Abstract

The invention provides a touch panel. The touch panel includes a touch area, a metal mesh structure is arrange on the touch control area, the metal mesh structure includes touch electrodes and a dummyunit, the touch electrode includes a plurality of cell grids connected to each other, the dummy unit includes at least one first line, at least one second line, and an intersection formed by intersecting the first line and the second line. The dummy unit is arranged in the cell grid. The dummy unit has a gap distance between the dummy unit and the cell grid, and at least part of the dummy unit isarranged in the cell grid. The invention uniformizes the distribution of the capacitance by covering the whole touch area with the grid-shaped touch electrode; the dummy cell is arranged in the cellgrid of the touch electrode, so that the dummy cell is arranged dispersedly, and the influence when the touch electrode is short-circuited can be effectively reduced.

Description

technical field [0001] The present application relates to a touch technology, in particular to a touch panel. Background technique [0002] With the development of touch technology, touch panel technology has been applied in the field of display, such as touch display devices such as mobile phones, IPADs, and touch screens. [0003] The touch panel is arranged in the touch display device, and the touch panel includes a substrate, grid-shaped driving electrodes and grid-shaped sensing electrodes arranged on the substrate, and first grids arranged at intervals between the driving electrodes The second grid-like filling body and the second grid-like filling body arranged at intervals between the sensing electrodes; [0004] Wherein, the grid-like driving electrodes and the first grid-like filling body, and the grid-like sensing electrodes and the second grid-like filling body all form a metal grid structure. [0005] In metal grid structures, such as figure 1 , because elect...
