Embodiment 1

[0035] see figure 1 , the touch display device 10 provided in this embodiment includes a touch structure 20 , a display panel 30 and a cover plate 40 . Wherein, in this embodiment, the touch structure 20 is stacked with the display panel 30 as a structure independent of the display panel 30 , and the cover plate 40 is covered on the side of the touch structure 20 away from the display panel 30 . In other embodiments, the touch structure 20 can be embedded in the display panel 30 , and the embodiment of the present invention does not limit the structure of the touch structure 20 and the display panel 30 . The touch structure 20 is used to identify the user's touch operation on the touch structure 20, the display panel 30 is used to display images according to the touch operation, the surface 41 of the cover plate 40 is used to display the image displayed on the display panel 30, It is also used to receive the user's touch operation. In this embodiment, the user's touch operat...

Embodiment 2

[0066] Please refer to 10, the difference between the touch control structure 50 provided in this embodiment and the first embodiment is that the first switch element 25 is replaced by the second switch element 55 in this embodiment.

[0067] read on Figure 10 In the touch structure 50 provided in this embodiment, in each touch unit 52, a second switch element 55 is electrically connected between every two adjacent touch electrodes 521. In this embodiment, the second switch element 55 It is a thin film transistor and is arranged on the substrate 51 . The gate g of the second switch element 55 is electrically connected to the driver 53 , and the source s and the drain d are respectively electrically connected to a touch electrode 521 . According to the operating characteristics of the thin film transistor, when the voltage applied to the gate g of the second switching element 55 reaches the threshold voltage of the second switching element 55, the source s and the drain d of ...

Abstract

The invention provides a touch structure. The touch structure comprises a substrate; at least one touch unit, arranged on the substrate, and each touch unit comprising at least two touch electrodes; adriver, arranged on the substrate, electrically connected with the touch electrodes and used for outputting touch driving signals to drive the touch electrodes and recognizing touch operation according to the touch sensing signals on the touch electrodes; and a plurality of connecting lines, wherein each connecting line is electrically connected with one touch electrode and the driver. The driveris further used for controlling the touch structure to work in a first touch mode and a second touch mode in a time-sharing mode according to the touch sensing signals, and when the touch structure works in the first touch mode, the touch electrodes are connected in parallel to independently receive touch driving signals output by the driver. When the touch control structure works in a second touch control mode, the touch control electrodes in each touch control unit are connected in series to receive touch control driving signals output by the driver together. The invention further providesa touch display device and a touch method.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to a touch structure, a touch method applied to the touch structure, and a touch display device including the touch structure. Background technique [0002] As a convenient device for human-computer interaction, the touch panel has been widely used in various smart devices, and the common touch modes include coordinate touch and near-field gesture sensing. [0003] The touch panel usually includes a plurality of touch electrodes. When a finger touches the touch panel, the touch coordinates of the finger at the current moment can be obtained through the electrical signals on the plurality of touch electrodes, which is coordinate touch; Near-field gesture sensing does not require fingers to directly touch the touch panel, and the touch panel can sense the gesture of a finger at a certain distance from it. In the above two touch modes, in the coordinate touch mode, the smaller ...
