The prevent invention relates to a display apparatus having a display main body adapted to display a picture, a base part adapted to be mounted on an installation surface and supporting the display main body, and a stand part disposed between the base part and the display main body. A first hinge part is disposed between the display main body and the stand part to fold the stand part onto a rear of the display main body. A second hinge part is disposed between the stand part and the base part to rotate the base part between a supporting position where the base part is mounted in a substantially transverse direction with respect to the display main body and a folding position where the base part is mounted substantially parallel to a first end of the stand part. A locking assembly prevents and allows the base part from being and to be rotated between the supporting position and the folding position.

A bias circuit for a smart power amplifier includes a high power mode bias circuit and a low power mode bias circuit, and operates only one of the bias circuits selectively using a switching circuit according to an input signal. Therefore, the bias circuit of high power mode and the bias circuit of the low power mode are divided and can be optimized according to characteristics of the power. Accordingly, a gain difference with respect to each power can be minimized and the low power mode can be controlled with a small amount of current in a state of initial current with a low power and in a middle power, such that an efficiency of the power amplifier can be improved at low power.
