Embodiment 1

[0048] refer to figure 2 , showing a schematic structural view of a touch display panel according to an embodiment of the present invention, image 3 show figure 2 The sectional view of the shown touch display panel along section A-A', Figure 4 show figure 2 The shown cross-sectional view of the touch display panel along section B-B'.

[0049] An embodiment of the present invention provides a touch display panel, including: a substrate 21, an electrode connection layer 22 formed on the substrate 21; a first insulating layer 23, the first insulating layer 23 covering the electrode connection layer 22, formed on the The electrode layer 24 on the first insulating layer 23 .

[0050] Wherein, the electrode layer 24 includes a plurality of first electrodes 241 and a plurality of second electrodes 242, such as figure 2 As shown, both the first electrode 241 and the second electrode 242 are in a ring-shaped closed structure, and the second electrode 242 surrounds the first ...

Embodiment 2

[0070] refer to Figure 6 , which shows a flow chart of a method for manufacturing a touch display panel according to an embodiment of the present invention, which may specifically include the following steps:

[0071] Step 601, providing a substrate.

[0072] In the embodiment of the present invention, when manufacturing the touch display panel, a substrate 21 needs to be provided first.

[0073] Specifically, a light-emitting device is formed on a base; an encapsulation layer is formed, and the encapsulation layer covers the light-emitting device; and a second insulating layer is formed on the encapsulation layer.

[0074] refer to Figure 7 , shows a schematic structural view of the substrate formed in the embodiment of the present invention.

[0075] Firstly, an anode is formed on the substrate 211, then a light-emitting layer is formed on the anode by evaporation or printing, and finally a cathode is formed to realize the formation of the light-emitting device 212 on t...

Embodiment 3

[0098] An embodiment of the present invention provides a display device, including the above-mentioned touch display panel.

[0099] Of course, the display device also includes a driving chip, which is respectively connected to the first electrode 241 and the second electrode 242 in the electrode layer 24. When the first electrode 241 is the sensing electrode Rx and the second electrode 242 is the driving electrode Tx, It is used to provide a detection signal to the second electrode 242 in the electrode layer 24 and receive a signal from the first electrode 241 in the electrode layer 24 to calculate the user's touch position; or, when the first electrode 241 is a driving electrode Tx, the second electrode When the second electrode 242 is the sensing electrode Rx, it is used to provide a detection signal to the first electrode 241 in the electrode layer 24 and receive a signal from the second electrode 242 in the electrode layer 24 to calculate the user's touch position.

Abstract

The invention provides a touch display panel, a manufacturing method thereof, and a display device, and relates to the field of display technology. In the present invention, an electrode connection layer is formed on a substrate, a first insulating layer covering the electrode connection layer is formed, an electrode layer is formed on the first insulation layer, and the electrode layer includes a plurality of first electrodes and a plurality of second electrodes, the first Both the electrode and the second electrode have a ring-shaped closed structure, and the second electrode surrounds the first electrode, and two adjacent first electrodes in each column are respectively connected to the electrode connection layer through the through holes penetrating the first insulating layer, and the phase of each row is connected to the electrode connection layer. The adjacent two second electrodes are connected. By arranging a plurality of first electrodes and a plurality of second electrodes in the electrode layer, and the second electrodes surround the first electrodes, thereby reducing the area occupied by the first electrodes, so that within a unit area, the touch display panel arranged The number of driving electrodes and sensing electrodes can be greatly increased, which improves the utilization rate of the touch display panel, thereby improving the touch resolution and making the touch accuracy higher.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch display panel, a manufacturing method thereof, and a display device. Background technique [0002] With the continuous development of display technology, touch display technology has also received extensive attention. Generally, driving electrodes and sensing electrodes are made on the packaged light emitting device to form a TSP (Touch Screen Panel, touch display panel). By inputting the detection signal to the driving electrodes, when the user touches the touch display panel, the signal on the sensing electrode at the touch position will change, and the user's touch position can be determined according to the position where the signal changes. [0003] Such as figure 1 As shown, currently the driving electrodes Tx and sensing electrodes Rx in the touch display panel are set separately, and the number of driving electrodes Tx and sensing electrodes Rx set in th...
