US 10,310,682 B2 · Touch display panel and fabrication method thereof

Abstract

A touch display panel includes a top substrate, a bottom substrate, a first pressure sensing electrode, a second pressure sensing electrode and a liquid crystal layer. The top substrate has a color filter layer. The bottom substrate is stacked under the top substrate. The first pressure sensing electrode is disposed on a first surface of the top substrate. The second pressure sensing electrode is disposed on a surface of the bottom substrate. Therein, the first pressure sensing electrode and the second pressure sensing electrode form a pressure sensing capacitor. The liquid crystal layer is disposed between the top substrate and the bottom substrate and disposed between the first pressure sensing electrode and the second pressure sensing electrode.
