Claim Text:
1. A liquid crystal display panel, comprising an array substrate and a color filter substrate, in which liquid crystal is filled between the array substrate and the color filter substrate, the array substrate includes a pixel electrode, and the color filter substrate includes a common electrode corresponding to the pixel electrode, wherein: the common electrode stores charges when an external object carrying static electricity touches a display region of the liquid crystal display panel, and thus a potential difference is formed between the pixel electrode of the array substrate and respective touch points, contacting with the external object, in the display region of the liquid crystal display panel, so that the liquid crystal between the touch point and the pixel electrode is deflected according to the formed potential difference, wherein the color filter substrate further comprises at least one common electrode switch for controlling electrical connection and disconnection of the common electrode with a power supply, wherein when the common electrode switch is switched off, the liquid crystal display panel is used as a demonstration board which is capable of displaying dynamically depicted graphs; when the common electrode switch is switched on, there is no potential difference between the common electrode and the pixel electrode, and the liquid crystal filled between the common electrode and the pixel electrode is not deflected, so that the graphs dynamically depicted on the liquid crystal display panel are removed or the liquid crystal display panel is used for displaying images.
