DETAILED DESCRIPTION

[0029] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present application and are not configured to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is merely to provide a better understanding of the present application by illustrating the examples of the present application.

[0030] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, the elements defined by the phrase "comprising..." do not exclude the presence of other identical elements in the process, method, article, or device comprising the elements.

[0031] It should be understood that when describing the structure of a component, when a layer or a region is referred to as being "on" or "over" another layer or region, it may mean that it is directly on the other layer or region, or that other layers or regions are included between it and the other layer or region. Furthermore, if the component is turned over, the layer or region will be "below" or "beneath" the other layer or region.

[0032] It will be apparent to those skilled in the art that various modifications and variations can be made in this application without departing from the spirit or scope of this application. Therefore, this application is intended to cover modifications and variations of this application that fall within the scope of the corresponding claims (technical solutions claimed for protection) and their equivalents. It should be noted that the embodiments provided in the examples of this application can be combined with each other without contradiction.

[0033] In the prior art, when a self-capacitive touch structure is used in a display device, the distance between the touch electrode and the cathode is sharply reduced, resulting in a sharp increase in the touch load. When the display panel size is small (such as a mobile phone screen), the touch performance is still satisfactory. However, when the display panel size continues to increase, the touch load will approach the upper limit of the display panel IC specification, resulting in a decrease in touch performance.

[0034] In order to solve the above problems, an embodiment of the present invention increases the amount of change in the signal of the touch unit during touch control by providing at least two rows of first sub-sections extending along the first direction, second sub-sections located between the first sub-sections, and third sub-sections located between the first sub-sections and the second sub-sections, thereby meeting the touch control needs when the display panel is applied to medium and large-sized display devices and improving the performance of the display panel.

[0035] See also Figures 1 to 3, an embodiment of the present application provides a display panel, the display panel includes: a touch layer, the touch layer includes a plurality of touch units 10 arranged in an array along a first direction and a second direction, the touch unit 10 includes a first touch electrode 1 and a second touch electrode 2 that are insulated from each other, and the first direction and the second direction intersect; the first touch electrode 1 includes a first sub-portion 11 and a second sub-portion 12 extending along the first direction, at least two rows of first sub-portions 11 are arranged at intervals along the second direction, the second sub-portions 12 are arranged between two adjacent rows of first sub-portions 11, and adjacent second sub-portions 12 are arranged at intervals along the first direction; along the first direction, the touch unit 10 includes at least three first sub-portions 11 arranged at intervals, and adjacent first sub-portions 11 along the first direction are connected by a bridge portion 3; the second touch electrode 2 includes a third sub-portion 21 extending along the first direction, and the third sub-portion 21 is arranged between the first sub-portion 11 and the second sub-portion 12 along the second direction Y, and adjacent third sub-portions 21 along the second direction Y are connected by the intervals between adjacent second sub-portions 12.

[0036] A display panel provided in an embodiment of the present invention includes a touch layer, which includes touch cells 10 arranged in a repeating array along a first direction X and a second direction Y. The inventors have discovered through experimental research that by providing at least two rows of first sub-sections 11 extending along the first direction X, second sub-sections 12 located between the first sub-sections 11, and third sub-sections 21 located between the first sub-sections 11 and the second sub-sections 12, the signal change of the touch cells 10 during touch control can be increased, meeting the touch control requirements of the display panel when applied to medium- and large-sized display devices. Furthermore, along the first direction X, the touch cell 10 includes at least three first sub-sections 11 spaced apart from each other. Adjacent first sub-sections 11 along the first direction X are connected by bridges 3. At least four bridges 3 are provided in a touch cell 10. The increased number of bridges 3 allows for the use of smaller bridges 3, reducing their visibility and channel impedance, thereby improving the performance of the display panel.

[0037] Optionally, the touch layer includes a first conductive layer and a second conductive layer insulated from each other, the first touch electrode 1 and the second touch electrode 2 are located in the second conductive layer, the bridge portion 3 is located in the first conductive layer, and the bridge portion 3 is connected to the first sub-portions 11 adjacent along the first direction X through vias.

[0038] In this embodiment, the number of touch units 10 can be designed based on the actual size of the display panel, and the size of the touch units 10 can be selected accordingly. For example, the touch area size of a 12.3-inch product is 267.4mm*167.87mm, and the number of touch units 10 is 66*42, so the total size is 4.05mm*4.0mm.

[0039] It should be noted that the number of rows, width and other parameters of the first sub-section 11, the second sub-section 12 and the third sub-section 21 in the touch unit 10 need to be set according to the designed size of the touch unit 10. For example, when the size of the touch unit 10 is 4.mm*4.0mm, the touch unit 10 may include two rows of first sub-sections 11, a row of second sub-sections 12 located between the two rows of first sub-sections 11, and two rows of third sub-sections 21 located between the first sub-sections 11 and the second sub-sections 12.

[0040] Along the second direction Y, adjacent third sub-portions 21 are connected via the spaces between adjacent second sub-portions 12 , and this portion of the second touch electrodes 2 may be in an I-shaped structure.

[0041] See also Figure 2 In some optional embodiments, the first touch electrode 1 further includes a first connecting portion 13 extending along the second direction Y. In the touch unit 10 , along the second direction Y, adjacent first sub-portions 11 and second sub-portions 12 are connected via the first connecting portion 13 .

[0042] In this embodiment, along the second direction Y, adjacent first sub-sections 11 and second sub-sections 12 are connected by first connecting sections 13 to connect the first sub-sections 11 into an electrically connected whole, thereby facilitating the unified transmission of touch signals to the first sub-sections 11 .

[0043] Optionally, the touch units 10 are rectangular to facilitate regular arrangement.

[0044] Optionally, the first sub-section 11 , the second sub-section 12 , and the second sub-section 12 are all rectangular, which is convenient for preparation.

[0045] Optionally, the first connecting portion 13 is provided at an edge of the touch unit 10 extending along the second direction Y to prevent the first connecting portion 13 from affecting the arrangement of the second touch electrodes 2. The first connecting portion 13 can be provided on both sides of the touch unit 10 that are opposite to each other along the first direction X to ensure a connection between the first sub-portions 11.

[0046] See also Figure 2 In some optional embodiments, the second touch electrode 2 further includes a fourth sub-portion 22 extending along the first direction X. The fourth sub-portion 22 is provided on a side of the first sub-portion 11 away from the second sub-portion 12 and is connected to the third sub-portion 21 .

[0047] In this embodiment, the fourth sub-section 22 is arranged on the side of the first sub-section 11 away from the second sub-section 12, that is, in the touch unit 10, the fourth sub-section 22 can be arranged corresponding to the edges of the touch unit 10 on both sides along the second direction Y. By setting the fourth sub-section 22, the setting area of ​​the second touch electrode 2 can be increased, and along the second direction Y, the fourth sub-sections 22 in adjacent touch units 10 can be connected, so that along the second direction Y, the second touch electrodes 2 in adjacent touch units 10 form an electrically connected whole, which is convenient for uniformly sending touch signals to the second touch electrodes 2.

[0048] Optionally, the fourth sub-portion 22 is rectangular, and the fourth sub-portions 22 in adjacent touch units 10 are spaced apart along the first direction X, so that the second touch electrodes 2 in adjacent touch units 10 along the first direction X are insulated from each other to avoid mutual interference.

[0049] It should be noted that in this embodiment, slots may be provided between adjacent fourth sub-sections 22 in adjacent touch units 10 to form a gap, thereby isolating adjacent fourth sub-sections 22 from each other to prevent mutual interference and affect touch accuracy. The slots may be provided along the second direction.

[0050] See also Figures 4 and 5 In some optional embodiments, the bridge portion 3 includes at least two second connecting portions 31, each second connecting portion 31 being connected to adjacent first sub-portions 11 along the first direction X. In this embodiment, the extending direction of the bridge portion 3 can be selected based on the specific location of the connected first sub-portions 11. For example, the bridge portion 3 can extend along the first direction X, the second direction Y, or other directions, without particular limitation.

[0051] In this embodiment, the bridge portion 3 may include two, three or more second connection portions 31 . By adjusting the number of the second connection portions 31 , the resistance load of the second connection portions 31 can be correspondingly adjusted, thereby adjusting the touch effect.

[0052] Optionally, the second connecting portion 31 is at least partially arranged in a different layer from the first sub-portion 11, that is, the second connecting portion 31 and the first sub-portion 11 can be located in different layers, and the second connecting portion 31 can be electrically connected to the first sub-portion 11 through a via to avoid interference between the second connecting portion 31 and the second touch electrode 2, so that the fourth sub-portion 22 can be electrically connected to the third sub-portion 21 through the gap between adjacent first sub-portions 11 along the first direction X.

[0053] In some optional embodiments, the first touch electrode 1 and the second touch electrode 2 both have a metal grid structure. The metal grid structure can improve the transmittance of the display panel. The material of the metal grid structure can include at least one of metal materials such as molybdenum, titanium, aluminum, and silver.

[0054] See also Figures 6 and 7 In some optional embodiments, the display panel further includes a stacked substrate and a light-emitting layer, and the touch layer is provided on the side of the light-emitting layer facing away from the substrate; the light-emitting layer includes a light-emitting unit F, and the metal grid structure includes an opening K, and the orthographic projection of the opening K on the substrate covers the orthographic projection of the light-emitting unit F on the substrate.

[0055] It is understandable that since the first touch electrode 1 and the second touch electrode 2 are both metal grid structures, and the metal grid structure includes an opening K, the orthographic projection of the opening K on the substrate is limited to cover the orthographic projection of the light-emitting unit F on the substrate, so that the touch of the light-emitting unit F can be emitted just through the opening K, thereby improving the light emitting effect of the display panel and ensuring the display effect.

[0056] The orthographic projection of the opening K on the substrate covers the orthographic projection of the light emitting unit F on the substrate, which means that the size of the opening K can be exactly equal to the size of the light emitting unit F, or the size of the opening K can be larger than the size of the light emitting unit F to avoid obstruction.

[0057] Optionally, the orthographic projection shape of the opening K on the substrate matches the orthographic projection shape of the light-emitting unit F on the substrate to ensure the light extraction efficiency of the light-emitting unit F. For example, when the orthographic projection shape of the opening K on the substrate is rectangular, the orthographic projection of the light-emitting unit F on the substrate is also rectangular, and the arrangement of the opening K can also correspond to the arrangement of the light-emitting unit F, so that the opening K and the light-emitting unit F can be set one-to-one to improve the light extraction efficiency.

[0058] Optionally, the light-emitting unit F includes multiple light-emitting units F with different light-emitting colors, for example, it may include a red light-emitting unit F, a green light-emitting unit F and a blue light-emitting unit F, the red light-emitting unit F, the green light-emitting unit F and the blue light-emitting unit F have different sizes or shapes, and the metal grid structure can correspond to the openings K of different light-emitting units F.

[0059] See also Figure 3 In some optional embodiments, along the first direction X, adjacent first touch electrodes 1 in adjacent touch units 10 are electrically connected, and adjacent second touch electrodes 2 are insulated; and / or, along the second direction Y, adjacent first touch electrodes 1 in adjacent touch units 10 are insulated, and adjacent second touch electrodes 2 are electrically connected.

[0060] It should be noted that, along the first direction X, adjacent first touch electrodes 1 located in different touch control units 10 can be interconnected to form an electrically connected whole, facilitating unified signal control, while adjacent second touch electrodes 2 are insulated from each other to enable independent control. Similarly, along the second direction Y, adjacent second touch electrodes 2 located in different touch control units 10 can be interconnected to form an electrically connected whole, facilitating unified signal control, while adjacent first touch electrodes 1 are insulated from each other to enable independent control.

[0061] Optionally, along the first direction X and / or the second direction Y, within the touch unit 10, the first touch electrode 1 is symmetrically arranged about the center of the touch unit 10, that is, the first touch electrode 1 can be symmetrically arranged about the center of the touch unit 10 along the first direction X and the second direction Y, or can be symmetrically arranged about the center of the touch unit 10 along only one of the first direction X and the second direction Y, so as to improve the symmetry of the first touch electrode 1, facilitate preparation, and facilitate adjustment of touch performance.

[0062] Similarly, optionally, along the first direction X and / or the second direction Y, within the touch unit 10, the second touch electrodes 2 are symmetrically arranged about the center of the touch unit 10 to improve the symmetry of the second touch electrodes 2, thereby facilitating preparation and adjusting touch performance.

[0063] See also Figure 8 In some optional embodiments, the touch unit 10 further includes a virtual electrode 4, which is disposed in the first touch electrode 1 and / or the second touch electrode 2, and the virtual electrode 4 is insulated from the first touch electrode 1 and the second touch electrode 2.

[0064] In this embodiment, the capacitive load of the touch layer can be changed by providing a virtual electrode 4 that is insulated from the first touch electrode 1 and the second touch electrode 2. That is, by adjusting the size of the virtual electrode 4, the size of the capacitive load of the touch layer can be correspondingly adjusted, thereby improving the touch performance.

[0065] Optionally, the virtual electrode 4 includes a first virtual electrode portion 41 extending along the first direction X. Along the first direction X, the first virtual electrode portion 41 is arranged along the edge of the first touch electrode 1. In this embodiment, the first virtual electrode portion 41 can be used to adjust the size of the capacitive load on the one hand. On the other hand, since the first virtual electrode portion 41 is arranged along the edge of the first touch electrode 1, the first virtual electrode portion 41 can also serve to isolate the first touch electrode 1 and the second touch electrode 2. Of course, there is a gap between the first virtual electrode portion 41 and the first touch electrode 1 and the second touch electrode 2.

[0066] In some optional embodiments, within the touch unit 10, the minimum distance between adjacent first sub-sections 11 along the first direction X is greater than or equal to 0.1 mm and less than or equal to 0.4 mm. It is understandable that the size of the minimum distance between adjacent first sub-sections 11 along the first direction X will affect the impedance of the first sub-sections 11, and the minimum distance between adjacent first sub-sections 11 along the first direction X can be set according to the required impedance.

[0067] Optionally, in the touch unit 10 , the minimum distance between adjacent first sub-portions 11 along the first direction X may be equal to any one of 0.1 mm, 0.2 mm, 0.3 mm, and 0.4 mm.

[0068] And / or, within the touch sensing unit 10, along the first direction X, the minimum distance between adjacent second sub-sections 12 is greater than or equal to 0.2 mm and less than or equal to 0.5 mm. Similarly, along the first direction X, the minimum distance between adjacent second sub-sections 12 also needs to be selected based on the impedance of the second sub-sections 12. Optionally, within the touch sensing unit 10, along the first direction X, the minimum distance between adjacent second sub-sections 12 can be any one of 0.2 mm, 0.3 mm, 0.4 mm, and 0.5 mm.

[0069] See also Figure 9 The following is an optimal solution size range of the touch unit 10 provided by an embodiment, wherein:

[0070] A is the design length of the touch unit 10 along the first direction X, A1 ranges from 0.1 mm to 0.4 mm (determined by impedance), A2 is equal to A-2×A3, and A2 is maximized. A3 is equal to the width of a light-emitting unit F, that is, the position corresponding to A3 can accommodate a light-emitting unit F, and A4 ranges from 0.2 mm to 0.5 mm (determined by impedance).

[0071] B is the designed length of the touch unit 10 along the second direction Y, B1 is equal to 1 / 12×B, B2 is equal to 1 / 6×B, B3 is equal to 1 / 6×B, and B4 is equal to the width of 1 to 3 light-emitting units F.

[0072] Through research and experiments by the inventors, it was found that compared with the touch unit 10 in the prior art, the touch unit 10 using the above parameters can effectively improve the touch change amount and the low-impedance grounding state measurement value, meeting the needs of medium-sized display panels, active pens and automotive products.
