US 2014/0232735 A1 · DISPLAY DEVICE, DATA PROCESSOR AND METHOD THEREOF

Abstract

A data processor for a display device that includes a plurality of pixels, each of which includes red, first green, blue, and second green sub-pixels, may include an input gamma processor for processing image data including red, green, and blue grayscale data into linearized image data by applying a gamma function to the image data, a first sub-pixel rendering unit for rendering the linearized image data according to layout of a plurality of sub-pixels included in the plurality of pixels using a 3×1 rendering filter to output linearized second sub-pixel data, and an output gamma processor for processing the linearized second sub-pixel data into non-linearized second sub-pixel data by applying an inverse gamma function to the linearized second sub-pixel data.
