[0021] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be fully described below in conjunction with the accompanying drawings of the embodiments of the present invention through specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0022] Figure 11 is a schematic structural diagram of a display module provided by an embodiment of the present invention; Figure 2 is a structural diagram of another display module provided by an embodiment of the present invention, Figure 3 yes Figure 1 A schematic diagram of a cross-sectional structure of a display module along the section line AA' is provided. Figure 4 yes Figure 2 A schematic diagram of a cross-sectional structure of the display module provided along the section line BB', combined with Figure 1-Figure 4 As shown, the display module 100 provided by the embodiment of the present invention includes a display panel 10, the display panel 10 includes a display area 11 and a light-transmitting area 12, and along the thickness direction of the display panel (the X direction as shown in the figure), the light-transmitting area 12 penetrates at least part of the film layer in the display panel 10; a light-shielding layer 20 is located on one side of the display panel 10, and the light-shielding layer 20 includes a hollow portion 21 and a first light-shielding section 22 and a second light-shielding section 23 arranged around the hollow portion, and along the thickness direction of the display panel (the X direction as shown in the figure), the hollow portion 21, the first light-shielding section 22 and the second light-shielding section 23 all overlap with the light-transmitting area 12; along the first direction (the Y direction as shown in the figure), the size of the first light-shielding section 22 is larger than the size of the second light-shielding section 23, and the first direction is parallel to the direction from the center of the light-transmitting area to the center of the hollow portion.

[0023] Exemplarily, the display panel 10 includes a display area 11 and a light-transmitting area 12. The display area 11 is provided with a plurality of display sub-pixels (not shown in the figure). The display sub-pixels are used to display images according to display requirements to realize the display function of the display panel. Optionally, the embodiment of the present invention does not limit the specific type of the display panel. For example, the display panel may be an organic light-emitting diode display panel, a micro light-emitting diode display panel, a liquid crystal display panel, or other display panels that can realize the light-transmitting area solution. The display panel 10 includes a structure for realizing the display function, such as an array substrate and a light-emitting element (not shown in the figure). The array substrate may include a pixel circuit, for example, and the pixel circuit is used to drive the light-emitting element to emit light. The pixel circuit may include at least one thin film transistor. The light-emitting element has different settings depending on the type of the display panel. The embodiment of the present invention does not limit the specific structure of the display panel.

[0024] The light-transmitting area 12 may be provided with a sensor, such as an optical sensor or a distance sensor, for realizing other additional functions of the display module, such as imaging or sensing distance. Furthermore, the light-transmitting area 12 may penetrate at least part of the film layer in the display panel 10. Figure 3 and Figure 4 The light-transmitting area 12 completely penetrates the display panel 10 to form a through hole as an example for description.

[0025] The light-shielding layer 20 is disposed on the light-emitting side of the display panel 10, corresponding to the light-transmitting area 12 of the display panel 10. The light-shielding layer 20 includes a hollow portion 21, a first light-shielding sub-portion 22, and a second light-shielding sub-portion 23. The hollow portion 21 exposes the light-transmitting area 12, further exposing sensors, such as optical sensors, disposed therein. This ensures that the sensors disposed therein can properly transmit signals and perform sensing functions. The first light-shielding sub-portion 22 and the second light-shielding sub-portion 23 are disposed around the hollow portion 21 to shield the edge of the light-transmitting area 12. This prevents visible wiring disposed at the edge of the light-transmitting area 12 and prevents reflection of light from the wiring, thereby improving the sensing quality of the optical sensor.

[0026] Furthermore, in the prior art, the light-transmitting area and the hollow portion are concentric structures, that is, the first light-shielding section and the second light-shielding section arranged around the hollow portion are symmetrical structures, and the coverage areas of the first light-shielding section and the second light-shielding section are relatively small, and it is impossible to set other structures in the areas corresponding to the first light-shielding section and / or the second light-shielding section, resulting in the areas corresponding to the first light-shielding section and the second light-shielding section being idle, and the display module having a single function. Different from the solutions in the prior art, the embodiment of the present invention creatively sets the light-transmitting area 12 and the hollow portion 21 as non-concentric structures, that is, the first light-shielding section 22 and the second light-shielding section 23 arranged around the hollow portion 21 are asymmetrical structures, and the size of the first light-shielding section 22 is set to be larger than the size of the second light-shielding section 23, such as Figure 3 and Figure 4 As shown in the figure, along the first direction (the Y direction shown in the figure), the size b of the first shading section 22 is larger than the size a of the second shading section 23. In this way, other structures can be set in the first shading section 22 with a larger size, so as to make full use of the area covered by the first shading section 22 to avoid idle space, and to improve the function of the display module and enhance the functional integration of the display module.

[0027] It should be noted that the embodiment of the present invention does not limit the specific sizes of the first light-shielding section and the second light-shielding section. In actual products, the sizes of the first light-shielding section and the second light-shielding section can be set according to design requirements to meet product requirements.

[0028] It should be noted that the display module provided by the embodiment of the present invention may further include other structures for realizing the normal functions of the display module, which is not limited in the embodiment of the present invention.

[0029] In summary, the display module provided by the embodiment of the present invention, by setting a light-shielding layer, and at the same time setting the light-shielding layer to include a hollow portion and a first light-shielding section and a second light-shielding section surrounding the hollow portion, the optical sensor set in the light-transmitting area is exposed through the hollow portion, thereby ensuring that the optical sensor can receive light normally; by setting the first light-shielding section and the second light-shielding section in the light-transmitting area, the first light-shielding section and the second light-shielding section block the wiring set around the light-transmitting area, the problem of visible wiring can be avoided, and the reflection of light by the wiring can be avoided, thereby improving the sensing quality of the optical sensor; further, by setting the size of the first light-shielding section to be larger than the size of the second light-shielding section, other structures can be set in the first light-shielding section with a larger size, so as to facilitate the improvement of the function of the display module.

[0030] Based on the above embodiments, Figure 5 yes Figure 1 Another cross-sectional structural diagram of the display module provided along the section line AA' is shown as follows: Figure 5 As shown, the light-transmitting area 12 exposes the side wall of the display panel 10; the display module 100 further includes an anti-static structure 30 covering the side wall, and along the thickness direction of the display panel 10 (the X direction shown in the figure), the first light-shielding portion 22 covers the anti-static structure 30.

[0031] For example, the through-hole structure formed in the light-transmitting area 12 will expose the side wall of the display panel 10, which will cause static electricity to enter the display area 11 along the side wall of the display panel 10 to a certain extent, affecting the display effect of the display area 11. The display module 100 is also provided with an anti-static structure 30 covering the side wall. The anti-static structure 30 can block the entry path of surrounding static electricity and prevent static electricity from affecting the normal display of the display panel. Furthermore, along the thickness direction of the display panel 10 (i.e., the X direction shown in the figure), the first light-shielding section 22 covers the anti-static structure 30. It can be understood that the anti-static structure 30 is provided in the area covered by the larger first light-shielding section 22. In this way, the anti-static structure 30 has sufficient space for installation, ensuring that the installation method of the anti-static structure 30 is simple.

[0032] It should be noted that the embodiment of the present invention does not limit the specific structure of the anti-static structure. As long as the structure can prevent static electricity from entering the display panel, it falls within the protection scope of the embodiment of the present invention.

[0033] The display module provided by the embodiment of the present invention can, to a certain extent, block the path of static electricity around the through-hole structure from entering the display area by providing an anti-static structure covering the side wall of the display panel, thereby improving the anti-static ability of the display panel; and by providing a first shading section covering the anti-static structure along the thickness direction of the display panel, by covering the anti-static structure with the larger first shading section, on the one hand, it can be ensured that there is sufficient space to accommodate the anti-static structure, and on the other hand, the area covered by the first shading section can be fully utilized to avoid idle space, thereby further improving the functional integration of the display module.

[0034] Next, the specific configuration of the light-transmitting area 12 and the hollow portion 21 will be described.

[0035] First, the following description will be made by taking the example that the shape of the light-transmitting area 12 is different from the shape of the hollow portion 21 .

[0036] Continue to refer Figure 1 and Figure 3 As shown, the hollow portion 21 includes a hollow boundary 211, which defines the setting area of ​​the hollow portion 21; the light-transmitting area 12 includes a light-transmitting boundary 121, which defines the setting area of ​​the light-transmitting area 12; the shape of the light-transmitting boundary is different from the shape of the hollow boundary.

[0037] For example, the hollow boundary 211 is equivalent to the edge outline of the hollow portion 21, and the light-transmitting boundary 121 is equivalent to the edge outline of the light-transmitting area 12. Setting the shape of the light-transmitting boundary 121 to be different from the shape of the hollow boundary 211 is conducive to distinguishing the size of the first light-shielding section 22 and the second light-shielding section 23, so that the size of the first light-shielding section 22 is larger than the size of the second light-shielding section 23. Figure 1 For example, the shape of the hollow boundary 211 can be a circle, and the shape of the transparent boundary 121 can be a non-standard circle. The non-standard circle can be understood as that there is no point in the transparent area 12 with the same distance to any two points on the transparent boundary 121.

[0038] For details, please refer to Figure 1 As shown, the distances between any two points on the hollow boundary 211 and the center of the hollow portion 21 are the same; the light-transmitting boundary 121 includes a first light-transmitting boundary 121a and a second light-transmitting boundary 121b, and the distances between two points in the first light-transmitting boundary 121a and the center of the light-transmitting area 12 are different, and the distance between at least one point in the first light-transmitting boundary 121a and the center of the light-transmitting area 12 is greater than the distance between any point in the second light-transmitting boundary 121b and the center of the light-transmitting area 12.

[0039] For example, Figure 1As shown, for the hollow portion 21, the distance between any two points on the hollow boundary 211 and the center of the hollow portion 21 is the same, which is equivalent to taking the straight-line distance from any two points on the edge contour of the hollow portion 21 to the center of the hollow portion 21 as equal. It can be understood that the shape of the hollow boundary 211 is a standard circle, and the center of the hollow portion 21 can be the center of the standard circle. Correspondingly, along the thickness direction of the display panel, the through hole formed by the hollow portion 21 penetrating the display panel can be in the shape of a standard cylinder.

[0040] like Figure 1 As shown, for the light-transmitting area 12, the light-transmitting boundary 121 includes a first light-transmitting boundary 121a and a second light-transmitting boundary 121b. The first light-transmitting boundary 121a and the second light-transmitting boundary 121b are connected to form a complete light-transmitting boundary 121. The first light-transmitting boundary 121a defines the boundary of the first light-shielding subsection 22, and the second light-transmitting boundary 121b defines the boundary of the second light-shielding subsection 23. In the figure, the first light-transmitting boundary 121a is the left half of the light-transmitting boundary 121, and the second light-transmitting boundary 121b is the right half of the light-transmitting boundary 121. Figure 1 As shown, there are two points in the first light-transmitting boundary 121a with different distances from the center of the light-transmitting area, and any two points on the second light-transmitting boundary 121b have the same distances from the center of the hollow portion 21, that is, the first light-transmitting boundary 121a can be a non-standard semicircle, and the second light-transmitting boundary 121b can be a standard semicircle; that is, there are boundary points in the first light-transmitting boundary 121a that are outside the standard semicircular trajectory, and all boundary points in the second light-transmitting boundary 121b are located on the standard semicircular trajectory. Furthermore, there is at least one point in the first light-transmitting boundary 121a whose distance from the center of the light-transmitting area 12 is greater than the distance between any point in the second light-transmitting boundary and the center of the light-transmitting area 12, which is equivalent to the existence of an area in the first light-transmitting boundary 121a that exceeds the standard semicircular trajectory with the same radius as the second light-transmitting boundary 121b. It can also be understood that the first light-transmitting boundary 121a is a structure obtained by stretching the standard semicircle toward the side away from the center of the light-transmitting area 12, thereby ensuring that the size of the first light-shielding section 22 defined by the first light-transmitting boundary 121a is greater than the size of the second light-shielding section 23 defined by the second light-transmitting boundary 121b. In this way, other structures, such as an anti-static structure, can be set in the larger first light-shielding section 22 to facilitate the improvement of the function of the display module.

[0041] It should be noted that Figure 1The first light-transmitting boundary 121a is taken as the left half of the light-transmitting boundary 121, and the second light-transmitting boundary 121b is taken as the right half of the light-transmitting boundary 121 as an example for illustration only and not limitation. It can be understood that the first light-transmitting boundary can be the right half of the light-transmitting boundary, and the second light-transmitting boundary can be the left half of the light-transmitting boundary; or, the first light-transmitting boundary can be the upper half of the light-transmitting boundary, and the second light-transmitting boundary can be the lower half of the light-transmitting boundary; or, the first light-transmitting boundary can be the upper left half of the light-transmitting boundary, and the second light-transmitting boundary can be the lower right half of the light-transmitting boundary. The embodiment of the present invention does not limit the specific division method of the first light-transmitting boundary and the second light-transmitting boundary. It is only necessary to satisfy that there is at least one point in one of the two light-transmitting boundaries and the distance between it and the center of the light-transmitting area is greater than the distance between any point in the other light-transmitting boundary and the center of the light-transmitting area.

[0042] Based on the above embodiments, Figure 6 is a structural diagram of another display module provided by an embodiment of the present invention, Figure 7 yes Figure 6 A schematic diagram of a cross-sectional structure of a display module provided along the section line C-C', combined with Figure 6-Figure 7 As shown, the display panel 10 provided by the present invention also includes a transition area 13 located between the display area 11 and the light-transmitting area 12; the transition area 13 is provided with a partition groove 131, and the partition groove 131 is arranged around the light-transmitting area 12, and the groove shape of the partition groove 131 is similar to the shape of the light-transmitting boundary 121.

[0043] For example, Figure 6 and Figure 7 As shown, the display panel 10 provided by the embodiment of the present invention may further include a transition area 13 located between the display area 11 and the light-transmitting area 12, wherein a partition groove 131 is provided in the transition area 13, and the partition groove 131 is provided around the light-transmitting area 12 and passes through part of the film layer in the display panel 10, that is, the partition groove 131 forms a partition opening in part of the film layer of the display panel 10, and the partition opening may be, for example, an opening in the shape of "small at the top and large at the bottom", so that part of the film layer in the display panel 10, such as the encapsulation layer, will form a fracture at the position of the partition groove 131, thereby disconnecting the transmission path of water vapor or oxygen, thereby preventing water vapor or oxygen from extending along part of the film layer in the display panel 10 to the display area 11. In this way, the provision of the partition groove 131 can ensure that the display area 11 is protected from water and oxygen corrosion, and ensure that the display area 11 has a good and stable display effect. Optionally, as Figure 7As shown, the transition area 13 can also be provided with a retaining wall structure 132. Since the organic layer has a strong ability to absorb water and oxygen, the retaining wall structure 132 can block the organic layer in the encapsulation layer from being transmitted to the light-transmitting area 12, thereby preventing water and oxygen from being transmitted through the organic layer to the display area 11, thereby ensuring the display effect of the display area 11. Optionally, the transition area 13 can be provided with a plurality of partition grooves 131, so that the transmission path of water vapor or oxygen can be fully disconnected, thereby minimizing the possibility of water vapor or oxygen extending along part of the film layer in the display panel 10 to the display area 11. Specifically, as shown in FIG. Figure 7 As shown, at least one partition groove 131 can be set between the retaining wall structure 132 and the display area 11, and at least one partition groove 131 can be set between the retaining wall structure 132 and the light-transmitting area 12. The embodiment of the present invention does not limit the specific number of partition grooves.

[0044] Corresponding to the set shape of the light-transmitting area 12, the groove shape of the partition groove 131 can be a similar figure to the shape of the light-transmitting boundary 121. The similar figure here can be understood as the outline of the light-transmitting boundary 121 is the same as the outline shape of the partition groove 131, and the center of the light-transmitting boundary 121 coincides with the center of the partition groove 131. In this way, it is ensured that the distance between the partition groove 131 and the light-transmitting boundary 121 at each position is the same, and the partition groove 131 at each position has the same water and oxygen barrier effect, ensuring that each position of the display area 11 has a balanced display effect after passing through the partition groove 131. Specifically, when the first light-transmitting boundary 121a can be a non-standard semicircle and the second light-transmitting boundary 121b can be a standard semicircle, the shape of the partition groove 131 corresponding to surrounding the first light-transmitting boundary 121a is also a non-standard circle, and the shape of the partition groove 131 corresponding to surrounding the second light-transmitting boundary 121b is also a standard circle. The two parts of the partition groove form a complete partition groove surrounding the first light-transmitting boundary 121a.

[0045] It should be noted that when the transition zone 13 is provided with multiple partition grooves, the groove shapes of the multiple partition grooves can all be similar to the shape of the light-transmitting boundary, or at least the groove shapes of the partition grooves near the light-transmitting zone can be similar to the shape of the light-transmitting boundary. Furthermore, when the transition zone includes a retaining wall structure, the shape of the retaining wall structure can also be similar to the shape of the light-transmitting boundary, ensuring that the distance between the retaining wall structure and the light-transmitting zone is consistent at all locations.

[0046] Based on the above embodiments, Figure 8 is a structural diagram of another display module provided by an embodiment of the present invention, Figure 9 FIG. 1 is a structural diagram of another display module provided by an embodiment of the present invention. Figure 8 and Figure 9As shown, the display module further includes a signal trace 133 located in the transition region 13 and arranged around the partially transparent boundary 121 . The winding shape of the signal trace 133 arranged around the partially transparent boundary 121 is similar to the shape of the transparent boundary 121 .

[0047] For example, since display sub-pixels 111 can be provided on different sides of the light-transmitting area 12, the display panel 10 includes signal traces 133 that provide display signals to the display sub-pixels 111 on different sides of the light-transmitting area 12. Figure 8 Taking the display panel shown as an example, the signal lines 133 may include first-type signal lines 1331 extending along the row direction of the display sub-pixels 111 as a whole, such as scan lines (scan) that provide scan signals to the left and right sides of the light-transmitting area 12, emission control lines (emit) that provide emission control signals to the left and right sides of the light-transmitting area 12, and reference lines (Vref) that provide reference signals to the left and right sides of the light-transmitting area 12. Figure 9 Taking the display panel shown as an example, the signal lines 133 may include second-type signal lines 1332 that extend generally along the columns of the display sub-pixels 111. For example, these may include data lines (data) that provide data signals to the upper and lower sides of the light-transmitting area 12, voltage lines (pvdd) that provide voltage signals to the upper and lower sides of the light-transmitting area 12, etc. The embodiment of the present invention does not limit the extension direction of the signal lines 133 or the signals they transmit. However, it is certain that the display panel must have signal lines arranged around the portion of the light-transmitting boundary 121 to ensure that the display sub-pixels 111 on both sides of the light-transmitting area 12 can normally receive display signals and display.

[0048] by Figure 8 Taking the display module shown as an example, when the signal trace 133 extends along the row direction of the display sub-pixel 111 (the Y direction shown in the figure), the same signal trace 133 includes both a portion of the trace winding around the first light-transmitting boundary 121a and a portion of the trace winding around the second light-transmitting boundary 121b. At this time, the portion of the trace winding around the first light-transmitting boundary 121a in the signal trace 133 has a similar shape to the corresponding first light-transmitting boundary 121a, and the portion of the trace winding around the second light-transmitting boundary 121b has a similar shape to the corresponding second light-transmitting boundary 121b. Figure 9Taking the display module shown as an example, when the signal trace 133 extends along the column direction of the display sub-pixel 111 as a whole (the X direction as shown in the figure), the signal trace 133 includes a portion of the trace winding around the first light-transmitting boundary 121a or includes a portion of the trace winding around the second light-transmitting boundary 121b. At this time, the portion of the trace winding around the first light-transmitting boundary 121a in the signal trace 133 and the shape of the corresponding first light-transmitting boundary 121a are similar figures, or the portion of the trace winding around the second light-transmitting boundary 121b and the shape of the corresponding second light-transmitting boundary 121b are similar figures. The similar figures here can be understood as the contour of the light-transmitting boundary 121 being the same as the winding shape of the signal trace 133, and the center of the light-transmitting boundary 121 coincides with the center of the winding of the signal trace 133, thereby ensuring that the distance between the signal trace 133 and the light-transmitting boundary 121 at each position is the same. In this way, on the one hand, it is possible to avoid exposing the signal line 133 through the light-transmitting area 12, thereby preventing the signal line 133 from interfering with the normal light reception of the sensor set in the light-transmitting area 12; on the other hand, it is possible to avoid the problem of the signal line 133 being visible, thereby ensuring the normal display packaging of the display module; on the other hand, by setting the winding shape of the signal line 133 and the shape of the light-transmitting boundary 121 to be similar, it is also possible to ensure that the distance between the signal line 133 and the light-transmitting area 12 is small, that is, reducing the setting space of the transition area 13, which is beneficial to increasing the area of ​​the display area 11 and improving the display effect of the display panel.

[0049] On the basis of the above embodiments, continue to refer to Figure 1 and 3 As shown, the display module further includes a cover plate 31, and the light-shielding layer 20 is arranged on the side of the cover plate 31 facing the display panel; the display module further includes a polarizer 33 and an optical adhesive layer 32 located between the light-shielding layer 20 and the display panel, and a support layer 35 located on the side of the display panel away from the light-shielding layer 20; a support layer opening 351 is provided in the support layer 35, and along the thickness direction of the display panel (the X direction shown in the figure), the support layer opening 351 covers the light-transmitting area 12, and the opening of the support layer opening 351 The shape is similar to the light-transmitting boundary 121; an optical adhesive opening 321 is provided in the optical adhesive layer 32, and along the thickness direction of the display panel, the optical adhesive opening 321 covers the light-transmitting area 12, and the opening shape of the optical adhesive opening 321 is similar to the light-transmitting boundary 121; a polarizer opening 331 is provided in the polarizer 33, and along the thickness direction of the display panel, the polarizer opening 331 covers the light-transmitting area 12, and the opening shape of the polarizer opening 331 is similar to the light-transmitting boundary 121.

[0050] Exemplary, reference Figure 1 and Figure 3As shown, in the display module, a cover plate 31, an optical adhesive layer 32, a polarizer 33, display pixels 10, and a support layer 35 are sequentially provided along the thickness direction of the display panel (the X direction shown in the figure). Corresponding to the light-transmitting area 12 of the display panel 10, the optical adhesive layer 32, the polarizer 33, and the support layer 35 need to be provided with openings to allow sensors to be placed within the light-transmitting area 12 and the openings of each film layer, or to allow the sensors to normally receive external light. Specifically, corresponding to the light-transmitting area 12 in the display panel 10, a support layer opening 351 is provided in the support layer 35, an optical adhesive opening 321 is provided in the optical adhesive layer 32, and a polarizer opening 331 is provided in the polarizer 33. Along the thickness direction of the display panel, the polarizer opening 331 covers the light-transmitting area 12, and along the thickness direction of the display panel, the support layer opening 351 covers the light-transmitting area 12, and the opening shape of the support layer opening 351 is similar to the light-transmitting boundary 121; the optical adhesive opening 321 covers the light-transmitting area 12, and the opening shape of the optical adhesive opening 321 is similar to the light-transmitting boundary 121; the polarizer opening 331 covers the light-transmitting area 12, and the opening shape of the polarizer opening 331 is similar to the light-transmitting boundary 121. For example, the opening shapes in each film layer are non-standard circles that are asymmetric at both ends along the first direction. By setting the support layer opening 351, the optical glue opening 321 and the polarizer opening 331, and making the shape of each opening similar to the light-transmitting boundary, it can be ensured that the sensor set in the corresponding light-transmitting area 12 in the light-transmitting area 12 can receive light normally, ensure the sensor's photosensitivity detection effect, and avoid the problem of visible film layer. At the same time, it can avoid the problem that although each opening structure is set around the light-transmitting area 12, the shape of the opening has a large deviation from the shape of the light-transmitting boundary, resulting in a larger screen-to-body ratio of the non-display area, thereby improving the display effect of the display panel.

[0051] Based on the above embodiments, continue to refer to Figure 1 and Figure 3 The display panel 10 includes at least two light-transmitting areas 12 , with a non-light-transmitting area 14 disposed between two adjacent light-transmitting areas 12 ; the center of the light-transmitting area 12 is located on one side of the hollow center close to the non-light-transmitting area 14 .

[0052] For example, based on the functional requirements of the display module, such as realizing the imaging and sensing distance functions at the same time, a technical solution of multiple sensors is generally provided in the display panel 10, so there may be at least two light-transmitting areas 12 in the display panel 10 to ensure that the sensors in the light-transmitting areas 12 realize the imaging and sensing functions at the same time. In order to ensure that the sensors work independently and avoid mutual interference between two adjacent sensors, a non-light-transmitting area 14 may be provided between two adjacent light-transmitting areas 12. The non-light-transmitting area 14 may be an area where there is no light-transmitting hole, and the non-light-transmitting area 14 may not have a display function. The center of the light-transmitting area 12 is set on the side of the hollow center close to the non-light-transmitting area 14, which is equivalent to extending the light-transmitting area 12 to the side of the non-light-transmitting area 14. This ensures that the space area covered by the first light-shielding section 22 is further expanded without affecting the normal display, thereby improving the functional integration of the display module.

[0053] Optionally, two adjacent light-transmitting areas 12 are symmetrically arranged about a perpendicular bisector of a line connecting the centers of the two adjacent light-transmitting areas.

[0054] For example, the perpendicular bisector of the line connecting the centers of two adjacent light-transmitting areas is equivalent to the axis of symmetry of the two light-transmitting areas 12. Arranging the two adjacent light-transmitting areas 12 axially symmetrically can make the light-transmitting areas 12 neatly arranged, the sensors arranged in the corresponding photosensitive areas 12 neatly and symmetrically arranged, and make the appearance of the display module more neat.

[0055] Based on the above embodiment, the display area includes display sub-pixels, which include multiple layers of first film layers; the non-transparent area includes virtual sub-pixels, which include multiple layers of second film layers; at least one second film layer is arranged on the same layer as the first film layer.

[0056] Exemplarily, the display area of ​​the display module further includes a plurality of display sub-pixels, each of which includes multiple first film layers. The first film layers may include film layers in the pixel circuit and film layers in the light-emitting element, such as an active layer, a gate layer, a source / drain electrode layer, an anode layer, a light-emitting layer, and a cathode layer. A dummy sub-pixel is disposed in the non-transparent area. The dummy sub-pixel may be understood as a sub-pixel having the same film layer structure as the display sub-pixel, but without a light-emitting function. For example, some film layers in the dummy sub-pixel are not interconnected. Specifically, the dummy sub-pixel includes multiple second film layers. The second film layers may include film layers in the dummy pixel circuit and film layers in the virtual light-emitting element, such as a dummy active layer, a dummy gate layer, a dummy source / drain electrode layer, a dummy anode layer, a dummy light-emitting layer, and a dummy cathode layer. The dummy film layers are located in the same locations as the various film layers in the first film layers, but the different film layers may not be interconnected. For example, the dummy source / drain electrode layer may not be electrically connected to the dummy active layer and the dummy anode layer. In other words, the film structure between the first film layer and the second film layer here can be the same, but the spatial regions they are located in are different. The first film layer exists in the display area 11, and the second film layer exists in the non-transparent area. At least one second film layer is set on the same layer as the first film layer, so that the display sub-pixels and the virtual sub-pixels can be prepared using the same process, further reducing the preparation process and preparation cost of the display module.

[0057] In summary, the above embodiments illustrate the difference in shape between the light-transmitting area and the hollow portion, detailing the specific configuration of the light-transmitting area. Furthermore, with respect to the configuration of the light-transmitting area, further descriptions are given of the structural design of other structures in the display panel that match the configuration of the light-transmitting area. Next, another configuration of the light-transmitting area and the hollow portion is described.

[0058] Specifically, Figure 10 yes Figure 2 Schematic diagram, combined Figure 2 and Figure 10 As shown, the hollow portion 21 includes a hollow boundary 211, which defines the setting area of ​​the hollow portion 21; the light-transmitting area 12 includes a light-transmitting boundary 121, which defines the setting area of ​​the light-transmitting area 12; the shape of the light-transmitting boundary 121 is similar to the shape of the hollow boundary 211.

[0059] For example, the hollow boundary 211 corresponds to the edge contour of the hollow portion 21, and the light-transmitting boundary 121 corresponds to the edge contour of the light-transmitting area 12. The shape of the light-transmitting boundary 121 is set to be similar to the shape of the hollow boundary 211. The similar shape here can be understood as the outline of the light-transmitting boundary 121 and the outline of the hollow boundary 211 being the same, for example, both being circular, to ensure that the configuration of the light-transmitting area 12 and the hollow portion 21 is simple. In the embodiment of the present invention, as long as the shape of the light-transmitting boundary 121 is similar to that of the hollow boundary 211, the configuration area and size of the hollow portion 21 and the light-transmitting area 12 are not specifically limited.

[0060] For details, please refer to Figure 10 The shape of the light-transmitting boundary 121 and the shape of the hollow boundary 211 are both circular; the radius of the hollow boundary 211 is R1, and the radius of the light-transmitting boundary 121 is R2; along the first direction, the distance L between the center of the hollow portion and the center of the light-transmitting portion is ≤ R2-R1.

[0061] Exemplarily, the radius of the hollow boundary 211 is set to R1, the radius of the light-transmitting boundary 121 is set to R2, and the distance between the center of the hollow portion 21 and the center of the light-transmitting area 12 is set to L. When L≤R2-R1 along the first direction, the maximum offset distance between the center of the hollow portion 21 and the center of the light-transmitting area 12 is equivalent to the difference between the radii of the two. This ensures that the exposed area of ​​the hollow portion 21 will not extend to the area outside the light-transmitting area 12, while also enabling other structures to be set in the larger shading section to achieve the effect of improving the functional integration of the display module.

[0062] Based on the same inventive concept, an embodiment of the present invention further provides a display device, Figure 11 is a structural diagram of a display device provided by an embodiment of the present invention, such as Figure 11 As shown, the display device 1 includes the display module 100 described in any of the above embodiments.

[0063] For details, please refer to Figure 11 As shown, the display device 1 further includes a sensor 2; the sensor 2 is provided corresponding to the light-transmitting area 12, such as an optical sensor or a distance sensor, for realizing other additional functions of the display device, such as imaging or sensing distance, which is not limited in this embodiment of the present invention.
