[0040] Figure 1 The figure shows a cross-sectional structure diagram of a display module provided by the related art. Figure 1 As shown, the display module provided by the related technology includes a display panel, a first support member, a light-sensing structure, a second support member, and a circuit board, wherein the first support member is stacked between the second support member and the circuit board, the first support member encloses to form a receiving space, and the light-sensing structure is located in the receiving space.

[0041] In the display module provided by the relevant technology, the inventors found through in-depth research that due to the small attachment area between the first support member and the second support member and the easy displacement during attachment, the first support member is easily loosely attached and the first support member is lifted up and leaks light; and the second support member blocks the light that the photosensitive structure should receive, resulting in insufficient light receiving rate of the photosensitive structure, which fails to meet the requirements of the photosensitive performance test.

[0042] In order to solve the above technical problems, an embodiment of the present application provides a display module, which includes a display panel, a first support member and a light-sensing structure; the first support member is located on the non-display side of the display panel, and the first support member encloses a receiving space. By directly attaching the first support member to the display panel, the light leakage problem is improved; the light-sensing structure is located on the non-display side of the display panel and within the receiving space; wherein the first support member has an inner wall facing the receiving space, and the inner wall is inclined in a direction away from the light-sensing structure in a direction from the light-sensing structure to the display panel, thereby improving the problem of light blocking by the first support member and the second support member, thereby improving the light collection rate of the light-sensing structure, so that the light-sensing structure meets the requirements of the light-sensing performance test.

[0043] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present application and are not configured to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is merely to provide a better understanding of the present application by illustrating the examples of the present application.

[0044] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element.

[0045] It should be understood that when describing the structure of a component, when a layer or a region is referred to as being "on" or "over" another layer or region, it may mean that it is directly on the other layer or region, or that other layers or regions are included between it and the other layer or region. Furthermore, if the component is turned over, the layer or region will be "below" or "beneath" the other layer or region.

[0046] In a first aspect, the present application provides a display module. Figure 2 FIG. 1 is a schematic diagram of the cross-sectional structure of a display module provided by an embodiment of the present application. Figure 2As shown, the display module 100 includes a display panel 110, a first support member 120, and a light sensing structure 130. The display panel 110 has a display side and a non-display side disposed opposite each other along its thickness direction X. The first support member 120 is located on the non-display side of the display panel 110 and is connected to the display panel 110, optionally by adhesive bonding. The first support member 120 encloses a receiving space S. The light sensing structure 130 is located on the non-display side of the display panel 110 and within the receiving space. The first support member 120 has an inner wall P1 facing the receiving space. The inner wall P1 is inclined away from the light sensing structure 130 in the direction from the light sensing structure 130 to the display panel 110. That is, the angle between the inner wall P1 and the display panel 110, facing the side of the receiving space S, is an acute angle. The cross-sectional area of the receiving space S on the side closest to the display panel 110 is larger than the cross-sectional area on the side away from the display panel 110, resulting in the receiving space S having a structural form, such as an inverted terrace or a frustum.

[0047] The first support member 120 may be made of foam adhesive and serves to support and secure the light sensing structure 130. The first support member 120 is attached to the non-display side of the display panel 110 and in contact with the non-display side of the display panel 110, providing light shielding and protection. This reduces the impact of ambient light on the light sensing structure 130, and also mitigates the issue of light that would otherwise enter the accommodation space S and illuminate the light sensing structure 130 being blocked due to misalignment of the first support member 120. This also mitigates the issue of low light collection efficiency of the light sensing structure 130.

[0048] The embodiment of the present application improves the light leakage problem by directly attaching the first support member 120 to the display panel 110, and sets the inner wall P1 to be inclined, thereby improving the problem of the first support member 120 and the second support member blocking light, thereby improving the light collection rate of the light sensing structure 130, so that the light sensing structure 130 meets the requirements of the light sensing performance test.

[0049] Figure 3 FIG. 1 is a schematic diagram of a cross-sectional structure of a display module provided by another embodiment of the present application. Figure 3 As shown, according to the implementation of the first aspect of the present application, the display module 100 also includes a second support member 140, which is located on the non-display side of the display panel 110 and is connected to the display panel 110, and can be optionally adhesively connected. The second support member 140 includes an opening, and the orthographic projection of the opening on the display panel 110 covers the orthographic projection of the side surface of the first support member 120 facing the display panel 110 on the display panel 110.

[0050] The second support member 140 supports the display panel 110 and buffers the force applied to the display panel 110 .

[0051] The provision of the second support member 140 enhances the overall structural stability of the display module 100 . In particular, for a large-sized or curved display panel 110 , the second support member 140 can provide additional support to reduce bending or deformation of the display module 100 .

[0052] The opening design of the second support member 140 ensures that light can smoothly enter the light sensing structure 130 , reducing the possibility of the first support member 120 and the second support member 140 blocking light, thereby improving the light collection rate and light sensing performance of the light sensing structure 130 .

[0053] Optionally, the outer boundary of the second support member 140 is flush with the boundary of the display panel 110, that is, the outer boundary of the second support member 140 and the boundary of the display panel 110 can be located in the same plane. It is understood that the boundary of the second support member 140 can be arranged to conform to the boundary of the display panel 110. In an embodiment where the boundary of the display panel 110 extends along a curved surface, the boundary of the second support member 140 can be located within the same curved surface.

[0054] The embodiments of the present application have at least the following advantages: First, the edges of the display module 100 are made neater and more beautiful, thereby improving the appearance quality of the display module 100; second, the outer boundary of the second support member 140 is flush with the boundary of the display panel 110, which increases the structural stability of the display module 100 and reduces the bending or deformation of the edge portion; third, the flush design can protect the edge of the display panel 110 from physical damage, which is especially important for the display module 100 with a borderless design; fourth, during the installation process, the outer boundary of the second support member 140 is flush with the boundary of the display panel 110, which can more easily achieve precise docking with other components or housings, thereby simplifying the installation process; fifth, for application scenarios that require waterproofing or dustproofing, the flush boundary design helps to improve the sealing and prevent moisture or dust from entering the interior of the display module 100.

[0055] Optionally, the material of the second supporting member 140 includes at least one of foam glue and polyethylene terephthalate (PET).

[0056] According to the implementation of the first aspect of the present application, the orthographic projection of the second support member 140 on the display panel 110 is spaced apart from the orthographic projection of the first support member 120 on the display panel 110 .

[0057] The second support member 140 and the first support member 120 are both disposed on the non-display side of the display panel 110, and the first support member 120 partially extends into the opening of the second support member 140, passing through the opening to connect to the display panel 110. Thus, the area of the opening can be adjusted accordingly based on the size of the end portion of the first support member 120 facing the display panel 110, so that the second support member 140 and the first support member 120 are spaced apart. Furthermore, the orthographic projection of the second support member 140 on the display panel 110 can be spaced apart from the orthographic projection of the first support member 120 on the display panel 110. This provides an assembly gap for assembling the two support members, accommodating alignment errors and facilitating the processing of the display module 100.

[0058] Alternatively, refer to Figure 3 According to the implementation of the first aspect of the present application, the contact surface Q between the second support member 140 and the first support member 120 is inclined in a direction away from the light sensing structure 130 in a direction from the light sensing structure 130 to the display panel 110 .

[0059] The embodiments of the present application have at least the following advantages: First, by setting an inclined contact surface Q, the structural stability of the display module 100 can be enhanced while ensuring the light-sensing performance of the light-sensing structure 130, reducing stress concentration at the edge portion, and reducing the possibility of bending or deformation of the display panel 110; Second, the inclined contact surface Q helps to achieve a more compact and thinner design, which is particularly important for products that pursue an ultra-thin appearance; Third, the inclined contact surface Q simplifies the connection process between the first support member 120 and the second support member 140, thereby improving the efficiency of manufacturing and assembly.

[0060] refer to Figure 2 and Figure 3 According to the implementation of the first aspect of the present application, the first support member 120 has a constant wall thickness, and the first support member 120 has an outer wall P2 facing away from the accommodating space, and the outer wall P2 is parallel to the inner wall P1.

[0061] The uniform wall thickness ensures uniform mechanical strength throughout the entire length of the first support member 120, thereby improving the structural stability of the display module 100 and reducing bending or deformation at the edges. The uniform wall thickness and parallel outer wall P2 and inner wall P1 simplify the manufacturing process of the first support member 120, improving production efficiency and reducing production costs.

[0062] Of course, in other embodiments, the outer wall P2 may not be parallel to the inner wall P1. Figure 4 FIG. 1 is a schematic diagram of a cross-sectional structure of a display module provided by another embodiment of the present application, as shown in FIG. Figure 4 As shown, the outer wall P2 and the inner wall P1 are not parallel, and the extension planes of the two intersect. Figure 4The illustrated embodiment reduces the manufacturing difficulty and also reduces the requirements for manufacturing precision.

[0063] According to the implementation scheme of the first aspect of the present application, along the first direction, the light sensing structure 130 has a first light receiving angle, and along the second direction, the light sensing structure 130 has a second light receiving angle, and the first support member 120 includes two first walls arranged opposite to each other in the first direction and two second walls arranged opposite to each other in the second direction, and the first direction, the second direction and the thickness direction are arranged to intersect in pairs; the first light receiving angle is smaller than the second light receiving angle, and the angle between the first wall and the thickness direction X is smaller than the angle between the second wall and the thickness direction X.

[0064] Optionally, the inclination angles of the walls of the first support member 120 in various directions may be the same or different, and may be specifically set based on the light collection angle of the light sensing structure 130 in the corresponding direction. For example, if the cross-section of the first support member 120 is a rectangular ring, the first support member 120 may have two first walls arranged opposite each other in the first direction and two second walls arranged opposite each other in the second direction. The first walls and second walls are respectively connected to adjacent walls and are arranged alternately in the circumferential direction of the accommodating space S.

[0065] Furthermore, the inclination angles of the first wall and the second wall can be set according to the light receiving angle of the light sensing structure 130. Taking the example that the first light receiving angle of the light sensing structure 130 in the first direction is smaller than the second light receiving angle in the second direction, the inclination degree of the first wall can be smaller than the inclination degree of the second wall, that is, the angle between the first wall and the thickness direction X is smaller than the angle between the second wall and the thickness direction X. If the first light receiving angle is smaller than a certain numerical threshold, the first wall can be selected to be parallel to the thickness direction X.

[0066] By designing a method of setting the inclination of the wall according to the size of the light collection angle, the space required for the first support member 120 can be reduced while ensuring the light collection effect.

[0067] Preferably, the first light collection angle is α1, the second light collection angle is α2, 45°≤α1≤150°, and 45°≤α2≤150°.

[0068] The first and second light collection angles can be specifically between 45° and 150°, for example, any one of 45°, 60°, 75°, 90°, 105°, 120°, 135°, and 150°, or any two thereof. By setting the light collection angles within this range, the light sensing structure 130 can have good light sensing performance and facilitate setting the size of the first support member 120.

[0069] Preferably, 105°≤α1≤135°, 105°≤α2≤135°.

[0070] Furthermore, the first light receiving angle and the second light receiving angle can be between 105° and 135°, for example, any one of 105°, 110°, 115°, 120°, 125°, 130°, 135° or between any two of them, and the first light receiving angle and the second light receiving angle can be further selected to be around 120°.

[0071] Figure 5 FIG. 1 is a schematic diagram of a cross-sectional structure of a display module provided by another embodiment of the present application. Figure 5 As shown, according to the implementation of the first aspect of the present application, the display module 100 also includes a circuit board 150, the first support member 120 is connected between the circuit board 150 and the display panel 110, and the light sensing structure 130 is arranged on the side of the circuit board 150 facing the display panel 110.

[0072] The circuit board 150 serves as a platform for signal transmission and can ensure the transmission of signals from the external controller to the display panel 110, including drive signals, control signals, etc. The circuit board 150 provides the necessary power to the display panel 110 to ensure the normal operation of the display panel 110. The circuit board 150, together with the first support member 120, provides structural support for the display panel 110, helping to enhance the structural stability of the display module 100 and reduce the possibility of bending or deformation of the display panel 110. The circuit board 150, together with the first support member 120, provides additional protection for the display panel 110, especially during transportation and installation, reducing the risk of physical damage to the display panel 110.

[0073] Disposing the light sensing structure 130 on the side of the circuit board 150 facing the display panel 110 helps ensure the accurate position of the light sensing structure 130 , enabling the light sensing structure 130 to effectively receive light, thereby improving light sensing performance.

[0074] refer to Figure 5 Preferably, the orthographic projection of the contact surface between the first support member 120 and the circuit board 150 on the display panel 110 is located within the orthographic projection of the circuit board 150 on the display panel 110 .

[0075] The embodiment of the present application helps to ensure a more stable connection between the first support member 120 and the circuit board 150 , reduces stress concentration at the connection, and improves the structural stability of the display module 100 .

[0076] refer to Figure 5 According to the implementation of the first aspect of the present application, a photosensor point 131 is provided on the side of the light-sensing structure 130 facing the display panel 110, and the orthographic projection of the photosensor point 131 on the display panel 110 is concentrically arranged with the orthographic projection of the accommodating space S on the display panel 110.

[0077] The light sensing structure 130 includes a light sensing point 131 , and the orthographic projection of the light sensing point 131 on the display panel 110 coincides with the orthographic projection of the center of the accommodation space on the display panel 110 .

[0078] By aligning the orthographic projection of photosensor point 131 with the orthographic projection of the center of the accommodation space, the embodiment of the present application ensures that photosensor point 131 is in the optimal light-receiving position, reducing the possibility of light being blocked, thereby improving the light-collecting efficiency of light-sensing structure 130. Furthermore, this design helps optimize the optical path, ensuring that light can reach photosensor point 131 more directly, thereby improving the sensitivity and response speed of light-sensing structure 130.

[0079] refer to Figure 5 Preferably, the orthographic projection of the light sensing structure 130 on the display panel 110 , the orthographic projection of the light sensing point 131 on the display panel 110 , and the orthographic projection of the accommodation space S on the display panel 110 are concentrically arranged.

[0080] The location of the photosensor 131 at the center of the accommodation space and at the center of the photosensitive structure 130 helps protect the photosensor 131 from physical damage, especially during transportation and installation, reducing the risk of the photosensor 131 being squeezed or collided.

[0081] The structure of the display module 100 provided in this application has been described in detail above. The following describes a method for determining the design parameters of the first support member 120 in the display module 100. It will be appreciated that this determination method corresponds to the structure of the first support member 120. Therefore, the structure mentioned in this determination method can refer to the above-mentioned content of the display module 100 and will not be further described here.

[0082] According to the embodiment of the first aspect of the present application, the minimum distance between the surface of the first support member 120 facing the circuit board 150 and the edge of the circuit board 150 is gap1, and the minimum distance between the surface of the first support member 120 facing the circuit board 150 and the light sensing structure 130 is gap2;

[0083] 0.2mm≤gap1≤0.3mm, 0.2mm≤gap2≤0.3mm.

[0084] The minimum distance between the side surface of the first support member 120 facing the circuit board 150 and the edge of the circuit board 150, and the minimum distance between the side surface of the first support member 120 facing the circuit board 150 and the light sensing structure 130 can both be in the range of 0.2mm to 0.3mm, for example, any one of 0.2mm, 0.23mm, 0.26mm, 0.29mm, 0.3mm or between any two of them.

[0085] By making the distances between gap1 and gap2 within the aforementioned range, a certain amount of space for accommodating alignment errors can be provided, which facilitates the assembly of the circuit board 150, the light-sensing structure 130 and the first support member 120, that is, it can reduce the difficulty of installation and make the size of the first support member 120 within an appropriate range.

[0086] According to the implementation of the first aspect of the present application, along the thickness direction X, the distance between the circuit board 150 and the display panel 110 is H2, and the extended dimension of the light sensing structure 130 is H1;

[0087] H2>H1, 0.5mm≤H1≤1mm, 0.5mm≤H2≤1mm.

[0088] The spacing between the circuit board 150 and the display panel 110 in the thickness direction X and the extension dimension of the light sensing structure 130 along the thickness direction X can both be between 0.5 mm and 1 mm, for example, any one of 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm or between any two thereof.

[0089] By ensuring that the distance between the circuit board 150 and the display panel 110 is greater than the extended dimension of the light sensing structure 130, the light sensing structure 130 can be completely accommodated within the accommodation space S, preventing interference between the light sensing structure 130 and the layer structures of the display panel 110. Furthermore, by ensuring that both are within the aforementioned ranges, the overall thickness of the display module 100 can be kept within an appropriate range while providing sufficient space for the light sensing structure 130.

[0090] Preferably, along the first direction, the light sensing structure 130 has a first light collection angle α1, the first support member 120 includes two first walls arranged opposite to each other, and the distance between the orthographic projection of the light sensing point 131 on the display panel 110 and the end of the first wall close to the display panel 110 is L2;

[0091]

[0092] Through the aforementioned calculation method, the area of the end of the accommodating space S facing the display panel 110 can be adapted to the light collection angle of the light sensing structure 130, thereby reducing the space required for the first support member 120 while maintaining a good light collection efficiency. It will be understood that the first direction here is only an example, and in other directions, the distance between the orthographic projection of the light sensing point 131 on the display panel 110 and the end of the first wall closest to the display panel 110 in that direction can be correspondingly adapted to the light collection angle in that direction.

Figure 6 As shown, an embodiment of the second aspect of the present application provides a method for determining design parameters of a first support member. The first support member 120 is located in the display module 100 provided in any of the above embodiments. The design parameters include an inclination angle θ, which is the angle between the inner wall P1 of the first support member 120 and the display panel 110. Please refer to Figure 5 , the determination method includes the following steps:

[0094] Step S601, obtaining a preset thickness H1 of the light sensing structure 130 in the thickness direction of the display panel 110 (refer to Figure 5 , the same below), a first preset distance H2 between the surface of the display panel 110 close to the light sensing structure 130 and the surface of the light sensing structure 130 away from the display panel 110, a second preset distance W2 between the orthographic projection of the light sensing point 131 of the light sensing structure 130 on the display panel 110 and the edge of the orthographic projection of the light sensing structure 130 on the display panel 110, a third preset distance Gap2 between the edge of the orthographic projection of the light sensing structure 130 on the display panel 110 and the inner edge of the orthographic projection of the inner wall P1 of the first support member 120 on the display panel 110, and a preset light collection angle α of the light sensing structure 130.

[0095] Step S602, determining a fourth preset distance L2 between the orthographic projection of the light-sensing point 131 of the light-sensing structure 130 on the display panel 110 and the outer edge of the orthographic projection of the inner wall P1 of the first support member 120 on the display panel 110, wherein:

[0096] Step S603 : determining a fifth preset distance L3 between the inner edge and the outer edge of the orthographic projection of the inner wall P1 of the first support member 120 on the display panel 110 , where L3 = L2 − Gap2 − W2 .

[0097] Step S604, determining the tilt angle θ, where:

[0098] Figure 7 FIG. 1 is a flow chart of a method for determining design parameters of a first support member according to an embodiment of the present application. Figure 7 As shown, according to the embodiment of the second aspect of the present application, the design parameter further includes the extension length of the first support member 120, and the determination method further includes the following steps:

[0099] Step S701: Determine the extension length L1 based on the fifth preset distance L3 and the first preset distance H2, wherein:

[0100] Figure 8 FIG. 1 is a flow chart of a method for determining design parameters of a first support member according to an embodiment of the present application. Figure 8As shown, according to an embodiment of the second aspect of the present application, the design parameters further include the wall thickness of the first support member 120, the display module 100 further includes a circuit board 150, the first support member 120 is connected between the circuit board 150 and the display panel 110, and the light sensing structure 130 is disposed on a side of the circuit board 150 facing the display panel 110. The determination method further includes the following steps:

[0101] Step S801, obtaining a sixth preset distance Gap3 (reference distance Gap3) between the edge of the positive projection of the light sensing structure 130 on the display panel 110 and the edge of the positive projection of the circuit board 150 on the display panel 110. Figure 5 , the same below), a seventh preset distance Gap1 between an edge of the circuit board 150 projected on the display panel 110 and an inner edge of the outer wall P2 of the first support member 120 projected on the display panel 110.

[0102] Step S802 : Determine the wall thickness W1 based on the sixth preset distance Gap3 , the seventh preset distance Gap1 , and the third preset distance Gap2 , wherein W1 = Gap3 − Gap1 − Gap2 .

[0103] The method for determining the design parameters of the first support member 120 provided in this application obtains the inclination angle, extension length and wall thickness of the first support member 120, thereby maximizing the use of limited space, increasing the attachment area between the first support member 120 and the display panel 110, thereby enhancing the attachment effect of the first support member 120 and the display panel 110, and improving the problem of light leakage caused by the first support member 120 tilting, thereby improving the light collection rate and sensitivity of the light-sensing structure 130.

[0104] In addition, when the related technology determines the extension length and wall thickness of the first support member 120, it is necessary to consider the dimensional tolerance and process matching accuracy between it and the second support member 140. Therefore, the design parameters of the first support member 120 obtained by the related technology are easily affected by the dimensional error of the second support member 140, resulting in the first support member 120 and the second support member 140 in the related technology having low matching accuracy and poor attachment effect between the two.

[0105] However, in the determination method provided in the present application, the design parameters of the first support member 120 are not affected by the size of the second support member 140 , thereby improving the accuracy of the design parameters of the first support member 120 .
