Problems solved by technology
[0002] In touch products such as touch and display driver integration (Touch and Display driver Integration, TDDI), it is easy to generate touch due to the excessive resistance of the transparent touch electrode and the low signal strength of the received touch signal. poor control
For example, touch electrodes covering a display area of 5×5 mm generally need to export the collected touch signals to external chips through metal leads, because the number of metal leads cannot be densely arranged due to the limitation of the aperture ratio, and the distance between the touch electrodes The touch signal generated at a relatively distant position of the metal lead will have considerable signal attenuation during transmission, so there is a problem that the local touch signal is easily covered by noise, resulting in related bad touch

The disclosure provides an array substrate, a manufacturing method thereof, and a display device, which belong to the display field. The array substrate includes a display area and a peripheral circuit area, and the array substrate also includes: several touch electrodes located in the display area; several strips connecting the several touch electrodes to the peripheral circuit area Touch signal lines; a plurality of first conductor lines extending in the same direction as the plurality of touch signal lines; and a plurality of second conductor lines extending in a direction different from the plurality of touch signal lines; wherein, each The first conductor line is connected to the touch electrode in the thickness direction of one touch electrode; each second conductor line corresponds to a touch electrode, and any second conductor line is connected to the corresponding touch electrode. The touch signal line connected to the control electrode, and any second conductor line is respectively connected to each first conductor line connected to the corresponding touch electrode. The disclosure helps to improve the signal strength of the touch signal received by the substrate.

technical field [0001] The present disclosure relates to the display field, and in particular to an array substrate, a manufacturing method thereof, and a display device. Background technique [0002] In touch products such as touch and display driver integration (Touch and Display driver Integration, TDDI), it is easy to generate touch due to the excessive resistance of the transparent touch electrode and the low signal strength of the received touch signal. Poor control. For example, touch electrodes covering a display area of 5×5 mm generally need to export the collected touch signals to external chips through metal leads, because the number of metal leads cannot be densely arranged due to the limitation of the aperture ratio, and the distance between the touch electrodes The touch signal generated at a relatively distant position of the metal lead will have considerable signal attenuation during transmission, so there is a problem that the local touch signal is easily...
