Problems solved by technology
If touch signal lines and data lines are made of the same metal layer, then figure 1 The pixels 201, 202, 203, and 204 in the display need to be electrically connected to the data lines across the touch signal lines, so that there are structural differences between the pixels 201, 202, 203, and 204 and other pixels, resulting in uneven display.
If the touch signal line and the data line are arranged on different layers, it is necessary to add two masks for manufacturing the touch signal line layer and the connection via layer between the touch signal line and the common electrode, which increases the manufacturing cost , increasing the manufacturing process

The present application provides an array substrate and a display device. The array substrate includes a substrate and data lines, touch signal lines and conversion lines disposed on the substrate. The data lines include first data lines. The touch signal line and the first data line are arranged on the same layer. The touch signal lines and the first data lines are alternately arranged along the first row, and alternately arranged along the second row parallel to and opposite to the first row. The first data line on the first column is opposite to the touch signal line on the second column. The touch signal lines on the first column are opposite to the first data lines on the second column. The conversion line and the first data line are located on different layers. The conversion line connects the touch signal line on the first column to the touch signal line on the adjacent second column through the via hole, or connects the first data line on the first column to the adjacent second column through the via hole. The first data lines on the two columns are connected.
Description
technical field [0001] The present application relates to the technical field of touch display, and in particular, to an array substrate and a touch display panel. Background technique [0002] When the liquid crystal display panel is displaying, in order to avoid the polarization of the liquid crystal, the voltage applied to the pixel electrode needs to be alternately reversed relative to the common electrode, that is, the voltage of the pixel electrode is changed back and forth between positive and negative polarities. This technique is called inversion drive technique. When the voltage of the pixel electrode is higher than the voltage of the common electrode, it is called positive polarity (+), and when the voltage of the pixel electrode is lower than the voltage of the common electrode, it is called negative polarity (-). Inversion driving includes frame inversion, row inversion, column inversion and dot inversion. [0003] At present, dot inversion driving is the driv...
