20080218489 | DISPLAY DEVICE AND METHOD OF DRIVING THE SAME - A method of driving a display device having a plurality of pixels, a plurality of sensing units, and a plurality of sense data lines to which the plurality of sensing units are connected, includes: reading sense signals from the sense data lines; determining whether or not the display has been touched and the number of touches, generating X-axis and Y-axis position data based on the sense signals, and determining, when the quantity of touches is plural, whether a plurality of touches are sequentially generated, and the touch position of each. | 09-11-2008 |
20090152441 | LIGHT SENSOR TEST UNIT, METHOD OF TESTING LIGHT SENSOR USING THE SAME AND DISPLAY APPARATUS - In a light sensor test unit, a test circuit is built in a display panel and connected to an output node of a light sensor which senses an intensity of an external light. When external light having a predetermined intensity is provided to the light sensor, the test circuit outputs a driving signal in response to a sensing signal output from the output node. A test pixel part includes pixels selected from a plurality of pixels arranged in the display panel and receives the driving signal from the test circuit to display a gray-scale corresponding to the driving signal. A brightness measurer measures a brightness corresponding to the gray-scale displayed in the test pixel part to compare the measured brightness with a predetermined brightness, thereby testing whether the light sensor built in the display panel is normally operated. | 06-18-2009 |
20090244418 | Liquid Crystal Display and Method for Manufacturing the Same - A liquid crystal display includes a substrate, a plurality of gate lines formed on the substrate, a plurality of data lines intersecting the gate lines, a plurality of common voltage lines formed in the same layer as the data line and parallel to the data lines and transmitting a common voltage, a plurality of thin film transistors connected to the gate lines and the data lines, and a plurality of pixel electrodes respectively connected to the thin film transistors, arranged in a matrix shape, each of the plurality of pixels including a first edge parallel to the gate lines and a second edge having a shorter length than the first edge and neighboring the first edge. | 10-01-2009 |
20090262058 | DISPLAY APPARATUS HAVING REDUCED KICKBACK VOLTAGE - A display apparatus includes; a display panel including a plurality of data lines which receive a data signal, a plurality of gate lines which receive a gate signal and a plurality of pixels, a data driving circuit which provides the data liens with the data signal, and a gate driving circuit which sequentially applies the gate signal to the plurality of gate lines, wherein an area between an i | 10-22-2009 |
20100007597 | LIQUID CRYSTAL DISPLAY AND METHOD OF DRIVING THE SAME - A liquid crystal display (“LCD”) includes: a liquid crystal panel, a timing controller which receives previous image data and current image data, corrects or does not correct the current image data according to a reference bit of conversion image data generated using the previous image data, and outputs a display image signal to the liquid crystal panel, and a data driver which receives the display image signal and applies a data voltage corresponding to the display image signal to the liquid crystal panel. | 01-14-2010 |
20100149200 | DISPLAY, APPARATUS AND METHOD FOR DRIVING DISPLAY - An apparatus for driving a display panel includes a first memory which stores a frame image data, a second memory which stores overshooting information. The apparatus receives an image signal from an external system via a CPU interface process. The second memory stores a difference data between the frame image data and an overshooting data. The overshoot is then calculated from the difference data and the frame image data. The apparatus also includes a two-line memory which stores an image signal of an n-th frame in a line unit and an image signal of an n−1-th frame in another line. The two-line memory compares the consecutive two frame data, so that the apparatus extracts overshooting information from a look up table. | 06-17-2010 |
