详细描述

A normal laptop has what we call a front lid.

If the laptop can be converted to a tablet by rotating or closing the lid where the display is out, this is known as a back lid.

QLidReading Units

The Lid sensor can detect if a device's lid is closed or not. A lid can be a laptop, a laptop that converts to a tablet, or even a cover for a tablet or phone.
