Abstract

An array substrate and its manufacturing method, and a touch display device are disclosed. A display area of the array substrate includes a plurality of thin film transistor (11), first transparent electrodes (12), second transparent electrodes (13) and a transparent insulation layer (16) that contacts the second transparent electrodes (13); the transparent insulation layer (16) is a conductor when a voltage applied thereon is larger than a predetermined voltage, and is an insulator when the voltage applied therein is less than the predetermined voltage. The second transparent electrodes (13) include first sub-electrodes (131) arranged into a plurality of rows in a first direction and insulated from each other, and second sub-electrodes (132) arranged into a plurality of rows in a second direction and insulated from each other, the first direction is intersected with the second direction. The problems such as noise, visual artifacts, insensitive to touch, or the like caused by unbalance of charges can be avoided.

Description

technical field [0001] The present invention relates to the technical field of touch display, in particular to an array substrate, a preparation method, and a touch display device. Background technique [0002] With the rapid development of display technology, the birth of a touch panel (TP for short) makes people's lives more convenient. [0003] The touch screen includes an add-on touch screen (Add On Touch Panel) and an embedded touch screen (In Cell Touch Panel). Among them, the structure of the plug-in touch screen is to bond the touch panel and the display panel together. This technology has disadvantages such as high production cost, low light transmittance, and thick module. Therefore, with the development of technology With the development of the industry, the embedded touch screen has gradually become the new darling of research and development. [0004] At present, the touch sensing method of the in-cell touch screen is mainly mutual capacitance, and the mutual-...
