摘要： A display device and a method for driving the same, in which the display device includes a storage unit for storing a plurality of reference gradation code data corresponding to a plurality of gradations, and some of variable gradation code data corresponding to some of the gradation points of the plurality of gradations; a signal controller for converting gradations of original pixel data into gradation code signals of different levels using the plurality of reference gradation code data or both the plurality of reference gradation code data and the some variable gradation code data according to an operation mode; a data driver for converting the gradation code signal into an analog pixel data signal; and an image display unit for displaying an image according to the pixel data signal. The original pixel data are converted into gradation code signals of different levels according to an image display mode, thereby preventing luminance degradation and flicker generation due to the image display mode. Only the reference gradation code data and some of the variable gradation code data are stored in the memory to thereby reduce the amount of data stored in the memory, so that manufacturing costs of display devices caused by additional memories can be reduced.

摘要： 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.

摘要： A signal processing device includes a memory in which a color correction data is stored. The memory stores a first color correction data having the same number of bits as an input image data and a second color correction data having fewer number of bits than the input image data. The number of color correction data corresponding to a low gray-scale range increases and the number of color correction data corresponding to a high gray-scale range decreases by the same amount that the number of the color correction data corresponding to the low gray-scale range increased. Thus, a color characteristic corresponding to the low gray-scale range may be improved without changing the total number of color correction data.
