[0068] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0069] Currently, in virtual shooting scenarios, a full-wall display screen is typically used as a background wall. Depending on the needs of the virtual scene, the screen can display different background images. The target object (e.g., a person or animal) can be positioned appropriately on the light-emitting side of the display screen, and then the shooting device can simultaneously capture images of both the display screen and the target object on the light-emitting side of the screen, thus obtaining an image that places the target object within a specific virtual scene.

[0070] However, current displays typically emit only red, green, and blue light from their individual pixel groups. Each pixel group can combine these rays to varying degrees, allowing the display to project a specific background image. For a target object on the light-emitting side of the display, only red, green, and blue light typically reaches it. Therefore, the light illuminating the target object lacks wavelengths other than red, green, and blue, resulting in a significant difference between the color of the target object on the light-emitting side and its true color. Consequently, when a photograph is taken of the target object on the light-emitting side of the display, the resulting image shows a poor representation of the target object, leading to poor photographic quality.

[0071] Please refer to Figure 1, which is a top view of a display substrate provided in an embodiment of this application. The display substrate 000 may include: a back plate 100, and a first light-emitting portion 200 and a second light-emitting portion 300 located on one side of the back plate 100.

[0072] The plurality of first light-emitting elements 200 in the display substrate 000 can be divided into a plurality of pixel groups, and a pixel group can include at least two first light-emitting elements 300. The same pixel group is used to emit at least two different colors of light. For example, the at least two colors of light emitted by the same pixel group are distributed as red light, green light, and blue light. In one possible implementation, the same pixel group can include three first light-emitting elements 200, and the colors of the light emitted by these three first light-emitting elements 200 are distributed as red, green, and blue. In another possible implementation, the same pixel group can include four first light-emitting elements 200, and the colors of the light emitted by two of these four first light-emitting elements 200 can be green and blue, respectively, while the colors of the light emitted by the other two first light-emitting elements 200 are both red.

[0073] The colors of the light emitted by each of the second light-emitting portions 300 in the display substrate 000 can all be the same, and the colors of the light emitted by the second light-emitting portions 300 are different from the colors of the light emitted by each of the first light-emitting portions 200. For example, the color of the light emitted by the second light-emitting portions 300 is white or orange.

[0074] In this embodiment, the state of the display substrate 000 may include a display state and an illumination state. When the display substrate 000 is in the display state, at least a portion of the first light-emitting portion 200 emits light outwards, enabling the display substrate 000 to display a screen. When the display substrate 000 is in the illumination state, at least a portion of the second light-emitting portion 300 emits light outwards, or at least a portion of the first light-emitting portion 200 and at least a portion of the second light-emitting portion 300 emit light outwards simultaneously.

[0075] It should be noted that since each pixel group in the display substrate 000 can emit red, green, and blue light, and can combine these light rays to varying degrees, the display screen can present a specific image. Therefore, when the display substrate 000 is in display mode, the light emitted by at least a portion of the first light-emitting parts 200 in the display substrate 000 allows the display substrate 000 to present a specific image. Furthermore, when the display substrate 000 is in display mode, all the second light-emitting parts 300 are in an off state, ensuring that the second light-emitting parts 300 do not affect the light emission of the first light-emitting parts 200 in the display substrate 000. This guarantees a good display effect when the display substrate 000 presents an image through at least a portion of the first light-emitting parts 200.

[0076] It should also be noted that, since the color of the light emitted from the second light-emitting part 300 can be white or orange, the embodiments of this application will be illustrated using the following two optional implementation methods as examples:

[0077] In a first optional implementation, when the light emitted by the second light-emitting unit 300 is white, the light emitted by the second light-emitting unit 300 is white light. This white light has a wide wavelength range, which can better simulate natural light. Therefore, when the display substrate 000 is in an illuminated state, each of the second light-emitting units 300 in the display substrate 000 can emit light outwards, while each of the first light-emitting units 200 in the display substrate 000 is in an off state. In this case, the display substrate 000 can emit white light with a wide wavelength range as a whole, so that the display substrate 000 can have a better illumination and supplementary lighting effect.

[0078] For example, please refer to Figure 2, which is a schematic diagram of the spectrum of light emitted by a display substrate when it is in display and illumination states according to an embodiment of this application. When the display substrate 000 is in display state, the spectrum curve of the light emitted by the display substrate 000 is curve a. Since all the second light-emitting parts 300 are in an off state when the display substrate 000 is in display state, only at least some of the first light-emitting parts 200 need to emit light, so that each pixel group can combine red, green and blue light to different degrees. Therefore, when the display substrate 000 is in display state, the light emitted by the display substrate 000 only includes red light, green light and blue light, and there is no light of other wavelengths besides red, green and blue light.

[0079] When the display substrate 000 is illuminated, the spectral curve of the light emitted by the display substrate 000 is curve b. Since each of the first light-emitting units 200 is in an off state when the display substrate 000 is illuminated, while each of the second light-emitting units 300 can emit white light, the light emitted by the display substrate 000 when it is illuminated is white light with a wide wavelength range. Here, the wavelength range of white light can include the wavelength range of red light, green light, and blue light, as well as the wavelength range of other colors besides red, green, and blue.

[0080] In a second optional implementation, when the light emitted by the second light-emitting part 300 is orange, the light emitted by the second light-emitting part 300 is orange light. When the display substrate 000 is in an illuminated state, each of the first light-emitting parts 200 and each of the second light-emitting parts 300 in the display substrate 000 can emit light outward simultaneously. In this way, the orange light emitted by each of the second light-emitting parts 300 can be combined with the red, green, and blue light emitted by multiple first light-emitting parts 200, resulting in a wider wavelength range of the combined light, which is closer to natural light, thereby enabling the display substrate 000 to have a better illumination and supplementary lighting effect.

[0081] For example, please refer to Figure 3, which is a schematic diagram of the spectrum of light emitted by another display substrate in display and illumination states according to an embodiment of this application. When each of the first light-emitting parts 200 in the display substrate 000 emits light outward, and each of the second light-emitting parts 300 is in an off state, the spectrum curve of the light emitted by the display substrate 000 is curve c. In this state, the light emitted by the display substrate 000 includes red light, green light, and blue light.

[0082] When each of the second light-emitting parts 300 in the display substrate 000 emits light outward, while each of the first light-emitting parts 200 is in an off state, the spectral curve of the light emitted from the display substrate 000 is curve d. In this state, the light emitted from the display substrate 000 is all orange light.

[0083] When each of the first light-emitting parts 200 and each of the second light-emitting parts 300 in the display substrate 000 emits light simultaneously, that is, when the display substrate 000 is in an illuminated state, the light emitted by the display substrate 000 simultaneously includes: red light, green light, blue light, and orange light. These four types of light can be combined, and the spectral curve of the combined light is curve e. According to curve e, when red light, green light, blue light, and orange light are combined, the wavelength range of the combined light is relatively wide, which is closer to the spectrum of natural light. For example, the wavelength range of the combined light can include the wavelength range of red light, the wavelength range of green light, and the wavelength range of blue light, as well as the wavelength range of light of other colors other than red, green, and blue.

[0084] In this embodiment, when the display substrate 000 is in display mode, it can display a screen image; when in illumination mode, it provides good illumination and supplementary lighting. Therefore, during virtual photography of a target object on the light-emitting side of a display screen integrating this display substrate 000, the display screen can periodically display a background image and a supplementary lighting image. The background image refers to the image displayed when the display substrate 000 is in display mode; the supplementary lighting image refers to the image displayed when the display substrate 000 is in illumination mode. Thus, during the display screen displaying a screen image, the shooting device can use a background image with the target object removed, retaining only the background; during the display screen displaying a screen image, the shooting device can use a main image of the target object with the background removed. Furthermore, during the display screen displaying a supplementary lighting image, the wavelength range of the light emitted by the display substrate 000 is relatively wide. Therefore, the color of the target object located on the light-emitting side of the display screen differs little from its true color. This ensures that when the display screen displays a supplementary lighting image, the target object captured on the light-emitting side will have a good appearance. Subsequent stitching of the background and subject images results in a well-displayed target image that includes both the target object and the background shown on the screen, effectively improving the quality of the captured image.

[0085] In summary, the display substrate provided in this application includes a back plate and a plurality of first light-emitting portions and second light-emitting portions located on one side of the back plate. When the display substrate is in a display state, it can display an image through the first light-emitting portions; when the display substrate is in an illumination state, it can provide good illumination through the second light-emitting portions or through both the first and second light-emitting portions. Therefore, during the virtual shooting of a target object on the light-emitting side of a display screen integrating this display substrate, the display screen can periodically display a background image and an illuminated image. During the display screen displaying an image, the shooting device can use a background image with the target object removed and the background image retained; during the display screen displaying an image, the shooting device can use a main image of the target object with the background removed and the main image retained. After subsequently stitching the background image and the main image together, the resulting target image containing both the target object and the background image displayed on the display screen has a better display effect, thereby effectively improving the shooting effect of the target object.

[0086] In this embodiment, the distribution of the plurality of first light-emitting parts 200 and the plurality of second light-emitting parts 300 on the back plate 100 can be implemented in several ways. This embodiment will illustrate these two possible implementations as examples:

[0087] In one possible implementation, as shown in Figure 1, the backplate 100 can have multiple first light zones Q1 arranged in an array and multiple second light zones Q2 arranged in an array. Here, the multiple rows of first light zones Q1 and multiple rows of second light zones Q2 can be arranged alternately. That is, a row of second light zones Q2 is distributed between two adjacent rows of first light zones Q1, and a row of first light zones Q1 is distributed between two adjacent rows of second light zones Q2.

[0088] Each of the multiple first light zones Q1 can correspond one-to-one with multiple pixel groups, and each of the first light-emitting parts 101 in each pixel group can be distributed within the corresponding first light zone Q1. For example, a pixel group distributed within each first light zone Q1 can contain three first light-emitting parts 101, which are used to emit red light, green light, and blue light, respectively.

[0089] Multiple second lamp zones Q2 can correspond to multiple second light-emitting parts 300, and at least one second light-emitting part 300 is distributed in each second lamp zone Q2. For example, the multiple second lamp zones Q2 correspond one-to-one with the multiple second light-emitting parts 300, and each second lamp zone Q2 corresponds to one second light-emitting part 300.

[0090] In this embodiment, the plurality of first light areas Q1 and the plurality of second light areas Q2 on the backplate 100 can be arranged in multiple columns along the first direction X, and can also be arranged in multiple columns along the second direction Y. Here, the first direction X may intersect with the second direction Y; for example, the first direction X may be perpendicular to the second direction Y.

[0091] In this application, multiple rows of first light zones Q1 and multiple rows of second light zones Q2 are arranged alternately, and / or multiple columns of first light zones Q1 and multiple columns of second light zones Q2 are arranged alternately. Here, there are various ways to arrange the first light zones Q1 and the second light zones Q2. This application's embodiments illustrate this with the following three different arrangement methods as examples:

[0092] In the first scenario, as shown in Figure 1, with alternating rows of first light zones Q1 and second light zones Q2, and alternating columns of first light zones Q1 and second light zones Q2, in the first direction X, there is a column of first light zones Q1 between two adjacent columns of first light zones Q1, and a column of first light zones Q1 between two adjacent columns of second light zones Q2; in the second direction Y, there is a row of second light zones Q2 between two adjacent rows of first light zones Q1, and a row of first light zones Q1 between two adjacent rows of second light zones Q2. That is, a second light zone Q2 is located at the center of every 2*2 first light zones Q1.

[0093] In this situation, since the light emitted by the second light-emitting parts 300 distributed in the second lamp zone Q2 is white, the second light-emitting parts 300 in the off state also appear white. Furthermore, on the side of the backplate 100 where light is emitted, all areas except for the first lamp zones Q1 and Q2 are covered with a black light-absorbing layer. With one second lamp zone Q2 located at the center of every 2*2 first lamp zones Q1, the second light-emitting parts 300 in each second lamp zone Q2 are surrounded by a black light-absorbing layer, resulting in a relatively uniform color distribution around them. Therefore, when a portion of the display area of ​​the display substrate 000 needs to display a dark image (i.e., a black image), the second light-emitting parts 300 in the area requiring a dark image have a smaller impact on the displayed dark image, allowing the display substrate 000 to exhibit a better dark image effect. Furthermore, since the display screen integrating this display substrate 000 typically contains many areas that need to be dark during the display of the background image, the presence of a second lamp area Q2 at the center of every 2*2 first lamp areas Q1 ensures that the display screen can present a background image with better effect.

[0094] In the second scenario, as shown in Figure 4, which is a top view of another display substrate provided in an embodiment of this application, when multiple rows of first lamp areas Q1 and multiple rows of second lamp areas Q2 are arranged alternately, in the second direction Y, a row of second lamp areas Q2 is distributed between two adjacent rows of first lamp areas Q1, and a row of first lamp areas Q1 is distributed between two adjacent rows of second lamp areas Q2. That is, in the second direction Y, a second lamp area Q2 is distributed between every two adjacent first lamp areas Q1; and a first lamp area Q1 is distributed between every two adjacent second lamp areas Q2.

[0095] In the third scenario, as shown in Figure 5, which is a top view of another display substrate provided in an embodiment of this application, when multiple columns of first lamp areas Q1 and multiple columns of second lamp areas Q2 are arranged alternately, in the first direction X, a column of second lamp areas Q2 is distributed between two adjacent columns of first lamp areas Q1, and a column of first lamp areas Q1 is distributed between two adjacent columns of second lamp areas Q2. That is, in the first direction X, a second lamp area Q2 is distributed between every two adjacent first lamp areas Q1; and a first lamp area Q1 is distributed between every two adjacent second lamp areas Q2.

[0096] A second possible implementation is shown in Figure 6, which is a top view of another display substrate provided in an embodiment of this application. The back panel 100 may have multiple light-emitting lamp areas Q3 arranged in an array. Here, the multiple light-emitting lamp areas Q3 may be arranged in multiple columns along the first direction X and in multiple rows along the second direction Y.

[0097] In this design, the multiple light-emitting areas Q3 of the backplate 100 can correspond one-to-one with multiple pixel groups, and the multiple light-emitting areas Q3 can also correspond one-to-one with multiple second light-emitting parts 102. Within the same light-emitting area Q3, each of the corresponding pixel groups' first light-emitting parts 101 and corresponding second light-emitting parts 102 can be distributed. For example, a pixel group distributed within each light-emitting area Q3 can contain three first light-emitting parts 101, which are used to emit red, green, and blue light, respectively. That is, each light-emitting area Q3 contains three first light-emitting parts 101 and one second light-emitting part 102, and these four light-emitting parts are used to emit red, green, blue, and white light, respectively.

[0098] In this embodiment, regardless of whether one side of the backplate 100 has multiple first lamp areas Q1 and multiple second lamp areas Q2, or one side of the backplate 100 has only multiple light-emitting lamp areas Q3, the backplate 100 integrates two types of signal lines, enabling the backplate 100 to control the light emission of each first light-emitting part 200 and second light-emitting part 300 through these two signal lines. The different types of lamp areas distributed on the backplate 100 are illustrated in the following two aspects in this embodiment.

[0099] Firstly, when a backplane 100 has multiple first lamp areas Q1 and multiple second lamp areas Q2 on one side, as shown in FIG7, FIG7 is a top view of the internal wiring of a backplane provided in an embodiment of the present application. The backplane 100 integrates multiple sets of first signal lines 101 and multiple sets of second signal lines 102. Here, the extension direction of the first signal lines 101 may intersect with the extension direction of the second signal lines 102.

[0100] A set of first signal lines 101 in the backplate 100 can be electrically connected to the first electrode of each light-emitting part in a row of first lamp areas Q1 and a row of second lamp areas Q2 arranged along the extension direction of the first signal lines 101; a set of second signal lines 102 in the backplate 100 can be electrically connected to the second electrode of each light-emitting part in a row of first lamp areas Q1 and a row of second lamp areas Q2 arranged along the extension direction of the second signal lines 102.

[0101] For example, a set of first signal lines 101 may include one or two first signal lines 101. When there is only one first signal line 101 in the set, it is electrically connected to the first electrode of each light-emitting part in a row of first lamp areas Q1 and a row of second lamp areas Q2. When there are two first signal lines 101 in the set, one first signal line Q1 is electrically connected to the first electrode of each first light-emitting part 200 in a row of first lamp areas, and the other first signal line 101 is electrically connected to the first electrode of each second light-emitting part 300 in a row of second lamp areas Q2.

[0102] A set of second signal lines 102 includes multiple second signal lines 102, and the number of second signal lines 102 in the set is equal to the sum of the number of first light-emitting parts 200 in a first lamp zone Q1 and the number of second light-emitting parts 300 in a second lamp Q2. Specifically, a portion of the second signal lines 102 in the set corresponds one-to-one with multiple first light-emitting parts 200 in the same first lamp zone Q1, and one second signal line 102 is electrically connected to the second electrode of each corresponding first light-emitting part 200 in a row of first lamp zones Q1; another portion of the second signal lines 102 in the set corresponds one-to-one with at least one second light-emitting part 300 in the same second lamp zone Q2, and one second signal line 102 is electrically connected to the second electrode of each corresponding second light-emitting part 300 in a row of second lamp zones Q2.

[0103] It should be noted that, in one possible scenario, the extension direction of the first signal line 101 can be parallel to the first direction X, and the extension direction of the second signal line 102 can be parallel to the second direction Y. In another possible scenario, the extension direction of the first signal line 101 can also be parallel to the second direction Y, and the extension direction of the second signal line 102 can be parallel to the first direction X. This application embodiment does not limit this. Furthermore, a set of first signal lines 101 may include one first signal line 101 or two first signal lines 101. This application embodiment also does not limit this. In addition, since there are multiple possible distributions of the first lamp area Q1 and the second lamp area Q2 on the backplane 100, this application embodiment will provide the following five possible wiring configurations based on different combinations.

[0104] The first possible wiring configuration is shown in Figure 7. In the case of alternating rows of first lamp zones Q1 and second lamp zones Q2, and alternating columns of first lamp zones Q1 and second lamp zones Q2, if the extension direction of the first signal line 101 is parallel to the first direction X, and the extension direction of the second signal line 102 is parallel to the second direction Y, and one set of first signal lines 101 includes two first signal lines 101, then multiple sets of first signal lines 101 can correspond one-to-one with multiple rows of first lamp zones Q1, and multiple sets of first signal lines 101 can also correspond one-to-one with multiple rows of second lamp zones Q2. Similarly, multiple sets of second signal lines 102 can correspond one-to-one with multiple columns of first lamp zones Q1, and multiple sets of second signal lines 102 can also correspond one-to-one with multiple columns of second lamp zones Q2.

[0105] For example, two first signal lines in a set of first signal lines 101 are first signal line 101a and first signal line 101b. First signal line 101a in the set of first signal lines 101 can be electrically connected to the first electrode of each first light-emitting part 200 in a corresponding row of first lamp areas Q1; first signal line 101b in the set of first signal lines 101 can be electrically connected to the first electrode of each second light-emitting part 102 in a corresponding row of second lamp areas Q2. Here, the first electrode of each first light-emitting part 200 in the same first lamp area Q1 can be simultaneously electrically connected to a corresponding first signal line 101a. In this case, among the multiple first signal lines 101 in the backplate 100, every two adjacent first signal lines 101 can be divided into a set of first signal lines 101. That is, the multiple first signal lines 101a and multiple first signal lines 101b in the backplate 100 are arranged alternately in the second direction Y.

[0106] Since the number of second signal lines 102 in a set of second signal lines 102 is equal to the sum of the number of first light-emitting parts 200 in a first lamp zone Q1 and the number of second light-emitting parts 300 in a second lamp zone Q2, this explanation will be based on the example of a first lamp zone Q1 including three first light-emitting parts 200, which are used to emit red light, green light, and blue light respectively, and the example of a second lamp zone Q2 including one second light-emitting part 300 for emitting white light. Therefore, a set of second signal lines 102 can include four second signal lines: second signal line 102R, second signal line 102G, second signal line 102B, and second signal line 102W.

[0107] Specifically, the second signal line 102R can correspond to the first light-emitting part 200 in the first lamp area Q1 that emits red light; the second signal line 102G can correspond to the first light-emitting part 200 in the first lamp area Q1 that emits green light; the second signal line 102B can correspond to the first light-emitting part 200 in the first lamp area Q1 that emits blue light; and the second signal line 102W can correspond to a second light-emitting part 300 in the second lamp area Q2.

[0108] Therefore, the second signal line 102R in a set of second signal lines 102 can be electrically connected to the second electrode of each first light-emitting part 200 emitting red light in a corresponding column of first light areas Q1; the second signal line 102G in a set of second signal lines 102 can be electrically connected to the second electrode of each first light-emitting part 200 emitting green light in a corresponding column of first light areas Q1; the second signal line 102B in a set of second signal lines 102 can be electrically connected to the second electrode of each first light-emitting part 200 emitting blue light in a corresponding column of first light areas Q1; and the second signal line 102W in a set of second signal lines 102 can be electrically connected to the second electrode of each second light-emitting part 300 in a corresponding column of second light areas Q2. In this case, the second signal lines 102R, 102G, and 102B in a set of second signal lines 102 need to be connected to the three first light-emitting parts 200 in the same first light area Q1, respectively. Therefore, the second signal lines 102R, 102G, and 102B in a set of second signal lines 102 are arranged continuously in the second direction Y.

[0109] The second possible wiring configuration is shown in Figure 8, which is a top view of another backplane internal wiring configuration provided in an embodiment of this application. In the case where multiple rows of first lamp zones Q1 and multiple rows of second lamp zones Q2 are alternately arranged, and multiple columns of first lamp zones Q1 and multiple columns of second lamp zones Q2 are alternately arranged, if the extension direction of the first signal line 101 is parallel to the first direction X, the extension direction of the second signal line 102 is parallel to the second direction Y, and a set of first signal lines 101 includes one first signal line 101, then multiple first signal lines 101 in the backplane 100 can correspond one-to-one with multiple rows of first lamp zones Q1, and can also correspond one-to-one with multiple rows of second lamp zones Q2. Multiple sets of second signal lines 102 can correspond one-to-one with multiple columns of first lamp zones Q1, and can also correspond one-to-one with multiple columns of second lamp zones Q2.

[0110] For example, any first signal line 101 in the backplane 100 can be electrically connected to the first electrode of each first light-emitting part 200 in the corresponding row of first lamp areas Q1, and can also be electrically connected to the first electrode of each second light-emitting part 300 in the corresponding row of second lamp areas Q2. Here, the first electrode of each first light-emitting part 200 in the same first lamp area Q1, and the first electrode of the second light-emitting part 300 in the second lamp area Q2 adjacent to this first lamp area Q1 in the second direction Y, can be simultaneously electrically connected to the corresponding first signal line 101.

[0111] It should be noted that the wiring method and connection relationship of the second signal line 102 in the backplane 100 can refer to the corresponding content in the first possible wiring scenario above. It will not be repeated here.

[0112] A third possible wiring configuration is shown in Figure 9, which is a top view of the internal wiring of another backplane provided in an embodiment of this application. When multiple rows of first lamp zones Q1 and multiple rows of second lamp zones Q2 are alternately arranged, if the extension direction of the first signal line 101 is parallel to the first direction X, the extension direction of the second signal line 102 is parallel to the second direction Y, and a group of first signal lines 101 includes one first signal line 101, then multiple first signal lines 101 in the backplane 100 can correspond one-to-one with multiple rows of first lamp zones Q1, and can also correspond one-to-one with multiple rows of second lamp zones Q2. Multiple groups of second signal lines 102 can correspond one-to-one with multiple columns of lamp zones. Here, a column of lamp zones can include multiple first lamp zones Q1 and multiple second lamp zones Q2 alternately arranged in the second direction Y.

[0113] It should be noted that the wiring method and connection relationship of the first signal line 101 in the backplane 100 can refer to the corresponding content in the second possible wiring scenario described above; the wiring method and connection relationship of the second signal line 102 in the backplane 100 can refer to the corresponding content in the first possible wiring scenario described above. Further details will not be provided here.

[0114] The fourth possible wiring configuration is shown in Figure 10, which is a top view of another type of internal wiring of the backplane provided in this embodiment. When multiple rows of first lamp zones Q1 and multiple rows of second lamp zones Q2 are alternately arranged, if the extension direction of the first signal line 101 is parallel to the first direction X, the extension direction of the second signal line 102 is parallel to the second direction Y, and one set of first signal lines 101 includes two first signal lines 101, then multiple sets of first signal lines 101 can correspond one-to-one with multiple rows of first lamp zones Q1, and multiple sets of first signal lines 101 can also correspond one-to-one with multiple rows of second lamp zones Q2. Multiple sets of second signal lines 102 can correspond one-to-one with multiple columns of lamp zones. Here, a column of lamp zones can include multiple first lamp zones Q1 and multiple second lamp zones Q2 alternately arranged in the second direction Y.

[0115] It should be noted that the wiring method and connection relationship of the first signal line 101 in the backplane 100, as well as the wiring method and connection relationship of the second signal line 102 in the backplane 100, can refer to the corresponding content in the first possible wiring scenario described above. Further details will not be provided here.

[0116] The fifth possible wiring configuration is shown in Figure 11, which is a top view of the internal wiring of a backplane according to another embodiment of this application. When multiple rows of first lamp zones Q1 and multiple rows of second lamp zones Q2 are alternately arranged, if the extension direction of the first signal line 101 is parallel to the second direction Y, the extension direction of the second signal line 102 is parallel to the first direction X, and one set of first signal lines 101 includes two first signal lines 101, then multiple sets of first signal lines 101 can correspond one-to-one with multiple rows of first lamp zones Q1, and multiple sets of first signal lines 101 can also correspond one-to-one with multiple rows of second lamp zones Q2. Multiple sets of second signal lines 102 can correspond one-to-one with multiple rows of lamp zones. Here, a row of lamp zones can include multiple first lamp zones Q1 and multiple second lamp zones Q2 alternately arranged in the first direction X.

[0117] For example, two first signal lines in a set of first signal lines 101 are first signal line 101a and first signal line 101b. First signal line 101a in the set of first signal lines 101 can be electrically connected to the first electrode of each first light-emitting part 200 in a corresponding column of first lamp areas Q1; first signal line 101b in the set of first signal lines 101 can be electrically connected to the first electrode of each second light-emitting part 102 in a corresponding column of second lamp areas Q2. Here, the first electrode of each first light-emitting part 200 in the same first lamp area Q1 can be simultaneously electrically connected to a corresponding first signal line 101a. In this case, among the multiple first signal lines 101 in the backplate 100, every two adjacent first signal lines 101 can be divided into a set of first signal lines 101. That is, the multiple first signal lines 101a and multiple first signal lines 101b in the backplate 100 are arranged alternately in the first direction X.

[0118] Since the number of second signal lines 102 in a set of second signal lines 102 is equal to the sum of the number of first light-emitting parts 200 in a first lamp zone Q1 and the number of second light-emitting parts 300 in a second lamp zone Q2, this explanation will be based on the example of a first lamp zone Q1 including three first light-emitting parts 200, which are used to emit red light, green light, and blue light respectively, and the example of a second lamp zone Q2 including one second light-emitting part 300 for emitting white light. Therefore, a set of second signal lines 102 can include four second signal lines: second signal line 102R, second signal line 102G, second signal line 102B, and second signal line 102W.

[0119] Specifically, the second signal line 102R can correspond to the first light-emitting part 200 in the first lamp area Q1 that emits red light; the second signal line 102G can correspond to the first light-emitting part 200 in the first lamp area Q1 that emits green light; the second signal line 102B can correspond to the first light-emitting part 200 in the first lamp area Q1 that emits blue light; and the second signal line 102W can correspond to a second light-emitting part 300 in the second lamp area Q2.

[0120] Therefore, the second signal line 102R in a set of second signal lines 102 can be electrically connected to the second electrode of each first light-emitting part 200 emitting red light in the corresponding row of lights; the second signal line 102G in a set of second signal lines 102 can be electrically connected to the second electrode of each first light-emitting part 200 emitting green light in the corresponding row of lights; the second signal line 102B in a set of second signal lines 102 can be electrically connected to the second electrode of each first light-emitting part 200 emitting blue light in the corresponding row of lights; and the second signal line 102W in a set of second signal lines 102 can be electrically connected to the second electrode of each second light-emitting part 300 in the corresponding row of lights. In this case, since the second signal lines 102R, 102G, and 102B in a set of second signal lines 102 need to be connected to the three first light-emitting parts 200 in the same first light area Q1, the second signal lines 102R, 102G, and 102B in a set of second signal lines 102 are arranged continuously in the second direction Y.

[0121] A sixth possible wiring configuration is shown in Figure 12, which is a top view of the internal wiring of another backplane provided in another embodiment of this application. When multiple rows of first lamp zones Q1 and multiple rows of second lamp zones Q2 are alternately arranged, if the extension direction of the first signal line 101 is parallel to the second direction Y, the extension direction of the second signal line 102 is parallel to the first direction X, and a group of first signal lines 101 includes one first signal line 101, then multiple first signal lines 101 in the backplane 100 can correspond one-to-one with multiple rows of first lamp zones Q1, and also one-to-one with multiple rows of second lamp zones Q2. Multiple groups of second signal lines 102 can correspond one-to-one with multiple rows of lamp zones. Here, a row of lamp zones can include multiple first lamp zones Q1 and multiple second lamp zones Q2 alternately arranged in the first direction X.

[0122] For example, any first signal line 101 in the backplate 100 can be electrically connected to the first electrode of each first light-emitting part 200 in a corresponding column of first lamp areas Q1, and can also be electrically connected to the first electrode of each second light-emitting part 300 in a corresponding column of second lamp areas Q2. Here, the first electrode of each first light-emitting part 200 in the same first lamp area Q1, and the first electrode of the second light-emitting part 300 in the second lamp area Q2 adjacent to this first lamp area Q1 in the first direction, can be simultaneously electrically connected to a corresponding first signal line 101.

[0123] It should be noted that the wiring method and connection relationship of the second signal line 102 in the backplane 100 can be referred to the corresponding content in the fifth possible wiring scenario above. It will not be repeated here.

[0124] Secondly, in the case where only a plurality of light-emitting lamp areas Q3 are present on one side of the backplate 100, as shown in FIG13, FIG13 is a top view of the internal wiring of another backplate provided in another embodiment of the present application, wherein the backplate 100 integrates a plurality of first signal lines 101 and a plurality of sets of second signal lines 102. Here, the extension direction of the first signal lines 101 may intersect with the extension direction of the second signal lines 102.

[0125] Among them, a first signal line 101 can be electrically connected to the first electrode of each light-emitting part in a row of light-emitting lamp areas Q3 arranged along the extension direction of the first signal line; a group of second signal lines 102 includes multiple second signal lines 102, and the multiple second signal lines 102 correspond one-to-one with multiple light-emitting parts in the same light-emitting lamp area Q3, and a second signal line 102 is electrically connected to the second electrode of each corresponding light-emitting part in a row of light-emitting lamp areas Q3 arranged along the extension direction of the second signal line 102.

[0126] For example, as shown in FIG13, when the extension direction of the first signal line 101 is parallel to the first direction X and the extension direction of the second signal line 102 is parallel to the second direction Y, the multiple first signal lines 101 in the back plate 100 can correspond one-to-one with multiple rows of light-emitting lamp areas Q3, and the multiple sets of second signal lines 102 in the back plate 100 can correspond one-to-one with multiple columns of light-emitting lamp areas Q3.

[0127] Specifically, for any one of the first signal lines 101 in the backplate 100, the first signal line 101 can be electrically connected to the first electrode of each of the first light-emitting parts 200 and the first electrode of each of the second light-emitting parts 300 in the corresponding row of light-emitting areas Q3.

[0128] For any group of second signal lines 102 in the backplate 100, the number of second signal lines in this group of second signal lines 102 is equal to the sum of the number of first light-emitting parts 200 and second light-emitting parts 300 located in the same light-emitting area Q3. Here, we will take as an example that a light-emitting area Q3 includes three first light-emitting parts 200 and one second light-emitting part 300, and the three first light-emitting parts 200 are used to emit red light, green light and blue light respectively, and the one second light-emitting part 300 is used to emit white light. Then, a group of second signal lines 102 can include four second signal lines, which are: second signal line 102R, second signal line 102G, second signal line 102B and second signal line 102W.

[0129] Specifically, the second signal line 102R can correspond to the first light-emitting part 200 in the light-emitting lamp area Q3 that emits red light; the second signal line 102G can correspond to the first light-emitting part 200 in the light-emitting lamp area Q3 that emits green light; the second signal line 102B can correspond to the first light-emitting part 200 in the light-emitting lamp area Q3 that emits blue light; and the second signal line 102W can correspond to the second light-emitting part 300 in the light-emitting lamp area Q3 that emits white light.

[0130] Therefore, the second signal line 102R in a set of second signal lines 102 can be electrically connected to the second electrode of each first light-emitting part 200 emitting red light in the corresponding light-emitting lamp area Q3; the second signal line 102G in a set of second signal lines 102 can be electrically connected to the second electrode of each first light-emitting part 200 emitting green light in the corresponding row of light-emitting lamp areas Q3; the second signal line 102B in a set of second signal lines 102 can be electrically connected to the second electrode of each first light-emitting part 200 emitting blue light in the corresponding row of light-emitting lamp areas Q3; and the second signal line 102W in a set of second signal lines 102 can be electrically connected to the second electrode of each second light-emitting part 300 emitting white light in the corresponding row of light-emitting lamp areas Q3.

[0131] In this embodiment, please refer to FIG14, which is a schematic diagram of the driving principle of a backplane provided in this embodiment. Here, it is illustrated by the fact that the first electrode of the first light-emitting part 200 and the first electrode of the second light-emitting part 300 need to be connected to two different first signal lines 101, and the backplane 100 has multiple first lamp areas Q1 and multiple second lamp areas Q2 simultaneously. The first signal line 101 connected to the first electrode of the first light-emitting part 200 can be connected to the first driving part 401, and the second signal line 102 connected to the second electrode of the first light-emitting part 200 can be connected to the second driving part 402; the third signal line 101 connected to the first electrode of the second light-emitting part 300 can be connected to the third driving part 403, and the second signal line 102 connected to the second electrode of the second light-emitting part 300 can be connected to the fourth driving part 404.

[0132] Here, the first driving unit 401 and the second driving unit 402 can control the light emission state of the first light-emitting unit 200 in the display substrate 000; the third driving unit 403 and the fourth driving unit 404 can control the light emission state of the second light-emitting unit 300 in the display substrate 000.

[0133] It should be noted that the first drive unit 401 can typically be connected to multiple consecutively arranged first signal lines 101. For example, if the first drive unit 401 has 8 channels, the 8 consecutively arranged first signal lines 101 can be connected to the same first drive unit 401. Similarly, the second drive unit 401 can also be connected to multiple consecutively arranged second signal lines 101. The first drive unit 401 can be a row tube, and the second drive unit 402 can be a column tube. It should also be noted that the structure and function of the third drive unit 403 can be the same as the first drive unit 401, and the structure and function of the fourth drive unit 404 can be the same as the second drive unit 402. Further details will not be provided here.

[0134] It should also be noted that, through the row and column tubes, each of the first light-emitting parts 200 in the display substrate 000 can be kept in an off state while each of the second light-emitting parts 300 in the display substrate 000 is emitting light; alternatively, each of the second light-emitting parts 300 in the display substrate 000 can be kept in an off state while each of the first light-emitting parts 200 in the display substrate 000 is emitting light; or, each of the first light-emitting parts 200 and each of the second light-emitting parts 300 in the display substrate 000 can be emitting light simultaneously. Therefore, the display substrate 000 can be periodically in a display state and an illumination state.

[0135] Optionally, as shown in Figures 7 to 13, the backplate 100 also integrates a plurality of first pad groups S10 that are electrically connected to a plurality of first light-emitting parts 200, and a plurality of second pad groups S20 that are electrically connected to a plurality of second light-emitting parts 300.

[0136] The first pad group S10 may include a first electrode pad S11 electrically connected to the first electrode of the first light-emitting part 200, and a second electrode pad S12 electrically connected to the second electrode of the first light-emitting part 200. The second pad group S20 may include a third electrode pad S21 electrically connected to the first electrode of the second light-emitting part 300, and a fourth electrode pad S22 electrically connected to the second electrode of the second light-emitting part 300.

[0137] Here, the same first signal line 101 in the backplane 100 can be electrically connected to multiple first electrode pads S11 and / or multiple third electrode pads S21. For example, when a group of first signal lines 101 in the backplane 100 includes two first signal lines, as shown in FIG7, the first electrode pads S11 connected to each first light-emitting part 200 in a row of first lamp areas Q1 can be simultaneously connected to the same first signal line 101a, and the third electrode pads S21 connected to each second light-emitting part 300 in a row of second lamp areas Q2 can be simultaneously connected to the same first signal line 101b. When a group of first signal lines 101 in the backplane 100 includes one first signal line, as shown in FIG8, the first electrode pads S11 connected to each first light-emitting part 200 in a row of first lamp areas Q1, and the third electrode pads S21 connected to each second light-emitting part 300 in a row of second lamp areas Q2, can be simultaneously connected to the same first signal line 101.

[0138] The same second signal line 102 in the backplane 100 can be electrically connected to multiple second electrode pads S12 or multiple fourth electrode pads S22. For example, in the case where a group of second signal lines 102 includes four second signal lines, the second electrode pads S12 connected to a row of first light-emitting parts 200 that emit red light can be simultaneously connected to the same second signal line 102R; the second electrode pads S12 connected to a row of first light-emitting parts 200 that emit green light can be simultaneously connected to the same second signal line 102G; the second electrode pads S12 connected to a row of first light-emitting parts 200 that emit blue light can be simultaneously connected to the same second signal line 102B; and the fourth electrode pads S22 connected to a row of second light-emitting parts 300 that emit white light can be simultaneously connected to the same second signal line 102W.

[0139] In this embodiment, the first signal lines 101 in the backplane 100 are arranged in the same layer, and the second signal lines 102 in the backplane 100 are arranged in the same layer. That is, multiple first signal lines 101 in the backplane 100 can be distributed in the same first conductive layer, and multiple second signal lines 102 in the backplane 100 can be distributed in the same second conductive layer. Furthermore, an insulating layer can be distributed between the first conductive layer and the second conductive layer in the backplane 100, thereby ensuring that the first signal lines 101 and the second signal lines 102 will not short-circuit at their intersections.

[0140] Optionally, each first electrode pad S11 and each third electrode pad S21 in the backplane 100 can be disposed in the same layer as the first signal line 101 and made of the same material. That is, the first conductive layer also includes multiple first electrode pads S11 and multiple third electrode pads S21. For example, since both the first electrode pads S11 and the third electrode pads S21 are connected to the corresponding first signal line 101, a portion of the first signal line 101 can be directly used as the first electrode pads S11 and the third electrode S21.

[0141] Similarly, each second electrode pad S12 and each fourth electrode pad S22 in the backplane 100 can also be disposed in the same layer as the first signal line 101 and made of the same material. That is, the first conductive layer also includes multiple second electrode pads S12 and multiple fourth electrode pads S22.

[0142] In this case, as shown in Figures 7, 8, 9, 10, 12, and 13, the first signal line 101 may have a first cutout groove U1 and a second cutout groove U2. The second electrode pad S12 may be distributed within the first cutout groove U1, and the third electrode pad S22 may be distributed within the second cutout groove U2.

[0143] In this way, by setting a first cutout groove U1 on the first signal line 101 and placing the second electrode pad S12 within the first cutout groove U1, it can be ensured that the second electrode pad S12 is insulated from the first signal line 101 through the first cutout groove U1. Similarly, by setting a second cutout groove U2 on the first signal line 101 and placing the fourth electrode pad S22 within the second cutout groove U2, it can be ensured that the fourth electrode pad S22 is insulated from the first signal line 101 through the second cutout groove U2.

[0144] It should be noted that, as shown in Figures 7, 8, 9, 10, and 12, when the back panel 100 has multiple first light areas Q1 and multiple second light areas Q2, the first hollow slot U1 and the second hollow slot U2 are separately arranged. As shown in Figure 13, when the back panel 100 only has multiple light-emitting areas Q3, the first hollow slot U1 and the second hollow slot U2 can be connected.

[0145] Optionally, to ensure that the second electrode pad S12 can be smoothly connected to the second signal line 102, the first conductive layer in the backplane 100 further includes a first adapter line Z1 connected to the second electrode pad S12. Furthermore, the insulating layer in the backplane 100 located between the first and second conductive layers has a first via V1, and the end of the first adapter line Z1 facing away from the second electrode pad S12 can be connected to the second signal line 102 in the second conductive layer through the first via V1.

[0146] Similarly, to ensure that the fourth electrode pad S22 can be smoothly connected to the second signal line 102, the first conductive layer in the backplane 100 also includes a second adapter line Z2 connected to the fourth electrode pad S22. Furthermore, the insulating layer in the backplane 100 located between the first and second conductive layers has a second via V2, and the end of the second adapter line Z2 facing away from the fourth electrode pad S22 can be connected to the second signal line 102 in the second conductive layer through the second via V2.

[0147] It should be noted that both the first light-emitting part 200 and the second light-emitting part 300 in the display substrate 000 can be LED chips. Here, the LED chip can be a standard-sized LED chip, a mini light-emitting diode (MLED) chip, or a micro LED (MicroLED) chip. This application does not limit this. In one possible implementation, each first light-emitting part 200 and each second light-emitting part 300 is individually configured. In another possible implementation, at least two first light-emitting parts 200 (e.g., three first light-emitting parts 200) belonging to a pixel group can be integrated into a single light-emitting chip, which emits red, green, and blue light; while each second light-emitting part 300 remains individually configured. In another possible implementation, at least two first light-emitting parts 200 (e.g., three first light-emitting parts 200) belonging to a pixel group and a second light-emitting part 300 can be integrated into a light-emitting chip for emitting red light, green light, blue light and white (or orange) light.

[0148] In summary, the display substrate provided in this application includes a back plate and a plurality of first light-emitting portions and second light-emitting portions located on one side of the back plate. When the display substrate is in a display state, it can display an image through the first light-emitting portions; when the display substrate is in an illumination state, it can provide good illumination through the second light-emitting portions or through both the first and second light-emitting portions. Therefore, during the virtual shooting of a target object on the light-emitting side of a display screen integrating this display substrate, the display screen can periodically display a background image and an illuminated image. During the display screen displaying an image, the shooting device can use a background image with the target object removed and the background image retained; during the display screen displaying an image, the shooting device can use a main image of the target object with the background removed and the main image retained. After subsequently stitching the background image and the main image together, the resulting target image containing both the target object and the background image displayed on the display screen has a better display effect, thereby effectively improving the shooting effect of the target object.

[0149] This application also provides a display module, which may include: a housing and a display substrate located on one side of the housing. Here, the display substrate may be the display substrate shown in the above embodiments.

[0150] Optionally, the display module can contain multiple display substrates, which can be arranged in a splicing manner on the same side of the housing. Here, each display substrate can be the display substrate shown in the above embodiments.

[0151] This application also provides a display screen, which may include spliced ​​display modules. Each display module can be the display module shown in the above embodiments.

[0152] This application also provides a shooting system capable of virtually shooting a target object. As shown in Figure 15, which is a schematic diagram of the structure of a shooting system provided in this application embodiment, the shooting system may include: a processing device 001, a shooting device 002, and at least one display screen 003. Here, the display screen 003 may be the display screen shown in the above embodiment.

[0153] During the virtual shooting of a target object using this shooting system, the target object can be positioned appropriately on the light-emitting side of the display screen 003. Based on the requirements of the virtual scene, the display screen 003 displays a corresponding background image. Then, the shooting device 002 simultaneously captures images of the display screen 003 and the target object positioned on the light-emitting side of the display screen 003, thus obtaining an image of the target object within a specific virtual scene. During the shooting process, the various display substrates 000 in the display screen 003 can alternately switch between display and illumination states.

[0154] Therefore, the imaging device 002 in the imaging system can be configured to: capture images of a target object located on the light-emitting side of the display screen 003 to obtain a first image and a second image. The first image is an image captured by the imaging device 002 when each display substrate 000 in the display screen 003 is in a display state, and the second image is an image captured by the imaging device 002 when each display substrate 000 in the display screen 003 is in an illuminated state.

[0155] In this application, after acquiring the first image and the second image, the shooting device 002 can send the first image and the second image to the processing device 001, so that the processing device can acquire a target image containing the target object and the background image displayed on the screen based on the first image and the second image.

[0156] It should be noted that when each display substrate 000 in the display screen 003 is in the display state, at least some of the first light-emitting parts 200 in each display substrate 000 can emit light, while each of the second light-emitting parts 300 in each display substrate 000 can be in the off state. Therefore, the display screen 003 can display a background image with a better effect. Consequently, the first image captured by the imaging device 002 will include a background image with a better display effect, but will also include target objects with color deviations.

[0157] When each display substrate 000 in the display screen 003 is illuminated, each second light-emitting part 300 in each display substrate 000 can emit light. Therefore, the display screen 003 can have a better supplementary lighting effect. For this reason, the second image captured by the imaging device 002 will include the target object with small color differences, but will not include the background image.

[0158] Subsequently, after receiving the first and second images, the processing device can process them to obtain a target image that includes the target object with minimal color differences and the background image displayed on the screen. This effectively improves the quality of the target image, thus ensuring better results in virtual photography of the target object.

[0159] Optionally, the processing device 001 can be configured to: crop the first image according to the position information of the target object in the first image to obtain a background image with the target object removed but the background image retained; crop the second image according to the position information of the target object in the second image to obtain a main image with the background image removed but the target object retained; and stitch the background image and the main image together to obtain the target image.

[0160] For example, after acquiring the first image, the processing device 001 can use an image recognition algorithm to obtain the outline of the target object in the first image, thereby obtaining the position information of the target object in the first image. Then, the processing device can use an image cropping algorithm to crop the first image, thereby obtaining a background image with the target object removed but the background image retained.

[0161] Similarly, after acquiring the second image, the processing device 001 can also use an image recognition algorithm to obtain the outline of the target object in the second image, thereby obtaining the position information of the target object in the second image. Then, the processing device can use an image cropping algorithm to crop the second image, thereby obtaining a main image with the background removed but retaining the target object.

[0162] In this way, the subsequent processing device 001 can stitch the background image and the main image together to obtain a target image that includes the target object with small color differences and the background image displayed on the screen.

[0163] In this embodiment of the application, during the virtual shooting of the target object, the display screen 003 can periodically display a background image and a supplementary lighting image. The background image is the image displayed when each display substrate in the display screen is in display mode; the supplementary lighting image is the image displayed when each display substrate in the display screen is in illumination mode.

[0164] For example, the processing device 001 can send video source data to the display screen 003, enabling the display screen 003 to display a video stream based on the video source data. The video stream includes multiple alternating background frames and multiple frames of supplementary lighting. That is, after the display screen 003 displays one frame of background image, the next frame needs to display the supplementary lighting image; after the display screen 003 displays one frame of supplementary lighting image, the next frame needs to display the background image.

[0165] In this application, the display screen 003 displays the background image at a frequency greater than or equal to 30Hz, and also displays the supplementary light image at a frequency greater than or equal to 30Hz. Thus, the display screen 003 can display greater than or equal to 30 frames of the background image per second. Therefore, even if the difference between the background image and the supplementary light image is significant, and the background image and the supplementary light image are displayed alternately, the user is unlikely to notice excessive image jumps in the display screen 003.

Furthermore, it is understood that when an element or layer is referred to as being "on" another element or layer, it can be directly on the other element, or there may be intermediate layers.
