Abstract:
1. A scan driving circuit with single-type transistors using a liquid crystal display made of single-type thin-film transistors, the scan driving circuit comprising: a first clock input bank comprising a plurality of input signals with different clocks, and connected to a first input end in an nth rank logic circuit; a second clock input bank comprising a plurality of input signals with different clocks, and connected to a second input end in the nth rank logic circuit; wherein said logic circuit includes a plurality of logic circuit units, each of the logic circuit units comprising the first input end, the second input end, a front end and an output end; wherein said first input end and said second input end each respectively comprises a single one of said single-type transistors connected in series to said output end, wherein said front end is a pre-charge node including another single one of said single-type transistors also connected to said output node; and wherein the scan driving circuit is used for receiving control signals for signal outputting with different clocks so as to drive the display units of the liquid crystal display by combining wide pulse waves and narrow pulse waves input through said first and second input ends to obtain a driving signal at said output.
