摘要： Defect mitigation in display panels. Defects in a display panel are mapped, and the defect information is associated with the display system or associated with the panel. During panel operation, the values of pixels neighboring defective pixels are altered to minimize their visibility to the observer. In a first model, luminance error caused by a defect is compensated by adjust neighboring pixels. In a second model, Error in luminance and one of the two chrominance channels is compensated by adjusting neighboring pixels. The defect mitigation methods seek to shift the errors introduced by defective pixels into high spatial frequency elements and chromatic elements, which the human eye is not sensitive to.
