Abstract
The present application provides a touch electrode structure and a touch display panel, wherein the first touch electrodes include a plurality of main electrodes connected end to end along a first direction and continuously conducted and branch electrodes connected to the main electrodes, each of the branch electrodes includes a first branch portion and a second branch portion which are arranged crosswise; and a plurality of second touch electrodes, such that the RC delay of the first touch electrodes is effectively reduced, the time required for screen scanning is reduced, and the touch report rate is thereby effectively increased.
Claims18
A touch electrode structure, comprising:
- a plurality of first touch electrodes arranged in parallel, wherein the first touch electrodes comprise a plurality of main electrodes connected end to end along a first direction and continuously conducted and branch electrodes connected to the main electrodes, each of the branch electrodes comprises a first branch portion and a second branch portion, the first branch portion is connected to one of the main electrodes, the second branch portion is cross-connected to the first branch portion without contacting the main electrodes;
- and
- a plurality of second touch electrodes arranged in parallel, wherein the second touch electrodes are continuously conducted along a second direction, the second touch electrodes are arranged around the branch electrodes and the main electrodes, and electrically insulated from the first touch electrodes, wherein the second direction and the first direction are perpendicular to each other, and the first touch electrodes and the second touch electrodes intersect each other to form a plurality of repeatedly arranged touch units;
- wherein the touch electrode structure further comprises a first floating electrode disposed between adjacent ones of the second touch electrodes to electrically isolate adjacent ones of the second touch electrodes, and the first floating electrode is electrically insulated from the second touch electrodes and the first touch electrodes;
- wherein a width of the first floating electrode is greater than a width of one sub-pixel and less than or equal to a maximum distance between two adjacent sub-pixels.
