Patent ID: 8223111

Claim:
An LCD device providing bi-directional stabilization comprising: a display area in which a plurality of parallel gate lines are disposed; a non-display area having a first area and a second area, wherein the first and second areas are located on opposite sides with respect to the display area; a shift register having a plurality of shift register units coupled in series, wherein a shift register among the plurality of shift register drives a corresponding gate line among the plurality of gate lines and comprises: a first circuit disposed in the first area and comprising: a pulse generator for generating a driving signal based on an input signal, the pulse generator comprising: an input end for receiving the input signal; an output end coupled to a first end of the corresponding gate line for outputting the driving signal; and a node; a first transistor having a first channel width/length ratio for maintaining a voltage level of the node based on a first control signal, the first transistor comprising: a first end coupled to the node; a second end for receiving a first voltage; and a control end for receiving the first control signal; and a second circuit disposed in the second area and comprising: a second transistor having a second channel width/length ratio for maintaining a voltage level at a second end of the corresponding gate line based on a second control signal, the second transistor comprising: a first end coupled to the second end of the corresponding gate line; a second end for receiving a second voltage; and a control end for receiving the second control signal; wherein the first channel width/length ratio is smaller than the second channel width/length ratio and the layout area of the first circuit is larger than the layout area of the second circuit.
