The liquid crystal lens includes a first and a second electrode which face each other, a liquid crystal layer interposed between the first electrode and the second electrode and has flat top and bottom surfaces, and a dielectric layer interposed between the second electrode and the liquid crystal layer, where the dielectric layer includes a first and a second dielectric sub-layer, the first dielectric sub-layer made of a material having a different dielectric constant from that of the second dielectric sub-layer, the first dielectric sub-layer includes one or more unit patterns, a surface of each of the unit patterns includes a plurality of flat sections, and a height of each of the unit patterns in a first flat section is different from the height thereof in a second flat section. | 01-03-2013 |
20150039061 | DISPLAY APPARATUS PROVIDING LIGHT THERAPY - A display apparatus providing light therapy includes a display panel configured to display an image to a display region based on input image data, and a lens part disposed on the display panel, the lens part configured to focus the image displayed by the display panel toward a first region in a therapy mode, in which the first region is smaller than the display region, and the first region may correspond to a position of a user's face. | 02-05-2015 |
20150051672 | PHOTO-THERAPY METHOD USING A DISPLAY DEVICE - A photo-therapy method using a display device is provided. The photo-therapy method includes receiving a viewing time input and a photo-therapy selection input, wherein the viewing time input represents an expected viewing time of a user and the photo-therapy selection input represents a photo-therapy selected by the user. The photo-therapy method further includes calculating a period of a photo-therapy image based on the expected viewing time and a suggested treatment time of the selected photo-therapy, and displaying the photo-therapy image with the calculated period while displaying a normal image. | 02-19-2015 |
20150145895 | DISPLAY APPARATUS AND METHOD OF DISPLAYING AN IMAGE USING THE SAME - A display apparatus includes a display panel, an illumination part, an illumination controller, a luminance compensation part and a data driver. The display panel includes data lines, and is configured to display an image in a first direction. The illumination part is configured to emit illumination light having a first color in a second direction opposite to the first direction. The illumination controller is configured to control the illumination part and output an illumination signal corresponding to an intensity of the illumination light. The luminance compensation part is configured to compensate luminance of an input image data based on the illumination signal to output a data signal, and the data driver is configured to generate a data voltage based on the data signal, and output the data voltage to the data lines. | 05-28-2015 |
20150294485 | METHOD OF COMPENSATING AN IMAGE BASED ON LIGHT ADAPTATION, DISPLAY DEVICE EMPLOYING THE SAME, AND ELECTRONIC DEVICE - A method of compensating an image based on light adaptation, a display device employing the same and an electronic device are disclosed. In one aspect, the method includes determining a degree of light adaptation based on an amount of long-wavelength light in an illumination environment where the image is displayed, converting image data in International Commission on Illumination (CIE) red-green-blue (RGB) color space to image data in CIE long-medium-short (LMS) color space for implementing the image via CIE-XYZ color space, applying the degree of light adaptation to the converted image data in the CIE-LMS color space so as to generate compensated image data, and converting the compensated image data in the CIE-LMS color space to image data to be displayed in the CIE-RGB color space via the CIE-XYZ color space. | 10-15-2015 |
20150310826 | DISPLAY DEVICE AND PHOTOTHERAPY METHOD USING THE SAME - Provided is a display device having a phototherapy function. The display device includes a substrate, and a display unit formed on the substrate and including a red pixel, a green pixel, and a blue pixel. The red pixel emits red light having a peak wavelength of 628 nm to 638 nm. A full width at half maximum of red light may be 1 nm or more and 40 nm or less. | 10-29-2015 |
20150324981 | ELECTRONIC DEVICE PROVIDNG A BIOEFFECT IMAGE - An electronic device includes a processor configured to control an operation of the electronic device, a memory device coupled to the processor, where the memory device is configured to operate as a main memory of the electronic device, and a display device coupled to the processor, where the display device is configured to display an original image based on first image data for the original image at a first frame, and to display a bioeffect image based on second image data for the bioeffect image at a second frame. | 11-12-2015 |
20150340012 | IMAGE PROCESSING METHOD AND IMAGE PROCESSING DEVICE FOR PERFORMING THE SAME - An image processing method and image processing device for performing the same are disclosed. In one aspect, the image processing method includes transmitting a content image having a visual condition to a display unit. The method also includes periodically changing the visual condition from a first visual condition to a second visual condition according to a modulation timing such that the content image to be displayed after the modulation timing has the second visual condition different from the first visual condition before commencement of the modulation timing. | 11-26-2015 |
