Samsung is still deciding whether to go ahead with committing to new, dedicated factory lines.\u00a0<\/p>\n<p>However, Apple isn\u2019t waiting for either of them to make up their minds; it needs the display done. Unlike the flat OLED panels that the company has used on iPhones since 2020, the <a href=\"https:\/\/www.digitaltrends.com\/phones\/the-iphones-return-to-curved-screens-could-be-a-clever-trick-without-sloping-glass\/\" rel=\"nofollow noopener\" target=\"_blank\">company wants a four-sided bending display that curves on all four edges<\/a> simultaneously.\u00a0<\/p>\n<p>Apple wants the display for the \u201call-screen\u201d iPhone that it has been reportedly building for years. However, the problem is optical distortion at the curved edges, which compounds even more when all four sides are bending at once.\u00a0<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" width=\"2000\" height=\"1200\" data-wp-class--hide=\"state.isContentHidden\" data-wp-class--show=\"state.isContentVisible\" data-wp-init=\"callbacks.setButtonStyles\" data-wp-on-async--click=\"actions.showLightbox\" data-wp-on-async--load=\"callbacks.setButtonStyles\" data-wp-on-async-window--resize=\"callbacks.setButtonStyles\" src=\"https:\/\/www.europesays.com\/korea\/wp-content\/uploads\/2026\/05\/iPhone-Air-Featured.jpg\" alt=\"iPhone Air Featured\" class=\"wp-image-5970566\"  \/><\/p>\n<p>\t\tRachit Agarwal \/ Digital Trends<\/p>\n<p>How is Apple planning to fix the curved display\u2019s biggest problem?<\/p>\n<p>The fix that Apple proposes is IZO cathodes, which, unlike the cathodes in OLED panels on regular smartphones, are more transparent and therefore allow more light to pass through. A more transparent cathode means less distortion at the curved edges, cleaner image quality, and a display that doesn\u2019t look distorted at the edges.\u00a0<\/p>\n<p>The catch, however, is that manufacturing IZO cathodes requires specialized low-damage TCO sputtering equipment that current OLED lines aren\u2019t equipped to handle, especially at scale. I know what you\u2019re thinking. Samsung already featured curved displays on the Galaxy S series. Several Android manufacturers also provide slightly curved displays, even on midrange phones.\u00a0<\/p>\n<p>However, what Apple isn\u2019t doing is simply copying that playbook. The IZO cathode push signals that the company isn\u2019t shipping a curved display until it perfects the technology, which, by the way, is a well-known problem on the mid-range Android smartphones I was talking about.\u00a0<\/p>\n<p>What puzzles me, however, is that the company is working on a four-sided bending display for the <a href=\"https:\/\/www.digitaltrends.com\/phones\/apples-iphone-20-may-finally-ditch-the-design-weve-known-for-years\/\" rel=\"nofollow noopener\" target=\"_blank\">2027 anniversary iPhone<\/a>, but the IZO cathode technology won\u2019t arrive until the 2028 model.\u00a0<\/p>\n<p>Does this mean that the 20th anniversary iPhone will ship without the improved curved display? Sounds like it, but we shouldn\u2019t forget that Apple never ships a product unless it thinks it has perfected it. <\/p>\n","protected":false},"excerpt":{"rendered":"Apple doesn\u2019t ask its suppliers to build things.
