发明名称 Liquid crystal display apparatus with arbitrary magnification of displayed image
摘要 In a liquid crystal display apparatus including a plurality of gate lines, a plurality of source lines, a plurality of liquid crystal pixels, and a gate line driving circuit, for driving the gate lines, the gate line driving circuit is formed by shift registers for shifting a vertical start pulse signal in response to a clock signal including first pulses and second pulses. Also, a circuit generates said first pulses at an interval of H/a where H is a time period of a horizontal synchronization signal and "a" is a positive integer. Further, a circuit generates the second pulses associated with "c" pulses of "axb" successive ones of the first pulses where "b" and "c" are positive integers and "c" is smaller than "b".
