Abstract
The disclosure provides an array substrate and a method of manufacturing the same, a display device and a method of detecting a touch position. In the array substrate, the plurality of X and Y sensing lines are respectively parallel to gate data lines, and a sensing thin film transistor is provided at a crossing position where the X and Y sensing lines cross. A control terminal and an output terminal of the sensing thin film transistor are coupled to the X and Y sensing lines, respectively. A piezoelectric material layer is formed between the control terminal and an input terminal of the sensing thin film transistor such that, when being pressed, the piezoelectric material layer generates deformation such that a sensing voltage is generated at the input terminal of the sensing thin film transistor with relative to the control terminal of the sensing thin film transistor.
