A Weibo tipster known as Smart Pikachu has shared details about the rear display on the upcoming Xiaomi 18 Pro models.
According to the leak, the device will feature a 4-inch rear screen, a significant increase from the 2.7-inch panel found on the Xiaomi 17 Pro.
The tipster claims the display will offer high brightness, high pixel density (PPI), large rounded corners, and built-in privacy protection.
If accurate, this would represent a clear evolution from the previous generation.
The Xiaomi 17 Pro's rear display measured 2.7 inches with a resolution of 572 × 904 pixels, a 120Hz refresh rate, and a peak brightness of 3,500 nits.
A 4-inch panel would provide much more space for features already introduced on the current model, including live translation, teleprompter mode, and interactive widgets.
Xiaomi is reportedly evolving the rear display into an AI-powered smart window, enabling more dynamic and context-aware interactions.
A larger, brighter display with improved color accuracy would make that vision more practical.
The Xiaomi 18 series is expected to launch in September, so official confirmation of its hardware specifications is still pending.
