[0041] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0042] Figure 1 A schematic diagram of a partial structure of a display panel provided by the prior art. Figure 2 The schematic diagram of the partial structure of another display panel provided in the prior art exemplifies the structure of the sensor setting area of ​​the display panel. Figure 1 and Figure 2 The sensor setting area of ​​the display panel 01 includes a pixel area 021, a wiring area 022, and a blank area other than the pixel area 021 and the wiring area 022. Taking the sensor module as an example of a camera, the blank area is the camera's photographing area, and the light transmittance of the photographing area directly affects the camera's photographing effect. Figure 1 In some blank areas, support columns 011 are set. Since support columns 011 have the function of absorbing light, they will reduce the light transmittance at their locations. Therefore, there is a difference in the light transmittance of the photographing area where support columns 011 are set and the light transmittance of the photographing area where no support columns are set, which will affect the photographing effect of the image camera. Figure 2 Other film layers may also be provided in the sensor setting area. Taking the setting of a functional film layer as an example, the functional film layer may include multiple (exemplarily, two) functional film layer blocks 012. Since there is a gap between the two adjacent functional film layer blocks 012, a part of the photographing area may be completely covered by the same functional film layer block 012, while the other part of the photographing area not only has two local areas of different functional film layer blocks 012, but also has a gap area between the two functional film layer blocks 012. Therefore, since the film layer structures corresponding to different photographing areas are different, the light transmittance of different photographing areas is different, which will affect the photographing effect of the camera.

[0043] To address the above issues, an embodiment of the present invention provides a display panel, wherein the sensor setting area of ​​the display panel includes at least one photosensitive element setting area; the light transmittance of each photosensitive element setting area is the same, that is, the photosensitive element setting areas of the display panel have the same effect on light, so that the uniformity of the light information received at each position of the sensor module is better, thereby facilitating the improvement of the sensor module's photosensitivity. This is the core invention of the embodiment of the present invention, and the following is combined with Figure 3-30 The display panel and the display device provided by the embodiments of the present invention are exemplarily described.

[0044] For example, Figure 3A schematic structural diagram of a display panel provided by an embodiment of the present invention is shown in FIG. Figure 4 This is a structural diagram of a sensor setting area of ​​another display panel provided by an embodiment of the present invention. Figure 3-Figure 4 The display panel 10 includes: a sensor setting area 111, and a display area 112 surrounding the sensor setting area 111; the sensor setting area 111 includes at least one photosensitive element setting area 113; and the light transmittance of each photosensitive element setting area 113 is the same.

[0045] Among them, the display area 112 is used to display images; the photosensitive element setting area 113 in the sensor setting area 113 is used to place the photosensitive element. By setting the light transmittance of each photosensitive element setting area 113 to be the same, the light transmittance of the photosensitive element setting area 113 in the display panel can be made more uniform in the light incident path of each photosensitive element. As a result, the uniformity of the light information received by the photosensitive elements at the corresponding positions is better, which is beneficial to improving the photosensitivity effect of the sensor module.

[0046] Exemplarily, the sensor module is a camera, and the photosensitive element setting area 113 corresponds to the camera's photographing area. By setting the light transmittance of each photographing area to be the same, the uniformity of the light information received at each position of the camera can be better, which is beneficial to improving the camera's photographing effect.

[0047] First of all, it should be noted that Figure 3 The sensor setting area 111 is circular in shape and is located within the display area 112. That is, the display area 112 surrounds the edges of the sensor setting area 111. However, this does not limit the display panel 10 provided in this embodiment of the present invention. In other embodiments, the sensor setting area 111 may be located on one side edge of the display area 112, that is, the display area 112 surrounds part of the edges of the sensor setting area 111.

[0048] For example, Figure 5 This is a schematic diagram of the structure of another display panel provided by an embodiment of the present invention. Figure 5 In the display panel 10 , the sensor setting area 111 is square in shape and is located at the upper edge of the display area 112 , that is, the display area 112 surrounds the left, right and lower edges of the sensor setting area 111 .

[0049] It should be noted that Figure 3 Only a circular sensor setting area 111 is shown as an example. Figure 5The figure shows only a square sensor arrangement area 111, which does not limit the display panel 10 provided by the embodiment of the present invention. In other embodiments, the shape and number of sensor arrangement areas 111, as well as their relative positional relationship with the display area 112, can be set according to the actual requirements of the display panel 10, and the embodiment of the present invention does not limit this.

[0050] Secondly, it should be noted that Figure 4 The diagram only illustrates the film layers in each region of the sensor arrangement area 111, which are all visually visible. This is merely to clearly illustrate the relative positional relationships of the regions in the sensor arrangement area 111 and does not constitute a limitation on the longitudinal (herein, "longitudinal" is understood to be a direction perpendicular to the plane of the substrate of the display panel 10) film layer structure of the display panel 10. In other embodiments, the longitudinal film layer structure of the display panel 10 can be configured according to the actual needs of the display panel 10, and this embodiment of the present invention is not limited thereto.

[0051] Optional, Figure 6 For the Figure 4 The cross-sectional structure diagram of A1-A2, Figure 7 A schematic cross-sectional view of another display panel provided by an embodiment of the present invention. Figure 4-Figure 7 , the film parameters of each photosensitive element setting area 113 are the same.

[0052] The film parameters include all parameters that can characterize the film performance and are related to the total transmittance of the film in the photosensitive element placement area 113. For example, the film parameters may include the number of film layers, the film formation sequence, the material of each film layer, the thickness of each film layer, the light transmittance of each film layer, and other film parameters known to those skilled in the art, which are not limited in this embodiment of the present invention.

[0053] By setting the film parameters of each photosensitive element setting area 113 to be the same, it is possible to ensure that the light transmittance of each photosensitive element setting area 113 is the same, thereby facilitating ensuring that the sensor module has a better photosensitivity effect.

[0054] For example, continue to refer to Figure 6 and Figure 7 The film layers stacked in sequence on one side of the first base substrate 200 include a first transparent layer 201 , a second transparent layer 202 , a third transparent layer 203 and a fourth transparent layer 204 . Figure 6 In each photosensitive element setting area 113, two film layers are provided, namely a third transparent layer 203 and a fourth transparent layer 204; Figure 7In the embodiment, three film layers are provided in each photosensitive element setting area 113, namely, a second transparent layer 202, a third transparent layer 203, and a fourth transparent layer 204; these are all exemplary descriptions and do not constitute a limitation on the display panel 10 provided by the embodiment of the present invention. In other embodiments, the number of film layers and other film layer parameters of the photosensitive element setting area 113 can be set according to the actual needs of the display panel 10, and the film layer structure of other areas in the sensor setting area 111 other than the photosensitive element setting area 113 can be set. For example, it can include film layers related to the driving circuit and film layers related to the light-emitting unit. For example, it can be provided with metal wiring layers, metal electrode layers, and other non-transparent film layers. The embodiment of the present invention does not limit this, and it is sufficient to ensure that the film layer parameters of each photosensitive element setting area 113 are the same.

[0055] Optional, continue to refer to Figure 3-Figure 5 , the sensor setting area 111 also includes an auxiliary display area 114 (exemplarily, Figure 4 The area corresponding to the auxiliary display area 114 is shown by a bold dotted line); a first light-emitting unit 121 is provided in the display area 112, and a second light-emitting unit 122 is provided in the auxiliary display area 114.

[0056] The display area 112 emits light to display images via the first light-emitting unit 121, and the auxiliary display area 114 emits light to display images via the second light-emitting unit 122. By providing the sensor setting area 111 with the auxiliary display area 114, the sensor setting area 111 can realize display. Combining this with the display of the display area 112 can increase the proportion of the area of ​​the display panel 10 that can be used to display images, that is, improve the screen-to-body ratio, thereby facilitating full-screen display of the display panel 10, that is, facilitating the realization of a true full-screen display.

[0057] Exemplarily, the first light-emitting unit 121 and the second light-emitting unit 122 can be any light-emitting unit known to those skilled in the art, and can be, for example, an organic light-emitting unit, a liquid crystal display light-emitting unit, a Mini-LED or a Micro-LED, which is not limited in the embodiment of the present invention.

[0058] Optional, continue to refer to Figure 3-Figure 5 The first light-emitting unit 121 and the second light-emitting unit 122 are both organic light-emitting units; the arrangement density of the first light-emitting units 121 in the display area 112 is greater than the arrangement density of the second light-emitting units 122 in the sensor setting area 111.

[0059] Organic light-emitting units (OLEDs) are also referred to as organic light-emitting diodes (OLEDs). When organic light-emitting units are formed in different regions of the same display panel 10, the size of each unit is typically the same. In this case, if the density of the organic light-emitting units is high, the spacing between adjacent units is small. Conversely, if the density of the organic light-emitting units is low, the spacing between adjacent units is large.

[0060] For example, the size of the organic light-emitting unit can be 20 μm to 200 μm. Using pixel density (PPI) to characterize the arrangement density of the organic light-emitting units, in the display area 112, the PPI of the first light-emitting unit 121 can be 400 to 500, and in the sensor setting area 111, the PPI of the second light-emitting unit 122 can be 20 to 500. Within the above PPI range, the arrangement density of the organic light-emitting elements in the display area 112 is greater than that in the sensor setting area 111.

[0061] The above-mentioned setting can make the intervals between the second light-emitting units 122 in the sensor setting area 111 larger under the premise that the size of the organic light-emitting units is consistent. As a result, the area reserved for arranging the photosensitive element setting area 113 is larger, which is beneficial to increase the total amount of light transmittance and improve the photosensitivity effect of the sensor module.

[0062] It should be noted that Figure 3 and Figure 5 The arrangement of the first light-emitting units 121 is merely illustrative and does not limit the display panel 10 provided in the embodiment of the present invention. In other embodiments, the arrangement of the first light-emitting units 121 in the display area 112 and the arrangement of the second light-emitting units 122 in the sensor arrangement area 111 can be configured according to the actual requirements of the display panel 10, and the embodiment of the present invention does not limit this.

[0063] Optional, continue to refer to Figure 3-Figure 5 The first light-emitting unit 121 is an organic light-emitting unit, and the second light-emitting unit 122 is a Micro-LED; the arrangement density of the first light-emitting unit 121 in the display area 112 is equal to the arrangement density of the second light-emitting unit 122 in the sensor setting area 111.

[0064] Among them, the size of the organic light-emitting unit is relatively large (for example, the size is on the order of hundreds of microns), and the size of the Micro-LED is relatively small (for example, the size is on the order of several microns to tens of microns). Therefore, at the same arrangement density, by setting the second light-emitting unit 122 as a Micro-LED, a larger area can still be reserved in the sensor setting area 111 to arrange the photosensitive element setting area 113, which is conducive to ensuring a higher total amount of light transmittance, and thus is conducive to improving the photosensitivity of the sensor module. At the same time, by setting the arrangement density of the organic light-emitting units in the display area 112 to be the same as the arrangement density of the Micro-LEDs in the photosensitive element setting area 111, that is, the PPI within the area range of the entire display panel 10 that can be used to display images is consistent, thereby enabling the display panel 10 to have a better image display effect.

[0065] For example, the arrangement density is represented by PPI. The PPI of the display area 112 and the PPI of the sensor setting area 111 can both be 400, 450, or other values ​​known to those skilled in the art. They can be set according to the actual needs of the display panel 10, and the embodiments of the present invention are not limited to this.

[0066] Optional, Figure 8 A schematic structural diagram of a sensor setting area of ​​another display panel provided by an embodiment of the present invention is shown. Figure 9 A schematic cross-sectional view of another display panel provided by an embodiment of the present invention, namely, Figure 8 Schematic diagram of the cross-section structure of B1-B2. Figure 8 and Figure 9 The display panel 10 further includes a first base substrate 200 and a transparent functional film layer ( Figure 9 The third transparent layer 203 and the fourth transparent layer 204 are shown as examples); at least a portion of the transparent functional film layer ( Figure 9 In the figure, taking the fourth transparent layer 204 as an example, a hollow pattern is provided at the same position, and the photosensitive element setting area 113 is located in the hollow area 211 of the hollow pattern.

[0067] Among them, the first base substrate 200 can be a flexible substrate or a rigid substrate, and its light transmittance can meet the photosensitivity requirements of the under-screen sensor module. The embodiment of the present invention does not limit the material type of the first base substrate 200.

[0068] The transmittance of each transparent functional film layer is greater than 40%. For example, taking the complete structure of an organic light-emitting display panel formed on a glass substrate as an example, the transparent functional layer can be any transparent film layer related to the driving circuit or the organic light-emitting unit known to those skilled in the art, and the embodiments of the present invention are not limited thereto.

[0069] The hollow patterns are arranged at the same position, which can also be understood as that when the hollow patterns of the transparent functional film layers are vertically projected onto the plane where the first base substrate 200 is located, the vertical projection positions of the hollow patterns of each transparent functional film layer are the same.

[0070] With such a configuration, while ensuring that the transmittance of each photosensitive element setting area 113 is the same, the number of film layers in the photosensitive element setting area 113 is reduced, thereby reducing the total amount of light absorbed, which is beneficial to increasing the light transmittance of the photosensitive element setting area 113, thereby improving the photosensitivity effect of the sensor module.

[0071] First of all, it should be noted that Figure 8 The illustration only illustrates that the hollow region 211 and the photosensitive element placement area 113 have the same shape, both being the combined shape of two rounded rectangles. This does not limit the display panel 10 provided in the embodiment of the present invention. In other embodiments, the shapes of the hollow region 211 and the photosensitive element placement area 113 may be configured to be the same or different, depending on the actual needs of the display panel 10. It is sufficient to ensure that the photosensitive element placement area 113 is disposed within the hollow region 211 of the hollow pattern, and this is not limited in the embodiment of the present invention.

[0072] Secondly, it should be noted that Figure 9 The hollow pattern formed in the fourth transparent layer 204 is shown for exemplary purposes only and does not limit the display panel 10 provided in the embodiment of the present invention. In other embodiments, two or more transparent functional film layers may be provided with hollow patterns at the same position, depending on the actual needs of the display panel 10. The transparent functional layers provided with hollow patterns may be provided adjacent to each other or spaced apart, and this is not limited in the embodiment of the present invention.

[0073] Optional, Figure 10 A schematic cross-sectional structure diagram of another display panel provided in an embodiment of the present invention shows a Figure 8 Another cross-sectional structural diagram of B1-B2, Figure 11 A schematic cross-sectional structure diagram of another display panel provided in an embodiment of the present invention shows a Figure 8 Another cross-sectional structural diagram of B1-B2. Figure 8 and Figure 10 , or combined Figure 8 and Figure 11 The display panel 10 further includes a touch electrode layer 205; the touch electrode layer 205 includes a plurality of sub-touch electrodes 2051, and each sub-touch electrode 2051 is provided with a hollow pattern in the sensor setting area 111; at least part of the photosensitive element setting area 113 is located in the hollow area 212 of the hollow pattern.

[0074] The touch electrode layer 205 is used to implement a touch function. Thus, on the basis that the display panel 10 can be used to display images, the display panel 10 also integrates a touch function, thereby improving user experience.

[0075] For example, the touch electrode layer 205 may implement touch control based on the mutual capacitance touch principle or the self capacitance touch principle, which is not limited in the embodiment of the present invention.

[0076] For example, Figure 10 In the figure, 212 is used as an example to represent the hollow area of ​​the hollow pattern in the sub-touch electrode 2051, and 211 is used to represent the hollow area of ​​the hollow pattern in other transparent functional film layers.

[0077] Among them, by setting a hollow pattern in the sub-touch electrode 2051 and setting the photosensitive element setting area 113 in the hollow area 212 of the hollow pattern, for the display panel 10 with touch function, the touch electrode layer 205 can reduce the shielding of light incident from the environment to the sensor module, which is beneficial to increase the total amount of light that the sensor module can receive, thereby helping to improve the photosensitivity effect of the sensor module.

[0078] For example, Figure 12 This is a structural diagram of another display panel sensor setting area provided by an embodiment of the present invention. Figure 12 , the dotted line represents the outline of the sub-touch electrode 2051, including the outer outline and inner outline of the sub-touch electrode 2051; wherein the outer outline encloses and defines the total volume occupied by the sub-touch electrode 2051 and the hollow area within the sub-touch electrode 2051; the inner outline (exemplary, Figure 12 The inner outline (shown by a bold dashed line) encloses and defines a hollow area 212. For example, a photosensitive element placement area can be provided within each hollow area 212. In subsequent manufacturing processes, a photosensitive element 310 can be placed in each photosensitive element placement area, and each sensor module can be composed of multiple photosensitive elements 310. This ensures that each photosensitive element 310 receives consistent light information, thereby improving the sensor module's light sensing performance.

[0079] First of all, it should be noted that Figure 10 and Figure 11 The second base substrate 210 is also shown in the figure. The relative position relationship between the touch electrode layer 205 and the second base substrate 210 is described in detail below.

[0080] Secondly, it should be noted that Figure 12Only one sub-touch electrode 2051 is shown for example, and the sub-touch electrode 2051 is provided with 20 hollow regions, each of which is hexagonal in shape. However, this does not limit the display panel 10 provided in this embodiment of the present invention. In other embodiments, the shape of the sub-touch electrode 2051, as well as the number, arrangement, and shape of the hollow regions in the sub-touch electrode 2051, can be configured according to the actual requirements of the display panel 10, and this embodiment of the present invention does not limit this.

[0081] Optional, Figure 13 This is a structural diagram of another display panel sensor setting area provided by an embodiment of the present invention. Figure 13 At least part of the photosensitive element setting area 113 is also set in the interval 213 between adjacent sub-touch electrodes 2051.

[0082] There is no touch electrode layer in the gaps 213 between adjacent sub-touch electrodes 2051, nor is there a touch electrode layer in the hollowed-out areas 212 of the hollowed-out pattern in each sub-touch electrode 2051. That is, the light transmittance of the area corresponding to the gaps 213 between adjacent sub-touch electrodes 2051 and the hollowed-out areas 212 in the sub-touch electrodes 2051 are equal. When the gaps 213 between adjacent sub-touch electrodes 2051 are large enough to accommodate the photosensitive element 310, the photosensitive element arrangement area 113 can also be arranged in the gaps 213 between adjacent sub-touch electrodes 2051. This ensures that the transmittance of each photosensitive element arrangement area 113 is consistent, thereby facilitating a uniform arrangement of the photosensitive element arrangement areas 113 within the plane of the display panel 10, thereby improving the light-sensing effect of the sensor module.

[0083] For example, Figure 13 Taking the orientation shown in as an example, the upper left dotted line defines one sub-touch electrode 2051, and the lower right dotted line defines another sub-touch electrode 2051, and the two sub-touch electrodes 2051 are adjacently arranged; illustratively, Figure 13The dividing line 214 in the figure illustrates the boundary between the two sub-touch electrodes 2051. This dividing line 214 is merely for the purpose of more clearly demarcating the two sub-touch electrodes 2051 and is not an actual structure within the display panel 10. Each sub-touch electrode 2051 is provided with a hollow region 212. The sensor arrangement area 113 is provided within the hollow region 212 of the sub-touch electrode 2051 and within the gaps 213 between adjacent sub-touch electrodes 2051. This is merely an exemplary description of the display panel 10 provided in the embodiment of the present invention and does not constitute a limitation on the display panel 10 provided in the embodiment of the present invention. In other embodiments, the arrangement of the sub-touch electrodes 2051 and the relative positional relationship between the sensor arrangement area 113 and the sub-touch electrodes 2051 may be further configured based on the actual requirements of the display panel 10, ensuring that the light transmittance of each sensor arrangement area 113 is equal. This embodiment of the present invention is not limited in this regard.

[0084] Optional, continue to refer to Figure 10 or Figure 11 The display panel 10 further includes a second base substrate 210 ; the touch electrode layer 205 is disposed on one side of the second base substrate 210 .

[0085] Among them, taking the organic light-emitting display panel as an example, by setting the touch electrode layer 205 on one side of the second base substrate 210 and setting the functional film layer related to the driving circuit and the organic light-emitting unit on one side of the first base substrate 200, the display function and the touch function of the display panel 10 can be independently implemented on the first base substrate 200 and the second base substrate 210, thereby reducing the mutual interference between the touch signal and the display signal, which is conducive to ensuring that the display panel 10 has both good image display effect and good touch effect.

[0086] For example, continue to refer to Figure 10 The first base substrate 200 and the second base substrate 210 are arranged opposite to each other. The functional film layers related to the driving circuit and the organic light-emitting unit are arranged on the side of the first base substrate 200 close to the second base substrate 210, and the touch electrode layer 205 is arranged on the side of the second base substrate 210 close to the first base substrate 200.

[0087] For example, continue to refer to Figure 11 , Figure 11 and Figure 10 The difference is that the touch electrode layer 205 is arranged on the side of the second base substrate 210 away from the first base substrate 200, and an insulating protection layer is further provided on the side of the touch electrode layer 205 away from the second base substrate 210 to provide insulation protection for the touch electrode layer 205.

[0088] It should be noted that Figure 10The hollow area 212 in the sub-touch electrode 2051 is shown as an example, and the size of the hollow area 211 in other transparent functional layers is comparable. Figure 11 The hollowed-out region 212 in the sub-touch electrode 2051 is shown for example only, and no hollowed-out region is provided in the third transparent layer 203 or the fourth transparent functional layer 204. However, this does not limit the display panel 10 provided by this embodiment of the present invention. In other embodiments, the film layer that needs to form the hollowed-out region can be provided according to the actual requirements of the display panel 10, so long as the film layer parameters in each photosensitive element placement area 113 are the same.

[0089] Optional, Figure 14 A structural diagram of another display panel sensor setting area provided by an embodiment of the present invention is shown. Figure 15 This is a structural diagram of another display panel sensor setting area provided by an embodiment of the present invention. Figure 14 and Figure 15 , the vertical projections of the sub-touch electrodes 2051 on the first base substrate 200 are all located in the auxiliary display area 114; the gaps 2052 between adjacent sub-touch electrodes 2051 are set in the area of ​​the auxiliary display area 114 where the second light-emitting unit is not set.

[0090] The auxiliary display area 114 is a region of the sensor arrangement area 111 with low light transmittance. This region is typically opaque, i.e., has a light transmittance of 0%. For example, the auxiliary display area 114 may include a sub-pixel region and a wiring region. The sub-pixel region may be used to house the second light-emitting unit and its pixel driver circuit, while the wiring region may be used to route signal lines. These signal lines may include data lines, scan lines, and other types of signal lines known to those skilled in the art, and are not limited in this embodiment of the present invention.

[0091] By setting the vertical projections of the sub-touch electrodes 2051 on the first base substrate 200 to be located within the auxiliary display area 114, the sub-touch electrodes 2051 no longer occupy other areas of the display panel 10 except the auxiliary display area 114, so that all areas outside the auxiliary display area 114 can be set as the photosensitive element setting area 113, which is beneficial to increase the area of ​​the photosensitive element setting area 113, thereby increasing the photosensitivity effect of the sensor module and improving the photosensitivity accuracy of the sensor module.

[0092] Exemplarily, the area in the auxiliary display area 114 where the second light-emitting unit is not provided may include the routing area and the area where the pixel driving circuit of the second light-emitting unit is located. By setting the gap 2052 between adjacent sub-touch electrodes 2051 in the area in the auxiliary display area 114 where the second light-emitting unit is not provided, on the basis of the above-mentioned increase in the area of ​​the photosensitive element setting area 113, the light-emitting effect of the second light-emitting unit is not affected, thereby ensuring that the display panel 10 has a better image display effect.

[0093] Optional, Figure 16 A schematic diagram of the structure of another display panel sensor setting area provided by an embodiment of the present invention is shown. Figure 17 This is a structural diagram of another display panel sensor setting area provided by an embodiment of the present invention. Figure 16 and Figure 17 The vertical projection of the sub-touch electrodes 2051 on the first base substrate 200 covers the auxiliary display area 114 ; the gaps between adjacent sub-touch electrodes 2051 are set in the area of ​​the sensor setting area 111 except the photosensitive element setting area 113 .

[0094] This configuration allows the gaps between adjacent sub-touch electrodes 2051 to avoid the photosensitive element setting area 113 , thereby ensuring that each photosensitive element setting area 113 is covered by the touch electrodes, that is, the light transmittance of all photosensitive element setting areas 113 is the same.

[0095] In addition, the sub-touch electrode 2051 has a larger area, which is beneficial to improving the sensing intensity of the touch signal, and further beneficial to improving the touch sensitivity and touch accuracy.

[0096] Exemplarily, the gap between adjacent sub-touch electrodes 2051 may be perpendicular to the extension direction of the routing area and span the routing area in the short side direction of the routing area; or, the gap between adjacent sub-touch electrodes 2051 may also be located between the photosensitive element setting area 113 and the routing area, and / or between the photosensitive element setting area 113 and the sub-pixel area, or may also be located in other areas known to those skilled in the art, avoiding the photosensitive element setting area 113. The embodiments of the present invention are not limited to this.

[0097] For example, the size of the sub-touch electrodes 2051 can be 2 mm to 10 mm, the spacing between adjacent sub-touch electrodes can be 20 μm to 500 μm, and the size of the sub-pixel area can be 20 μm to 200 μm. The shape of the photosensitive element arrangement area 113 can be a direction, and its aspect ratio can be 0.2 to 1. This is merely an exemplary description of the display panel 10 provided in an embodiment of the present invention. In other embodiments, the sizes of the above-mentioned structures can be set according to the actual requirements of the display panel 10, and the embodiment of the present invention is not limited to this.

[0098] It should be noted that Figure 16 and Figure 17 The partial structure of the sub-touch electrodes 2051 and the arrangement of the photosensitive element placement areas corresponding to the partial structure are merely illustrative, and do not limit the display panel 10 provided by the embodiment of the present invention. In other embodiments, the shape and arrangement of the sub-touch electrodes 2051, the spacing between adjacent sub-touch electrodes 2051, and the shape and arrangement of the photosensitive element placement areas 113 corresponding to the sub-touch electrodes 2051 can be further configured according to the actual requirements of the display panel 10, and the embodiment of the present invention does not limit these.

[0099] Optional, Figure 18 A schematic diagram of another display panel sensor setting area provided by an embodiment of the present invention. Figure 3 and Figure 18 The display panel 10 further includes a first base substrate 200 and a support column 123 disposed on one side of the first base substrate 200 ; the support column 123 is disposed in an area of ​​the sensor setting area 111 excluding the photosensitive element setting area 113 .

[0100] The presence of support columns 123 affects the light transmittance of the area in which they are located. Placing support columns 123 away from photosensitive element placement area 113 prevents their impact on the light transmittance of photosensitive element placement area 113, thereby ensuring uniform light transmittance across photosensitive element placement area 113. Furthermore, by providing support columns 123 to support the film structure above support columns 123 in the display panel 10, both the display stability of the display panel 10 and the photosensitivity stability of the sensor module are ensured. This improves the photosensitivity of the sensor module while preventing water ripples on the display.

[0101] For example, the sensor setting area 111 of the display panel 10 includes not only the photosensitive element setting area 113 but also an auxiliary display area 114. The auxiliary display area 114 may include a sub-pixel area and a wiring area. The second light-emitting unit and the pixel driving circuit of the second light-emitting unit may be set in the sub-pixel area. Figures 19-25 The positions where the support columns 123 may be disposed are exemplified.

[0102] For example, Figure 19 This is a structural diagram of another display panel sensor setting area provided by an embodiment of the present invention. Figure 19 , the support columns 123 are all located in the wiring area, so that the area of ​​the photosensitive element setting area 113 is larger and the transmittance is the same.

[0103] For example, Figure 20A structural diagram of another display panel sensor setting area provided by an embodiment of the present invention is shown. Figure 21 This is a structural diagram of another display panel sensor setting area provided by an embodiment of the present invention. Figure 20 and Figure 21 , the auxiliary display area 111 is also provided with a plurality of signal lines; the signal lines include a first signal line 131 extending along a first direction X and a second signal line 132 extending along a second direction Y, and the first direction X intersects with the second direction Y; the support column 123 is provided at the intersection of the first signal line 131 and the second signal line 132. For example, the first signal line 131 represents the first routing area, and the second signal line 132 represents the second routing area, then the support columns 123 are all located at the intersection of the first routing area and the second routing area, thereby, the distribution of the support columns 123 is relatively uniform, which is conducive to achieving uniform support for the sensor setting area 111. Comparison Figure 20 and Figure 21 It can be seen that Figure 20 The distribution of the middle support columns 123 is relatively dense. Figure 21 The distribution of the support columns 123 is relatively sparse, which is merely an exemplary description of the arrangement density of the support columns 123 and does not constitute a limitation on the display panel 10 provided by the embodiment of the present invention. In other embodiments, the number and arrangement density of the support columns 123 can be set according to the actual requirements of the display panel 10, and the embodiment of the present invention does not limit this.

[0104] For example, Figure 22 This is a structural diagram of another display panel sensor setting area provided by an embodiment of the present invention. Figure 22 The support pillars 123 can all be located within the sub-pixel regions (illustrated by the second light-emitting unit 122) of the auxiliary display area, with one support pillar 123 disposed within each sub-pixel region. Because the sub-pixel region is larger than the trace area, locating the support pillars 123 within the sub-pixel region can also reduce the difficulty of positioning and manufacturing the support pillars 123.

[0105] For example, Figure 23 This is a structural diagram of another display panel sensor setting area provided by an embodiment of the present invention. Figure 23 The sub-pixel regions can be divided into first color sub-pixel regions, second color sub-pixel regions, and third color sub-pixel regions according to the luminous color. The support pillars 123 can also be located in two of the sub-pixel regions of these colors. Exemplarily, the support pillars 123 are disposed in both the second color sub-pixel region and the third color sub-pixel region, but not in the first color sub-pixel region.

[0106] For example, Figure 24 This is a structural diagram of another display panel sensor setting area provided by an embodiment of the present invention. Figure 24 ,and Figure 23 The similarities are that the sub-pixel regions can be divided into three sub-pixel regions of different luminescent colors according to the luminescent color; the difference is that the support pillars 123 are disposed in all sub-pixel regions of the same color. For example, the support pillars 123 are disposed in the second-color sub-pixel region, but not in the first-color sub-pixel region and the third-color sub-pixel region.

[0107] For example, Figure 25 This is a structural diagram of another display panel sensor setting area provided by an embodiment of the present invention. Figure 25 , and Figure 23 and Figure 24 The similarities are not repeated here, but the difference is that the support pillars 123 are only provided in some sub-pixel areas of the same color. For example, the support pillars 123 are only provided in some sub-pixels of the second color sub-pixel area, while the support pillars 123 are not provided in another part of the second color sub-pixel area and all of the first color sub-pixel area and the third color sub-pixel area.

[0108] It should be noted that the second light emitting unit 122 can represent the sub-pixel area in the sensor setting area 111. In this way, optionally, continue to refer to Figure 22-Figure 25 In any of the figures, at least a portion of the second light-emitting unit 122 is provided with a support column 123 ; the support column 123 does not overlap with the light-emitting area of ​​the second light-emitting unit 122 .

[0109] The pixel driving circuit of the second light-emitting unit 122 can also be disposed in the area represented by the second light-emitting unit 122. By arranging that the support column 123 does not overlap with the light-emitting area of ​​the second light-emitting unit 122, the support column 123 does not affect the light emission effect of the second light-emitting unit 122, thereby ensuring that the display panel 10 has a better image display effect.

[0110] Optional, continue to refer to Figure 23-25 In any figure, the second light-emitting unit 122 includes a first color light-emitting unit 1221, a second color light-emitting unit 1222 and a third color light-emitting unit 1223; the support column 123 is arranged in at least a portion of the second light-emitting unit 122 of at least one color among the first color light-emitting unit 1221, the second color light-emitting unit 1222 and the third color light-emitting unit 1223.

[0111] The first, second, and third colors work together to enable the display panel 10 to display images normally. For example, the first, second, and third colors can each be one of red, green, and blue; or they can be other colors known to those skilled in the art, which are not limited in this embodiment of the present invention. In other embodiments, depending on the actual display requirements of the display panel 10, the second light-emitting unit 122 can further include a fourth color light-emitting unit or more light-emitting units of different colors, which are not limited in this embodiment of the present invention.

[0112] For example, the support column 123 may be located only in part of the second light emitting units 122 of the same color; Figure 25 , the support column 123 is only located in part of the second color light emitting units 1222. Alternatively, the support column 123 may be only located in all the second light emitting units 122 of the same color; Figure 24 , the support column 123 is only located in all the second color light emitting units 1222. Alternatively, the support column 123 can be located in part of the second light emitting units 122 of different colors; Figure 23 , the support column 123 is located in the second color light emitting unit 1222 and the third color light emitting unit 1223. Alternatively, the support column 123 may be located in all the second light emitting units 122; Figure 22 Each first-color light-emitting unit 1221, second-color light-emitting unit 1222, and third-color light-emitting unit 1223 is provided with a support column 123. This is merely an exemplary description of the position of the support column 123 and does not limit the display panel 10 provided in this embodiment of the present invention. In other embodiments, the relative positional relationship between the support column 123 and the light-emitting units of different colors in the second light-emitting unit 122 can be set according to the actual requirements of the display panel 10, and this embodiment of the present invention is not limited to this.

[0113] It should be noted that the above Figures 19-25 The support columns 123 are shown as having a square planar shape, and the number and spacing of the support columns 123 are shown as examples, but these examples do not limit the display panel 10 provided in the embodiment of the present invention. In other embodiments, the number, shape, and spacing of the support columns 123 can be set according to the actual requirements of the display panel 10, and the embodiment of the present invention does not limit these.

[0114] Optional, continue to refer to Figure 18 , the support columns 123 are also arranged in the display area 112 ; the arrangement density C1 of the support columns 123 in the sensor setting area 111 is the same as the arrangement density C2 of the support columns 123 in the display area 112 .

[0115] This arrangement ensures that the arrangement density of the support columns 123 is uniform across the entire display panel 10, thereby facilitating consistent support of the support columns 123 at various locations on the display panel 10, thereby ensuring a better image display quality on the display panel 10. Furthermore, by maintaining a consistent arrangement density of the support columns 123, the arrangement of the support columns 123 becomes more regular, thereby reducing the design and manufacturing difficulty of the display panel 10.

[0116] It should be noted that Figure 18 The number of support columns 123 in the display area 112 and the sensor setting area 111 is shown as 5 for example. This is only a local structure of the display panel 10 and does not constitute a limitation on the display panel provided by the embodiment of the present invention. In other embodiments, the number of support columns 123 in the display area 112 and the sensor setting area 111 can be set according to the actual needs of the display panel 10. For example, the ratio of the arrangement density C1 of the support columns 123 in the sensor setting area 111 to the arrangement density of the support columns 123 in the display area 112 can also meet This embodiment of the present invention is not limited to this.

[0117] Optional, Figure 26 A schematic structural diagram of another display panel provided by an embodiment of the present invention is shown. Figure 27 A schematic cross-sectional view of another display panel provided by an embodiment of the present invention. Figure 3 、 Figure 26 as well as Figure 27 The display area 112 includes a first touch electrode structure 141, and the sensor setting area 111 includes a second touch electrode structure 142; the first touch electrode structure 141 and the second touch electrode structure 142 are arranged in different film layers; the first touch electrode structure 141 is used to detect the touch position in the display area 112, and the second touch electrode structure 142 is used to detect the touch position in the sensor setting area 111.

[0118] The first touch electrode structure 141 and the second touch electrode structure 142 are combined to implement touch detection within the entire display panel 10 area.

[0119] For example, the first touch electrode structure 141 may be an embedded structure, and the second touch electrode structure 142 may be an on-cell structure or an external structure.

[0120] Optional, continue to refer to 3. Figure 26 as well as Figure 27 The first touch electrode structure 141 is a mutual-capacitive touch electrode structure, and the second touch electrode structure 142 includes a self-capacitive touch electrode block 1421 ; the self-capacitive touch electrode block 1421 completely covers the sensor setting area 111 .

[0121] A mutual-capacitive touch electrode structure is provided in the display area 112, resulting in better touch performance and higher sensitivity. A self-capacitive touch electrode structure is provided at a location corresponding to the sensor setting area 111, and the self-capacitive touch electrode block 1421 is used to completely cover the sensor setting area 111. This allows the self-capacitive touch electrode block 1421 to serve as the lower electrode and the user's finger as the upper electrode to achieve touch detection in the sensor setting area 111. This solves the problem of touch failure that may occur when mutual-capacitive touch is used at this location when the sensor setting area 111 is large. Furthermore, the self-capacitive touch electrode can completely cover the sensor setting area 111, so that each photosensitive element setting area in the sensor setting area 111 is provided with a self-capacitive touch electrode block 1421. This ensures that the light transmittance of each photosensitive element setting area is the same, thereby improving the photosensitivity of the sensor module.

[0122] Optional, continue to refer to Figure 27 The display panel 10 also includes a first base substrate 200, and a display layer 221 and an encapsulation layer 222 stacked on one side of the first base substrate 200. The display layer 221 includes at least one display electrode layer; the self-capacitive touch electrode block 1421 is arranged on the same layer as a display electrode layer in the display layer 221.

[0123] Among them, the display layer 221 can be understood as a film layer used to realize the normal display of images on the display panel, and may include a driving-related film layer of the light-emitting unit, a carrier transport-related film layer of the light-emitting unit, a light-emitting layer, and other film layers known to those skilled in the art, and the embodiment of the present invention is not limited to this. Among them, the display electrode layer can be understood as any film layer in the display layer 221 used to form an electrode. By utilizing the display electrode layer and the self-capacitive touch electrode block 1421 to be arranged in the same layer, the two can also be formed using the same material in the same process step, which is conducive to simplifying the film layer structure and process of the display panel 10, thereby helping to reduce the production cost of the display panel 10, and at the same time helping to achieve a lightweight and thin design of the display panel 10.

[0124] Exemplarily, the display electrode layer includes a transparent electrode layer, such as a transparent (eg, light transmittance T satisfies T≥45%) conductive oxide layer, and the self-capacitive touch electrode block 1421 can be disposed in the same layer as the transparent conductive oxide layer.

[0125] It should be noted that Figure 27 In the figure, the display layer 221 and the encapsulation layer 222 are replaced by a single film layer for exemplary purposes. In the actual structure of the display panel 10, the display layer 221 and the encapsulation layer 222 may each include multiple film layers stacked together, which may be configured according to the actual requirements of the display panel 10 and is not limited in this embodiment of the present invention.

[0126] Optional, continue to refer to Figure 27 The mutual capacitive touch electrode structure 141 is disposed on a side of the packaging layer 222 away from the first base substrate 200 .

[0127] In this way, the mutual-capacitive touch electrode structure 141 can be disposed on the side of the encapsulation layer 222 away from the display layer 221 , that is, the mutual-capacitive touch electrode structure 141 and the self-capacitive touch electrode structure 142 can be disposed in different film layers.

[0128] Optional, Figure 28 A schematic cross-sectional view of another display panel provided by an embodiment of the present invention. Figure 28 The display panel 10 further includes a second base substrate 210 , which is located on a side of the encapsulation layer 222 away from the first base substrate 200 , and the mutual capacitive touch electrode structure 141 is located between the second base substrate 210 and the encapsulation layer 222 .

[0129] The second base substrate 210 may be a protective cover plate, and the second base substrate 210 may protect the mutual capacitive touch electrode structure 141 , thereby enhancing the overall stability of the display panel 10 and extending the service life of the display panel 10 .

[0130] Alternatively, the second base substrate 210 can also be the base substrate of the mutual capacitive touch electrode structure 141, that is, the display panel 10 adopts an external touch electrode structure, thereby independently realizing the display function and touch function of the display panel 10, which is beneficial to improving the production yield of the display panel 10 and reducing costs.

[0131] It should be noted that Figure 26 The figure only shows that the touch electrodes in the mutual-capacitive touch electrode structure 141 are all prismatic, and the self-capacitive touch electrode structure 142 is circular. Figure 26 and Figure 27 The relative positional relationships of the film layers of the display panel 10 related to the embodiment of the present invention are merely illustrative, and do not constitute a limitation on the display panel 10 provided by the embodiment of the present invention. In other embodiments, the shape and arrangement of the touch electrodes in the mutual-capacitive touch electrode structure 141, the shape of the self-capacitive touch electrode structure 142, and the film layer structure of the display panel 10 may be configured according to the actual requirements of the display panel 10, and the embodiment of the present invention does not limit these.

[0132] In addition, it should be noted that, under the premise of no conflict, the structures of the display panel 10 shown in the above figures can be combined or replaced with each other, and the embodiments of the present invention are not limited to this.

[0133] Based on the above embodiments, an embodiment of the present invention further provides a display device, which includes any display panel provided in the above embodiments. Therefore, the display device also has the beneficial effects of the display panel provided in the above embodiments. The similarities can be understood by referring to the above and will not be repeated below.

[0134] For example, Figure 29 A schematic cross-sectional view of a display device according to an embodiment of the present invention is shown. Figure 30 This is a schematic diagram of a planar structure of a display device provided by an embodiment of the present invention. Figure 29 and Figure 30 The display device 30 includes a display panel 10 and a sensor module 320 correspondingly disposed in the sensor setting area 111 .

[0135] The sensor module 320 includes one or more of a camera module, a light sensor, and an ultrasonic distance sensor.

[0136] Exemplarily, the display device 30 is a mobile phone or a tablet. When the sensor module 320 is a camera module, the sensor setting area 111 corresponds to the area where the front camera of the mobile phone or tablet is located, the auxiliary display area is used for display, and the photosensitive element setting area is used to input light into the front camera for the front camera to capture external images; and when the sensor is a light sensor, the light sensor can be a light sensor used to sense external light and adjust the brightness of the display device, or it can be a light sensor used to sense whether there is a fingerprint outside, so as to perform fingerprint recognition; the light sensor also receives external light through the photosensitive element setting area of ​​the sensor setting area 111, and then performs sensing, and the auxiliary display area is used to display images together with the display area 112.

[0137] Exemplarily, the sensor module 320 can be divided into two types, in which the entire photosensitive surface of one sensor module 320 is a complete photosensitive surface; the other sensor module 320 may include multiple photosensitive sensors (sensors), which sense light through the photosensitive sensors and integrate the photosensitive information of each photosensitive sensor to obtain the photosensitive information of the sensor module 320.

[0138] For example, combined Figure 3-Figure 25 The former requires that the light transmittance at each position in the sensor setting area except the auxiliary display area is the same, that is, the sensor module 320 of this type can be used with Figure 4 、 Figure 14 、 Figure 15 as well as Figure 19-Figure 25The latter requires that the light transmittance at the location of each photosensitive sensor (ie, photosensitive element) is the same. This type of sensor module 320 can be used with Figure 3-Figure 25 The display panel 10 shown in any of the figures is combined to ensure that the sensor module 320 has a better light-sensing effect.

[0139] In addition, it should be noted that Figure 12 、 Figure 13 as well as Figure 20-25 The circular photosensitive elements (i.e., photosensors) are shown for example only, but do not limit the display panel 10 and display device 30 provided by the embodiment of the present invention. In other embodiments, the shape, number, and arrangement of the photosensitive elements can be set according to the actual requirements of the display panel 10 and display device 30, and the embodiment of the present invention does not limit them.

[0140] Exemplarily, the display device 30 may be a mobile phone, a tablet computer, a smart wearable device (eg, a smart watch), and other types of display devices known to those skilled in the art, and the embodiment of the present invention is not limited thereto.

[0141] Note that the above are only preferred embodiments of the present invention and the technical principles employed. Those skilled in the art will appreciate that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, combinations, and substitutions are possible for those skilled in the art without departing from the scope of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments and may include many other equivalent embodiments without departing from the scope of the present invention. The scope of the present invention is determined by the scope of the appended claims.
