| 20100265262 | METHOD FOR CORRECTING PIXEL DATA, AND DISPLAY APPARATUS FOR PERFORMING THE METHOD - A method, according to an embodiment, is provided for correcting pixel data provided to a display apparatus. The display apparatus, according to an embodiment, includes a display panel having a plurality of pixels and a light source module having a plurality of light-emitting blocks. The method includes determining a pixel luminance that is a luminance of light provided to each of the pixels; and generating correction data to correct the pixel data, the correction data being generated based on the pixel luminance and a maximum emission luminance that is a maximum luminance of the light emitted from each of the light-emitting blocks. | 10-21-2010 |

| 20100123742 | METHOD OF MODIFYING PIXEL DATA, CONTROL UNIT FOR PERFORMING THE METHOD AND DISPLAY APPARATUS HAVING THE CONTROL UNIT - In a method of compensating pixel data applied to a display panel which receives light from a backlight assembly including a light guide plate and a plurality of light-emitting blocks adjacent a side surface of the light guide plate, block representative values of image blocks are obtained. The block representative values of image blocks respectively correspond to the light-emitting blocks from pixel data of input image. Duty cycles of the light-emitting blocks are determined using the block representative values. Pixel brightness values are calculated using the duty cycles of the light-emitting blocks and brightness profile data in accordance with light-emitting regions of the light guide plate from which the light is emitted when a representative light-emitting block of the light-emitting blocks is driven. The pixel data may then be compensated based on the pixel brightness values. | 05-20-2010 |
| 20100188435 | METHOD FOR DRIVING A LIGHT SOURCE, LIGHT SOURCE APPARATUS FOR PERFORMING THE METHOD AND DISPLAY APPARATUS HAVING THE LIGHT SOURCE APPARATUS - A method of driving a light source includes: determining a location of pixel data of a display relative to a plurality of light-emitting blocks of a light source, obtaining a plurality of luminance values of the light-emitting blocks corresponding to the location by using a lookup table (LUT) storing the luminance values of the light-emitting blocks, generating a plurality of histograms corresponding to the light-emitting blocks, determining a plurality of target luminance values of the light-emitting blocks using the histograms, and driving the light-emitting blocks using the determined target luminance values. The luminance values of the light-emitting blocks are based on the location of the pixel data within an image block of the display corresponding to each light-emitting block. Each of the histograms indicates a frequency of each of the luminance values of a respective one of the light-emitting blocks. | 07-29-2010 |
