[0002] The embodiments of the present application relate to the field of display technology, and in particular to a watch face, a display module, and an electronic device. Background Art

[0003] Typically, electronic devices with display screens, such as televisions, large-size display screens, and all-in-one conference machines, require surface treatment to improve display quality and eliminate glare caused by ambient light reflected from the screen. However, eliminating glare reduces the contrast ratio of the ambient light. Summary of the Invention

[0005] In a first aspect, the present application provides a surface part, comprising a main body and a plurality of microstructure parts. The plurality of microstructure parts are arranged on the same side of the main body. The cross section of each microstructure part comprises a first region and a second region, and along the first direction, the length of the projection of the first region is greater than the length of the projection of the second region. Along the second direction, the height of the cross section of each microstructure part in the first direction first increases and then decreases. The cross section of the microstructure part is parallel to the first direction and the second direction, the vertex of the cross section of the microstructure part is located at the boundary line between the first region and the second region, the boundary line between the first region and the second region is perpendicular to the second direction, the first direction is perpendicular to the second direction, and the second direction is defined as the length direction of the microstructure part.

[0006] The surface member provided in the embodiments of the present application increases ambient light contrast by limiting the height of the microstructured portion's cross-section in a first direction to first increase and then decrease in a second direction, and by limiting the length of the projection of the first region in the cross-section to be greater than the projection of the second region. This allows the microstructured portion to increase the proportion of light reflected from the surface member onto the ground, thereby improving ambient light contrast. Furthermore, the multiple microstructured portions can redirect reflected light, thereby eliminating glare. Therefore, the surface member provided in the embodiments of the present application can simultaneously improve ambient light contrast while eliminating glare.

[0018] In a possible implementation manner, a cross section of at least one microstructure portion includes three first straight line segments connected end to end.

[0019] In one possible embodiment, the surface element satisfies the relationship: m / n>0.1 μm, where m refers to the sum of the heights of all microstructures of the surface element along the first direction, and n refers to the total number of microstructures of the surface element.

DETAILED DESCRIPTION

[0055] Typically, for electronic devices with display screens, such as televisions, large-size display screens, and all-in-one conference machines, in order to improve the display effect, the display screen needs to be surface treated to create an irregular, uneven surface structure. This can convert light reflected in one direction into scattered light reflected in all directions, thereby eliminating glare caused by ambient light reflected by the display screen. However, converting light reflected in one direction into scattered light reflected in all directions through the uneven, irregular surface structure eliminates glare while also reducing the ambient light contrast. This can cause the display screen to appear white, thereby reducing the display effect. Therefore, how to improve the ambient light contrast while eliminating glare has become a pressing issue.

[0056] In view of this, the present invention provides a surface member 200, a display module 100, and an electronic device that can eliminate glare while improving ambient light contrast. Ambient light contrast refers to the degree of contrast between light and dark on a display screen under a certain ambient light intensity.

[0057] FIG1 is a diagram showing an application scenario of a display module 100 provided in an embodiment of the present application. The embodiment of the present application provides an electronic device, which includes a display module 100. As shown in FIG1 , the display module 100 is used to display text, pictures, and other display information.

[0058] Among them, the electronic devices provided in the embodiments of the present application may include but are not limited to all-in-one conference machines, displays, televisions, electronic whiteboards, monitors, vehicles and other devices with display requirements.

[0059] It should be noted that the electronic device may include one or more display modules 100 , which is not limited here.

[0060] In the embodiment of the present application, there is no specific limitation on the specific structure of the display module 100. Several display modules 100 with different structures are described below.

[0061] Figure 2 is a cross-sectional view of a first display module 100 provided in an embodiment of the present application. In some possible implementations, as shown in Figure 2 , the display module 100 provided in an embodiment of the present application may include a surface member 200 and a light source member 300. The surface member 200 includes a main body 10 and a plurality of microstructure members 20, with the plurality of microstructure members 20 disposed on one side of the main body 10. The main body 10 is disposed between the light source member 300 and the microstructure members 20. The light source member 300 is configured to emit red, blue, and green light.

[0062] 2 , the light source component 300 includes a circuit board 310 and a plurality of light sources 320 . The plurality of light sources 320 are disposed on the same side of the circuit board 310 . Each light source 320 is configured to emit red light, blue light, and green light.

[0063] 2 , the light source 320 is disposed inside the surface member 200 . Therefore, functionally, the surface member 200 can also encapsulate multiple light sources 320 . In other words, the surface member 200 can be understood as being similar to an encapsulation member 400 .

[0064] Figure 3 is a cross-sectional view of a second display module 100 provided in an embodiment of the present application. In some possible implementations, as shown in Figure 3 , the display module 100 provided in an embodiment of the present application may include a surface member 200, an encapsulation member 400, and a light source member 300. The surface member 200 includes a main body 10 and a plurality of microstructure portions 20, and the encapsulation member 400 is disposed between the main body 10 and the light source member 300.

[0065] It should be noted that the two display modules 100 in Figures 2 and 3 represent two different direct display modules. Direct display is a technology that uses RGB three-color LED lights to directly display colors. Unlike backlight LED technology, it does not require backlight film materials for light mixing.

[0066] Figure 4 is a cross-sectional view of a third display module 100 provided in an embodiment of the present application. In some possible implementations, as shown in Figure 4 , the display module 100 provided in an embodiment of the present application may include a surface member 200 and a display panel 500. The surface member 200 is disposed on the display side of the display panel 500. The surface member 200 includes a main body 10 and a plurality of microstructure portions 20. The plurality of microstructure portions 20 are disposed on one side of the main body 10, and the main body 10 is disposed between the display panel 500 and the microstructure portions 20.

[0067] Among them, the display panel 500 provided in the embodiment of the present application may include but is not limited to an LED display panel, an LCD display panel, an OLED display panel, etc.

[0068] The following describes the implementation of the surface member 200 provided in the embodiment of the present application in conjunction with the accompanying drawings.

[0069] FIG5 is a cross-sectional view of a first surface member 200 provided in an embodiment of the present application. Referring to FIG5 , the surface member 200 in an embodiment of the present application includes a main body 10 and a plurality of microstructure portions 20. The plurality of microstructure portions 20 are disposed on the same side of the main body 10.

[0070] Fig. 6 is a schematic diagram of a first cross section of the microstructure portion 20 in Fig. 5. In an embodiment of the present application, referring to Fig. 6, the cross section of each microstructure portion 20 includes a first region 41 and a second region 42. Along a first direction (such as the Z direction in Fig. 5 or Fig. 6), the length of the projection of the first region 41 (shown in L1 in Fig. 6) is greater than the length of the projection of the second region 42 (shown in L2 in Fig. 6). Along a second direction (such as the Y direction in Fig. 5 or Fig. 6), the height of the cross section of each microstructure portion 20 in the first direction first increases and then decreases. Wherein, the cross section of the microstructure portion 20 is parallel to the first direction and the second direction, and the vertex of the cross section of the microstructure portion 20 (such as point B in Fig. 6) is located at the dividing line 30 between the first region 41 and the second region 42. The dividing line 30 between the first region 41 and the second region 42 is perpendicular to the second direction, and the first direction is perpendicular to the second direction, defining the second direction as the length direction of the microstructure portion 20.

[0071] It should be noted that in the embodiments of the present application, the first direction can be understood as the thickness direction of the microstructure portion 20, or the thickness direction of the surface member 200, or the direction perpendicular to the surface member 200. Alternatively, during use of the display module 100, the first direction can also be understood as the direction perpendicular to the display surface of the display module 100.

[0072] When the surface member 200 provided in the embodiment of the present application is in use, the thickness direction of the surface member 200 can be perpendicular to the vertical direction or intersect with the vertical direction and not overlap. Along the vertical direction, the first region 41 of the cross section of each microstructure portion 20 is located below the second region 42. In other words, the first region 41 of the cross section of each microstructure portion 20 is vertically oriented toward the bottom surface of the surface member 200, or in other words, point C in the cross section of each microstructure portion 20 is close to the ground. The vertical direction is parallel to the direction of gravity, and the ground refers to the floor of the space where the display module 100 is located.

[0073] FIG7 is a schematic diagram showing the principle of the microstructure portion 20 reflecting ambient light according to an embodiment of the present application. In FIG7 , (a) shows the relationship between incident light and reflected light when the reflective surface is parallel to the vertical direction, (b) shows the relationship between incident light and reflected light when the angle between the reflective surface and the vertical direction is a first angle, and (c) shows the relationship between incident light and reflected light when the angle between the reflective surface and the vertical direction is a second angle. As can be seen from FIG7 , when there is an angle between the reflective surface and the vertical direction, the angle between the reflected light and the vertical direction can be reduced, allowing more reflected light to be directed toward the ground.

[0074] Continuing with FIG6 , along the second direction (e.g., the Y direction in FIG6 ), the height of the cross-section of the microstructure portion 20 in the first direction (e.g., the Z direction in FIG6 ) first increases and then decreases, thereby dividing the surface of the microstructure portion 20 into two portions. When reflecting incident light, these two portions correspond to the combination of (b) and (c) in FIG7 . Furthermore, along the first direction (e.g., the Z direction in FIG5 or FIG6 ), the projected length of the first region 41 is greater than the projected length of the second region 42 , and the proximity of the first region 41 to the ground allows more reflected light to reach the ground, thereby increasing the proportion of ambient light reflected from the surface element 200 to the ground, thereby improving ambient light contrast.

[0075] In addition, in the embodiment of the present application, since the surface member 200 has multiple microstructure portions 20, the multiple microstructure portions 20 make the surface of the surface member 200 have an uneven surface structure, which can change the direction of reflected light and achieve the purpose of eliminating glare.

[0076] Therefore, by providing a microstructure portion 20 on the surface of the watch face 200 that satisfies the following restrictions: the height of the cross-section of the microstructure portion 20 in the first direction first increases and then decreases along the second direction, and the projection of the first region 41 along the first direction is greater than the length of the projection of the second region 42, the ambient light contrast can be improved while eliminating glare.

[0077] In some possible implementations, along the first direction, a ratio of a length of a projection of the first region 41 to a length of a projection of the second region 42 may be greater than or equal to 1.5.

[0078] 6 , the ratio of the length of the projection of the first region 41 to the length of the projection of the second region 42 is 2. Of course, the ratio of the length of the projection of the first region 41 to the length of the projection of the second region 42 may also be greater than or less than 2.

[0079] It should be noted that, along the first direction, the ratio of the length of the projection of the first area 41 to the length of the projection of the second area 42 may also be less than 1.5 and greater than 1, for example, including but not limited to 1.1, 1.2, 1.3, etc.

[0080] In summary, along the first direction, if the length of the projection of the first area 41 and the length of the projection of the second area 42 are greater than 1, the proportion of reflected light reflected to the ground can be increased, thereby achieving the purpose of improving the ambient light contrast. However, if the ratio of the length of the projection of the first area 41 to the length of the projection of the second area 42 is greater than or equal to 1.5, the proportion of reflected light reflected to the ground can be further increased.

[0081] In the embodiment of the present application, the cross-sectional shapes of the plurality of microstructure portions 20 of the surface part 200 may be the same, or the cross-sectional shapes of at least two microstructure portions 20 may be the same, or the cross-sectional shapes of each microstructure portion 20 may be different.

[0082] In the embodiment of the present application, there is no limitation on the shape of the cross section of the microstructure portion 20 .

[0083] Several cross sections of the microstructure portion 20 with different structures are described below.

[0084] In one possible embodiment, the cross section of at least one microstructure portion 20 includes a first straight line segment 51 and two first arc segments 52 with different curvatures. As shown in FIG6 , one end of the two first arc segments 52 intersects at the vertex of the cross section of the microstructure portion 20 , and the two ends of the first straight line segment 51 are respectively connected to the other ends of the two first arc segments 52 .

[0085] Continuing with FIG6 , the two first arc segments 52 have different curvatures. Furthermore, along the first direction (e.g., the Z direction in FIG6 ), the projections of the two first arc segments 52 differ in length. The projection of one first arc segment 52 in the first direction may be segment CD in FIG6 , while the projection of the other first arc segment 52 in the first direction may be segment AD in FIG6 . The length of the CD segment is greater than that of the AD segment. The lengths of the two first arc segments 52 are also different. Furthermore, the first region 41 is a BCD region, and the second region 42 is an ABD region.

[0086] In one possible embodiment, the cross section of at least one microstructure portion 20 includes a first arc segment 52 and two first straight segments 51. One end of the two first straight segments 51 is connected, one end of the first arc segment 52 is connected to the other end of each of the first straight segments 51, and the other end of the first arc segment 52 intersects with the other end of the other first straight segment 51 at the vertex of the cross section of the microstructure portion 20.

[0087] Since one of the two first straight line segments 51 intersects with the first arc segment 52 and the intersection point is the vertex of the cross section of the microstructure portion 20, and the other is the bottom edge of the cross section of the microstructure portion 20, the first straight line segment 51 intersecting with the first arc segment 52 at the vertex can belong to the first area 41 or the second area 42. Therefore, there is no restriction on the specific position of the first arc segment 52.

[0088] FIG8 is a schematic diagram of a second cross-section of a microstructure portion 20 provided in an embodiment of the present application. In some embodiments, referring to FIG8 , the first region 41 is formed by a first straight line segment 51 (shown as BC in FIG8 ) and a portion of another first straight line segment 51 (shown as CD in FIG8 ), and the second region 42 is formed by a first arc segment 52 (shown as AB in FIG8 ) and another portion of another first straight line segment 51 (shown as AD in FIG8 ).

[0089] FIG9 is a schematic diagram of a third cross-section of a microstructure portion 20 provided in an embodiment of the present application. In some embodiments, referring to FIG9 , the first region 41 is formed by a first arc segment 52 (shown as BC in FIG9 ) and a portion of a first straight line segment 51 (shown as CD in FIG9 ), and the second region 42 is formed by another first straight line segment 51 (shown as AB in FIG9 ) and another portion of a first straight line segment 51 (shown as AD in FIG9 ).

[0090] Figure 10 is a schematic diagram of a fourth cross-section of a microstructure portion 20 provided in an embodiment of the present application. In one possible embodiment, the cross-section of at least one microstructure portion 20 includes three first straight line segments 51 connected end to end. It is understood that the three first straight line segments 51 form a triangular cross-section of the microstructure portion 20.

[0091] It should be noted that when the cross section of the microstructure portion 20 is formed by a plurality of first straight line segments 51 , the number of the first straight line segments 51 may be more than three.

[0092] In summary, the embodiments of the present application illustrate four cross-sectional shapes of the microstructure portion 20 shown in FIG. 6 to FIG. 10 . However, the cross-sectional shape of the microstructure portion 20 is not limited to the four shapes shown in FIG. 6 to FIG. 10 , and may also be other shapes.

[0093] In the embodiment of the present application, there is no limitation on the specific shape of the arc segment 52 in Figures 6 to 9. For example, the first arc segment 52 in Figures 6 to 9 may satisfy the ellipse equation, for example, in Figure 6:

[0094] Segment AB can satisfy the ellipse equation The BC segment can satisfy the ellipse equation

[0095] Here, x refers to the horizontal coordinate of a point on the first arc segment 52 in the second direction (such as the Y direction in Figure 6), and y refers to the vertical coordinate of a point on the first arc segment 52 in the first direction (such as the Z direction in Figure 6).

[0096] In the embodiment of the present application, there is no limitation on the shape of the longitudinal cross-section of the microstructure portion 20. The longitudinal cross-section of the microstructure portion 20 is perpendicular to the cross-section of the microstructure portion 20 and parallel to the first direction, and the first direction, the second direction, and the third direction (e.g., the X direction in FIG. 11B ) are mutually perpendicular.

[0097] In the embodiment of the present application, there are multiple microstructure parts 20, and the shapes of the longitudinal sections of the multiple microstructure parts 20 may be different, or the shapes of the longitudinal sections of the multiple microstructure parts 20 may be all the same or partially the same.

[0098] Several longitudinal cross-sectional shapes of the microstructure portion 20 are described below.

[0099] Figure 11A is a schematic top view of the second microstructure portion provided in an embodiment of the present application, and Figure 11B is a schematic diagram of a first longitudinal section of the microstructure portion in Figure 11A , wherein Figure 11B is a schematic diagram of a longitudinal section taken at AA in Figure 11A .

[0100] In some possible implementations, along the third direction (eg, X direction in FIG. 11B ), the height of the longitudinal section of at least one microstructure portion 20 first increases and then decreases, as shown in FIG. 11B .

[0101] Continuing with FIG11B , the longitudinal cross-section of the microstructure portion 20 includes a second straight segment 53 and a second arc segment 54, with the ends of the second arc segment 54 respectively connected to the ends of the second straight segment 53. The specific shape of the second arc segment 54 is not limited herein. For example, as shown in FIG11B , the second arc segment 54 is semicircular.

[0102] It should be noted that the shape of the longitudinal cross-section of the microstructure portion 20 that satisfies the requirement that the height first increases and then decreases is not limited to that shown in FIG11B and may also be other shapes. For example, referring to FIG12 , the longitudinal cross-section of the microstructure portion 20 includes three second straight line segments 53 connected end to end, and the longitudinal cross-section of the microstructure portion 20 is similar to a triangle. FIG12 is a schematic diagram of a second longitudinal cross-section of the microstructure portion 20 provided in an embodiment of the present application.

[0103] Alternatively, in some embodiments, the longitudinal section of the microstructure portion 20 may also include a second arc segment 54 and two second straight line segments 53, one of the two second straight line segments 53 being the bottom edge of the longitudinal section of the microstructure portion 20, and the other being a side edge of the longitudinal section of the microstructure portion 20, and the second arc segment 54 being the other side edge of the microstructure portion 20, so that the shape of the longitudinal section of the microstructure portion 20 is similar to the shape in Figures 8 and 9.

[0104] In some possible implementations, along the third direction, the height of the longitudinal section of at least one microstructure portion 20 gradually increases or decreases (not shown in the figures). For example, the shape of the longitudinal section of the microstructure portion 20 that satisfies the gradual decrease or increase in height can be half of that in FIG. 11B or FIG. 12 , with the dotted line in FIG. 11B or FIG. 12 as the dividing line 30. In other words, in some embodiments, the longitudinal section of the microstructure portion 20 can include two second straight line segments 53 and one second arc segment 54, with one end of the two second straight line segments 53 connected, and the other ends of the two second straight line segments 53 respectively connected to the two ends of the second arc segment 54.

[0105] In some possible implementations, along the third direction, the longitudinal cross-section of at least one microstructure portion 20 is arranged at the same height, as shown in Figure 13. Figure 13 is a schematic diagram of a third longitudinal cross-section of the microstructure portion 20 provided in an embodiment of the present application.

[0106] Continuing to refer to FIG. 13 , the longitudinal section of the microstructure portion 20 includes four second straight line segments 53 connected end to end, so that the longitudinal section of the microstructure portion 20 is rectangular.

[0107] In summary, the shape of the longitudinal section of the microstructure portion 20 may be other shapes besides the shapes described above.

[0108] In the embodiment of the present application, the structures of the plurality of microstructure portions 20 of the surface member 200 may be the same, or may be partially the same, or may be completely different. In addition, in the embodiment of the present application, the structure of the microstructure portion 20 is not limited here.

[0109] Several microstructure portions 20 with different structures are described below.

[0110] Figure 14 is a top view of the first microstructure portion in Figure 5. In some possible implementations, as shown in Figure 14, at least one microstructure portion 20 includes a first portion 21 and a second portion 22, and the first portion 21 and the second portion 22 are mirror-symmetrical about an axis of symmetry parallel to the second direction.

[0111] Continuing with FIG14 , the first portion 21 and the second portion 22 are an integral structure. However, the first portion 21 and the second portion 22 may also be separate structures. For example, referring to FIG15 , the first portion 21 and the second portion 22 are spaced apart along a third direction (e.g., the X direction in FIG15 ). FIG15 is a top view of the third microstructure portion provided in an embodiment of the present application.

[0112] Figure 16 is a top view of a fourth microstructure portion provided in an embodiment of the present application. In some possible implementations, at least one microstructure portion 20 includes a first portion 21 and a second portion 22, and along the first direction, the length of the projection of the first portion 21 in the third direction is different from the length of the projection of the second portion 22 in the third direction.

[0113] For example, as shown in FIG16 , along the first direction, the length of the projection of the first portion 21 in the third direction is greater than the length of the projection of the second portion 22 in the third direction. Alternatively, in some embodiments, along the first direction, the length of the projection of the first portion 21 in the third direction may also be less than the length of the projection of the second portion 22 in the third direction (not shown in the figure).

[0114] Of course, the microstructure portion 20 may also have other structures besides being composed of the first portion 21 and the second portion 22. In some embodiments, the microstructure portion 20 may also be composed of one of the first portion 21 and the second portion 22. For example, as shown in FIG17 , the microstructure portion 20 is composed of the first portion 21. FIG17 is a top view of the fifth microstructure portion provided in an embodiment of the present application.

[0115] In summary, the structure of the microstructure portion 20 may be other structures besides the above structures.

[0116] In some possible implementations, along the first direction, the width of the projection of at least one microstructure portion 20 in the third direction first increases and then decreases, as shown in Figure 14. This configuration makes the microstructure portion 20 similar to a water droplet structure, which can further increase the proportion of reflected light reflected to the ground.

[0117] Since the surface part 200 has multiple microstructure portions 20, the number of microstructure portions 20 that satisfy the requirement that the width of the projection in the third direction first increases and then decreases can be at least a part of the multiple ones, or in some embodiments, the width of the projection in the third direction of each microstructure portion 20 in the surface part 200 first increases and then decreases.

[0118] In the embodiment of the present application, the surface member 200 includes a plurality of microstructure portions 20. There is no limitation on the width of the plurality of microstructure portions 20. The width of the microstructure portion 20 refers to the maximum width of the microstructure portion 20 in the third direction (e.g., as shown by K in FIG. 14 ).

[0119] In some possible implementations, along the third direction, the widths of at least two microstructure portions 20 may be different. For example, the surface part 200 includes ten microstructure portions 20, five of which have different widths, and the remaining microstructure portions 20 have the same width. Of course, the number of microstructure portions 20 with different widths may be more or less than five.

[0120] The widths of the plurality of microstructure portions 20 in the surface element 200 may all be different, or some may be different and others the same. In other words, the surface element 200 may include at least two types of microstructure portions 20 with different widths.

[0121] Of course, in some possible implementations, the widths of the multiple microstructure portions 20 of the surface member 200 may also be the same. For example, the surface member 200 includes ten microstructure portions 20 , and the widths of the ten microstructure portions 20 are all the same.

[0122] In the embodiment of the present application, the surface member 200 includes a plurality of microstructure portions 20. There is no limitation on the length of the plurality of microstructure portions 20. The length of the microstructure portion 20 refers to the maximum length of the microstructure portion 20 in the second direction (e.g., as shown by L3 in FIG. 14 ).

[0123] In some possible implementations, along the second direction, the lengths of at least two microstructure portions 20 may be different. For example, the surface part 200 includes ten microstructure portions 20, five of which have different lengths, and the remaining microstructure portions 20 have the same length. Of course, the number of microstructure portions 20 with different lengths may be more or less than five.

[0124] The lengths of the plurality of microstructure portions 20 in the surface element 200 may all be different, or some may be different and others the same. In other words, the surface element 200 may include at least two types of microstructure portions 20 with different lengths.

[0125] Of course, in some possible implementations, the lengths of the multiple microstructure portions 20 of the surface member 200 may also be the same. For example, the surface member 200 includes ten microstructure portions 20 , and the lengths of the ten microstructure portions 20 are all the same.

[0126] In the embodiment of the present application, the surface member 200 includes a plurality of microstructure portions 20. There is no limitation on the height of the microstructure portions 20. The height of the microstructure portion 20 refers to the maximum height of the microstructure portion 20 in the first direction (e.g., as shown by H1 in FIG6 ).

[0127] Figure 18 is a cross-sectional view of a second surface member 200 provided in an embodiment of the present application. In some possible implementations, along the first direction, at least two microstructured portions 20 may have different heights. For example, as shown in Figure 18 , surface member 200 includes seven microstructured portions 20, two of which have different heights from the other five microstructured portions 20, and two of which have the same height as the other five microstructured portions 20.

[0128] The heights of the plurality of microstructures 20 in the surface element 200 may all be different, or some may be different and others the same. In other words, the surface element 200 may include at least two types of microstructures 20 with different heights.

[0129] Of course, in some possible implementations, along the first direction, the heights of the plurality of microstructure portions 20 of the surface member 200 may also be the same. For example, the surface member 200 includes ten microstructure portions 20 , and the heights of the ten microstructure portions 20 are all the same.

[0130] In one possible embodiment, the surface element 200 can satisfy the relationship: m / n>0.1 μm, where m refers to the sum of the heights of all microstructures 20 of the surface element 200 along the first direction, and n refers to the total number of microstructures 20 in the surface element 200. The length of each microstructure 20 along the second direction is greater than or equal to 780 nm, and the width of each microstructure 20 along the third direction is greater than or equal to 780 nm. This configuration allows the microstructures 20 to reflect ambient light in multiple directions, thereby eliminating glare.

[0131] In a possible embodiment, the height of each microstructure portion 20 in the first direction (as shown by H1 in FIG6 ) may be greater than or equal to 0.1 μm, which can ensure that each microstructure portion 20 reflects visible light in ambient light to eliminate glare.

[0132] Alternatively, in a possible embodiment, the height of each microstructure portion 20 in the first direction may be less than or equal to 10 μm, which can prevent the microstructure portion 20 from being too high along the first direction, so that the surface roughness of the surface member 200 meets the requirements.

[0133] Since the surface member 200 has a plurality of microstructure portions 20 , the heights of the plurality of microstructure portions 20 may be at least partially the same or different, which is not limited here.

[0134] In the embodiment of the present application, there is no limitation on the arrangement of the plurality of microstructure portions 20 of the surface member 200 .

[0135] Several arrangements of the plurality of microstructure portions 20 in the surface element 200 are described below.

[0136] Figure 19 is a schematic diagram illustrating a first arrangement of the multiple microstructures 20 of the dial 200 in Figure 5 . In some possible implementations, as shown in Figure 19 , the multiple microstructures 20 of the dial 200 are arranged in a two-dimensional array along the second and third directions. In other words, the dial 200 includes multiple structural groups, each of which is arranged side by side along the second direction. Each structural group includes multiple microstructures 20 arranged side by side along the third direction. This arrangement ensures an orderly arrangement of the multiple microstructures 20, reducing the manufacturing complexity of the dial 200.

[0137] Figure 20 is a schematic diagram illustrating a second arrangement of multiple microstructures 20 of a surface member 200 according to an embodiment of the present application. In some possible implementations, as shown in Figure 20 , multiple structure groups of surface member 200 are arranged side by side along the second direction. Along the third direction, each structure group includes multiple microstructures 20 arranged side by side, and the microstructures 20 of two adjacent structure groups are staggered.

[0138] Among them, the staggered arrangement can be understood as any microstructure portion 20 of one structural group in two adjacent structural groups being arranged between two adjacent microstructure portions 20 in the other structural group, or it can also be understood as along the second direction, the projection of any microstructure portion 20 in one structural group partially overlaps with the projection of one structural portion in the other structural group or overlaps with the projection of two adjacent microstructure portions 20 in the other structural group.

[0139] It should be noted that when the plurality of microstructure portions 20 in the surface member 200 are arranged in a disordered manner, the problems of rainbow patterns and moiré patterns can be avoided, which helps to improve the display effect.

[0140] As can be seen from Figures 19 and 20 , the multiple microstructures 20 in the watch face 200 are arranged in an orderly fashion. However, this arrangement is not necessary. Figure 21 illustrates a third arrangement of the multiple microstructures 20 in the watch face 200 according to an embodiment of the present application. For example, as shown in Figure 21 , the multiple microstructures 20 in the watch face 200 are arranged in a disordered fashion. It is understood that a disordered arrangement can be understood as a lack of regularity in the arrangement of the multiple microstructures 20.

[0141] In summary, in addition to being arranged in an orderly manner or not arranged at all, the multiple microstructure parts 20 in the surface part 200 can also be arranged in other ways. For example, in some embodiments, the surface part 200 includes multiple arrangement groups, and the multiple arrangement groups are arranged in an disorderly manner. Each arrangement group includes multiple microstructure parts 20 arranged in an orderly manner (as shown in the figure).

[0142] In some embodiments, when the multiple microstructure portions 20 in the surface part 200 are arranged in an orderly manner, the widths of the multiple microstructure portions 20 in the surface part 200 can be the same (for example, as shown in Figure 19 or Figure 20). Of course, the widths of the multiple microstructure portions 20 in the surface part 200 can also be partially the same (not shown in the figure), or can also be completely different (not shown in the figure).

[0143] In some embodiments, when the multiple microstructure portions 20 in the surface part 200 are arranged in an orderly manner, the lengths of the multiple microstructure portions 20 in the surface part 200 can be the same (for example, as shown in Figure 19 or Figure 20). Of course, the lengths of the multiple microstructure portions 20 in the surface part 200 can also be partially the same (not shown in the figure), or can also be completely different (not shown in the figure).

[0144] In some embodiments, when the multiple microstructure portions 20 in the surface part 200 are arranged in an orderly manner, the heights of the multiple microstructure portions 20 in the surface part 200 can be the same (for example, as shown in Figure 5). Of course, the heights of the multiple microstructure portions 20 in the surface part 200 can also be partially the same (not shown in the figure), or can also be completely different (not shown in the figure).

[0145] In some embodiments, when the multiple microstructure portions 20 in the surface part 200 are arranged in a disorderly manner, the heights of the multiple microstructure portions 20 in the surface part 200 can be partially the same (for example, as shown in Figure 18). Of course, the heights of the multiple microstructure portions 20 in the surface part 200 can also be all the same (not shown in the figure), or they can also be all different (not shown in the figure).

[0146] In some embodiments, when the multiple microstructure portions 20 in the surface part 200 are arranged in a disordered manner, the widths of the multiple microstructure portions 20 in the surface part 200 can be partially the same (for example, as shown in Figure 21). Of course, the widths of the multiple microstructure portions 20 in the surface part 200 can also be all the same (not shown in the figure), or they can also be all different (not shown in the figure).

[0147] In some embodiments, when the multiple microstructure portions 20 in the surface part 200 are arranged in a disordered manner, the lengths of the multiple microstructure portions 20 in the surface part 200 can be partially the same (for example, as shown in Figure 21). Of course, the lengths of the multiple microstructure portions 20 in the surface part 200 can also be all the same (not shown in the figure), or they can also be all different (not shown in the figure).

[0148] It should be noted that when the plurality of microstructure portions 20 in the surface member 200 are arranged in an orderly or disorderly manner, in addition to the microstructure portion shown in FIG14 , microstructure portions 20 of other structures may also be used for orderly or disorderly arrangement, such as those shown in FIG22 to FIG27 . FIG22 is a schematic diagram of the arrangement of the fifth type of microstructure portion provided in an embodiment of the present application, FIG23 is a schematic diagram of the arrangement of the sixth type of microstructure portion provided in an embodiment of the present application, FIG24 is a schematic diagram of the arrangement of the seventh type of microstructure portion provided in an embodiment of the present application, FIG25 is a schematic diagram of the arrangement of the eighth type of microstructure portion provided in an embodiment of the present application, FIG26 is a schematic diagram of the arrangement of the ninth type of microstructure portion provided in an embodiment of the present application, and FIG27 is a schematic diagram of the arrangement of the eleventh type of microstructure portion provided in an embodiment of the present application.

[0149] As can be seen from Figures 19 to 21 , the multiple microstructures 20 in the dial 200 have the same structure (e.g., the microstructure 20 shown in Figure 14 ). In other words, the dial 200 includes microstructures 20 of one structure. Of course, in some embodiments, the dial 200 may also include at least two microstructures 20 with different structures.

[0150] Figure 28 is a schematic diagram of the arrangement of the twelfth type of microstructure provided in an embodiment of the present application. For example, the surface member 200 includes two microstructures 20 with different structures, which are arranged in an orderly manner. Of course, the two microstructures 20 with different structures can also be arranged in an orderly and staggered manner or in a disordered manner.

[0151] It should be noted that the microstructure portion near the edge of the surface part may be other structures in addition to the microstructure portion shown in Figure 14. For example, in some embodiments, referring to Figure 28, the microstructure portion near the edge of the surface part may be the microstructure portion shown in Figure 17. When multiple display modules are spliced ​​together, two microstructure portions belonging to two adjacent display modules can be spliced ​​into the microstructure portion shown in Figure 15.

[0152] In the description of the embodiments of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to a fixed connection, an indirect connection via an intermediate medium, internal communication between two components, or an interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of this application based on specific circumstances.

[0153] The terms "first", "second", "third", "fourth", etc. (if any) in the description and claims of the embodiments of this application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.
