Display Device and Wearable Glasses

A wearable glasses apparatus comprising:

• a holding unit for holding a relative position relationship between wearable glasses apparatus and a user when the user wears the wearable glasses apparatus;
• a left display unit;
• and
• a right display unit,
• wherein, the left display unit comprising:
• a left image source for generating left image light which is corresponding to left image data and being watched by a left eye of the user according to the left image data;
• a first left optical component for receiving the left image light and making polarized light having a first polarization direction in the left image light to pass through;
• and
• a second left optical component for receiving the polarized light having the first polarization direction and converting it to a polarized light having a second polarization direction which is perpendicular to the first polarization direction, and propagating the polarized light having the second polarization direction to the first left optical component, to make the polarized light having the second polarization direction to be reflected to the left eye of the user by the first left optical component;
• and, the right display unit comprising:
• a right image source for generating right image light which is corresponding to right image data and being watched by the right eye of the user according to the right image data;
• the first right optical component for receiving the right image light and making polarized light having a third polarization direction in the right image light to pass through;
• and
• a second right optical component for receiving the polarized light having the third polarization direction and converting it to a polarized light having a fourth polarization direction which is perpendicular to the third polarization direction, and propagating the polarized light having the fourth polarization direction to the first right optical component, to make the polarized light having the fourth polarization direction to be reflected to the right eye of the user by the first right optical component,
• the left image data is same as or different from the right image data, and the first polarization direction is same as or different from the third polarization direction, and the second polarization direction is same as or different from the fourth polarization direction.
