Abstract:
1. An in-cell touch display panel structure with metal layer on lower substrate for sensing, comprising: an upper substrate; a lower substrate parallel to the first substrate; a liquid crystal layer configured between the upper substrate and the lower substrate; a black matrix layer disposed at one surface of the upper substrate facing the liquid crystal layer, the black matrix layer being composed of a plurality of opaque lines; and a thin film transistor and sensing electrode layer disposed at one surface of the lower substrate facing the liquid crystal layer, the thin film transistor and sensing electrode layer including a plurality of scanning lines, a plurality of data lines, and a plurality of sensing conductor lines, wherein the plurality of sensing conductor lines are disposed corresponding to positions of the plurality of opaque lines of the black matrix; wherein the plurality of scanning lines and the plurality of data lines are disposed corresponding to the positions of the plurality of opaque lines of the black matrix, and the plurality of sensing conductor lines are disposed at one surface of the plurality of scanning lines and the plurality of data lines facing the liquid crystal layer; wherein the plurality of sensing conductor lines are divided into a first group of sensing conductor lines and a second group of sensing conductor lines, the first group of sensing conductor lines being formed to be N quadrilateral regions, where N is a positive integer, the sensing conductor lines in any one of the quadrilateral regions being electrically connected together while the sensing conductor lines in any two quadrilateral regions are not electrically connected, so as to form a single-layered touch pattern on the thin film transistor and sensing electrode layer.
