Abstract
Provided are an optical assembly and an electronic apparatus having the optical assembly. The optical assembly includes at least one reflective mirror reflecting image light output form a display module, a refractive lens through which image light reflected from the at least one reflective mirror passes, and a reflective lens having a first surface and a second surface and including a transflective coating layer provided on the first surface and reflecting the image light that passed through the refractive lens in a first direction and transmitting real light from a second direction facing the first direction.
Claims14
An optical assembly comprising:
- a first reflective mirror configured to reflect image light output from a display module;
- a second reflective mirror configured to reflect the image light reflected from the first reflective mirror;
- a refractive lens configured to allow the image light reflected from the second reflective mirror to pass therethrough;
- and
- a reflective lens having a first surface and a second surface, each of the first surface and the second surface having an asymmetrical aspherical shape, and the reflective lens including a transflective coating layer provided on the first surface and configured to reflect the image light that passed through the refractive lens in a first direction and to transmit real light from a second direction facing the first direction,
- wherein a straight distance T3 between a center of an entrance pupil and a center of the display module of the optical assembly is in a range that 27 mm<T3<35 mm.
An optical assembly comprising:
- a first reflective mirror configured to reflect image light output from a display module;
- a second reflective mirror configured to reflect the image light reflected from the first reflective mirror;
- a refractive lens configured to allow the image light reflected from the second reflective mirror to pass therethrough;
- and
- a reflective lens having a first surface and a second surface, each of the first surface and the second surface having an asymmetrical aspherical shape, and the reflective lens including a transflective coating laver provided on the first surface and configured to reflect the image light that passed through the refractive lens in a first direction and to transmit real light from a second direction facing the first direction,
- satisfying a following inequality:
- 1.8<(M1EFY)/EFY<2.2, <Inequality>
- wherein M1EFY denotes a focal length of the first reflective mirror, and EFY denotes a focal length in Y-axis of the optical assembly.
An electronic apparatus comprising:
- a housing;
- a display module mounted on one surface of the housing;
- a first reflective mirror configured to reflect image light output from the display module and arranged to face the display module;
- a second reflective mirror configured to reflect the image light reflected from the first reflective mirror and arranged below the display module;
- a refractive lens arranged to allow the image light reflected from the second reflective mirror to pass therethrough;
- and
- a reflective lens configured to reflect the image light that passed through the refractive lens in a user's eye direction and having a transflective coating layer configured to transmit external real light, wherein one or more of both surfaces have an asymmetrical aspherical shape,
- wherein the refractive lens is arranged from a lower end portion of the first reflective mirror to a lower end portion of the second reflective mirror, and the reflective lens is arranged below the refractive lens.
