摘要： A display apparatus and a control method thereof are disclosed. The display apparatus includes a signal processor which processes a video signal; a display which displays an image based on the video signal processed by the signal processor, a light source providing light for displaying the image; and a driving circuit which drives the light source on the basis of a dimming signal having an on-section and an off-section for dimming the light source. The driving circuit includes a protection circuit for performing a protection operation as a result of an abnormal electric current flowing in the light source during the off-section. The display apparatus is protected when a short circuit occurs between the light source and the driving circuit, thereby enhancing the stability and reliability of the apparatus.

摘要： A display apparatus and a power supplying method are provided. The display apparatus includes a signal receiver which receives a video signal; a signal processor which processes the video signal; a display unit which displays an image based on a video signal processed by the signal processor; and a power supply which converts an alternating current (AC) voltage into a direct current (DC) voltage and supplies an operation voltage to the display unit, the power supply including: a power factor correction (PFC) unit which adjusts the DC voltage and corrects a power factor of the power supply; a detector which detects a plurality of voltages in the power supply and outputs a common detection signal indicating whether at least one of the plurality of voltages is abnormal; and a controller which receives the common detection signal, and controls the PFC unit based on the common detection signal.
