TOUCH DISPLAY PANEL

摘要

A touch display panel is provided herein, which comprises an array substrate, a color filter substrate, and a liquid crystal layer. A touch driving electrode is disposed on the array substrate. A first polarizer is disposed at an outer side of the array substrate. A second polarizer is disposed at an outer side of the color filter substrate. The second polarizer has a touch sensing electrode manufactured on an outer surface thereof. In the present invention, the touch sensing electrode is disposed on the polarizer or the cover plate, thereby avoiding fragmentation of the substrates and further improving the product yield rate of the touch display panel.

1. A touch display panel, comprising an array substrate, a color filter substrate, and a liquid crystal layer disposed between the array substrate and the color filter substrate, wherein the touch display panel further comprises:
a touch driving electrode disposed on the array substrate; a first polarizer disposed at an outer side of the array substrate; a second polarizer disposed at an outer side of the color filter substrate, the second polarizer having a touch sensing electrode manufactured on an outer surface thereof; and a cover plate disposed at an outer side of the second polarizer; wherein the touch display panel further comprises a driving chip, the driving chip provides a common voltage signal for the touch driving electrode when the touch display panel is in a display mode, and the driving chip provides a driving signal for the touch driving electrode when the touch display panel is in a touch control model; wherein the array substrate has a transparent electrode layer manufactured on an inner surface thereof, and the touch driving electrode is formed by pattering the transparent electrode layer.
