Single-layer capacitive touch sensor and touch control terminal

A single-layer capacitive touch sensor, comprising a substrate, wherein the substrate is distributed with:

• several induction electrodes arranged in a first direction, wherein the induction electrodes comprise induction electrode blocks distributed in the first direction and several induction electrode extension parts extended from the induction electrode blocks on a same side of the induction electrode blocks in a second direction, the first direction is perpendicular with the second direction, and induction electrode extension parts of adjacent induction electrodes are extended in opposite directions;
• several drive electrodes arranged in the second direction, wherein each row of drive electrodes comprise drive electrode units, the number of which is the same as the number of columns of induction electrodes, the drive electrode units comprise drive electrode blocks distributed in the first direction and several drive electrode extension parts extended from the drive electrode blocks on a same side of the drive electrode blocks in a direction opposite to the second direction, so that the drive electrode extension parts are interlocked with the corresponding induction electrode extension parts;
• and
• several ground electrodes arranged in the first direction and located between saturated surfaces of adjacent induction electrodes.
