  • Patent number: 8982287
    Abstract: Provided is a data processing apparatus including a correction circuit. In at least one embodiment, the data correction circuit acquires pixel data of a first pixel for display of a first color component and pixel data of a second pixel for display of a second color component, the second pixel being driven by a scanning signal line which drives the first pixel and being driven by a data signal line which is adjacent to the first pixel, and corrects the pixel data of the second pixel in accordance with a relationship between a value of the pixel data of the first pixel and a value of the pixel data of the second pixel. Thus, it is possible to cause a liquid crystal driving panel to perform uniform display without causing display unevenness even in a case where a halftone of a specific color component is uniformly displayed.

  • Patent number: 8817111
    Abstract: This invention provides a calibration system and method for multi-unit display systems without a need for switching the system input resolution/configuration of the display system while calibrating. This serves to avoid carrying out a re-synchronization step. As such, this system and method allows for increases speed and reduced likelihood of failure. This system and method also corrects the display system by providing an arrangement that employs a minimum of required changes so as to avoid any changes that can consequently affect the output image of the display system. Calibration of the system of display units occurs free of any changes to the input resolution and this resolution is maintained in a manner that resists change unless specifically required. Moreover, this system and method enables a resolution for the overall system that differs from the sum of the input resolutions of the discrete, individual display units in the collection.

  • Publication number: 20030038898
    Abstract: The automatic cut-off system includes a video data processing circuit, a cut-off control circuit, a drive circuit, and a level control section. The video data processing circuit adds a cut-off reference pulse having a predetermined level to primary-color signals of red (R), green (G) and blue (B) at different timings within a single vertical blanking interval, and outputs latch timing signals respectively indicating the timings. The cut-off control circuit shifts a level of each primary-color signal having the cut-off reference pulse added thereto based on a corresponding cut-off control signal. The drive circuit drives each cathode of a CRT (cathode-ray tube) based on a corresponding one of the shifted primary-color signals, and outputs a voltage corresponding to each cathode current as a common feedback signal. The level control section latches the feedback signal in response to each latch timing signal, and outputs the cut-off control signal of one of the primary-color signals.

  • Publication number: 20020093586
    Abstract: A CRT device with an electron gun provided therein includes control means for controlling voltages applied to a cathode and a control electrode constituting the electron gun. The control means exerts control on each electrode voltage so that the difference between the cutoff voltage of the cathode and the voltage of the control electrode is greater when the luminance level of a luminance signal separated from picture signal is higher, thereby minimizing a spot diameter.

  • Patent number: 5682180
    Abstract: An electronic display generates an image which, through substantial registry of two opponent vector images, is perceived as a full color image. The display receives two channels of information representing two opponent color vectors of an image to be displayed, develops two images in the two opponent color vectors, and superimposes the two images to generate the image which is perceived as a full color image.

  • Patent number: 5612710
    Abstract: A large scale video display of the present invention is designed to receive a standard NTSC video signal and display it on a large scale array of low cost, voltage or current controlled lamp transducers. The video signals are received by a video capture device which receives and digitizes the video signal. A host processor formats the digital data into a number of 16 bit data words each corresponding to a pixel. A coprocessor receives the 16 bit data words and reformats the data. The reformatted data is connected to a large scale display by a fiber optic connection. The display includes a number of transceivers which receive the formatted video data in a memory buffer. The transceivers also receive a board map from the coprocessor. The map indicates which light boards correspond to each part of the memory where the frame image is stored. This information is used by a number of controllers to determine which lights to turn on and at what level of brightness for any given time.
