Power supply having reference and compensation voltages and display apparatus including the same

Abstract

A display apparatus includes a display panel configured to display an image, a timing controller configured to control the display panel, and a power supply including an output circuit configured to generate an output power for supplying power to the display panel based on an input power, and an output controller configured to sense a voltage output through an output terminal of the output circuit to obtain a sensing value. The output controller provides a reference voltage value and compensation voltage values having levels which differ from a level of the reference voltage value, based on an external signal. Further, the output controller selectively outputs at least one of the reference voltage value and the compensation voltage values to provide a voltage value, based on the external signal, and generates a control signal for controlling the output circuit, based on the sensing value and the voltage value.
