Abstract

The invention provides a touch control display panel and a touch control display device. The touch control display panel includes a touch control electrode block and a touch control signal line which is correspondingly connected with the touch control electrode block through a bridge structure; the touch control signal line includes a first part located in a display region and a second part located in an non-display region, an auxiliary bridge structure is arranged on the second part of the touch control signal line, impurity ions diffused from self-sealing frame adhesive are firstly diffused to the non-display region in which the auxiliary bridge structure is located, ionic pollution generated by the frame sealing adhesive is solved, the number of the impurity ions entering the display region is reduced, and accordingly the line blur phenomenon of the touch control display panel is further improved.

Description

technical field [0001] The present invention relates to the technical field of touch display, and in particular to a touch display panel and a touch display device. Background technique [0002] With the rapid development of display technology, touch display devices have gradually spread in people's daily life. At present, existing in-cell touch display devices use the principle of mutual capacitance or self-capacitance to detect the position touched by a finger. Among them, using the principle of self-capacitance, a plurality of self-capacitance electrodes arranged on the same layer and insulated from each other can be arranged in the touch display device. When the human body touches the screen, the capacitance borne by the corresponding self-capacitance electrodes is a fixed value superimposed on the human body capacitance. The integrated circuit for touch control in the drive unit can judge the touch control by detecting the capacitance value changes of the respective ca...
