The iPhone 20’s quad-curved display will be Apple’s most challenging task yet, but the company’s trillion-dollar status wasn’t achieved by taking a backseat when facing adversity. However, that doesn’t mean the California-based giant won’t face problems with this design, as a new report highlights a flaw that may not be addressed next year, when Apple’s 20th-anniversary launch takes place.

The materials used for the iPhone 20’s quad-curved design carry a distortion risk at the edges that can decrease the panel’s overall brightness

The technical aspect of the flaw has been highlighted by Korean technology media outlet ETNews, stating that the display cathode layer is made of a magnesium-silver alloy that risks distortion at the screen’s edges, resulting in a brightness reduction. Apple will likely view this flaw as a blemish to the iPhone 20’s entire design, which is why the report mentions that the Cupertino firm will replace the magnesium-silver alloy with Indium-Zinc Oxide (IZO).

Unfortunately, don’t expect the iPhone 20 to be treated to this change next year because Apple is expected to implement it in 2028, with Samsung and LG closely working with its customer to address this issue. Interestingly, LG wasn’t mentioned as a supply chain partner for Apple’s iPhone 20 as the company reportedly formed an exclusive partnership with Samsung.

Having a single manufacturer will raise the quad-curved display’s price, which is why LG could be added to the supplier list in 2028. The Korean display manufacturer will inject around 1.106 trillion won (approximately $741.29 million) into the construction and operation of a new facility.

The IZO cathode layer is expected to be mass produced at one of LG’s new facilities, with Samsung also aiming towards building these manufacturing plants to keep up with Apple’s demand. So far, this display’s cost hasn’t been mentioned in previous or newer reports, but the quad-curved design won’t be easy to implement, meaning that the iPhone 20 could reach a new price plateau, becoming the most expensive release in Apple’s history.

The worst-case scenario is that Apple pulls the plug on this display’s development, with the iPhone 20 shipping with a regular panel with flat edges. Since 2028 is the alleged year when the refined quad-curved display will enter mass production, there’s a strong possibility that Apple will delay this technology until the distortion flaw is fully addressed.
