Mobile display device, mobile display system and image signal reproducing method thereof
First Claim
1. A mobile display device for communicating with a host computer in wired and wireless manners depending upon whether the mobile display device is coupled with a docking station that is supplied with one of a wired input signal and a wireless input signal from the host computer, comprising:
- a wired module that receives the one of the wired input signal and the wireless input signal, applied from the docking station and converting the one of the wired input signal and the wireless input signal into a first video signal when the mobile display device is coupled with the docking station;
a wireless module that converts the one of the wired input signal and the wireless input signal, applied from the host computer into a second video signal when the mobile display device is released from the docking station;
a display panel that reproduces the first video signal and the second video signal; and
a display controller that converts, within a predetermined time margin, the first and second video signals applied to the display panel from the wired module and the wireless module, depending upon whether the mobile display device is coupled with the docking station, and applying to the display panel a control signal for turning on and off images reproduced from the display panel at the time of the conversions.

5. A mobile display system, comprising:
-
a host computer that enables wired and wireless communications; a docking station provided with a wired module for receiving one of a wired input signal and a wireless input signal from the host computer and converting the one of the wired input signal and the wireless input signal into a first video signal; and a mobile display device that converts, within a predetermined time margin, said one of the wired input signal and the wireless input signal applied from the host computer into a second video signal, and reproducing either of the first and second video signal depending upon whether the mobile display device is coupled with the docking station, wherein the mobile display device comprises; a display panel that reproduces the first and second video signals; coupling connectors that couple the mobile display device with the docking station; a wireless module that converts said one of the wired input signal and the wireless input signal into the second video signal; a switching part that selects and applies either of the first and second video signals to the display panel; and a display controller that controls the switching part depending upon the coupled state of the coupling connectors, and applies either of the first and second video signals to the display panel. - View Dependent Claims (6, 7)

8. An image signal reproducing method of a mobile display device for communicating with a host computer in wired and wireless manners depending upon whether the mobile display device is coupled with a docking station supplied with one of a wired input signal and a wireless input signal from the host computer, the method comprising the steps of:
-
selectively performing one of a wired communication and a wireless communication depending on whether the mobile display device is coupled with the docking station; and converting the wired communication to the wireless communication, and vice versa, within a predetermined time margin, according to a docking state of the mobile display device to the docking station, wherein, when the wired communication is converted to the wireless communication, and vice versa, a video signal based on one of a wired communication state and wireless communication state prior to said conversion is received and reproduced for a predetermined time.
