Abstract

Disclosed is a touch liquid crystal display panel. According to one embodiment, the liquid crystal display panel comprises a thin film transistor array substrate, a color light filter substrate and a touch sensing layer. The thin film transistor array substrate comprises a plurality of pixel units. The color light filter substrate is arranged on the thin film transistor array substrate and comprises a transparent substrate, a color light filter and a transparent conducting layer. The transparent conducting layer is arranged between the transparent substrate and the color light filter and is electrically connected to reference voltage. According to the other embodiment, the liquid crystal display panel comprises the thin film transistor array substrate, the touch sensing layer, another color light filter substrate and another transparent conducting layer, wherein the transparent conducting layer is arranged between the touch sensing layer and the color light filter substrate and is electrically connected to reference voltage.

Description

technical field [0001] The present invention relates to a touch liquid crystal display panel, in particular to a touch liquid crystal display panel which can prevent the touch sensing effect from being disturbed by panel noise. Background technique [0002] In recent years, thin and light flat panel displays have become widely used displays for various electronic products. In order to achieve the purpose of convenience, simple appearance and multi-functionality, many information products have changed from traditional input devices such as keyboards or mice to touch panels (Touch Panel) as input devices. [0003] With the rapid development of the technology of flat-panel displays and touch input devices, in order to allow users to have larger visual images and provide more convenient operation modes in a limited volume, some electronic products combine touch panels and display panels. combined to form a touch display panel. Since the touch display panel has both the display...
