The OLED display device not only has excellent display performance, but also has characteristics such as self-luminescence, simple structure, ultra-thin and light, fast response speed, wide viewing angle, low power consumption, and flexible display, and is known as the "dream display", which has been favored by major display manufacturers and has become the main force in the field of display technologies. There is a problem of signal crosstalk in the display panel of the existing OLED display device, which affects the quality of the product. Summary of the Invention

[0003] The purpose of the present invention is to provide a display panel and a display device, which solve the technical problem of signal crosstalk in the prior art and affecting the product quality.

[0004] To achieve this purpose, the present invention adopts the following technical solutions:

[0005] The present invention provides a display panel, including:

[0006] A substrate;

[0007] A first conductive layer, which is disposed on the substrate;

[0008] A second conductive layer, which is disposed on the first conductive layer, and a light-transmitting hole is formed in the second conductive layer;

[0009] A shielding structure, which is disposed between the first conductive layer and the second conductive layer, and the orthographic projection of the shielding structure on the substrate at least covers a part of the orthographic projection of the light-transmitting hole on the substrate.

[0010] The display panel is provided with a shielding structure between the first conductive layer and the second conductive layer, and the orthographic projection of the shielding structure on the substrate at least covers a part of the orthographic projection of the light-transmitting hole on the substrate, so as to reduce the mutual crosstalk between the touch layer and the first conductive layer caused by the setting of the light-transmitting hole.

[0081] The present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. In addition, it should be noted that, for the sake of convenience of description, only parts related to the present invention are shown in the drawings, rather than all the structures.

[0082] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0083] In the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "over", and "on top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely means that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "under", and "beneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely means that the horizontal height of the first feature is lower than that of the second feature.

[0084] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "right", etc. are based on the orientation or positional relationship shown in the drawings. It is only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0085] With the continuous development of display technology, display panels are more and more widely used. The display panel is integrated with a touch function. When a user uses the display panel, input or control operations can be directly performed through touch, making the application of the display panel more convenient.

[0086] The ViP technology (more precise pixels are achieved through semiconductor lithography process) adopts a pixel-level packaging scheme without a full-surface cathode coverage. When manufacturing the TP process, due to the light transmission requirement of the photosensitive element, a VSS hole digging design needs to be made in the display area of the cathode layer of the display panel to form a light transmission hole. At this time, due to the setting of the light transmission hole, the driving signal line will interfere with the touch signal. When the interference is too large, it may affect the touch performance of the product.

[0087] To solve the above problems, as Figure 1As shown in the figure, this embodiment provides a display panel, including a substrate 10, a first conductive layer 211, and a second conductive layer. The first conductive layer 211 is disposed on the substrate 10; the second conductive layer is disposed on the first conductive layer 211, and a light-transmitting hole 311 is formed in the second conductive layer. The light-transmitting hole 311 is disposed opposite to a photosensitive element on the back side of the display panel. A touch layer is disposed above the second conductive layer. Due to the setting of the light-transmitting hole 311, signal crosstalk is likely to occur between the touch layer and the first conductive layer 211.

[0088] To prevent signal crosstalk, the display panel further includes a shielding structure 212. The shielding structure 212 is disposed between the first conductive layer 211 and the second conductive layer, and the shielding structure 212, the first conductive layer 211, and the second conductive layer are insulated from each other. The orthographic projection of the shielding structure 212 on the substrate 10 at least covers the orthographic projection of at least part of the light-transmitting hole 311 on the substrate 10.

[0089] The display panel is provided with a shielding structure 212 between the first conductive layer 211 and the second conductive layer. The orthographic projection of the shielding structure 212 on the substrate 10 at least covers the orthographic projection of at least part of the light-transmitting hole 311 on the substrate 10, so as to reduce the mutual crosstalk between the touch layer and the first conductive layer 211 caused by the setting of the light-transmitting hole 311 and avoid the failure of the touch function.

[0090] Optionally, the shielding structure 212 is a transparent layer and does not affect the light transmittance.

[0091] Optionally, the orthographic projections of the first conductive layer 211 and at least part of the light-transmitting hole 311 on the substrate 10 have an overlapping area. Specifically, the light-transmitting hole 311 includes a first light-transmitting hole 3111 and a second light-transmitting hole 3112. The orthographic projections of the first conductive layer 211 and the first light-transmitting hole 3111 on the substrate 10 have an overlapping area, and the orthographic projections of the first conductive layer 211 and the second light-transmitting hole 3112 on the substrate 10 do not overlap; the orthographic projection of the shielding structure 212 on the substrate 10 covers the orthographic projection of the first light-transmitting hole 3111 on the substrate 10.

[0092] Further, the second conductive layer is an isolation structure layer 31, and a plurality of isolation openings are formed in the isolation structure layer 31; the display panel includes sub-pixels arranged in an array, and the sub-pixels are located in the isolation openings. The orthographic projection of the light-transmitting hole 311 on the substrate 10 does not overlap with the orthographic projection of the isolation opening on the substrate 10. In this embodiment, as Figure 2 shown, the first light-transmitting hole 3111 is disposed between two adjacent sub-pixels arranged horizontally, and the second light-transmitting hole 3112 is disposed between two adjacent sub-pixels arranged vertically.

[0093] Optionally, the display panel further includes driving signal lines that extend in the lateral direction and are disposed on the first conductive layer 211. The orthographic projection of the driving signal lines on the substrate 10 at least partially overlaps with the orthographic projection of the first light-transmitting holes 3111 on the substrate 10, that is, the arrangement of the driving signal lines cannot avoid the first light-transmitting holes 3111. Due to the existence of the first light-transmitting holes 3111, crosstalk occurs between the signals of the touch layer and the driving signals. The setting of the shielding structure 212 can prevent signal crosstalk between the two. Preferably, the driving signal lines are one of the light-emitting signal lines and the scanning signal lines.

[0094] It should be noted that since the orthographic projection of the driving signal lines on the substrate 10 does not overlap with the orthographic projection of the second light-transmitting holes 3112 on the substrate 10, that is, the arrangement of the driving signal lines can avoid the second light-transmitting holes 3112, therefore, crosstalk does not occur between the signals of the touch layer and the driving signals due to the existence of the second light-transmitting holes 3112. Therefore, there is no need to provide the shielding structure 212 at the position corresponding to the second light-transmitting holes 3112.

[0095] Optionally, the display panel further includes a first active layer 213, and the shielding structure 212 is provided on the same layer and made of the same material as the first active layer 213. In this embodiment, the first active layer 213 is located between the first conductive layer 211 and the second conductive layer, and the first active layer 213, the first conductive layer 211, and the second conductive layer are insulated from each other. The shielding structure 212 is provided on the same layer and made of the same material as the first active layer 213. Since the shielding structure 212 is provided on the same layer and made of the same material as the first active layer 213, the shielding structure 212 does not increase the manufacturing process during preparation. The first active layer 213 that is originally required to be provided is used to form the shielding structure 212, which simplifies the manufacturing process. In this embodiment, the first active layer 213 is an IGZO layer. The shielding structure 212 is also an IGZO layer. The IGZO layer has good conductivity and high light transmittance, which can not only conduct electricity to shield signals and prevent crosstalk, but also does not affect the light transmittance.

[0096] Optionally, the display panel further includes a second active layer 215, and the second active layer 215 is located between the first conductive layer 211 and the substrate 10. The shielding structure 212 is not provided on the same layer as the second active layer 215. In this embodiment, the second active layer 215 is a PSI layer.

[0097] To provide a stable potential signal for the shielding structure 212, the display panel further includes a third conductive layer 214, which is disposed between the shielding structure 212 and the second conductive layer. In this embodiment, the third conductive layer 214 is electrically connected to the shielding structure 212 and is used for signal transmission. By electrically connecting the third conductive layer 214 to the shielding structure 212, a stable potential signal can be provided for the shielding structure 212. Specifically, the third conductive layer 214 includes a power signal line, and the power signal line is electrically connected to the shielding structure 212. Preferably, the power signal line is one of a VDD signal line, a VSS signal line, or a Verf signal line, and a stable potential signal is provided for the shielding structure 212 through the third conductive layer 214.

[0098] Optionally, the third conductive layer 214 and the shielding structure 212 are electrically connected through an opening. The conductive connection between the third conductive layer 214 and the shielding structure 212 is achieved through the opening, which is relatively convenient to prepare.

[0099] It should be noted that, in order to prevent signal crosstalk between the touch layer and the driving signal line, a light-transmitting hole 311 can be provided at the corresponding position of the photosensitive element. However, in order to ensure the display consistency in the display area, a plurality of light-transmitting holes 311 are provided at the non-photosensitive element corresponding positions in the display area, that is, an array of a plurality of light-transmitting holes 311 can be provided in the display area, and a shielding structure 212 is provided at the corresponding position of each light-transmitting hole 311, which can effectively play a shielding role and can also improve the phenomenon of uneven off-screen brightness and increase the transmittance.

[0100] In a preferred embodiment, the display area of the display panel includes a first area and a second area surrounding the first area. Photosensitive elements are provided at the corresponding positions of the first area, and no photosensitive elements are provided at the corresponding positions of the second area. The light-transmitting holes 311 and the shielding structure 212 are provided in the first area and the second area.

[0101] In an embodiment, the patterns of the light-transmitting holes 311 in the first area and the second area are the same, and the relative positions are the same; the patterns of the shielding structures 212 in the first area and the second area are the same, and the relative positions are the same. Through this design, the display consistency in the display area is ensured, and the phenomenon of uneven off-screen brightness can also be improved, and the transmittance is increased.

[0102] In an embodiment, the light-transmitting hole 311 refers to the first light-transmitting hole 3111, that is, an array of a plurality of first light-transmitting holes 3111 can be provided in the first area and the second area of the display area, and a shielding structure 212 is provided at the corresponding position of each first light-transmitting hole 3111, which can effectively play a shielding role and can also improve the phenomenon of uneven off-screen brightness and increase the transmittance.

[0103] Specifically, as Figure 1As shown, the display panel includes a substrate substrate 10, a driving circuit layer 20, a pixel layer 30, a packaging layer, and a touch control layer, which are sequentially arranged from bottom to top. Among them, the packaging layer and the touch control layer are not shown in the figure.

[0104] Optionally, the driving circuit layer 20 may include a gate insulating layer 22, a capacitive insulating layer 23, a buffer layer 24, an insulating layer 25, an interlayer dielectric layer 26, a first planarization layer 27, and a second planarization layer 28, which are sequentially stacked along the thickness direction of the substrate substrate 10. A first conductive layer 211 is disposed between the capacitive insulating layer 23 and the buffer layer 24, and driving signal lines are disposed on the first conductive layer 211. A first active layer 213 is disposed between the buffer layer 24 and the insulating layer 25. The shielding structure 212 is of the same layer and the same material as the first active layer 213. A third conductive layer 214 is disposed between the insulating layer 25 and the interlayer dielectric layer 26, and a stable potential signal is provided for the shielding structure 212 through the third conductive layer 214. Specifically, the third conductive layer 214 includes a power supply signal line, and the power supply signal line is electrically connected to the shielding structure 212. Preferably, the power supply signal line is one of a VDD signal line, a VSS signal line, or a Verf signal line. The third conductive layer 214 is used to provide a stable potential signal for the shielding structure 212.

[0105] Optionally, the positive projection of the first conductive layer 211 and at least part of the light-transmitting holes 311 on the substrate substrate 10 has an overlapping area. Specifically, the light-transmitting holes 311 include a first light-transmitting hole 3111 and a second light-transmitting hole 3112. The positive projection of the first conductive layer 211 and the first light-transmitting hole 3111 on the substrate substrate 10 has an overlapping area, and the positive projection of the first conductive layer 211 and the second light-transmitting hole 3112 on the substrate substrate 10 does not overlap; the positive projection of the shielding structure 212 on the substrate substrate 10 covers the positive projection of the first light-transmitting hole 3111 on the substrate substrate 10.

[0106] Furthermore, in this embodiment, the second conductive layer is an isolation structure layer 31, and the isolation structure layer 31 is provided with a plurality of isolation openings; the display panel includes a plurality of sub-pixels arranged in an array, and the sub-pixels are located within the isolation openings. The positive projection of the light-transmitting holes 311 on the substrate substrate 10 does not overlap with the positive projection of the isolation openings on the substrate substrate 10. As Figure 2 shown, the first light-transmitting hole 3111 is disposed between two adjacent sub-pixels arranged horizontally, and the second light-transmitting hole 3112 is disposed between two adjacent sub-pixels arranged vertically.

[0107] Optionally, the positive projection of the driving signal line on the substrate 10 overlaps at least partially with the positive projection of the first light-transmitting hole 3111 on the substrate 10, that is, the arrangement of the driving signal line cannot avoid the first light-transmitting hole 3111. Due to the existence of the first light-transmitting hole 3111, crosstalk exists between the signal of the touch control layer and the signal of the driving signal line. The setting of the shielding structure 212 can prevent signal crosstalk between the two. Preferably, the driving signal line is one of a light-emitting signal line and a scanning signal line.

[0108] It should be noted that since the positive projection of the driving signal line on the substrate 10 does not overlap with the positive projection of the second light-transmitting hole 3112 on the substrate 10, that is, the arrangement of the driving signal line can avoid the second light-transmitting hole 3112, therefore, crosstalk between the signal of the touch control layer and the driving signal will not occur due to the existence of the second light-transmitting hole 3112. Therefore, there is no need to set the shielding structure 212 at the position corresponding to the second light-transmitting hole 3112.

[0109] Optionally, the pixel layer 30 includes a pixel defining layer and a light-emitting unit. The light-emitting unit includes structures such as an anode layer 33, a light-emitting layer 32, and a cathode layer (not shown in the figure). The anode layer 33 of the light-emitting unit is connected to the driving circuit of the driving circuit layer 20. The isolation structure layer 31 is disposed on the pixel layer 30. The isolation structure layer 31 overlaps with the cathode layer of the pixel layer 30 to conduct the cathode signal. A packaging layer is disposed on the isolation structure layer 31, and a touch control layer is disposed on the packaging layer.

[0110] In this embodiment, since light-transmitting holes 311 need to be provided on the isolation structure layer 31 to facilitate the light-sensitive element on the back side of the display panel to sense light. Due to the setting of the first light-transmitting hole 3111, signal crosstalk is likely to occur between the driving signal line and the touch control layer. Therefore, a shielding structure 212 is provided between the isolation structure layer 31 and the metal layer where the driving signal line is located. The shielding structure 212 is insulated from the isolation structure layer 31 and the metal layer where the driving signal line is located. The shielding structure 212 is a transparent layer. The projection of the shielding structure 212 on the substrate 10 covers the first light-transmitting hole 3111, which can prevent signal crosstalk between the touch control layer and the driving signal line.
