Abstract
A display apparatus includes a display panel including a plurality of pixels, a timing controller configured to generate current control information on the basis of a degree of transition of image data which is to be applied to a corresponding pixel of the plurality of pixels, and a plurality of output buffers configured to output a target data voltage, corresponding to the image data, to data output channels connected to the plurality of pixels, wherein each of the output buffers includes an amplifier output circuit configured to apply a rising current or a falling current, which is previously set for outputting the target data voltage, to an output node connected to one of the data output channels and a slew rate adjustment circuit configured to selectively and further apply an additional rising current or an additional falling current to the output node on the basis of the current control information, for increasing an output slew rate of the target data voltage.
