ABSTRACT:
A display apparatus comprises input parts through which analog and digital video signals outputted from a video card are inputted, and a plurality of driving components. The apparatus further comprises: an electric power supply part for supplying electric power; a scaler chip including an A/D converter and PLL and a TMDS part for processing an analog video signal and a digital video signal, respectively; and a controller for detecting horizontal and vertical synchronous signals decoded by the TMDS part of the scaler chip, and for lowering the number of driving clocks of the scaler chip and turning off the driving components according to determination of a power saving mode when at least one of the horizontal and vertical synchronous signals is not outputted. With this configuration, electric power consumption is effectively minimized in a power saving mode in a display apparatus having a unified scaler chip.
