Abstract
According to an embodiments, an wearable electronic device comprises: at least four lenses arranged along an optical axis from a user's eye-side to a display, the at least four lenses including a first lens and a second lens; wherein the first lens is closest to the user's eye-side of the at least four lenses and includes at least one flat surface, and a first quarter wave plate (QWP) and a first refractive member disposed on the at least one flat surface, wherein the second lens from the user's eye-side includes at least one convex surface and a second refractive member disposed on the at least one convex surface.
Claims19
A wearable electronic device comprising:
- a display comprising at least one display member;
- at least four lenses arranged along an optical axis from a user's eye-side to the display, the at least four lenses including a first lens and a second lens disposed in the order farthest from the display;
- wherein the first lens includes at least one flat surface, and a first quarter wave plate and a first refractive member disposed on the at least one flat surface,
- wherein the second lens includes at least one convex surface and a second refractive member disposed on the at least one convex surface,
- wherein the first lens and the second lens are configured to move in an optical axis direction to enable diopter adjustment, and a third lens and a fourth lens are fixed during diopter adjustment, and
- wherein the wearable electronic device satisfies formula 1 and formula 2 as set forth below,

- (wherein M12 in formula 1 is a combined group magnification of the first lens and second lens, TTL in formula 2 is a “total top length”, indicating a distance between an eye-side surface of the first lens and the display, and ImgH in formula 2 is a maximum image height of the display).
A wearable electronic device comprising:
- a display comprising at least one display member:
- a first lens, a second lens, a third lens, and a fourth lens sequentially arranged along an optical axis direction from a user's eye-side to the display;
- wherein the first lens includes a substantially flat surface laminated with a first quarter wave plate and a reflective polarizer on the substantially flat surface,
- wherein the second lens includes at least one convex surface having a beam splitter formed thereon,
- wherein a second quarter wave plate and a polarizer are formed on a display-side surface of the fourth lens,
- wherein the first lens and the second lens are configured to move on an optical axis direction to enable diopter adjustment,
- wherein the third lens and the fourth lens are fixed during diopter adjustment, and
- wherein the wearable electronic device satisfies formula 1 and formula 2 as set forth below,
