Abstract
The embodiments of the present disclosure disclose a display apparatus. The display apparatus includes: a display unit having a plurality of pixel units; a lens unit; and a light path adjustment unit disposed between the display unit and the lens unit and configured to adjust a light path of light emitted from at least one of the plurality of pixel units, such that the adjusted light path has a predetermined range of incident angles with respect to the lens unit.

A display apparatus, comprising:
- a display unit having a plurality of pixel units;
- a lens unit;
- and
- a light path adjustment unit disposed between the display unit and the lens unit and configured to adjust a light path of light emitted from at least one of the plurality of pixel units, such that the adjusted light path has a predetermined range of incident angles with respect to the lens unit,
- wherein each of the pixel units corresponds to one virtual object pixel and one virtual image pixel,
- wherein a first micro-lens corresponding to a first pixel unit is configured such that:
- tan
-
-
- α
- =
- h
- d
-
-
- and
-
-
- tan
-
-
- β
- =
- H
- d
- ,
- where α is an angle between a line connecting a first vertex of a first virtual object pixel corresponding to the first pixel unit to the first pixel unit and a normal of the display unit, β is an angle between a line connecting a second vertex of the first virtual object pixel to the first pixel unit and the normal:
- h is a distance from the first vertex to the normal, H is a distance from the second vertex to the normal, and d is a distance from the first pixel unit to the first, virtual object pixel along a direction of the normal.
