DISPLAY APPARATUS AND POWER CIRCUIT APPARATUS

摘要

PURPOSE: A display apparatus and a power circuit apparatus thereof are provided to minimize power consumption in a feedback circuit for stabilizing operation voltage by including a feedback part and a rectification flattening part. CONSTITUTION: A switching part(T1,Q1) performs a switching operation. A rectification flattening part(D1,C1) flattens and rectifies output voltage of the switching part in order to provide operation voltage. A display apparatus is operated by receiving the operation voltage. A control circuit part(CONT) controls the switching part. A feedback part(161) receives a bias current by the output voltage of the switching part. The feedback part provides a feedback signal to the control circuit part.
