Abstract

The invention discloses a touch display panel and a manufacturing method thereof. The touch display panel comprises a substrate, a first metal layer, a TFT functional layer, and a common electrode layer, wherein the first metal layer comprises a touch line and light shielding blocks arranged on the substrate; the TFT functional layer is positioned on the first metal layer, and a first via hole isformed in the TFT functional layer; and the common electrode layer is positioned on the TFT functional layer and connected with the first via hole through the touch line. By virtue of the mode, the manufacturing cost can be lowered and the processing reliability can be improved.

Description

technical field [0001] The invention relates to the field of display panels, in particular to a touch display panel and a manufacturing method thereof. Background technique [0002] The touch type of the LTPS (Low Temperature Poly-silicon, low temperature polysilicon technology) display panel often adopts the self-inductance capacitive type, and the ITP (In Cell Touch Panel, embedded touch screen) is realized by integrating the sensor pad on the array substrate to improve the product quality. quality and value. The structure of the Sensor pad generally includes Common ITO and touch wire routing. The production of the touch line wiring can be designed separately, that is, the touch line wiring is set separately; the data line mask can also be used, that is, it is set on the same layer as the data line or formed by the same process, and is produced simultaneously with the same metal way, but both solutions have the problem of increased cost and process risk.
