Summary:

(1) 3D viewers prefer to view 3D images without wearing glasses, without paying high price, without sacrificing resolution and with option to change from 3D to 2D mode (2) Companies promoting 3D TV with glasses need to have a re-look at the unique technique of Sumitomo 3M Ltd that satisfies most of what consumers need in 3D TV. (3) The price penalty for Sumitomo 3M technique needs to be watched. There is a clear signal here for the domination of this novel 3M film in 3D TV application

Analysis:

3D TV is a hot topic at every International Exhibit. This happened in IMID 2009, FPDI 2009, CEATEC 2009 and Display Taiwan 2009. This is going to happen in the upcoming CES show in Las vegas. Leading companies like LG Display, Samsung, Mitsubishi, Hitachi, Panasonic, Sony Corp and AUO  are vigorously pursing the introduction of 3D TV and some companies hope to achieve from the beginning of 2010. It is estimated that by 2013, shipments of 3D TV will reach 46 Million units. There are two versions of 3D display technology currently being demonstrated. One version employs lenticular sheet as a laminating film over the 2D displays. This has the disadvantage of losing resolution in addition to the limitation on viewing angular domains. The advantage is that the viewers need not have to wear special glasses and the display is not costly. The other version requires special glasses that will not sacrifice the resolution. Without glasses the display will go to the normal mode of 2D viewing. Some companies are attempting to get rid of the glasses and preserve the resolution by incorporating some changes in the structure internal to the display. But the display becomes costly. In addition the display can not be changed to 2D mode. Viewers would not like to wear glasses but would not tend to accept any compromise in performance. Viewers also would not pay high price. It is in this respect Sumitomo 3M Ltd company is unique in that they employ a film with a novel technique of driving double-edge- lit backlight which gives the advantage of viewing 3D images without glasses and at the same time preserving the resolution with option to change from 3D to 2D mode. This technique will be a 'breakthrough' in 3D TV. 3M could be dominating in this film over the next 10 years as they did with 'prism sheet' for backlight. The mode of backlight driving in combination with the unique film can be proprietary for 3M to continue their domination. The price increase as a result of this film should be something to be watched. It should not be the same story as DBEF film which used to be costly.

Some of the things we don't know about dreams

Blind People Dream

Who become blind after birth can see images in their dreams. People who are born blind do not see any images, but have dreams equally vivid involving their other senses of sound, smell, touch and emotion. It is hard for a seeing person to imagine, but the body need for sleep is so strong that it is able to handle virtually all physical situations to make it happen.

You Forget 90% of your Dreams
Within 5 minutes of waking, half of your dream if forgotten. Within 10, 90% is gone. The famous poet,Samuel Taylor Coleridge, woke one morning having had a fantastic dream (likely opium induced) - he put pen to paper and began to describe his vision in a dream in what has become one of English most famous poems: Kubla Khan. Part way through (54 lines in fact) he was interrupted by a Person from Porlock. Coleridge returned to his poem but could not remember the rest of his dream. The poem was never completed. Curiously, Robert Louis Stevenson came up with the story of Doctor Jeckyll and Mr. Hyde whilst he was dreaming.

You are paralyzed while you sleep
Believe it or not, your body is virtually paralyzed during your sleep - most likely to prevent your body from acting out aspects of your dreams. According to the Wikipedia article on dreaming, Glands begin to secrete a hormone that helps induce sleep and neurons send signals to the spinal cord which cause the body to relax and later become essentially paralyzed.

Everybody Dreams
Every human being dreams (except in cases of extreme psychological disorder) but men and women have different dreams and different physical reactions. Men tend to dream more about other men, while women tend to dream equally about men and women. In addition, both men and women experience sexually related physical reactions to their dreams regardless of whether the dream is sexual in nature; males experience erections and females experience increased vaginal blood flow.

Dreams Prevent Psychosis
In a recent sleep study, students who were awakened at the beginning of each dream, but still allowed their 8 hours of sleep, all experienced difficulty in concentration, irritability, hallucinations, and signs of psychosis after only 3 days. When finally allowed their REM sleep the student’s brains made up for lost time by greatly increasing the percentage of sleep spent in the REM stage

We Only Dream of What We Know
Our dreams are frequently full of strangers who play out certain parts - did you know that your mind is not inventing those faces - they are real faces of real people that you have seen during your life but may not know or remember? The evil killer in your latest dream may be the guy who pumped petrol in to your Dad car when you were just a little kid. We have all seen hundreds of thousands of faces through our lives, so we have an endless supply of characters for our brain to utilize during our dreams.

Not Everyone Dreams in Color
A full 12% of sighted people dream exclusively in black and white. The remaining number dream in full color. People also tend to have common themes in dreams, which are situations relating to school, being chased, running slowly/in place, sexual experiences, falling, arriving too late, a person now alive being dead, teeth falling out, flying, failing an examination, or a car accident. It is unknown whether the impact of a dream relating to violence or death is more emotionally charged for a person who dreams in color than one who dreams in black and white

Dreams are not about what they are about
If you dream about some particular subject it is not often that the dream is about that. Dreams speak in a deeply symbolic language. The unconscious mind tries to compare your dream to something else, which is similar. Its like writing a poem and saying that a group of ants were like machines that never stop. But you would never compare something to itself, for example: That beautiful sunset was like a beautiful sunset. So whatever symbol your dream picks on it is most unlikely to be a symbol for itself.

Quitters have more vivid dreams
People who have smoked cigarettes for a long time who stop, have reported much more vivid dreams than they would normally experience. Additionally, according to the Journal of Abnormal Psychology: 293 smokers abstinent for between 1 and 4 weeks, 33% reported having at least 1 dream about smoking. In most dreams, subjects caught themselves smoking and felt strong negative emotions, such as panic and guilt. Dreams about smoking were the result of tobacco withdrawal, as 97% of subjects did not have them while smoking, and their occurrence was significantly related to the duration of abstinence. They were rated as more vivid than the usual dreams and were as common as most major tobacco withdrawal symptoms.

External Stimuli Invade our Dreams
This is called Dream Incorporation and it is the experience that most of us have had where a sound from reality is heard in our dream and incorporated in some way. A similar (though less external) example would be when you are physically thirsty and your mind incorporates that feeling in to your dream. My own experience of this includes repeatedly drinking a large glass of water in the dream which satisfies me, only to find the thirst returning shortly after - this thirst drink thirst loop often recurs until I wake up and have a real drink. The famous painting above (Dream Caused by the Flight of a Bee around a Pomegranate a Second Before Awakening) by Salvador Dali, depicts this concept
