OCB LCD panel for 3D glasses from Toshiba
Toshiba has developed an OCB (Optically Compensated Bend)
Liquid Crystal Display (LCD) panel for 3D glasses suitable
for watching 3D television, enjoying 3D movies, or playing
3D games.
In recent years, increasing demands for more realistic
images has been the catalyst for 3D displays in various
applications, such as movies, TV broadcasts, games, and
mobile phones.
Providing slightly different images to your left and right
eyes results in a 3D image. Two methods that are used to
separate a picture into left and right images one using
special glasses and the other is without glasses called
auto-stereoscopy. The with-glasses approach is based on
two methods, one using polarizing filters and the other
is based on time division. The with-glasses approach is
applied to movies and TV and. The new LCD panel employs
the latter time-based, with-glasses approach.
In the time-division with-glasses method, images for the
left and right eyes appear alternately, with the special
glasses working as a synchronous shutter, i.e. when the
left image appears, the left liquid crystal shutter opens
while the right shutter closes. Repeating this operation
at high speed allows the user to synthesize the left and
right images in their brain and to recognize them as a 3D
image.
If the left eye senses the right image, or if the right
eye senses the left image, double vision occurs which is
called 3D crosstalk. This phenomenon degrades the quality
of the resulting image and causes eye fatigue.
This LCD panel has used OCB technology to achieve both
high-speed response and a wide viewing angle while maintaining
high contrast. Glasses adopting these panels feature high-speed
shutter opening and closing, yielding low 3D crosstalk.
The wide viewing angle provides vivid 3D images across a
wide field of view.
