Abstract
Video display apparatus having a flat X-Y matrix display panel comprised of an X-Y array of display elements for displaying a picture derived from a video signal. An analog-to-digital converter obtains m samples of a line of the video signal, each sample being formed of n bits of different bit levels from the least significant bit level to the most significant bit level. A memory stores each sample in a respective one of m storage locations, each storage location including n storage compartments for storing the n bits of a sample, respectively. All of the bits of one level are serially read out from the corresponding storage compartment in all of the n storage locations, and then all of the bits of the next level are read out from the corresponding storage compartment in all of the m storage locations, and so on, in succession, until the bits of all levels have been read out from the m storage locations. For example, all of the least significant bits of the m storage locations are read out serially, then the next more significant bits in all of the m storage locations are read out, and so on, until all of the most significant bits are read out of the m storage locations.
