摘要： The disclosure provides a touch module, a touch display panel and a display device. Each touch electrode includes a plurality of electrode blocks arranged along an extending direction, and electrode blocks belonging to other touch electrodes are distributed in an area where at least part of all the electrode blocks are located, which makes full use of an interior area of a traditional touch pattern and increases a coupling area between the touch electrodes. When touch occurs, an amount of change in a mutual capacitance value between the touch electrodes will be significantly increased, thereby increasing touch sensitivity.
