Problems solved by technology

In this discussion, display panels are described as "substantially" comprising repeating groups of sub-pixels, since it is understood that size and / or manufacturing factors or limitations of the display panel may result in Subpixel repeating groups are incomplete panels

Abstract

The subpixel rendering component of a display system provides the capability to substitute a second subpixel rendering filter for a first subpixel rendering filter for computing the values of certain subpixels on the display panel when the input image data being rendered indicates an image feature that may give rise to a color balance error at some portion of the displayed output image. An image processing method of correcting for color balance errors detects the location of a subpixel being rendered, and for certain subpixels, detects whether the input image data indicates the presence of a particular image feature. When the image feature is detected for particular subpixels being processed, a second subpixel rendering image filter is substituted for a first subpixel rendering image filter.

Description

technical field [0001] The subject matter of the present invention relates to an image display device, and more particularly to an image processing method for achieving color-balanced white at the edge of a display panel with a two-dimensional (2D) high-brightness sub-pixel layout. Background technique [0002] Commonly owned U.S. Patent No. 7,123,277, entitled "CONVERSION OF A SUB-PIXELFORMAT DATA TO ANOTHER SUB-PIXEL DATA FORMAT," to Elliott et al. The method of inputting image data specified by the primary color in the first format displayed on the panel. Subpixels are arranged in subpixel repeating groups having a primary color of a second format different from the input image data of the first format. It is worth noting that in US7,123,277, sub-pixels are also referred to as "emitters". Everything taught by US 7,123,277 is incorporated herein by reference. [0003] The term "primary color" refers to each color that occurs within a repeating group of subpixels. A dis...
