Liquid crystal panel having notches for repair
View Patent ↗A liquid crystal panel of the present disclosure includes a first common electrode defining a plurality of first common electrode portions, a plurality of second common electrode portions connected to the first common electrode, and a plurality of pixel electrodes. Each pixel electrode overlaps one of the first common electrode portions and a corresponding one of the second common electrode portions, thereby forming storage capacitors therebetween. Each second common electrode portion defines a first notch adjacent to the pixel electrode. There is no overlap between the pixel electrode and the second common electrode portion at the first notch.
1. A liquid crystal panel comprising:
a plurality of gate lines parallel to each other; and
a plurality of data lines parallel to each other and extending perpendicular to the gate lines, the gate lines and data lines thereby defining a plurality of pixel regions, each pixel region comprising:
a common electrode comprising a first common electrode portion substantially parallel to the gate lines and a second common electrode portion substantially parallel to the data lines, the second common electrode portion electrically connected to the first common electrode portion; and
a pixel electrode; wherein the second common electrode portion comprises a first inner boundary adjacent to a corresponding data line and a first outer boundary opposite to the first inner boundary and adjacent to the pixel electrode, a portion of the first outer boundary is convex towards the first inner boundary such that a distance between the first inner boundary and the first outer boundary is at its narrowest at the convex portion, the pixel electrode overlaps the first common electrode portion and the second common electrode portion, thereby forming storage capacitors therebetween, and there is no overlap between the pixel electrode and the convex portion of the first outer boundary of the second common electrode portion.
2. The liquid crystal panel in claim 1 , wherein the pixel electrode comprises a second inner boundary adjacent to the second common electrode portion and a second outer boundary opposite to the second inner boundary, a portion of the second inner boundary is convex towards the second outer boundary to allow the pixel electrode to have a narrower distance between the second inner boundary and the second outer boundary at the convex portion of the second inner boundary than a distance between the second inner boundary and the second outer boundary at other portions of the second inner boundary, the convex portion of the second inner boundary corresponding to the convex portion of the first outer boundary.
3. The liquid crystal panel in claim 2 , wherein the second common electrode portion is connected with the first common electrode portion at a first connection point, the first convex portion being adjacent to the first connection point.
4. The liquid crystal panel in claim 3 , wherein in each pixel, the common electrode further comprises a third common electrode portion, the third common electrode portion being connected with the first common electrode portion at a second connection point, the third common electrode portion and the second common electrode portion being symmetrically opposite each other across a width of the pixel, the pixel electrode overlapping the third common electrode portion thereby forming a storage capacitor therebetween.
5. The liquid crystal panel in claim 4 , wherein the third common electrode portion comprises a third inner boundary adjacent to the second common electrode portion and a third outer boundary opposite to the third inner boundary, a portion of the third inner boundary is convex towards the third outer boundary to allow the third common electrode portion to have a narrower distance between the third inner boundary and the third outer boundary at the convex portion of the third inner boundary than a distance between the third inner boundary and the third outer boundary at other portions of the third inner boundary, with there being no overlap between the pixel electrode and the convex portion of the third inner boundary of the third common electrode portion.
6. The liquid crystal panel in claim 5 , wherein a portion of the second outer boundary is convex towards the second inner boundary to allow the pixel electrode to have a narrower distance between the second inner boundary and the second-outer boundary at the convex portion of the second outer boundary than a distance between the second inner boundary and the second outer boundary at other portions of the second outer boundary without the convex portion, the convex portion of the second outer boundary corresponding to the convex portion of the third inner boundary.
