Apple Receives Patent for Lenticular Lens Display Technology. – Display Daily

The patent (WO2021252532) is titled “Lenticular Lens and Methods for Producing the Same.” It describes a lenticular lens and the methods used to produce it. Lenticular lenses are optical devices with an array of small, elongated lenses on one surface, which create different images or visual effects depending on the viewing angle.

The lenticular lens disclosed in this patent has a plurality of lenticules (small lens elements) arranged in a predetermined pattern on one surface, while the other surface is a substrate or flat base. The lenticules are designed to have a specific orientation, allowing them to create different images or visual effects depending on the angle from which they are viewed.

One aspect of this patent is the method of producing such a lenticular lens. It involves:

The potential use cases, as outlined in the document, are myriad. However, the patent uses the term head-mounted displays (HMDs) a lot. Most of the discussion is around various design aspects and production methods for creating lenticular lenses, which can be tailored specifically for use in HMDs. That would be the main reason that it has attracted some notice among the numerous social media accounts that follow Apple religiously.

“In various embodiments, the lenticular lenses described herein may be used in, for example, displays, signage, packaging materials, image sensors, optical filters, or other optical applications where the quality of the image or the user experience is improved by the presence of the lenticular lens.”

Lenticular lenses have also been used in display devices to provide 3D and autostereoscopic experiences without the need for special glasses.Apple had previously received a patent for a lenticular display that tracked multiple users and what they saw, we covered the story back in 2021. In the meantime, are some examples of actual displays incorporating lenticular lenses:

Apple has sufficient legal power and money to patent even the most trivial of applications or technologies. You cannot read anything into these patents other than the fact that the company obviously sees value in the technology and work it has done on it, and that it may be relevant in a broader context and as part of other work going on in the company.
