011. This phone uses Android 2.2 system, TI OMAP 4 dual-core processor platform, a 4.3-inch 3D touch display, resolution WVGA specifications (480 × 800 pixels), also supports 2D/3D image switching. In addition, LG Optimus 3D not only has 3D video playback capabilities, more amazing is that it also has two camera lenses that can support 3D image and video capture.

But from the perspective of market reactions and media voices, naked-eye 3D mobile phones do not seem to be a wise development path. Many people in the industry are deeply skeptical about the safety and health of this technology.

Some time ago the user broke the news on a portal site and he appeared dizzy and vomiting after using a naked eye 3D mobile phone. Due to the loss of confidence in continued use, the user will eventually be able to return the phone for return processing. At one point in the incident, there was a wave of confusion on the Internet. Whether naked-eyed 3D mobile phones are really safe has become the focus of the mobile phone industry.

In the end, what's the problem with naked eye 3D technology?

Dizziness stems from imaging technology

Currently, the 3D display technology adopted by many naked-eye 3D mobile phones on the market is called a "parallax barrier." The 3D imaging of the "parallax barrier" technology LCD screen is based on the poor vision of the human's two eyes. Between the two eyes of a person, there is usually a distance of about 8 cm. To make people see 3D images, the left eye and the right eye must see different images. The two images actually have a small gap, which is to simulate the actual person. When you look at the eye, this ability has a 3D stereo feeling. The screens seen by the eyes are different. This is the reason why users use the naked eye 3D mobile phone will appear dizzy phenomenon.

Dr. Ke Furen, deputy general manager of AU Optronics, which has an authoritative position in optoelectronic display, also stated that the use of naked-eye 3D technology on small screens such as mobile phone screens is problematic - mobile phones and other small screen mobile terminals are difficult to guarantee that users can always be at any time. The best visual point, so once the user's body moves, it is easy to cause dizziness.

Eye disease heart disease patients with caution

In fact, even companies that actively promote naked-eye 3D mobile phones are actually very cautious about using similar naked-eye 3D mobile phones. A company that manufactures naked-eye 3D mobile phones clearly stated in its “3D Audio-visual Relevant Precautions”: “If you have a history of photoallergies, heart disease, physical discomfort, lack of sleep, fatigue or a drink, please do not Watch 3D images, or you may get worse."

"Related Matters" also emphasized that the viewing age of 3D images is 6 years or older. When children watch 3D images, they should be accompanied by a guardian to ensure that the glasses can be properly rested. Children respond slowly to fatigue, discomfort, etc., and may experience sudden physical discomfort. Children's eyes are still in a stage of developmental growth. Please avoid children or elementary and middle school students watching long-time 3D images. Otherwise it may have an adverse effect on eyesight.

Obviously, the naked eye 3D mobile phone is indeed a very dazzling avant-garde technology, but like wine, it is not necessarily conducive to health. According to the current situation, naked eye 3D technology will mature and it is estimated that it will take 3 to 5 years.

Optical coupler is also called  optical splitter , is one of the most important passive devices in optical fiber link, is with multiple inputs and multiple output end of the optical fiber connected devices. The fiber optic splitter by the light splitting principle can be divided into the fused biconical taper (FBT type) and planar waveguide type (PLC type).
