Apple filed a patent for Vision Pro's Lens packaging 17 days after WWDC23 that was made public today. It applies to Vision Pro lenses and prescription lenses.
Apple's patent FIG. 1 below shows an exploded view of a packaging assembly including packaging 1 to receive a product, e.g., optical lens(es) 50 and product accessory 60 (e.g., a calibration unit). In some embodiments, packaging 1 may be bundled with product documentation 70 (e.g., instructions for use, warranty and other legal information, etc.), and placed within outer box 80 that may receive packaging 1; Apple's patent FIGS. 3, 4, and 5 show packaging #1 in various stages of opening.
Apple's patent FIG. 9 above shows a partial perspective view of a packaging assembly with optical lenses.
Display With Light Sources And Quantum Dots
Apple has filed a patent that reveals their work on advancing a micro-LED display with quantum dot layers. The new displays could apply to a future version of Vision Pro, smartglasses, an iMac, iPhone, iPad, a gaming device, Apple Watch, computer displays and more. Quantum dot technology could provide sharper resolution, superior contrast and more.
Apple's patent FIG. 10 below illustrates a cross-sectional side view of an illustrative display with quantum dot layers over ultraviolet light sources.

03：Waveguide-Based Displays With Tint Layer
In some operating conditions, such as when an HMD or Smartglasses are operated outdoors, in rooms with bright lighting, or in other environments having relatively high light levels, world light from real-world objects can overpower or wash out virtual objects presented to the devices eye box in image light thereby limiting the contrast and visibility of the virtual objects when viewed at the eye box.
To reduce the brightness of the world light and maximize the contrast of the images (virtual objects) in image light when viewed at the eye box, the optical system may include a light-absorbing layer such as tint layer which may be disposed within the optical path between real-world objects and the output coupler.
The world light from real-world objects may pass through tint layer prior to reaching the eye box (e.g., the tint layer may transmit the world light without transmitting image light). The tint layer may absorb some of the real-world light, thereby reducing its brightness and increasing the contrast of virtual objects in the image light at the eye box.
If desired, the tint layer may also function to absorb real-world light, even when the virtual image is turned off, performing a function like switchable sunglasses.
04：Electronic Devices With Stretchable Fabrics
A head-mounted device may include a main housing portion with displays that display images and optical modules through which the images are viewable from eye boxes. A light seal may be coupled to the main housing portion and may surround the eye boxes to prevent outside light from reaching the viewing area of the head-mounted device. The light seal may include inner and outer fabric layers. The outer fabric layer may be a seamless tube of knit fabric. The inner fabric layer may be an opaque fabric that lines the inner surface of the outer fabric layer. The outer fabric layer may have a modified bird's eye pattern that incorporates alternating knit stitches and tuck stitches. The tuck stitches allow the outer fabric layer to stretch in the lengthwise direction of the fabric to prevent buckling when the light seal is pressed against the user's face.
05: Electronic Devices With Light-Blocking Fabrics
A head-mounted device may include a housing with a display that displays images that are viewable from an eye box. A light seal may be coupled the housing and may block outside light from reaching the eye box. The light seal may include a seamless tube of knit fabric that forms an outermost layer of the light seal. A light-blocking fabric may line the inner surface of the seamless tube of knit fabric. The light-blocking fabric may include a dark-colored weft knit layer facing the eye box, a light-colored weft knit layer facing and matching a color of the seamless tube of knit fabric, and a middle layer joining the light-colored weft knit layer and the dark-colored weft knit layer. The dark-colored weft knit layer may ensure sufficient opacity without being visible through the seamless tube of knit fabric.
