Abstract
A touch-type display panel includes an array substrate including a plurality of sub-pixels defined by gate lines and data lines; a plurality of touch electrodes disposed to cover the sub-pixels; two or more touch driving lines that electrically connect a touch driving circuit to a respective one of the touch electrodes; and a connection line disposed on both sides of the one of the touch electrodes and configured to electrically connect the two or more touch driving lines.
Claims13
A touch-type display panel, comprising:
- an array substrate including:
- a plurality of sub-pixels defined by gate lines and data lines;
- a plurality of touch electrodes disposed to cover the sub-pixels;
- two or more touch driving lines that electrically connect a touch driving circuit to a respective one of the touch electrodes;
- and
- a connection line disposed on both sides of the one of the touch electrodes and configured to electrically connect the two or more touch driving lines.
A short-repair method of a touch-type display panel including an array substrate on which a plurality of touch electrodes, a touch driver, two or more touch driving lines electrically connecting the touch driver to a respective one of the touch electrodes, and a connection line disposed on both sides of the one of the touch electrodes and electrically connecting the two or more touch driving lines, the short-repair method comprising:
- sensing a short in which one of the touch driving lines corresponding to the one of the touch electrodes is electrically connected to another touch electrode;
- and
- cutting the shorted touch driving line from both sides of the other shorted touch electrode.
A touch-type display panel, comprising:
- an array substrate including:
- a plurality of sub-pixels defined by gate lines and data lines;
- a plurality of touch electrodes disposed to cover the sub-pixels;
- a first touch driving line and a second touch driving line electrically connecting a touch driving circuit to a respective one of the touch electrodes;
- and
- a connection line disposed on both sides of the one of the touch electrodes and configured to electrically connect the first and second touch driving lines,
- wherein the array substrate includes a short in which the first touch driving line corresponding to the one of the touch electrodes is electrically connected to another touch electrode, and
- wherein the shorted first touch driving line is cut from both sides of the another touch electrode such that the entire second touch driving line, a remaining part of the first touch driving line other than the cut part of the first touch driving line, and a connection line disposed on both sides of the other touch electrode are electrically connected to each other and the cut part of the first touch driving line is electrically floated.
