Touch display panel and a touch control circuit

A touch control circuit configured to control a touch display panel, the touch display panel comprising a substrate, a first touch sensor layer, disposed on the substrate and patternized into a plurality of blocks for serving as a plurality of first touch sensor electrodes, wherein the first touch sensor electrodes are grouped into a plurality of touch sensor units, each touch sensor unit comprising one or more first touch sensor electrodes, and a display electrode layer, disposed between the substrate and the touch sensor layer and serving as one or more display electrodes, and the touch display panel further comprising a plurality of display pixels, each display pixel comprising at least one organic light-emitting diode, wherein the organic light-emitting diode has a first end and a second end, and at least one of the first end and the second end is formed by one of the one or more display electrodes, the touch control circuit comprising:

• a first control circuit configured to provide a first driving signal to at least one of the one or more first touch sensor electrodes of each touch sensor unit, the at least one of the one or more first touch sensor electrodes is configured to serve as a transmitting electrode during a touch sensing period;
• and
• a second control circuit configured to set at least one of the one or more display electrodes in a state capable of reducing effect of parasitic capacitances between a currently-driven-for-sensing touch sensor unit and the at least one of the one or more display electrodes.
