Embodiment Construction

[0031] In order to further illustrate the touch display substrate, touch display device and touch display method provided by the embodiments of the present invention, a detailed description will be given below in conjunction with the accompanying drawings.

[0032] see figure 1 , as described in the background art, in the prior art, since the edge line 2 located in the non-touch area of ​​the touch display substrate is opposite to the black matrix 3 on the opposite substrate, when the touch display device works in the touch period, The first parasitic capacitance C1 will be generated between the edge line 2 and the black matrix 3, and the second parasitic capacitance C2 will be generated between the black matrix 3 and the transparent conductive electrode 5 at the same time, so that the first parasitic capacitance C1 and the second parasitic capacitance C2 A coupling effect easily occurs between them, causing the electrical signal on the transparent conductive electrode 5 to be...

Abstract

The invention discloses a touch display substrate, a touch display device and a touch display method, and relates to the technical field of display touch. The touch display substrate, the touch display device and the touch display method aim at solving the problem that an electric signal on a transparent conductive electrode is likely to be pulled by an electric signal on an edge line, and consequently the touch performance stability is influenced. The touch display substrate comprises an underlayer, a thin film transistor array layer, a first transparent conductive electrode and a second transparent conductive electrode, and the thin film transistor array layer, the first transparent conductive electrode and the second transparent conductive electrode are arranged on the underlayer in sequence. In a display time period, the second transparent conductive electrode serves as a common electrode, in a touch time period, the second transparent conductive electrode is reused as a touch electrode, and the edge line is arranged in a non-touch area of the touch display substrate. The touch display substrate further comprises a shielding layer covering at least part of the edge line. The touch display substrate is used for achieving a touch function and a display function.

Description

technical field [0001] The present invention relates to the field of display touch technology, in particular to a touch display substrate, a touch display device and a touch display method. Background technique [0002] With the continuous development of display technology, touch display devices are more and more widely used. Touch display devices integrate touch panels and display panels. When users use touch display devices, they can directly input or The control operation makes the application of the touch display device more convenient. [0003] In order to make the touch display device thinner, the research direction of embedding the touch panel function into the display panel (In-cell type) has gradually become the focus. The touch display panel of the In-cell touch display device generally includes: The touch display substrate and the color film substrate are arranged oppositely, wherein the touch display substrate is provided with a transparent conductive electrode,...
