In-Cell Touch Display Panel Structure with Metal Layer on Lower Substrate for Sensing

Abstract

An in-cell touch display panel structure with metal layer on lower substrate for sensing includes an upper substrate, a lower substrate, a liquid crystal layer, a black matrix layer and a thin film transistor and sensing electrode layer. The upper substrate and the lower substrate are in parallel with each other and the liquid crystal layer is configured between the upper substrate and the lower substrate. The black matrix layer is disposed at one surface of the upper substrate, and is composed of a plurality of opaque lines. The thin film transistor and sensing electrode layer is disposed at one surface of the lower substrate, and includes a plurality of scanning lines, a plurality of data lines, and a plurality of sensing conductor lines. The plurality of sensing conductor lines is disposed corresponding to positions of the plurality of opaque lines of the black matrix.
