Abstract
A touch display panel and a touch display device are provided. They include a first substrate; and a first metal layer formed on one side of the first substrate. The first metal layer includes a plurality of touch electrode lines and a plurality of pressure sensing elements. The pressure sensing elements include segments of pressure sensing lines. At each crossing region where a touch electrode line comes across a pressure sensing element, two adjacent segments of pressure sensing lines are connected through a bridge. A second metal layer is formed between the first substrate and the first metal layer. The second metal layer includes a plurality of data lines extending along a first direction. A third metal layer is formed between the second metal layer and the first substrate. The third metal layer includes a plurality of scan lines extending along a second direction which is orthogonal to the first direction.
