The South Korean tech leak account yeux1122 revealed that Apple is specifically fine-tuning the display controller integrated circuit (DDI) used in the first foldable iPhone, with the goal of achieving a thinner overall design.

DDI is a crucial component that converts digital signals from the device's processor into the analog signals needed to control the pixels on the display.

Accordingly, improvements to DDI could allow for thinner panel assemblies, reduced heat dissipation, and lower power consumption. These are crucial improvements for compact devices like foldable smartphones.

Furthermore, numerous sources, including analysts Ming-Chi Kuo and Jeff Pu, as well as supply chain leak expert Digital Chat Station on Weibo, now suggest that the foldable iPhone will have a 7.8-inch main screen when unfolded and a 5.5-inch secondary screen. This consistency in details indicates that Apple may have finalized key aspects of the device's hardware.

Previously, yeux1122, citing sources within Apple's supply chain, revealed that Apple was in the final stages of selecting a key supplier for its next-generation foldable display technology.

Specifically, according to the report, Apple has maintained stringent technical requirements for potential suppliers, focusing on upholding current leading standards for thickness, dimensions, and radius of curvature.

Analyst Ming-Chi Kuo previously stated that Apple's foldable iPhone is still in the planning stages, with analysts predicting the product could launch sometime between late 2025 and 2027.
