20090256865METHOD FOR GENERATING DATA FOR DRIVING A DISPLAY PANEL, DATA DRIVING CIRCUIT FOR PERFORMING THE SAME AND DISPLAY DEVICE HAVING THE DATA DRIVING CIRCUIT - A method for generating data for driving a display panel is provided in which first compensation data of (N+k) bits, corresponding to grayscale data of N bits, is generated, wherein values of N and k are natural numbers. A first gamma curve is applied to the first compensation data of (N+k) bits. Second compensation data of (N+k) bits, corresponding to the grayscale data of N bits, is generated. A second gamma curve is applied to the second compensation data of (N+k) bits. The first compensation data or the second compensation data are selectively output and converted into analog data signals. The analog data signals are output to a data line. Accordingly, the first compensation data and second compensation data includes a multidomain structure which improves display quality. A data driving circuit and a display device including the data driving circuit for performing the method are also provided.10-15-2009
20090267890METHOD OF LOCAL DIMMING A LIGHT SOURCE, LIGHT SOURCE APPARATUS FOR PERFORMING THE METHOD, AND DISPLAY APPARATUS HAVING THE LIGHT SOURCE APPARATUS - In a method of local dimming a light source, which includes driving a light source including a plurality of light-emitting blocks by individually driving the light-emitting blocks, the dimming level of each light-emitting block is determined. In the method, the luminance of a first light-emitting area may be adjusted according to a size of the first light-emitting area corresponding to a display area in which an image having a maximum luminance is displayed.10-29-2009
20100128028METHOD OF DRIVING A DISPLAY PANEL, AND DISPLAY APPARATUS FOR PERFORMING THE METHOD - Disclosed is a method of driving a display panel, which includes a plurality of data lines, a plurality of gate lines, a first pixel column electrically connected to an N-th gate line and a second pixel column electrically connected to an (N+1)-th gate line adjacent to the N-th gate line (wherein N is a natural number). In the method, compensation data of the first pixel for compensating for a kickback deviation between the first and second pixel columns is generated using first data and second data corresponding to the first and second pixel columns, respectively. The compensation data of the first pixel column and the second data of the second pixel column are converted to data voltages of an analog type to output the data voltages to the data lines.05-27-2010
20100207928Gate Driving Circuit and Display Device Having the Gate Driving Circuit - A gate driving circuit includes a plurality of stages connected to each other. An m-th stage (‘m’ is a natural number) of the stages includes a pull-up part, a pull-down part, a first holding part and a second holding part. The pull-up part outputs a high voltage of a clock signal as a high voltage of an m-th gate signal in response to a high voltage applied to a first output control part. The pull-down part pulls down the high voltage of the m-th gate signal to a first low voltage in response to a high voltage of an (m+1)-th gate signal. The first holding part holds a voltage applied to the first output control part as a second low voltage having a level lower than the first low voltage. The second holding part holds a low voltage of the m-th gate signal to the first low voltage.08-19-2010
20110012887DISPLAY APPARATUS - A display apparatus includes a display panel and a data driving part. The display panel includes pixels, data lines and gate lines. A transverse side of the pixels is disposed adjacent to the data lines extending along a first direction, and a longitudinal side of the pixels is disposed adjacent to the gate lines extending along a second direction. Two adjacent pixels of the pixels disposed adjacent to each other along the second direction are connected to one gate line of the gate lines. The data driving part transmits two-dot-inversed first direction data voltages to pixels disposed along the second direction and two-dot-inversed second direction data voltages to pixels disposed along the first direction.01-20-2011

20090267926METHOD FOR DRIVING LIGHT SOURCE BLOCKS, DRIVING UNIT FOR PERFORMING THE METHOD AND DISPLAY APPARATUS HAVING THE DRIVING UNIT - A display apparatus includes light source blocks driven as follows in displaying at least one frame (possibly every frame). An image to be displayed includes image pixels. Each light source block corresponds to an image pixels block which is a block of image pixels to be displayed directly opposite to the light source block. For each image pixels block, a block mean value and a block maximum value are determined. A parameter is determined which corresponds to a total luminance of the frame. For each image pixels block, a block representative value is determined which corresponds to the parameter, the block representative value being within a range between the block mean value and the block maximum value inclusive. During the frame, each light source block is driven to provide a luminance which is an increasing function of the corresponding block representative value.10-29-2009
