Abstract

The present application discloses a self-capacitance touch panel and a touch display panel. One or more of redundant electrodes are connected in parallel with each of signal transmission lines of the self-capacitance touch panel to reduce trace impedance of the signal transmission lines (especially for the signal transmission lines connected to self-capacitance touch electrodes at a far end). Problems of inability to drive touches, large touch power consumption, and marked incongruities in touch performance of different regions caused by excessive trace impedance are relieved.
