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.

First claim

What is claimed is:

1. An in-cell OLED touch display panel structure, 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 and facing the OLED layer, the black matrix layer being composed of a plurality of opaque conductor lines; and
a thin film transistor layer disposed at the surface of the lower…
