PURPOSE: A method and system for inserting a black line of an excessively large liquid crystal imager are provided to reduce the need of a memory and a bandwidth, thereby simplifying circuits and cutting down manufacturing costs. CONSTITUTION: A method of black line insertion for excessively large imagers having random row access is composed of steps of periodically writing in a predetermined number of input video lines into a memory(502), speeding up the reading of the predetermined number of input video lines out from the memory to supply a time enhancement(504), multiplexing a black input line with the sped-up predetermined number of input video lines during the time enhancement to supply an output image(506), and presenting the output image on the excessively large imager by using the random row access to place the lines in the correct vertical position(508).
