摘要： White noise images and white noise-like pattern images are discerned by making use of the fact that the address current is increased when such an image is entered and detecting the address current by an address current detection circuit. When the detected address current exceeds a given value α and persists for a given period of time, a CPU controls a contrast control circuit to lower the contrast of the video signal, thus reducing the power consumption of an address driver circuit.

摘要： It is an object of the present invention to provide an image display apparatus which enables cost reduction while being free from electromagnetic interference problems.A power supply circuit comprises, on a single circuit board, an AC inlet to which a power cord is connected from an external AC power supply, a filter circuit to which an inductance element is connected to suppress leakage of electromagnetic waves to the outside of the image display apparatus, and a switch which switches on/off an AC output supplied from the filter circuit. The circuit board of the power supply circuit is entirely covered by electromagnetic shielding means to shield electromagnetic waves. The electromagnetic shielding means is composed of, for example, a first shielding section which surrounds the lateral side of the circuit board and a second shielding section which covers the upper side of the circuit board. The second shielding section is formed of a part of the flat section of a rear cover of the image display apparatus.

摘要： The present invention improves the reliability of a display apparatus by suppressing the temperature rise of the display apparatus mounted on a wall. The display apparatus is provided with a wall mount switch to detect a wall mount member if the wall mount member is attached to the rear of the display apparatus. If it is detected by the wall mount switch that the display apparatus is mounted on a wall, the display power supplied to a display unit is set lower than normal by a power controller. This suppresses the temperature rise of the apparatus mounted on a wall.
