    Abstract: Disclosed herein are a power converting apparatus and a home appliance having the same. The power converting apparatus according to an embodiment of the present invention includes an inverter having a plurality of upper switching devices and a plurality of lower switching devices, a plurality of upper gate drivers to output a gate drive signal to each of gate terminals of the plurality of upper switching devices, and a plurality of upper ON resistors disposed between the plurality of upper switching devices and the plurality of upper gate drivers, wherein resistance values of the upper ON resistors are different from each other. Thus, electromagnetic interference noise generated when the inverter is turned on or off may be attenuated without changing the switching frequency.

    Abstract: Disclosed are a signal processing device and an image display apparatus including the same. The signal processing device of an embodiment of the present disclosure includes: a quality calculator configured to calculate an source quality of an image signal received from an external settop box or a network; an image quality setter configured to set an image quality of the image signal based on the calculated source quality; and an image quality processor configured to perform image quality processing on the image signal based on the set image quality, wherein in response to the source quality of the received image signal being changed at a first time point, the image quality setter changes an image quality setting sequentially from a first setting to a second setting; and based on the image quality setting, the image quality processor performs image quality processing. Accordingly, flicker may be reduced when an image quality is changed due to a change in the source quality of the received image signal.
