Description
Technical field
The utility model relates to consumer electronics fields, and in particular to a kind of device for supporting mobile phone and PC to switch.
Background technique
Early in the epoch of the initial rudiment of smart phone, just there is manufacturer to have found another demand of smart phone: can lead to
It crosses and is broadened into large screen equipment as similar PC, to preferably complete work.Compared to smart phone, that is slight after all
Screen, 10 cun or more of PC screen and key mouse input mode easily, so that PC is free from controversy as the king of office efficiency.Institute
With in 2007, Palm company just released the first hardware product that mobile phone is extended to PC: Palm Foleo.
Current year remains unchanged Windows=PC=efficiency epoch, a likeness in form laptop, but that run is Linux
System and positioning are that the extension companion of mobile phone is not received by the market eventually, as a result also such as market expectations, Palm Foleo
It does not sell formally finally.Then many producers have all attempted similar idea, and the giants such as Samsung, Microsoft also joined this row
Column, are proposed the product for being suitble to respective company technique route.Industry also proposed various specifications, to support this imagination.USB
OTG and MHL is exactly two specifications therein.USB OTG has already appeared in 2.0 epoch of USB, it solves do not having USB Host
In the case where, the problem of two equipment rooms carry out data transmission.MHL is then a kind of mobile terminal high-definition audio and video standard interface, is
A kind of audio-visual standard interface connecting portable consumer electronic device.Generally speaking, the two specifications allow mobile phone direct
Use the keyboard and mouse and display of PC.Driving built in Android also starts directly to support above-mentioned specification.More and more
Mobile phone, can by directly by docking station in a manner of use PC display.By taking Huawei honor Note10 as an example, as it is a across
The large-size screen monitors flagship on boundary, " PC mode " are also added to wherein.The PC mode connection of Note10 is more succinct, selects Type-C To
HDMI wire is directly connected to mobile phone and display that can enter PC mode.
