Abstract
An in-cell OLED touch display panel structure includes an upper substrate, a lower substrate, an OLED layer configured between the upper and lower substrates, and a black matrix layer. The black matrix layer is disposed at one surface of the upper substrate that faces the OLED layer, and the black matrix layer is composed of a plurality of opaque conductor lines. The plurality of opaque conductor lines is divided into a first group of opaque conductor lines, a second group of opaque conductor lines, and a third group of opaque conductor lines. The second group of opaque conductor lines is formed with N mesh-like polygonal regions. The opaque conductor lines in any one of the polygonal regions are electrically connected together, while any two polygonal regions are not connected, so as to form a single-layered touch sensing pattern on the black matrix layer.
