[0047] It should be noted that, in the absence of conflict, different features in the embodiments of the present application may be combined with each other.

[0048] See also Figure 1 The display panel 1 in the related art includes a display area AA and a non-display area AB, see Figure 2The non-display area AB includes an array substrate 2 and a plurality of touch lines 31 located on one side of the array substrate 2; wherein the array substrate 2 includes a plurality of display lines 21. Signal interference may exist between the touch lines 31 and the display lines 21, which may easily lead to display ripples or large touch noise, thereby affecting the touch sensitivity of the display panel 1.

[0049] In view of this, the present embodiment provides a solution that can reduce the signal interference between the touch wiring 31 and the display wiring 21 . The solution provided by the present embodiment is described in detail below.

[0050] See also Figure 3 This embodiment provides a display panel 1, which includes a display area AA and a non-display area AB; the display panel 1 includes an array substrate 2, a pixel defining layer 4, an isolation layer 5 and a touch layer 3.

[0051] The array substrate 2 includes display wiring 21, and the display wiring 21 is at least partially located in the non-display area. The display wiring 21 can also be located in the non-display area, for example, the display wiring 21 extends from the non-display area to the display area.

[0052] The isolation layer 5 is located on one side of the array substrate 2 ; the isolation layer 5 includes an isolation structure 51 and a shielding layer 52 arranged on the same layer, the isolation structure 51 is located in the display area AA, and the shielding layer 52 is located in the non-display area AB.

[0053] Optionally, see Figure 4 The display panel 1 also includes a pixel defining layer 4 and a first electrode layer. The pixel defining layer 4 is located on one side of the array substrate 2. The pixel defining layer 4 includes a pixel opening 41. The isolation structure encloses a plurality of opening structures that are spaced apart. The isolation structure includes a conductive material. The orthographic projection of the pixel opening 41 on the array substrate 2 is located within the orthographic projection of the opening structure on the array substrate 2. The orthographic projection of the isolation structure 51 on the array substrate 2 is located between the orthographic projections of two adjacent pixel openings 41 on the array substrate 2.

[0054] The first electrode layer includes a first electrode 6 exposed through the pixel opening 41; the display panel 1 also includes a light-emitting layer 7 and a second electrode layer 8 which are sequentially stacked in the pixel opening 41, the light-emitting layer 7 includes a plurality of light-emitting structures respectively arranged in the plurality of opening structures, at least one of the opening structures is provided with a light-emitting structure, and the light-emitting structure is located on the side of the first electrode 6 away from the array substrate 2. The second electrode layer 8 includes a plurality of second electrodes respectively arranged in the opening structures and electrically connected to the conductive material of the isolation structure, that is, at least part of the second electrode layer 8 extends from the pixel opening 41 to the side of the pixel defining layer 4 away from the array substrate 2 and is in electrical contact with the isolation structure 51; wherein the first electrode 6 includes an anode; and the second electrode layer 8 includes a cathode layer.

[0055] The shielding layer 52 is provided at the same time as the isolation structure 51 . The isolation structure 51 is located between two adjacent pixel openings 41 . At least part of the first electrode 6 is located in the pixel opening 41 , that is, the pixel opening 41 exposes at least part of the first electrode 6 .

[0056] The orthographic projection of the isolation structure 51 on the array substrate 2 surrounds the orthographic projection of the pixel opening 41 on the array substrate 2. When forming the light-emitting layer 7 and the second electrode layer 8, the isolation structure 51 can disconnect the light-emitting layer 7 and the second electrode layer 8 of the adjacent light-emitting device, and make at least part of the second electrode layer 8 extend from the pixel opening 41 to the side of the pixel defining layer 4 away from the array substrate 2 to be in electrical contact with the isolation structure 51. The isolation structure 51 can connect the adjacent second electrode layer 8 or connect the second electrode layer 8 to other circuits. In this way, the patterning design of the light-emitting layer 7 and the second electrode layer 8 can be realized without using a precision mask, thereby reducing the manufacturing difficulty of the display panel 1.

[0057] A first electrode 6, a light-emitting layer 7 and a second electrode layer 8 constitute a light-emitting device. The array substrate 2 applies voltage to the first electrode 6 and the second electrode layer 8 to drive the light-emitting device to emit light. A packaging layer 9 is then provided to independently package the plurality of light-emitting devices, so that the light-emitting devices are independent of each other, thereby improving the reliability of the packaging and optimizing the optical performance of the display panel 1.

[0058] The touch layer 3 is located on the side of the isolation layer 5 away from the array substrate 2; the touch layer 3 includes a touch electrode 32 and a touch wiring 31, the touch electrode 32 is located in the display area AA, and the touch wiring 31 extends from the non-display area AB to be electrically connected to the touch electrode 32; in the thickness direction of the array substrate 2, the shielding layer 52 is at least partially located between the touch wiring 31 and the display wiring 21.

[0059] While setting the isolation structure 51 in the display area AA, a shielding layer 52 is set in the non-display area AB. The shielding layer 52 is located between the touch wiring 31 and the display wiring 21. The shielding layer 52 can increase the distance between the touch wiring 31 and the display wiring 21, thereby reducing the signal interference between the touch wiring 31 and the display wiring 21, and further improving the touch sensitivity of the display panel 1.

[0060] Based on the above design, in this embodiment, while providing the isolation structure 51 located in the display area AA, a shielding layer 52 is provided in the non-display area AB at the same layer as the isolation structure 51. The shielding layer 52 can increase the distance between the touch wiring 31 and the display wiring 21. In this way, while realizing higher-end applications of new technologies without increasing the process difficulty, the shielding effect between the touch wiring 31 and the display wiring 21 can be improved, thereby improving the touch sensitivity of the display panel 1.

[0061] In one possible implementation, see again Figure 3 , the isolation structure 51 and the shielding layer 52 both include a first isolation portion 512 and a second isolation portion 513 which are sequentially stacked in a direction away from the array substrate 2, and the orthographic projection of the first isolation portion 512 on the array substrate 2 is located within the orthographic projection of the second isolation portion 513 on the array substrate 2. Since the second isolation portion 513 is located on the side of the first isolation portion 512 away from the array substrate 2, and the lateral width of the second isolation portion 513 is greater than the lateral width of the first isolation portion 512, the second isolation portion 513 disconnects the light-emitting layer 7 and the second electrode layer 8 at the isolation structure 51. In the display area AA, the first isolation portion 512 and the second isolation portion 513 form an isolation structure 51, which can make each pixel independent.

[0062] Preferably, the first isolation portion 512 includes a conductive material, and the second electrode is electrically connected to the first isolation portion 512 .

[0063] The isolation structure 51 can allow at least a portion of the second electrode layer 8 to extend from the pixel opening 41 to the side of the pixel defining layer 4 away from the array substrate 2 and to be in electrical contact with the first isolation portion 512 in the isolation structure 51. The first isolation portion 512 of the isolation structure 51 can connect the adjacent second electrode layer 8 or connect the second electrode layer 8 to other circuits.

[0064] Alternatively, see again Figure 4 , the isolation structure 51 also includes a third isolation portion 511 located on the side of the first isolation portion 512 facing the array substrate 2, the third isolation portion 511 includes a conductive material, and the second electrode is electrically connected to the third isolation portion 511. The material of the first isolation portion 512 may include aluminum metal, the material of the second isolation portion 513 may include a conductive material, an inorganic material or an organic material, and the material of the third isolation portion 511 may include molybdenum metal. At least part of the second electrode layer 8 extends from the pixel opening 41 to the side of the pixel defining layer 4 away from the array substrate 2 and is in electrical contact with the third isolation portion 511 in the isolation structure 51. The third isolation portion 511 of the isolation structure 51 can connect the adjacent second electrode layer 8 or connect the second electrode layer 8 to other circuits.

[0065] In one possible implementation, see Figure 4-Figure 5 The non-display area AB at least partially surrounds the display area AA, the number of the shielding layer 52 is one, and one shielding layer 52 at least partially surrounds the display area AA; in the thickness direction of the array substrate 2, the shielding layer 52 is located between the touch wiring 31 and the display wiring 21.

[0066] At least part of the display wiring 21 can also be located at the frame position of the display panel 1 and surround the display area AA, so the shielding layer 52 is arranged along the direction of the display wiring 21, and the shielding layer 52 is arranged as a whole layer at the frame position of the display panel 1. In this way, the shielding layer 52 can better isolate the display wiring 21 and the touch wiring 31, thereby improving the shielding effect of the shielding layer 52 on the display wiring 21 and the touch wiring 31.

[0067] In one possible implementation, see Figure 6-Figure 7 The non-display area AB at least partially surrounds the display area AA, there are multiple shielding layers 52, and the multiple shielding layers 52 at least partially surround the display area AA. The multiple shielding layers 52 are arranged along the direction from the non-display area AB to the display area AA; in the thickness direction of the array substrate 2, the shielding layer 52 is located between the touch wiring 31 and the display wiring 21.

[0068] The shielding layer 52 is arranged along the direction of the display wiring 21, and the shielding layer 52 is arranged as a plurality of annular structures surrounding the display area AA at the frame position of the display panel 1, and each annular structure separates one or more display wirings 21 and the touch wiring 31. In this way, the material used for the shielding layer 52 can be reduced without affecting the shielding effect of the shielding layer 52 on the display wiring 21 and the touch wiring 31.

[0069] In a possible implementation, the display wiring 21 includes at least one of a scanning control signal wiring, a light emitting control signal wiring, or a data signal wiring.

[0070] The scanning control signal line provides a scanning signal for the pixel, the light-emitting control signal line provides a light-emitting signal for the pixel, and the data signal line provides a data voltage signal for the pixel. The shielding layer 52 is located between the scanning control signal line or the light-emitting control signal line or the data signal line and the touch line 31. Therefore, the shielding layer 52 can shield at least one of the scanning control signal line or the light-emitting control signal line or the data signal line and the touch line 31.

[0071] In one possible implementation, see again Figure 4 The second electrode layer 8 extends to the non-display area AB, and the second electrode layer 8 is located between the shielding layer 52 and the touch wiring 31 .

[0072] When setting the second electrode layer 8 in the display area AA, the second electrode layer 8 is also formed in the non-display area AB. The second electrode layer 8 is located between the shielding layer 52 and the touch wiring 31. Therefore, the second electrode layer 8 can also shield the touch wiring 31 and the display wiring 21, thereby improving the shielding effect of the touch wiring 31 and the display wiring 21, and further improving the touch sensitivity of the display panel 1.

[0073] In summary, the present application sets a shielding layer 52 on the same layer as the isolation structure 51 in the non-display area AB while setting the isolation structure 51 in the display area AA. The shielding layer 52 can greatly increase the distance between the touch wiring 31 and the display wiring 21. In this way, the shielding effect between the touch wiring 31 and the display wiring 21 can be improved without increasing the process difficulty, reducing material waste, and realizing higher-end applications of new technologies, thereby improving the touch sensitivity of the display panel 1. At the same time, setting the shielding layer 52 in the frame can make the frame smoother, so that it is less likely to break the wiring of the frame.

[0074] In one possible implementation, see Figure 8 The present application also provides a method for preparing a display panel 1, wherein the display panel 1 includes a display area AA and a non-display area AB; the method includes:

[0075] S10: providing an array substrate 2; the array substrate 2 comprises display wiring 21, and the display wiring 21 is at least partially located in the display area AA.

The backplane may include multiple metal traces and / or multiple driving units for transmitting signals or electrical energy. The metal traces and / or the driving units are electrically connected to the bonding electrodes, and the bonding electrodes are electrically connected to the light-emitting devices. The metal traces and the driving units can be used to drive the light-emitting devices, wherein the metal traces include display traces 21.

[0077] S11: forming an isolation layer 5 on one side of the array substrate 2; the isolation layer 5 comprises an isolation structure 51 and a shielding layer 52 arranged on the same layer, the isolation structure 51 is located in the display area AA, and the shielding layer 52 is located in the non-display area AB.

[0078] S12: A touch layer 3 is formed on a side of the isolation layer 5 away from the array substrate 2; the touch layer 3 includes a touch electrode 32 and a touch wiring 31, the touch electrode 32 is located in the display area AA, and the touch wiring 31 extends from the non-display area AB to be electrically connected to the touch electrode 32; in the thickness direction of the array substrate 2, the shielding layer 52 is at least partially located between the touch wiring 31 and the display wiring 21.

[0079] See also Fig. 9 While setting the isolation structure 51 in the display area AA, a shielding layer 52 is set in the non-display area AB. The shielding layer 52 is located between the touch wiring 31 and the display wiring 21. The shielding layer 52 can greatly increase the distance between the touch wiring 31 and the display wiring 21, thereby reducing the signal interference between the touch wiring 31 and the display wiring 21, and further improving the touch sensitivity of the display panel 1.

[0080] In a possible embodiment, before the step of forming the touch layer 3 on the side of the isolation layer 5 away from the array substrate 2, it also includes: sequentially forming a stacked first electrode 6, a light-emitting layer 7 and a second electrode layer 8 in a plurality of opening structures enclosed by the isolation structure 51 and spaced apart; the light-emitting layer 7 includes a plurality of light-emitting structures respectively arranged in the plurality of opening structures, at least one opening structure is provided with a light-emitting structure, and the light-emitting structure is located on the side of the first electrode 6 away from the array substrate 2; the second electrode layer 8 includes a plurality of second electrodes respectively arranged in the opening structures and electrically connected to the conductive material of the isolation structure 51.

The number of pixel openings 41 can be multiple, and one pixel opening 41 corresponds to one light-emitting device. When forming the light-emitting layer 7 and the second electrode layer 8, the isolation structure 51 can disconnect the light-emitting layer 7 and the second electrode layer 8 of the adjacent light-emitting device, and make at least part of the second electrode layer 8 extend from the pixel opening 41 to the side of the pixel defining layer 4 away from the array substrate 2 to be in electrical contact with the isolation structure 51, and the isolation structure 51 can connect the adjacent second electrode layer 8 or connect the second electrode layer 8 to other circuits. In this way, the patterning design of the light-emitting layer 7 and the second electrode layer 8 can be realized without using a precision mask, thereby reducing the manufacturing difficulty of the display panel 1.

[0082] A packaging layer 9 may be formed on the side of the second electrode layer 8 away from the array substrate 2 . The packaging layer 9 independently packages the sub-pixels formed by the first electrode 6 , the light-emitting layer 7 and the second electrode layer 8 , thereby improving the packaging reliability of the display panel 1 .
