Samsung patents glasses with moving lenses to adjust focus
Samsung describes a wearable device, likely smart glasses, that uses a stack of at least four lenses to project an image to the user's eye. The design allows the first two lenses to slide along the optical axis to change the focus, similar to adjusting the focus on a camera, while the other lenses stay fixed.
In the filing’s own words
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.
What exactly they claim (claim 1)
1. 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, M 12 > 0.99 [ formula 1 ] TTL / ImgH < 1.75 [ formula 2 ] (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).
