[0033] In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are some, but not all, of the embodiments of the present disclosure. Based on the described embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of protection of the present disclosure.

[0034] Unless otherwise defined, technical terms or scientific terms used in the present disclosure should be understood as having the same meaning as commonly understood by one of ordinary skill in the art to which the present disclosure belongs. The terms “first”, “second” and similar terms used in the present disclosure do not denote any order, quantity or importance, but are used to distinguish different components. Similarly, the terms “include” or “contain” and similar terms mean that the elements or objects before the terms encompass the elements or objects listed after the terms and their equivalents, without excluding other elements or objects. The terms “connect” or “connected” and similar terms are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. The terms “up”, “down”, “left”, “right” and the like are only used to represent relative positional relationships, and when the absolute positions of the described objects change, the relative positional relationships may also change accordingly.

[0035] With the development of display technology, the conventional notch screen or water drop screen design gradually cannot meet the user's demand for high screen-to-body ratio of the display panel, and a series of display panels with a light-transmitting display area have emerged as the times require. In such display panels, a hardware such as a photosensitive sensor (e.g., a camera) can be arranged in the light-transmitting display area, and since no hole needs to be punched, it is possible to realize a true full-screen display while ensuring the practicability of the display panel.

[0036] In the related art, a display panel with an under-screen camera generally includes a first display area for normal display and a second display area for setting a camera. The second display area generally includes a plurality of light emitting elements and a plurality of pixel circuits, each pixel circuit is connected with a light emitting element and is used to drive the light emitting element to emit light, and the pixel circuits and the light emitting elements connected with each other overlap in a direction perpendicular to the display panel.

[0037] In the research, the inventors found that in the general under-screen camera technology, the second display area for setting the camera is generally globally displayed. Although some researches have adopted technical solutions to make the pixel density in the second display area lower than the pixel density in the first display area for normal display, the transmittance of the second display area is still greatly reduced, the photographing effect of the camera is affected, and the display effect of the second display area and the display effect of the first display area have a relatively obvious brightness contrast, and the aesthetic coordination is poor.

[0038] At least one embodiment of the present disclosure provides a display panel, which includes a first display area and a second display area, the first display area includes a plurality of first sub-pixels; the second display area includes at least one display sub-area and at least one light-transmitting area, the display sub-area includes a plurality of second sub-pixels, the light-transmitting area is configured to transmit light, and at least one of the display sub-area and the light-transmitting area is an independent area with a set shape.

[0039] Embodiments of the present disclosure can effectively improve the light transmittance of the second display area, improve the photosensitive effect of the under-screen photosensitive sensor, and cooperate the display effect of the display sub-area with the display effect of the first display area, which is conducive to making the overall display effect of the display panel more coordinated.

[0040] The display panel and the display device will be described below in conjunction with the accompanying drawings and some embodiments.

[0041] Reference Figure 1 The display panel 01 can include a substrate BS. The display panel 01 includes a first display area A1 and a second display area A2, and the first display area A1 can be located at least one side of the second display area A2. For example, in some embodiments, the first display area A1 surrounds the second display area A2. That is, the second display area A2 can be surrounded by the first display area A1. For example, the second display area A2 can be located at the top center position of the substrate BS. For example, a sensor (such as a camera) and the like hardware is arranged in the second display area A2 of the display panel. For example, the second display area A2 can be a light-transmitting display area, and the first display area A1 is a display area.

[0042] For example, the sensor includes an infrared sensor, an ultrasonic sensor, a LIDAR (Light Detection and Ranging) sensor, a radar sensor, a camera, a distance sensor, but is not limited thereto.

[0043] Figure 1 The display panel 01 shown in the figure is circular in the area where the second display area A2 is located, and the second display area A2 is located in the upper middle part of the display panel 01, but is not limited thereto.

[0044] Reference Figure 1 The first display area A1 includes a plurality of first sub-pixels 10, so that the first display area A1 serves as a display area. For example, the first display area A1 is opaque and is used only for display. The second display area A2 includes at least one display sub-area A21 and at least one light-transmissive area A22. The display sub-area A21 includes a plurality of second sub-pixels 20, and the light-transmissive area A22 is configured to transmit light. For example, the display sub-area A21 can serve as a display area of the second display area A2 and be disposed in cooperation with the light-transmissive area A22, so that the second display area A2 can serve as a light-transmissive display area, the light transmittance is effectively improved, the photosensitive effect of the under-screen photosensitive sensor is improved, and in the case where the photosensitive sensor is a camera, the camera shooting effect is improved.

[0045] Reference Figure 1 In the second display area A2, at least one of the display sub-area A21 and the light-transmissive area A22 is an independent area with a set shape. Thus, the second display area A2 can display in the area with the set shape or transmit light in the area with the set shape. The display effect of the display sub-area A21 can cooperate with the display effect of the first display area A1, which is conducive to making the overall display effect of the display panel more coordinated and aesthetically pleasing.

[0046] In some embodiments, the display sub-area A21 can achieve an integrated display effect.

[0047] For example, referring to Figure 1 In the display panel 01, by cooperating the display effect of the display sub-area A21 with the display effect of the first display area A1, an integrated display effect can be achieved, and the difference in brightness between the display sub-area A21 and the first display area A1 can be visually weakened, so that the overall display effect of the display panel 01 tends to be diversified and harmonized. Thus, the display performance and the light-transmissive performance of the second display area A2 can be taken into account and balanced, so that the second display area A2 has good display function and good light-transmissive effect at the same time, and the user has a better use experience.

[0048] For clarity, Figure 1The first display area A1 does not show all the first sub-pixels 10, the display sub-area A21 also does not show all the second sub-pixels 20, and the light-transmitting area A22 is not provided with sub-pixels. For example, the pixel density of the plurality of first sub-pixels 10 in the first display area A1 and the pixel density of the plurality of second sub-pixels 20 in the display sub-area A21 are both illustrative, and can be set according to design requirements. For example, the first display area A1 is a continuous display area, the display sub-area A21 is a continuous display area, and the light-transmitting area A22 is a continuous light-transmitting area. For example, the light-transmitting area A22 is not provided with pixel circuits and light-emitting elements. In some embodiments, the light-transmitting area can be a non-light-emitting black area visible to the human eye.

[0049] Figure 2 A partial schematic view of a display panel provided by some embodiments of the present disclosure.

[0050] For example, referring to Figure 2 , the plurality of first sub-pixels 10 are arranged in the first display area A1 with intervals, the plurality of second sub-pixels 20 are arranged in the display sub-area A21 with intervals, and the arrangement manner of the plurality of first sub-pixels 10 is the same as that of the plurality of second sub-pixels 20, but embodiments of the present disclosure are not limited thereto. For example, each first sub-pixel 10 or each second sub-pixel 20 includes a pixel circuit and a light-emitting element, and the pixel circuit is configured to drive the light-emitting element. For example, the pixel circuit is configured to provide a driving current to drive the light-emitting element to emit light. For example, the light-emitting element is an organic light-emitting diode (OLED) or a micro light-emitting diode (Micro LED) or a quantum dot light-emitting diode (QLED), and the light-emitting element emits red light, green light, blue light, or white light, etc. under the driving of its corresponding pixel circuit.

[0051] For example, referring to Figure 2 , the plurality of first sub-pixels 10 include a plurality of first-type sub-pixels 010, a plurality of second-type sub-pixels 020, and a plurality of third-type sub-pixels 030, each type of sub-pixel is configured to emit light of a different color, such as red, green, and blue. For example, one of the first-type sub-pixels 010 and the second-type sub-pixels 020 is a blue sub-pixel emitting blue light, and the other is a red sub-pixel emitting red light, and the third-type sub-pixel 030 is a green sub-pixel emitting green light. For example, the first-type sub-pixel 010 is a blue sub-pixel, and the second-type sub-pixel 020 is a red sub-pixel, and the area of the light-emitting region of the blue sub-pixel is greater than that of the red sub-pixel. For example, the area of the light-emitting region of the blue sub-pixel is greater than that of the green sub-pixel. Of course, embodiments of the present disclosure are not limited thereto, for example, the first-type sub-pixel can be a green sub-pixel, the second-type sub-pixel can be a blue sub-pixel, and the third-type sub-pixel can be a red sub-pixel; or the first-type sub-pixel can be a blue sub-pixel, the second-type sub-pixel can be a red sub-pixel, and the third-type sub-pixel can be a green sub-pixel, etc.

[0052] For example, referring to Figure 2 , the plurality of first type sub-pixels 010 and the plurality of second type sub-pixels 020 are arranged alternately along the first direction N and the second direction Y to form a plurality of first pixel rows 011 and a plurality of first pixel columns 012, and the plurality of third type sub-pixels 030 are arranged in an array along the first direction N and the second direction Y to form a plurality of second pixel rows 021 and a plurality of second pixel columns 022. The plurality of first pixel rows 011 and the plurality of second pixel rows 021 are arranged alternately along the first direction N, and the first sub-pixels 10 in the first pixel rows 011 and the second pixel rows 021 are staggered with each other along the second direction Y. The plurality of first pixel columns 012 and the plurality of second pixel columns 022 are arranged alternately along the second direction Y, and the first sub-pixels 10 in the first pixel columns 012 and the second pixel columns 022 are staggered with each other along the first direction N. The first direction N and the second direction Y intersect each other. For example, the first direction N and the second direction Y can be perpendicular to each other.

[0053] For example, referring to Figure 2 , one second pixel row 021 includes a plurality of sub-pixel pairs arranged along the second direction Y, two third type sub-pixels 030 in one sub-pixel pair are a first pixel block 0301 and a second pixel block 0302 respectively, and the first pixel block 0301 and the second pixel block 0302 are arranged alternately along the second direction Y. For example, the first pixel block 0301 and the second pixel block 0302 in one second pixel column 022 are arranged alternately along the first direction N.

[0054] For example, referring to Figure 2 , at least two second pixel rows 021 include a plurality of third sub-pixel pairs arranged along the first direction N, two third type sub-pixels 030 in at least two third sub-pixel pairs are a first pixel block 0301 and a second pixel block 0302 respectively, and the first pixel block 0301 and the second pixel block 0302 are arranged alternately along the second direction Y. For example, the first pixel block 0301 and the second pixel block 0302 in at least two second pixel columns 022 are arranged alternately along the first direction N.

[0055] For example, referring to Figure 2 , the plurality of first sub-pixels 10 include a plurality of first pixel groups 200, one first pixel group 200 includes one first type sub-pixel 010, one first pixel block 0301, one second pixel block 0302 and one second type sub-pixel 020. For example, at least two first pixel groups 200 include one first type sub-pixel 010, one first pixel block 0301, one second pixel block 0302 and one second type sub-pixel 020. For example, each first pixel group 200 includes two rows and four columns of first sub-pixels 10.

[0056] For example, referring to Figure 2For example, in the first pixel group 200, the first pixel block 0301 and the first type sub-pixel 010 form a first pixel unit 201, and the second pixel block 0302 and the second type sub-pixel 020 form a second pixel unit 202. For example, in at least two first pixel groups 200, the first pixel block 0301 and the first type sub-pixel 010 form a first pixel unit 201, and the second pixel block 0302 and the second type sub-pixel 020 form a second pixel unit 202.

[0057] It should be noted that the first pixel unit and the second pixel unit described above are not strictly pixels, i.e., a pixel defined by a complete first type sub-pixel 010, a second type sub-pixel 020, and a third type sub-pixel 030. Here, the first pixel group 200 refers to a pixel arrangement structure that can include multiple repeatedly arranged first pixel groups.

[0058] For example, referring to Figure 2 The first type sub-pixel 010 and the second type sub-pixel 020 are common sub-pixels, and through a sub-pixel rendering algorithm, the four sub-pixels can realize the display of two pixel units.

[0059] For example, Figure 2 A second pixel group G2 located in the display sub-area A21 is also shown.

[0060] For example, referring to Figure 2 The plurality of second sub-pixels 20 include a plurality of first type sub-pixels G10, a plurality of second type sub-pixels G20, and a plurality of third type sub-pixels G30. For example, one of the first type sub-pixel G10 and the second type sub-pixel G20 is a blue sub-pixel emitting blue light, the other of the first type sub-pixel G10 and the second type sub-pixel G20 is a red sub-pixel emitting red light, and the third type sub-pixel G30 is a green sub-pixel emitting green light. For example, the first type sub-pixel G10 is a blue sub-pixel, the second type sub-pixel G20 is a red sub-pixel, and the area of the light emitting region of the blue sub-pixel is greater than the area of the light emitting region of the red sub-pixel.

[0061] For example, referring to Figure 2 The two third type sub-pixels G30 in a sub-pixel pair are respectively a first pixel block G31 and a second pixel block G32.

[0062] For example, referring to Figure 2For example, the plurality of second sub-pixels 20 comprises a plurality of second pixel groups G2, one second pixel group G2 comprises one first type sub-pixel G10, one first pixel block G31, one second pixel block G32 and one second type sub-pixel G20. For example, at least two second pixel groups G2 comprises one first type sub-pixel G10, one first pixel block G31, one second pixel block G32 and one second type sub-pixel G20.

[0063] For example, referring to Figure 2 In one second pixel group G2, the first pixel block G31 and the first type sub-pixel G10 form a first pixel unit G21, and the second pixel block G32 and the second type sub-pixel G20 form a second pixel unit G22. For example, in at least two second pixel groups G2, the first pixel block G31 and the first type sub-pixel G10 form a first pixel unit G21, and the second pixel block G32 and the second type sub-pixel G20 form a second pixel unit G22.

[0064] For example, the second pixel group G2 and the first pixel group 200 are the same in structure, that is, the number of sub-pixels included is the same.

[0065] It should be noted that the pixel arrangement form provided in the embodiments of the present disclosure is only exemplary and is not limited. In some embodiments of the present disclosure, the pixel arrangement form can be flexibly changed according to the actual layout design needs. For example, "diamond arrangement", "diamond-like arrangement", "GGRB arrangement" and the like, which are not limited by the embodiments of the present disclosure.

[0066] For example, referring to Figure 2 The display sub-area A21 is circular, that is, the plurality of second sub-pixels 20 are arranged in the circular area. At least part of the light transmission area A22 is located between the display sub-area A21 and the first display area A1, and the light transmission area A22 surrounds the display sub-area A21, but is not limited thereto. Therefore, the display sub-area A21 and the light transmission area A22 are arranged as two independent areas, so that the area for display and the area for light transmission in the second display area A2 are separated, so as to improve the light transmission rate of the second display area A2. At the same time, the circular display sub-area A21 and the first display area A1 can cooperate together to make the display effect of the whole display substrate 01 more coordinated and aesthetic.

[0067] For example, referring to Figure 2 The display sub-area A21 is a continuous and whole display area, and the light transmission area A22 is a continuous and whole light transmission area. For example, referring to Figure 2 The display sub-area A21 and the light transmission area A22 are arranged in blocks.

[0068] For example, referring to Figure 2 The display sub-area A21 is a continuous display area and is not separated by the light transmission area A22. For example, referring toFigure 2 The light-transmitting region A22 is a continuous light-transmitting region and is not divided by the display sub-region A21.

[0069] With reference to Figure 2 The maximum dimension of the light-transmitting region A22 in the first direction N is greater than the maximum dimension of the display sub-region A21 in the first direction N. With reference to Figure 2 The maximum dimension of the light-transmitting region A22 in the second direction Y is greater than the maximum dimension of the display sub-region A21 in the second direction Y.

[0070] With reference to Figure 2 The maximum dimension of the light-transmitting region A22 in the first direction N is equal to the maximum dimension of the second display region A2 in the first direction N, and the maximum dimension of the light-transmitting region A22 in the second direction Y is equal to the maximum dimension of the second display region A2 in the second direction Y.

[0071] With reference to Figure 2 The light-transmitting region A22 is continuous and surrounds the display sub-region A21.

[0072] With reference to Figure 2 The maximum dimension of the light-transmitting region A22 in the first direction N is greater than 20 times the maximum dimension of the second pixel group G2 in the first direction N within the display sub-region A21, i.e., greater than the maximum dimension of 20 rows of second pixel groups G2 in the first direction N. The maximum dimension of the light-transmitting region A22 in the second direction Y is greater than 20 times the maximum dimension of the second pixel group G2 in the second direction Y within the display sub-region A21, i.e., greater than the maximum dimension of 20 columns of second pixel groups G2 in the first direction N.

[0073] For example, with reference to Figure 2 The light-emitting elements of the plurality of second sub-pixels 20 in the display sub-region A21 can emit light at the same time and cause the display sub-region A21 to present a fixed image, but the present disclosure is not limited thereto. For example, the light-emitting elements of the plurality of second sub-pixels 20 can also emit light at different times, and the image presented by the display sub-region A21 can constantly change under the control of the control element, and the embodiments of the present disclosure do not limit this.

[0074] For example, with reference to Figure 2 The set shape of the display sub-region A21 or the light-transmitting region A22 can include at least one of a character, a figure, a letter, a number, but the present disclosure is not limited thereto. For example, the above-mentioned character can include a part of a character, or include a combination of a plurality of characters, and the embodiments of the present disclosure do not limit this. For example, the above-mentioned figure can include at least one of a triangle, a circle, an ellipse, a polygon, a heart shape, a pentagram, a ring, but the present disclosure is not limited thereto. For example, the above-mentioned figure can also include a figure in an irregular shape, for example, can include a figure of a logo with a specific meaning, and the specific can be set according to design requirements.

[0075] For example, referring to Figure 2 The area of the display sub-area A21 may be 5% to 30% of the area of the second display area A2, but is not limited thereto. For example, when the display sub-area A21 includes multiple portions, the area of the display sub-area A21 is the sum of the areas of the multiple portions. In this way, the area of the light-transmissive area A21 in the second display area A2 is relatively large, thereby improving the light transmittance of the second display area A2.

[0076] For example, referring to Figure 2 In some embodiments of the present disclosure, the area of the display sub-area A21 may be 10% to 25% of the area of the second display area A2. For example, the area of the display sub-area A21 may be 15% to 30% of the area of the second display area A2. For example, the area of the display sub-area A21 may be 20% to 28% of the area of the second display area A2, which is not limited in the embodiments of the present disclosure.

[0077] For example, referring to Figure 2 In the display panel 01, the area of the display sub-area A21 may be 5% to 15% of the area of the second display area A2, so as to further improve the transmittance of the second display area A2. For example, the area of the display sub-area A21 may be 5% to 10% of the area of the second display area A2. For example, the area of the display sub-area A21 may be 3% to 8% of the area of the second display area A2, but is not limited thereto.

[0078] For example, referring to Figure 2 In the display panel 01, the ratio of the area of the display sub-area A21 to the area of the light-transmissive area A22 may be 0.3 to 0.7, so as to improve the light transmittance of the second display area A2 while having a suitable ratio between the area of the display sub-area A21 and the area of the light-transmissive area A22, so as to make the second display area A2 have good display effect, and balance the light transmission and display of the second display area A2. For example, the ratio of the area of the display sub-area A21 to the area of the light-transmissive area A22 may be 0.35 to 0.65. For example, the ratio of the area of the display sub-area A21 to the area of the light-transmissive area A22 may be 0.45 to 0.55. The embodiments of the present disclosure are not limited thereto.

[0079] For example, referring to Figure 2 In the display panel 01, the area with the set shape in the second display area A2 is configured to be recognized by the human eye, so as to make the set shape easy to identify and enhance the coordination between the second display area A2 and the first display area A1.

[0080] For example, referring to Figure 3The display sub-area A21 or the light-transmitting area A21 in the second display area A2 can have a set shape that is easy to identify, such as at least one of a character, a figure, a letter, a number, and the like, without any limitation in the embodiments of the present disclosure.

[0081] Figure 3 For example, the area of the corresponding sub-pixel in the second pixel group G2 is smaller than the area of the corresponding sub-pixel in the first pixel group 200, but the embodiments of the present disclosure are not limited thereto.

[0082] Figure 3 Another partial schematic view of a display panel provided by some embodiments of the present disclosure.

[0083] For example, referring to Figure 4 In the display panel 02, the display sub-area A21 in the second display area A2 includes a first display sub-part A211, a second display sub-part A212, a third display sub-part A213, a fourth display sub-part A214, and a fifth display sub-part A215. The area where the first display sub-part A211 is located is circular and is located in the middle of the second display area A2, for example, the center of the first display sub-part A211 can coincide with the center of the second display area A2, but is not limited thereto. For example, the area where the second display sub-part A212, the third display sub-part A213, the fourth display sub-part A214, and the fifth display sub-part A215 are located is larger than the area where the first display sub-part A211 is located. For example, the second display sub-part A212, the third display sub-part A213, the fourth display sub-part A214, and the fifth display sub-part A215 are all elliptical and are arranged around the first display sub-part A211 and are arranged two by two. For example, the line connecting the centers of symmetry (for example, the centers of gravity) of the second display sub-part A212 and the fourth display sub-part A214 coincides with or approximately coincides with the center of the first display sub-part A211. For example, the line connecting the centers of symmetry of the third display sub-part A213 and the fifth display sub-part A215 coincides with or approximately coincides with the center of the first display sub-part A211.

[0084] In this way, the distribution of the plurality of display sub-areas A21 in the second display area A2 has good symmetry, and the coordination and aesthetic appearance of the second display area A2 and the first display area A1 when they are displayed together are improved.

[0085] For example, referring to Figure 4In the display panel 02, the second display area A2 can include N display sub-areas A21, and N is a positive integer less than or equal to 10. For example, the area of the second display area A2 can be much smaller than the area of the first display area A1, and thus, in order to make the N display sub-areas A21 in the second display area A2 have good display effects and be easy to identify, the number of the display sub-areas A21 can be small. For example, the number N of the display sub-areas A21 can be at least one of 2, 3, 4, and 5, but is not limited thereto.

[0086] Figure 2 Another partial schematic view of a display panel provided by some embodiments of the present disclosure.

[0087] For example, referring to Figure 4 , compared with the display panel 01 shown in Figure 4 , the second display area A2 in the display panel 03 can include a plurality of light-transmitting areas A22, and the remaining structures are the same as or similar to those of the display panel 01.

[0088] For example, referring to Figure 5 , in the display panel provided by at least one embodiment of the present disclosure, the number of the light-transmitting areas A22 in the second display area A2 is M, and M is a positive integer less than or equal to 10. The display panel 03 is described by taking an example of three light-transmitting areas A22, but is not limited thereto. For example, the area of the second display area A2 can be much smaller than the area of the first display area A1, and thus, in order to make the M light-transmitting areas A22 in the second display area A2 easy to identify, the number of the light-transmitting areas A22 can be small. For example, the number M of the light-transmitting areas A22 can be at least one of 2, 3, 4, and 5, but is not limited thereto.

[0089] For example, referring to Figure 5 , the shapes of the at least two light-transmitting areas A22 in the second display area A2 are different. For example, in the display panel 03, the second display area A2 includes a first light-transmitting sub-area A221, a second light-transmitting sub-area A222, and a third light-transmitting sub-area A223, the area where the third light-transmitting sub-area A223 is located is in the shape of “U”, the areas where the first light-transmitting sub-area A221 and the second light-transmitting sub-area A222 are located are both in the shape of a circle, and the first light-transmitting sub-area A221 and the second light-transmitting sub-area A222 are respectively arranged in the area surrounded by the third light-transmitting sub-area A223. For example, the area of the first light-transmitting sub-area A221 can be equal to or approximately equal to the area of the second light-transmitting sub-area A222, but is not limited thereto. For example, the shapes and positions of the first light-transmitting sub-area A221, the second light-transmitting sub-area A222, and the third light-transmitting sub-area A223 can be set according to design requirements, so that the light-transmitting property of the second display area A2 in the set area is good, and embodiments of the present disclosure are not limited in this regard.

[0090] Figure 2FIG. 6 is a partial schematic view of a display panel according to some embodiments of the present disclosure.

[0091] For example, referring to FIG. 6, the second display area A2 in the display panel 04 is different from the second display area in the display panel 01, and the rest of the structures are the same as or similar to the display panel 01. Figure 5 Figure 5 For example, referring to FIG. 6, the second display area A2 in the display panel 04 is different from the second display area in the display panel 01, and the rest of the structures are the same as or similar to the display panel 01.

[0092] For example, referring to FIG. 6, the second display area A2 in the display panel 04 is different from the second display area in the display panel 01, and the rest of the structures are the same as or similar to the display panel 01. Figure 6 For example, referring to FIG. 6, the second display area A2 in the display panel 04 is different from the second display area in the display panel 01, and the rest of the structures are the same as or similar to the display panel 01.

[0093] For example, referring to FIG. 6, the second display area A2 in the display panel 04 is different from the second display area in the display panel 01, and the rest of the structures are the same as or similar to the display panel 01. Figure 6 For example, referring to FIG. 6, the second display area A2 in the display panel 04 is different from the second display area in the display panel 01, and the rest of the structures are the same as or similar to the display panel 01.

[0094] For example, referring to FIG. 6, the second display area A2 in the display panel 04 is different from the second display area in the display panel 01, and the rest of the structures are the same as or similar to the display panel 01.

[0095] Figure 5 FIG. 7 is a partial schematic view of a display panel according to some embodiments of the present disclosure.

[0096] For example, referring to FIG. 7, the second display area A2 in the display panel 05 is different from the second display area in the display panel 04, and the rest of the structures are the same as or similar to the display panel 04. Figure 6 Figure 6 For example, referring to FIG. 7, the second display area A2 in the display panel 05 is different from the second display area in the display panel 04, and the rest of the structures are the same as or similar to the display panel 04.

[0097] For example, referring to FIG. 7, the second display area A2 in the display panel 05 is different from the second display area in the display panel 04, and the rest of the structures are the same as or similar to the display panel 04.​​Figure 7 The display panel 05 further includes a second display sub-area A2 102, a region where a second light-transmissive area A2 202 is located is annular, and the second light-transmissive area A2 202 is located between the first display sub-area A2 101 and the second display sub-area A2 102. The second display sub-area A2 102 is located in a region surrounded by an inner boundary of the second light-transmissive area A2 202. Thus, in a direction in which a boundary of the second display area A2 points to a center of the second display area A2, the first light-transmissive area A2 201, the first display sub-area A2 101, the second light-transmissive area A2 202, and the second display sub-area A2 102 are sequentially arranged, and the region where the second display sub-area A2 102 is located has the smallest area and is located in a middle portion of the second display area A2. For example, a center of the second display sub-area A2 102 can coincide with or substantially coincide with a center of the second display area A2.

[0098] In this way, the plurality of display sub-areas A2 1 and the plurality of light-transmissive areas A2 2 located in the second display area A2 can be alternately arranged, so that the regions for display and the regions for light transmission of the second display area A2 are uniformly distributed, to present a more coordinated display effect.

[0099] It should be noted that the embodiments of the present disclosure do not limit the number of the display sub-areas A2 1 and the light-transmissive areas A2 2 alternately arranged in the second display area A2. For example, referring to FIG. 2, the display panel 01 includes a plurality of display sub-areas A2 1 and a plurality of light-transmissive areas A2 2 alternately arranged in the second display area A2. Figure 7 The light-transmissive area can also be arranged inside the second display sub-area A2 102 to meet different design requirements. For example, the shapes of the display sub-areas A2 1 and the light-transmissive areas A2 2 alternately arranged in the second display area A2 can be different, and the embodiments of the present disclosure do not limit this.

[0100] Figure 2 FIG. 6 is a partial schematic view of yet another display panel provided by some embodiments of the present disclosure.

[0101] For example, referring to FIG. 6, the display panel 06 includes a third display sub-area A2 103, a fourth display sub-area A2 104, and a third light-transmissive area A2 203. The third light-transmissive area A2 203 is annular, and the third light-transmissive area A2 203 is located between the third display sub-area A2 103 and the fourth display sub-area A2 104. The third display sub-area A2 103 is located between an outer boundary of the third light-transmissive area A2 203 and a boundary of the second display area A2, and the fourth display sub-area A2 104 is located in a region surrounded by an inner boundary of the third light-transmissive area A2 203. Figure 7 The second display area A2 of the display panel 06 is different from the second display area in the display panel 01, and the remaining structures are the same as or similar to those of the display panel 01. Figure 7

[0102] For example, referring to FIG. 6, the display panel 06 includes a third display sub-area A2 103, a fourth display sub-area A2 104, and a third light-transmissive area A2 203. The third light-transmissive area A2 203 is annular, and the third light-transmissive area A2 203 is located between the third display sub-area A2 103 and the fourth display sub-area A2 104. The third display sub-area A2 103 is located between an outer boundary of the third light-transmissive area A2 203 and a boundary of the second display area A2, and the fourth display sub-area A2 104 is located in a region surrounded by an inner boundary of the third light-transmissive area A2 203. Figure 8

[0103] ​​For example, referring to Figure 8 In the display panel 06, the outer boundary and the inner boundary of the third light-transmitting region A2203 are both rectangular, and the center of the outer boundary of the third light-transmitting region A2203 substantially coincides with the center of the inner boundary of the third light-transmitting region A2203. The area of the region surrounded by the outer boundary of the third light-transmitting region A2203 is 3-6 times the area of the region where the fourth display sub-region A2104 is located, but is not limited thereto. For example, in some embodiments of the present disclosure, a portion of the inner boundary of the third display sub-region A2103 can coincide with a portion of the outer boundary of the fourth display sub-region A2104. For example, the inner boundary of the third display sub-region A2103 can be arranged in a spaced manner with the outer boundary of the fourth display sub-region A2104, and a portion of the inner boundary of the third display sub-region A2103 can be parallel to a portion of the outer boundary of the fourth display sub-region A2104, but is not limited thereto.

[0104] In this way, the central part and the region near the edge of the second display region A2 can be displayed, the region where the third light-transmitting region A2203 for light transmission is located is annular, and the second display region A2 can have a more coordinated display effect.

[0105] Figure 7 Another partial schematic view of a display panel is provided for some embodiments of the present disclosure.

[0106] For example, referring to Figure 8 The second display region A2 in the display panel 07 is different from the second display region in Figure 8 , and the remaining structures are the same as or similar to those of the display panel 06.

[0107] For example, referring to Figure 9 The display panel 07 further includes a fourth light-transmitting region A2204, the region where the fourth display sub-region A2104 is located is annular, the fourth display sub-region A2104 is located between the third light-transmitting region A2203 and the fourth light-transmitting region A2204, and the fourth light-transmitting region A2204 is located within the region surrounded by the inner boundary of the fourth display sub-region A2104. Thus, in the direction in which the boundary of the second display region A2 points to the center of the second display region A2, the third display sub-region A2103, the third light-transmitting region A2203, the fourth display sub-region A2104, and the fourth light-transmitting region A2204 are arranged in sequence, the area of the region where the fourth display sub-region A2104 is located is the smallest, and the fourth display sub-region A2104 is located in the central part of the second display region A2. For example, the center of the fourth display sub-region A2104 can coincide with or substantially coincide with the center of the second display region A2.

[0108] This arrangement allows multiple display sub-areas A21 and multiple light-transmitting areas A22 located in the second display area A2 to be arranged alternately, thereby making the area used for display and the area used for light transmission in the second display area A2 evenly distributed, so as to present a more harmonious display effect.

[0109] For example, refer to Figure 9 In some embodiments of this disclosure, a display sub-area may also be provided inside the fourth light-transmitting area A2204 to meet different design requirements. For example, the positions of the alternately arranged display sub-areas A21 and light-transmitting area A22 in the second display area A2 can be set according to design requirements, and the embodiments of this disclosure do not limit this.

[0110] Figure 5 This is a partial schematic diagram of yet another display panel provided for some embodiments of the present disclosure.

[0111] For example, refer to Figure 9 The second display area A2 in display panel 08 and Figure 9 Unlike the second display area in the previous one, the display panel 08 includes a first light-transmitting area A2201, multiple second light-transmitting areas A2202 and multiple first display sub-areas A2105, and the rest of the structure is the same as or similar to that of the display panel 04.

[0112] For example, refer to Figure 9 The display panel 08 includes a second light-transmitting area A2202-1, a second light-transmitting area A2202-2, a second light-transmitting area A2202-3, a first display sub-area A2105-1, and a first display sub-area A2105-2. The first light-transmitting area A2201 is located between the outer boundary of each first display sub-area A2105 and the boundary of the second display area A2. That is, the first light-transmitting area A2201 is located between the outer boundary of the first display sub-area A2105-1 and the boundary of the second display area A2, and the first light-transmitting area A2201 is located between the outer boundary of the first display sub-area A2105-2 and the boundary of the second display area A2. Each first display sub-region may have at least one second light-transmitting region A2202 inside. For example, the first display sub-region A2105-1 may have a second light-transmitting region A2202-1 and a second light-transmitting region A2202-2 inside, and the first display sub-region A2105-2 may have a second light-transmitting region A2202-3 inside. The embodiments of this disclosure are not limited thereto. For example, when the first display sub-region A2105 has multiple second light-transmitting regions A2202 inside, the inner boundary of the first display sub-region A2105 may include multiple portions corresponding to the multiple second light-transmitting regions A2202. That is, each of the multiple second light-transmitting regions A2202 is located within the area enclosed by a portion of the inner boundary of the first display sub-region A2105.

[0113] For example, refer toFigure 9 The area surrounded by the outer boundary of the first display sub-area A2 105-1 is circular, and the area surrounded by the outer boundary of the first display sub-area A2 105-2 is rectangular. The second light-transmitting area A2 202-1, the second light-transmitting area A2 202-2, and the second light-transmitting area A2 202-3 are all rectangular, and the area of the region where the second light-transmitting area A2 202-1 is located and the area of the region where the second light-transmitting area A2 202-2 is located are substantially equal, and both are smaller than the area of the region where the second light-transmitting area A2 202-3 is located. Embodiments of the present disclosure are not limited thereto.

[0114] In this way, a plurality of first display areas A2 105 can be arranged in the second display area A2, and one or more second light-transmitting areas A2 202 with a reasonable number, shape, and area can be arranged in different first display areas A2 105, so that the second display area A2 can display or transmit light in the set area, thereby better meeting the design and application requirements.

[0115] For example, referring to Figure 10 In the display panel 08, the number of second light-transmitting areas A2 202 in the second display area A2 can be K, and K is a positive integer less than or equal to 5. For example, the number K of second light-transmitting areas A2 202 can be at least one of 2, 3, 4, and 5, but is not limited thereto, so that the second display area A2 has a good light transmission rate.

[0116] For example, referring to Figure 10 In the display panel 08, the number of second light-transmitting areas A2 202 in the same display sub-area A2 can be L, and L is a positive integer less than or equal to 5. For example, the number K of second light-transmitting areas A2 202 in the same display sub-area A2 can be 2 or 3, but is not limited thereto, so that the second display area A2 has a good light transmission rate while also having a good display effect.

[0117] Figure 9 Another partial schematic view of a display panel is provided for some embodiments of the present disclosure.

[0118] For example, referring to Figure 10 The shapes of the first light-transmitting area A2 201, the plurality of second light-transmitting areas A2 202, and the plurality of first display sub-areas A2 105 in the display panel 09 are deformed compared with the second display area 08 in Figure 10 The rest of the structures are the same as or similar to the display panel 08, and the same parts will not be repeated.

[0119] For example, referring to Figure 10The outer boundary of the first display sub-area A2 105-1 is in a "wavy shape", the area where the second light-transmitting area A2 202-1 is located and the area where the second light-transmitting area A2 202-3 is located are both in a circular shape, and the area where the second light-transmitting area A2 202-2 is located is in a rectangular shape. Thus, the shape of the first display sub-area A2 105-1 in the second display area A2 is different from the shape of the first display sub-area A2 105-2. Meanwhile, in the first display sub-area A2 105-1, the shape of the area where the second light-transmitting area A2 202-1 is located is also different from the shape of the area where the second light-transmitting area A2 202-3 is located, but embodiments of the present disclosure are not limited thereto.

[0120] For example, referring to Figure 2 The number of the first display sub-areas A2 105 in the second display area A2 can be greater than 2, and the shape of each first display sub-area A2 105 can be different. For example, the number of the second light-transmitting areas A2 202 arranged in the same first display sub-area A2 105 can also be greater than 2, and the shapes of the plurality of second light-transmitting areas A2 202 can also be different, which can be set according to design requirements.

[0121] For example, referring to Figure 3 The second light-transmitting area A2 202 and the second light-transmitting area A2 202-3 are respectively located in different first display sub-areas A2 105 and respectively include different shapes. For example, the number of the first display sub-areas A2 105 arranged in the second display area A2 can be greater than 2, at least one second light-transmitting area A2 202 is arranged in each first display sub-area A2 105, and the shape of the second light-transmitting area A2 202 in each first display sub-area A2 105 can be different from the shape of the second light-transmitting area A2 202 in other first display sub-areas A2 105, but embodiments of the present disclosure are not limited thereto.

[0122] By flexibly arranging a plurality of first display sub-areas A2 105 and a plurality of second light-transmitting areas A2 202 in different forms, design requirements can be better met.

[0123] For example, in some embodiments of the present disclosure, referring to Figure 3 The arrangement of the plurality of first sub-pixels 10 in the first display area A1 is the same as the arrangement of the plurality of second sub-pixels 20 in the second display area A2, and the density of the plurality of first sub-pixels 10 in the first display area A1 is the same as the density of the plurality of second sub-pixels 20 in the second display area A2. Thus, at least part of the shape and at least part of the density of the mask plate used when manufacturing the first display area A1 and the second display area A2 are consistent, thereby simplifying the manufacturing process of the display panel 01 and reducing the manufacturing cost.

[0124] For example, in some embodiments of the present disclosure, in the second display area A2, the density of the second sub-pixels 20 in different display sub-areas A21 can also be different, that is, the density of the second sub-pixels 20 in a display sub-area A21 can be different from the density of the second sub-pixels 20 in another display sub-area A21.

[0125] For example, referring to Figure 6 , the plurality of first sub-pixels 10 in the first display area A1 and the plurality of second sub-pixels 20 in the second display area A2 both adopt a “diamond arrangement” manner, and the density of the plurality of first sub-pixels 10 in the first display area A1 is the same as the density of a part of the plurality of second sub-pixels 20 in the second display area A2. The density of the part of the plurality of second sub-pixels 20 in the second display area A2 is different from the density of the plurality of first sub-pixels 10 in the first display area A1. In the second display area A2, the density of the second sub-pixels 20 in the first display sub-area A211 is the largest, and the density of the second display sub-area A212, the third display sub-area A213, the fourth display sub-area A214, and the fifth display sub-area A215 is smaller, so that the middle part of the second display area A2 can have a larger light-emitting intensity, and the light-emitting intensity of the plurality of display sub-areas A21 around the first display sub-area A211 is smaller, but embodiments of the present disclosure are not limited thereto.

[0126] For example, referring to Figure 3 , the pixel density of the second display sub-area A212, the third display sub-area A213, the fourth display sub-area A214, and the fifth display sub-area A215 can be the same, and is 1 / 4-3 / 4 of the pixel density of the first display sub-area A211, for example, can be 1 / 3 or 1 / 2, but is not limited thereto, and embodiments of the present disclosure are not limited thereto.

[0127] For example, referring to Figure 11 , similar to the display panel 02 in Figure 11 , in the display panel 05, the arrangement manner of the plurality of second sub-pixels 20 in the second display area A2 is the same as the arrangement manner of the plurality of first sub-pixels 10 in the first display area A1, and the pixel density of the first display sub-area A2101 is smaller than the pixel density of the second display sub-area A2102. For example, the pixel density of the first display sub-area A2101 can be 1 / 4-3 / 4 of the pixel density of the second display sub-area A2102, for example, can be 1 / 3 or 1 / 2, but is not limited thereto. Thus, the middle part of the second display area A2 can have a larger light-emitting intensity, and the light-emitting intensity of the first display sub-area A2101 around the second display sub-area A2102 is smaller, but embodiments of the present disclosure are not limited thereto.

[0128] For example, in some embodiments of the present disclosure, the plurality of display sub-areas in the second display area can also adopt different arrangements, and the pixel density of the second sub-pixels in each display sub-area can be set according to design requirements, which are not limited in the embodiments of the present disclosure.

[0129] For example, in some embodiments of the present disclosure, the pixel density of different regions in the same display sub-area in the second display area can be different.

[0130] Figure 11 A schematic diagram of yet another display panel provided by some embodiments of the present disclosure.

[0131] For example, referring to Figure 12 In the display panel 10, the density of at least part of the second sub-pixels 20 located at the boundary of the display sub-area A21 is greater than the density of at least part of the second sub-pixels 20 located in the interior of the display sub-area A21. The display sub-area A21 is in the shape of “V”, and the at least part of the second sub-pixels 20 located at the boundary of the display sub-area A21 can be the second sub-pixels 20 located between the dashed line and the boundary of the second display area A2, and the at least part of the second sub-pixels 20 located in the interior of the display sub-area A21 can be the second sub-pixels 20 on the side of the dashed line away from the boundary of the second display area A2.

[0132] For example, referring to Figure 12 In the display panel 10, by making the density of at least part of the second sub-pixels 20 located at the boundary of the display sub-area A21 greater, the outline of the display sub-area A21 can be made more clear, so as to highlight the shape features of the display sub-area A21. For example, the pixel pitch of the second sub-pixels 20 located in the interior of the display sub-area A21 can be 1.5-4 times, for example, at least one of 2-3 times, 2.5-3.5 times and 1.5-3 times, the pixel pitch of the adjacent second sub-pixels 20 located at the boundary of the display sub-area A21, which are not limited in the embodiments of the present disclosure.

[0133] For example, in some embodiments of the present disclosure, the density of the second sub-pixels 20 in the same display sub-area A21 of the second display area A2 can change unevenly, for example, the density of the second sub-pixels 20 in the display sub-area A21 can gradually increase or gradually decrease from the middle to the boundary of the display sub-area A21, so as to present a progressive display effect, which can be set according to design requirements, which are not limited in the embodiments of the present disclosure.

[0134] For example, in some embodiments of the present disclosure, the light-emitting area of the pixels in different regions in the same display sub-area in the second display area can be different.

[0135] Figure 11FIG. 7 is a partial schematic view of a display panel provided by some embodiments of the present disclosure.

[0136] For example, referring to FIG. 7, the display panel 11 is different from the display panel 10 in FIG. 6 in that the area of the light-emitting region of at least part of the second sub-pixel 20 located at the boundary of the display sub-region A21 is greater than the area of the light-emitting region of at least part of the second sub-pixel 20 located inside the display sub-region A21, and the rest of the structures are the same. Figure 12 Figure 13 For example, referring to FIG. 7, the area of the light-emitting region of the second sub-pixel 20 located inside the display sub-region A21 can be 1 / 4-3 / 4 of the area of the light-emitting region of the adjacent second sub-pixel 20 located at the boundary of the display sub-region A21, for example, can be at least one of 1 / 4-1 / 3, 1 / 3-1 / 2, and 1 / 2-3 / 4, and embodiments of the present disclosure are not limited thereto.

[0137] By making the area of the light-emitting region of at least part of the second sub-pixel 20 located at the boundary of the display sub-region A21 larger, the outline of the display sub-region A21 can be made more distinct, so as to have a good display effect. Figure 13 For example, in some embodiments of the present disclosure, the area of the light-emitting region of the second sub-pixel 20 in the same display sub-region A21 of the second display region A2 can also change unevenly, so as to present a progressive display effect, which can be set according to design requirements, and embodiments of the present disclosure are not limited thereto.

[0139] FIG. 8 is a partial schematic view of a display panel provided by some embodiments of the present disclosure.

[0140] For example, referring to FIG. 8, the display panel 12 is different from the display panel 04 in FIG. 6 in that the shape of the first display sub-region A2101 and the shape of the second light-transmitting region A2202 in the second display region A2 in the display panel 12 are different from those in the display panel 04, and the rest of the structures are the same as or similar to those in the display panel 04. Figure 5 For example, referring to FIG. 8, the area of the light-emitting region of at least part of the second sub-pixel 20 located at the boundary of the display sub-region A2101 is greater than the area of the light-emitting region of at least part of the second sub-pixel 20 located inside the display sub-region A2101, and the rest of the structures are the same as or similar to those in the display panel 04.

[0141] Figure 13 For example, referring to FIG. 8, the area of the light-emitting region of the second sub-pixel 20 located inside the display sub-region A2101 can be 1 / 4-3 / 4 of the area of the light-emitting region of the adjacent second sub-pixel 20 located at the boundary of the display sub-region A2101, for example, can be at least one of 1 / 4-1 / 3, 1 / 3-1 / 2, and 1 / 2-3 / 4, and embodiments of the present disclosure are not limited thereto. Figure 13 By making the area of the light-emitting region of at least part of the second sub-pixel 20 located at the boundary of the display sub-region A2101 larger, the outline of the display sub-region A2101 can be made more distinct, so as to have a good display effect.

[0142] Figure 13 ​​​The display panel 12 includes a first light-transmissive region A2201, a second light-transmissive region A2202, and a first display sub-region A2101.

For example, each of the display portions of the first display sub-region A2101 includes a pointed portion away from the center of the first display sub-region A2101. For example, the first display portion A2101-1, the second display portion A2101-2, the third display portion A2101-3, the fourth display portion A2101-4, and the fifth display portion A2101-5 each include substantially the same area, but are not limited thereto.

The first light-transmissive region A2201 is located between the outer boundary of the first display sub-region A2101 and a boundary of the second display region A2. The second light-transmissive region A2202 is located within an area surrounded by the inner boundary of the first display sub-region A2101. Figure 13 For example, referring to FIG. 2A, the display panel 12 includes a first display sub-region A2101 and a second display sub-region A2201. The first display sub-region A2101 has an outer boundary in a "star shape", and is located between the first light-transmissive region A2201 and the second light-transmissive region A2202. The first light-transmissive region A2201 is located between the outer boundary of the first display sub-region A2101 and a boundary of the second display region A2. The second light-transmissive region A2202 is located within an area surrounded by the inner boundary of the first display sub-region A2101.

[0145] For example, referring to FIG. 2A, the display panel 12 includes a first display sub-region A2101 and a second display sub-region A2201. The first display sub-region A2101 has an outer boundary in a "star shape", and is located between the first light-transmissive region A2201 and the second light-transmissive region A2202. The first light-transmissive region A2201 is located between the outer boundary of the first display sub-region A2101 and a boundary of the second display region A2. The second light-transmissive region A2202 is located within an area surrounded by the inner boundary of the first display sub-region A2101. Figure 13 For example, referring to FIG. 2A, the display panel 12 includes a first display sub-region A2101 and a second display sub-region A2201. The first display sub-region A2101 has an outer boundary in a "star shape", and is located between the first light-transmissive region A2201 and the second light-transmissive region A2202. The first light-transmissive region A2201 is located between the outer boundary of the first display sub-region A2101 and a boundary of the second display region A2. The second light-transmissive region A2202 is located within an area surrounded by the inner boundary of the first display sub-region A2101.

[0146] For example, referring to FIG. 2A, the display panel 12 includes a first display sub-region A2101 and a second display sub-region A2201. The first display sub-region A2101 has an outer boundary in a "star shape", and is located between the first light-transmissive region A2201 and the second light-transmissive region A2202. The first light-transmissive region A2201 is located between the outer boundary of the first display sub-region A2101 and a boundary of the second display region A2. The second light-transmissive region A2202 is located within an area surrounded by the inner boundary of the first display sub-region A2101. Figure 13In the second display area A2, the second sub-pixels 20 in each display unit can emit light simultaneously or not emit light simultaneously, and the emission patterns of the second sub-pixels 20 in different display units can be different. In the second display state, the emission patterns of the light-emitting elements of the second sub-pixels 20 in all display units located in the second display area A2 are not completely identical. For example, at least one of 2 to 4, 1 to 3, and 1 to 4 of the first display units A2101-1, second display units A2101-2, third display units A2101-3, fourth display units A2101-4, and fifth display units A2101-5 emits light simultaneously, while the light-emitting elements of the second sub-pixels 20 in the other display units do not emit light.

[0147] For example, refer to Figure 14 The light-emitting element of each sub-pixel in the display panel 12 (e.g., the first sub-pixel 10 in the first display area A1 or the second sub-pixel 20 in the second display area A2) can emit light under the drive of the pixel circuit. For example, the pixel circuit of the first sub-pixel 10 or the second sub-pixel 20 can adopt a 7T1C (i.e., seven transistors and one capacitor) structure, but is not limited thereto.

[0148] For example, in at least one embodiment of this disclosure, the light-emitting elements of multiple sub-pixels in the second display area can also be controlled by the same pixel circuit, that is, the light-emitting elements of multiple sub-pixels are all electrically connected to a pixel circuit, thereby reducing the number of pixel circuits and increasing the light transmittance of the second display area, but not limited thereto.

[0149] For example, refer to Figure 15 Each display unit has multiple second sub-pixels 20 whose light-emitting elements can be electrically connected to a pixel circuit to have the same display state. The pixel circuits connected to the light-emitting elements of the second sub-pixels 20 in different display units can be different so that the second sub-pixels 20 in different display units have different light-emitting conditions. The specific settings can be made according to design requirements, and the embodiments disclosed herein do not limit this.

[0152] For example, referring to Figure 15 In the display panel 13, the area where the second display area A2 is located is in the shape of a "star", and no second light-transmitting area A2202 (see Figure 14 ) is arranged in the second display area A2, so that a plurality of second sub-pixels 20 are arranged continuously in the second display area A2, and the area in the shape of a "star" where the second display area A2 is located is a whole display area, which is beneficial to improve the display effect of the second display area A2.

[0153] For example, referring to Figure 15 The shape of the display sub-area A21 and the shape of the light-transmitting area A22 in the second display area A2 in the display panel 14 are different from those in the display panel 13, and the rest of the structures are the same as or similar to those of the display panel 13.

[0155] For example, referring to Figure 16 The shape of the display sub-area A21 and the shape of the light-transmitting area A22 in the second display area A2 in the display panel 15 are different from those in the display panel 13, and the rest of the structures are the same as or similar to those of the display panel 13. Figure 13

[0156] For example, referring to Figure 17 In the display panel 15, the area where the second display area A2 is located is in the shape of an "X", and no second light-transmitting area A2202 (see Figure 18 ) is arranged in the second display area A2, so that a plurality of second sub-pixels 20 are arranged continuously in the second display area A2, and the area in the shape of an "X" where the second display area A2 is located is a whole display area, which is beneficial to improve the display effect of the second display area A2.

Figure 17 FIGS. 2(A) to (D) are schematic diagrams of a second display area of a display panel according to some embodiments of the present disclosure. Figure 18 FIGS. 3(A) to (C) are schematic diagrams of display panels according to some embodiments of the present disclosure.

[0159] For example, referring to FIG. 1(A) and FIG. 1(B), Figure 17 For example, referring to FIG. 1(A) and FIG. 1(B), Figure 18 For example, referring to FIG. 1(A) and FIG. 1(B),

[0162] For example, in some embodiments of the present disclosure, the number of the second display area A2 can be greater than 1, and the plurality of second display areas A2 can be arranged at different positions or have different shapes according to design requirements.

[0163] For example, referring to FIG. 1(C) and FIG. 1(D), Figure 17 For example, referring to FIG. 1(C) and FIG. 1(D), Figure 18 For example, referring to FIG. 1(C) and FIG. 1(D),

[0164] For example, referring to FIG. 1(D), Figure 19 For example, referring to FIG. 1(D),

[0165] Figure 19 FIG. 1(E) shows a second display area A2 in a track shape.

[0166] As shown in FIG. 1(A), the second display area A2 is in a circular shape, the display sub-area A21 is in a pentagram shape, and the light-transmitting area A22 is the area of the second display area A2 other than the pentagram. Figure 19 For example, referring to FIG. 1(A) and FIG. 1(B),

[0167] and Figure 19 Compared to (A), Figure 19 The light-transmitting area A22 shown in (B) includes a first light-transmitting area A2201 and a second light-transmitting area A2202.

[0168] like Figure 19 As shown in (C), the second display area A2 is circular, the display sub-area A21 is X-shaped, and the light-transmitting area A22 is the area of ​​the second display area A2 other than the X-shaped area.

[0169] like Figure 19 As shown in (D), the second display area A2 is circular, and the display sub-area A21 is heart-shaped.

[0170] Figure 20 (C) and (D) show the second sub-pixel 20. Figure 20 (A) and (B) are not shown. The second sub-pixel 20 is located in the display sub-area A21.

[0171] like Figure 20 As shown in (A) to (C), no pixel circuits are set in the light-transmitting area A22 to improve the light transmittance of the light-transmitting area. The light-transmitting area A22 transmits light but does not emit light.

[0172] For example, refer to Figure 21 (B) and Figure 21 (C) The light-emitting element of the second sub-pixel 20 can be located in the display sub-area A21, and the pixel circuit of the second sub-pixel 20 can be located in the first display area A1. The display substrate may also include connecting wires CL, through which the light-emitting element of the second sub-pixel 20 can be electrically connected to the pixel circuit. For example, the first electrode in the light-emitting element of the second sub-pixel 20 can be connected to the drain in the corresponding pixel circuit through the connecting wires CL, but is not limited thereto.

[0173] Figure 21 This is an equivalent diagram of a pixel circuit provided according to some embodiments of the present disclosure.

[0174] For example, refer to Figure 21 The light-emitting control transistor T6 in the pixel circuit 200 can be the first light-emitting control transistor T6. The pixel circuit 200 also includes a second reset transistor T1, a threshold compensation transistor T2, a driving transistor T3, a data writing transistor T4, a second light-emitting control transistor T5, a first reset control transistor T7, and a storage capacitor C.

[0175] For example, the display substrate also includes reset power signal lines, scan signal lines, power signal lines, reset control signal lines, light emission control signal lines, and data lines.

[0176] For example, refer to Figure 21The first electrode of the threshold compensation transistor T2 is electrically connected with the first electrode of the driving transistor T3, and the second electrode of the threshold compensation transistor T2 is electrically connected with the gate electrode of the driving transistor T3; the first electrode of the first reset control transistor T7 is electrically connected with the reset power signal line to receive the reset signal Vinit, and the second electrode of the first reset control transistor T7 is electrically connected with the first electrode of the light emitting element 100 (i.e. the N4 node); the first electrode of the data write transistor T4 is electrically connected with the second electrode of the driving transistor T3, the second electrode of the data write transistor T4 is electrically connected with the data line to receive the data signal Data, and the gate electrode of the data write transistor T4 is electrically connected with the scanning signal line to receive the scanning signal Gate; the first electrode of the storage capacitor C is electrically connected with the power signal line, and the second electrode of the storage capacitor C is electrically connected with the gate electrode of the driving transistor T3; the gate electrode of the threshold compensation transistor T2 is electrically connected with the scanning signal line to receive the compensation control signal; the gate electrode of the first reset transistor T7 is electrically connected with the reset control signal line to receive the reset control signal Reset(N+1); the first electrode of the second reset transistor T1 is electrically connected with the reset power signal line to receive the reset signal Vinit, the second electrode of the second reset transistor T1 is electrically connected with the gate electrode of the driving transistor T3, and the gate electrode of the second reset transistor T1 is electrically connected with the reset control signal line to receive the reset control signal Reset(N); the gate electrode of the first light emitting control transistor T6 is electrically connected with the light emitting control signal line to receive the light emitting control signal EM; the first electrode of the first light emitting control transistor T6 is electrically connected with the first electrode of the driving transistor T3, and the second electrode of the first light emitting control transistor T6 is electrically connected with the first electrode of the light emitting element 100; the first electrode of the second light emitting control transistor T5 is electrically connected with the power signal line to receive the first power signal VDD, the second electrode of the second light emitting control transistor T5 is electrically connected with the second electrode of the driving transistor T3, the gate electrode of the second light emitting control transistor T5 is electrically connected with the light emitting control signal line to receive the light emitting control signal EM, and the second electrode of the light emitting element 100 is connected with the voltage terminal VSS. The above power signal line refers to the signal line outputting the voltage signal VDD, which can be connected with the voltage source to output a constant voltage signal, for example, a positive voltage signal.

[0177] For example, with reference to Figure 21, the scan signal and the compensation control signal can be the same, that is, the gate of the data writing transistor T3 and the gate of the threshold compensation transistor T2 can be electrically connected to the same signal line to receive the same signal, reducing the number of signal lines. For example, the gate of the data writing transistor T3 and the gate of the threshold compensation transistor T2 can also be electrically connected to different signal lines, respectively, that is, the gate of the data writing transistor T3 is electrically connected to a first scan signal line, and the gate of the threshold compensation transistor T2 is electrically connected to a second scan signal line, and the signals transmitted by the first scan signal line and the second scan signal line can be the same or different, so that the gate of the data writing transistor T3 and the gate of the threshold compensation transistor T2 can be separately controlled, increasing the flexibility of controlling the pixel circuit 200.

[0178] For example, referring to Figure 21 , the first light emitting control transistor T6 and the second light emitting control transistor T5 can receive the same light emitting control signal, that is, the gate of the first light emitting control transistor T6 and the gate of the second light emitting control transistor T5 can be electrically connected to the same signal line to receive the same signal, reducing the number of signal lines. For example, the gate of the first light emitting control transistor T6 and the gate of the second light emitting control transistor T5 can also be electrically connected to different light emitting control signal lines, respectively, and the signals transmitted by different light emitting control signal lines can be the same or different.

[0179] For example, referring to Figure 21 , the first reset transistor T7 and the second reset transistor T1 can receive the same reset control signal, that is, the gate of the first reset transistor T7 and the gate of the second reset transistor T1 can be electrically connected to the same signal line to receive the same signal, reducing the number of signal lines. For example, the gate of the first reset transistor T7 and the gate of the second reset transistor T1 can also be electrically connected to different reset control signal lines, and the signals on the different reset control signal lines can be the same or different.

[0180] For example, referring to Figure 21 , during the first stage of the picture display, the second reset transistor T1 is turned on to initialize the voltage of the N1 node; during the second stage of the picture display, the data data is stored in the N1 node through the data writing transistor T4, the driving transistor T3 and the threshold compensation transistor T2; during the third light emitting stage, the second light emitting control transistor T5, the driving transistor T3 and the first light emitting control transistor T6 are all turned on, and the light emitting element 100 is forward biased to emit light.

[0181] It should be noted that in the embodiments of the present disclosure, each pixel circuit can be Figure 22Besides the 7T1C (seven transistors and one capacitor) structure shown, other structures including different numbers of transistors are also possible, such as 7T2C, 6T1C, 6T2C, or 9T2C structures. This disclosure does not limit the specific implementation of these structures. The equivalent diagram of the pixel circuit in the display substrate shown in the above embodiments can be compared with... Figure 23 The equivalent diagram of the pixel circuit 200 shown is the same.

[0182] Figure 24 This is a cross-sectional schematic diagram of a display panel provided according to some embodiments of the present disclosure; Figure 25 This is another cross-sectional schematic diagram of a display panel provided according to some embodiments of the present disclosure; Figure 26 This is yet another cross-sectional schematic diagram of a display panel provided according to some embodiments of the present disclosure; Figure 27 This is yet another cross-sectional schematic diagram of a display panel provided according to some embodiments of the present disclosure; Figure 20 This is yet another cross-sectional schematic diagram of a display panel provided according to some embodiments of the present disclosure; Figure 22 to Figure 26 A cross-sectional view of a display panel provided for an embodiment of this disclosure.

[0183] For example, refer to Figure 20 (A) to (C) Figure 22 to Figure 26 The display panel includes a substrate BS, multiple light-emitting elements M, and multiple pixel circuits C. Each light-emitting element M includes a light-emitting functional layer EL and a first electrode L1 and a second electrode L2 located on either side of the light-emitting functional layer EL along a direction perpendicular to the substrate BS. The first electrode L1 is located between the light-emitting functional layer EL and the substrate BS. Each pixel circuit C is electrically connected to the first electrode L1 of at least one light-emitting element M and is configured to drive at least one light-emitting element M to emit light.

[0184] For example, refer to Figure 20 (A) to (C) Figure 22 to Figure 26 The plurality of light-emitting elements M include a first light-emitting element M1 corresponding to a first sub-pixel and a second light-emitting element M2 corresponding to a second sub-pixel. That is, the first sub-pixel includes the first light-emitting element M1, and the second sub-pixel includes the second light-emitting element M2.

[0185] For example, refer to Figure 20 (A) to (C) Figure 22 to Figure 26 The multiple pixel circuits C include a first pixel circuit C1 and a second pixel circuit C2.

[0186] For example, refer to Figure 20 (A) to (C) Figure 22 to Figure 26 The first pixel circuit C1 is located in the first display area A1, and the second pixel circuit C2 is located in the first display area A1 or in the display sub-area A21.

[0187] As Figure 22 to Figure 27 (A) to (C) shown in Figure 22 to Figure 27 , the light-transmitting area A22 is not provided with any pixel circuit to avoid affecting the light transmittance.

[0188] For example, referring to Figure 22 to Figure 26 , the display panel can further include, in sequence along a direction perpendicular to the substrate BS, a buffer layer BF, a gate insulating layer GI, an interlayer insulating layer ILD, a planarization layer PLN, and a pixel definition layer PDL.

[0189] For example, referring to Figure 20 , the active layer SM is disposed on the buffer layer BF, the gate insulating layer GI is provided with the gate GT, and the source E1 and the drain E2 are respectively connected with the active layer SM.

[0190] Referring to Figure 22 , in the first display area A1, the first electrode L1 of the first light-emitting element M1 of the first sub-pixel is electrically connected with the drain E2.

[0191] For example, referring to Figure 20 (A) and Figure 20 , each first sub-pixel located in the first display area A1 and each second sub-pixel located in the second display area A2 include a light-emitting element, and the display panel further includes a pixel circuit C connected with the light-emitting element M, and the pixel circuit C is configured to drive the light-emitting element M to emit light. For example, in the first display area A1, the number of first light-emitting elements M1 of the first sub-pixel can be the same as the number of first pixel circuits C1, and the first pixel circuit C1 of the first sub-pixel is located in the first display area A1. In the second display area A2, the number of second light-emitting elements M2 of the second sub-pixel can also be the same as the number of second pixel circuits C2, and the second pixel circuit C2 is located in the display sub-area A21 in the second display area A2. Thus, the first light-emitting element M1 of each first sub-pixel can be independently controlled by the first pixel circuit C1 connected thereto, and the second light-emitting element M2 of each second sub-pixel can be independently controlled by the second pixel circuit C2 connected thereto, but embodiments of the present disclosure are not limited thereto. Of course, the number of light-emitting elements connected by each pixel circuit is not limited to the above description, and can be determined as needed.

[0192] For example, referring to Figure 23 to Figure 25 (B), Figure 20 (C), Figure 23In order to improve the light transmittance of the second display area A2, the second pixel circuit C2 can be arranged outside the second display area A2, for example, can be arranged in the first display area A1, so that only the second light emitting element M2 of the second sub-pixel is arranged in the second display area A2. That is, the light transmittance of the second display area A2 is improved by arranging the second light emitting element M2 and the second pixel circuit C2 separately, but embodiments of the present disclosure are not limited thereto.

[0193] For example, referring to Figure 24 (C) and Figure 24 The first electrode L1 of the first light emitting element M1 is connected with the first electrode L1 of at least one second light emitting element M2, and is electrically connected to the first pixel circuit C1 together. For example, the first electrode L1 of the plurality of second sub-pixels located in the second display area A2 can be connected with the first electrode L1 of the first sub-pixel in the first display area A1, so that the second light emitting element M2 of the plurality of second sub-pixels can have the same light emitting state as the first light emitting element M1 of the first sub-pixel in the first display area A1. That is, in some embodiments of the present disclosure, the first electrode L1 of the plurality of second light emitting elements M2 of the plurality of second sub-pixels located in the second display area A2 can be connected with the same first pixel circuit C1, but not limited thereto. Thus, the number of second pixel circuits C2 in the second display area A2 can be reduced, and no pixel circuit can be arranged in the second display area A2 to improve the light transmittance.

[0194] For example, referring to Figure 25 The planarization layer PLN in the display panel includes a first planarization layer PLN1 and a second planarization layer PLN2 arranged in sequence along a direction perpendicular to the substrate BS. The first planarization layer PLN1 is provided with a first connection portion IO1. The second light emitting element M2 of the second sub-pixel is located in the second display area A2, and the second pixel circuit C2 connected with the second light emitting element M2 is located in the first display area A1.

[0195] For example, referring to Figure 25 The first electrode L1 of the second light emitting element M2 is connected with the first connection portion IO1, and the first connection portion IO1 is connected with the drain electrode E2 in the second pixel circuit C2, so that the first electrode L1 of the second light emitting element M2 is connected to the drain electrode E2 in the second pixel circuit C2.

[0196] In this way, the first electrode L1 of the second sub-pixel located in the second display area A2 can be flexibly and well connected with the second pixel circuit C2, which is conducive to realizing the space utilization of the display panel.

[0197] For example, referring to Figure 20The planarization layer PLN in the display panel includes a first planarization layer PLN1, a second planarization layer PLN2, and a third planarization layer PLN3 arranged in sequence along a direction perpendicular to the substrate base plate BS.
