Abstract: An array substrate, a touch display panel, and a touch display device are provided. The array substrate includes a plurality of pressure sensors. Each pressure sensor includes a first input terminal electrically connected to a first power input terminal, and a second input terminal electrically connected to a second power input terminal. The array substrate also includes a first connection line between the first input terminal of each pressure sensor and the first power input terminal. The first connection line has a first line resistance. In addition, the array substrate includes a second connection line between the second input terminal of each pressure sensor and the second power input terminal. The second connection line has a second line resistance. Further, the array substrate includes a ratio of a resistance of each pressure sensor to a sum of the corresponding first line resistance and second line resistance is the same.
