Left-eye image is can receive, at the T2 moment, the second polarised light is incident to the left eyeglass lens and right eye eyeglass of polarization type 3D glasses, uses
The right eye at family can receive eye image, after left-eye image and eye image have respectively entered the left eye and right eye of user, pass through
The synthesis of brain, to form 3D stereoscopic effects.
In embodiments of the present invention, the viewing number that display device is watched by detection generates control according to viewing number
Signal controls the deflection direction of multiple mirror units according to control signal, will pass through the first of phase delay structure formation
Polarised light and the second polarised light carry out the adjusting of exit direction.By multiple mirror units, phase delay structure shape will be passed through
At the first polarised light and the second polarised light carry out exit direction adjusting, ensure be not lost the first polarised light and second polarization
In the case of the transmitance and product yield of light, realize that the vertical angle of view of display device is adjustable；Meanwhile different sights can be met
It sees the viewing demand under number, in the case where ensureing visual range and 3D display effect, is suitable for certain height personnel and watches
Privacy requirements.
