Abstract

The invention discloses an array substrate, a touch display panel and a touch display device. According to one embodiment, the array substrate comprises a substrate body, a plurality of metal layers, a touch control electrode layer and a plurality of touch control signal lines, wherein the substrate body has a display area and a non-display area, the metal layers are perpendicular to the substrate body and include the first metal layers and the second metal layers, the first metal layers are used for forming scanning lines of the array substrate, and the second metal layers are used for forming data lines of the array substrate; a plurality of pixel units are arranged in the display area and distributed into an array, the line direction of the pixel units is the extending direction of the scanning lines, and the row direction of the pixel units is the extending direction of the data lines; the touch control electrode layer comprises a plurality of touch control electrodes, the touch control signal lines are electrically connected with one touch control electrode and used for transmitting touch control signals to the touch control electrode, and the touch control signal lines and at least one metal layer are located on the same layer. In this way, the complexity of the manufacturing process of the array substrate can be reduced.

Description

technical field [0001] The present application relates to the field of display technology, in particular to the field of touch display technology, especially to an array substrate, a touch display panel and a touch display device. Background technique [0002] Common electrodes are arranged on the embedded touch display screen. During touch detection, the common electrode is multiplexed as a touch emission electrode to receive a touch driving signal, and the touch detection circuit determines a touch point according to a change in capacitance on the display screen. The common electrode can be made of ITO conductive glass. In the in-cell touch display panel, the common electrodes on the touch display panel are arranged in strips in parallel. Since the area of ​​the common electrode is relatively large, its resistance value is relatively high, which greatly affects the accuracy of the touch detection circuit. [0003] Generally, an in-cell touch display screen may include m...
