[0054] In the following, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature and not restrictive.

[0055] Figure 1 The structural schematic diagram of the display module in the related art is shown. Refer to Figure 1 , in the related art, the display module 1' includes a backlight module 10' and a display panel 20'. The backlight module 10' includes a backplane 11' and a rubber frame 12'. The rubber frame 12' is arranged inside the backplane 11'. The display panel 20' is arranged inside the rubber frame 12' and supported on the rubber frame 12'. The light-shielding tape 30' is wrapped around the backplane 11', the rubber frame 12' and the display panel 20' to achieve the fixation between the backplane 11', the rubber frame 12' and the display panel 20'. For the display module 1' arranged in this way, the size of the display panel 20' is smaller than that of the backlight module 10'. It is difficult to achieve a full-screen and narrow bezel in this way.

[0056] Figure 2 The top view of the display module according to the embodiment of the present application is shown. Figure 3 Shown Figure 2 The cross-sectional view taken along A-A in Figure 2 and Figure 3 , the present application provides a display module 1, which includes: a backlight module 10, a display panel 30 and a light-shielding layer 40. The display module 1 provided by the embodiment of the present application can achieve a full-screen and narrow bezel.

[0057] Refer to Figure 2 and Figure 3 , the backlight module 10 is used to provide backlight for the display module 1. The backlight module 10 includes a backplane 100. The backplane 100 includes a main body 110 and a first side plate 120. The main body 110 and the first side plate 120 cooperate to enclose a receiving space. A backlight source (not shown in the figure) is arranged in the receiving space, and the backlight source is configured to provide light.

[0058] Refer to Figure 2 and Figure 3, the display panel 30 is connected to the first side plate 120 through the first bonding portion 20. Thus, the setting of the first bonding portion 20 can achieve the fixation between the display panel 30 and the first side plate 120, and the display panel 30 is disposed outside the accommodation space. The display panel 30 includes a first end face 31 close to the main body 110, a second end face 32 away from the main body 110, and a first side face 33 respectively connected to the first end face 31 and the second end face 32. The display panel 30 has a display area 392 and a non-display area 391 surrounding the outer periphery of the display area 392. The orthographic projection of the first side plate 120 on the display panel 30 is located within the display area 392. That is, the size of the display area 392 of the display panel 30 is larger than the size of the backlight module 10, so that the display area 392 of the display panel 30 can cover the backlight module 10.

[0059] It can be understood that a light guide plate 180 is disposed in the accommodation space. When the light emitted by the backlight source disposed around the light guide plate 180 enters the light guide plate 180, the light guide plate 180 can change the propagation direction of these lights, so that these lights are all emitted from the light guide plate 180 to provide backlight for the display panel 30.

[0060] Figure 5 Show Figure 3 The enlarged schematic diagram of A in (showing the structural schematic diagram of the display panel in an embodiment), see Figure 5 , the light-shielding layer 40 covers the first side face 33, the first end face 31, and the second end face 32, and the orthographic projection of the light-shielding layer 40 on the display panel 30 is located within the non-display area 391.

[0061] According to the display module 1 provided by the embodiments of the present application, the display panel 30 of the present application is connected to the first side plate 120 through the first bonding portion 20, thereby realizing the fixation between the display panel 30 and the backlight module 10. Secondly, the present application arranges the display panel 30 outside the accommodation space, thereby canceling the dimensional limitations of the first side plate 120 and the back plate 100 on the display panel 30, making the area of the display panel 30 of the present application larger than the area of the backlight module 10 during design. When the user views the display module 1, the backlight module 10 is located on the side of the display panel 30 facing away from the user, and the user can only see the existence of the display panel 30, thereby realizing the full-screen effect of the display module 1. Furthermore, the orthographic projection of the first side plate 120 of the present application on the display panel 30 is located within the display area 392, making the size of the display panel 30 of the present application larger than the size of the backlight module 10. At the same time, the present application sets a light-shielding layer 40 on the first side surface 33, the first end surface 31, and the second end surface 32 at the edge of the display panel 30 to block the light at the edge position of the display panel 30, preventing the light emitted by the backlight module 10 from leaking from the edge of the display panel 30, thereby improving the problem of the periphery of the display panel 30 emitting light. Further, the present application directly uses the display panel 30 as the glass cover plate of the present application, and only through a relatively small range of the light-shielding layer 40 can the light shielding of the edge of the display panel 30 be realized, which can effectively realize the full-screen effect of the display module 1 without causing light leakage of the display panel 30. Further, the backlight module 10 of the present application occupies a relatively small range of the display panel 30, thereby realizing the narrow-border effect of the display module 1.

[0062] In some embodiments, the light-shielding layer 40 can be made of a black material. The black material has a light-absorbing effect, and the light-shielding layer 40 can absorb the light leaking from the first side surface 33, the first end surface 31, and the second end surface 32 at the edge of the display panel 30, thereby further reducing the problem of light leakage at the edge of the display panel 30.

[0063] Exemplarily, the light-shielding layer 40 of the present application is made of black ink. The black ink is printed on the edge of the display panel 30. The black edge formed by the black ink can absorb the light leaking at the edge of the display panel 30. The material of the black ink can be materials such as epoxy and polymethyl acrylate, which are not limited herein.

[0064] In some embodiments, the first side plate 120 includes a first vertically bent section 121. One end of the first vertically bent section 121 is connected to one side edge of the body 110, and the display panel 30 is connected to the other end of the first vertically bent section 121 through the first bonding portion 20. The extending direction of the first vertically bent section 121 intersects with the body 110. Specifically, the extending direction of the first vertically bent section 121 is perpendicular to the body 110, and the body 110 and the first vertically bent section 121 enclose an accommodation space.

[0065] In some embodiments, referring to Figure 2 and Figure 3 , the first side plate 120 further includes a first transverse bending section 122. The first transverse bending section 122 is connected to the other end of the first vertical bending section 121 away from the body 110. The first transverse bending section 122 extends in a direction away from the center of the backlight module 10. At least a part of the orthographic projection of the first transverse bending section 122 on the display panel 30 is located within the display area 392. The first bonding portion 20 at least partially extends to the side of the first transverse bending section 122 facing the display panel 30. The first transverse bending section 122 is bonded to the first end face 31 through the first bonding portion 20, so that the first transverse bending section 122 is bonded to the first end face 31 through the first bonding portion 20, thereby realizing the connection between the first transverse bending section 122 and the display panel 30.

[0066] Specifically, the first transverse bending section 122 is parallel to the body 110, and the first transverse bending section 122 is parallel to the first end face 31. With such a setting, the distance between the first end face 31 and the first transverse bending section 122 can be made equal everywhere, so that the connection stability between the first end face 31 and the first transverse bending section 122 is higher.

[0067] In the embodiments of the present application, in order to improve the connection strength between the display panel 30 and the first transverse bending section 122, the first bonding portion 20 covers the first end face 31, thereby increasing the connection area between the first transverse bending section 122 and the first end face 31 of the display panel 30, and thus improving the connection strength between the display panel 30 and the first transverse bending section 122.

[0068] Exemplarily, the orthographic projection of the first transverse bending section 122 on the display panel 30 is located within the display area 392. In some other embodiments, a part of the orthographic projection of the first transverse bending section 122 on the display panel 30 is located within the display area 392, and another part is located within the non-display area 391.

[0069] Figure 4 Shows Figure 2 the cross-sectional view taken along B-B in, in the embodiments of the present application, referring to Figure 2 and Figure 4, a terminal area is provided on the lower side of the display module 1. Therefore, it is necessary to reserve a certain area corresponding to the terminal area on the lower side of the display panel 30 to set components such as bare chips, rigid circuit boards, and flexible circuit boards. Since the edge of the display panel 30 in the above embodiment is not supported by the backlight module 10, that is, the edge of the display panel 30 in the above embodiment is in a suspended state. If a terminal area is set at the suspended position of the display panel 30 and too many electronic components are set in the terminal area, it is easy to cause breakage at this position. Therefore, the first side plate 120 of the present application is applied to at least one of the upper side, left side, and right side of the display module 1. Exemplarily, the first side plate 120 and the light-shielding layer 40 in the above embodiment are applied to the left side and the right side. In some other embodiments, the first side plate 120 and the light-shielding layer 40 in the above embodiment are applied to the left side or the right side. In some other embodiments, the first side plate 120 and the light-shielding layer 40 in the above embodiment are simultaneously applied to the left side, the right side, or the upper side. It can be understood that the present application does not specifically limit the setting positions of the first side plate 120 and the light-shielding layer 40 in the above embodiment on the upper side, left side, and right side of the display module 1.

[0070] In some embodiments, the first bonding portion 20 is an adhesive fixing tape, and the adhesive fixing tape bonds the first end face 31 and the first lateral bending section 122 respectively.

[0071] In some embodiments, to solve the problem that setting a terminal area at the suspended position of the display panel 30 and setting too many electronic components in the terminal area are likely to cause breakage at this position, refer to Figure 2 and Figure 4, the display panel 30 of the present application further includes a second side surface 34, and the backplane 100 further includes a second side plate 130. The second side plate 130 includes a second vertical bending section 131 and a second horizontal bending section 132. The second side surface 34 is respectively connected to the first end surface 31 and the second end surface 32. The second vertical bending section 131 is connected to one side edge of the main body 110. The second horizontal bending section 132 is disposed at one end of the second vertical bending section 131 away from the main body 110. The second horizontal bending section 132 extends in a direction towards the center of the backlight module 10. The orthographic projection of the second side surface 34 on the main body 110 is located within the orthographic projection of the second horizontal bending section 132 on the main body 110, so that the second side surface 34 on the lower side of the display panel 30 is located within the range of the backlight module 10. That is, the terminal area on the display panel 30 under the display module 1 falls within the range of the display module 1. With such a setting, the position on the display panel 30 corresponding to the terminal area is supported on the second horizontal bending section 132, avoiding the situation that the position on the display panel 30 corresponding to the terminal area is broken due to suspension. The second horizontal bending section 132 is bonded to the display panel 30 through a second bonding portion 90, so that the second horizontal bending section 132 is bonded to the first end surface 31 through the second bonding portion 90, thereby realizing the connection between the second horizontal bending section 132 and the display panel 30.

[0072] Specifically, the extending direction of the second vertical bending section 131 is perpendicular to the main body 110. The main body 110, the first vertical bending section 121, and the second vertical bending section 131 enclose a receiving space. Exemplarily, there are three first vertical bending sections 121, and the three first vertical bending sections 121 are respectively disposed on the left side, the upper side, and the right side edges of the main body 110. The second vertical bending section 131 is disposed on the lower side edge of the main body 110. The three first vertical bending sections 121 and the second vertical bending section 131 enclose a square frame.

[0073] Specifically, the second horizontal bending section 132 is parallel to the main body 110, and the second horizontal bending section 132 is parallel to the first end surface 31. With such a setting, the distance between the first end surface 31 and the second horizontal bending section 132 can be made equal everywhere, thereby making the connection stability between the first end surface 31 and the second horizontal bending section 132 higher.

[0074] In some embodiments, the second bonding portion 90 is a sticky fixing tape, and the sticky fixing tape bonds the first end surface 31 and the second horizontal bending section 132 respectively.

[0075] In some embodiments, refer to Figure 2 and Figure 4, this application further includes a light-shielding tape 50, a driving chip 60, a printed circuit board 70, and a flexible circuit board 80. The display panel 30 includes a color filter substrate 35 and a thin film transistor substrate 36. The driving chip 60 is disposed on a side of the thin film transistor substrate 36 facing away from the main body 110, the printed circuit board 70 is disposed on a side of the main body 110 facing away from the display panel 30, one end of the flexible circuit board 80 is connected to the printed circuit board 70, and the other end of the flexible circuit board 80 is connected to the driving chip 60. The color filter substrate 35 is disposed on a side of the thin film transistor substrate 36 facing away from the main body 110. A part of the light-shielding tape 50 is connected to the color filter substrate 35, and another part of the light-shielding tape 50 is connected to a side of the main body 110 facing away from the display panel 30. The light-shielding tape 50 covers the driving chip 60, the printed circuit board 70, and the flexible circuit board 80. The light-shielding layer 40 is used to cover the driving chip 60, the printed circuit board 70, and the flexible circuit board 80 to prevent a user from seeing parts (terminal areas) other than the display area 392 when viewing the display screen of the display module 1, thereby ensuring the display screen of the display module 1.

[0076] See Figure 4 , in an embodiment of the present application, that is, on the display panel 30 on the lower side of the display module 1, the size of the color filter substrate 35 is smaller than the size of the thin film transistor substrate 36, so that there is an exposed mounting area on a side of the thin film transistor substrate 36 facing away from the backlight module 10. The mounting area corresponds to the terminal area, and the driving chip 60 is disposed on the mounting area. A side of the thin film transistor substrate 36 facing the backlight module 10 is bonded to the second horizontally bent section 132 through a second bonding portion 90.

[0077] In some embodiments, see Figures 5 - 7 , a first chamfer 37 is formed between the first end face 31 and the first side face 33, and at least a part of the light-shielding layer 40 covers the first chamfer 37. In the processing technology of the light-shielding layer 40 of the present application, first, an ink material is coated on the second end face 32, and then the ink material flows from the second end face 32 along the first side face 33 to the first end face 31, so as to realize that the light-shielding layer 40 covers the first end face 31, the first side face 33, and the second end face 32. However, the applicant found in the processing process that since the first side face 33 is perpendicular to the first end face 31, when the ink material flows from the first side face 33 to the first end face 31, most of the ink material slides from the first side face 33 to the ground, and only a small part flows along the first side face 33 to the first end face 31, resulting in inconsistent thicknesses of the light-shielding layer 40 on the first end face 31 and the first side face 33. In the present application, the first chamfer 37 is provided to enable the ink material to flow to the first side face 33 after being buffered by the first chamfer 37, thereby reducing the flow rate of the ink material, so that the thicknesses of the light-shielding layer 40 on the first end face 31 and the first side face 33 are substantially the same.

[0078] In some embodiments, seeFigures 5 - 7 A second chamfer 38 is formed between the second end face 32 and the first side face 33. At least a part of the light-shielding layer 40 covers the second chamfer 38. In the processing technology of the light-shielding layer 40 of the present application, the applicant found that since the first side face 33 and the second end face 32 are perpendicular, when the ink layer flows from the second end face 32 along the first side face 33 to the first end face 31, due to the high perpendicularity of the first side face 33, the flow rate of the ink material is relatively fast, resulting in inconsistent thicknesses of the light-shielding layer 40 on the first end face 31, the first side face 33, and the second end face 32. The applicant forms the second chamfer 38 between the second end face 32 and the first side face 33. The second chamfer 38 serves as a buffer slope for the ink material to flow from the second end face 32 to the first side face 33, enabling the ink material to flow from the second end face 32 to the first side face 33 through the first chamfer 37. Compared with the scheme where the second end face 32 and the first side face 33 are perpendicular, the ink material of the present application first passes through the buffer of the first chamfer 37 and then flows to the first side face 33, thereby reducing the flow rate of the ink material, so that the thicknesses of the light-shielding layer 40 on the second end face 32 and the first side face 33 are substantially the same.

[0079] In some embodiments, referring to Figures 5 - 7 the width of the part of the light-shielding layer 40 covering the second end face 32 is a, and the width of the part of the light-shielding layer 40 covering the first end face 31 is b, satisfying: a < b. The light emitted by the backlight module 10 of the present application passes through the second end face 32 after passing through the first end face 31. The second end face 32 is the side facing the user. In order to increase the display area 392 of the second end face 32, the range of the light-shielding layer 40 covering the second end face 32 is relatively small to increase the display area 392 of the second end face 32. However, when the range of the light-shielding layer 40 covering the second end face 32 is relatively small, there will be a problem of light leakage at the edge position of the display panel 30. The present application increases the width of the part of the light-shielding layer 40 covering the first end face 31 compared with the width of the part of the light-shielding layer 40 covering the second end face 32, increasing the light-shielding width of the first end face 31, that is, blocking the light in a larger range at the edge of the light-incident end face of the display panel 30, thereby improving the light-shielding effect of the display panel 30, so that the light-shielding layer 40 of the present application can increase the display area 392 of the second end face 32 on the one hand, and on the other hand, solve the problem of light leakage at the edge due to the relatively large display area 392.

[0080] In some embodiments, 0.15 mm ≤ a ≤ 0.3 mm; 1.5a ≤ b ≤ 3a.

[0081] Figure 6 shows Figure 3 an enlarged schematic view of A (showing a schematic structural view of a display panel in another embodiment), Figure 7 shows Figure 3Schematic enlarged view of A (showing the schematic structure of the display panel in another embodiment). In some embodiments, refer to Figure 6 and Figure 7 , the first side surface 33 includes a recessed portion 331, and the light-shielding layer 40 at least partially covers the recessed portion 331. By providing the recessed portion 331 in this application, the area of the first side surface 33 is increased, thereby increasing the coverage area of the light-shielding layer 40, and further improving the light-shielding effect of the light-shielding layer 40.

[0082] Exemplarily, the recessed portion 331 can be set as an arc-shaped groove, a square groove or an irregular groove, as long as the area of the first side surface 33 is increased, and it is not limited in this application.

[0083] It can be understood that in this application, the area of the first side surface 33 can also be increased by providing a protruding portion on the first side surface 33 of the display panel 30.

[0084] In some embodiments, refer to Figure 7 , the first side surface 33 includes a plurality of ridges 332 protruding away from the display panel 30, and the light-shielding layer 40 at least partially covers the ridges 332. The provision of the plurality of ridges 332 can increase the area of the first side surface 33.

[0085] In some embodiments, the thickness of the light-shielding layer 40 is greater than 2 um and less than 15 um. Thus, the light-shielding effect of the light-shielding layer 40 on light can be controlled by changing the thickness of the light-shielding layer 40.

[0086] Exemplarily, the thickness of the light-shielding layer 40 can be 3 um, 4 um, 5 um, 6 um, 7 um or 8 um, etc.

[0087] Figure 8 Shows Figure 2 Cross-sectional view of A-A (showing the schematic structure of the display module in another embodiment). In some other embodiments, refer to Figure 8, the backlight module 10 further includes a first polarizer 140, a second polarizer 150, a first reflector 160, a rubber frame 170, a light guide plate 180, and an optical film layer 190. The first reflector 160 is disposed on one side of the main body 110 facing the display panel 30. The light guide plate 180 is disposed on one side of the first reflector 160 facing the display panel 30. The optical film layer 190 is disposed on one side of the light guide plate 180 facing the display panel 30. The first polarizer 140 is disposed on the first end face 31, and the second polarizer 150 is disposed on the second end face 32. The rubber frame 170 is disposed between the light guide plate 180 and the first side plate 120. The first bonding portion 20 at least partially extends to one end of the rubber frame 170 away from the main body 110. The rubber frame 170 is bonded to the first end face 31 through the first bonding portion 20. The rubber frame 170 can support the display panel 30, thereby improving the connection stability between the display panel 30 and the backlight module 10.

[0088] In some embodiments, referring to Figure 8 , the backlight module 10 further includes a support block 200. One end of the support block 200 is connected to the optical film layer 190, and the other end of the support block 200 is connected to the first end face 31. In this application, the support of the display panel 30 is achieved through the setting of the support block 200, so that a gap is formed between the display panel 30 and the optical film layer 190, avoiding the problem that the optical film layer 190 has wrinkles due to the display panel 30 being directly pressed on the optical film layer 190.

[0089] In some embodiments, referring to Figure 8 , the backlight module 10 further includes a light-shielding block 210. The light-shielding block 210 is disposed between the first side plate 120 and the light guide plate 180, and can absorb the light at the edge positions of the optical film material and the light guide plate 180. Preferably, the light-shielding block 210 is a black light-absorbing block.

[0090] In the embodiment of this application, the first bonding portion 20 is a hot melt adhesive. The connection between the display panel 30 and the first side plate 120 is achieved by coating the hot melt adhesive on the first side plate 120 to solve the problem of separation between the display panel 30 and the backlight module 10.

[0091] In some embodiments, the distance between the side edge of the second polarizer 150 and the first side face 33 is c, satisfying: 0.15 mm ≤ c ≤ 0.3 mm.

[0092] As another aspect of the embodiments of the present disclosure, the embodiments of the present disclosure provide a display device, which includes the display module 1 as described above. Thus, the display device has all the features and advantages of the front double-sided display module 1, which will not be elaborated herein. Generally speaking, the display panel 30 of the display device is connected to the first side plate 120 through the first bonding portion 20, thereby realizing the fixation between the display panel 30 and the backlight module 10. Secondly, in the present application, the display panel 30 is arranged outside the accommodation space, thereby canceling the size limitation of the first side plate 120 and the back plate 100 on the display panel 30, so that the size of the display panel 30 in the present application is larger than the size of the backlight module 10 when designed. When the user views the display module 1, the backlight module 10 is located on the side of the display panel 30 facing away from the user, and the user can only see the existence of the display panel 30, thereby realizing the full-screen effect of the display module 1. Furthermore, the orthographic projection of the first side plate 120 of the present application on the display panel 30 is located within the display area 392, so that the size of the display panel 30 in the present application is larger than the size of the backlight module 10. At the same time, in the present application, a light-shielding layer 40 is provided on the first side surface 33, the first end surface 31 and the second end surface 32 at the edge of the display panel 30 to shield the light at the edge position of the display panel 30, preventing the light emitted by the backlight module 10 from leaking from the edge of the display panel 30, thereby improving the problem of brightening around the display panel 30. Further, in the present application, the display panel 30 is directly used as the glass cover plate of the present application, and the light shielding of the edge of the display panel 30 can be realized only through a relatively small range of the light-shielding layer 40, which can effectively realize the full-screen effect of the display module 1 without causing light leakage of the display panel 30. Further, the backlight module 10 of the present application occupies a relatively small range of the display panel 30, thereby realizing the narrow-bezel effect of the display module 1.

[0093] It should be noted that, in addition to the display module 1, the display device further includes other necessary components and compositions, such as a housing, a circuit board, a power cord, etc. Those skilled in the art can make corresponding supplements according to the specific usage requirements of the display device, which will not be elaborated herein.
