Description

Technical Field

[0001] This application relates to the field of display technology, and more specifically to a display module and a display device. Background Technology

[0002] In existing display technologies, front-facing recognition has become a mainstream requirement for display devices. To achieve aesthetic appeal and increase the display area, perforations are typically incorporated into the display screen to house the recognition device. A shielding layer is usually required in the bezel area outside the perforation area to conceal the wiring, resulting in high visibility of the bezel area. This leads to a significant visual contrast between the bezel area and the display area outside the bezel during display, thus reducing the overall display quality.

[0003] Reducing the visual contrast between the outer edge of the hole area and the display area outside the edge is an important condition for ensuring good display effect. Summary of the Invention

[0004] In view of this, this application provides a display module and a display device to help solve the problem of reduced screen display effect.

[0005] In a first aspect, embodiments of this application provide a display module, which includes a first region and at least one second region. The first region includes a first display area and a first border area, the first display area at least partially surrounding the second region, and the first border area located on the side of the first display area away from the second region. The second region includes a light-transmitting functional area and a second border area, the light transmittance of the light-transmitting functional area being greater than the light transmittance of the first display area, and the second border area located between the first display area and the light-transmitting functional area. The first region includes a first light-shielding structure, the second border area includes a second light-shielding structure, the light density value of the first light-shielding structure is OD1, the light density value of the second light-shielding structure is OD2, and OD1 > OD2.

[0006] Secondly, embodiments of this application provide a display device, including the display module as described in the first aspect.

[0007] In this embodiment, the first region includes a first light-shielding structure, and the second border region includes a second light-shielding structure. The light density value OD1 of the first light-shielding structure is greater than the light density value OD2 of the second light-shielding structure. This arrangement allows the light transmittance of the second light-shielding structure to be greater than that of the first light-shielding structure. The greater the light transmittance of the light-shielding structure, the lower the visibility of the region where the light-shielding structure is located. By setting OD1 > OD2, the visibility of the second border region is made weaker than that of the first display region, thus reducing the visual contrast between the second border region and the first display region, thereby improving the user's visual experience.

[0021] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0022] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0023] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0024] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0025] Figure 1 This is a schematic diagram of a partial structure of a display module related to this application.

[0026] like Figure 1 As shown, the display module 10' includes a first display area AA, a border area B, and a light-transmitting functional area S. The first display area AA at least partially surrounds the border area B, and the border area B at least partially surrounds the light-transmitting functional area S. The light-transmitting functional area S is used to house an identification device R, wherein the identification device R may include a biometric identification device and an image recognition device, and the identification device R can be used to identify images or the biometric features of a user. Specifically, the identification device R may be at least one of optical sensors such as a camera, a fingerprint recognition sensor, or a facial recognition sensor.

[0027] Some traces in the display module 10' bypass the light-transmitting functional area S and are located in the bezel area B. To prevent the traces in bezel area B from affecting the visual effect, a light-shielding structure C is set in bezel area B to block the traces located in bezel area B. The light-transmitting functional area S is usually wider along a specific direction, resulting in an increased number of traces bypassing the light-transmitting functional area S, and thus a larger area for the traces in bezel area B. Because the light-shielding structure C blocks the trace area in bezel area B, the projected area of ​​the light-shielding structure C on the plane of the display module 10' is large. During display, the visual effect contrast between the low-light-transmitting area in bezel area B and the first display area AA is obvious. Specifically, the obvious black border around the light-transmitting functional area S affects the viewing effect.

[0028] Figure 2This is a schematic diagram of a partial structure of a display module provided in an embodiment of this application. Figure 3 This is a schematic diagram of a partial structure of a display module provided in an embodiment of this application.

[0029] To address the aforementioned problems, this application provides a display module 10, which includes a first region A1 and at least one second region A2. For example, as Figure 2 As shown, the display module 10 includes a first region A1 and a second region A2. For example, as... Figure 3 As shown, the display module 10 includes a first region A1 and two second regions A2.

[0030] Figure 4 This is a schematic diagram of a partial structure of a display module provided in an embodiment of this application.

[0031] like Figures 2-4 As shown, the first region A1 includes a first display area AA and a first border area B1, with the first display area AA at least partially surrounding the second region A2. For example, as... Figure 4 As shown, along a direction perpendicular to the plane where the display module 10 is located, the orthographic projection of the first display area AA surrounds the orthographic projection of the second area A2.

[0032] The first border area B1 is located on the side of the first display area AA that is furthest from the second area A2, such as... Figure 4 As shown, along a direction perpendicular to the plane where the display module 10 is located, the orthographic projection of the first bezel area B1 surrounds the orthographic projection of the first display area AA. The first bezel area B1 can be the area surrounding the display panel used for encapsulation and setting of peripheral circuits and signal lines.

[0033] like Figure 4 As shown, the second region A2 includes a light-transmitting functional area S, whose light transmittance is greater than that of the first display area AA. Since the recognition device R is housed in the light-transmitting functional area S, and the recognition device R requires a high light transmittance during normal operation, the light transmittance of the light-transmitting functional area S is greater than that of the first display area AA. For example, no pixels may be set in the second region A2, or the pixel density in the second region A2 may be less than the pixel density in the first display area AA.

[0034] The second region A2 also includes the second border region B2, such as Figure 4 As shown, the second border area B2 is located between the first display area AA and the light-transmitting functional area S. The second border area B2 can contain traces L or circuits that bypass the light-transmitting functional area S; furthermore, when no pixels are set in the light-transmitting functional area S, a portion of the functional film layer of the display module 10 can be removed from the light-transmitting functional area S.

[0035] The first region A1 includes a first light-shielding structure C1, and the second border region B2 includes a second light-shielding structure C2. The first light-shielding structure C1 can be used to block at least one of the aforementioned traces, circuits, reflective structures, etc., in the first region A1. The second light-shielding structure C2 is used to block at least one of the aforementioned traces, circuits, etc., in the second border region B2. The optical density value of the first light-shielding structure C1 is OD1, and the optical density value of the second light-shielding structure C2 is OD2, where OD1 > OD2. The magnitude of the optical density value represents the light transmittance of the material. When the optical density value of the material is higher, the light transmittance of the material is lower, and the visibility is stronger; when the optical density value of the material is lower, the light transmittance of the material is stronger, and the visibility is weaker. When OD1 > OD2, the visibility of the second light-shielding structure C2 is weaker than that of the first light-shielding structure C1.

[0036] In this embodiment, by setting OD1 > OD2, the visibility of the second light-shielding structure C2 is lower than that of the first light-shielding structure C1 in the first display area AA. Since the second light-shielding structure C2 is located in the second border area B2, the visibility of the second border area B2 is also reduced. During the display process of the display module 10, the reduced visibility of the second border area B2 reduces the visual contrast between the second border area B2 and the first display area AA, thereby improving the user's visual experience.

[0037] In one embodiment of this application, OD1 > 3, 1 ≤ OD2 ≤ 3.

[0038] In this embodiment, when OD1 > 3, the first light-shielding structure C1 has a low light transmittance, which helps to block at least one of the traces, circuits, reflective structures, etc. in the first area A1, thereby improving the visual effect. If OD2 < 1, the second light-shielding structure C2 is not ideal in blocking the traces L, circuits, etc. in the second frame area B2; if OD2 > 3, the visibility of the second light-shielding structure C2 is strong. Considering both the visibility and blocking ability of the second light-shielding structure C2, selecting OD2 that satisfies 1 ≤ OD2 ≤ 3 can both reduce the visibility of the second light-shielding structure C2, weakening the visual effect difference between the second frame area B2 and the first display area AA, and also allow the second light-shielding structure C2 to meet the blocking requirements for the traces L, circuits, and other structures in the second frame area B2.

[0039] Figure 5 This is a schematic diagram of a partial structure of a display module provided in an embodiment of this application.

[0040] In one embodiment of this application, within the same second region A2, the second border region B2 includes a first sub-border region B21 and a second sub-border region B22. For example... Figure 5As shown, the same second border area B2 may include two first sub-border areas B21 and two second sub-border areas B22. The two first sub-border areas B21 are arranged opposite to each other, and the two second sub-border areas B22 are arranged opposite to each other. The maximum distance between the edge of the first sub-border area B21 furthest from the light-transmitting functional area S and the light-transmitting functional area S is d1, and the maximum distance between the edge of the second sub-border area B22 furthest from the light-transmitting functional area S and the light-transmitting functional area S is d2, where d1 is greater than d2.

[0041] like Figure 5 As shown, the traces L that bypass the light-transmitting functional area S generally extend along the second direction Y and are arranged along the first direction X, with the first direction X intersecting the second direction Y. These traces L are arranged side-by-side and wound around the first sub-border area B21 along the first direction X. However, these traces L are not concentrated in the second sub-border area B22 to wound along the second direction. Therefore, the maximum length of the trace area along the first direction X in the first sub-border area B21 is greater than the maximum length of the trace area along the second direction Y in the second sub-border area B22.

[0042] To shield the wiring area in the second frame area B2, the first width of the second light-shielding structure C2 needs to be greater than its second width. The first width refers to the maximum length between the edge of the second light-shielding structure C2 located within the first sub-frame area B21 and the light-transmitting functional area S; the second width refers to the maximum length between the edge of the second light-shielding structure C2 located within the second sub-frame area B22 and the light-transmitting functional area S.

[0043] For example, such as Figure 5 As shown, along the direction perpendicular to the plane where the display module 10 is located, the orthographic projection of the second light-shielding structure C2 coincides with the orthographic projection of the second border area B2. Therefore, the first width is equal to d1 and the second width is equal to d2. Since d1 > d2, the first width is greater than the second width.

[0044] The optical density value of the portion of the second light-shielding structure C2 located within the first sub-border area B21 is OD21, and the optical density value of the portion of the second light-shielding structure C2 located within the second sub-border area B22 is OD22, where OD21 < OD22. The visibility of the portion of the second light-shielding structure C2 located within the first sub-border area B21 is weaker than the visibility of the portion of the second light-shielding structure C2 located within the second sub-border area B22.

[0045] In the prior art, if the first width is greater than the second width, the visual difference between the first sub-border area B21 and the first display area AA is significantly greater than the visual difference between the second sub-border area B22 and the first display area AA. To make the visual difference between each part of the second border area B2 and the first display area AA approximately the same, OD21 < OD22 is set, so that the visibility of the first sub-border area B21 is weaker than the visibility of the second sub-border area B22.

[0046] Figure 6 This is a schematic diagram of a partial structure of a display module provided in an embodiment of this application.

[0047] In one embodiment of this application, the display module 10 includes at least two second regions A2, and the at least two second regions A2 include a first sub-region A21 and a second sub-region A22. For example, as Figure 6 As shown, the display module 10 includes two second regions A2, each of which includes a first sub-region A21 and a second sub-region A22. The first sub-region A21 includes a first light-transmitting functional area Sa, and the second sub-region A22 includes a second light-transmitting functional area Sb. Since the area of ​​the light-transmitting functional area S included in the first sub-region A21 is larger than the area of ​​the light-transmitting functional area Sb included in the second sub-region A22, the area of ​​the first light-transmitting functional area Sa is larger than the area of ​​the second light-transmitting functional area Sb.

[0048] The maximum optical density value of the second light-shielding structure C2 included in the first sub-region A21 is less than the minimum optical density value of the second light-shielding structure C2 included in the second sub-region A22, and the visibility of the second light-shielding structure C2 included in the first sub-region A21 is weaker than the visibility of the second light-shielding structure C2 included in the second sub-region A22. For example... Figure 6 As shown, the first sub-shading structure C2a is the second shading structure C2 included in the first sub-region A21, and the second sub-shading structure C2b is the second shading structure C2 included in the second sub-region A22. Therefore, the visibility of the first sub-shading structure C2a is weaker than the visibility of the second sub-shading structure C2b.

[0049] In this embodiment, the larger the area of ​​the light-transmitting functional area S in the display module 10, the larger the number of traces that bypass the light-transmitting functional area S. Since the area of ​​the first light-transmitting functional area Sa is larger than the area of ​​the second light-transmitting functional area Sb, the number of traces M that bypass the first light-transmitting functional area Sa is greater than the number of traces N that bypass the second light-transmitting functional area Sb. Since M > N, the width of the first sub-light-shielding structure C2a is greater than the width of the second sub-light-shielding structure C2b. The larger the width of the second light-shielding structure C2, the more obvious the visual effect difference between the area where the second light-shielding structure C2 is located and the first display area AA. Making the visibility of the first sub-light-shielding structure C2a weaker than that of the second sub-light-shielding structure C2b can reduce the difference in visual effect between the second light-shielding structure C2 in different second areas A2 and the first display area AA, thereby improving the display effect.

[0050] Figure 7 This is a schematic diagram of a partial structure of a display module provided in an embodiment of this application. Figure 8 for Figure 7 The diagram shows a cross-sectional view of the display module along the AA' direction.

[0051] In one embodiment of this application, along a direction perpendicular to the surface of the display module 10, the thickness of the first light-shielding structure C1 is h1, and the thickness of the second light-shielding structure C2 is h2, wherein h1 > h2. Combined with... Figure 7 and Figure 8 The first frame area B1 includes a first light-shielding structure C1, and the second frame area B2 includes a second light-shielding structure C2. Along a direction perpendicular to the surface of the display module 10, the thickness h1 of the first light-shielding structure C1 is greater than the thickness h2 of the second light-shielding structure C2, so that the optical density value OD1 of the first light-shielding structure C1 is greater than the optical density value OD2 of the second light-shielding structure C2, and the visibility of the first light-shielding structure C1 is stronger than the visibility of the second light-shielding structure C2.

[0052] In this embodiment, by setting h1 > h2, the visibility of the second light-shielding structure C2 is weaker than that of the first light-shielding structure C1. Compared to the visual effect contrast between the first border area B1 and the first display area AA, the visual effect contrast between the second border area B2 and the first display area AA is not obvious. Since the second border area B2 is located in the display area, this helps to improve the display effect of the display module 10.

[0053] In one implementation, the first light-shielding structure C1 and the second light-shielding structure C2 are made of the same material and h1 > h2.

[0054] In one embodiment of this application, 0.4um≤h2≤1um, 1um

[0055] ​In this embodiment, since h2 ≤ 1µm and 1µm < h1 (i.e., h1 > h2), the visibility of the second light-shielding structure C2 is weaker than that of the first light-shielding structure C1. When h2 = 0.4µm and h1 = 1.5µm, the difference between the visibility of the second light-shielding structure C2 and the first light-shielding structure C1 is relatively large. Compared to the visual effect contrast between the first border area B1 and the first display area AA, the visual effect contrast between the second border area B2 and the first display area AA is less obvious, which helps to improve the display effect of the display module 10.

[0056] In one embodiment of this application, both the first light-shielding structure C1 and the second light-shielding structure C2 include black pigment. The optical density value of the black pigment is related to the density of the black pigment. When the density of the black pigment increases, its optical density value increases; when the density of the black pigment decreases, its optical density value decreases.

[0057] If the density of the black pigment in the first light-blocking structure C1 is greater than the density of the black pigment in the second light-blocking structure C2, then the optical density value OD1 of the first light-blocking structure C1 is greater than the optical density value OD2 of the second light-blocking structure C2.

[0058] In this embodiment, adjusting the density of the black pigment to adjust the optical density value of the light-shielding structure helps to satisfy the condition OD1>OD2 and reduces the process difficulty of adjusting the optical density value of the light-shielding structure.

[0059] In one implementation, the density of the black pigment in the first light-shielding structure C1 is greater than the density of the black pigment in the second light-shielding structure C2, and the thickness of the first light-shielding structure C1 is equal to the thickness of the second light-shielding structure C2, so as to avoid the unevenness between the first light-shielding structure C1 and the second light-shielding structure C2 from causing manufacturing difficulties and display differences in the display module.

[0060] In one implementation, the density of the black pigment in the first light-shielding structure C1 is greater than that in the second light-shielding structure C2, and the thickness of the first light-shielding structure C1 is greater than that of the second light-shielding structure C2. This avoids the manufacturing difficulties and display differences caused by the unevenness between the first and second light-shielding structures C1 and C2. Achieving OD1 > OD2 through the difference in the density and thickness of the black pigment ensures the light-shielding effect of the second light-shielding structure C2 while reducing the manufacturing difficulties and display differences caused by the significant difference between the first and second light-shielding structures C1 and C2.

[0061] Figure 9 This is a schematic diagram of a partial structure of a display module provided in an embodiment of this application.

[0062] In one embodiment of this application, the second light-shielding structure C2 includes a plurality of first portions C21 and a plurality of second portions C22, wherein the first portions C21 and the second portions C22 are arranged alternately along a first direction X and a second direction Y, and the first direction X and the second direction Y intersect. For example, as Figure 9 As shown, the second light-shielding structure C2 includes multiple first parts C21 and multiple second parts C22. Along the direction perpendicular to the surface where the display module 10 is located, the orthographic projection of the first part C21 and the second part C22 can be distributed in a checkerboard pattern.

[0063] The optical density value of the first part C21 is different from the optical density value of the second part C22. For example, the optical density value of the first part C21 is greater than the optical density value of the second part C22. For example, the optical density value of the first part C21 is less than the optical density value of the second part C22.

[0064] In this embodiment, the optical density value of the first part C21 is different from that of the second part C22, thus the visibility of the first part C21 is different from that of the second part C22. This difference in visibility reduces the overall visibility of the second light-shielding structure C2, which helps to reduce the visual difference between the second light-shielding structure C2 and the first display area AA. Furthermore, it also maintains the light-shielding effect of the second light-shielding structure.

[0065] In one embodiment of this application, such as Figure 7 and Figure 8 As shown, the first display area AA includes multiple sub-pixels Pix, and a first light-shielding structure C1 is included between adjacent sub-pixels Pix. A second light-shielding structure C2 is disposed on the same layer as the first light-shielding structure C1.

[0066] The display module 10 includes a first film layer f1, and a first light-shielding structure C1 and a second light-shielding structure C2 are both located on the first film layer f1. Both the first light-shielding structure C1 and the second light-shielding structure C2 can be black matrices.

[0067] In one technical solution, combining Figure 7 and Figure 8 If a first light-shielding structure C1 is included between adjacent sub-pixels and the first border area B1 also includes a first light-shielding structure C1, then the second border area B2 includes a second light-shielding structure C2, which is set in the same layer as the first light-shielding structure C1 in the first display area AA and the first light-shielding structure in the first border area B1.

[0068] In this embodiment, the first light-shielding structure C1 and the second light-shielding structure C2 are disposed on the same film layer, which reduces the difficulty of fabricating the light-shielding structure.

[0069] At the same time, the incident light reaching the first light-shielding structure C1 and the incident light reaching the second light-shielding structure C2 pass through the same film layer in the display module 10, so that the loss caused by the two types of light passing through the film layer is consistent, and the difference in light intensity of the light incident on the first light-shielding structure C1 and the second light-shielding structure C2 is avoided from affecting the visibility of the first light-shielding structure C1 and the second light-shielding structure C2 respectively.

[0070] For example, if the intensity of the incident light reaching the first light-shielding structure C1 is α, and the intensity of the incident light reaching the second light-shielding structure C2 is β, then the light-shielding ability of the second light-shielding structure C2 is weaker than that of the first light-shielding structure C1 because the optical density value OD2 of the second light-shielding structure C2 is less than that of the first light-shielding structure C1. When the intensity of the incident light is the same, the intensity of the transmitted light through the first light-shielding structure C1 is less than that of the transmitted light through the second light-shielding structure C2. However, for the same light-shielding structure, the greater the intensity of the incident light, the greater the intensity of the transmitted light through the light-shielding structure. When α is much greater than β, the intensity of the transmitted light through the first light-shielding structure C1 may be greater than that through the second light-shielding structure C2, resulting in the visibility of the first light-shielding structure C1 being lower than that of the second light-shielding structure C2. Therefore, by placing the first light-shielding structure C1 and the second light-shielding structure C2 on the same film layer, the light intensity of the incident light reaching the first light-shielding structure C1 can be the same as the light intensity of the incident light reaching the second light-shielding structure C2, thus avoiding the occurrence of the above phenomenon.

[0071] Figure 10 This is a cross-sectional schematic diagram of a partial structure of a display module provided in an embodiment of this application.

[0072] In one embodiment of this application, such as Figure 10 As shown, the display module 10 includes a display panel DP and a cover plate P located on the light-emitting side of the display panel DP. The cover plate P can be used to protect the display panel DP and can improve the structural strength of the display module 10.

[0073] The first frame area B1 includes a first light-shielding structure C1 located between the display panel DP and the cover plate P, and a second light-shielding structure C2 is disposed on the same layer as the first light-shielding structure C1. For example, Figure 12 As shown, a second film layer f2 is included between the display panel DP and the cover plate P. The first light-shielding structure C1 and the second light-shielding structure C2 are both located in the second film layer f2. The first light-shielding structure C1 and the second light-shielding structure C2 can be ink.

[0074] In this embodiment, by placing both the first light-shielding structure C1 and the second light-shielding structure C2 on the second film layer f2, the fabrication difficulty of the light-shielding structure in the display module 10 is simplified. Simultaneously, the light-shielding structure can be fabricated by printing ink on the first film layer f1, which reduces the overall thickness of the display module 10.

[0075] When both the first light-shielding structure C1 and the second light-shielding structure C2 are made of ink, the optical density value of the light-shielding structure can be changed by adjusting the number of ink printing layers in the display module 10, which helps to achieve OD1 > OD2 and improve the display effect. When the number of printing layers increases, the optical density value of the light-shielding structure increases; when the number of printing layers decreases, the optical density value of the light-shielding structure decreases.

[0076] Figure 11 This is a cross-sectional schematic diagram of a partial structure of a display module provided in an embodiment of this application.

[0077] In one embodiment of this application, within the same second region A2, the second border region B2 includes at least two second light-shielding structures C2, for example, such as... Figure 11 As shown, the second border area B2 includes a primary second light-shielding structure C2m and a secondary second light-shielding structure C2n.

[0078] The first display area AA includes multiple sub-pixels Pix of different colors, and adjacent sub-pixels Pix are separated by a first light-blocking structure C1. For example, as Figure 11 As shown, the first display area AA includes a red pixel PR, a green pixel PG, and a blue pixel PB, which are alternately disposed in the first film layer f1. The main first light-shielding structure C1m is a first light-shielding structure C1 located in the first film layer f1. The main first light-shielding structure C1m separates adjacent sub-pixels Pix, and both the sub-pixels Pix and the main first light-shielding structure C1m are disposed in the first film layer f1.

[0079] The display module 10 includes a display panel DP and a cover plate P located on the light-emitting side of the display panel DP, such as Figure 11 As shown, the first frame area B1 includes a first light-shielding structure C1, which is located between the display panel DP and the cover plate P. The secondary first light-shielding structure C1n is the first light-shielding structure C1 disposed in the second film layer f2, and the secondary first light-shielding structure C1n is located in the first frame area B1. The second film layer f2 is located between the display panel DP and the cover plate P.

[0080] In at least two of the second light-shielding structures C2, one second light-shielding structure C2 is disposed on the same layer as the first light-shielding structure C1 located between adjacent sub-pixels Pix, and the other second light-shielding structure C2 is disposed on the same layer as the first light-shielding structure C1 located in the first border area B1. For example, as Figure 11 As shown, the primary second light-shielding structure C2m and the primary first light-shielding structure C1m are both disposed in the second film layer f2, and the secondary second light-shielding structure C2n and the secondary first light-shielding structure C1n are both disposed in the first film layer f1. The secondary second light-shielding structure C2n and the secondary first light-shielding structure C1n can both be ink, and the primary second light-shielding structure C2m and the primary first light-shielding structure C1m can both be black matrices.

[0081] In this embodiment, two second light-shielding structures C2 are disposed in different layers in the second border area B2. On the one hand, this enhances the blocking effect of the second light-shielding structures C2 on the traces in the second border area B2. On the other hand, the two second light-shielding structures C2 are disposed in the same layer as the main first light-shielding structure C1m and the secondary first light-shielding structure C1n, respectively, which reduces the manufacturing difficulty of the display module 10 and avoids the impact of different incident light intensities on the visibility of the first light-shielding structure C1 and the second light-shielding structure C2.

[0084] The visual contrast between the partial bezel area and the display area of ​​the display screen included in the embodiment of this application is reduced, thereby improving the user's visual experience.

[0085] The same or similar parts between the various embodiments in this specification can be referred to mutually. In particular, the device embodiments and terminal embodiments are basically similar to the method embodiments, so the description is relatively simple, and the relevant parts can be referred to the description in the method embodiments.
