Abstract: VIDEO DISPLAY APPARATUS HAVING A FLAT X-Y MATRIX DISPLAY PANEL               ABSTRACT OF THE DISCLOSURE          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 corre-sponding 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 loca-tions.  An enabling circuit enables successive lines of the dis-play elements in the display panel to be energized on a line-by-line sequential basis.  An energizing circuit is supplied in parallel with the m bits of each bit level, sequentially by level, as the m bits are read out from the storage locations, to energize selected ones of the displayed elements in an enabled line in accordance with the bit values of the read out bits.  In the preferred embodiment, each bit level of read an bits is stored -i-temporarily.  As the significance of the bit level increases, the storage time for such bits likewise increases.  Hence, the least significant bits are temporarily stored for the shortest time period and the most significant bits are stored for the longest time period.                             -ii-
