Display devices
View Patent ↗Techniques of effective and continuous signal transmission in a display device are described. Techniques of the present subject matter allow lead-out lines of the display device to provide continuous transmittance of signals to data/gate lines. In an example, the display device may include a plurality of pixels arranged in a first direction and a second direction in a matrix arrangement, and a plurality of first lines extending in the first direction and a plurality of second lines extending in the second direction. Further, the display device may also include a plurality of lead-out lines extending in the first direction, such that, a lead-out line from the plurality of lead-out line overlaps a second line from the plurality of second lines to form an overlap region, where, the lead-out lines may be electrically connected to the second lines through a plurality of contact points in the overlap region.
1. A display device comprising:
a plurality of sub-pixels arranged in a first direction and a second direction in a matrix arrangement;
a plurality of first lines extending in the first direction;
a plurality of second lines extending in the second direction;
a plurality of lead-out lines extending in the first direction; and
a plurality of overlap regions, an overlap region from the plurality of overlap regions where a lead-out line from the plurality of lead-out lines and a second line from the plurality of second lines overlap in plan view, wherein
the lead-out line electrically connects to the second line through two or more contact holes formed in the overlap region, the two or more contact holes being formed in an insulating layer between the lead-out line and the second line and being aligned in the first direction,
the second line has an extended portion extending in the first direction and overlapping the lead out line in the overlap region,
at least one of the two or more contact holes overlaps the extended portion, and
the second line is a gate line and the extended portion extends towards both opposite sides of the display device.
2. The display device as claimed in claim 1 , wherein the lead-out line is a gate lead-out line.
3. The display device as claimed in claim 2 , further comprises a gate driver placed at a first side of the display device, wherein
the gate driver electrically connects to the gate line via the gate lead-out line.
4. The display device as claimed in claim 1 , wherein the second line has an extended portion formed in the overlap region, the extended portion being wider in the first direction than a middle portion of the second line formed between two adjacent overlap regions.
5. The display device as claimed in claim 4 , wherein the second line is a gate line and the extended portion extends towards both opposite sides of the display device.
6. The display device as claimed in claim 1 , wherein the second line has a cross shape formed in the overlap region.
7. The display device as claimed in claim 1 , wherein the lead-out line electrically connects to a conductive patch formed between two adjacent overlap regions from the plurality of overlap regions via a plurality of through holes formed in an insulating layer between the lead-out line and the conductive patch, wherein the conductive patch extends in the first direction.
8. The display device as claimed in claim 7 , wherein each through hole from the plurality of through holes is located overlapping a distal end of the conductive patch in plan view.
9. The display device as claimed in claim 1 , wherein the first line from the plurality of first lines is a data line, and wherein the lead out line is formed in a same layer of the data line.
10. The display device as claimed in claim 1 , wherein the extended portion is wider in the first direction than a middle portion of the second line formed between two adjacent overlap regions.
