Description

Display modules, displays, and electronic devices

[0001] This application claims priority to Chinese Patent Application No. 202411038806.X, filed on July 30, 2024, entitled “Display Module, Display Screen and Electronic Device”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of display technology, and in particular to a display module, a display screen, and an electronic device. Background Technology

[0003] Mobile phones, tablets, and other electronic devices have displays that show information. These devices have wide viewing angles, allowing users from different perspectives to see the images and / or text displayed on the screen. They also feature privacy screen functionality to prevent others from seeing the information displayed on the screen.

[0004] In related technologies, privacy screens are achieved by using a venetian blind film on the display screen. Specifically, the venetian blind film filters out light from wide viewing angles while retaining light from a direct viewing angle, preventing others at wide viewing angles from seeing the content displayed on the screen. However, while achieving privacy, the venetian blind film also reduces the display quality, thus diminishing the user's viewing experience. Summary of the Invention

[0005] This application provides a display module, a display screen, and an electronic device that, while achieving privacy protection, can improve the display effect of the display screen and enhance the user's viewing experience.

[0006] This application provides a display module including a pixel definition layer and a light-shielding layer. The pixel definition layer includes multiple pixel regions arranged in an array, each pixel region including at least one pixel. The light-shielding layer is located on the light-emitting side of the pixel definition layer and is used to block at least a portion of the light emitted by the pixels in each pixel region. The multiple pixel regions include a first pixel region, and the pixels in the first pixel region are first pixels. The first pixel has a first maximum emission angle and a second maximum emission angle. The first maximum emission angle is the maximum angle between the light emitted by the first pixel and emitted from a first side of the first pixel and the normal of the display module. The second maximum emission angle is the maximum angle between the light emitted by the first pixel and emitted from a second side of the first pixel and the normal. The first maximum emission angle is smaller than the second maximum emission angle, and the first side and the second side do not coincide.

[0007] A portion of the light emitted by each pixel in each pixel area enters the user's eyes, enabling the display function. Simultaneously, a light-shielding layer blocks a portion of the light emitted by each pixel area that falls within the viewing angle of people around the user, preventing them from receiving the light emitted by the pixels in that pixel area, thus achieving privacy protection. Furthermore, the light-shielding layer can also block light emitted by the first pixel within a corresponding angle range based on the first pixel's position in the display module, giving the first pixel a first maximum emission angle and a second maximum emission angle.

[0008] Because the first maximum emission angle is smaller than the second emission angle, the user's viewing angle along the first direction (i.e., the first side) is smaller than the user's viewing angle along the second direction (i.e., the second side). In other words, the range between the user's line of sight in the first direction and the normal to the display module is smaller than the range between the user's line of sight in the second direction and the normal. This results in the user receiving less light when viewing the display module along the first direction than when viewing it along the second direction. Therefore, by controlling the magnitudes of the first and second maximum emission angles of the first pixel based on its specific position within the display module, the emission angle of the first pixel can be matched to the user's viewing angle. This increases the amount of light received by the user and ensures that people nearby cannot see the displayed content, thereby improving the display effect of the display module and enhancing the user's viewing experience.

[0009] In some possible implementations, multiple pixel regions include a second pixel region, where the pixels in the second pixel region are second pixels. The maximum angle between the light rays emitted from and exiting from either side of the second pixel and the normal is the same. Since the user's eye is typically facing the center of the display module, designating the pixel region closest to the center of the display module as the second pixel region reduces the design complexity of the emission angle of pixels in the central region of the display module, thus improving the economic efficiency of the display module.

[0010] In some possible implementations, the display module includes a first region and a second region, wherein the distance between the first region and the edge of the display module is less than the distance between the second region and the edge of the display module. Specifically, at least one first pixel region is provided within the first region; the angle between the light rays emitted from the side of the first pixel region away from the second region and the normal is less than or equal to a first maximum emission angle, and the angle between the light rays emitted from the side of the first pixel region closer to the second region and the normal is less than or equal to a second maximum emission angle.

[0011] In this way, by setting the first pixel area in a first region closer to the edge of the display module, the first region can emit more light towards the user's eyes, increasing the brightness of the first region and improving the user's viewing experience, thereby enhancing the user's viewing experience of the display screen. Furthermore, it can reduce the light emitted by the first region towards people in the surrounding area, achieving privacy protection within the corresponding viewing angle.

[0012] In some possible implementations, at least one second pixel area is provided within the second region, and the angle between the light rays emitted from either side of the second pixel area closest to the first region and the normal is the same. Typically, the user's eye is directly facing the second region of the display module. Providing a second pixel area within the second region reduces the design complexity of the pixel emission angle in the second region, thus improving the economic efficiency of the display module.

[0013] In some possible implementations, there are multiple first regions, which are arranged around a second region. In this way, the first region is the edge region of the display module, and the second region is the center region of the display module. By setting a first pixel area within the first region, the brightness of the first region is made to be the same or almost the same as the brightness of the second region, thereby improving the display effect of the display module.

[0014] In some possible implementations, the light-shielding layer has multiple light-transmitting openings arranged in an array, with each light-transmitting opening corresponding to a different pixel area. Light emitted from the pixels in a pixel area is emitted out of the light-shielding layer through its corresponding light-transmitting opening.

[0015] In this way, by setting light-transmitting openings in the light-shielding layer, a portion of the light emitted by the pixels in each pixel area can enter the user's eyes, thus achieving the display function. Furthermore, by controlling the relative positions of the light-transmitting openings and the corresponding pixels in the pixel area in a direction perpendicular to the thickness direction of the display module, at least a portion of the pixel area is designated as the first pixel area.

[0016] In some possible implementations, the distance between the edge of the light-transmitting opening on the first side of the first pixel and the first pixel is a first distance, and the distance between the edge of the light-transmitting opening on the second side of the first pixel and the first pixel is a second distance, wherein the first distance is less than the second distance.

[0017] In this way, the first distance and the second distance are not equal, so that the light-shielding layer blocks the light emitted by the first pixel from different angle ranges on the first side and the second side respectively, so that the first pixel has a first maximum emission angle and a second maximum emission angle.

[0018] In some possible implementations, the light-shielding layer includes a first light-shielding layer and a second light-shielding layer. The first and second light-shielding layers are arranged along the thickness direction of the display module. The first light-shielding layer is located between the second light-shielding layer and the pixel definition layer. The orthographic projections of the first and second light-shielding layers onto a reference plane, which is the plane containing the length and width directions of the display module, overlap. The first light-shielding layer has a first light-transmitting space for light emitted from the pixels, and the second light-shielding layer has a second light-transmitting space for light emitted from the pixels. The second light-transmitting space forms a light-transmitting opening at one end along the thickness direction of the display module away from the pixel definition layer.

[0019] In this way, the first light-blocking layer blocks light within a wide viewing angle, preventing those nearby from seeing the light within that range. The second light-blocking layer blocks light within a narrow viewing angle, preventing those nearby from seeing the light within that range. Therefore, the combined effect of the first and second light-blocking layers blocks light within the viewing angle of those nearby, achieving privacy protection. Furthermore, the second light-blocking layer reduces the obstruction of light reaching the user's eyes, increasing the amount of light received by the user and thus increasing the perceived brightness, improving the user's viewing experience.

[0020] In some possible implementations, at least a portion of the first light-shielding layer and at least a portion of the second light-shielding layer are connected in the thickness direction of the display module. And / or, at least a portion of the first light-shielding layer and at least a portion of the second light-shielding layer are spaced apart in the thickness direction of the display module.

[0021] In this way, the first light-shielding layer can be spaced apart from the second light-shielding layer, or the first and second light-shielding layers can be partially or fully connected in the thickness direction of the display module, both of which can block a portion of the light emitted by each pixel, achieving privacy protection. Furthermore, the first pixel can be given a first maximum emission angle and a second maximum emission angle, increasing the amount of light received by the user's eyes and improving the user's viewing experience. When the first and second light-shielding layers are spaced apart, the manufacturing difficulty of the light-shielding layers can be reduced, which helps improve the economics of the display module.

[0022] In some possible implementations, the second light-transmitting space includes at least one through-hole penetrating the second light-shielding layer, or the second light-transmitting space has a notch in a direction perpendicular to the normal, allowing light emitted from the pixels in the pixel area that passes through the first light-shielding layer to pass through the second light-shielding layer, thereby achieving the display function. Furthermore, for the ground side (or bottom side) of the electronic device, there is no need to block light emitted from the first light-shielding layer in that direction, which reduces the design complexity of the second light-shielding layer.

[0023] In some possible implementations, the orthographic projection of the light-transmitting opening onto the reference plane is circular or rectangular; alternatively, the orthographic projection of the light-transmitting opening onto the reference plane includes two spaced-apart openings, each circular or rectangular in shape. The reference plane is the plane containing the length and width directions of the display module.

[0024] In this way, the light-transmitting openings allow a portion of the light emitted by the pixels in the pixel area to reach the user's eyes while ensuring that the second light-shielding layer blocks a portion of the light emitted by the pixels, achieving privacy protection. Furthermore, when the pixels in the pixel area are large in the direction perpendicular to the thickness direction of the display module, the orthographic projection of the light-transmitting openings on the reference plane includes two spaced-apart openings. This further increases the angular range of the light emitted by the pixels in the pixel area blocked by the second light-shielding layer, preventing light emitted by the pixels from falling within the viewing angle of people around the user from being unblocked, thus further enhancing the privacy protection effect.

[0025] In some possible implementations, the display module also includes a brightness enhancement layer, which comprises multiple brightness enhancement elements arranged in an array. Each brightness enhancement element corresponds to a multiple pixel area. Light emitted from the pixels in each pixel area passes through at least part of its corresponding brightness enhancement element, thereby increasing the amount of light passing through the light-transmitting opening and helping to further improve the display effect.

[0026] In some possible implementations, the orthographic projection of each brightener onto a reference plane at least partially overlaps with the orthographic projection of each pixel in the corresponding pixel region onto the reference plane, where the reference plane is the plane containing the length and width directions of the display module. This ensures that the brighteners converge the light emitted by the pixels in the pixel region, thus achieving brightening.

[0027] In some possible implementations, multiple brightness enhancers are arranged in a one-to-one correspondence with multiple light-transmitting openings. At least a portion of the orthographic projection of each brightness enhancer onto a reference plane is disposed within the orthographic projection of the corresponding light-transmitting opening onto the reference plane, where the reference plane is the plane containing the length and width directions of the display module. This ensures that light passing through the brightness enhancers can pass through the light-transmitting openings, thus achieving the display function.

[0028] In some possible implementations, the light-shielding layer includes a first light-shielding layer and a second light-shielding layer. The first light-shielding layer and the brightness enhancement layer are arranged in the same layer. The second light-shielding layer is arranged on the light-emitting side of the first light-shielding layer and on the light-emitting side of the brightness enhancement layer. The brightness enhancement layer causes the light emitted from the first light-shielding layer to be concentrated through the second light-shielding layer, increasing the amount of light passing through the second light-shielding layer and helping to improve the brightness of the privacy mode.

[0029] In some possible implementations, the pixel definition layer includes multiple pixel units arranged in an array. Each pixel unit includes a shared area and a pixel area. Both the shared area and the pixel area include at least one pixel for emitting light of the same color. The orthographic projection of the pixel area onto the reference plane does not overlap with the orthographic projection of the shared area onto the reference plane. The reference plane is the plane containing the length and width directions of the display module.

[0030] In this way, the display module has both a privacy mode and a sharing mode, and can switch between the two to meet different usage needs. In privacy mode, people around the user cannot see the content displayed on the module, thus fulfilling the privacy requirement. In sharing mode, people around the user can see the content displayed on the module, fulfilling the user's sharing needs.

[0031] In some possible implementations, in each pixel unit, at least a portion of the orthographic projection of the pixel region onto the reference plane lies inside the orthographic projection of the shared region onto the reference plane.

[0032] In some possible implementations, in each pixel unit, the shared area and the pixel area are arranged in a direction perpendicular to the thickness direction of the display module.

[0033] In some possible implementations, the display module has a privacy mode and a sharing mode. In privacy mode, pixels in the privacy area emit light, while pixels in the sharing area do not. In sharing mode, both pixels in the privacy area and pixels in the sharing area emit light, or pixels in the sharing area emit light while pixels in the privacy area do not.

[0034] In this way, by controlling the light emitted by pixels in the shared area and / or pixel area, the display module can switch between privacy mode and shared mode to achieve privacy display or shared display, thus meeting different needs.

[0035] In some possible implementations, all pixels in each pixel unit are electrically connected to the same pixel driving circuit. When pixels in the pixel area and the shared area are lit simultaneously, the current of the pixels in the pixel area can be reduced. This not only ensures that the brightness of the display module remains unchanged before and after the pixels in the shared area are lit, but also extends the lifespan of the pixels in the pixel area.

[0070] Figure 1 is a cross-sectional schematic diagram of a venetian blind privacy film in the related technology.

[0071] Referring to Figure 1, in related technologies, a venetian blind privacy film includes a reinforcing layer 101, a privacy layer 102, and two support layers 103. The privacy layer 102 is located between the two support layers 103, with one support layer 103 located between the reinforcing layer 101 and the privacy layer 102. The privacy layer 102 includes a planarization layer 104 and multiple arrayed privacy elements 105. The privacy elements 105 are used to block light from a wide viewing angle (as shown by α in Figure 1). The spacing between adjacent privacy elements 105 is very small (similar to a venetian blind structure), thus allowing only light within a small angle range, such as the 20° range shown in Figure 1, to pass through, achieving a privacy effect. Therefore, by filtering out light from a wide viewing angle and retaining light from a normal viewing angle, other people at a wide viewing angle cannot see the content displayed on the screen.

[0072] However, while privacy films on blinds provide privacy, they also reduce the display quality. For example, when a user's eyes are in the center of the screen, the brightness of the edge areas is lower than that of the center, making the edge areas appear darker and reducing the user's viewing experience. Therefore, how to achieve privacy while maintaining display quality is a pressing issue that needs to be addressed.

[0073] In view of this, embodiments of this application provide a display module 300, a display screen 200, and an electronic device. The display module 300 uses a light-shielding layer 60 to block a portion of the light emitted by pixels 34 of pixel area 33 within the viewing angle of people around the user, preventing people in the vicinity from seeing the information displayed on the display screen 200 and achieving privacy display. Furthermore, the light-shielding layer 60 can also block light emitted by pixels 34 of pixel area 33 within a corresponding angle range depending on the different positions of pixel area 33 in the display module 300. This results in the display module 300 having a first pixel area 33A, and the first pixel 34A of the first pixel area 33A having a first maximum emission angle M1 and a second maximum emission angle M2. The emission angle of the first pixel 34A matches the user's viewing angle, allowing the user to receive more light, improving the display effect of the display module 300, and enhancing the user's viewing experience.

[0074] This application provides an electronic device, which may include, but is not limited to, a mobile phone, tablet computer, laptop computer, ultra-mobile personal computer (UMPC), handheld computer, walkie-talkie, netbook, point of sale (POS) machine, personal digital assistant (PDA), wearable device, or any other device with a display screen 200. The following description uses a mobile phone as an example.

[0075] Figure 2 is a schematic diagram of an electronic device provided in an embodiment of this application.

[0076] Referring to Figure 2, the electronic device includes a housing 100 and a display screen 200, with the display screen 200 connected to the housing 100. The housing 100 may include a mid-frame and a back cover. The back cover and the display screen 200 are located on the image side opposite to the mid-frame and are respectively connected to the mid-frame. The back cover and the mid-frame can form a receiving cavity for accommodating a battery, a motherboard, and a camera module.

[0078] For example, referring to FIG3, the display screen 200 may include a display module 300 and a surface module 400, wherein the surface module 400 is disposed on the display side of the display module 300.

[0079] The specific type of display screen 200 is not limited here. In some embodiments, the display screen 200 can be an OLED (organic light-emitting diode) display screen, in which case the display module 300 in the display screen 200 is an OLED display module. In other embodiments, the display screen 200 can be an LCD (liquid crystal display) display screen, in which case the display module 300 in the display screen 200 is an LCD display module. In still other embodiments, the display screen 200 can be a quantum dot light-emitting diode (QLED) display screen, in which case the display module 300 in the display screen 200 is a QLED display module. The following description uses an OLED display screen as an example.

[0080] The specific structure of the surface module 400 is not limited here. In some embodiments, referring to FIG3, the surface module 400 may include a transparent protective layer 410 and an opaque layer 420. The opaque layer 420 is located between the transparent protective layer 410 and the display module 300. The display screen 200 includes a display area and a bezel area (or bezel area) surrounding the display area. The opaque layer 420 is located inside the bezel area and is used to shield the devices within the bezel area to improve the aesthetics of the electronic device. The opaque layer 420 is formed of an opaque material, such as opaque ink. The transparent protective layer 410 is used to protect the display module 300, and the light-transmitting layer is made of a light-transmitting material, such as glass.

[0081] In some other embodiments, the surface module 400 may also include a polarizer 81, a transparent protective layer 410, and an opaque layer 420, with the polarizer 81 located between the transparent protective layer 410 and the display module 300, and the opaque layer 420 located between the polarizer 81 and the transparent protective layer 410. In still other embodiments, the surface module may also include a touch layer 50, a transparent protective layer 410, and an opaque layer 420, with the touch layer 50 located between the transparent protective layer 410 and the display module 300, and the opaque layer 420 located between the touch layer 50 and the transparent protective layer 410, the touch layer 50 being used to enable the display screen 200 to have display functionality.

[0082] The display module 300 provided in this application embodiment will be described in detail below with reference to specific embodiments.

[0083] Example 1

[0084] Figure 4 is a cross-sectional schematic diagram of the first display module provided in the embodiment of this application. Figure 4 is used to illustrate the emission angle of pixels 34 in different regions of the display module 300, and does not imply that the specific structure of the display module 300 is as shown in Figure 4.

[0085] Referring to Figure 4, the display module 300 may include a substrate 10, a circuit layer 20, a pixel definition layer 30, an encapsulation layer 40, a light-shielding layer 60, and a surface base layer 80 stacked together. The pixel definition layer 30 has multiple pixels 34 arranged in an array. The circuit layer 20 controls the light emission of the pixels 34, enabling the display module 300 to display images, text, and other information. The light-shielding layer 60 blocks light emitted from the pixel definition layer 30 that falls within the viewing angle of people around the user, achieving privacy protection.

[0086] The specific structure of the surface base layer 80 is not limited here. For example, referring to Figure 4, the surface base layer 80 may include a polarizer 81 and a cover plate 82. The polarizer 81 is located between the cover plate 82 and the light-shielding layer 60, which can further improve the display effect.

[0087] Referring again to Figure 4, the display module 300 may further include a planarization layer 90, and a light-shielding layer 60 may be located inside the planarization layer 90. The planarization layer 90 is used to planarize the light-shielding layer 60.

[0088] In some possible implementations, as shown in Figure 4, the display module 300 may also include a touch layer 50 located between the light-shielding layer 60 and the encapsulation layer 40, thereby enabling the display module 300 to have touch functionality.

[0089] It should be noted that the structure of the display module 300 is not limited to that shown in Figure 4, and can also be other structures, such as removing the touch layer 50 in Figure 4.

[0090] Figure 5 is a top view of the first type of pixel definition layer and second light-shielding layer cooperation provided in an embodiment of this application, and Figure 6 is a top view of the second type of pixel definition layer and second light-shielding layer cooperation provided in an embodiment of this application. It should be noted that Figures 5 and 6 are only used to exemplify two distribution trends of the pixel definition layer and second light-shielding layer cooperation. The number, position, and arrangement of pixel areas are not limited to those shown in Figures 5 and 6.

[0091] Referring to Figure 5, the pixel definition layer 30 includes a plurality of pixel units 31 arranged in an array. Each pixel unit 31 may include a first pixel unit, a second pixel unit, and a third pixel unit, which are used to emit different colors of light. For example, the first pixel unit emits red light, the second pixel unit emits green light, and the third pixel unit emits blue light. Alternatively, the plurality of pixel units 31 may be composed of pixel units 31 that emit at least four different colors of light; for example, the plurality of pixel units 31 may also include pixel units 31 that emit red, green, blue, and white light.

[0092] The arrangement of the multiple pixel units 31 is not limited here. In some embodiments, as shown in FIG5, the multiple pixel units 31 are arranged in a triangular arrangement. In other embodiments, as shown in FIG6, the multiple pixel units 31 can also be arranged in a square arrangement. In still other embodiments, the multiple pixel units 31 can also be arranged in a diamond arrangement.

[0093] Referring to Figure 5, each pixel unit 31 includes a shared area 32 and a pixel area 33 (or privacy area). Both the shared area 32 and the pixel area 33 include at least one pixel 34 for emitting light of the same color. For example, the shared area 32 includes two pixels 34 and the pixel area 33 includes one pixel 34. Of course, the number of pixels 34 in the shared area 32 can be less than or more than two, and the number of pixels 34 in the pixel area 33 can also be more than one. The pixels 34 of the shared area 32 and the pixels 34 of the pixel area 33 can be formed in different shapes. For example, as shown in Figure 5, the pixels 34 of the shared area 32 are formed as a ring structure surrounding the pixel area 33. The orthographic projection of the pixel area 33 onto the reference plane does not overlap with the orthographic projection of the shared area 32 onto the reference plane. For example, as shown in Figure 5, the orthographic projection of the pixel area 33 onto the reference plane can be circular, and the orthographic projection of the shared area 32 onto the reference plane can be annular. The circular and annular projections do not overlap. The reference plane is the plane containing the length direction X and the width direction Y of the display module 300.

[0094] Each pixel unit 31 is composed of a shared area 32 and a pixel area 33, enabling the display module 300 to have both a privacy mode and a sharing mode. In privacy mode, pixels 34 in pixel area 33 emit light, while pixels 34 in shared area 32 do not. In privacy mode, people around the user cannot see the content displayed on the display module 300, thus satisfying privacy requirements. In sharing mode, both pixels 34 in pixel area 33 and pixels 34 in shared area 32 can emit light, or pixels 34 in shared area 32 can emit light while pixels 34 in pixel area 33 do not. In sharing mode, people around the user can see the content displayed on the display module 300, satisfying the user's sharing needs.

[0095] For example, when the display module 300 is in sharing mode, both pixels 34 in pixel area 33 and pixels 34 in sharing area 32 can emit light, which can increase the brightness of the display module 300, maintain the resolution, and help to further improve the display effect. Alternatively, in some embodiments, when the display module 300 is in sharing mode, pixels 34 in pixel area 33 do not emit light, while pixels 34 in sharing area 32 emit light, which can also allow people in the vicinity to see the displayed content, thus meeting the sharing requirements.

[0096] It should be noted that the display module 300 is usually in privacy mode, and the sharing mode is enabled as needed.

[0097] Referring to Figure 4, a light-shielding layer 60 is disposed on the light-emitting side of the pixel definition layer 30. The light-shielding layer 60 blocks at least a portion of the light emitted by the pixels 34 of each pixel area 33, controlling the emission angle of the pixels 34 within a corresponding range. This allows a portion of the light emitted by the pixels 34 of each pixel area 33 to enter the user's eyes, thus achieving the display function. Simultaneously, the light-shielding layer 60 also blocks a portion of the light emitted by the pixels 34 of each pixel area 33 that falls within the viewing angle of people around the user, preventing them from receiving the light emitted by the pixels 34 of the pixel area 33, thus achieving a privacy screen display.

[0098] Referring to Figure 5, there are multiple pixel units 31, indicating that there are multiple pixel regions 33. Under the shading effect of the light-shielding layer 60, as shown in Figure 4, the multiple pixel regions 33 may include a first pixel region 33A and a second pixel region 33B. Pixel 34 of the first pixel region 33A is called the first pixel 34A, and pixel 34 of the second pixel region 33B is called the second pixel 34B. There may be one or more first pixel regions 33A, and one or more second pixel regions 33B. It should be noted that, in addition to being composed of first pixel regions 33A and second pixel regions 33B, in some embodiments, each pixel region 33 of the pixel definition layer 30 may be a first pixel region 33A.

[0099] Referring to Figure 4, the first pixel 34A has a first maximum emission angle M1 and a second maximum emission angle M2. The first maximum emission angle M1 is the maximum angle between the light emitted from the first pixel 34A and emitted from its first side, and the normal of the display module 300. The second maximum emission angle M2 is the maximum angle between the light emitted from the first pixel 34A and emitted from its second side, and the normal. The first maximum emission angle M1 is smaller than the second maximum emission angle M2, and the first side and the second side do not coincide.

[0100] The first side and the second side are divided using the center line of the first pixel 34A (as shown by P1 in Figure 4) as a reference line. For example, as shown in Figure 4, the first side and the second side can be opposite sides, that is, the angle between the first side and the second side is 180°. Alternatively, in some embodiments, the angle between the first side and the second side can also be an acute angle or an obtuse angle. In addition, the orthographic projection of the light emitted by the first pixel 34A through the light-shielding layer 60 onto the reference plane can be located outside the orthographic projection of the first pixel 34A onto the reference plane, or the orthographic projection of the light emitted by the first pixel 34A through the light-shielding layer 60 onto the reference plane can also be located inside the orthographic projection of the first pixel 34A onto the reference plane.

[0101] Referring again to Figure 4, the first maximum emission angle M1 can also be understood as the angle between the light emitted by the first pixel 34A along the first direction A and the normal of the display module 300, and the second maximum emission angle M2 can also be understood as the angle between the light emitted by the second pixel 34B along the second direction B and the normal of the display module 300. The first direction A and the second direction B intersect but do not coincide, and the plane containing the first direction A and the second direction B is perpendicular to the plane containing the length direction X and the width direction Y of the display module 300.

[0102] Because the first maximum emission angle M1 is smaller than the second emission angle, the user's viewing angle along the first direction A (i.e., the first side) is smaller than the user's viewing angle along the second direction B (i.e., the second side). In other words, the range between the user's viewing line of sight in the first direction A and the normal of the display module 300 is smaller than the range between the user's viewing line of sight in the second direction B and the normal of the display module 300. As a result, the amount of light received by the user when viewing the display module 300 along the first direction A is less than the amount of light received by the user when viewing the display module 300 along the second direction B.

[0103] Therefore, by controlling the size of the first maximum emission angle M1 and the second maximum emission angle M2 of the first pixel 34A according to its specific position in the display module 300, the emission angle of the first pixel 34A is matched with the user's viewing angle, increasing the amount of light received by the user and ensuring that people around cannot see the displayed content, thereby improving the display effect of the display module and enhancing the user's viewing experience.

[0104] In this embodiment, the maximum angle between the light rays emitted from the second pixel 34B and emitted from either side of the second pixel 34B and the normal is the same. For example, as shown in Figure 4, the maximum angle between the light rays emitted from the second pixel 34B and emitted from opposite sides of the second pixel 34B and the normal (as shown in Figure 4, M3 and M4) is the same.

[0105] In this design, either side of the second pixel 34B is divided using the center line of the second pixel 34B (as shown by P2 in Figure 4) as a reference line. Furthermore, the orthographic projection of the light emitted from the second pixel 34B through the light-shielding layer 60 onto the reference plane can be located outside the orthographic projection of the second pixel 34B onto the reference plane, or it can be located inside the orthographic projection of the second pixel 34B onto the reference plane.

[0106] It can be understood that the maximum angle between the light rays emitted from the second pixel 34B and the normal is the same regardless of which side of the second pixel 34B is emitted from it. This can also be understood as the second pixel 34B having equal third maximum emission angle M3 and fourth maximum emission angle M4. Referring to Figure 4, the third maximum emission angle M3 is the angle between the light ray emitted from the second pixel 34B along the third direction C and the normal of the display module 300. The fourth maximum emission angle M4 is the angle between the light ray emitted from the second pixel 34B along the fourth direction D and the normal of the display module 300. The third direction C intersects but does not coincide with the fourth direction D. The plane containing the third direction C and the fourth direction D is perpendicular to the plane containing the length direction X and the width direction Y of the display module 300.

[0107] Since the third maximum emission angle M3 is equal to the fourth maximum emission angle M4, the user's viewing angle along the third direction C is equal to the user's viewing angle along the fourth direction D. In other words, the range between the user's viewing line of sight in the third direction C and the normal of the display module 300 is equal to the range between the user's viewing line of sight in the fourth direction D and the normal of the display module 300. This results in the light received by the user when viewing the display module 300 along the third direction C being equal to the light received by the user when viewing the display module 300 along the fourth direction D.

[0108] Figure 7 is a schematic diagram of the display area of ​​the first display module according to an embodiment of the present application; Figure 8 is a schematic diagram of the display area of ​​the second display module according to an embodiment of the present application; Figure 9 is a schematic diagram of the display area of ​​the third display module according to an embodiment of the present application; Figure 10 is a schematic diagram of the display area of ​​the fourth display module according to an embodiment of the present application; and Figure 11 is a schematic diagram of the display area of ​​the fifth display module according to an embodiment of the present application.

[0109] In this embodiment, the display module 300 has multiple display areas 310, for example, the number of display areas 310 can be five. Of course, the number of display areas 310 can be more or less than five, for example, the number of display areas 310 can be three (as shown in Figure 8) or four (as shown in Figure 9 or 10), or the number of display areas 310 can be seven (as shown in Figure 11). The arrangement of the multiple display areas 310 can include, but is not limited to, the arrangements shown in Figures 7 to 11.

[0110] Each display area 310 is provided with at least one pixel unit 31. Therefore, each display area 310 internally includes a pixel area 33 and a shared area 32. At least one display area 310 is provided with a first pixel area 33A, which can increase the brightness of the display area 310 containing the first pixel area 33A, thus making the display effect of each display area 310 seen by the user more consistent and improving the user's viewing experience.

[0111] For example, referring to Figure 7, the multiple display areas 310 may include a first area 311 and a second area 312. The distance between the first area 311 and the edge of the display module 300 is less than the distance between the second area 312 and the edge of the display module 300. The first area 311 contains at least one first pixel area 33A. The angle between the light emitted from the side of the first pixel area 33A away from the second area 312 and the normal is less than or equal to a first maximum emission angle. The angle between the light emitted from the side of the first pixel area 33A near the second area 312 and the normal is less than or equal to a second maximum emission angle. This results in the first pixel 34A in the first area 311 having a first maximum emission angle M1 on the side away from the central area and a second maximum emission angle M2 on the side facing the central area. The second area 312 contains at least one second pixel area 33B. The angle between the light emitted from either side of the second pixel area 33B near the first area 311 and the normal (e.g., M3 and M4 in Figure 4) is the same.

[0112] The number of first regions 311 can be one or more. When there are multiple first regions 311, the multiple first regions 311 are arranged around the second region 312, as shown in Figure 7, the multiple first regions 311 form a ring-shaped region surrounding the second region 312.

[0113] Since the first region 311 is the edge region of the display module 300 and the second region 312 is the center region of the display module, the second pixel 34B, which has a third maximum emission angle M3 and a fourth maximum emission angle M4, is placed in the center region, while the first pixel 34A, which has a first maximum emission angle M1 and a second maximum emission angle M2, is placed in the edge region. In this way, the first region 311 can emit more light towards the user's eyes, increasing the brightness of the first region 311 and improving the user's viewing experience, thereby enhancing the user's viewing experience of the display screen. Furthermore, it reduces the design complexity of the emission angle of the pixels 34 in the second region 312, which is beneficial for improving the economic efficiency of the display module 300.

[0114] For example, the first pixel 34A in the edge region has a first maximum emission angle M1 on the side away from the center region, and a second maximum emission angle M2 on the side facing the center region. Since the user's viewing angle when viewing the display module 300 is usually located in the center region of the display module 300, by making the first pixel 34A in the edge region face the center region with a larger viewing angle range, the emission angle of the first pixel 34A in the edge region can be adapted to the user's viewing angle, so that the display effect of the edge region seen by the user is almost the same as the display effect of the center region, thereby improving the user's viewing experience.

[0115] In some possible implementations, the first maximum emission angle M1 and the second maximum emission angle M2 of the two first pixels 34A can be different, and the two first pixels 34A belong to two different display areas 310. In this way, by adjusting the first maximum emission angle M1 and the second maximum emission angle M2 of the first pixels 34A within the display area 310 according to their position, the emission angles of the first pixels 34A in different display areas 310 match the user's viewing angle and are opposite to the viewing angles of people around them, further improving the display effect while ensuring privacy protection.

[0116] In some possible implementations, the first maximum emission angle M1 and the second maximum emission angle M2 of any two first pixels 34A in at least one display area 310 are different, and any two first pixels 34A belong to two first pixel areas 33A of the same display area 310. For example, as shown in Figure 7, the first pixels 34A are provided in four of the five display areas 310, and the first maximum emission angle M1 and the second maximum emission angle M2 of any two first pixels 34A in each of the four display areas 310 are different.

[0117] In some other possible implementations, the first maximum emission angle M1 and the second maximum emission angle M2 of any two first pixels 34A in at least one display area 310 are the same, and any two first pixels 34A belong to two first pixel areas 33A of the same display area 310. For example, as shown in Figure 7, two of the five display areas 310 have first pixels 34A. In this case, the first maximum emission angle M1 and the second maximum emission angle M2 of any two first pixels 34A in each of the two display areas 310 are the same.

[0118] In summary, the first maximum emission angle M1 and the second maximum emission angle M2 of any two first pixels 34A in the same display area 310 can be the same or different. This allows the emission angle of the first pixels 34A in different display areas 310 to match the user's viewing angle, improving the display effect while ensuring privacy protection. However, when the first maximum emission angle M1 and the second maximum emission angle M2 of any two first pixels 34A in the same display area 310 are different, the adaptability of the emission angle of each first pixel 34A in the display area 310 to the user's viewing angle can be further increased, further improving the display effect. Furthermore, when the first maximum emission angle M1 and the second maximum emission angle M2 of any two first pixels 34A in the same display area 310 are the same, the design difficulty of the emission angle of each first pixel 34A in the display area 310 can be reduced.

[0119] Figure 12 is a top view of a light-shielding part cooperating with a pixel unit according to an embodiment of this application. Figure 13 is a cross-sectional view of a single pixel unit in the central region of a display module provided in an embodiment of this application. Figure 14 is a cross-sectional view of a single pixel unit in the left edge region of a display module provided in an embodiment of this application. Figure 15 is a first cross-sectional view of a single pixel unit in the right edge region of a display module provided in an embodiment of this application.

[0120] In order to allow light emitted by pixels 34 of pixel area 33 to pass through the light-shielding layer 60, as shown in Figure 4, the light-shielding layer 60 has a plurality of light-transmitting openings 62 arranged in an array. The plurality of light-transmitting openings 62 are arranged one-to-one with the plurality of pixel areas 33. A portion of the light emitted by the corresponding pixel 34 of pixel area 33 passes through the light-transmitting opening 62 (as shown in Figure 13). In other words, the light emitted by the pixel 34 of pixel area 33 passes through its corresponding light-transmitting opening 62 and exits the light-shielding layer 60.

[0121] Since the multiple pixel areas 33 include a first pixel area 33A and a second pixel area 33B, a portion of the light-transmitting openings 62 are used to transmit light emitted from the first pixel 34A, and another portion of the light-transmitting openings 62 are used to transmit light emitted from the second pixel 34B. In some embodiments, when each pixel area 33 is a first pixel area 33A, each light-transmitting opening 62 is used to transmit light emitted from the first pixel 34A.

[0122] A portion of the light emitted from the pixels 34 of the pixel area 33 through the light-transmitting opening 62 enters the user's eyes, thus achieving the display function. Furthermore, by controlling the position of the edge of the light-transmitting opening 62 and the corresponding pixel 34 of the pixel area 33 in a direction perpendicular to the thickness direction Z of the display module 300, the pixel 34 can be designated as either a first pixel 34A or a second pixel 34B.

[0123] For example, referring to FIG14, the distance between the edge of the light-transmitting opening 62 on the first side of the first pixel 34A and the first pixel 34A is a first distance, and the distance between the edge of the light-transmitting opening 62 on the second side of the first pixel 34A and the first pixel 34A is a second distance. The first distance is less than the second distance, so that the first pixel 34A has a first maximum emission angle M1 and a second maximum emission angle M2.

[0124] For example, as shown in FIG13, the distance between the edge of the light-transmitting opening 62 on either side of the second pixel 34B and the second pixel 34B is the same, such that the maximum angle between the light rays emitted from the second pixel 34B and emitted from either side of the second pixel 34B and the normal is the same.

[0125] Therefore, by controlling the distance between the edge of the light-transmitting opening 62 and the edge of the corresponding pixel 34, the center line of the light-transmitting opening 62 is offset relative to the center line of the corresponding pixel 34, making the pixel 34 either the first pixel 34A or the second pixel 34B. In other words, along the circumference of the light-transmitting opening 62, the distance between the inner edge of the light-transmitting opening 62 and the edge of the corresponding pixel 34 in the direction perpendicular to the thickness direction Z of the display module 300 is not equidistant.

[0126] Specifically, when the center line of the light-transmitting opening 62 does not shift relative to the center line of the corresponding pixel 34, the center line of the light-transmitting opening 62 and the center line of the corresponding pixel 34 can coincide (as shown in Figure 13).

[0127] The offset direction of the light-transmitting opening 62 at different positions relative to the corresponding pixel 34 can be towards the center line of the display module 300, for example, along a direction perpendicular to the thickness direction Z of the display module 300 (X direction in Figure 14). The light-transmitting opening 62 located to the left of the center line of the display module 300 is offset to the right relative to the corresponding pixel 34 (as shown in Figure 14), such that the distance between the left edge of the light-transmitting opening 62 and the corresponding pixel 34 is a first distance, and the distance between the right edge of the light-transmitting opening 62 and the corresponding pixel 34 is a second distance. The light-transmitting opening 62 located to the right of the center line of the display module 300 is offset to the left relative to the corresponding pixel 34 (as shown in Figure 15), such that the distance between the right edge of the light-transmitting opening 62 and the corresponding pixel 34 is a first distance, and the distance between the left edge of the light-transmitting opening 62 and the corresponding pixel 34 is a second distance.

[0128] In some embodiments, the orthographic projection of the light-transmitting opening 62 onto the reference plane can be circular, rectangular, or other shapes. In other embodiments, the orthographic projection of the light-transmitting opening 62 onto the reference plane may also include two openings spaced apart along a direction perpendicular to the thickness direction of the display module 300, and the shapes of the openings can be circular, rectangular, or other shapes. The reference plane is the plane containing the length and width directions of the display module.

[0129] Referring to Figure 4, the light-shielding layer 60 includes a first light-shielding layer 611 and a second light-shielding layer 612. The first light-shielding layer 611 and the second light-shielding layer 612 are arranged along the thickness direction Z of the display module 300. The first light-shielding layer 611 is located between the second light-shielding layer 612 and the pixel definition layer 30. The orthographic projections of the first light-shielding layer 611 and the second light-shielding layer 612 on a reference plane overlap. The reference plane is the plane containing the length direction X and the width direction Y of the display module 300. The first light-shielding layer 611 has a first light-transmitting space 613 through which light emitted from the pixel 34 passes, and the second light-shielding layer 612 has a second light-transmitting space 614 through which light emitted from the pixel 34 passes. The second light-transmitting space 614 forms a light-transmitting opening 62 at the end of the display module 300 facing away from the pixel definition layer 30 along the thickness direction Z.

[0130] The first light-shielding layer 611 can block light within a first angle range, and the second light-shielding layer 612 can block light within a second angle range. The first light-shielding layer 611 and the second light-shielding layer 612 can be combined to block light, thereby preventing light leakage. This also blocks light emitted by the pixel 34 within the viewing angle of people around the user, preventing them from seeing the light emitted by the pixel 34 received by the display module 300, thus achieving privacy protection. It should be noted that the first light-shielding layer 611 and the second light-shielding layer 612 are set separately, that is, the first light-shielding layer 611 and the second light-shielding layer 612 are spaced apart along the thickness direction Z of the display module 300. This reduces the molding difficulty and avoids the molding difficulties caused by excessively thick light-shielding layers 60.

[0131] For example, the first light-shielding layer 611 can be a first mesh structure, forming a plurality of first light-transmitting spaces 613, each of which is a through-hole penetrating the first light-shielding layer 611. Since the pixel definition layer 30 is composed of a plurality of pixel units 31, each first light-transmitting space 613 corresponds to a shared area 32 or a pixel area 33, and each first light-transmitting space 613 transmits light emitted from the pixel 34 of the corresponding shared area 32 or the pixel 34 of the corresponding pixel area 33. However, in some embodiments, when the pixel definition layer 30 is composed of a plurality of pixel areas 33, each first light-transmitting space 613 corresponds to one pixel area 33. Each first light-transmitting space 613 transmits light emitted from the pixel 34 of the corresponding pixel area 33.

[0132] It should be noted that the first light-shielding layer 611 can be any other structure besides being an integral first mesh structure. For example, the first light-shielding layer 611 can also be composed of multiple arrayed light-shielding bodies, each of which has a first light-transmitting space 613. In this case, the first light-transmitting space 613 can be a through hole or have a notch in the direction perpendicular to the normal.

[0133] In some embodiments, the orthographic projection of the first light-shielding layer 611 onto the reference plane may overlap with the projection of the pixel 34 of the pixel area 33 onto the reference plane. In other embodiments, the orthographic projection of the first light-shielding layer 611 onto the reference plane may not overlap with the projection of the pixel 34 of the pixel area 33 onto the reference plane.

[0134] In some embodiments, as shown in FIG5, the second light-shielding layer 612 may include a plurality of light-shielding parts 61 arranged in an array. Each light-shielding part 61 has a second light-transmitting space 614 and corresponds to a pixel area 33. Each light-shielding part 61 is used to block a portion of the light emitted by the pixel 34 of the corresponding pixel area 33, so that the light emitted by the pixel 34 of each pixel area 33 within the viewing angle of the surrounding people is blocked, thereby achieving the privacy function. In addition, the light-shielding part 61 can block light from different angle ranges according to the position of the corresponding pixel area 33, so that at least some pixel areas 33 are first pixel areas 33A, improving the display effect of the display module 300, making the display effect of each area seen by the user almost the same, and improving the user's viewing experience.

[0135] The light-shielding part 61 can be made of thermosetting opaque material, optical adhesive doped with black particles, or other materials, so that the light transmittance of the light-shielding part 61 is less than 10%, or even zero.

[0136] Referring to Figure 5, since the pixel unit 31 includes a pixel area 33 and a shared area 32, the light emitted by the pixel 34 in the shared area 32 can be emitted from the gap between adjacent light-shielding parts 61 and pass through the second light-shielding layer 612, and can be received by the user and people around the user, thus realizing shared display.

[0137] In some embodiments, the orthographic projection of the light-shielding part 61 onto the reference plane can be an annular shape, where the reference plane is the plane containing the length direction X and the width direction Y of the display module 300. The orthographic projection of the light-shielding part 61 onto the reference plane can be circular (as shown in Figure 5), rectangular (as shown in Figure 19), racetrack-shaped, or similar shapes.

[0138] In other embodiments, the orthographic projection of the light-shielding part 61 onto the reference plane can be a ring with a notch (as shown in Figure 23). That is, the orthographic projection of the light-shielding part 61 onto the reference plane is an unclosed ring, and the reference plane is the plane containing the length direction X and the width direction Y of the display module 300. The orthographic projection of the light-shielding part 61 onto the reference plane can be a semi-circular ring, a U-shaped shape, an arc shape, or other similar shapes.

[0139] In some other embodiments, the positive projection of the light shielding portion 61 on the reference plane may include a first light shielding segment and a second light shielding segment. The first light shielding segment is an unclosed ring, and the second light shielding segment is located inside the first light shielding segment and connected to the first light shielding segment. The reference plane is the plane where the length direction X and the width direction Y of the display module 300 are located. When the dimension of the pixel 34 in the direction perpendicular to the thickness direction Z of the display module 300 is large, the light shielding portion 61 adopts an E-shaped design (as shown in FIG. 24), which can further increase the angular range of the light emitted by the pixel 34 blocked by the light shielding portion 61, prevent the light emitted by the pixel 34 within the viewing angle of the people around the user from not being blocked, and improve the anti-peeping effect.

[0140] Exemplarily, the first light shielding segment may include a first straight segment, a second straight segment, and a third straight segment connected in sequence. The first straight segment is perpendicular to the second straight segment, and the second straight segment is perpendicular to the third straight segment. The first straight segment, the second straight segment, and the third straight segment form a U-shaped structure. The second light shielding segment is a bar-shaped structure, and the second light shielding segment is located between the first straight segment and the third straight segment and connected to the second straight segment.

[0141] In still some other embodiments, the positive projection of the light shielding portion 61 on the reference plane may include a first light shielding segment and a second light shielding segment. The first light shielding segment is a ring, and the second light shielding segment is located inside the first light shielding segment and connected to the first light shielding segment. In this way, the light shielding portion 61 is similar to a Chinese character 'ri' (日). When the dimension of the pixel 34 in the direction perpendicular to the thickness direction Z of the display module 300 is large, it can also further increase the angular range of the light emitted by the pixel 34 blocked by the light shielding portion 61, prevent the light emitted by the pixel 34 within the viewing angle of the people around the user from not being blocked, and improve the anti-peeping effect.

[0142] In some other embodiments, the second light shielding layer 612 may also be a second mesh structure, and the second mesh structure forms a plurality of second light-transmitting spaces 614 and a plurality of third light-transmitting spaces (not shown in the figure). Each second light-transmitting space 614 and the third light-transmitting space are through holes penetrating the second light shielding layer 612. Since the pixel definition layer 30 is composed of a plurality of pixel units 31, at this time, each second light-transmitting space 614 corresponds to a pixel region 33 and transmits the light emitted by the pixel 34 in the corresponding pixel region 33, and each third light-transmitting space corresponds to a shared region 32 and transmits the light emitted by the pixel 34 in the corresponding shared region 32. However, in some embodiments, when the pixel definition layer 30 is composed of a plurality of pixel regions 33, the second mesh structure forms a plurality of second light-transmitting spaces 614, and each second light-transmitting space 614 corresponds to a pixel region 33 and transmits the light emitted by the pixel 34 in the corresponding pixel region 33.

[0143] In some embodiments, the orthographic projection of the second light-shielding layer 612 onto the reference plane may overlap with the projection of the pixel 34 of the pixel region 33 onto the reference plane. In other embodiments, the orthographic projection of the second light-shielding layer 612 onto the reference plane may not overlap with the projection of the pixel 34 of the pixel region 33 onto the reference plane.

[0144] Figure 16 is a second cross-sectional view of a single pixel unit located in the right edge region of the display module provided in the embodiment of this application. Figure 17 is a third cross-sectional view of a single pixel unit located in the right edge region of the display module provided in the embodiment of this application. Figure 18 is a fourth cross-sectional view of a single pixel unit located in the right edge region of the display module provided in the embodiment of this application.

[0145] The connection relationship between the first light-shielding layer 611 and the second light-shielding layer 612 is described below.

[0146] In some possible implementations, at least a portion of the first light-shielding layer 611 and at least a portion of the second light-shielding layer 612 are spaced apart in the thickness direction Z of the display module 300.

[0147] For example, referring to Figure 15, the first light-shielding layer 611 and the second light-shielding layer 612 can be arranged at intervals along the thickness direction Z of the display module 300. That is, along the direction perpendicular to the thickness direction Z of the display module 300, the projections of the first light-shielding layer 611 and the second light-shielding layer 612 of each light-shielding part 61 do not overlap. When the first light-shielding layer 611 and the second light-shielding layer 612 are arranged at intervals, the manufacturing difficulty of the light-shielding part 61 can be reduced, which is beneficial to improving the economy of the display module 300.

[0148] In some embodiments, referring to FIG16, a portion of the first light-shielding layer 611 is connected to a portion of the second light-shielding layer 612, and another portion of the first light-shielding layer 611 and another portion of the second light-shielding layer 612 are spaced apart along the thickness direction Z of the display module 300. In this case, a portion of the orthographic projection of the first light-shielding layer 611 on the reference plane is located inside the orthographic projection of the second light-shielding layer 612 on the reference plane.

[0149] Specifically, the second light-shielding layer 612 includes a plurality of light-shielding portions 61. Each light-shielding portion 61 may include a first portion and a second portion. The first portion has a second light-transmitting space 614. The first portion and the first light-shielding layer 611 are spaced apart along the thickness direction Z of the display module 300. The second portion is located between the first portion and the first light-shielding layer 611. The opposite ends of the second portion are respectively connected to the first portion and the first light-shielding layer 611. The orthographic projection of the second portion on the reference plane overlaps with the orthographic projection of the first portion on the reference plane.

[0150] In some other possible implementations, at least a portion of the first light-shielding layer 611 and at least a portion of the second light-shielding layer 612 are connected in the thickness direction Z of the display module 300.

[0151] For example, referring to Figure 17, the height of the first light-shielding layer 611 in the thickness direction Z of the display module 300 is equal to the distance between the second light-shielding layer 612 and the touch layer 50 in the thickness direction Z of the display module 300. At this time, a part of the first light-shielding layer 611 is connected to a part of the light-shielding portion 61, and a part of the orthographic projection of the light-shielding portion 61 on the reference plane is located inside the orthographic projection of the first light-shielding layer 611 on the reference plane.

[0152] In some other embodiments, as shown in FIG18, the first light-shielding layer 611 and the second light-shielding layer 612 are connected, that is, the first light-shielding layer 611 and the second light-shielding layer 612 can be an integral structure.

[0153] In some possible implementations, the second light-transmitting space 614 may include at least one through-hole penetrating the second light-shielding layer 612. For example, the second light-transmitting space 614 may include one through-hole penetrating the second light-shielding layer 612 (as shown in Figure 13). Of course, the second light-transmitting space 614 may also include two through-holes penetrating the second light-shielding layer 612. In this case, the orthographic projection of the second light-transmitting space 614 on the reference plane may be an annular or a rectangular shape.

[0154] In some other possible implementations, the second light-transmitting space 614 may also have a gap in the direction perpendicular to the normal. That is, the orthographic projection of the second light-transmitting space 614 onto the reference plane is an unclosed ring. In this case, the shape of the orthographic projection of the second light-transmitting space 614 onto the reference plane can be a U-shape, an E-shape, or other shapes.

[0155] The notch in the second light-transmitting space 614 is usually located on the bottom side (or ground side) of the display module 300, which reduces the design difficulty of the second light-shielding layer 612 while improving the display effect of the display module 300.

[0156] Figure 19 is a top view of the third type of pixel definition layer and second light-shielding layer cooperation provided in the embodiments of this application; Figure 20 is a top view of the fourth type of pixel definition layer and second light-shielding layer cooperation provided in the embodiments of this application; Figure 21 is a top view of the fifth type of pixel definition layer and second light-shielding layer cooperation provided in the embodiments of this application; Figure 22 is a top view of the sixth type of pixel definition layer and second light-shielding layer cooperation provided in the embodiments of this application; Figure 23 is a top view of the seventh type of pixel definition layer and second light-shielding layer cooperation provided in the embodiments of this application; Figure 24 is a top view of the eighth type of pixel definition layer and second light-shielding layer cooperation provided in the embodiments of this application; Figure 25 is a top view of the ninth type of pixel definition layer and second light-shielding layer cooperation provided in the embodiments of this application; and Figure 26 is a top view of the tenth type of pixel definition layer and second light-shielding layer cooperation provided in the embodiments of this application.

[0157] The shapes of the shared area 32 and the pixel area 33, as well as their positional relationship, are described below.

[0158] In this embodiment, the shape of the pixel area 33 can be circular (as shown in Figure 5 or Figure 6), rectangular (as shown in Figure 23 or Figure 24), elliptical (as shown in Figure 26), etc.

[0159] In this embodiment of the application, the shape of the shared area 32 can be circular (as shown in Figure 5 or Figure 6), rectangular (as shown in Figure 23 or Figure 24), elliptical (as shown in Figure 26), circular ring (as shown in Figure 5 or Figure 6), rectangular ring (as shown in Figure 19 or Figure 20), etc.

[0160] In some embodiments, the pixel region 33 and the shared region 32 may have the same shape. In some embodiments, as shown in FIG25, both the pixel region 33 and the shared region 32 may be circular. In other embodiments, as shown in FIG26, both the pixel region 33 and the shared region 32 may be elliptical. In still other embodiments, as shown in FIG23, both the pixel region 33 and the shared region 32 may be rectangular.

[0161] In some embodiments, the shapes of pixel region 33 and shared region 32 may also be different. In some embodiments, as shown in FIG5, the shape of pixel region 33 may be circular, and in this case, the shape of shared region 32 may be annular. In other embodiments, as shown in FIG20, the shape of pixel region 33 may be rectangular, and in this case, the shape of shared region 32 may be a rectangular ring.

[0162] In some implementations, in each pixel unit 31, at least a portion of the orthographic projection of the pixel region 33 onto the reference plane may be located inside the orthographic projection of the shared region 32 onto the reference plane, that is, the shared region 32 is arranged around at least a portion of the pixel region 33.

[0163] For example, referring to Figure 5, the orthographic projection of the shared area 32 onto the reference plane can be an annular shape, and the orthographic projection of the pixel area 33 onto the reference plane can be a circle. The orthographic projection of the pixel area 33 is located inside the orthographic projection of the shared area 32. Alternatively, referring to Figure 19, the orthographic projection of the shared area 32 onto the reference plane can be a rectangular ring, and the orthographic projection of the pixel area 33 onto the reference plane can be a rectangle. The orthographic projection of the pixel area 33 is located inside the orthographic projection of the shared area 32. Therefore, it can be seen that the orthographic projection of the pixel area 33 onto the reference plane is located inside the orthographic projection of the shared area 32 onto the reference plane.

[0164] However, a portion of the orthographic projection of pixel region 33 onto the reference plane may be located inside the orthographic projection of shared region 32 onto the reference plane, and another portion may be located outside the orthographic projection of shared region 32 onto the reference plane. For example, the orthographic projection of shared region 32 onto the reference plane may be a semi-circular ring, and the orthographic projection of pixel region 33 onto the reference plane may be a circle, with a portion of the orthographic projection of pixel region 33 located inside the semi-circular ring.

[0165] In some other embodiments, as shown in FIG21, in each pixel unit 31, the shared area 32 and the pixel area 33 may be arranged in a direction perpendicular to the thickness direction Z of the display module 300, that is, the shared area 32 is located outside the pixel area 33 and is arranged side by side with the pixel area 33.

[0166] In some embodiments, referring to FIG21, in each pixel unit 31, a shared region 32 and a pixel region 33 may be connected. The shared region 32 and the pixel region 33 may be arranged along a direction perpendicular to the thickness direction Z of the display module 300 (as shown in FIG22 or FIG23), or at least a portion of the orthographic projection of the pixel region 33 onto the reference plane may be located inside the orthographic projection of the shared region 32 onto the reference plane (as shown in FIG19 or FIG20).

[0167] In other embodiments, in each pixel unit 31, the shared area 32 and the pixel area 33 are spaced apart along a direction perpendicular to the thickness direction Z of the display module 300, that is, the shared area 32 and the pixel area 33 are arranged side by side. The shared area 32 and the pixel area 33 may be arranged along a direction perpendicular to the thickness direction Z of the display module 300 (as shown in Figure 26).

[0168] In some possible implementations, as shown in Figure 22, the pixel definition layer 30 may include multiple pixel columns arranged side-by-side along a fifth direction (X direction in Figure 22). Each pixel column includes multiple pixel units 31 arranged along a sixth direction (Y direction in Figure 22). The shared area 32 and pixel area 33 in each pixel unit 31 are arranged side-by-side. The relative positions of the pixel area 33 and the shared area 32 in two adjacent pixel columns are opposite, which can be used to supplement the vertical viewing angle and improve the user's viewing experience.

[0169] The relative position of pixel area 33 and shared area 32 can be understood as the relative position of pixel area 33 and shared area 32 in the sixth direction within the same pixel unit 31.

[0170] For example, referring to Figure 22, the pixel definition layer 30 may include four pixel columns arranged along the fifth direction. Each pixel column may include three pixel units 31. The shared region 32 in each pixel unit 31 is arranged side by side with the pixel unit 33, and the shared region 32 in each pixel unit 31 is connected to the pixel unit 33. Along the fifth direction from left to right, the shared region 32 in the first pixel column is located below the corresponding pixel unit 33 along the sixth direction, the shared region 32 in the second pixel column is located above the corresponding pixel unit 33 along the sixth direction, the shared region 32 in the third pixel column is located below the corresponding pixel unit 33 along the sixth direction, and the shared region 32 in the fourth pixel column is located above the corresponding pixel unit 33 along the sixth direction.

[0171] The relative positions of the pixel area 33 and the shared area 32 in the same pixel unit 31 are determined by the sixth direction from top to bottom.

[0172] It should be noted that, in addition to being reversed, the relative positions of pixel areas 33 and shared areas 32 in two adjacent pixel columns can also be the same in some embodiments. For example, as shown in Figure 21, the shared areas 32 in each pixel column are located above pixel areas 33. Of course, the shared areas 32 in each pixel column can also all be located above pixel areas 33.

[0173] Figure 27 is a schematic diagram of a pixel driving circuit board provided in an embodiment of this application.

[0174] In some possible implementations, all pixels 34 in each pixel unit 31 are electrically connected to the same pixel 34 driving circuit. That is, the pixels 34 in pixel area 33 and the pixels 34 in shared area 32 are electrically connected to the same pixel 34 driving circuit. When the pixels 34 in pixel area 33 and shared area 32 are lit simultaneously, the current of the pixels 34 in pixel area 33 can be reduced. This not only ensures that the brightness of the display module 300 remains unchanged before and after the pixels 34 in shared area 32 are lit, but also extends the lifespan of the pixels 34 in pixel area 33.

[0175] The structure of the pixel 34 driving circuit is not specifically limited here. For example, as shown in Figure 27, all pixels 34 in each pixel unit 31 can be electrically connected to the same 8T1C circuit. The 8T1C is a standard LTPO pixel circuit, including three processes: reset, data writing & compensation, and light emission. A T9 switch is used as a toggle switch between shared mode and privacy mode.

[0176] When EMs is the off voltage, T9 is in the off state, so only the privacy mode is enabled and the sharing mode is disabled.

[0177] When the EMS input is turned on, transistor T9 is in the on state, and both the privacy mode and the sharing mode are activated simultaneously. At this time, the current is diverted; while pixel 34 in the sharing area 32 is lit, the current to pixel 34 in pixel area 33 decreases, maintaining the same brightness of the display screen 200 before and after the function is activated. This extends the lifespan of pixel 34 in pixel area 33.

[0178] In some possible implementations, continuing to refer to Figure 4, the display module 300 may further include a brightness enhancement layer 70, with a first light-shielding layer 611 and the brightness enhancement layer 70 arranged in the same layer, and a second light-shielding layer 612 arranged on the light-emitting side of the first light-shielding layer 611 and on the light-emitting side of the brightness enhancement layer 70. The brightness enhancement layer 70 concentrates the light emitted from the first light-shielding layer 611 through the second light-shielding layer 612, increasing the amount of light passing through the second light-shielding layer 612, which helps to improve the brightness of the privacy mode.

[0179] Referring to Figure 4, the brightness enhancement layer 70 includes a plurality of brightness enhancement elements 71 arranged in an array. The plurality of brightness enhancement elements 71 are arranged one-to-one with a plurality of pixel areas 33. At least a portion of the light emitted by the pixel 34 of each pixel area 33 passes through its corresponding brightness enhancement element 71. For example, a portion of the light emitted by the pixel 34 of each pixel area 33 passes through its corresponding brightness enhancement element 71, increasing the amount of light passing through the light-transmitting opening 62, which helps to further improve the display effect.

[0180] As shown in Figure 4, the brightening layer 70 can be located inside the planarization layer 90. The refractive index of the brightening body 71 is greater than that of the planarization layer 90, ensuring that the brightening body 71 can achieve the effect of light focusing and brightening.

[0181] For example, as shown in Figure 4, the brightness enhancer 71 is a lens structure. The orthographic projection of the brightness enhancer 71 on the reference plane can be a circle. The cross-sectional shape of the brightness enhancer 71 perpendicular to the reference plane can be formed by an arc and a straight line. That is to say, the cross-sectional shape of the brightness enhancer 71 perpendicular to the reference plane can be an arc.

[0182] It should be noted that the brightness enhancement body 71 can be other structures besides a lens structure. For example, the brightness enhancement body 71 can be a block structure, the orthographic projection of the brightness enhancement body 71 on the reference plane can be a rectangle, and the cross-sectional shape of the brightness enhancement body 71 perpendicular to the reference plane can be a right trapezoid.

[0183] For example, referring to FIG13, the thickness of the brightness enhancer 71 along the thickness direction Z of the display module 300 is greater than the thickness of the first light-shielding layer 611 along the thickness direction Z of the display module 300. However, the thickness of the brightness enhancer 71 along the thickness direction Z of the display module 300 may also be equal to or less than the thickness of the first light-shielding layer 611 along the thickness direction Z of the display module 300.

[0184] For example, referring to Figure 13, the brightness enhancer 71 passes through the first light-transmitting space 613 and is located outside the second light-transmitting space 614, thus realizing that the brightness enhancer layer 70 and the first light-shielding layer 611 are disposed in the same layer. However, in some embodiments, the brightness enhancer 71 may also pass through the first light-transmitting space 613 and a part of the brightness enhancer 71 may be located inside the second light-transmitting space 614.

[0185] In some possible implementations, the orthographic projection of each brightener 71 onto a reference plane at least partially overlaps with the orthographic projection of each pixel 34 of the corresponding pixel area 33 onto the reference plane, where the reference plane is the plane containing the length direction X and the width direction Y of the display module 300. This ensures that the brightener 71 converges the light emitted by the pixel 34, thereby achieving brightening.

[0186] For example, as shown in FIG13, the orthographic projection of the brightening body 71 on the reference plane overlaps with the orthographic projection of each pixel 34 of the corresponding pixel area 33 on the reference plane. That is, the orthographic projection of each pixel 34 of the corresponding pixel area 33 on the reference plane is disposed inside the orthographic projection of the corresponding pixel area 33 on the reference plane.

[0187] Of course, the orthographic projection of the brightening body 71 on the reference plane can also overlap with the orthographic projection of each pixel 34 of the corresponding pixel area 33 on the reference plane. That is, the orthographic projection of the brightening body 71 on the reference plane contains a portion of the orthographic projection of each pixel 34 of the corresponding pixel area 33 on the reference plane.

[0188] For example, a portion of the brightening body 71 in the brightening layer 70 may have an orthographic projection of each pixel 34 of the corresponding pixel area 33 on the reference plane inside its orthographic projection on the reference plane, and another portion of the brightening body 71 may have a portion of an orthographic projection of each pixel 34 of the corresponding pixel area 33 on the reference plane inside its orthographic projection on the reference plane.

[0189] In some possible implementations, multiple brightness enhancers 71 are arranged in a one-to-one correspondence with multiple light-transmitting openings 62. At least a portion of the orthographic projection of each brightness enhancer 71 onto a reference plane is disposed inside the orthographic projection of the corresponding light-transmitting opening 62 onto the reference plane, which is the plane containing the length direction X and the width direction Y of the display module 300. This ensures that light passing through the brightness enhancer 71 can pass through the light-transmitting opening 62.

[0190] For example, a portion of the orthographic projection of the brightness enhancer 71 onto the reference plane can be disposed inside the orthographic projection of the corresponding light-transmitting opening 62 onto the reference plane. Of course, the orthographic projection of the brightness enhancer 71 onto the reference plane can also be disposed inside the orthographic projection of the corresponding light-transmitting opening 62 onto the reference plane.

[0191] In some embodiments, a portion of the orthographic projection of a portion of the brightening element 71 in the brightening layer 70 onto the reference plane may be disposed inside the orthographic projection of the corresponding light-transmitting opening 62 onto the reference plane, and another portion of the orthographic projection of the brightening element 71 onto the reference plane may also be disposed inside the orthographic projection of the corresponding light-transmitting opening 62 onto the reference plane. In other embodiments, a portion of the orthographic projection of each brightening element 71 in the brightening layer 70 onto the reference plane may be disposed inside the orthographic projection of the corresponding light-transmitting opening 62 onto the reference plane. In still other embodiments, the orthographic projection of each brightening element 71 in the brightening layer 70 onto the reference plane may also be disposed inside the orthographic projection of the corresponding light-transmitting opening 62 onto the reference plane.

[0192] Example 2

[0193] Figure 28 is a top view of the pixel definition layer and the second light-shielding layer in the second display module provided in this application embodiment, and Figure 29 is a cross-sectional view of the second display module provided in this application embodiment. Figure 28 is only used to illustrate the arrangement of the multiple pixel areas 33 and does not constitute a limitation on the arrangement or number of the multiple pixel areas 33. Figure 29 is used to illustrate the emission angle of pixels 34 in different areas of the display module 300 and does not imply that the specific structure of the display module 300 is as shown in Figure 29.

[0194] Referring to Figure 29, the display module 300 may include a substrate 10, a circuit layer 20, a pixel definition layer 30, an encapsulation layer 40, a touch layer 50, a light-shielding layer 60, and a surface base layer 80 stacked together. The display module 300 also includes a planarization layer 90 and a brightness enhancement layer 70, both of which are located inside the planarization layer 90.

[0195] The difference between Figure 29 and Figure 4 lies in the structure of the pixel definition layer 30. Specifically, referring to Figure 28, the pixel definition layer 30 includes multiple pixel regions 33 (or privacy regions) arranged in an array, each pixel region 33 including at least one pixel 34. The multiple pixel regions 33 may include a first color region, a second color region, and a third color region, which are used to emit different colors of light. For example, the first color region emits red light, the second color region emits green light, and the third color region emits blue light. Alternatively, the multiple pixel regions 33 can also be composed of color regions used to emit at least four different colors of light.

[0196] The arrangement of the multiple pixel areas 33 is not limited here. In some embodiments, the multiple pixel areas 33 are arranged in a triangular arrangement. In other embodiments, the multiple pixel areas 33 can also be arranged in a square arrangement. In still other embodiments, the multiple pixel areas 33 can also be arranged in a diamond arrangement.

[0197] The light-blocking layer 60 is used to block at least a portion of the light emitted by the pixels 34 of each pixel area 33, so that the emission angle of the pixels 34 of each pixel area 33 is controlled within a corresponding range. This not only allows a portion of the light emitted by the pixels 34 of each pixel area 33 to enter the user's eyes, thus enabling the display function, but also blocks a portion of the light emitted by the pixels 34 of each pixel area 33 that falls within the viewing angle of people around the user, preventing them from receiving the light emitted by the pixels 34 of the pixel area 33, thereby achieving privacy display.

[0198] Under the blocking effect of the light-shielding layer 60, as shown in Figure 29, the multiple pixel areas 33 may include a first pixel area 33A and a second pixel area 33B. Pixel 34 of the first pixel area 33A is called first pixel 34A, and pixel 34 of the second pixel area 33B is called second pixel 34B. The number of first pixel areas 33A and the number of second pixel areas 33B can be one or more. It should be noted that, in addition to being composed of first pixel areas 33A and second pixel areas 33B, in some embodiments, each pixel area 33 of the pixel definition layer 30 can be a first pixel area 33A.

[0199] Referring to Figure 29, the first pixel 34A has a first maximum emission angle M1 and a second maximum emission angle M2. The first maximum emission angle M1 is the maximum angle between the light emitted from the first pixel 34A and emitted from its first side, and the normal of the display module 300. The second maximum emission angle M2 is the maximum angle between the light emitted from the first pixel 34A and emitted from its second side, and the normal. The first maximum emission angle M1 is smaller than the second maximum emission angle M2, and the first side and the second side do not coincide.

[0200] The first side and the second side are divided using the center line of the first pixel 34A as a reference line (as shown by P1 in Figure 29). For example, the first side and the second side can be opposite sides, that is, the angle between the first side and the second side is 180°. Alternatively, in some embodiments, the angle between the first side and the second side can also be an acute angle or an obtuse angle. In addition, the orthographic projection of the light emitted by the first pixel 34A through the light-shielding layer 60 onto the reference plane can be located outside the orthographic projection of the first pixel 34A onto the reference plane, or the orthographic projection of the light emitted by the first pixel 34A through the light-shielding layer 60 onto the reference plane can also be located inside the orthographic projection of the first pixel 34A onto the reference plane.

[0201] Referring again to Figure 29, the first maximum emission angle M1 can also be understood as the angle between the light emitted by the first pixel 34A along the first direction A and the normal of the display module 300. The second maximum emission angle M2 can also be understood as the angle between the light emitted by the first pixel 34A along the second direction B and the normal of the display module 300. The first direction A and the second direction B intersect but do not coincide. The plane containing the first direction A and the second direction B is perpendicular to the plane containing the length direction X and the width direction Y of the display module 300.

[0202] Because the first maximum emission angle M1 is smaller than the second emission angle, the user's viewing angle along the first direction A is smaller than the user's viewing angle along the second direction B. In other words, the range between the user's viewing line of sight in the first direction A (i.e., the first side) and the normal of the display module 300 is smaller than the range between the user's viewing line of sight in the second direction B (i.e., the second side) and the normal of the display module 300. As a result, the light received by the user when viewing the display module 300 along the first direction A is less than the light received by the user when viewing the display module 300 along the second direction B.

[0203] Therefore, by controlling the size of the first maximum emission angle M1 and the second maximum emission angle M2 of the first pixel 34A according to its specific position in the display module 300, the emission angle of the first pixel 34A is matched with the user's viewing angle, increasing the amount of light received by the user and ensuring that people around cannot see the displayed content, thereby improving the display effect of the display module and enhancing the user's viewing experience.

[0204] In this embodiment, the maximum angle between the light rays emitted from the second pixel 34B and emitted from either side of the second pixel 34B and the normal is the same. For example, as shown in FIG29, the maximum angle between the light rays emitted from the second pixel 34B and emitted from opposite sides of the second pixel 34B and the normal is the same.

[0205] In this design, either side of the second pixel 34B is divided using the center line of the second pixel 34B as a reference line (as shown in P2 of Figure 29). Furthermore, the orthographic projection of the light emitted from the second pixel 34B through the light-shielding layer 60 onto the reference plane can be located outside the orthographic projection of the second pixel 34B onto the reference plane, or it can be located inside the orthographic projection of the second pixel 34B onto the reference plane.

[0206] It can be understood that the maximum angle between the light rays emitted from the second pixel 34B and the normal is the same regardless of which side of the second pixel 34B is emitted from it. This can also be understood as the second pixel 34B having equal third maximum emission angle M3 and fourth maximum emission angle M4. Referring to Figure 29, the third maximum emission angle M3 is the angle between the light ray emitted from the second pixel 34B along the third direction C and the normal of the display module 300. The fourth maximum emission angle M4 is the angle between the light ray emitted from the second pixel 34B along the fourth direction D and the normal of the display module 300. The third direction C intersects but does not coincide with the fourth direction D. The plane containing the third direction C and the fourth direction D is perpendicular to the plane containing the length direction X and the width direction Y of the display module 300.

[0207] Since the third maximum emission angle M3 is equal to the fourth maximum emission angle M4, the user's viewing angle along the third direction C is equal to the user's viewing angle along the fourth direction D. In other words, the range between the user's viewing line of sight in the third direction C and the normal of the display module 300 is equal to the range between the user's viewing line of sight in the fourth direction D and the normal of the display module 300. This results in the light received by the user when viewing the display module 300 along the third direction C being equal to the light received by the user when viewing the display module 300 along the fourth direction D.

[0208] In summary, even after removing the shared area 32, the display module 300 can still adapt to the user's viewing angle, improve the performance of the display screen 200, and enhance the user's viewing experience.

[0209] It should be noted that the shapes of the brightening layer 70, the light-shielding layer 60, and the pixel area 33, as well as the relative relationship between the pixel area 33 and the light-shielding layer 60, have been described in detail in Embodiment 1, and therefore will not be repeated here.
