In the representation of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0048] Figure 1 FIG. 1 shows a schematic diagram of a display module in the prior art. Figure 1As shown, the existing display module includes an OLED display panel 30', a support member 20' arranged on the non-light-emitting side of the display panel 30', and a metal support plate 10' arranged on the side of the support member 20' away from the OLED display panel 30'. Among them, the support member 20' includes a stacked PSA (Pressure Sensitive Adhesive) film layer 21', a BP (Back Plate) bottom film 23', a PSA film layer 21', a Foam / PI / PET layer 22' and a PSA film layer 21'. Among them, Foam is foam, PI is PI (Polyimide) is polyimide, and PET (Polyethylene terephthalate) is polyethylene terephthalate.

[0049] Figure 2 FIG. 1 shows a schematic diagram of the structure of a metal support plate in the prior art. Figure 2 As shown, the side of the metal support plate 10' close to the OLED display panel 30' is a smooth surface. When the incident light in the same direction irradiates the metal support plate 10', the reflected light is emitted from the smooth surface of the metal support plate 10' in the same direction. The incident light in this article is represented by a solid arrow, and the reflected light is represented by a dotted arrow. The incident light and the reflected light are also represented in the following text, and will not be explained later. The incident light in the same direction refers to the incident light with the same angle as the metal support plate 10', and the reflected light in the same direction refers to the reflected light with the same angle as the metal support plate 10'. Figure 2 The angle between the incident light and the metal support plate 10' is α. Currently, the design of the metal support plate 10 makes the incident light in the same direction be emitted in the same direction into the direction of the human eye after reflection, that is, the metal support plate 10' has a high reflectivity in the direction of the human eye, which affects the user's experience of viewing the display panel 30', resulting in poor display effect of the display panel.

[0050] Based on the above-mentioned problem that the reflectivity of the current metal support plate 10' is relatively high and affects the display effect of the display panel, an embodiment of the present invention provides a backplane structure for supporting the display panel, the backplane structure includes a metal support plate, the metal support plate includes a first surface, and the first surface has a scattering structure. The technical solution of the present invention is to set a scattering structure on the metal support plate, and the scattering structure scatters the light irradiated to the backplane structure out of the first surface in multiple different directions, thereby reducing the proportion of reflected light reflected in a specific direction. When the backplane structure is applied to the display module, the reflected light that originally enters the human eye in the same direction becomes only part of the reflected light entering the human eye, reducing the proportion of reflected light reflected in the direction of the human eye, improving the user's viewing experience of the display panel, and improving the display effect of the display panel.

[0051] The backplane structure provided by the present invention will be explained in detail below in conjunction with specific embodiments.

[0052] Figure 3 FIG. 1 is a schematic diagram showing a backplane structure provided by an embodiment of the present invention. Figure 3 As shown, the backplane structure includes a metal support plate 10, and the metal support plate 10 includes a first surface, and the first surface has a scattering structure, and the scattering structure is a boss 12. Specifically, the first surface includes a smooth surface 11 and a plurality of bosses 12 arranged at intervals on the smooth surface 11, wherein incident light in the same direction is incident on the boss 12 and then scattered out of the first surface in a plurality of different directions. Here, incident light in the same direction refers to incident light having the same angle with the first surface, Figure 3 The incident light in the same direction refers to the incident light with an angle α with the first surface. The boss 12 in the embodiment of the present invention is a spherical boss, but the shape of the boss 12 is not limited thereto, and may also be, for example, a cylindrical boss, a conical boss, etc. Those skilled in the art may set the specific shape of the boss 12 according to actual needs.

[0053] Please continue reading Figure 3 , when the incident light enters the first surface at an angle α with the first surface of the metal support plate 10, part of the incident light is irradiated onto the boss 12, and part of the incident light is irradiated onto the smooth surface 11. In this embodiment, since the boss 12 is a curved surface, the reflection direction of the reflected light is related to the tangent at the position point of the boss 12, wherein the angle between the normal perpendicular to the tangent and the incident light is the incident angle, and the angle between the normal perpendicular to the tangent and the reflected light is the reflection angle, and the incident angle and the reflection angle satisfy an equal relationship. Therefore, when the light enters the position point of the boss 12, due to the different tangents at different position points, the corresponding directions of the normals perpendicular to the tangents at the position points are also different, and thus the directions of the reflected light emitting from the first surface are also different, that is, the reflected light is scattered out of the first surface in multiple directions, rather than being reflected out of the first surface in a single direction. Furthermore, part of the incident light irradiated on the smooth surface 11 will be reflected by the smooth surface 11, and then will be incident on the boss 12 again, and will be scattered out of the first surface after multiple reflections. Similarly, the emission direction of the reflected light after multiple reflections will be emitted from multiple directions. Therefore, the setting of the boss 12 on the backplane structure makes the incident light in the same direction only reflect and then scatter out of the first surface in multiple directions, rather than being emitted in a single direction, that is, the proportion of reflected light in a specific direction will be reduced. When the backplane structure is applied to the display module, the proportion of reflected light entering the human eye will be reduced accordingly, that is, the amount of light entering the human eye will be reduced, thereby improving the user's viewing experience and improving the display effect of the display panel.

[0054] For further information, please refer to Figure 3 and Figure 4The distance d1 between two adjacent bosses 12 is 10 μm to 300 μm, and d1 can be 50 μm, 100 μm, 150 μm, 200 μm, or 250 μm. The width r1 of the boss 12 is 5 μm to 100 μm, and r1 can be 20 μm, 40 μm, 60 μm, or 80 μm. The height h1 of the boss 12 is less than 30 μm, and h1 can be 5 μm, 10 μm, 15 μm, 20 μm, or 25 μm.

[0055] Furthermore, if Figures 4 to 6 As shown, the bosses 12 are arranged in a curved or straight array on the smooth surface 11. Figure 4 As shown, the bosses 12 in the same row are arranged in a straight line in the first direction X, and the bosses 12 in the same column are arranged in a straight line in the second direction Y; Figure 5 The bosses 12 are shown arranged in a 5*9 matrix. Figure 5 As shown, the bosses 12 in the same row are arranged in a straight line in the first direction X, and the bosses 12 in adjacent rows are staggered, that is, the bosses 12 in the same column are not in a straight line in the second direction Y; Figure 5 The bosses 12 in adjacent rows are arranged in an S shape. Figure 6 As shown, the bosses 12 in the same row are arranged in a curve in the first direction X, and the bosses 12 in the same column are arranged in a straight line in the second direction Y. Reasonable design of the arrangement shape of the bosses 12 can reduce the crosstalk of light and improve the user's viewing experience when the backplane structure is applied to the display module. However, the arrangement of the bosses 12 is not limited to the above examples. For example, it can be designed as a circle, a parallelogram, etc. Those skilled in the art can set the arrangement pattern of the bosses 12 according to actual needs to achieve the best effect of reducing the proportion of reflected light in a specific direction.

[0056] about Figure 3 The preparation of the metal support plate 10 in the embodiment of the present invention can first provide a metal plate with a smooth surface, and then use a coating process to prepare the boss 12 on the smooth metal plate, thereby obtaining the metal support plate 10 with the boss 12. However, the preparation of the boss 12 is not limited thereto, and those skilled in the art can prepare the metal support plate 10 with the boss 12 according to actual needs.

[0057] like Figure 7 As shown, another embodiment of the present invention provides a backplane structure, the backplane structure includes a metal support plate 10, the metal support plate 10 includes a first surface, the first surface has a scattering structure, and the scattering structure is a groove 13. Specifically, as Figure 7 As shown, the first surface includes a smooth surface 11 and a plurality of grooves 13 arranged at intervals on the smooth surface 11, wherein incident light in the same direction is incident on the grooves 13 and then scattered out of the first surface in a plurality of different directions.

[0058] like Figure 7 As shown, the incident light in the same direction refers to the incident light with an angle of α with the first surface; when the incident light is incident on the first surface at an angle of α with the first surface of the metal support plate 10, part of the incident light is irradiated on the groove 13, and part of the incident light is irradiated on the smooth surface 11. In this embodiment, since the groove 13 is a curved surface, the reflection direction of the reflected light is related to the tangent at the position point of the groove 13, wherein the angle between the normal perpendicular to the tangent and the incident light is the incident angle, and the angle between the normal perpendicular to the tangent and the reflected light is the reflection angle, and the reflection angle and the incident angle satisfy an equal relationship. Therefore, when the light is incident on the position point of the groove 13, due to the different tangents at different positions, the corresponding directions of the normals perpendicular to the tangents at the position points are also different, and then the directions of the reflected light emitting from the first surface are also different, and the reflected light emits from the first surface in multiple directions. Furthermore, part of the incident light irradiated on the smooth surface 11 is emitted from the first surface in the same direction after reflection. Therefore, the arrangement of the grooves 13 on the back panel structure enables incident light in the same direction to be scattered out of the first surface in multiple directions rather than being emitted from the first surface in a single direction. Therefore, the incident light in the same direction is reflected by the back panel structure and then scattered out of the first surface in multiple different directions, which reduces the proportion of reflected light in a specific direction. When the back panel structure is applied to the display module, the proportion of reflected light at the display panel viewed by the human eye is correspondingly reduced, which reduces the light entering the human eye, thereby improving the display effect of the display panel and improving the user's viewing experience.

[0059] Furthermore, if Figure 7 As shown, the distance d2 between two adjacent grooves 13 is 10 μm to 300 μm, and d1 can be 50 μm, 100 μm, 150 μm, 200 μm, or 250 μm. The width r2 of the groove 13 is 5 μm to 100 μm, and r2 can be 20 μm, 40 μm, 60 μm, or 80 μm. The depth h2 of the groove 13 is less than 30 μm, and h2 can be 5 μm, 10 μm, 15 μm, 20 μm, or 25 μm.

[0060] Furthermore, if Figures 8 to 10 As shown, the grooves 13 are arranged in a curved or straight array on the smooth surface. Figure 8 As shown, the grooves 13 are arranged in a straight line along the first direction X and the second direction Y, the grooves 13 in adjacent rows are arranged in the same column, and the grooves 13 in adjacent columns are arranged in the same row. Fig.10 As shown, the grooves 13 in the same row are arranged in a straight line in the first direction X, and the grooves 13 in adjacent rows are staggered, that is, the grooves 13 in the same column are not in a straight line in the second direction Y. Fig.11 As shown, the grooves 13 in adjacent rows are arranged in an S shape. Fig.11As shown, the grooves 13 in the same row are arranged in a curved shape in the first direction X, and the grooves 13 in the same column are arranged in a straight line in the second direction Y. Reasonable design of the arrangement shape of the grooves 13 can reduce the crosstalk of light, so that the backplane structure is applied to the display module to improve the user's viewing experience. However, the arrangement of the grooves 13 is not limited to the above example, and those skilled in the art can set the arrangement pattern of the grooves 13 according to actual needs.

[0061] It should be noted that the shape of the groove 13 includes but is not limited to the circular groove mentioned above, and may also be a cylindrical groove, a trapezoidal groove, etc. Those skilled in the art may set the specific shape of the groove 13 according to actual needs.

[0062] Regarding the preparation of the metal support plate 10 with the groove 13, a metal plate with a smooth surface can be first provided, and then the groove 13 can be prepared on the smooth metal plate by laser or etching process, thereby obtaining the above-mentioned metal support plate 10 with the groove 13.

[0063] like Fig.11 As shown, another embodiment of the present invention provides a backplane structure, including a metal support plate 10, the metal support plate including a first surface, the first surface having a scattering structure, the scattering structure including a boss 12 and a groove 13. Specifically, the first surface includes a smooth surface 11 and bosses 12 and grooves 13 arranged at intervals on the smooth surface, wherein incident light in the same direction is incident on the grooves 13 and bosses 12, and then scattered out of the first surface in multiple different directions.

[0064] like Fig.11 As shown, the incident light in the same direction refers to the incident light with an angle α with the first surface, which is the same as the above description. Figure 3 and Figure 7 The setting principles of the middle boss 12 and the groove 13 are the same. Due to the setting of the boss 12 and the groove 13, the incident light in the same direction will be scattered out of the first surface of the metal support plate in multiple different directions after reflection. Compared with the metal support plate with a smooth surface in the prior art, the proportion of reflected light reflected in a specific direction will be reduced. When applied to the display module, the reflected light entering the human eye will be reduced, thereby improving the display effect of the display module and improving the user experience.

[0065] Furthermore, if Figure 12 to Figure 14 As shown, the bosses 12 and the grooves 13 are arranged in an array on the smooth surface 11 in a curved or straight line arrangement. Figure 5 As shown, the bosses 12 are arranged in a straight line along the first direction X and the second direction Y, the bosses 12 in adjacent rows are arranged in the same column, and the bosses 12 in adjacent columns are arranged in the same arrangement. Figure 6 As shown, the bosses 12 are arranged in a straight line in the first direction X, the bosses 12 are staggered in adjacent rows, and the bosses 12 are arranged in a Z-shaped pattern in the second direction Y. Figure 7 As shown, the bosses 12 are arranged in a curved shape in the first direction X. However, the arrangement of the bosses 12 is not limited to the above example, and those skilled in the art can set the arrangement pattern of the bosses 12 according to actual needs. The graphical design of the bosses 12 can reduce the light crosstalk phenomenon.

[0066] It should be noted that the spacing arrangement of the bosses 12 and the grooves 13 is not limited to the above example, for example, only the bosses 12 may be arranged on the same row, that is, the bosses 12 and the grooves 13 are arranged at intervals in the second direction Y. Those skilled in the art may set the specific spacing arrangement of the bosses 12 and the grooves 13 according to actual needs.

[0067] The specific preparation of the boss 12 and the groove 13 can refer to the preparation method of the metal support plate including only the boss 12 and the preparation method of the metal support plate including only the groove 13, which will not be repeated here. The spacing distance and size of the boss 12 and the groove 13 can refer to the setting of the boss 12 and the groove 13, which will not be repeated here.

[0068] In some preferred embodiments, the scattering structures are evenly distributed on the first surface. Figures 4 to 6 The bosses 12 are evenly distributed on the smooth surface 11, such as Figures 8 to 10 The grooves 13 are evenly distributed on the smooth surface 11, such as Figure 12 to Figure 14 The bosses 12 and grooves 13 shown are evenly distributed on the smooth surface 11. The evenly distributed scattering structure is conducive to the formation of regular reflection of reflected light, which satisfies the reduction of the reflection ratio of reflected light in a specific direction, thereby improving the reflectivity of light in a specific direction.

[0069] An embodiment of the present invention further provides a display module, comprising the backplane structure as described above and a display panel, wherein the backplane structure is located on one side of the display panel. Fig.15 FIG. 1 is a schematic diagram of a display module provided by an embodiment of the present invention. Fig.15 As shown, the display module includes a backplane structure and a display panel 30, wherein the backplane structure is located on one side of the display panel; wherein the backplane structure has a boss 12 on one side close to the display panel 30. In other embodiments, the backplane structure may be as follows: Figure 7 and Fig.11 The backplane structure shown, etc.

[0070] Furthermore, the backplane structure also includes a support layer 20 disposed between the metal support plate 10 and the display panel. The support layer 20 includes a PSA (Pressure Sensitive Adhesive) film layer 21, a BP (Black Plate) lower film 23, a PSA film layer 21, a Foam (foam) / PI (Polyimide) / PET (Polyethyleneterephthalate) layer 22, and a PSA film layer 21. The PSA film layer 21 has high adhesion, small curing shrinkage, strong water and high temperature resistance, and another good bonding gap filling property. Therefore, by connecting the film layers through the PSA film layer 21, the service life can be extended and the reliability of the display module can be enhanced. The Foam (foam) / PI (Polyimide) / PET (Polyethylene terephthalate) layer 22 has a buffering effect, providing support, buffering and heat dissipation for the display module. The BP bottom film 23 is used to reinforce the display panel to prevent the display panel from rolling up.

[0071] Correspondingly, the present application also provides a display device, which includes the display module as above. Fig.16 FIG. 2 shows a display device provided by an embodiment of the present invention. Fig.16 As shown, an embodiment of the present invention further provides a display device 100, which includes a display module as described above, so the display device 100 can obtain all the technical effects of the above-mentioned display module, which will not be repeated here. Specifically, the display device can be any device that displays images, whether moving (e.g., video) or fixed (e.g., still images), and whether text or images. More specifically, it is expected that the embodiments described can be implemented in or associated with a variety of electronic devices. The various electronic devices are, for example (but not limited to), mobile phones, wireless devices, personal data assistants (PDAs), handheld or portable computers, GPS receivers / navigators, cameras, MP4 video players, camcorders, game consoles, watches, clocks, calculators, TV monitors, flat panel displays, computer monitors, car displays, electronic photos, electronic billboards or signs, projectors, architectural structures, packaging and aesthetic structures, etc.

[0072] In summary, the backplane structure, display module and display device provided by the present invention have the following advantages:

[0073] The present invention sets a scattering structure on the first surface, so that incident light in the same direction can be emitted from multiple different directions after being reflected by the first surface, thereby reducing the proportion of reflected light reflected in a specific direction. When the backplane structure is applied to the display module, the incident light in the same direction irradiates the metal support plate and is reflected. The reflected light will also be scattered from the surface of the display module in multiple different directions and then enter the human eye. Since the reflected light will be scattered in multiple different directions, the proportion of the reflected light entering the viewing direction of the human eye will be reduced, thereby improving the experience of the human eye when viewing the screen and improving the display effect of the display panel.

[0074] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
