Apple is prototyping a second new iPhone display, this one measuring around 6.4 inches, that could be destined for the 20th anniversary iPhone, according to Chinese leaker Digital Chat Station. The leaker claims Apple is sampling two new display panels: one at 6.4 inches for the "iPhone 20 Pro" and another at approximately 7 inches for the "iPhone 20 Pro Max".

The devices may adopt an all-new borderless design with curves on all four edges, aligning with earlier reports of edge-to-edge displays with curved glass. A 6.4-inch screen would be a modest increase from the current iPhone 17 Pro's 6.3-inch display.

Apple’s 20th anniversary models are also expected to feature under-display Face ID, a custom Apple image sensor, haptic buttons, the A21 chip, higher bandwidth memory, and a pure silicon battery. These rumors follow a Bloomberg report about Apple’s development of two size options for the anniversary lineup.
