The pixel circuit 200 is used to drive the light emitting element 300 to perform light-emitting display, thereby ensuring the display effect of the display panel 10 .

[0057] The pixel circuit 200 has various configuration modes. For example, Figure 2 As shown, the pixel circuit 111 is illustrated as "6T1C", where "T" represents a transistor and "C" represents a capacitor. Figure 2 As shown, the type of transistors in the pixel circuit 200 are all oxide transistors (Indium Gallium Zinc Oxide, IGZO), which have advantages such as low leakage current. In other embodiments, the type of transistors in the pixel circuit may also include low-temperature polysilicon transistors (Low Temperature Poly-Silicon, LTPS), which have advantages such as high switching speed, high carrier mobility and low power. Based on the specific configuration of the pixel circuit 200, those skilled in the art can make adaptive adjustments as needed, such as increasing or decreasing the number of transistors, or adjusting the type of transistors.

[0058] Optional, reference Figure 2As shown, the pixel circuit 200 may include a data writing transistor T1, a threshold compensation transistor T2, a driving transistor T3, a first light emission control transistor T4, a second light emission control transistor T5, a reset transistor T6 and a storage capacitor Cst. Figure 2 The timing operation process of the pixel circuit 200 provided is combined with reference to Figure 3 Give an example.

[0059] The first light-emitting control signal line (shown as EM1 in the figure) electrically connected to the control terminal of the first light-emitting control transistor T4 can control the conduction or cutoff of the first light-emitting control transistor T4. The second scanning signal line (shown as G2 in the figure) electrically connected to the control terminal of the threshold compensation transistor T2 can control the conduction or cutoff of the threshold compensation transistor T2. The third scanning signal line (shown as G3 in the figure) electrically connected to the control terminal of the reset transistor T6 can control the conduction or cutoff of the reset transistor T6. In the reset stage Ta of the pixel circuit 200, the first light-emitting control signal line (shown as EM1 in the figure) controls the conduction of the first light-emitting control transistor T4 (at this time, the scanning signal line connected to the control terminal of the first light-emitting control transistor T4 is at the enable level, Figure 3 The second scanning signal line (shown as G2 in the figure) controls the conduction of the threshold compensation transistor T2 (the scanning signal line connected to the control terminal of the threshold compensation transistor T2 is at the enable level, Figure 3 The power signal in the first power signal line PVDD connected to the input terminal of the first light-emitting control transistor T4 can be written into the gate of the driving transistor T3 through the first light-emitting control transistor T4 and the threshold compensation transistor T2, and the first node N1 is reset. Therefore, the potential of the control terminal of the driving transistor T3 is the power signal input by the first power signal line PVDD. When the driving transistor T3 is an oxide transistor, the driving transistor T3 is also in the on state. The storage capacitor Cst provided therein can ensure the stability of the potential of the first node N1. At the same time, the third scanning signal line (shown as G3 in the figure) controls the conduction of the reset transistor T6 (at this time, the scanning signal line connected to the control terminal of the reset transistor T6 is at the enable level, Figure 2 The reset signal in the reset signal line VREF electrically connected to the input terminal of the reset transistor T6 can be transmitted to the fourth node N4 to reset the light emitting element 300.

[0060] Furthermore, in the compensation preparation stage Tb, the pixel circuit 200 controls the first light-emitting control transistor T4 to be turned off by the first light-emitting control signal line (shown as EM1 in the figure) (at this time, the scanning signal line connected to the control terminal of the first light-emitting control transistor T4 is at a non-enable level, Figure 3The power signal in the first power signal line PVDD connected to the input terminal of the first light emission control transistor T4 stops being written into the pixel circuit 200.

[0061] Furthermore, the first scanning signal line (shown as G1 in the figure) electrically connected to the control terminal of the data writing transistor T1 can control the conduction or shutoff of the data writing transistor T1. In the threshold compensation stage Tc of the pixel circuit 200, the first scanning signal line (shown as G1 in the figure) controls the data writing transistor T1 to be turned on (at this time, the scanning signal line connected to the control terminal of the data writing transistor T1 is at an enable level, Figure 3 In the figure, the driving transistor T3 and the threshold compensation transistor T2 are in the on state. The data signal line VDATA connected to the input terminal of the data writing transistor T1 is sequentially written into the first node N1 through the data writing transistor T1, the driving transistor T3, and the threshold compensation transistor T2. At the same time, the third scanning signal line (shown as G3 in the figure) still controls the conduction of the reset transistor T6 to reset the light-emitting element 300.

[0062] In the light-emitting preparation stage Td of the pixel circuit 200, the first scanning signal line (shown as G1 in the figure) controls the data writing transistor T1 to be turned off (the scanning signal line connected to the control terminal of the data writing transistor T1 is at a non-enable level at this time, Figure 3 In the light emitting preparation stage Td, the second scanning signal line (shown as G2 in the figure) controls the threshold compensation transistor T2 to be turned off (the scanning signal line connected to the control terminal of the threshold compensation transistor T2 is at a non-enable level at this time). Figure 3 The data signal provided by the data signal line VDATA stops being written into the pixel circuit 200. At the same time, the third scanning signal line (shown as G3 in the figure) still controls the turn-off of the reset transistor T6 (the scanning signal line connected to the control terminal of the reset transistor T6 is at a non-enable level at this time). Figure 3 The reset of the light emitting element 300 is stopped.

[0063] Furthermore, the second light-emitting control signal line (shown as EM2 in the figure) electrically connected to the control terminal of the second light-emitting control transistor T5 can turn the second light-emitting control transistor T5 on or off. In the light-emitting stage Te of the pixel circuit 200, the first light-emitting control signal line (shown as EM1 in the figure) controls the first light-emitting control transistor T1 to be turned on, and the second light-emitting control signal line (shown as EM2 in the figure) controls the second light-emitting control transistor T5 to be turned on (at this time, the scanning signal line connected to the control terminal of the second light-emitting control transistor T5 is at the enable level, Figure 3The first power signal line PVDD and the second power signal line PVEE are turned on, that is, the driving transistor T3 generates a driving current that can be transmitted to the light emitting element 300, thereby driving the light emitting element 400 to emit light.

[0064] The display panel 10 is formed by overlapping multiple film layers. Figure 4 As shown, the film structure of the display panel 10 includes a first metal layer 101, a second metal layer 102, a semiconductor layer 103, a third metal layer 104, a fourth metal layer 105, a fifth metal layer 106 and an anode metal layer 107 from one side of the substrate 100 to the light-emitting side of the display panel 10. An insulating layer is added between two adjacent metal film layers to play the role of signal isolation and flattening. Furthermore, Figure 2 The film structure of the pixel circuit 200 provided in the embodiment adopts Figure 4 The membrane layer provided in the Figure 4 and Figure 5 As shown, the first gate BG of the transistor in the pixel circuit 200 is located in the film layer where the second metal layer 102 is located, the active layer IGZO of the transistor is located in the film layer where the semiconductor layer 103 is located, and the second gate MG of the transistor is located in the film layer where the third metal layer 104 is located; the first capacitor plate C1 included in the storage capacitor Cst in the pixel circuit 200 is located in the film layer where the first metal layer 101 is located, and the second capacitor plate C2 of the storage capacitor Cst is located in the film layer where the third metal layer 104 is located. The pixel circuit 200 is electrically connected to the anode 310 of the light-emitting element 300, and the anode 310 of the light-emitting element 310 can be located in the film layer where the anode metal layer 107 is located. For the specific film layer structure of the pixel circuit 200, it can be adaptively adjusted according to actual needs, such as adding or subtracting some film layers, and any of the above film layers can include at least one sublayer, which is not specifically limited in the embodiment of the present invention.

[0065] For further reference, Figure 5 As shown, the display panel 10 further includes an anode connecting portion 400, which is located on the side of the anode 310 close to the substrate 100. The anode connecting portion 400 is used to electrically connect the anode 310 of the light-emitting element 300 with the pixel circuit 200, ensuring that the pixel circuit 200 drives the light-emitting element 300, thereby ensuring the display function of the display panel 10. Specifically, the connection subsection 410 included in the anode connecting portion 400 is used to realize the electrical connection relationship between the pixel circuit 300 and the anode 310. Further, refer to Figure 5As shown, a compensation subsection 420 is also provided in part of the anode connection part 400 of the display panel 10. Along the thickness direction of the display panel 10, there are some areas of the compensation subsection 420 that do not overlap with the connection subsection 410. The provision of the compensation subsection 420 is equivalent to increasing the positive projection area of ​​the anode connection part 400 as a whole on the substrate. By increasing the overall area of ​​the anode connection part 400, it is beneficial to ensure that the anode 310 prepared subsequently can be more stable at this location, thereby improving the overall flatness of the display panel. It can also ensure that the light transmittance of different areas in the display panel 10 is the same or similar, ensuring that the optical effects of different areas of the display panel 10 are consistent, thereby ensuring the display effect of the display panel 10.

Figure 6 Shown, Figure 6 It can also be understood as Figure 1 Schematic diagram of a membrane layer structure in area A.

Figures 9 to 15 Used to Figure 6 The different membrane layers are illustrated from bottom to top. The subsequent instructions will explain the membrane layer settings of each part of the structure.

[0067] The position setting method of each transistor in the pixel circuit 200 and the wiring setting method electrically connected to the pixel circuit 200 can refer to Figures 6 to 15 Specific reference Figure 14 As shown, reference Figure 14 In the z1 region, the anode connection portion 400 includes a connection sub-portion 410 and a compensation sub-portion 420; Figure 14 In the z2 region, the anode connection portion 400 includes only the connection sub-portion 410. In other words, a portion of the anode connection portion 400 in the display panel 10 includes only the connection sub-portion 410, which is used to ensure the electrical connection between the light-emitting element 300 and the pixel circuit 200. At the same time, a portion of the anode connection portion 400 in the display panel 10 includes both the connection sub-portion 410 and the compensation sub-portion 420. This allows the compensation sub-portion 420 to increase the overall surface area of ​​the anode connection portion 400 while ensuring the electrical connection between the light-emitting element 300 and the pixel circuit 200. Adjusting the overall projected area of ​​the anode connection portion 400 on the substrate 100 helps improve the flatness of the overall structure of the display panel 10.

Figure 16 Shown, Figure 16 It can also be understood as Figure 1 Schematic diagram of another membrane layer structure in area A. Figure 17 for Figure 16 Schematic diagram of the nested structure of the middle membrane layer, combined with Figure 16 and Figure 17, so that we can clearly see the positional relationship of each membrane structure. Figures 18 to 24 Used to Figure 16 The different membrane layers are illustrated from bottom to top. The subsequent instructions will explain the membrane layer settings of each part of the structure.

[0069] The position setting method of each transistor in the pixel circuit 200 and the wiring setting method electrically connected to the pixel circuit 200 can refer to Figures 16 to 24 Specific reference Figure 23 As shown, the anode connection part 400 in the display panel 10 includes both a connection sub-part 410 and a compensation sub-part 420. In this way, while ensuring the electrical connection between the light-emitting element 300 and the pixel circuit 200, the entire surface area of ​​the anode connection part 400 can be comprehensively increased by the compensation sub-part 420, which is beneficial to improving the flatness of the overall structure of the display panel 10. Furthermore, each anode connection part 400 includes a compensation sub-part 420, which can ensure the uniformity of the overall structure of the display panel 10. Due to the setting of the compensation sub-part 420, it can also be ensured that the light transmittance of different areas in the display panel 10 is the same or similar, ensuring that the optical effects of different areas of the display panel 10 are consistent, and thus ensuring the display effect of the display panel 10. Furthermore, combined with Figure 14 and Figure 23 As shown, the setting of the compensation sub-portion 420 is flexible, and the connection sub-portion 410 can be adaptively compensated according to needs to improve the overall display effect of the display panel 10.

[0070] In summary, embodiments of the present invention provide a display panel comprising an anode connection portion located on the side of the anode closest to the substrate. Increasing the overall area of ​​the anode connection portion helps ensure the flatness of the film layer at the anode, thereby improving the overall flatness of the display panel. Furthermore, by adding a compensation section to increase the overall area of ​​the anode connection portion, it is also possible to ensure that light transmittance is the same or similar across different regions of the display panel, ensuring consistent optical effects across different regions of the display panel and, consequently, ensuring the display quality of the display panel.

By arranging the repeated light emitting element group in an array in the display panel 10, the overall display effect of the display panel 10 is achieved. The repeated light emitting element group can also be understood as the minimum repeating unit of the arrangement of the light emitting elements 300 in the display panel 10.

[0141] Furthermore, the anode 310 covers the anode connection portion 400 to which it is electrically connected, and the anode connection portion 400 increases its area through the compensation portion 420, which can ensure that the overall degree of padding of the light-emitting element 300 is similar, avoiding color deviation or dispersion, and thereby ensuring the display effect of the display panel 10.

[0142] Optional, Figure 35 yes Figure 1 The first cross-sectional diagram along the section line P-P', refer to Figure 35 As shown, the auxiliary structure includes support columns ps.

[0143] The auxiliary structure may include support columns ps, which can be used to support the film structure of the display panel 10 to ensure the stability of the overall structure of the display panel 10. The support columns ps can be provided independently or integrated with other film layers.

The support column can be set between the anode 310 and the substrate 100; or Figure 35 The support pillars are arranged on the side of the anode 310 away from the substrate 100; or some support pillars are arranged between the anode 310 and the substrate 100, and some support pillars are arranged on the side of the anode 310 away from the substrate 100. The specific location of the film layer can be adaptively adjusted according to actual needs.

[0147] Optional, Figure 36 yes Figure 1 The second cross-sectional diagram along the section line P-P', combined with Figure 1 、 Figure 24 and Figure 36 As shown, the auxiliary structure includes a light-transmitting hole LS.

[0148] Furthermore, the auxiliary structure may include a light-transmitting hole LS. The display panel is provided with a light-transmitting hole LS, and along the thickness direction of the display panel, the light-transmitting hole LS at least partially overlaps with the optical sensor 20, so that the display panel 10 can collect and judge external light. Specifically, the provision of the light-transmitting hole LS in the display panel 10 can ensure that light is incident on the optical sensor 20 through the light-transmitting hole LS, so as to ensure that the optical sensor 20 can perform information sensing based on the sensed optical information. For example, the optical sensor 20 can be a light sensor. In a plan view, the light sensor overlaps with the light-transmitting hole LS, and visible light can pass through the light-transmitting hole. Then, the light sensor can adjust the screen brightness of the display device according to the brightness of the surrounding light. In addition, the light sensor can also be an infrared light sensor, or a fingerprint recognition sensor. The fingerprint information or palm print information can be incident on the fingerprint recognition sensor through the light-transmitting hole, so that the processing chip in the display panel can perform corresponding operations based on the fingerprint information or palm print information sensed by the fingerprint sensor.

[0149] Further, combined Figure 1 、 Figure 24 and Figure 36 As shown, in order not to affect the normal light emission of the light emitting element 300, the light-transmitting hole LS can be set between the light emitting elements 300. Specifically, the orthographic projection of the light-transmitting hole LS onto the film layer where the anode connecting portion 400 is located is located at the second distance L2.

[0150] Figure 37 : is a schematic diagram of an orthographic projection of a light-transmitting hole and a signal line on a substrate provided by an embodiment of the present invention.

[0151] Specifically, refer to Figure 36 As shown, the display panel 10 further includes a light shielding layer 500, which is located on a side of the light emitting element 300 away from the pixel circuit 200. The light-transmitting hole LS in the display panel 10 is provided in the light shielding layer 500, facilitating the fingerprint recognition function or infrared sensing function of the display panel 10.

[0152] Furthermore, the signal line 600 in the display panel 10 is provided between the light shielding layer 600 and the substrate 100 for realizing signal transmission. Figure 38 and Figure 39 As shown, along the thickness of the display panel 10, the light-transmitting hole LS and the signal line 600 do not overlap. In other words, the signal line 600 avoids the light-transmitting hole LS when it is transmitted near the light-transmitting hole LS. This ensures that the signal line 600 does not block the light transmitted through the light-transmitting hole LS. It also prevents the signal line 600 from interfering with the light transmitted through the light-transmitting hole LS, such as causing diffraction. Therefore, by adjusting the signal line 600 near the light-transmitting hole LS, the light transmittance of the display panel 10 can be maintained.

[0153] Continue to refer Figures 36 to 38 As shown, the plurality of signal lines 600 include a plurality of first signal lines 610; the first signal line 610 includes a first main body portion 611 and a first winding portion 612 connected to each other, the orthographic projection of the first main body portion 611 on the plane where the substrate 100 is located is a first main body portion projection 611a, the orthographic projection of the first winding portion 612 on the plane where the substrate 100 is located is a first winding portion projection 612a, and the orthographic projection of the light-transmitting hole LS on the plane where the substrate 100 is located is a light-transmitting hole projection LSa; the first main body portion projection 611a extends along the first direction X2 and the straight line where the first main body portion projection 611a is located overlaps with the light-transmitting hole projection LSa; the first winding portion projection 612a overlaps with the light-transmitting hole projection LSa in the second direction X2; the second direction X2 intersects the first direction X1; there are two first winding portion projections of the first signal lines 610 located on opposite sides of the light-transmitting hole LS projection in the second direction X2;

[0154] And / or, the multiple signal lines 600 include multiple second signal lines 620; the second signal line 620 includes a connected second main body portion 621 and a second winding portion 622, the orthographic projection of the second main body portion 621 on the plane where the substrate 100 is located is the second main body portion projection 621a, the orthographic projection of the second winding portion 622 on the plane where the substrate 100 is located is the second winding portion projection 622a, and the orthographic projection of the light-transmitting hole LS on the plane where the substrate 100 is located is the light-transmitting hole projection LSa; the second main body portion projection 621a extends along the second direction X2 and the straight line where the second main body portion projection 621a is located overlaps with the light-transmitting hole projection LSa; the second winding portion projection 622a overlaps with the light-transmitting hole projection LSa in the first direction X1; there are two second signal lines 620 whose second winding portion projections 622a are located on two sides of the light-transmitting hole projection LSa that are relatively set in the first direction X1.

[0155] Specifically, refer to Figure 36 and Figure 37 As shown, the display panel 10 includes a plurality of first signal lines 610, each of which includes a first main portion 611 and a first winding portion 612. The orthographic projections of the first main portion 611 and the first winding portion 612 on the substrate 100 do not overlap with the orthographic projections of the light-transmitting hole LS on the substrate 100. The first main portion 611 extends along a first direction X1, and the first winding portion 612 is used to connect two adjacent first main portions 611. By avoiding the light-transmitting hole LS, the first signal lines 610 and the light-transmitting hole LS are arranged so as not to overlap along the thickness direction of the display panel 10.

[0156] Specific, combined Figure 37 As shown, the orthographic projection of the first main portion 611 on the plane of the substrate 100 is a first main portion projection 611a, the orthographic projection of the first winding portion 612 on the plane of the substrate 100 is a first winding portion projection 612a, and the orthographic projection of the light-transmitting hole LS on the plane of the substrate 100 is a light-transmitting hole projection LSa. The first main portion projection 611a extends along the first direction X1. Since the first main portion projection 611a overlaps with the light-transmitting hole projection LSa along the first direction X1, if the first signal line 610 is not provided with the first winding portion 612, the first main portion 611 will block the light-transmitting hole LS. Therefore, by setting the first winding portion 612, the first winding portion projection 612a overlaps with the light-transmitting hole projection LSa in the second direction X2. The first winding portion 612 is equivalent to avoiding the first signal line 610 from the light-transmitting hole LS, ensuring that the projection of the first signal line 610 on the substrate 100 does not overlap with the projection of the light-transmitting hole LS on the substrate 100, thereby ensuring the transmittance of the display panel 10.

The second main portion 621 extends along a second direction X2, and the second winding portion 622 is used to connect two adjacent second main portions 621. By avoiding the light-transmitting hole LS, the second signal lines 620 and the light-transmitting hole LS are arranged so as to not overlap along the thickness direction of the display panel 10.

[0158] Specific, combined Figure 38 As shown, the orthographic projection of the second main body portion 621 on the plane of the substrate 100 is a second main body portion projection 621a, the orthographic projection of the second winding portion 622 on the plane of the substrate 100 is a second winding portion projection 622a, and the orthographic projection of the light-transmitting hole LS on the plane of the substrate 100 is a light-transmitting hole projection LSa. The second main body portion projection 621a extends along the second direction X2. Since the second main body portion projection 621a overlaps with the light-transmitting hole projection LSa along the second direction X2, if the second signal line 620 is not provided with the second winding portion 622, the second main body portion 621 will block the light-transmitting hole LS. Therefore, by setting the second winding portion 622, the second winding portion projection 622a overlaps with the light-transmitting hole projection LSa in the first direction X1. The second winding portion 622 is equivalent to avoiding the second signal line 620 from the light-transmitting hole LS, ensuring that the projection of the second signal line 620 on the substrate 100 does not overlap with the projection of the light-transmitting hole LS on the substrate 100, thereby ensuring the transmittance of the display panel 10.

Specifically, the light emitting elements 300 include a first color light emitting element 300A, a second color light emitting element 300B, and a third color light emitting element 300C, thereby achieving a color display effect of the display panel 10 .

[0177] Furthermore, the reset signal line VREF may include a first reset signal line VREFa, a second reset signal line VREFb, and a third reset signal line VREFc.

Alternatively, at least two of the first, second, and third reset signal lines VREFa, VREFb, and VREFc can be placed in different layers. This increases the distance between the lines transmitting different reset signals and reduces interference between different reset signal lines VREF, thereby ensuring the stability and reliability of signal transmission within the display panel 10 and the overall display quality of the display panel 10. Placing different reset signal lines VREF in different film layer locations also increases the flexibility of wiring within the film layer, reduces the difficulty of wiring within the film layer, and reduces the manufacturing cost of the display panel 10.
