  • Patent number: 11249517
    Abstract: An electronic apparatus and its screen control method adapted to an electronic apparatus are provided. The electronic apparatus includes a first display screen, a second display screen, and a body. The first display screen is pivotally connected to the body along a first rotation axis, and the second display screen is disposed on an upper surface of the body. The method includes following steps. A sight of a user is detected by a sight sensor. In response to the sight projected on the second display screen at a default position, a screen rotation degree is determined according to a direction of the sight. According to the screen rotation degree, the second display screen is controlled to rotate from the default position along the second rotation axis to a display position, so that a view angle at which the user watches the second display screen satisfies a predetermined condition.
