The touch display panel comprises a TFT array substrate (200) and a color film substrate (100) arranged opposite to each other. The TFT array substrate (200) comprises: a plurality of touch drive wires (TD), a plurality of touch sensing wires (TS), and a plurality of touch TFTs (220), one of the source (2053) and the drain (2054) of the touch TFTs (220) is electrically connected to the touch drive wires (TD), and the other one of the source (2053) and the drain (2054) of the touch TFTs (220) is electrically connected to the touch sensing wires (TS). The color film substrate (100) comprises: a plurality of conductive pillars (110) facing the TFT array substrate (200), and the conductive pillars (110) are arranged corresponding to the touch TFTs (220) to control the channel current of the touch TFTs (220). TFT arrays in the provided touch display panel and touch display device are compatible with the existing pixel array structure and technology, without adding additional process steps, and the realization of the touch function and the realization of the display function do not interfere with each other."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Touch display panel and touch display device","description":"Provided are a touch display panel and a touch display device.
