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.
