20090128479 | Display Device and Method of Controlling the Same - A display device includes a driving signal generator being supplied with a synchronous signal and a clock signal and generating an inverter driving signal having a given frequency that is multiplied by a predetermined ratio from a frequency of the synchronous signal, an inverter outputting a driving signal based on the inverter driving signal, and a backlight unit controlling turned-on or turned-off based on the driving signal from the inverter. The driving signal generator operates the number of clocks of the clock signal included in a predetermined period of the synchronous signal by using a predetermined value, defines a magnitude of each section of the inverter driving signal with respect to the predetermined period of the synchronous signal, and adjusts the section magnitude of the inverter driving signal when the number of clocks differs from the total section magnitude of the inverter driving signal based on the magnitude of each section. | 05-21-2009 |
20090309903 | SIGNAL PROCESSING DEVICE FOR LIQUID CRYSTAL DISPLAY PANEL AND LIQUID CRYSTAL DISPLAY HAVING THE SAME - A liquid crystal display system including a signal processing device uses interpolation to generate an intermediate image frame using previous image frame data and present image frame data. The system converts data of the intermediate image frame into transposed image data that is to be used to drive a liquid crystal display panel and display a corresponding image. The transposed image data and the present image data are subjected to a prespecified DCC process (dynamic capacitance compensation process) to thereby generate respective first and second compensation image data. Since the first compensation image data is generated based on the transposed image data and the transposition is configured to prevent over-compensation by the DCC process, over-compensation by the dynamic capacitance compensation process can be reduced or prevented. | 12-17-2009 |
20100053182 | METHOD OF COMPENSATING IMAGE DATA, APPARATUS FOR COMPENSATING IMAGE DATA, AND DISPLAY DEVICE HAVING THE SAME - In a method of compensating image data, a lookup table (LUT) memory storing compensating data that corresponds to received image data is disabled when the received image data is substantially the same as previous image data that is stored in a cache memory. Compensating data that corresponds to the previous image data stored in the cache memory is outputted as compensating data that corresponds to the received image data. The previous image data stored in the cache memory and the compensating data are maintained. | 03-04-2010 |

20100156866 | DISPLAY APPARATUS AND CONTROL METHOD THEREOF - The present invention relates to a display apparatus to synchronize a synchronous signal and an inverter driving signal in response to a display mode, and a control method thereof. A back light unit of the display apparatus makes a back light to dim based on an inverter driving signal, and a dimming frequency of the back light varies in response to a synchronous signal frequency of the image. When a synchronous signal having an abnormal frequency is inputted to the back light unit for several seconds, the back light unit holds the frequency of the inverter driving signal and the frequency of the inverter driving signal varies smoothly in response to the display mode. | 06-24-2010 |
20110316900 | DISPLAY APPARATUS, AND METHOD AND APPARATUS FOR DRIVING THE SAME - A display apparatus includes a display panel, a gate driver, a gray scale compensator, and a date driver. The gate driver sequentially applies gate data to the gate lines. The gray scale compensator compares the primitive gray scale data of the n-th frame with the primitive gray scale data of the (n−1)-th frame to output a compensated gray scale data of a n-th frame, when a primitive gray scale data of a (n−1)-th frame is lower than a gray scale data of a first gray scale and a primitive gray scale data of the n-th frame is higher than a gray scale data of a second gray scale. The date driver converts the compensated gray scale data into a date voltage corresponding to the compensated gray scale data and applies the data voltage to the date line. Therefore, response time of the liquid crystal molecules may be reduced. | 12-29-2011 |
