Abstract

The invention discloses a self-capacitance touch panel and a touch display panel, one or more redundant electrodes are connected in parallel on a signal transmission line of the self-capacitance touch panel, so that the routing impedance of the signal transmission line (especially for the signal transmission line connected with a self-capacitance touch electrode at a far end) is reduced; and the problems of incapability of driving touch control, high touch control power consumption, large touch control performance difference of different areas and the like caused by overlarge wiring impedance are solved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a self-capacitive touch panel and a touch display panel. Background technique [0002] With the rapid development of display technology, touch display panels are widely used in electronic products. Touch display panels include touch panels. Capacitive touch panels are one of the mainstream products at present. According to the touch principle, capacitive touch panels can be divided into self-capacitive touch panels and mutual-capacitive touch panels. , wherein the self-capacitive touch panel has the advantage of fast scanning speed and is suitable for single-point and gesture touch. [0003] The touch principle of the self-capacitive touch panel is as follows: the self-capacitive touch panel has an electrode array composed of a plurality of self-capacitive touch electrodes, and each self-capacitive touch electrode forms a capacitance with the ground. When using a cap...
