摘要:
A display apparatus includes a plurality of color filters corresponding to subpixels forming pixels of the display apparatus, and a black matrix formed among the plurality of color filters, and the plurality of color filters includes a pattern indicating an absolute location of each pixel of the display apparatus. A pattern indicating a location of a pixel may be formed in subpixels of a display apparatus and inputting may be performed and thus, a display panel may not affect a thickness as opposed to a digital paper, luminance and a contrast ratio of a display screen may be secured, and location information of the pixel may be intensively represented. Accordingly, the display apparatus may be applicable to a display apparatus having a huge size and a high resolution.

摘要:
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.
摘要:
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.

A bi-directional WDM communication system of the type having central and local offices, and subscribers is provided. The central office includes downstream Bragg reflector lasers for generating downstream channels of different wavelengths, each channel being wavelength-locked to a corresponding incoherent light beam. The central office multiplexes the downstream channels into a downstream optical signal, demultiplexes an upstream optical signal into upstream channels of different wavelengths, and detects the upstream channels. The local office demultiplexes a downstream optical signal into downstream channels, multiplexes upstream channels of different wavelengths into an upstream optical signal, outputs it to the central office, and demultiplexes a broadband light beam into incoherent light beams of different wavelengths. Each subscriber receives the corresponding downstream channel and incoherent light beam, includes an upstream Bragg reflector laser for generating an upstream channel wavelength-locked to the received incoherent light beam, and outputs the upstream channel to the local office.
