摘要：In a video apparatus having a display module, the electric field strength orautomatic gain control (AGC) signal is recognized from a received broadcast signal and apower supply mode of the display module is controlled according to the level of therecognized AGC signal, to prevent overheating of the display module without using anadditional device when a weak signal or noise is being received. The video apparatusincludes a display module for displaying a broadcast signal received via a broadcastchannel, the display module being selectively driven according to one of a plurality ofpower supply modes; and a controller for controllably setting the power supply mode ofthe display module according to the strength of an electric field of the receivedbroadcast signal, the controller maintaining the set power supply mode if the electricfield strength lies between lower and upper thresholds defining a threshold region.
