[0046] Various embodiments will now be described in detail with reference to the accompanying drawings, which are provided as illustrative examples of the present invention so that those skilled in the art can implement the present invention. It is noteworthy that the following drawings and examples are not meant to limit the scope of the present disclosure. In the case where a specific element of the present invention can be implemented in part or in whole using known components, only those parts of such known components required for understanding the present invention will be described, and the detailed description of other parts of such known components will be omitted so as not to confuse the present disclosure. Further, various embodiments include equivalents known to the components involved herein, both now and in the future, by way of illustration.

[0047] In the related art, the setting position of the imaging element will affect the screen-to-body ratio of the mobile terminal. Figures 1A-1C Schematically shows three relative positions of the imaging element relative to the display panel. Figure 1A In the first configuration shown, the imaging element 11 is disposed around the display panel 12, so the imaging element 11 needs to occupy additional space, which is not conducive to increasing the screen-to-body ratio. Figure 1B In the second configuration shown, the imaging element 11 is disposed on the back side of the display panel 12 (the side of the display panel away from the display surface 121), which can improve the screen-to-body ratio to a certain extent. However, this configuration requires that a blank area 13 (no pixels are set) be left at the position of the display panel 12 corresponding to the imaging element 11, and the imaging element 11 can capture the image of the object located in front of the display panel 12 through the blank area 13. Although compared with the first configuration, the second configuration can improve the screen-to-body ratio to a certain extent, it still cannot achieve full-screen display. Figure 1C In the third configuration shown, similar to the second configuration, the imaging element 11 is arranged on the back of the display panel 12, but the area of ​​the display panel 12 corresponding to the imaging element 11 is still able to display images but is at least partially transparent. In this case, the display panel includes a transparent display area 21 and a non-transparent display area 22, and the imaging element 11 is located at a position corresponding to the transparent display area 21 of the display panel. This can be achieved by reducing the ppi (pixels per inch) of the area of ​​the display panel 12 corresponding to the imaging element 11 so that ambient light can pass through the display panel 12.

[0048] Figure 2 FIG. 1 is a schematic diagram showing a partially transparent display panel in the related art. Figure 2 As shown, in order to realize partial transparent display of the display panel, some pixels can be removed in the transparent display area 21 to reduce the ppi of the transparent display area 21 (the area framed by the thick solid line in the figure). Figure 2In the diagram, pixels can be schematically represented by pixel points. As an example, the number of pixels in the transparent display area 21 can be reduced to half of that in the non-transparent display area 22. As a further example, in the transparent display area 21, rows / columns with pixels and rows / columns without pixels are arranged alternately. Figure 2 In the partially transparent display panel shown, the wiring settings in the transparent display area 21 and the non-transparent display area 22 are exactly the same, resulting in that the wiring density in the transparent display area 21 is not reduced relative to the non-transparent display area 22, which affects the transparent display effect and the imaging quality of the imaging element to a certain extent.

[0049] Figure 3 FIG. 2 is a schematic diagram showing another partially transparent display panel in the related art. Figure 3 As shown, the wirings 231 and 231 that provide signals to the pixels in the transparent display area 21 and the non-transparent display area 22 are close to each other. Figure 2 The configuration can improve the display effect and the imaging quality of the imaging element to a certain extent. However, since the spacing between the two wirings 231 and 323 close to each other in the transparent display area is usually relatively small, the smaller the gap, the easier it is for the light passing through to diffract, which will also adversely affect the display effect of the display panel and the imaging quality of the imaging element.

[0050] Figure 4A and 4B Schematically illustrate the wiring arranged along the longitudinal direction in the related art and the imaging effect diagram of the corresponding imaging element. Figure 4A and 4B As shown, when the wirings are arranged in parallel and densely, the clarity of an image captured by an imaging element is affected, so that the image quality is deteriorated.

[0051] In addition, the inventors have found through research that in addition to the density of wiring, the shape of the wiring will also affect the quality of images taken by the imaging element. Figure 5A and 5B The imaging effect diagrams of the wirings arranged in parallel and in regular strips and the corresponding imaging elements are shown respectively; Fig. 6A and 6B The following diagrams respectively show the imaging effect of irregular strip-shaped and parallel-arranged wiring and the corresponding imaging element. Figure 5A and 5B As shown in FIG. 1 , when the wiring 21 is a regular strip wiring, the imaging effect is relatively poor. Fig. 6A and 6B As shown, when the wiring 21 is an irregular strip wiring, the imaging effect is improved compared with the regular strip wiring.

[0052] In one aspect of the present disclosure, a display panel is provided. When the display panel is applied to a display device equipped with an imaging element, the diffraction effect of wiring on light can be reduced, thereby reducing the adverse effect on the imaging effect caused by the diffraction effect of wiring, while also achieving full-screen display.

[0053] Figure 7 FIG. 1 is a schematic diagram showing a partial structure of a display panel in one or more embodiments of the present disclosure. Figure 7 As shown, the display panel may include a plurality of wirings 71 extending parallel to the display surface of the display panel; and a plurality of light shielding portions 72 extending parallel to the display surface of the display panel. The projections of at least two wirings 71 with parallel extension directions among the plurality of wirings 71 on the display surface of the display panel are located within the upper projection of the same light shielding portion 72 on the display surface. At least a portion of each light shielding portion 52 has a curved profile along the extension direction.

[0054] In some embodiments of the present disclosure, the extension direction may include at least one of a first direction and a second direction intersecting the first direction. As an example, the wiring 71 may include wiring extending in the first direction and wiring extending in the second direction. As another example, the wiring may be arranged only in the first direction or only in the second direction. The first direction and the second direction may be perpendicular to each other. In some embodiments of the present disclosure, the wiring 71 may include a plurality of gate lines and a plurality of data lines, etc. A plurality of gate lines extend along one of the first direction and the second direction, and a plurality of data lines extend along the other of the first direction and the second direction. In addition, at the intersection of the wiring extending in the first direction and the wiring extending in the second direction, electronic components such as thin film transistors (TFTs) may be provided.

[0055] As a non-limiting example, both the light shielding portion 72 and the wiring 71 may be made of a metal material. In this case, an insulating layer may be provided between the light shielding portion 72 and the wiring 71 to prevent the light shielding layer from affecting the transmission signal on the wiring 71. Alternatively, the light shielding layer may also be formed of an insulating material.

[0056] When the display panel provided according to the embodiment of the present disclosure is applied to a display device equipped with an imaging element, each shading portion 72 can shield at least two wirings 71, thereby preventing ambient light from diffracting at the gap between the at least two wirings 71, thereby reducing the adverse effects of the diffraction of light on the imaging quality of the imaging element and the display effect of the display panel. In addition, objects with sharp boundaries may also diffract light. In the embodiment of the present disclosure, the shading portion is set to have a curved profile, which can at least partially eliminate the sharp boundaries of the shading portion, thereby further reducing the diffraction phenomenon of light by the shading portion.

[0057] In an exemplary embodiment, if Figure 7 As shown in FIG. 1 , the curved profile of the light shielding portion 72 has, for example, a wave shape along the extension direction of the light shielding portion 72. Figure 7 As shown, the wavy curved profile may include a plurality of wavy units 721. Since the light shielding portion with the wavy profile has a relatively smooth boundary, the diffraction phenomenon of light can be reduced, thereby improving the display effect of the display panel and the imaging quality of the imaging element.

[0058] In some embodiments, each light shielding portion 72 has a shape that is symmetrical about an axis parallel to its extension direction. In other words, the light shielding portion 72 is an axisymmetric shape. Figure 7 As shown, the wave crest of the wave unit 721 of one of the two adjacent light shielding portions 72 with parallel extension directions is aligned with the wave crest of the wave unit 721 of the other light shielding portion 72 in a direction perpendicular to the extension direction thereof. As another example, the wave crest of the wave unit 721 of one of the two adjacent light shielding portions 72 with parallel extension directions may not be aligned with the wave crest of the wave unit 721 of the other light shielding portion 72 in a direction perpendicular to the extension direction thereof. Figure 8 Schematically illustrates the alignment relationship of the peaks and valleys of adjacent wavy light shielding portions in one or more embodiments of the present disclosure. Figure 8 As shown, the wave crest of the wave unit 721 of one of the two adjacent shading portions 72 with parallel extending directions is aligned with the wave trough of the wave unit 721 of the other shading portion 72 in a direction perpendicular to the extending direction thereof.

[0059] Fig. 9 Schematically illustrates a portion of a wavy curved profile in one or more embodiments of the present disclosure. Fig. 9 As shown, the curvature radius R of each wave unit 721 at the wave crest is 5-10 μm. The width d of each wave unit 721 is 4-7 μm. In the embodiment of the present disclosure, the width of the wave unit 721 is the distance between two adjacent wave crests or wave troughs.

[0060] In some embodiments, the spacing between two adjacent shading portions with parallel extension directions is greater than 80 μm. As another embodiment, the spacing between two adjacent shading portions with parallel extension directions is greater than 120 μm. By having a large spacing between adjacent shading portions, the diffraction of light at the gaps between the shading portions can be reduced. It should be noted that in the embodiments of the present disclosure, the spacing between two adjacent shading portions 72 with the same adjacent extension directions may refer to the straight-line distance between the nearest edges of the two shading portions 72.

[0061] Fig.10 FIG. 2 is a schematic diagram showing a partial structure of another display panel in one or more embodiments of the present disclosure. Fig.10 As shown, the other display panel has a first area 101 and a second area 102, and the transmittance of the first area 101 is greater than the transmittance of the second area 102. In this embodiment, the light shielding portion 72 can be only provided in the first area 101. In an exemplary embodiment, the transmittance of the first area 101 can be increased by reducing the density of pixels in the first area 101, that is, the pixel density of the first area 101 is less than the pixel density of the second area 102. In this embodiment, the first area 101 can be used as a transparent display area of ​​the display panel, and the second area 102 can be used as a non-transparent display area of ​​the display panel.

[0062] like Fig.10 As shown, at least two wirings corresponding to the same light shielding portion 71 may include a first wiring 231 and a second wiring 232 extending along the first direction. In this embodiment, in order to improve the display effect of the transparent display area and the imaging quality of the imaging element located behind the transparent display area, the second wiring 232 is closer to the first wiring 231 in the second direction perpendicular to the first direction in the first area 101 than other wirings extending along the first direction. In addition, one of the first wiring 231 and the second wiring 232 provides a signal to the same pixel in the first area 101. That is, both the first wiring 231 and the second wiring 232 can provide signals to the pixels in the first area 101, but do not provide signals to the same pixel in the first area at the same time. In the exemplary embodiment, the first wiring 231 provides signals to the pixels in the first area 101 and the second area 102, and the second wiring 232 only provides signals to the pixels in the second area 102 but not to the pixels in the first area 101.

[0063] Fig.11 FIG. 2 is a schematic diagram showing a partial structure of another display panel in one or more embodiments of the present disclosure. Fig.11As shown, at least two wirings 23 corresponding to the same light shielding portion 72 may further include a third wiring 233 and a fourth wiring 234 extending along the second direction. In this embodiment, in order to improve the display effect of the transparent display area and the imaging quality of the imaging element located behind the transparent display area, the fourth wiring 234 is closer to the third wiring 233 in the first direction than other wirings extending along the second direction in the first area 101. In addition, one of the third wiring 233 and the fourth wiring 234 provides a signal to the same pixel in the first area 101. That is, both the third wiring 233 and the second wiring 234 can provide signals to the pixels in the first area 101, but do not provide signals to the same pixel in the first area 101 at the same time. In the exemplary embodiment, the third wiring 233 provides signals to the pixels in both the first area 101 and the second area 102, and the fourth wiring 234 only provides signals to the pixels in the second area 102 but not to the pixels in the first area 101.

[0064] In another embodiment, it is possible to combine Fig.10 and Fig.11 Specifically, the second wiring 232 is closer to the first wiring 231 in the second direction perpendicular to the first direction in the first region 101 than other wirings extending along the first direction, and the fourth wiring 234 is closer to the third wiring 233 in the first direction in the first region 101 than other wirings extending along the second direction.

[0065] Through the above configuration, the shading portion 72 blocks two adjacent wirings, which can reduce the diffraction of light caused by the gap between the two adjacent wirings; on the other hand, the use of a shading portion 72 with a curved profile can also reduce the diffraction of light by the edge of the shading portion itself, thereby further improving the display effect of the transparent display area and the imaging effect of the imaging element.

[0066] In the exemplary embodiment of the present disclosure, the first wiring 231 and the second wiring 232 may be one of a data line and a gate line, and the third wiring 233 and the third wiring 234 may be the other of the data line and the gate line. It should be noted that in the embodiment of the present disclosure, the type of wiring is not limited to the gate line and the data line, and may also include any wiring that can provide a signal to the display panel.

[0067] Fig.12 Schematically shows a cross-sectional view of a display panel in one or more embodiments of the present disclosure. Fig.12 As shown, Fig.10 and Fig.11Similar to the embodiment shown, the display panel has a first area 101 and a second area 102, and the transmittance of the first area 101 is greater than the transmittance of the second area 102. In this embodiment, the light shielding portion 72 may be disposed only in the first area 101.

[0068] The display panel may further include a first substrate 83; and a thin film transistor (TFT) 84 located on the first substrate 83. The light shielding portion 72 is located on the first substrate 83 in the first region 81 and between the thin film transistor 84 and the first substrate 83. In this configuration, the light shielding portion 72 may also reduce the adverse effect on the imaging quality of the imaging element caused by the reflection or diffraction of ambient light by the thin film transistor 84.

[0069] As a non-limiting example, the first substrate 83 may be a transparent substrate made of a light-transmitting and non-metallic material having a certain degree of durability, such as glass, quartz, transparent resin, etc. Alternatively, the first substrate 83 may be a flexible substrate made of polyimide (PI).

[0070] The display panel may further include an additional film layer 85 located in the second region 102 and extending to the first region 101. In this embodiment, the projection of the edge of the additional film layer 85 close to the first region 101 on the display surface of the display panel is located within the projection of the light shielding portion 72 on the display surface. Through this arrangement, the light incident on the imaging element located on the back of the display panel due to the edge diffraction of the additional film layer 85 can be further reduced, thereby improving the imaging quality of the imaging element. In an exemplary embodiment, the additional film layer 85 may include a planarization layer 85a and a pixel defining layer 85b.

[0071] Further Fig.12 As shown, the display panel may further include a buffer layer 86, an electrode layer 87, and a light emitting material layer 88. The buffer layer 86 is located on the light shielding portion 72. The planarization layer 85a is located on the thin film transistor 84. The electrode layer 86 is located on the planarization layer 85a. The pixel defining layer 85b has an opening area and is located on the electrode layer 87. The light emitting material layer 88 is located in the opening area of ​​the pixel defining layer 85b. In the exemplary embodiment, the electrode layer 87 is electrically connected to the source / drain of the thin film transistor through a through hole penetrating the planarization layer 85a.

[0072] exist Fig.12In the illustrated exemplary embodiment, the thin film transistor 84 is shown as a dual-gate type. In this case, the display panel may further include a first gate insulating layer 891 between the active layer of the thin film transistor 84 and the first gate G1, a second gate insulating layer 892 between the first gate insulating layer 891 and the second gate G2 of the thin film transistor, and an interlayer dielectric layer 80 between the second gate G2 of the thin film transistor and the planarization layer 85a. It is understood that in the embodiments of the present disclosure, other types of thin film transistors, such as single-gate thin film transistors, may also be used.

[0073] Fig.13 A partial structural schematic diagram of another display panel in one or more embodiments of the present disclosure is shown. Fig.13 In the illustrated embodiment, the curved profile of the light shielding portion 72 may also be a profile defined by a plurality of arcs sequentially arranged along the extension direction of the light shielding portion 72. In the one or more embodiments, the curvature directions of adjacent arcs in the plurality of arcs are opposite.

[0074] Fig.14 FIG. 2 is a schematic diagram showing a partial structure of another display panel in one or more embodiments of the present disclosure. Fig.14 As shown, the curved profile of the light shielding portion 72 can be located only at the position where the pixel driving circuit (including the driving transistor) of each pixel is located, and the projection of the pixel driving circuit on the display surface of the display panel is located within the projection of the light shielding portion on the display surface. By way of example, the curved profile of the light shielding portion 72 can have a circular or elliptical shape.

[0075] It should be noted that, in order to facilitate the description of the specific effects, advantages and feasibility of the present disclosure, the contour shape of the shading portion 72 used herein is only an example shape, and is not intended to limit the scope of the present disclosure to these specific contour shapes. With the help of these examples, those skilled in the art can easily know how to adapt the relevant parameters and conditions when adopting other curved contour shapes.

[0076] In another aspect of the disclosure, a display device is disclosed, which may include a display panel according to the present disclosure, such as a display panel according to one or more embodiments disclosed in detail above.
