Abstract:
A liquid crystal display apparatus capable of generating an image, said image having a magnification M where M is a real number havingan integer portion ""a"" defined by said magnitude M and equal to the numerical value of said magnitude M truncated to the nearest integer, anda decimal portion defined by said magnitude M and equal to M-a, said decimal portion defining quantities ""b"" and ""c"" such that ""b"" and ""c"" are positive integers, c/b is approximately equal to said decimal portion if M.noteq.0, and ""c""=0 and ""b""=1 if M-a=0,said liquid crystal display apparatus comprising:a plurality of gate lines;a plurality of source lines;a plurality of liquid crystal pixels each connected to one of said gate lines and one of said source lines;a gate line driving circuit, connected to said gate lines, for driving said gate lines, said gate line driving circuit being formed by shift registers for shifting a vertical start pulse signal in response to a clock signal including first pulses and second pulses;means for generating said first pulses at an interval of H/a where H is a time period of a horizontal synchronization signal; andmeans for generating said second pulses associated with ""c"" pulses of ""a.multidot.b"" successive ones of said first pulses.
