Description

Technical Field

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

[0002] Laptop display modules mainly have two structures: flat and bent. Flat display modules require a support structure to fix the circuit board. In existing technologies, the support structure and backplate are often integrally formed by mechanical cutting (i.e., a hole is cut in the backplate). Because there is no reliable support at the hole location, the strength of the backplate and the support strength are affected. The flexible circuit board connected to the light-emitting elements is prone to bulging at the hole location during reliability testing, resulting in uneven brightness or spot phenomena, specifically manifested as abnormal bright spots or shadows in certain areas of the screen. Utility Model Content

[0003] In view of this, this application provides a display module and display device that can effectively reduce back panel holes, while improving the strength of the back panel and the support members, thereby avoiding abnormal bright spots or shadows.

[0007] In some embodiments of this application, the support member includes: a first support portion, which is fixedly connected to at least one of the base plate, the side plate and the top plate; and a second support portion, which is connected to the first support portion and is fixedly or detachably connected to the circuit board.

[0008] In some embodiments of this application, the support member further includes a bending portion, wherein the first support member is connected to the second support member through the bending portion, and the bending portion bends to form a clearance space; wherein the orthographic projection of the end of the circuit board near the display panel on the support member falls within the clearance space.

[0009] In some embodiments of this application, the support member further includes a first hook portion, which is fixedly or detachably connected to the side of the second support member away from the circuit board;

[0010] The display module also includes a fixing member, and the circuit board is connected to the second support part through the fixing member. The portion of the second fixing member extending from the second support part is received in the first hanging ear part.

[0011] In some embodiments of this application, the first support portion is connected to the top plate and located between the display component and the top plate, and the support member further includes a support main body portion, wherein the first support portion is a part of the support main body portion;

[0012] The backlight assembly also includes a middle frame and a first reflective sheet. The back plate and the display panel are respectively fixed to the middle frame. The two ends of the supporting main body are fixedly connected to the middle frame. The first reflective sheet is located on the side of the light guide plate away from the bottom plate.

[0013] The backlight assembly further includes an optical functional film layer located on the side of the light guide plate away from the base plate and including a second hanging ear portion. The second hanging ear portion is located between the supporting main body portion and the first reflective sheet and is connected to an adhesive layer fixed to the middle frame and the back plate.

[0014] In some embodiments of this application, the optical functional film layer includes a plurality of optical functional films, which are stacked in the stacking direction of the display component and the backlight component; each optical functional film includes a sub-hook portion, and the plurality of sub-hook portions are spaced apart in a uniform direction between the support body portion and the first reflective sheet and are respectively connected to the adhesive layer.

[0015] In some embodiments of this application, the backlight assembly further includes a light guide plate, a light-emitting element, and a first flexible circuit board.

The display assembly is located on the light-emitting side of the backlight assembly and includes a circuit board. The circuit board is fixedly or detachably connected to the support member, and the rigidity of the support member is greater than that of the backplate. By separating the support member and the backplate, the support member can be manufactured separately, and the backplate does not need to be cut, meaning there will be no holes in the backplate. The strength of the backplate is enhanced, so the flexible circuit board connected to the light-emitting element is less likely to bulge at the hole location during reliability testing, preventing abnormal bright spots or shadows in certain areas of the screen. In addition, the rigidity of the support member is greater than that of the backplate, which enhances the strength of the support member. Attached Figure Description

[0036] The display module and display device provided in this application will be described in detail below with reference to specific embodiments and accompanying drawings.

[0037] Please see Figures 1 to 6 This application provides a display module 110, which includes a display component 101 and a backlight component 102. The display component 101 includes a circuit board 12 and is located on the light-emitting side of the backlight component 102. The backlight component 102 includes a back plate 21 and a support member 22 connected to the back plate 21. The circuit board 12 is fixedly or detachably connected to the support member 22. The support member 22 has a higher hardness than the back plate 21.

[0038] This application separates the support member 22 and the back plate 21. The support member 22 can be manufactured independently, and the back plate 21 does not require cutting, meaning there will be no holes in the back plate 21. This enhances the strength of the back plate 21, preventing the flexible circuit board connected to the light-emitting element 240 from bulging at the hole location during reliability testing, thus avoiding abnormal bright spots or shadows in certain areas of the screen. Furthermore, the support member 22 has a higher hardness than the back plate 21, further strengthening the support member 22. Additionally, the separate design of the support member 22 and the back plate 21 allows for the replacement of the appropriate support member 22 as needed, facilitating the adjustment of the position of the first hanging ear 225 and improving the versatility of the back plate 21 mold.

[0039] Please see Figure 1 , Figure 5 and Figure 6In some embodiments of this application, the back plate 21 includes a bottom plate 211, a side plate 212, and a top plate 213. The two ends of the side plate 212 are fixedly connected to the bottom plate 211 and the top plate 213, respectively. The display assembly 101 also includes a display panel 11, which is electrically connected to the circuit board 12. The top plate 213 is located between the bottom plate 211 and the display panel 11. The end of the support member 22 away from the circuit board 12 is connected to at least one of the bottom plate 211, the side plate 212, and the top plate 213. Please refer to [link to relevant documentation]. Figure 2 The end of the support member 22 furthest from the circuit board 12 is connected to the top plate 213, which helps to provide flat support for the display panel 11 (see below). The end of the support member 22 furthest from the circuit board 12 is connected to the bottom plate 211 or the side plate 212, which facilitates the replacement of the support member 22 at any time. Please refer to [link to relevant documentation]. Figure 5 The end of the support member 22 furthest from the circuit board 12 is connected to the side plate 212. (See also...) Figure 6 The end of the support member 22 away from the circuit board 12 is connected to the extension portion 2111 of the base plate 211, and is also connected to the side plate 212. Figure 1 , Figure 5 and Figure 6 The connection relationship between the back plate 21 and the support member 22 is only for illustration and does not represent all connection relationships.

[0040] In some embodiments of this application, the support member 22 includes a first support portion 221 and a second support portion 222. The first support portion 221 is fixedly connected to the top plate 213 and located between the display panel 11 and the top plate 213. The second support portion 222 is connected to the first support portion 221 and is fixedly or detachably connected to the circuit board 12.

[0041] In some embodiments of this application, the support member 22 further includes a bending portion 223, through which the first support portion 221 is connected to the second support portion 222, and the bending portion 223 bends to form a clearance space 224. The orthographic projection of the end of the circuit board 12 near the display panel 11 onto the support member 22 falls within the clearance space 224.

[0042] In some embodiments of this application, the support member 22 further includes a first hook portion 225, which is fixedly or detachably connected to the side of the second support member 222 away from the circuit board 12. The display module 110 further includes a fixing member 226, through which the circuit board 12 is connected to the second support member 222, and the portion of the second fixing member 226 extending from the second support member 222 is received within the first hook portion 225.

[0043] In some embodiments of this application, the portion of the second fastener 226 extending from the second support portion 222 is threadedly connected to the first lug portion 225.

[0044] In some embodiments of this application, the support member 22 and the back plate 21 can be connected by at least one of welding, bonding, bolting, or other methods.

[0045] In some embodiments of this application, the thickness of the back plate 21, the bending portion 223, the first support portion 221, and the second support portion 222 is less than 0.3 mm. In this embodiment, the thickness of the back plate 21, the bending portion 223, the first support portion 221, and the second support portion 222 is 0.2 mm.

[0046] Since no holes appear on the back plate 21 and the strength of the support member 22 is enhanced, the thickness of the back plate 21, the bending portion 223, the first support portion 221, and the second support portion 222 can be reduced. Because the thickness of the back plate 21, the bending portion 223, the first support portion 221, and the second support portion 222 is reduced, compared to the prior art where the one-piece back plate 21 and support member 22 are made of the same material with a relatively lower hardness than the support member 22 of this application (the thickness of the one-piece back plate 21 and support member 22 is 0.3 mm), the total weight of the back plate 21 and the support member 22 is reduced. That is, the back plate 21 and support member 22 of the display module 110 provided in this application contribute to the lightweighting of the display module 110.

[0047] In this embodiment, the back plate 21 is made of high-strength aluminum, and the support member 22 is made of a high-hardness material, such as SUS304 stainless steel. In other embodiments, the materials of the back plate 21 and the support member 22 can be selected according to actual needs, as long as the hardness of the support member 22 is greater than that of the back plate 21.

[0048] In some embodiments of this application, the support member 22 further includes a support body 220, and the first support portion 221 is a part of the support body 220. The backlight assembly 102 further includes an optical functional film layer 27, which is located on the side of the light guide plate 25 away from the base plate 211 and faces the display panel 11. The optical functional film layer 27 includes a second hook portion 275, which is located between the support body 220 and the light guide plate 25 (see below) and connected to an adhesive layer 243 fixed to the middle frame 24 and the back plate 21. The support body 220 can provide complete planar support for the display panel 11, effectively reducing the risk of breakage.

[0049] In some embodiments of this application, the optical functional film layer 27 includes a plurality of optical functional films, which are stacked in the stacking direction of the display component 101 and the backlight component 102. Each optical functional film includes a sub-hook portion, and the plurality of sub-hook portions are spaced apart in a uniform direction between the support body portion 220 and the light guide plate 25 and are respectively connected to the adhesive layer 243.

[0050] In some embodiments of this application, the optical functional film layer 27 includes a first diffuser 271, a first brightness enhancement film 273, a second diffuser 272, and a second brightness enhancement film 274. The first diffuser 271 is located on the light guide plate 25, the first brightness enhancement film 273 is located on the first diffuser 271, the second brightness enhancement film 274 is located on the first brightness enhancement film 273, and the second diffuser 272 is located on the second brightness enhancement film 274 and faces the display panel 11. Light emitted from the light guide plate 25 enters the first diffuser 271 and the second diffuser 272 and is diffused; light emitted from the light guide plate 25 enters the first brightness enhancement film 273 and the second brightness enhancement film 274 and is refracted, thereby increasing the brightness of the display panel 11.

[0051] Of course, in other embodiments, the optical functional film layer 27 is not limited to diffuser and brightener, and can be designed according to actual conditions. The arrangement of the first diffuser 271, the first brightener 273, the second diffuser 272 and the second brightener 274 is not limited to the above arrangement and can be set according to actual conditions.

[0052] In some embodiments of this application, the first diffuser 271 includes a first sub-ear 2711, the first brightness enhancement film 273 includes a second sub-ear 2721, the second diffuser 272 includes a third sub-ear 2731, and the second brightness enhancement film 274 includes a fourth sub-ear 2741. The first sub-ear 2711, the second sub-ear 2721, the third sub-ear 2731, and the fourth sub-ear 2741 are arranged sequentially at intervals along the same direction and are fixedly connected to the first reflector 261. The second ear 275 includes the first sub-ear 2711, the second sub-ear 2721, the third sub-ear 2731, and the fourth sub-ear 2741.

[0053] In other embodiments, as the number of optical functional film layers 27 increases, the number of sub-hoops included in the second hook portion 275 also increases. That is, the number of sub-hoops included in the second hook portion 275 is equal to the number of films included in the optical functional film layer 27.

[0054] In some embodiments of this application, the backlight assembly 102 further includes a light guide plate 25, a light-emitting element 240, and a first flexible circuit board 230. The light-emitting element 240 is located on one side of the light guide plate 25. The light guide plate 25 and the first flexible circuit board 230 are fixed to the base plate 211. The light-emitting element 240 is located on the side of the first flexible circuit board 230 away from the base plate 211 and is electrically connected to the first flexible circuit board 230. The area where the base plate 211 contacts the first flexible circuit board 230 remains continuous and uninterrupted. That is, in this embodiment, the back plate 21 does not form a hollow structure, opening, or hole at the position corresponding to the first flexible circuit board 230. Thus, during the thermal shock test, when the light guide plate 25 repeatedly expands and contracts, it will not pull on the first flexible circuit board 230, causing the first flexible circuit board 230 to shift outwards towards the hollow area and wrinkle, thereby causing the light-emitting element 240 connected to the first flexible circuit board 230 to misalign and produce a light shadow.

[0055] In some embodiments of this application, the backlight assembly 102 further includes a first reflective sheet 261. The first reflective sheet 261 is located on the surface of the top plate 213 away from the display panel 11 and is connected to the optical functional film layer 27. The first reflective sheet 261 is positioned opposite to the light-emitting element 240 and part of the light guide plate 25. The first reflective sheet 261 is used to reflect light exposed from the side of the light guide plate 25 away from the back plate 21 back into the light guide plate 25, thereby improving light utilization efficiency.

[0056] In some embodiments of this application, the backlight assembly 102 further includes a middle frame 24, and the back plate 21 is fixedly connected to the middle frame 24. The middle frame 24 includes a frame body 241, which is disposed on the four edges of the back plate 21. The middle frame 24 and the back plate 21 define a receiving groove 23, and the optical functional film layer 27, the light guide plate 25, the light-emitting element 240, etc. are housed in the receiving groove 23.

[0057] In some embodiments of this application, the middle frame 24 further includes a third support portion 242, which extends from the frame 241 into the receiving groove 23. The third support portion 242 includes a first support surface and a second support surface, which are disposed opposite to each other in the stacking direction of the display assembly 101 and the backlight assembly 102. Both ends of the support body 220 are respectively fixed to the first support surface. The second support surface faces the light guide plate 25 or the first reflective sheet 261.

[0058] In some embodiments of this application, the first sub-hook portion 2711, the second sub-hook portion 2721, the third sub-hook portion 2731, and the fourth sub-hook portion 2741 are located within the cavity formed by the third support portion 242 and the top plate 213. The first reflective sheet 261 is attached to the second support surface of the third support portion 242 via an adhesive layer 243. The first sub-hook portion 2711, the second sub-hook portion 2721, the third sub-hook portion 2731, and the fourth sub-hook portion 2741 are attached to the adhesive layer 243 and connected to the support body portion 220. Thus, the support body portion 220 can provide complete planar support for the first sub-hook portion 2711, the second sub-hook portion 2721, the third sub-hook portion 2731, and the fourth sub-hook portion 2741 of the optical functional film layer 27, effectively reducing the risk of breakage of the optical functional film layer 27.

[0059] In some embodiments of this application, the backlight assembly 102 further includes a second reflective sheet 262, which is located between the light guide plate 25 and the base plate 211 and on the side of the first flexible circuit board 230 away from the side plate 212. The second reflective sheet 262 is used to reflect light exposed from the side of the light guide plate 25 facing the back plate 21 back into the light guide plate 25 to improve light utilization efficiency.

[0060] In some embodiments of this application, the backlight assembly 102 further includes a light-shielding adhesive located in the non-display area of ​​the display panel 11. One end of the light-shielding adhesive is located between the second frame 241 and the display panel 11, and the other end is located between the first polarizer and the optical functional film layer 27. The light-shielding adhesive is used to block light entering the non-display area of ​​the display panel 11 from the light guide plate 25 to prevent light leakage, avoid "halo" or "light leakage" phenomena at the screen edges, and improve display contrast. In addition, the matte surface of the light-shielding adhesive can scatter / absorb reflected light, reducing optical path interference.

[0061] The display component 101 further includes a display panel 11 and a second flexible circuit board 13 connected to the display panel 11, wherein the second flexible circuit board 13 is electrically connected to the circuit board 12.

[0062] In this embodiment, the end of the second flexible circuit board 13 connected to the display panel 11 and the end connected to the circuit board 12 are on the same horizontal plane. The second flexible circuit board 13 does not need to be bent, which can reduce the requirement for high flexibility of the second flexible circuit board 13.

[0063] The display panel 11 includes an array substrate 111 and a color filter substrate 112, which are stacked together. The array substrate 111 is located on the top plate 213, and one end of the second flexible circuit board 13 is electrically connected to the array substrate 111. The display panel 11 also includes a liquid crystal (not shown), which is located between the array substrate 111 and the color filter substrate 112.

[0064] The display component 101 further includes a first polarizer and a second polarizer. The first polarizer is located on the side of the array substrate 111 closer to the backlight component 102, and the second polarizer is located on the side of the color filter substrate 112 away from the array substrate 111.

[0065] Please see Figure 7 Secondly, this application also provides a display device 100, which includes the display module 110 as described above.

[0066] In this embodiment, the display device 100 can be a laptop, a display screen, a mobile phone, etc.

[0067] In summary, although the present application has disclosed the preferred embodiments as described above, the above preferred embodiments are not intended to limit the present application. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present application.
