Problems solved by technology
Also, the disadvantage of using legacy video interfaces is that the device can be connected to different legacy display devices, but each of these legacy interfaces specifies the signal to be used (and therefore, the power required to generate that signal)
However, a dedicated video interface may require its own dedicated monitor with its own dedicated video input interface
This solution has the great drawback that the manufacturer has to supply the display device with an additional new dedicated connector and signal processing unit, which may only be produced in small quantities

The present invention relates to the field of mobile terminal devices, dongles and display device connected with external displays for mobile terminals. A mobile terminal device comprises a processing unit having the capability to process high resolution display content, a user interface comprising at least a low resolution display, connected to said processing unit to display low resolution display contents, and a video display interface connected to said processing unit, said display interface having high resolution display contents transferring capabilities to provide said high resolution display contents from said processing unit, wherein said mobile terminal device comprises high resolution display contents compression capabilities to reduce the data rate of said high resolution display contents, and a serial bus connector to transfer said high resolution display contents having a reduced data rate to an external display device. The invention also relates to other embodiments of this device, a connectable display and a display adapter to connect a conventional display to the mobile terminal.
Description
technical field [0001] The invention relates to the field of mobile terminal devices and external display devices used in conjunction with mobile terminals. The invention also relates to the following technical fields: mobile telephones, video signal conversion and displays connectable to mobile terminal equipment. The invention also relates to enhancing the display interface of a mobile device with as little use of proprietary interface technology as possible. The invention also relates to a plug-in capable of allowing a large display to be used with a mobile terminal without using a conventional display interface in the mobile terminal device. The invention also relates to video display interface technology for quasi-static images used eg in PC office or animated video / movie based collages. Background technique [0002] Currently, it is not possible to combine small mobile devices such as mobile phones and player devices with large displays because the overall size of su...
