[0002] In recent years, the application of touch control technology on display devices of various sizes is more and more extensive. As a new type of panel for human-computer interaction input, the display panel is simpler, more direct and more convenient in input compared with the traditional display, keyboard and mouse input.

[0003] In the prior art, the display panel needs to be provided with an opening to set an optical element such as a camera, and the opening is set close to the edge of the display panel to avoid affecting the user experience, but the space between the opening and the edge of the display panel is limited, which cannot meet the touch control requirement and affects normal touch control.

[0004] Therefore, there is an urgent need for a new display panel and display device. SUMMARY

[0005] The display panel and display device provided by the embodiments of the present application solve the problem of too small capacitance signal quantity caused by the small area of the first display area and the limited arrangement area of the first electrode by separately arranging the first electrode in the first display area, i.e. the first electrode adopts a self-capacitance touch control form, and arranging the second electrode and the third electrode in the second display area, thereby ensuring normal touch control of the display panel in the first display area.

[0006] In a first aspect, the embodiments of the present application provide a display panel, the display panel having a first non-display area and a display area arranged at least partially around the first non-display area, the display area including a first display area and a second display area arranged adjacently, a region between the first non-display area and an edge of the display panel closest to the first non-display area being the first display area, the display panel comprising: a substrate; a touch control layer arranged on one side of the substrate, the touch control layer including a first electrode, a second electrode and a third electrode, the first electrode being arranged in the first display area, and each of the first electrodes being insulated from each other; the second electrode and the third electrode being arranged in the second display area, the second electrode being arranged along a first direction, the third electrode being arranged along a second direction, adjacent second electrodes being electrically connected along the first direction, adjacent third electrodes being electrically connected along the second direction, and the first direction and the second direction intersecting.

[0018] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In the detailed description below, many specific details are proposed in order to provide a comprehensive understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.

[0019] 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 variations 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, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element.

[0020] In related technologies, an opening needs to be opened on the display panel to set up optical elements such as a camera. Due to the limitations of the existing display panel structure, the space between the opening and the display panel is relatively small. If the existing mutual capacitance touch structure is adopted, the capacitance value of the touch electrode between the opening and the display panel will not meet the requirements, affecting the accuracy of the display panel touch.

[0021] In order to solve the above problems, the embodiment of the present invention arranges the first electrode in the touch layer separately in the first display area, that is, the first electrode adopts the self-capacitive touch form, and the second electrode and the third electrode are arranged in the second display area, so as to compensate for the problem of too small capacitance signal amount caused by the small area of ​​the first display area and the limited layout area of ​​the first electrode, thereby ensuring normal touch of the display panel in the first display area.

[0022] In order to better understand the present invention, Figures 1 to 8 A display panel and a display device according to embodiments of the present invention are described in detail.

[0023] Please also refer to Figures 1 to 2 , Figure 1 is a schematic structural diagram of a display panel provided according to an embodiment of the present invention; Figure 2 An embodiment provides Figure 1The local enlarged view at the middle B; an embodiment of the application provides a display panel, the display panel has a first non-display area NA1 and a display area AA arranged at least partially around the first non-display area NA1, the display area AA includes a first display area AA1 and a second display area AA2 arranged adjacently, the area between the first non-display area NA1 and the edge of the display panel closest to the first non-display area NA1 is the first display area AA1, the display panel comprises: a substrate 1; a touch layer 2 arranged on one side of the substrate 1, the touch layer 2 includes a first electrode 21, a second electrode 22 and a third electrode 23, the first electrode 21 is arranged in the first display area AA1, and each first electrode 21 is insulated from each other; the second electrode 22 and the third electrode 23 are arranged in the second display area AA2, the second electrode 22 is arranged along a first direction X, the third electrode 23 is arranged along a second direction Y, along the first direction X, adjacent second electrodes 22 are electrically connected, along the second direction Y, adjacent third electrodes 23 are electrically connected, and the first direction X and the second direction Y intersect.

[0024] The display panel provided by the embodiment of the application comprises a substrate 1 and a touch layer 2, the first electrode 21 in the touch layer 2 is arranged in the first display area AA1 alone, that is, the first electrode 21 adopts a self-capacitance touch form, and the second electrode 22 and the third electrode 23 are arranged in the second display area AA2, and the second electrode 22 and the third electrode 23 are arranged along the first direction X and the second direction Y respectively to form a mutual-capacitance touch structure. The inventor has found that the amount of the capacitance signal generated by the self-capacitance touch structure of the same area is much larger than the amount of the capacitance signal generated by the mutual-capacitance touch structure, that is, the capacitance value generated by the first electrode 21 of the same area when touching is larger than the capacitance value generated by the second electrode 22 or the third electrode 23 when touching, so as to make up for the problem that the amount of the capacitance signal is too small due to the small area of the first display area AA1 and the limited arrangement area of the first electrode 21, and ensure the normal touch of the display panel in the first display area AA1.

[0025] In order to avoid affecting the user experience, the first non-display area NA1 is usually arranged close to the edge of the display panel, so that the size of the area between the first non-display area NA1 and the edge of the display panel closest to the first non-display area NA1 is small, that is, the size of the first display area AA1 is small, and a complete second electrode 22 or third electrode 23 cannot be placed, only the first electrode 21 adopting a self-capacitance touch form can be placed alone, so as to ensure that even if the first electrode 21 with a small size is used, the amount of the capacitance signal generated by the first electrode 21 when touching can meet the demand.

[0026] Specifically, since the first electrode 21 adopts the self-capacitive touch form to measure the capacitance to ground, the capacitance caused by a finger touch is generally around 0.3pF, while the capacitance generated between the mutual capacitance second electrode 22 and the third electrode 23 is around 0.07pF, which is a large difference. Therefore, the capacitance difference caused by different size and area can be compensated.

[0027] In this embodiment, the second electrode 22 and the third electrode 23 also need to be insulated from each other to avoid interference between the signals transmitted therebetween.

[0028] The substrate 1 can be a hard substrate 1, such as a glass substrate; or a flexible substrate, and its material can be polyimide, polystyrene, polyethylene terephthalate, polyparaxylene, polyethersulfone or polyethylene naphthalate. The substrate 1 is mainly used to support the device arranged thereon.

[0029] See also Figure 2 In some optional embodiments, the display panel further includes a first signal line 3, a second signal line 4, and a third signal line 5; at least one first signal line 3 is connected to the first electrode 21; along the first direction X, the second electrodes 22 located in the same row are connected to the same second signal line 4, and along the second direction Y, the second electrodes 22 located in the same column are connected to the same third signal line 5.

[0030] It is understandable that the first electrode 21 can receive and feedback the touch signal through the first signal line 3 , and one of the second electrode 22 and the third electrode 23 is a touch driving electrode, and the other is a touch sensing electrode.

[0031] Optionally, the display panel also includes a chip IC. When the second electrode 22 is a touch drive electrode and the third electrode 23 is a touch sensing electrode, the chip IC sends a touch drive signal to the second electrode 22 through the second signal line 4, and transmits the touch sensing signal generated by the third electrode 23 that forms a mutual capacitance electrode pair with the second electrode 22 back to the chip IC through the third signal line 5. At this time, the touch position is determined by detecting the capacitance change between the second electrode 22 and the third electrode 23.

[0032] In addition to being used for touch functions, the first electrode 21 can also be used for other functions, such as distance detection. Specifically, different functions can be achieved by adjusting the chip IC and the signal transmitted by the first signal line 3. For example, the first signal line 3 includes a touch signal line, and the touch detection of the first electrode 21 is achieved through the touch signal line. Alternatively, the first signal line 3 includes a distance sensing signal line. Specifically, the first electrode 21 can be controlled by being separately connected to the GPIO port (general input and output port) related to the chip IC through the distance sensing signal line. The GPIO port can receive and send signals. When the sensing object is a certain distance away from the first electrode 21 and the signal amount generated reaches the touch threshold, the chip IC will report an interrupt to the host. Upon receiving the interrupt signal, the host will control the display panel to adjust the corresponding brightness, etc.

[0033] See also Figure 3 , Figure 3 is a schematic diagram of the structure of a display panel provided according to another embodiment of the present invention. Optionally, the display panel further includes a second non-display area NA2 surrounding the display area AA. A chip IC is provided in the second non-display area NA2, and the first signal line 3 extends to the second non-display area NA2 to be electrically connected to the chip IC. Because the first display area AA1 is located at the edge of the display panel, the first signal line 3 connected to the first electrode 21 located in the first display area AA1 can be directly extended to the second non-display area NA2 to be electrically connected to the chip IC. Of course, the second electrode 22 and the third electrode 23 can also be electrically connected to the chip IC via the second signal line 4 and the third signal line 5, respectively.

[0034] Optionally, the first electrode 21 , the second electrode 22 and the third electrode 23 are electrically connected to the same chip IC to reduce production costs.

[0035] See also Figure 4 , Figure 4 It is a locally enlarged view of the second electrode 22 provided according to an embodiment of the present invention; in some optional embodiments, along the first direction X, the second electrode 22 includes at least two first sub-electrodes 221, and each first sub-electrode 221 is arranged adjacent to the first non-display area NA1; two adjacent first sub-electrodes 221 are connected by a first connecting line 6, and the first connecting line 6 extends at least partially along the edge of the first non-display area NA1, and the extension trajectory of the first connecting line 6 is parallel to the outer edge contour line of the adjacent first non-display area NA1.

[0036] In this embodiment, when the first sub-electrodes 221 are disposed on either side of the first non-display area NA1 along the first direction X, the two first sub-electrodes 221 separated by the first non-display area NA1 can be connected via a first connecting line 6, with the extension path of the first connecting line 6 being parallel to the outer edge contour lines of the adjacent first non-display area NA1, thereby improving space utilization and facilitating wiring. For example, when the outer edge contour line of the first non-display area NA1 is a curve, the extension path of the first connecting line 6 corresponding to that portion of the outer edge contour line can adopt a curve with the same curvature. However, when the outer edge contour line of the first non-display area NA1 is a straight line, the extension path of the first connecting line 6 corresponding to that portion of the outer edge contour line can adopt a curve parallel to the outer edge contour line.

[0037] It should be noted that each first sub-electrode 221 is disposed adjacent to the first non-display area NA1. Adjacent arrangement can be understood as meaning that the minimum distance between the first sub-electrode 221 and the first non-display area NA1 is less than or equal to a predetermined distance. It is understood that the minimum distance between the first sub-electrode 221 and the first non-display area NA1 should not be too large, as a large distance would result in a large area without touch functionality, affecting the user experience. The minimum distance between the first sub-electrode 221 and the first non-display area NA1 should also not be too small, as this is limited by the manufacturing precision of the first sub-electrode 221. A small distance could cause interference between the first sub-electrode 221 and components within the first non-display area NA1. For example, the predetermined distance may range from 0.01 mm to 0.02 mm to meet the above requirements.

[0038] See also Figure 4 In some optional embodiments, the first sub-electrode 221 has a first side B1 facing the first non-display area NA1, and an extension track of the first side B1 is parallel to an outer edge contour line of the first non-display area NA1.

[0039] It will be appreciated that, similar to the arrangement of the extension trajectory of the first connecting line 6, in this embodiment, the extension trajectory of the first side B1 is parallel to the outer edge contour of the corresponding first non-display area NA1, also to improve the space utilization of the display panel. For example, when the outer edge contour of a portion of the first non-display area NA1 is semicircular, the extension trajectory of the first side B1 is also semicircular. However, since the first side B1 is located outside the first non-display area NA1 and there is a certain distance between the first sub-electrode 221 and the first non-display area NA1, the radius corresponding to the semicircular extension trajectory of the first side B1 is generally greater than the radius corresponding to the outer edge contour of the corresponding semicircular first non-display area NA1.

[0040] like Figure 5 As shown, Figure 5is a partial enlarged view of the first electrode 21 according to an embodiment of the present application; since the first electrode 21 is also arranged adjacent to the first non-display area NA1, the extending track of the first electrode 21 towards the edge of the first non-display area NA1 can also be parallel to the outer edge contour line of the opposite first non-display area NA1.

[0041] It should be noted that the first non-display area NA1 is the area for opening the hole to arrange the optical element such as the camera, and the specific shape and size can be selected according to actual needs, for example, the first non-display area NA1 is at least one of a rounded rectangle, a polygon, a circle and an ellipse. As shown in Figure 1 or Figure 6 , Figure 6 is a structural schematic view of the display panel according to another embodiment of the present application.

[0042] In some optional embodiments, the first electrode 21, the second electrode 22 and the third electrode 23 are arranged in the same layer. Please refer to Figure 7 , Figure 7 is a cross-sectional view of the C-C in Figure 1 Due to the position limitation, Figure 7 only the first electrode 21 and the third electrode 23 arranged in the same layer are shown in

[0043] It can be understood that the first electrode 21, the second electrode 22 and the third electrode 23 can be located in the same film layer in order to accurately realize the touch function, and the first electrode 21, the second electrode 22 and the third electrode 23 can be formed by the same process in order to reduce the production cost and facilitate the preparation. Optionally, the materials of the first electrode 21, the second electrode 22 and the third electrode 23 are the same.

[0044] For example, the first electrode 21, the second electrode 22 and the third electrode 23 can be made of ITO (Indium Tin Oxide) material at the same time, since the light transmittance of the ITO material is relatively high, which can meet the requirements of the display panel for light in or light out. Of course, the first electrode 21, the second electrode 22 and the third electrode 23 can also be made of other materials, for example, metal materials with good conductivity, such as gold, silver, aluminum, etc., and the first electrode 21, the second electrode 22 and the third electrode 23 can specifically adopt a metal grid structure to meet the light transmittance requirements.

[0045] Considering that the second electrodes 22 are electrically connected between adjacent second electrodes 22 along the first direction X, and the third electrodes 23 are electrically connected between adjacent third electrodes 23 along the second direction Y, in order to avoid the contact between the second electrodes 22 and the third electrodes 23 when the second electrodes 22 and the third electrodes 23 are located in the same layer, please refer to Figure 8 , Figure 8 is a cross-sectional view of the C-C in Figure 1Optionally, the touch layer 2 further includes a bridge layer 24 , which is disposed in a separate layer from the first electrode 21 . Adjacent second electrodes 22 are electrically connected along the first direction X via the bridge layer 24 , or adjacent third electrodes 23 are electrically connected along the second direction Y via the bridge layer 24 .

[0046] It is understood that the bridge layer 24 can also be made of ITO or metal, and the bridge layer 24 can be made of the same material as the first electrode 21, the second electrode 22, and the third electrode 23 to reduce production costs. In this embodiment, an insulating layer is provided between the third electrode 23 and the bridge layer 24. The third electrode 23 and the bridge layer 24 can be connected through vias provided in the insulating layer. The provision of the bridge layer 24 prevents interference between the third electrode 23 and the second electrode 22.

[0047] In some optional embodiments, the orthographic projection area of ​​a single second electrode 22 or a single third electrode 23 on the substrate 1 is greater than or equal to twice the orthographic projection area of ​​a single first electrode 21 on the substrate 1 .

[0048] It can be understood that since the second electrode 22 and the third electrode 23 are arranged in the second display area AA2, the space available for arrangement is more abundant than that in the first display area AA1, and the second electrode 22 and the third electrode 23 require a larger area to generate a sufficiently large capacitance signal during touch. Therefore, this embodiment requires that the positive projection area of ​​a single second electrode 22 or a single third electrode 23 on the substrate 1 be greater than or equal to the positive projection area of ​​a single first electrode 21 on the substrate 1, and according to the area of ​​the first display area AA1 and the area of ​​the first electrode 21, the positive projection area of ​​a single second electrode 22 or a single third electrode 23 on the substrate 1 can be greater than or equal to twice the positive projection area of ​​a single first electrode 21 on the substrate 1, thereby reducing the touch difference between the first electrode 21 and the second electrode 22, the third electrode 23, and improving the touch uniformity of the display panel.

[0049] like Figure 1 As shown, in some optional embodiments, the display panel has a relative first edge Y1, a second edge Y2, and relative third and fourth edges Y3 and Y4; the first non-display area NA1 is located between the first edge Y1 and the second edge Y2, and the area between the first non-display area NA1 and the third edge Y3 is the first display area AA1.

[0050] It should be noted that the first non-display area NA1 is located between the first edge Y1 and the second edge Y2. This can be understood as the first non-display area NA1 being centered relative to the first edge Y1 and the second edge Y2. The area between the first non-display area NA1 and the third edge Y3 is the first display area AA1, meaning that the first non-display area NA1 is closer to the third edge Y3 than to the fourth edge Y4. Optionally, the first edge Y1 and the second edge Y2 are the left and right edges of the display panel along the first direction X, and the third edge Y3 and the fourth edge Y4 are the upper and lower edges of the display panel along the second direction Y. The first non-display area NA1 is located in the upper half of the display panel to facilitate the optical elements located in the first non-display area NA1 to perform functions such as video recording and photography.

[0051] Of course, the first non-display area NA1 may also be located at other positions of the display panel, such as Figure 6 As shown, the first non-display area NA1 may also be disposed at a corner of the display panel, without any special limitation.

[0052] like Figure 2 As shown, in some optional embodiments, along the second direction Y, the minimum distance d from the first non-display area NA1 to the third edge Y3 ranges from 2 mm to 3 mm.

[0053] It should be noted that the minimum size of the second electrode 22 and the third electrode 23 forming the mutual capacitance touch structure is usually 4mm to 6mm, which is 2 times to 3 times the minimum distance d from the first non-display area NA1 to the third edge Y3. Therefore, there is not enough space between the first non-display area NA1 and the third edge Y3 to set the second electrode 22 and the third electrode 23 of the mutual capacitance touch structure. It is only possible to achieve touch in the area between the first non-display area NA1 and the third edge Y3, that is, the first display area AA1, by setting the first electrode 21 in the form of self-capacitance.

[0054] The embodiment of the present invention further provides a display device, comprising: the display panel in any of the above embodiments. Therefore, the display device provided by the embodiment of the present invention has the technical effects of the technical solutions in any of the above embodiments, and the explanations of the structures and terms that are the same or corresponding to the above embodiments are not repeated here.

[0055] The above is only a specific embodiment of the present invention. Those skilled in the art can clearly understand that for the convenience and simplicity of description, the specific working processes of the systems, modules and units described above can refer to the process in the aforementioned method embodiment, and will not be repeated here.
