An array substrate and a preparation method, touch display device

Example embodiments provide an array substrate and a method of preparation of the present invention, the touch display apparatus, technical field relates to a touch display, can solve the prior art due to the noise generated by the charge imbalance, touch-insensitive visual artifacts and problems. Display region of the array substrate includes a plurality of thin film transistors disposed on a base substrate, a first transparent electrode, a second transparent electrode; further comprising a transparent insulating layer in contact with the second transparent electrode; transparent insulating layer material is a composite material when applied to a transparent insulating layer is greater than a preset voltage voltage conductor transparent insulating layer, a transparent insulating layer is less than a preset voltage insulator; wherein the second transparent electrode comprises a first sub-plurality of rows arranged along a first direction of electrodes arranged in a plurality of rows along a second direction, a second sub-electrodes; insulated from each other between the different rows of the first sub-electrodes, insulated from each other between the different rows of the second sub-electrode, and the first sub-electrode and a second sub-electrodes insulated from each other ; first and second directions intersect.
