DISPLAY DEVICE, DATA PROCESSING APPARATUS AND METHOD THEREOF

摘要

According to an embodiment of the present invention, a data processing device for a display device which includes a plurality of pixels, wherein each of the pixels includes R (red), G (green), B (blue), and G (green) sub pixels. The data processing device comprises an input gamma processing unit which applies a gamma function to image data with gradation data of each of R, G, and B to process the image data into linearized image data; a low-power sub pixel rendering unit which renders the linearized image data according to the layout of the sub pixels included in the pixels using a 3 x 1 rendering filter and outputs linearized second sub pixel data; and an output gamma processing unit which applies an inverse-gamma function to the linearized second sub pixel data to process the linearized second sub pixel data into non-linearized second sub pixel data.
