Samsung Electro-Mechanics will be excluded from Apple’s supply chain for folded zoom camera modules for iPhones launching in 2023, TheElec has learned.

Folded zoom uses prism to bend the light before it reaches the image sensor __ it is a sort of periscope-like telephoto camera.

The technology allows camera modules to be made thinner that allows them to not stick out on the back covers of smartphones.

Samsung had used Samsung Electro-Mechanics’ folded zoom technology for the Galaxy S20 Ultra for the first time.

Apple is planning to apply the technology for iPhones launching in 2023, but patents are getting in its way.

Samsung Electronics had secured the patents needed for the technology by acquiring Israel-based Corephotonix in 2019.

Samsung Electro-Mechanics and Jahwa Electronics, which are part of Samsung’s supply chain, also owns patents related to actuators used in folded zoom lens barrels.

Samsung Electro-Mechanics uses a ball guide actuator to move the lens barrel. This is considered more advanced than spring actuators that Apple is currently using on the cameras for its iPhones.

Folded zoom can accommodate more lens and larger image sensors, which requires precise control of them which ball guide method is more advantageous in.

Apple was expected to secure supply of the folded zoom modules from  its long-time supplier LG InnoTek while procuring the ball guide actuators from Samsung Electro-Mechanics.

If Cupertino have chosen this rout, it would have replaced its actuator partners Alps Electric and Mitsumi Electric with Samsung Electro-Mechanics.

Meanwhile, Apple reviewed Jahwa Electronics’ optical image stabilization module factory during the first half of the year.

OIS are conventionally integrated with autofocus actuator to form one module. The  integrated module is Jahwa’s main product. Combining it with an image sensor and a board completes a camera module.

However, Jahwa co-developed the OIS technology with Samsung and Samsung Electro-Mechanics, raising concerns that it may not be able to supply them to Apple.

However, Apple seems positioned to procure OIS from Jahwa, while it will looking for alternative ways to handle the patent problem this poses.

Cupertino likely has its own workaround for the patents or will pay licensing fee to Samsung.

For Apple to adopt folded zoom for iPhones in 2023, it needs to finalize the specs and suppliers within this year. LG InnoTek is currently developing its own folded zoom technology.

LG InnoTek and Corephotonix are embroiled in a lpatent infringement lawsuit, but the former has successfully nullified the latter’s telephoto lens patent in South Korea in July through the local patent board. LG InnoTek also won the lawsuit at the local patent court last month.
