ABSTRACT:
An LCD controlling apparatus wherein a horizontal filter and a vertical filter, which are digital filters, are independently constructed, which can improve a resolution by horizontally and vertically processing input image data to enhance the edge portion thereof, includes a main block for synthesizing or generating clocks necessary for internal operation and wholly controlling the internal operation, an image edge processing block for receiving image data from the main block and horizontally processing pixels of to-be-processed-image data and their horizontally adjacent pixels, receiving the horizontally processed image data and vertically processing pixels of to-be-processed image data and their vertically adjacent pixels, and an LCD interface block for rearranging pixels of image data horizontally and vertically processed in the image edge processing block to be suitable for pixel structure, linearly processing light transmission characteristics of the rearranged pixels and performing compensation according to temperature to then be divided into multiple block image data according to driving clocks of the respective pixels for output.
