Description

Mobile phone expansion device

Technical Field

The utility model belongs to the technical field of mobile terminal, concretely relates to cell-phone extension device.

Background

At present, screens of mobile phones, especially smart phones, tend to be large, and screens of notebook computers/tablet computers PADs are opposite. Mobile terminals such as mobile phones have higher and higher requirements for processing performance, but the screen size of the mobile terminal is limited due to mobile portability. In quiet reading, demonstration, etc., it is often desirable that the screen be as large as possible, preferably as large as the screen of a laptop/PAD. When the mobile phone is used for communication or walking or carrying, the mobile phone needs to be carried and held conveniently, and the mobile phone is naturally small in size and light in weight. In a common scenario, people often carry both a mobile phone and a laptop/PAD. However, it is difficult to keep the real-time consistency between the data on the mobile phone and the notebook computer/PAD, which is very troublesome.

Two troubles are brought by pursuing a large-screen mobile phone at a time: firstly, it is inconvenient to carry, secondly, easily change into PAD differently, lose the original location of cell-phone. PAD is also becoming smaller for portability, like apple mini PAD, but loses the experience of large screen while increasing portability. The prior art discloses a split mobile terminal, which includes an embedded small mobile phone with a mobile communication function and a mobile terminal host with a network function and a video playing function. Only need use little cell-phone when the conversation, when using network function or video function, combine embedded little cell-phone and mobile terminal host computer: the small mobile phone is made into a size convenient for handheld conversation, and the size of the mobile terminal host is made large, so that better visual experience is provided for users when surfing the internet and watching videos. However, the small mobile phone only has a conversation function, and needs to be combined with a large-size mobile terminal host for use when watching video or surfing the internet, and each mobile phone needs to be specially designed into two parts, so that the matching universality is not easy to maintain.

In order to meet the requirements of portability and large screen, some consumers choose to buy the mobile phone and the PAD at the same time. Some consumers choose to transmit the image of the mobile phone to a projector or a television, but in this case, although a large screen can be provided, the user experiences poor portability.
