Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0042] figure 1 It is a schematic diagram of a partial structure of an array substrate provided by an embodiment of the present invention. see figure 1 , the array substrate includes a plurality of data lines D (for example figure 1 D1~D15 in), multiple touch wires M (for example figure 1 M1-M5 in ) and a plurality of touch electrodes S (each dotted box represents a touch electrode S). Each touch electrode S is connected to at least one touch wire M, and each touch electrode S is connected to a different touch wire M. The array substrate also includes a plurality of switch units ( figure 1 not shown). Each switch unit is connected to a data line D, and each switch unit is configured to electrically connect the connected data line...

Abstract

The invention discloses an array substrate and a manufacturing method thereof, a touch display device and a driving method thereof, and belongs to the field of display technology. The array substrate includes multiple data lines, multiple touch lines, multiple touch electrodes and multiple switch units. Each of the touch electrodes is connected to at least one of the touch lines, each switch unit is connected to one of the data lines, and each of the switch units is configured to selectively connect the connected data lines. The wire is electrically connected to one of the touch electrodes. The array substrate can use the data lines to provide touch signals to the corresponding touch electrodes in the touch stage. Therefore, the resistance of the touch lines can be reduced without widening the touch lines, which is beneficial to increase the aperture ratio of the product.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate and a manufacturing method thereof, a touch display device and a driving method thereof. Background technique [0002] At present, in order to realize the thinning and lightening of the touch panel, the research on the integration of the touch panel and the liquid crystal display panel is becoming more and more popular. Among them, an in-cell (In-Cell) touch solution in which a touch panel is embedded in a liquid crystal display panel has attracted widespread attention. The In-Cell touch solution mainly includes two methods of self-capacitance touch and mutual-capacitance touch. [0003] In the self-capacitance touch mode, the touch display panel usually multiplexes the common electrodes and the touch electrodes. This touch display panel includes a plurality of touch electrodes distributed in a matrix, and each touch electrode is connected to a touch...
