Abstract
A see-through type display apparatus includes an image projector configured to output image light, a waveguide configured to receive the image light output from the image projector and transmit the image light to a user's view, and a first lens having a negative refractive power and a second lens having a positive refractive power, which are arranged on both surfaces of the waveguide. Each of the first lens and the second lens includes one or more meta lenses and is configured to operate as a lens with almost no chromatic aberration, thereby implementing a thin optical system having good image quality.
Claims20
A see-through type display apparatus comprising:
- an image projector configured to output image light;
- a waveguide configured to receive the image light output from the image projector and transmit the image light to a user's view, the waveguide comprising a first surface through which the image light is output and a second surface opposite the first surface;
- a first lens disposed on the first surface of the waveguide, the first lens having a negative refractive power, and comprising one or more meta lenses;
- and
- a second lens disposed on the second surface of the waveguide, and the second lens having a positive refractive power,
- the first lens including a first meta lens disposed on the first surface of the waveguide, the first meta lens having a first refractive power;
- and
- a second meta lens disposed on the first surface and spaced apart from the first meta lens by a first distance, the second meta lens having a second refractive power opposite to the first refractive power.
An electronic device comprising:
- a see-through type display apparatus;
- and
- a processor configured to control the see-through type display apparatus to output an additional image that a user views,
- wherein the see-through type display apparatus comprises:
- an image projector configured to output image light;
- a waveguide configured to receive the image light output from the image projector and transmit the image light to a user's view, the waveguide comprising a first surface through which the image light is output and a second surface opposite the first surface;
- a first lens disposed on the first surface of the waveguide, the first lens having a negative refractive power and comprising one or more meta lenses;
- and
- a second lens disposed on the second surface of the waveguide, the second lens and having a positive refractive power,
- the first lens including:
- a first meta lens disposed on the first surface of the waveguide, the first meta lens having a first refractive power;
- and
- a second meta lens disposed on the first surface and spaced apart from the first meta lens by a first distance, the second meta lens having a refractive power opposite to the first meta lens.
