Abstract: A method of compensating for Mura in a display panel includes displaying a high gray-scale image and a low gray-scale image on a display panel. The displayed images are photographed to generate a high gray-scale luminance image and a low gray-scale luminance image. An ELA Mura for-measurement image having moiré-removed luminance values is generated by dividing luminance values of the low gray-scale luminance image by luminance values of the high gray-scale luminance image. One-dimensional average data is obtained from the ELA Mura for-measurement image. The one-dimensional average data is transformed into frequency-domain data. Target frequency-domain data having a maximum peak value is identified from the frequency-domain data. A direction, an intensity, and a frequency of the ELA Mura are obtained from the target frequency-domain data. A filter is determined based on the obtained information. The filter is applied to image data.

Abstract: A color gamut controlling device and a display device including the color gamut controlling device. The color gamut controlling device includes a light sensing unit, a first calculation unit, a second calculation unit, and a color gamut calculation unit. The light sensing unit measures a luminance of external light. The first calculation unit calculates adjusted tristimulus values for each of three primary colors based on the measured luminance. The second calculation unit calculates final tristimulus values for each of the three primary colors using the adjusted tristimulus values and target tristimulus values for each of the three primary colors. The color gamut calculation unit calculates a corrected color gamut from the final tristimulus values. The light sensing unit may further measure tristimulus values of the external light for each of the three primary colors.

Abstract: An image display method is disclosed. In one aspect, the image display method includes receiving image data including a black region and a white region, determining a boundary between the black and white regions, determining a pixel to be corrected which is adjacent to the boundary, and determining a direction of the boundary and an arrangement of the black and white regions with respect to the boundary. The method also includes converting pixel data corresponding to the pixel into corrected pixel data based at least in part on the boundary direction and the arrangement and displaying images on a display device based at least in part on corrected image data including the corrected pixel data.
