Abstract:
A display device and method having a pattern are provided. The display device includes a plurality of color filters which correspond to one or more sub-pixels constituting a pixel of the display device; and a black matrix formed between the plurality of color filters, wherein the one or more sub-pixels include one or more position marks indicating an absolute position of each pixel of the display device and one or more error correction marks for correcting an error when the one or more position marks are detected.
Abstract:
An apparatus and methods for recognizing an image with an increased image recognition rate are provided. The apparatus includes a plurality of illuminators for illuminating a surface. The apparatus also includes an image sensor for outputting an image frame obtained by converting an optical image of the surface into an electrical signal. The surface is illuminated one of the plurality of illuminators. The apparatus further includes a switch for selecting any of the plurality of illuminators for illuminating the surface. The apparatus additionally includes a controller for receiving the image frame from the image sensor, determining whether the image frame has a region of reflected light, and controlling the switch to select another of the plurality of illuminators to illuminate the surface when the image frame has the region of reflected light.
Abstract:
A display device including a pattern includes a plurality of color filters corresponding to one or more subpixels forming pixels of the display device, and a black matrix formed between the plurality of color filters, wherein the one or more subpixels include one or more marks representing absolute positions of the respective pixels of the display device, and each of the subpixels includes symmetric marks at a left side and a right side of the subpixel. Accordingly, the quantity of light emitted from each of Red, Green, and Blue subpixels is uniform, and the generated pattern has marks that are positioned where the pattern noise is minimized, is provided, thereby providing an improved image quality display device.
Abstract:
A display device including a plurality of display panels and one or more vibration sensors for detecting a vibration by a touch of an input device. The vibration sensors are attached to the plurality of display panels The display device also includes a controller for, when one of the plurality of display panels is touched by the input device, identifying the display panel touched by the input device from the plurality of display panels according to vibration intensities detected by one or more vibration sensors. A display panel on which an input by an electronic pen is performed among multiple display panels can be identified through vibration intensities, so that input position detection using pattern recognition can be achieved even when the plurality of display panels are used.
