Description

Portable electronic device with multiple screens

technical field

The invention relates to a portable electronic device, in particular to a portable electronic device with multiple screens.

Background technique

Portable electronic devices such as palmtop computers, laptop computers, notebook computers, personal computer tablets, and personal digital assistants (PDAs) have become more and more common. In order to provide users with more diversified operation and viewing modes, a portable electronic device with multiple screens has been proposed. Most of the existing portable electronic devices with multiple screens are pivotally connected to each other through a link structure, so that any two screens are suitable for relative rotation and maintain an opening and closing angle.

However, the link structure often causes a significant step difference between the main screen and the secondary screen of the portable electronic device with multiple screens, resulting in poor visual effects and damaging the aesthetic appearance of the product. Moreover, the structure of the connecting rods connecting multiple screens is often complicated, which makes the user's operation inconvenient, so that the portable electronic device with multiple screens cannot provide a good user experience.

Accordingly, how to make a portable electronic device with multiple screens overcome the step difference between the main screen and the secondary screen to improve the overall aesthetics, and at the same time have good operational flexibility and user experience is a problem that relevant technical personnel need to think about and solve.

Contents of the invention

The invention is directed to a portable electronic device with multiple screens, which compensates for the step difference when the second screen moves out of the first screen through a lifting mechanism, thereby having good operational flexibility and overall aesthetics.

According to an embodiment of the present invention, the portable electronic device with multiple screens includes a first screen and a second screen. The second screen is movably coupled to the first screen along an arc-shaped path, so as to be accommodated in the first screen or moved out of the first screen. The display surface of the first screen and the display surface of the second screen face the same direction. The second screen includes a base, a lifting mechanism, and a display unit. The lifting mechanism is arranged on the base. The display unit is arranged on the lifting mechanism to be driven by the lifting mechanism to rise or fall relative to the base. When the second screen moves out of the first screen and there is a level difference between the display surface of the display unit and the display surface of the first screen, the display unit is adapted to be lifted relative to the base by the lifting mechanism to compensate for the level difference.

Based on the above, in addition to the second screen of the portable electronic device with multiple screens of the present invention being movably coupled to the first screen to be accommodated in the first screen or moved out of the first screen, the second screen can also be lifted or lowered by the lifting mechanism to drive the display unit on the lifting mechanism to lift or lower relative to the base. Accordingly, when the second screen moves out of the first screen and there is a level difference between the display surface of the display unit and the display surface of the first screen, the display unit is adapted to be lifted relative to the base through the lifting mechanism to compensate for the level difference, so that the portable electronic device with multiple screens has good operational flexibility and overall aesthetics, and allows users to have better visual effects when operating the portable electronic device with multiple screens.
