Abstract:
A method of operating a light emitting, image display device that is configured to normally display to one or more viewers, a corresponding image thereof with a relatively wide viewing angle and relatively good contrast, includes selectively outputting to one or more peripheral portions of the wide viewing angle, privacy-protecting light rays of sufficient luminance to substantially reduce, for corresponding viewers viewing from the respective one or more peripheral portions of the relatively wide viewing angle, the otherwise normal and relatively good contrast of the image so as to thereby inhibit viewing of the image from the respective one or more peripheral portions. In one embodiment, the method is carried out using an organic light emitting diode (OLED) panel and a light source part disposed on a backside of the OLED panel and comprising at least one light guide plate and at least one light source.

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:
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.
