A touch display panel is provided with a display area and a non-display area surrounding the display area. It includes an array substrate and a color film substrate arranged opposite to each other. The array substrate includes, in the display area, multiple first touch electrodes extending along a first direction and arranged in sequence along a second direction. The color film substrate includes, in the display area, multiple second touch electrodes extending along the second direction and arranged in sequence along the first direction. A ratio of a coupling capacitance in a direction perpendicular to the array substrate between the first touch electrodes and the second touch electrodes positioned in the display area close to the non-display area to that between the first touch electrodes and the second touch electrodes positioned in the display area far from the non-display area falls in between 0.9 and 1.1.

Touch display panel and touch display device with balanced distribution of coupling capacitance and touch electrodes receive a common voltage signal

A touch control display panel and a touch control display device are provided. The touch control display panel comprises a plurality of first and second touch control sensing electrodes; a plurality of first and second touch control sensing signal lines; and a first integrated circuit. The first integrated circuit has a longer distance to the first touch control sensing electrode than to the second touch control sensing electrode. Rand Rsatisfy a predetermined relationship, such that touch control sensing signals respectively outputted by the first touch control sensing signal line and the second touch control sensing signal line exhibit substantially same signal delay time. Ris a total resistance of the first touch control sensing electrode and the electrically connected first touch control sensing signal line, and Ris a total resistance of the second touch control sensing electrode and the electrically connected second touch control sensing signal line.
