A display device constituting a multi-display system is provided, which includes an input connector configured to receive an input image; a main processor configured to process an image corresponding to a display device from an input image; a display configured to display a processed image; an output connector configured to transmit an input image to an adjacent display device connected to a display device; and a sub-processor configured to transmit, when a display device wakes up, a booting command to a main processor, transmit a wakeup signal to an adjacent display device, extract information that is necessary for image processing from an input image, and then transmit an input image to a main processor.

Display device constituting multi-display system and control method thereof

A display system is disclosed. The display system includes a plurality of display apparatuses which are rotated in a vertical direction and disposed parallel to each other, wherein the plurality of display apparatuses may reverse and change the width and height of one received image, and may display each of the divided sub images by as many as the number of the plurality of display apparatuses, according to a location of disposition. Accordingly, the plurality of display apparatuses may display an image in the same ratio of a screen ratio of a received image without ratio readjustment or data distortion.

Display system and control method thereof

A method of adjusting a displaying state of a display apparatus includes determining a reference color temperature and a reference &#x394;u'v&#x2032;, determining setting color temperatures corresponding to gradations of a gray level according to the reference color temperature to make color temperature differences between adjacent gradations of the gray level be within a predetermined color temperature range, measuring coordinates according to the gradations within a gray area formed by the gray level and displayable in the display apparatus on a predetermined color coordinates system corresponding to the reference &#x394;u&#x2032;v&#x2032; and the setting color temperatures corresponding to the gradations, and setting the coordinates corresponding to the gradations measured about each gradation of the gray level of the display apparatus. Thus the method of adjusting a displaying state of a display apparatus varies a color sensation to have directionality and linearity between gradations of a gray level, thereby improving color representation.

Method of adjusting displaying state of display apparatus

A reflective photomask and a method of determining or optimizing thicknesses of layers of the reflective photomask are provided. The reflective photomask may include a substrate, a reflective layer, an absorptive pattern, and a spacer. The substrate may include a reflective region and an absorptive region, the reflective layer may be formed between the reflective and absorptive regions, the absorptive pattern may be formed on the reflective layer corresponding to the reflective region, and the spacer may be formed at an upper portion, lower portion, or inside of the reflective layer so as to correspond to the reflective region.
