Description
Technical field
The present invention relates to display field more particularly to field of stereoscopic display.
Background technology
" 3D " inner " D " is the initial of English word Dimension (dimension, dimension).What 3D referred to is exactly three dimensions.
Compared with common 2D pictures are shown, 3D technology can make picture become three-dimensional true to nature, and image is no longer limited to screen plane, seemingly
It can walk out outside screen, spectators is allowed to have sensation on the spot in person.
Although 3D display technique classification is various, but most basic principle is similar, is exactly to utilize human eye or so difference
Receive different pictures, then brain is lived again by being overlapped to image information, form one have before-it is rear, upper-under,
Left-right, remote-near image for waiting stereo directionals effect.
In spectacle 3D technology, we can segment out three kinds of main types again：Aberration formula, polarization type and active are fast
Gate-type.Namely usually described color point-score, light point-score and time-sharing procedure.The 3D technology of certain bore holes many now also has reality
Product, such as lens technologies, barrier technologies etc..
For traditional television set, the image that 3D TVs can show is no longer limited to plane, and picture is big
Small also no longer to be constrained by screen size, spectators can seemingly see dolphin with oneself graceful travelling, small bird from the crown gently
It skims over, these scenes that football rapidly attacks towards face door ... are all that previous planar imaging TV is beyond expression of words out.
Existing relatively traditional 3D display technology, is often required for spectators' wearing spectacles to be watched.Operation and use
It is all inconvenient.
Although having some bore hole 3D technologies now, technology is relatively immature, is not widely used.It is existing naked
Eye 3D technology is mostly to be applied to liquid crystal display.So far the bore hole 3D technology applied to the projection display is not found.
It is directed toward light source（Directional Backlight）3D technology puts into the mainly 3M companies of larger energy, is directed toward
Light source（Directional Backlight）3D technology, in mainly include being directed toward light source 3D optical facilities and arranged in pairs or groups two groups
LED, two groups of LED and the LCD panel and driving method for being directed toward light source 3D optical facilities cooperation fast reaction, allow 3D contents to sort
（sequential）The right and left eyes that mode enters beholder exchange image generation parallax, and then human eye is allowed to experience the three-dimensional effects of 3D
Fruit.But this technology is also immature, and be only only applied in liquid crystal display.It is not used widely.
