Pushing a new way of seeing
It’s no secret that much of technology is an attempt to mimic of the elegance of the human body. We are able to see the world in 3D because of how our eyes work, giving us the ability to perceive depth. The position of and how they work together as a pair makes for the most effective way for us to process information and to lock them into memory. Though a single working eye can perceive depth via certain cues, two working eyes or a stereo pair are responsible for seeing the world in 3D. In perceiving that something is 3D, the brain uses certain cues. One of most common ones is a phenomenon called stereopsis. Because of the position of our eyes in our head, an object is seen in two slightly different ways—the brain puts this information together and sees it as something with depth. This trick or cue is what makes you able to see images in the “Magic Eye” images.
The 3DVizion glasses-free Display System has got 3D imagery all tricked out.
3D isn’t necessarily new technology, the glasses with red and blue lenses are decidedly retro. But because of the high cost of technology for displays, machines to capture and create 3D images and not to mention the inconvenient glasses—it never really caught on.
Until James Cameron’s Avatar, suddenly it’s the next hottest thing! TV manufacturers have rushed to roll out 3D TVs with glasses for home use. Except the complaints have been consistent, the glasses are a hassle, the experience caused eye strain, headaches and dizziness, and the images were muddy or blurred.
3D Vizion’s glasses-free Display System has combined the advanced technology of High Def TV, the principles of 3D and computer processing to make for an effective out-of-home advertising. You catch people’s attention 58% more with 3D images that are vivid in color and crisp in detail—resulting in extreme product recall.
To make the viewing experience glasses free, the creation of 3D imagery had to be separated from its visualization. Simply put, we had to find a way to trick your eyes so that what is in reality a two-dimensional image is taken to be a 3D image. In old-school 3D, an image was projected for your left eye and a separate one for your right eye—the glasses would help your eyes perceive it in 3D. This method would also require special cameras and projectors.
With 3DVizion creative content, a 3D file format was implement that allowed the use of existing 2D creation and distribution structures—2D-plus-depth format. In other words, no need for the glasses—what the glasses were supposed to do, our screens would do it for you. Because of how the digital world works, so much more information can be put into an image additional depth information was included in every 2D image creating a 3D image.
You have 3D images that can be used with production equipment and distribution mechanisms, using similar bandwith to that of 2D. Now you can centralize content, allowing for remote controlling while applying the content on various display sizes at an optimal level.
The 3DVizion 42-inch HD display has an advanced technological design that creates distinctspots where you can see the image in rich 3D, glasses free. It allows for a multi-viewer experience without gaps , making every spot in front of it and even at a distance, a sweet spot.
To go deeper into the design, a sheet of transparent cylindrical lenses (or lenticular sheet) is fixed on a liquid crystal display (an LCD.) The LCD is chosen specifically because it is made up of pixels. But the way these lenses are attached to the LCD, the projected image of the pixels that make up the LCD is at the focus of each lens. This creates the different points of view for each eye needed to create depth perception or 3D images, glasses-free. Remember what we said earlier about stereopsis or how two slightly different views of an object makes the brain think that it sees depth or dimension. To ensure that multiple viewers can see the 3D image without blurring, the lenticular sheet is placed over the LCD so that each lens overlaps several pixels, sending the light from each pixel in a different direction. And now you have an entire view that can be enjoyed from all positions.
One more thing to ensure that resolution is not lost, another problem of regular 3D displays, slanted lenticular technology is used. Images are more lifelike and definitely clearer. You get the full picture of the 3D image glasses free and at the highest resolution possible.
Each 3DVizion Display System shows both 2D and 3D images seamlessly.The displays are able to detect the content type, a soft switch makes an imperceptible transition between the two modes. To generate a 3D image, each lens in the display bends the light in several directions. This lens effect is eliminated for 2D viewing via advanced signal processing wherein content is redistributed over sub-pixels resulting in high resolution standard viewing.
The dual mode also relies that allows for a change in the refractive capabilities of the liquid crystal used in the displays for incidental light. The lenticular layer of the display is filled with liquid crystal. Light passing from the display through the lenses is refracted or bent which creates your 3D mode. If the system recognizes a 2D format, an electrical charge runs through the liquid crystal which leaves the lenticular layer non-reflecting and light now just passes through it.
