Abstract: A display device includes a light sensor, a controller, a data driver, and a scan driver. The controller is configured to correct an input image signal based on an electrical signal output by the light sensor and an input image signal, the controller includes: a first color coordinate calculation unit configured to calculate a color coordinate of reflected light; a second color coordinate calculation unit configured to calculate a color coordinate of dark room output light for at least two grayscale value sections; a combination unit configured to combine the reflected light color coordinate and the dark room output light color coordinate together; and a gamma value setting unit configured to set a gamma value based on a deviation between the combination light color coordinate output by the combination unit and a reference color coordinate.

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 head mounted display device includes a display panel including a first display region and a second display region which is arranged at a first angle with respect to the first display region; a reflective panel arranged at a second angle with respect to the second display region, to output a first transmitted light by transmitting a first light which is output from the first display region, and to output a second reflected light by reflecting a second light output from the second display region; and a lens to collect the first transmitted light and the second reflected light.
