Touch display panel having touch line formed on the same layer as the gate line

#The present disclosure claims priority of Chinese Patent Application No. 201810103497.8 filed on Feb. 1, 2018, the disclosure of which is hereby entirely incorporated by reference as a part of the present disclosure.

#Embodiments of the present disclosure relates to an array substrate and manufacturing method thereof, and a touch display panel.

#With the development of technology, touch panels have become more and more widely used. The touch panel provides a simple and convenient manner of human-computer interaction by replacing a mechanical button panel with a tactile feedback system. According to different combinations of the touch panel and the display structure, the touch panel can be divided into types of Add-on, On-Cell and In-Cell. The In-Cell touch screen has a touch electrode of the touch panel embedded in the display structure, which can reduce the overall thickness of the module, and can reduce the manufacturing cost of the touch screen, and thus has a significant advantage in the market.

#In order to clearly illustrate the technical solutions of the embodiments of the disclosure, the drawings of the embodiments will be briefly described in the following; it is obvious that the drawings described below are only related to some embodiments of the disclosure and thus are not limitative of the disclosure.

#FIG. 1 is an illustrative plan view of an array substrate;

#FIG. 2 is an illustrative plan view of an array substrate according to one embodiment of the present disclosure;

#In order to make objects, technical details and advantages of the embodiments of the disclosure apparent, the technical solutions of the embodiment will be described in a clearly and fully understandable way in connection with the drawings related to the embodiments of the disclosure. It is obvious that the described embodiments are just a part but not all of the embodiments of the disclosure. Based on the described embodiments herein, those skilled in the art can obtain other embodiment(s), without any inventive work, which should be within the scope of the disclosure.

#Unless otherwise defined, the technical terms or scientific terms used herein should have the common meaning as usually understood by those ordinary skilled in the art. The terms “first”, “second” and similar words used in the present disclosure do not denote any order, quantity, or importance, but are only used to distinguish different components. Similarly, the words of “a”, “an” or “the” are not intended to limit the number, but to indicate that there is at least one. Words like “including” or “comprising” and etc. mean that an element or an article before them contains an element or an article listed thereafter, while not excluding other elements or articles. Words such as “connect” or “couple” or the like are not to be limited to physical or mechanical connections, but can include electrical connections, either direct connections or indirect connections. Terms of “up”, “down”, “left”, “right” and etc. are only used to indicate relative positional relationships. When an absolute position of the described object is changed, the relative positional relationship may be changed accordingly.

#In a self-capacitance in-cell touch panel, in order to connect a touch electrode with a touch detection chip, a touch signal line correspondingly connected to the touch electrode is usually provided. The touch signal line can be separately fabricated by adding a mask process in addition to processes of preparing the array substrate for display, but this method leads to a complicated process and high production cost. The touch signal line can also be formed by the double-wiring method (that is, the display data line and the touch signal line are arranged in parallel on the same layer), however, this method reduces the aperture ratio of the pixel and degrades the display quality.
