Display panel and repair method thereof

摘要

A flat display panel and a related repairing method are provided. The flat display panel includes multiple horizontal repair lines parallel to scan lines and multiple vertical repair lines parallel to data lines. The vertical repair lines are disposed on one side of the data lines one to one, and the horizontal repair lines are disposed on one side of the scan lines one to one. When one of the data lines or one of the scan lines is broken, an electrical route formed by a use of the vertical repair lines or the horizontal repair lines detours the broken scan line or data line, so as to deliver signal to pixel electrode normally.

主权项

1. A flat display panel, comprising:
a plurality of matrix-arranged pixel electrodes; a plurality of scan lines, parallel to one another and extended along a first direction, for transmitting a scan signal; a plurality of data lines, parallel to one another and extended along a second direction, the second direction being perpendicular to the first direction, for transmitting a data signal; a plurality of switching transistors, coupled to the plurality of pixel electrodes, to the plurality of scan lines, and to the plurality of data lines one to one, each of the plurality of switching transistors used for receiving the scan signal transmitted through each of the plurality of scan lines coupled to each of the plurality of switching transistors and for conducting the data signal transmitted through each of the plurality of data lines coupled to each of the plurality of switching transistors to the corresponding pixel electrode; a plurality of horizontal repair lines, parallel to the plurality of scan lines, the plurality of horizontal repair lines disposed on one side of the plurality of scan lines one to one; and a plurality of vertical repair lines, parallel to the plurality of data lines, the plurality of vertical repair lines disposed on one side of the plurality of data lines one to one; wherein a first horizontal repair line is selected from the plurality of horizontal repair lines while a first vertical repair line and a second vertical repair line are selected from the plurality of vertical repair lines, when one of the plurality of scan lines is detected to be a broken scan line, causing a pixel electrode unable to receive the scan signal; wherein a first cutting zone and a second cutting zone are formed on the first horizontal repair line, a third cutting zone and a fourth cutting zone are formed on the first vertical repair line, a fifth cutting zone and a sixth cutting zone are formed on the second vertical repair line, the first and second vertical repair lines are located between the first and second cutting zones, the first horizontal repair line and the broken scan line are located between the third and fourth cutting zones as well as between the fifth and sixth cutting zones, and the first and second vertical repair lines, respectively, are electrically connected to the broken scan line and the first horizontal repair line at their overlapping areas.
