Touch structure, touch detection method and touch display device

Abstract

The invention discloses a touch structure, a touch detection method and a touch display device. The touch structure is internally provided with a first strip electrode and a second strip electrode, which are intersected and are arranged in different layers, wherein the first strip electrode comprises a first strip sub-electrode and a second strip sub-electrode which are in mutual isolation and are arranged in the same layer. When the touch structure is adopted to perform touch detection, in an initial detection mode, the first strip sub-electrode is taken as a touch drive electrode and the second strip sub-electrode is taken as a touch detection electrode, so that touch detection is realized when only the single-layer touch electrode is in an operating state; when touch is detected under the initial detection mode, a fine detection mode can be started, the second strip sub-electrode is taken as a touch drive electrode and at least part of the first strip electrode is taken as a touch detection electrode; or the second strip electrode is taken as a touch detection electrode and at least part of the first strip electrode is taken as a touch drive electrode, so that fine detection on the touch position is realized.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to a touch structure, a touch detection method and a display device. Background technique [0002] With the rapid development of display technology, touch screen panels (Touch Screen Panels) have gradually spread in people's lives. At present, touch screens can be divided into: resistive, capacitive, infrared, surface acoustic wave, electromagnetic, vibration induction, and frustrated total internal reflection optical induction, etc. according to their working principles. Among them, the capacitive touch screen is sought after by the industry as a new favorite due to its unique touch principle, high sensitivity, long life, high light transmittance and other advantages. [0003] At present, the existing capacitive touch screen uses the principle of mutual capacitance to detect the touch position of a finger; wherein, generally, a pattern of a touch structure is added to the t...

AI Technical Summary

Problems solved by technology

[0004] The above touch structure has the following problems in actual work: the touch position can only be detected when the touch detection electrodes on the side facing the substrate and the touch drive electrodes on the array substrate work simultaneously, and only when the touch When the control and detection electrodes are in the working state, for example, when the mobile phone using the touch screen is in the dormant state, the touch screen does not actually perform display work, that is, the driver chip driving the array substrate is in a dormant state and stops working. At this time, no signal is generated on the array substrate. , so that no signal is loaded on the touch drive electrodes located on the side of the array substrate, and the touch detection cannot be realized. Only when the touch screen is triggered to resume display work, can the touch detection be realized
