[0003] However, the punching on the display screen will make the through hole part unable to normally display information. For example, a black screen or dark color stripes will appear at the through hole, which reduces the display effect of the display screen. SUMMARY

[0025] For those skilled in the art to better understand the technical solutions of the present application, the exemplary embodiments of the present application are described below in conjunction with the drawings, which include various details of the embodiments of the present application to help understanding, and should be considered only as exemplary. Therefore, those skilled in the art should realize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. Also, for the sake of clarity and conciseness, the description below omits the description of well-known functions and structures.

[0026] In the case of no conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0027] As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items. The terms used herein are only used to describe specific embodiments and are not intended to limit the present application. As used herein, the singular forms "a" and "the" are also intended to include the plural forms unless the context clearly indicates otherwise. It will also be understood that the terms "comprise" and / or "consist of", when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and / or components but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof. The terms "connected" or "coupled" and / or similar terms are not limited to a physical or mechanical connection or linkage to either another part or device and can also include an electrical connection directly or indirectly, whether or not it is a wired or wireless electrical connection.

[0028] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present application, and will not be interpreted in an overly formal or overly strict sense unless expressly so defined herein.

[0029] In order to avoid the influence of modules such as cameras on the appearance of products, the camera can be arranged on the back side (the side away from the light-emitting surface) of the display screen in a terminal such as a mobile phone, i.e., the product appearance consistency is achieved by using an "under-screen camera".

[0030] A display screen is punched at a position where the "under-screen camera" is located to form a light transmission area, which allows light to pass through and is used for camera imaging. Since the display screen at the light transmission area is excavated, the light transmission area cannot display.

[0031] The light transmission area can include only one through hole or multiple small holes, and the area of the light transmission area is matched with the area of the "under-screen camera". For example, the area of the light transmission area is equal to the area of the under-screen camera.

[0032] In some related technologies, the light transmission area includes only one through hole. For example, Figure 1 A display effect schematic diagram of a display screen in a related technical solution is shown. Referring to Figure 1 , the light transmission area 110 in the display screen 100 is a "large hole", which causes the light transmission area 110 to display as a black screen.

[0033] In another related technology, the light transmission area includes multiple through holes. For example, Figure 2 A display effect schematic diagram of a display screen in a related technical solution is shown. Referring to Figure 2 , the light transmission area 210 in the display screen 200 includes multiple through holes 211.

[0034] Although the size of the through hole 211 is small, since the positions of the through holes 211 in the light transmission area 210 cannot be truly displayed, multiple dark stripes are still formed in the light transmission area 210, which reduces the user experience.

[0035] To at least solve the above problems, the present application provides a display screen, a terminal and a display method, which not only enable the display screen to display complete images or information, but also enable different functional devices arranged under the display screen to realize their corresponding functions (for example, realize image acquisition function, etc.), thereby improving the user experience.

[0036] Figure 3 A cross-sectional structure schematic diagram of a display screen provided by an embodiment of the present application is shown. As Figure 3 shown, the display screen in the embodiment of the present application has a light exit surface 310, and a through hole 320 is formed through the display screen on the light exit surface 310; the display screen further includes a first display unit at the light exit surface 310 and a second display unit at the side wall of the through hole 320.

[0037] The first display unit and the second display unit can be a one-sided screen (for example, a flexible screen or a rigid screen, etc.), or multiple independent display components (for example, Figure 3 multiple first display units 311 and multiple second display units 321) as shown, and the present application does not limit this.

[0038] The second display units are configured to emit light to the opening of the through hole 320 on the light emitting surface 310.

[0039] It should be noted that the display screen is a device for displaying images, which includes a plurality of display units, each of which is a structure capable of independently emitting display light and is used to display a "point" in an image, for example, each display unit is used to display a pixel or a sub-pixel in an image.

[0040] The light emitting surface 310 (the plane shown by the dashed line in the figure) is a main surface of the display screen, which is used for light emission for a user to view "front", and the opposite side of the light emitting surface 310 is the "back" of the display screen. Figure 3

[0041] In some embodiments, in order to protect the display screen, a glass cover plate can be further provided outside the light emitting surface 310, which is used to protect each display unit in the display screen from being damaged by external force.

[0042] The light emitting surface 310 of the display screen is provided with a plurality of first display units 311, which directly emit display light from the light emitting surface 310. At the same time, one end of the through hole 320 is opened on the light emitting surface 310, so that the light emitting surface 310 has no first display unit 311 at the opening position.

[0043] The image acquisition unit or the sensing unit for sensing light signals can be provided at the back side of the through hole 320, and the through hole 320 is used for the incident light to pass through. It should be understood that the function of the through hole 320 is not limited to the incident light passing through, and other functions not mentioned herein are also within the protection scope of the present application, which will not be described here.

[0044] Referring to Figure 3 The plurality of second display units 321 provided at the side wall of the through hole 320 emit light to the opening on the light emitting surface 310, so that the corresponding opening position of the light emitting surface 310 also has light emission, so that the display screen can perform complete image display.

[0045] In the production process of the display screen, the light emitting direction of each second display unit 321 can be adjusted according to the size of the opening of the through hole 320 on the light emitting surface 310, so that the light emitted by the plurality of second display units 321 in the produced display screen can completely cover the opening area of the through hole 320 on the light emitting surface 310, thereby ensuring that the display screen can perform complete image display.

[0046] ​In the embodiment, the through hole 320 is formed on the light emitting surface 310 of the display screen, and the second display units 321 are arranged on the side wall of the through hole 320. The second display units 321 can emit light from the side wall to the opening of the through hole 320 on the light emitting surface 310, and cooperate with the first display units 311 on the light emitting surface 310 to emit light to the light emitting side, so that the display screen can display images or information completely, and the through hole area can achieve better display effect.

[0047] In some example embodiments, Figure 4 FIG. 1 shows a structural diagram of a through hole of a display screen according to an embodiment of the present application.

[0048] As Figure 4 shown in the two-dimensional image, the display screen 300 has the through hole 320. In the three-dimensional image, it can be known that the area of the through hole 320 gradually increases in the direction from the back side of the display screen to the light emitting surface 310.

[0049] In the three-dimensional image, the through hole 320 is a funnel-shaped hole with a large opening area in the direction of the light emitting surface 310 and a small opening 330 area in the direction of the back side of the display screen. The light emitted by the second display units (not shown in the figure) arranged on the side wall of the through hole 320 can be more easily projected to the opening on the light emitting surface 310.

[0050] In some embodiments, the through hole 320 can also be a columnar hole, as long as the light emitted by the second display units arranged on the side wall of the through hole 320 can be transmitted to the opening on the light emitting surface 310.

[0051] It should be noted that there is no display unit on the plane where the back side of the display screen is located and the plane where the light emitting surface 310 is located, so that the image acquisition unit or the sensing unit arranged on the back side of the through hole 320 can collect light through the through hole 320.

[0052] In some example embodiments, the side wall surface of the through hole 320 is a rotational surface.

[0053] The rotational surface is a surface generated by rotating a planar curve (for example, a straight line, a concave curve or a convex curve, etc.) around a fixed straight line (for example, the central axis of the through hole 320) on the plane where the planar curve is located. The rotational surface is a smooth surface, so as to facilitate actual material processing and processing.

[0054] For example, Figure 5 FIG. 2 shows a three-dimensional structural diagram of the side wall of the through hole of the display screen according to an embodiment of the present application. As Figure 5As shown, the side wall surface of the through hole is a curved surface generated based on a straight line rotating around the central axis of the through hole for one round, that is, a conical funnel-shaped curved surface.

[0055] Figure 6 A three-dimensional structure diagram of a side wall of a through hole of a display screen is shown. Figure 6 As shown, the side wall surface of the through hole is a curved surface generated based on a convex curve rotating around the central axis of the through hole for one round. The convex curve is a curve protruding towards the inside of the through hole. The curvature of the curve can be set based on the use requirement, which is not limited in the present application.

[0056] Figure 7 A three-dimensional structure diagram of a side wall of a through hole of a display screen is shown. Figure 7 As shown, the side wall surface of the through hole is a curved surface generated based on a concave curve rotating around the central axis of the through hole for one round. The concave curve is a curve recessed towards the inside of the through hole. The curvature of the curve can be set based on the use requirement, which is not limited in the present application.

[0057] In the three-dimensional structures of the side walls of the three through holes shown, Figures 5 to 7 if the heights of the three through holes are the same, the side wall area of the through hole in Figure 5 is the smallest. Correspondingly, the least amount of display units is used in manufacturing the through hole; and the angle difficulty of setting the second display unit at each point on the side wall of Figure 5 is relatively small; in the production process, the bending angles corresponding to the A point (or the B point) and the C point (or the D point) are relatively high in requirement for the production process, compared with the other two cross sections.

[0058] Figure 6 The side wall area of the through hole in Figure 7 is increased, compared with Figure 5 , and the amount of display units used in manufacturing the through hole is also increased correspondingly; and the angle difficulty of setting the second display unit at each point on the side wall of Figure 6 and Figure 7 is relatively large.

[0059] In the production process, compared with Figure 5 , the bending angles corresponding to the A point (or the B point) and the C point (or the D point) in Figure 6 are small, and the requirement for the production process is low; Figure 7 the bending angles corresponding to the A point (or the B point) and the C point (or the D point) in are large, and the requirement for the production process is high.

[0060] Figures 5 to 7 Therefore, the three-dimensional structure of the side wall of the through hole can be selected in the production process according to the actual situation.The stereoscopic structure of the side wall of any one of the through holes in the display screen can be produced to meet the individual needs of users.

[0061] It should be noted that in the production process, the light emitting direction of each second display unit can be adjusted individually so that the light emitted by the second display unit reaches the corresponding position in the opening on the light emitting surface of the second display unit, so that the light emitted by all the second display units on the side wall of the through hole can completely cover the opening area on the light emitting surface, and the display screen can completely display the image.

[0062] For example, Figure 8 A schematic diagram of the light emitting direction of a second display unit of a display screen provided by an embodiment of the present application is shown. As shown in Figure 8 The light emitted by the A point on the side wall of the through hole is perpendicular to the A point. If the light emitting direction of the second display unit is not adjusted, the light emitted by the second display unit reaches the B point. If the light emitting direction of the second display unit is adjusted according to the use requirements in the production process, the light emitted by the second display unit reaches the C point, so as to meet the display requirements of the display screen.

[0063] By mapping the content displayed by the second display unit on the side wall of the through hole to the corresponding position in the opening on the light emitting surface, the corresponding display content can also be displayed at the opening, so that the user can watch the complete image when using the entire display screen to display the image, and the viewing effect of the user is improved.

[0064] In some exemplary embodiments, the display screen further comprises a support body. For example, Figure 9 A schematic diagram of the partial cross-sectional structure of the through hole of a display screen provided by an embodiment of the present application is shown. As shown in Figure 9 The through hole 320 is arranged in the support body 340, and the second display unit 321 is arranged on the surface of the side wall of the support body 340 corresponding to the through hole 320.

[0065] The gray arrow is used to represent the light entering the through hole 320 through the glass cover plate 312.

[0066] As an implementation manner of an embodiment of the present application, the main body of the display screen corresponding to the position of the through hole 320 can be composed of a support body 340 without display function, so that the through hole 320 is actually punched in the support body 340, and the side wall of the through hole 320 is the surface of the support body 340. A plurality of second display units 321 are arranged on the surface of the side wall of the support body 340 corresponding to the through hole 320 for display.

[0067] It should be understood that other portions of the display screen can also be provided with the support body 340, so that the plurality of first display units are arranged on the surface of the support body 340; or, other portions of the display screen except the through hole are not provided with the support body 340, and are directly provided with the structure having the first display unit.

[0068] In some embodiments, if there is no support body 340, the position where the image acquisition unit (or, the sensing unit, etc.) is arranged below the display screen can be directly formed into the through hole 320. For example, the display screen extends to the opening 330 in the back direction of the through hole 320.

[0069] Since the support body 340 does not have a display function or a light refraction function, etc., the second display unit 321 arranged at the side wall of the support body 340 corresponding to the through hole 320 can be displayed, so that the glass cover plate 312 on the light emitting surface can correspondingly receive the light emitted by each second display unit 321.

[0070] In some embodiments, the closed space formed by the glass cover plate 312, the plurality of second display units at the side wall of the through hole 320, and the image acquisition unit arranged on the back side of the display screen is a vacuum dust-free space, so as to reduce the possibility of light scattering in the space, thereby improving the image acquisition effect of the image acquisition unit. In other words, the light emitted by the plurality of second display units 321 is only transmitted to the glass cover plate 312 on the light emitting surface, and will not be transmitted to the light sensing device in the image acquisition unit. And the light entering the through hole 320 from the light emitting surface is also correspondingly received by the light sensing device in the image acquisition unit, so as to increase the light acquisition ratio of the image acquisition unit while enabling the display screen to completely display the image, thereby improving the display effect of the display screen.

[0071] In some exemplary embodiments, the first display unit 311 and the second display unit 321 can be display units of the same material or display units of different materials. For example, the first display unit 311 is a display unit realized based on a hard display board card, and the second display unit 321 is a display unit realized based on a flexible display board card.

[0072] For example, Figure 10 A structure schematic diagram of a through hole of a display screen provided by an embodiment of the present application is shown. As shown in Figure 10 The surface of the side wall of the through hole is covered with a flexible display film 322, and the second display unit (not shown in the figure) is located in the flexible display film 322.

[0073] The through hole 320 is arranged in the support body 340, and the image acquisition unit or the sensing unit, etc. can be arranged at the opening 330 in the back direction of the through hole 320.

[0074] The light emitting directions of the second display units in the flexible display film 322 are different. In order to make the content displayed by the second display units in the through hole 320 consistent with the content displayed by the display screen without the through hole, the light emitting directions of the second display units in the through hole 320 need to be controlled during the production of the display screen, so that the light emitted by the second display units in the through hole 320 just covers the opening area corresponding to the through hole 320.

[0075] For example, the light emitting direction of the second display unit located at the A1 point of the flexible display film 322 is from the A1 point to the A2 point on the light emitting surface 310; the light emitting direction of the second display unit located at the B1 point of the flexible display film 322 is from the B1 point to the B2 point on the light emitting surface 310; and so on, the light emitting direction of the second display unit located at the C1 point of the flexible display film 322 is from the C1 point to the C2 point on the light emitting surface 310.

[0076] For another example, the light emitting direction of the second display unit located at the E1 point of the flexible display film 322 is from the E1 point to the E2 point on the light emitting surface 310; the light emitting direction of the second display unit located at the F1 point of the flexible display film 322 is from the F1 point to the F2 point on the light emitting surface 310; and so on, the light emitting direction of the second display unit located at the D1 point of the flexible display film 322 is from the D1 point to the D2 point on the light emitting surface 310.

[0077] Through the adjustment of the light emitting directions described above, the light emitted by the flexible display film 322 can completely cover the opening on the light emitting surface 310, so that the display screen can completely display images and the display effect of the display screen is improved.

[0078] In some embodiments, during the production of the display screen, a flexible screen can also be used as the first display unit in the display screen. When the through hole is punched on the flexible screen, the flexible screen in the through hole part is not completely cut off, but is made into a funnel shape bending towards the inside of the through hole to form the through hole, so as to simplify the production of the through hole.

[0079] In some embodiments, the number of the through holes 320 can be one, and the area of the opening 330 in the back direction of the display screen is the same as the area of the light sensing device of the device arranged below the through hole 320. For example, the area of the opening 330 in the back direction of the display screen is the same as the area of the light inlet hole of the image acquisition unit arranged below the through hole 320, so that the image acquisition unit can perform light acquisition through the through hole 320.

[0080] In some exemplary embodiments, the number of the through holes is multiple; the display screen has a light transmission region, and the multiple through holes are uniformly distributed in the light transmission region of the display screen, so as to reduce the influence degree on the display effect of the display screen.

[0081] The light-transmitting region can be determined according to the area of the image acquisition unit or the sensing unit arranged according to the opening 330 in the back direction of the display screen, or can be determined according to the opening area on the light-emitting surface 310.

[0082] For example, Figure 11 A structure diagram of a through hole of a display screen is shown. As Figure 11 As shown, the flexible display film 322 is covered on the surface of the sidewall of each through hole, so as to display the content of the opening position of the through hole on the light-emitting surface 310 through the flexible display film 322.

[0083] In some embodiments, a glass cover plate is arranged on the light-emitting surface 310 corresponding to the light-transmitting region, and a photosensitive device of the image acquisition unit is arranged on the opening 330 in the back direction of the display screen corresponding to the light-transmitting region, so that the photosensitive device can acquire the required light through the plurality of through holes, and the image acquisition unit can perform shooting. At the same time, the flexible display film 322 arranged on the sidewall of each through hole displays the display content of the opening position of each through hole on the light-emitting surface 310, and the user can view the complete image from the direction of the light-emitting surface 310 of the display screen, thereby improving the user experience.

[0084] In some example embodiments, the second display unit includes a light-emitting sub-module; the light-emitting sub-module is configured to emit light to the opening of the through hole on the light-emitting surface.

[0085] The light-emitting sub-module can be a single structure. For example, the light-emitting sub-module is an organic light-emitting diode (OLED). The OLED is a current type organic light-emitting device, which emits light through the injection and recombination of carriers, and the luminous intensity is proportional to the injected current.

[0086] The second display unit constructed by the plurality of light-emitting sub-modules directly emits light to the opening of the through hole on the light-emitting surface, which is simple in structure and easy to implement.

[0087] In some example embodiments, the second display unit includes a light-emitting sub-module and a light guide structure. For example, Figure 12 A structure diagram of a second display unit of a display screen is shown. As Figure 12 As shown, the second display unit includes a light-emitting sub-module 3211 and a light guide structure 3212. The light-emitting sub-module 3211 and the light guide structure 3212 in the same horizontal plane are arranged on a substrate 3213.

[0088] The light guide structure 3212 is configured to guide the light emitted by the light-emitting sub-module 3211 to the opening of the through hole 320 on the light-emitting surface. SinceFigure 12 Each light-emitting sub-module 3211 and light guide structure 3212 in the display screen 320 is perpendicular to the substrate 3213, and thus the light emitted by each light-emitting sub-module 3211 is emitted perpendicular to the substrate 3213. This structure is simple, and the shape of the sidewall of the through hole 320 is less demanding, and is easy to implement.

[0089] In some embodiments, if the shape of the sidewall of the through hole is complex, the light-emitting sub-module 3211 can also emit light rays in different directions according to the angle between the light guide structure 3212 and the substrate 3213. For example, Figure 13 FIG. 6 shows a schematic diagram of a light guide structure of a display screen adjusting the direction of light emitted by a light-emitting sub-module according to an embodiment of the present application.

[0090] As shown in FIG. 6, each light guide structure 3212 can adjust the transmission direction of the light emitted by the light-emitting sub-module 3211 by changing the angle between the light guide structure 3212 and the substrate 3213. Figure 13

[0091] Each light guide structure 3212 includes two light guide columns.

[0092] For example, Figure 13 The angle between the first light guide structure 3212 on the left in FIG. 6 and the substrate 3213 is 90 degrees, and thus the light-emitting direction of the light-emitting sub-module 3211 built in the light guide structure 3212 is the "d1" direction.

[0093] Figure 13 The angle between the second light guide structure 3212 in FIG. 6 and the substrate 3213 is a rightward offset angle (for example, 15 degrees, etc.), and thus the light-emitting direction of the light-emitting sub-module 3211 built in the light guide structure 3212 is the "d2" direction.

[0094] Figure 13 The angle between the third light guide structure 3212 in FIG. 6 and the substrate 3213 is a rightward offset angle (for example, 60 degrees, etc.), and thus the light-emitting direction of the light-emitting sub-module 3211 built in the light guide structure 3212 is the "d3" direction.

[0095] In some exemplary embodiments, the light guide structure is a light guide column, and the sidewall of the light guide column is provided with a light-absorbing layer.

[0096] The light-absorbing layer is a layer with light-absorbing material, and the light-absorbing layer can absorb stray light rays refracted (or reflected) onto the sidewall of the light guide column through the light-absorbing material contained therein, thereby reducing the influence of the stray light rays on the display effect of the display screen, and the structure is simple and easy to implement.

[0097] In some exemplary embodiments, the light-emitting sub-module is a self-luminous module.

[0098] ​The self-luminous module can be an OLED or other display film block with a self-luminous function, and the present application does not limit this, as long as the module can realize the self-luminous function.

[0099] In some embodiments, the light-emitting sub-module can also be a liquid crystal display module or other display module based on the light filtering principle.

[0100] By using the self-luminous module as the light-emitting sub-module, the second display unit on the side wall of the through hole can independently emit light and display, which not only has a simple structure and is easy to implement, but also can improve the display efficiency of the second display unit, so that the display screen can quickly and accurately display a complete image.

[0101] Figure 14 A structure schematic diagram of a terminal provided by an embodiment of the present application is shown.

[0102] The terminal can be in the form of a mobile phone, a television, a tablet computer, a vehicle-mounted rearview mirror, a display device in a vehicle-mounted intelligent driving system, a vehicle-mounted display screen, virtual reality glasses, and a personal computer.

[0103] As shown in Figure 14 The terminal includes a display screen 410, which is any display screen provided by an embodiment of the present application, and an image acquisition unit 420 arranged at the position corresponding to the through hole 411 on the back side of the display screen 410.

[0104] The display screen 410 has a light-emitting surface, a plurality of first display units (not shown in the figure) are arranged at the light-emitting surface, a through hole 411 is formed on the light-emitting surface and penetrates the display screen 410, and a plurality of second display units (not shown in the figure) are arranged at the side wall of the through hole 411.

[0105] In some embodiments, the image acquisition unit 420 can be a camera or other unit with an image acquisition function, which can acquire the required light through the through hole 411. For example, the image acquisition unit 420 is a under-screen camera of the terminal.

[0106] According to the terminal in the present application, the image acquisition unit is arranged at the position corresponding to the through hole on the back side of the display screen, which not only enables the image acquisition unit to acquire the required incident light through the through hole, but also facilitates increasing the light amount of the image acquisition unit so as to acquire a high-definition image, and enables the light emitted by the plurality of second display units arranged at the side wall of the through hole to be incident on the opening on the light-emitting surface, so that the content displayed by the plurality of second display units is the same as the content to be displayed at the position corresponding to the through hole, thereby enabling the display screen to display an image completely and improving the display effect of the display screen.

[0107] Figure 15A flowchart of a display method provided by an embodiment of the present application is shown. The display method is applied to any display screen in the present application. For example, the display screen has a light-out surface, and a through hole is formed in the light-out surface and penetrates the display screen; the display screen further includes: a plurality of first display units located at the light-out surface; and a plurality of second display units located at a side wall of the through hole, for emitting light to an opening of the through hole on the light-out surface.

[0108] As shown in Figure 15 The display method includes the following steps.

[0109] In step S1501, a light-out surface image is determined according to the acquired image to be displayed.

[0110] The light-out surface image is an image that should be displayed on a plane of the opening of the through hole on the light-out surface.

[0111] For example, the image to be displayed is a whole image of a night scene with stars. Since the through hole is formed in the light-out surface and penetrates the display screen, the light-out surface image (i.e., an image to be displayed at the through hole, such as an image including two stars) needs to be determined according to the corresponding positional relationship between the through hole and the plane of the light-out surface.

[0112] The area of the light-out surface image is equal to the area of the opening plane of the through hole on the light-out surface. For example, if the area of the opening plane of the through hole on the light-out surface is the area of a circle with radius R, the area of the second sub-image is also the area of a circle with radius R.

[0113] For example, Figure 4 The circular area corresponding to the through hole 320 is the area of the light-out surface image. According to the positional relationship between the through hole 320 and the display screen 300, it can be seen that the through hole 320 is located in the upper half of the display screen 300 and is closer to the upper edge of the display screen 300. Therefore, based on the positional relationship between the through hole 320 and the display screen 300, the image to be displayed in the display screen 300 can be mapped, i.e., the light-out surface image to be displayed at the through hole 320 is the image in the circular area in the upper half of the image to be displayed and close to the upper edge of the image to be displayed.

[0114] In step S1502, the image content of the light-out surface image at the target position corresponding to each second display unit is determined.

[0115] The target position corresponding to each second display unit is the position of the opening of the through hole on the light-out surface reached by the light emitted by the second display unit.

[0116] After the light-out surface image is acquired, the image content of the light-out surface image at the target position corresponding to each second display unit can be determined according to Figure 10The light ray mapping relationship between each second display unit at the side wall of the through hole and the light emitting surface 310 determines the image content of the target position corresponding to each second display unit.

[0117] For example, if the light emitting surface image is an image displayed in a circular region with the distance between A2 and E2 as the diameter, it can be known that the light received at A2 is emitted by the second display unit at A1; in other words, the image content of the target position corresponding to the second display unit at A1 is the image content to be displayed at A2.

[0118] By analogy, the image content of the target position corresponding to the second display unit at E1 is the image content to be displayed at E2; the image content of the target position corresponding to the second display unit at B1 is the image content to be displayed at B2; the image content of the target position corresponding to the second display unit at F1 is the image content to be displayed at F2; and the image content of the target position corresponding to the second display unit at C1 (or D1) is the image content to be displayed at C2 (or D2).

[0119] It should be noted that the above correspondence relationship is used to determine the image content of the target position corresponding to each second display unit, which can accurately map the image to be displayed at each point in the opening plane of the through hole on the light emitting surface into each second display unit at the side wall of the through hole, so that the light emitting surface image (for example, an image including two stars) can be completely displayed in the opening plane of the through hole on the light emitting surface.

[0120] In step S1503, the display content of each second display unit is determined according to the image content of the target position corresponding to each second display unit.

[0121] In step S1503, the display content of each second display unit is determined according to the image content of the target position corresponding to each second display unit.

[0122] It should be noted that, since there is a certain angle relationship between the target position corresponding to the second display unit and the actual position of the second display unit, the image content of the target position corresponding to each second display unit needs to be mapped into the second display unit according to the angle relationship, so as to obtain the display content of each second display unit.

[0123] In the embodiment, the image that the through hole should display on the opening plane of the light emitting surface is determined through the position mapping relationship between the through hole and the display screen and the image of each part in the image to be displayed, that is, the light emitting surface image; further, based on the position of the opening of the through hole on the light emitting surface where the light emitted by the second display unit reaches, the corresponding target position of the second display unit is reversely mapped, and the part image in the light emitting surface image corresponding to the target position of the second display unit is determined, so that the display content to be displayed by each second display unit is accurately positioned, the display content of each second display unit can match the image content of the target position corresponding to each second display unit, the image of the part can be completely displayed at the through hole, and then the display screen can completely display the image to be displayed, so that the user can watch the complete image to be displayed through the display screen with the through hole, and the use experience of the user is improved.

For the convenience and brevity of description, detailed descriptions of known methods are omitted herein, and the specific working processes of the systems, modules and units described above can refer to the corresponding processes in the foregoing method embodiments, which will not be described here.
