Touch sensitive in-plane switching (IPS) liquid crystal display comprising an electric interference shielding layer attached onto a liquid crystal layer

摘要

A touch sensitive in-plane switching (IPS) liquid crystal display (LCD) includes a liquid crystal layer, an active-matrix transistor layer with an electrode pair, a color filter substrate, and a sensing electrode layer. The sensing electrode layer may be disposed above or below the color filter substrate, and the sensing electrode layer may include two parts that are disposed above and below the color filter layer respectively.

1. A touch sensitive in-plane switching (IPS) liquid crystal display (LCD), comprising:
a liquid crystal layer; an active-matrix transistor substrate disposed below the liquid crystal layer; an electrode pair disposed on the active-matrix transistor substrate wherein the electrode pair comprises a pixel electrode and a common electrode, wherein a laterally horizontal electric field is generated between the pixel electrode and the common electrode for controlling orientation of liquid crystals of the liquid crystal layer; a color filter substrate disposed above the liquid crystal layer; a sensing electrode layer disposed on a top surface of the color filter substrate; and a shielding layer disposed between the sensing electrode layer and the liquid crystal layer, wherein the shielding layer is attached onto the liquid crystal layer, wherein there is no other layer between the shielding layer and the liquid crystal layer, and the shielding layer is capable of preventing an electric interference between the liquid crystal layer and the sensing electrode layer.
