The invention discloses a device and a method for sharing an interface, and a mobile communication terminal. The device comprises a control unit, a video processing unit, a switch unit, a detection control unit and a multiplex interface, wherein the detection control unit is used for detecting first voltage from the multiplex interface, comparing the first voltage with a preset voltage value, controlling the switch unit to ensure that the video processing unit is connected with the multiplex interface through the switch unit if the first voltage is more than 0 and less than or equal to the preset voltage value, and controlling the switch unit to ensure that the control unit is connected with the multiplex interface through the switch unit if the first voltage is equal to 0 or more than the preset voltage value. Through the mode, multiple functions can be realized through one multiplex interface, the size of the interface is reduced, cost is reduced, the device is conveniently operated and used by a user, and the user experience is improved.
Description
technical field [0001] The invention relates to the field of shared interfaces, in particular to a device and method for sharing interfaces, and a mobile communication terminal. Background technique [0002] Currently, mobile communication terminals, such as tablet computers, are more and more widely used in people's daily life. In order to realize as many functions as possible to satisfy different demands of users, various functional interfaces exist simultaneously on the hardware of the mobile communication terminal. For example, a power supply or charging interface, a USB interface, and an HDMI (High Definition Multimedia Interface, High Definition Multimedia Interface) interface for outputting high-definition signals. [0003] see figure 1 , figure 1 It is a structural schematic diagram of a mobile communication terminal in the prior art. Such as figure 1 As shown, the mobile communication terminal 10 in the prior art includes a central processing unit 11 , an HDMI ...
