The invention discloses a touch substrate and a touch display device, the touch substrate comprises a touch structure layer arranged on a substrate, and the touch structure layer comprises a pluralityof first touch electrodes and a plurality of second touch electrodes; the touch structure layer comprises a metal grid; the metal grid comprises a plurality of grid patterns; the grid patterns are polygons formed by a plurality of metal wires, a plurality of first notches and a plurality of second notches are formed in the plurality of grid patterns, the plurality of first notches are located atboundary positions of the first touch electrodes and the second touch electrodes, and the plurality of second notches are located at other positions except the boundary positions; the first notches enable the metal wire to form a first broken line, and the second notches enable the metal wire to form a second broken line; in the plurality of grid patterns, the first broken line and the metal linesadjacent to the first broken line are a first broken line unit, the second broken line and the metal lines adjacent to the second broken line are a second broken line unis, and the form of the firstbroken line unit is different from that of the second broken line unit.
Description
technical field [0001] The embodiments of the present application relate to but are not limited to the field of display and touch technologies, and specifically relate to a touch substrate and a touch display device. Background technique [0002] With the rapid development of the active-matrix organic light-emitting diode (AMLOED) display industry, the display device is also developing towards narrower frame and thinner. At present, these high demands can be better realized by adopting flexible multi-layer integrated integrated touch technology (Flexible Multi Layer On Cell, FMLOC). When designing a display device using FMLOC technology, the touch structure layer is directly fabricated on the laminated light-emitting structure layer and packaging layer, which reduces the use of Optically Clear Adhesive (OCA) and does not need to drive the touch control layer. The flexible circuit board (Touch FPC, TFPC) connection can well realize the thinning and lightening of the product....
