A method of driving a display panel including a plurality of pixels including a red (R), green (G), blue (B), and white (W) sub-pixels is provided. The method includes receiving image data, converting RGB data included in the image data into RGBW data, and driving the display panel based on the converted RGBW data. The converting includes converting the RGB data into YCbCr data and determining a W value of the RGBW data based on a Y value of the converted YCbCr data.

Display apparatus and display panel driving method thereof

A method and apparatus for removing an image blocking artifact by using a transformation coefficient are provided. The method includes: detecting a first blocking artifact which is in a flat region of the input image; removing the first blocking artifact using a number of low frequency coefficients from among transformation coefficients for each transformation block of a plurality of transformation blocks of the input image, based on a result of detecting the first blocking artifact; detecting an edge region of the input image; and removing a second blocking artifact, which is in an edge region of an intermediate image obtained from the removing of the first blocking artifact of the input image, based on the detected edge region in the input image.
