Display device integrated with touch function and a driving method thereof

A driving method for a display device integrated with touch function and the display device comprising a display unit and a touch detection circuit and a plurality of shield layers, the display unit comprising a display region, the touch detection circuit comprising a touch detection unit and a reference unit,

• the touch detection unit comprising a plurality of touch driving electrodes and a plurality of touch sensing electrodes intersecting the plurality of touch driving electrodes, the plurality of touch driving electrodes and the plurality of touch sensing electrodes being located in the display region, and
• the reference unit comprising a plurality of reference electrodes which overlaps at least part of the plurality of touch driving electrodes of the touch detection unit, and are located in the display region, wherein each reference electrode corresponds to at least one touch sensing electrode, the plurality shield layers is in one-to-one correspondence to the plurality of reference electrodes, and are insulated from the plurality of reference electrodes, relative to the plurality of reference electrodes, the plurality of shield layers are closer to a touch side of the display device, in a direction perpendicular to the display region, each of the plurality of shield layers is disposed on a corresponding reference electrode of the plurality of reference electrodes, and overlaps at least part of the corresponding reference electrode,
• the method comprising:
• simultaneously driving a data refresh of the display unit and touch detection of the touch detection circuit, wherein a region for the data refresh and a region for the touch detection do not overlap at the same time period,
• wherein the touch detection comprises:
• providing a reference voltage signal by the plurality of reference electrodes, wherein the plurality of shield layers are configured to shield interference to the reference voltage signal from outside touch, such that the plurality of reference electrodes are not influenced by the outside touch;
• generating a plurality of touch result signals having interference of data driving removed according to the reference voltage signal.
