Apple's new patent revealed: exploring innovative liquid lens technology for head-mounted devices

Apple recently announced a new patent, showing that they are actively advancing the development of head-mounted device technology. This patent involves a technological innovation called "electronic device with liquid lens"

According to the patent content, this electronic device is equipped with a special lens that allows users to view images through a head-mounted device. Most notably, these lenses are tunable liquid lenses, each containing a lens chamber with rigid or flexible walls to form the optical lens surface. In addition, these lenses are equipped with actuator, pump and reservoir systems that can change the shape of the lens in response to control signals to achieve tuning of the lens. The lens chamber of each liquid lens is filled with oil or other liquids, and the refractive index of the lens can be adjusted using inorganic dielectric particles or other refractive index adjusting particles, and the size of these particles can reach sub-wavelength levels

According to my understanding, this new patent is likely to support Apple’s latest head-mounted display device-Vision Pro. Vision Pro was first released on June 6, 2023, equipped with two micro OLED screens with a total of 23 million pixels, supporting 4K wide color gamut video and HDR technology. This headset is also equipped with Apple's M2 chip and the R1 chip specially designed for Vision Pro, and users can operate it through gestures, eyes or voice. In addition, Vision Pro is also equipped with the VisionOS system and has a new built-in App Store, allowing users to use hundreds of thousands of iPhone or iPad applications. In addition, it also supports 3D camera function, users can shoot 3D images with spatial audio

Apple has been constantly innovating and improving its head-mounted device technology, and the publication of this new patent shows that they are working on Provide a more advanced head-mounted display device experience and bring more possibilities to users. This also indicates that head-mounted technology will play a more important role in future development
