Claim Text:
1. An in-cell OLED touch display panel structure with metal layer for sensing, comprising: an upper substrate; a lower substrate parallel to the upper substrate; an OLED layer configured between the upper substrate and the lower substrate; a black matrix layer disposed at one surface of the upper substrate facing the OLED layer, the black matrix layer being composed of a plurality of opaque lines; a sensing electrode layer disposed at one side of the black matrix layer facing the OLED layer, the sensing electrode layer being composed of a plurality of sensing conductor lines; and a thin film transistor layer disposed at one side of the lower substrate facing the OLED layer, wherein the plurality of sensing conductor lines are disposed at positions corresponding to those of the plurality of opaque lines of the black matrix; 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 mesh-like polygonal regions as sensing electrodes, where N is a positive integer, the sensing conductor lines in any one of the mesh-like polygonal regions being electrically connected together while the sensing conductor lines in any two mesh-like polygonal regions are not electrically connected, so as to form a single-layered touch pattern on the sensing electrode layer; wherein the second group of sensing conductor lines is formed to be N conductive traces, each of the N conductive traces being electrically connected to a corresponding mesh-like polygonal region, while any two conductive traces are not electrically connected.
