20120081410 | METHOD OF DRIVING DISPLAY PANEL AND DISPLAY APPARATUS FOR PERFORMING THE SAME - Rather than using complex zigzag patterns or the like for counter-compensating for the different lengths of fanout lines used to transmit data line drive voltages from more concentrated source points of the drive voltages to more spread apart data lines of a given display panel, digital data signals that represent the to be output data line drive voltages are automatically adjusted so that the data line drive voltages output from the concentrated source points are pre-adjusted to counter voltage drop difference effects that will be applied to those pre-adjusted data line drive voltages by the difference of resistances among the fanout lines of different lengths. | 04-05-2012 |
20120139882 | METHOD FOR RESTORING A TIMING CONTROLLER AND DRIVING DEVICE FOR PERFORMING THE METHOD - A method of restoring a timing controller includes generating an error condition signal from a timing controller by checking abnormality of an image signal and a control signal provided from an image board, feeding back the error condition signal to the image board, and restoring the timing controller based on the error condition signal. | 06-07-2012 |
20120162158 | DISPLAY APPARATUS SET - A display apparatus set includes a signal receiver/transmitter, a scaler, a driving circuit, and a first display panel. The signal receiver/transmitter receives an image signal from an external device, outputs a portion of the image signal as a first image signal, and outputs a remaining portion of the image signal as a second image signal. The scaler receives the first image signal and converts a size and a resolution of an image included in the first image signal to output the converted first image signal. The driving circuit receives the converted first image signal and converts the converted first image signal to output a data signal. The first display panel receives the data signal to display an image. The second image signal is similarly treated and displayed on a second display panel. | 06-28-2012 |
20120257825 | METHOD FOR CORRECTING A DEFECT PIXEL - A method for correcting a defect pixel includes extracting a pixel value of a central pixel, and pixel values of each of a plurality of neighboring pixels around the central pixel in an image sensor by using a color filter; calculating reference levels by multiplying each the pixel value of the plurality of neighboring pixels by a weight value; calculating a total number of cases where the pixel value of the central pixel is larger or smaller than the reference level as a first comparison value or second comparison value, respectively; determining the central pixel is a defect pixel where the first or second comparison value is larger than a first or second control register value, by comparing the comparison values with the control register values, respectively; and correcting the central pixel determined as the defect pixel. | 10-11-2012 |

20130201180 | METHOD OF COMPENSATING A STAIN, A METHOD OF DRIVING A DISPLAY PANEL HAVING THE METHOD OF COMPENSATING A STAIN AND A DISPLAY APPARATUS FOR PERFORMING THE METHOD OF DRIVING THE DISPLAY PANEL - A stain compensating method that includes detecting a luminance distribution of a display panel, dividing, using the luminance distribution, luminance profiles of stains overlapped with each other into individual luminance profiles for each of the stains, determining an area and a shape of the stain corresponding to one of the individual luminance profiles, generating a stain compensating value for the stain, and compensating input image data using the stain compensating value. | 08-08-2013 |
20130321253 | LIQUID CRYSTAL DISPLAY - A liquid crystal display includes a display panel, a timing controller, a gate driver, and a data driver. The display panel includes a plurality of pixels. The timing controller receives an image data, compares a previous line data with a present line data to determine whether the present line data needs to be compensated, and generates a first modulation line data. In addition, the timing controller calculates the first modulation data and a delay compensation value to generate a second modulation line data. The delay compensation value is decided from reference delay compensation values of reference pixels among the pixels. | 12-05-2013 |
