Abstract: PURPOSE: A signal process device and a liquid crystal display device including the same are provided to remove a display failure of a liquid crystal display panel by preventing an excessive compensation voltage corresponding to compensation data from being applied to the liquid display panel. CONSTITUTION: A memory(110) receives image data of a current frame and outputs the image data of a previous frame which is previously stored. A lookup table outputs the reference gray value display from the liquid display panel for the previous frame by the combination of the current data and the previous data as the previous compensation data. A first data compensation unit(150) receives the current data and converts the current data to the first sub data and the second sub data with different gray values. The first data compensation unit receives the previous compensation data from the lookup table and converts the data into the third and fourth sub data with the different gray value. A second data compensation unit(170) converts the first sub data to the first compensation data using the first and third sub data. The second data compensation unit converts the second sub data to the second compensation data using the second and fourth data and outputs the second compensation data.

Abstract: PURPOSE: A signal process device for a liquid display panel and a liquid crystal display device including the same are provided to improve a response speed by applying a compensation voltage to a current frame. CONSTITUTION: A motion interpolation unit(120) produces a motion vector and generates a middle image data based on the motion vector. A lookup table substitutes a first reference gray value which a liquid crystal display panel displays by the middle image data for the target gray value of the middle image data. The lookup table outputs the substituted first reference gray value as the first substitution image data. A memory(110) receives and stores the first substitution image data and the current image data. The memory successively outputs the current image data and the first substitution image data for the current frame. A data compensation unit(140) generates the first compensation image data and the second compensation image data and compensates for the response characteristic of the liquid crystal panel based on the first and second compensation image data.

Abstract: A method and an apparatus for driving a liquid crystal display device are provided to generate DCC data on the previous and current frames by generating the DCC data using interpolation, when no inflection point is present on a brightness response waveform. A timing controller(106) converts an input data signal to DCC(Dynamic Capacitance Compensation) data using a data compensator and provides the DCC data to a data driver. The data compensator(130) includes a frame memory and an LUT(Look-Up Table). A gate driver(102) uses a gate control signal from the timing controller to generate a scan signal, which sequentially drives gate lines of an LCD(Liquid Crystal Display) panel according to horizontal periods. The data driver(104) converts digital data to analog data signals in response to a data control signal from the timing controller and supplies the converted signal to the data lines, at every horizontal periods gate lines of the LCD panel are activated. Plural sub-pixels are arranged on the LCD panel(108). The sub-pixels are driven in response to a scan signal from the gate driver and store the data signal from the data driver.
