    摘要: A driving apparatus for over-drive driving includes a display memory, a memory control circuit performing control for receiving input image data supplied from an image rendering device, reading out image data one frame before of the input image data from the display memory and for writing the input image data in the display memory as write image data for the display memory, and a image data control circuit for verifying whether or not the input image data from the memory control circuit coincides with the readout image data one frame before read out from the display memory. The apparatus also includes an LUT for outputting converted image data, a transfer data control circuit for selectively outputting the input image data or the converted image data, and latch circuits for latching image data of one horizontal line equivalent of pixels. A shift register circuit generates latch signal for image data.

    摘要: In a technique of partially serializing video data to transfer it from a display control circuit to a signal-line driving circuit such as a source driver, data comparisons {circle around (1)} and {circle around (2)} in the data order after serialization are made sequentially in a stage of parallel data prior to making a parallel-to-serial conversion of the video data, and determination is made as to whether or not the bit inversion number of the data is more than half to take a control of an inversion/noninversion for the transfer data. An operational speed of a comparator, an inversion/noninversion determination circuit, etc. can be reduced as compared with the case in which a control is taken of the inversion/noninversion for the data of which an operation speed became high by partially serializing the video data.
