Abstract

The present invention discloses a touch panel and a touch display panel, and the touch panel comprises driving lines and sensing lines crossing with each other, and in the extending direction of the driving lines, two line ends of each row/column of the driving lines having the largest distance therebetween are connected with a drive signal input line, and each row/column of the sensing lines is connected with a signal gathering line; and/or, in the extending direction of the sensing lines, two line ends of each row/column of the sensing lines having the largest distance therebetween are connected with a signal gathering line. The present invention achieves the following advantageous effects: through driving the touch panel bilaterally, or dividing the panel into a plurality of touch units, each touch unit is individually driven, which is equivalent to dividing a large-sized touch panel into small-sized touch panels; then the delay of the drive signal of the large-sized panel is improved, and the touch sensitivity is enhanced and the yield of the touch panel is also improved.
