The touch display panel comprises an array substrate and a colored film substrate which are oppositely arranged, the colored film substrate comprises a plurality of sensing electrodes distributed in a line direction, and the array substrate comprises a plurality of driving electrodes and driving electrode connecting wires distributed in a row direction and a plurality of driving electrode wires distributed in the line direction; each row of driving electrodes comprises a plurality of driving electrode blocks, each driving electrode block is connected with a driving electrode wire, and the driving electrode blocks in different rows are connected with different driving electrode wires; each driving electrode block comprises a plurality of driving electrode units distributed in a spaced manner, and the driving electrode units of each driving electrode block are electrically connected through the driving electrode connecting wires; the orthographic projection of each of the driving electrode wires connected with each driving electrode block is not overlapped with the orthographic projection of the driving electrode units of other driving electrode blocks except the driving electrode block.

Description

technical field [0001] The present invention relates to the field of touch and display technologies, and in particular to a touch display panel, a manufacturing method thereof, and a touch display device. Background technique [0002] With the rapid development of display technology, touch display panels (Touch Panel) have gradually spread in people's lives. Compared with the traditional display that can only provide display functions, the display using the touch display panel can enable information interaction between the user and the display control host. Therefore, the touch display panel can completely or at least partially replace the common input device , so that the existing display can not only display, but also touch control. At present, the most widely used touch display panel is the capacitive touch display panel. The capacitive touch display panel is divided into internal Embedded (in-cell), external embedded (on-cell) and plug-in three. Among them, the embedd...

Problems solved by technology

[0004] In this design method of the prior art, in the touch stage, since the metal traces in the inner touch drive electrodes will cross the electrode blocks in the outer touch drive electrodes, such as: the metal traces in the touch drive electrodes Tx2 132 across the electrode block 12 in the touch driving electrode Tx1, so that when the touch scanning is performed on the inner touch driving electrode, the outer touch driving electrode will be subject to crosstalk, affecting the overall touch uniformity of the touch display panel

In addition, in the prior art, if the leads 141 forming the touch driving electrodes Tx1 and the leads 142 forming the touch driving electrodes Tx2 are made on the same layer, a short circuit will occur. Therefore, in the actual manufacturing process, the leads 141 and 142 need to be made on Different layers, or when the lead wire 141 and the lead wire 142 are made on the same layer, an insulation setting is required at the crossing position of the lead wire 141 and the lead wire 142

[0005] To sum up, the touch display panel of the prior art is prone to crosstalk during the touch stage, and the overall touch uniformity of the touch display panel is poor.
