Fast refresh rate (typically to reach 120Hz) left eye and each 60Hz of right eye fast refresh can just allow people not produced to image and tremble
Innervation, and keep and 2D video identical frame numbers.
It is mainly by liquid crystal glasses come what is realized, and its ophthalmic len is substantially that can control the two panels of ON/OFF respectively
Liquid crystal layer in liquid crystal display, glasses has black and white two states, and white i.e. pellucidity is shown as usually, will be become after energization
Black.By IR transmitters, allow between 3D glasses and screen and realize precise synchronization.Alternately it can be drawn right and left eyes on display screen
The broadcasting in face, when playing left picture, left eyeglass is opened, and right eye mirror is closed, and spectators' left eye sees the picture for needing to allow left eye to see
Face, what all can't see right eye.It is that right eye sees right picture playing right eye picture, left eye can't see picture, allow like this or so
The respective picture in left and right is respectively seen in eye, so as to realize 3D stereoeffects.This process is alternately at least up to 120 times/per second, people
Eye can just enjoy the coherent 3D pictures without flicker, so active 3D Display Techniques require that the refresh rate of screen is at least up to
120Hz。
