  • Publication number: 20100156951
    Abstract: A method for compensating data for a data compensating apparatus in a display apparatus includes converting image data of an n-th frame (where ā€œnā€ is a natural number) into pre-compensation data of the n-th frame having a gray scale less than or equal to a gray scale of the image data of the n-th frame based on pre-compensation data of an (n?1)-th frame, storing the pre-compensation data of the n-th frame, and generating compensation data of the n-th frame having a gray scale greater than or equal to the gray scale of the image data of the n-th frame by using the image data of the n-th frame and the pre-compensation data of the (n?1)-th frame.

  • Publication number: 20100156949
    Abstract: A liquid crystal display includes a timing controller and a liquid crystal panel. The timing controller sequentially receives first through third primitive image signals and sequentially outputs first through third corrected image signals. The liquid crystal panel displays an image based on the first through third corrected image signals. The timing controller generates a first converted image signal having a first gray level based on the first primitive image signal and stores the first converted image signal. The second primitive image signal has a second gray level and the timing controller generates a second converted image signal having a third gray level higher than the second gray level when the second gray level is lower than the first gray level. The timing controller generates the third corrected image signal using the second converted image signal and the third primitive image signal.

  • Publication number: 20100053183
    Abstract: A liquid crystal display includes a liquid crystal panel and a timing controller. The timing controller includes a first memory unit which sequentially receives a first image signal and a second image signal at a first data rate and outputs the first and second image signals at a second data rate, a second memory unit which compresses and stores the first image signal at the second data rate as a compressed first image signal and outputs the compressed first image signal as a restored first image signal, and an image signal compensation unit which receives the second image signal and the restored first image signal at the second data rate, compensates the second image signal to generate a compensated second image signal using the restored first image signal at the second data rate, and outputs the compensated second image signal at the second data rate to the liquid crystal panel.

  • Publication number: 20090309903
    Abstract: 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.

  • Patent number: 7609240
    Abstract: A light generating device includes a brightness detector. The brightness detector extracts a brightness data from an image data. The light generating device compensates the uniformity of a white light whenever the image data that is greater than a reference gray scale is input through the brightness detector. Thus, the light generating device may compensate the uniformity of the white light in real time, so that a display apparatus employing the light generating device may improve a high-quality image.

  • Publication number: 20090109133
    Abstract: A driver for pixels of a display, having pixels arranged into a plurality of pixel blocks including at least two pixels in a row and at least two pixels in a column is presented. The driver includes a first converter, a second converter, and a frame memory. The first converter receives input image signals for a pixel block of the plurality of pixel blocks and generates compressed image signals by compressing the input image signals based on compression reference image signals. The frame memory stores the compressed image signals. The second converter reads the compressed image signals from the frame memory, and restores the compressed image signals based on compression reference image signals to generate restoration image signals. A compression reference image signal for a first pixel of the pixel block is the restoration image signal for a second pixel of a neighboring pixel block.

  • Publication number: 20080122816
    Abstract: A timing controller is adapted to support a display apparatus that operates with image data having a configuration of M-bits per word and an average serial data flow rate corresponding to CK1 image words per second where CK1 is a first clock frequency and M is a whole number. The timing controller includes a data mapper that converts supplied image data from the M-bits per word times CK1 words per second configuration into a P-bits per word times CK2 words per second configuration so that the mapped data matches the configuration of an external memory. The timing controller also includes a data remapper that performs the inverse conversion. In one embodiment, M is 24 while P is 32.
