Display apparatus and power control method thereof

摘要

A display apparatus and a power control method thereof are provided. The display apparatus includes a power supplying part (40); a Transition Minimized Differential Signaling (TMDS) receiving part (10) which decodes a TMDS signal input from an external signal source; a controller (70) which controls the power supplying part (40) to supply driving power to the TMDS receiving part (10) when a clock signal of the TMDS signal is received. The power control method includes cutting off driving power to a Transition Minimized Differential Signaling (TMDS) receiving part (10) when the display apparatus enters a power-saving mode; determining whether a clock signal is detected in a TMDS signal; and supplying driving power to the TMDS receiving part (10) if it is determined that the clock signal is detected.
