Abstract
One aspect of the present disclosure relates to a common repair structure for repairing scanning and/or data line defects in a liquid crystal display panel. In one embodiment, the common repair structure includes a plurality of “H” shaped structures, where each “H” shaped structure is placed over a corresponding segment of two neighboring scanning lines located between and associated with two neighboring pixels along the second direction or a corresponding segment of two neighboring data lines located between and associated with two neighboring pixels along the first direction.

A common repair structure for repairing scanning line and/or data line defects in a liquid crystal display (LCD) panel, wherein the LCD panel comprises a plurality of scanning lines arranged in a first direction, a plurality of data lines arranged crossing over the plurality of scanning lines in a second direction substantially interlaced to the first direction, thereby defining a plurality of crossovers therebetween, and a plurality of pixels associated with the plurality of scanning lines and data lines, comprising:
- (a) a plurality of first “H” shaped structures, each first “H” shaped structure being not connected to the other first “H” shaped structures, wherein each first “H” shaped structure has a first strip, a second strip, and a third strip connected to and between the first and second strips, each of the first and second strips having a first end portion and an opposite, second end portion, and is placed over a corresponding segment of two scanning lines located between and associated with two pixels along the second direction such that the first end portions of the first and second strips overlap with one of the two scanning lines, while the second end portions of the first and second strips overlap with the other of the two scanning lines, wherein each first “H” shaped structure is connectable selectively to one of the two scanning lines in the corresponding segment;
- and
- (b) a plurality of second “H” shaped structures, each second “H” shaped structure being not connected to the other second “H” shaped structures, wherein each second “H” shaped structure has a first strip, a second strip, and a third strip connected to and between the first and second strips, each of the first and second strips having a first end portion and an opposite, second end portion, and is placed over an individual segment of two data lines located between and associated with two pixels along the first direction such that the first end portions of the first and second strips overlap with one of the two data lines, while the second end portions of the first and second strips overlap with the other of the two data lines, wherein each second “H” shaped structure is connectable selectively to one of the two data lines in the corresponding segment.
