DISPLAY DEVICE, A HOST DEVICE, A DISPLAY SYSTEM AND A CONTROL METHOD FOR IMPLEMENTING A POWER SAVING MODE OF THE HOST DEVICE CORRESPONDING TO CONVERSION OF AN INPUT SOURCE

摘要

PURPOSE: A display device, a host device, a display system and a control method are provided to automatically convert PC power unnecessary for conversion into a power saving mode, thereby reducing consumption power.;CONSTITUTION: A communication interface unit(140) communicates with a host device. A signal generation unit(150) generates signals for converting the host device into an power saving state. When an input source outputted through the display unit is converted into other input source in the host device, a control unit(170) transmits the signals to the host device.;COPYRIGHT KIPO 2013;[Reference numerals] (110) Image input unit; (120) Image processing unit; (130) Display unit; (140) Communication interface unit; (150) Signal generation unit; (160) User interface unit; (170) Control unit
