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] In existing technology, light-shielding tape is used to bond the backlight module to the display panel. In order to avoid displacement of the optical film in the backlight module and wrinkles after the reliability test of the optical film due to the large bonding area, the light-shielding tape is usually designed to bond the top layer of the backlight module film in segments. This design usually results in uneven brightness because the area where the light-shielding tape is bonded to the optical film is prone to shine due to excess adhesive at the edges.

Furthermore, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0020] This application provides a display module, such as... Figures 1-4 As shown, the display module includes: an optical module 3 and a light-shielding part 22; The light-shielding part 22 is located on one side of the light-emitting surface of the optical module 3; The light-shielding part 22 includes an opening area 40, and in the direction perpendicular to the optical module 3, the orthographic projection of the opening area 40 falls into the orthographic projection of the optical module 3. The light-shielding part 22 includes: a light-shielding layer 34, and an adhesive layer 33 located on the side of the light-shielding layer 34 facing the optical module 3; The adhesive layer 33 includes a removal area 3301, and the orthographic projection of the removal area 3301 overlaps with the orthographic projection of the optical module 3 in a direction perpendicular to the optical module 3.

[0021] The display module provided in this application embodiment has an adhesive layer in the light-shielding part including a removal area. The removal area overlaps with the orthographic projection of the optical module. The removal area is located near the edge of the light-shielding part, which can alleviate the uneven brightness caused by excess adhesive in the light-shielding part and improve the uniformity of the light output brightness of the display module.

[0022] It should be noted that, it should be noted that, Figure 3 For along Figure 2 Cross-sectional view of AA'. Figure 4 For along Figure 2 Cross-sectional view of BB'.

[0023] It should be noted that in the display module provided in this application embodiment, the removal area refers to the area located on the same layer as the adhesive layer but without adhesive layer material. That is, in the removal area, the side of the light-shielding layer facing the optical module does not include adhesive layer material.

[0024] In some embodiments, such as Figures 1-4 As shown, the removal area 3301 includes: a first removal area 3301-1 located between the adhesive layer 33 and the opening area 40; In the direction perpendicular to the optical module 3, the orthographic projection of the first removal area 3301-1 falls into the orthographic projection of the optical module 3.

[0025] In some embodiments, such as Figures 1-4 As shown, the edge of the first removal area 3301-1 on the side away from the adhesive layer 33 coincides with the edge of the light-shielding portion 22. That is, the adhesive layer 33 in the edge portion of the light-shielding portion 22 is removed, and on the side facing the opening area 40, the distance between the edge of any area of ​​the adhesive layer 33 in the orthographic projection of the light-shielding layer 34 and the edge of the light-shielding layer 34 is greater than 0.

[0026] In some embodiments, such as Figure 2 , Figure 4 As shown, the removal area 3301 also includes: a plurality of second removal areas 3301-2; The second removal area 3301-2 is located between the first removal area 3301-1 and the adhesive layer 33; a plurality of second removal areas 3301-2 are spaced apart in the extension direction of the first removal area 3301-1; In the direction perpendicular to the optical module 3, the orthographic projection of the second removal region 3301-2 overlaps with the orthographic projection of the optical module 3.

[0027] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, in the extension direction perpendicular to the first removal area 3301-1, the width h1 of the first removal area 3301-1 is greater than or equal to 0.2 mm, and the width h1 of the first removal area 3301-1 is less than the width d1 of the overlapping area of ​​the light-shielding part 22 and the orthographic projection of the optical module 3 in the direction perpendicular to the optical module 3.

[0028] It should be noted that the cutting tolerance of the light-shielding part is typically about 0.15 mm, and the glue overflow width is about 0.05 mm to 1 mm. In the display module provided in this application embodiment, h1 is greater than or equal to 0.2 mm, which can avoid glue overflow while taking into account the cutting tolerance. Furthermore, the width of the first removal area is less than the width of the orthographic projection of the light-shielding part and the optical module in the direction perpendicular to the optical module, which can also prevent the removal area from being too large and affecting the bonding effect.

[0029] In some embodiments, such as Figure 2 , Figure 4 As shown, in the extension direction perpendicular to the first removal area 3301-1, the width h2 of the second removal area 3301-2 is greater than or equal to d1+0.15 mm and less than or equal to d2+0.15 mm. Wherein, d2 is: the distance between the edge of the orthogonal projection of the light-shielding part 22 toward the opening area 40 and the orthogonal projection edge of the frame 2 in the direction perpendicular to the optical module 3.

[0030] It should be noted that the second removal area is the non-bonded area between the adhesive layer and the optical module. Considering the cutting tolerance of the light-shielding part, h2 is greater than or equal to d1-0.15 mm and less than or equal to d1+0.15 mm.

[0031] In some embodiments, such as Figure 4 As shown, the thickness h4 of the adhesive layer 33 is greater than or equal to 0.01 mm and less than or equal to 0.15 mm.

[0032] This avoids light leakage caused by a large longitudinal gap between the optical film and the light-shielding layer in the removal area.

[0033] In some embodiments, h4 is 0.01 mm.

[0034] Alternatively, in some embodiments, such as Figure 5 , Figure 6 As shown, the adhesive layer 33 includes a first sub-region 3302 and a second sub-region 3303 located between the first sub-region 3302 and the opening region 40, and the removal region 3301 is located between the first sub-region 3302 and the second sub-region 3303.

[0035] It should be noted that, Figure 6 For along Figure 5 Cross-sectional view of CC'.

[0036] In some embodiments, such as Figure 5 , Figure 6As shown, in the extension direction perpendicular to the removal area 3301, the width h3 of the second sub-region 3303 is greater than or equal to 0.15 mm and less than or equal to d1, and the width h1 of the removal area 3301 is greater than or equal to d2-d1+0.15 mm and less than or equal to d2-h3.

[0037] In some embodiments, h3 is 0.5 mm and h1 is 0.2 mm.

[0038] In some embodiments, the thickness of the light-shielding layer is 0.05 mm. The light-shielding layer is, for example, a black substrate.

[0039] In some embodiments, such as Figure 3 , Figure 4 , Figure 6 As shown, the display module also includes a frame 2 and a backplate 1; The back panel 1 includes: a bottom plate 4 and a side plate 5 connected to the bottom plate 4 on one side; the bottom plate 4 and the side plate 5 form an accommodating space 6; Optical module 3 is located within the accommodating space 6; The frame 2 includes an inner frame 201 located on the side of the side panel 5 facing the receiving space 6, and the adhesive layer 33 is in contact with the inner frame 201.

[0040] In some embodiments, such as Figure 3 , Figure 4 , Figure 6 As shown, the optical module 3 includes: a light guide plate 301 and a multilayer optical film 302 located on the side of the light guide plate 301 away from the base plate 4; the multilayer optical film 302 includes, for example, a quantum dot film 3021, a diffuser 3022, a prism sheet 3023 and a brightness enhancement film 3024 stacked sequentially on the side of the light guide plate 301 away from the base plate 4.

[0041] In some embodiments, such as Figure 3 , Figure 4 , Figure 6 As shown, the display module also includes a reflective sheet 30 located between the base plate 4 and the light guide plate 301, and an adhesive material 25 located between the inner frame 201 and the side plate 5; that is, the inner frame 201 and the side plate 5 are connected by the adhesive material 25.

[0042] In some embodiments, the display module further includes a light source assembly; the light source assembly is located on the side of the light guide plate, and the light emitted by the light source assembly is incident from the side of the light guide plate.

[0043] In some embodiments, the light source assembly includes a plurality of light-emitting devices. The light source assembly is, for example, a light strip provided with a plurality of light-emitting devices. The light-emitting devices are, for example, inorganic light-emitting diodes (LEDs).

[0044] In some embodiments, such as Figure 7As shown, the display module includes multiple corner areas 7; the light-shielding part 22 includes multiple sub-light-shielding parts 22-1; the sub-light-shielding parts 22-1 are connected in the corner areas 7; and in the corner areas 7, two sub-light-shielding parts 22-1 overlap between their orthographic projections on the base plate 4.

[0045] In some embodiments, such as Figure 8 As shown, the side panel 5 includes a first opening 8 located in the corner area 7; the opening direction of the first opening 8 is the side of the side panel 5 away from the bottom plate 4. In the area corresponding to the first opening 8, the distance between the surface of the side plate 5 facing away from the bottom plate 4 and the bottom plate 4 is the first distance H1; in the area outside the first opening 8, the distance between the surface of the side plate 5 facing away from the bottom plate 4 and the bottom plate 4 is the second distance H2; the second distance H2 is greater than the first distance H1.

[0046] In some embodiments, such as Figure 9 As shown, the distance between the surface of the inner frame 201 facing away from the base plate 4 and the base plate 4 is the third distance H3; at least in the corner area, the third distance H3 of the inner frame 201 is greater than the first distance H1, and the third distance H3 is less than the second distance H2. The third distance corresponding to the inner frame located in at least some corner areas is greater than the first distance and less than the second distance, that is, in at least some corner areas, the inner frame located inside the side plate no longer acts as a barrier, thereby avoiding the frame from sinking inward and improving the yield of the display module.

[0047] In some embodiments, such as Figure 8 , Figure 9 As shown, the side plate 5 includes: a corner sub-side plate 501 located in the corner area 7, and a connecting sub-side plate 502 located outside the corner area 7. The extension directions of the two connecting sub-side plates 502 connected at both ends of the corner sub-side plate 501 intersect each other.

[0048] Specifically, the distance between the surface of the connecting sub-side plate 502 facing away from the base plate 4 and the base plate 4 is the second distance H2.

[0049] In some embodiments, such as Figure 10 As shown, the light-shielding part 22 includes: a first light-shielding part 2201 located at least on the side of the frame 2 away from the bottom plate 4, and a second light-shielding part 2202 connected to the first light-shielding part 2201; the first light-shielding part 2201 includes a removal area (not shown). The first light-shielding part 2201 extends to at least part of the corner area 7, and the second light-shielding part 2202 is connected to the first light-shielding part 2201 in the corner area 7. The second light-shielding part 2202 is located on the side of the side panel 5 away from the receiving space 6. The adhesive layer (not shown) of the second light-shielding part 2202 is in contact with the side plate 5.

[0050] The display module provided in this application embodiment has a light-shielding part that extends to the corner area and the side of the side panel, so that the light-shielding part can cover at least a portion of the first opening in the corner area, thereby preventing light leakage from the display module at the first opening and improving the display effect.

[0051] In some embodiments, such as Figure 10 As shown, the second light-shielding part 2202 covers a portion of the surface of the corner sub-side plate 501 away from the receiving space 6, and the second light-shielding part 2202 also covers a portion of the surface of the two connecting sub-side plates 502 connected to the corner sub-side plate 501 away from the receiving space 6.

[0052] The display module provided in this application embodiment has a light-shielding part that extends beyond the corner area and covers a portion of the side of the connecting sub-side panel, thereby improving the covering effect of the light-shielding part, further preventing light leakage at the first opening of the display module, and improving the display effect.

[0053] In some embodiments, such as Figure 11 , Figure 12 , Figure 13 As shown, the side plate 5 also includes: a plurality of first sub-side plates 503; The first sub-side plate 503 is located on the side of the connecting sub-side plate 502 away from the receiving space 6, and the connecting sub-side plate 502 and the first sub-side plate 503 are connected at the end away from the bottom plate 4. The first sub-side plate 503 extends to the corner area 7, and extends to the point where it is disconnected from the two first sub-side plates 503 in the same corner area 7.

[0054] The display module provided in this application embodiment further includes a first sub-side plate bent to the outside of the connecting sub-side plate, and the first sub-side plate extends to the corner area. That is, the dimension of the separation between the two first sub-side plates extending to the same corner area is smaller than the dimension of the first opening, which can improve the support strength of the back plate. It can also alleviate the problem of light leakage of the display module in the first opening area.

[0055] In some embodiments, when the side panel includes a first sub-side panel, in the corner area of ​​the light-emitting side, namely the third corner area and the fourth corner area, the frame only includes the first sub-frame located inside the side panel, and does not include the second sub-frame that overlaps with the side panel.

[0056] In some embodiments, such as Figure 12 , Figure 13 As shown, the first sub-side panel 503 includes: a first portion 19 located in the corner area 7, and a second portion 20 located outside the corner area 7; The first part 19 includes a second opening 1901; the second opening 1901 is located on the side of the first part 19 away from the base plate 4 and is adjacent to the second part 20.

[0057] The display module provided in this application embodiment forms a second opening on the side of the first part close to the second part, which can avoid deformation when the first part is formed.

[0058] In some embodiments, such as Figure 14 As shown, in the area corresponding to the first opening 8, the side plate 5, i.e. the corner side plate 501, includes a first segment 26 extending along the first direction X and a second segment 27 extending along the second direction Y, where the first direction X intersects the second direction Y; the figure illustrates this by taking the first direction X and the second direction Y as being perpendicular. In the second direction Y, the distance between the end of the second sub-segment 27 away from the first sub-segment 26 and the first sub-segment 26 is the first distance L1; in the first direction X, the distance between the end of the first sub-segment 26 away from the second sub-segment 27 and the second sub-segment 27 is the second distance L2. The sum of the first distance L1 and the second distance L2 is greater than or equal to 1 millimeter.

[0059] It should be noted that the larger the size of the first opening, the weaker the strength of the backplate in that area.

[0060] The display module provided in this application embodiment has a first distance L1 and a second distance L2 greater than or equal to 1 mm. This reduces the manufacturing difficulty of the first opening and decreases its size, thereby improving the support strength of the back panel.

[0061] In some embodiments, the first distance L1 is equal to the second distance L2.

[0062] In some embodiments, the connecting sub-side plate includes: a first connecting sub-side plate and a second connecting sub-side plate disposed opposite to each other, and a third connecting sub-side plate and a fourth connecting sub-side plate disposed opposite to each other and connected to the first connecting sub-side plate and the second connecting sub-side plate; the light source assembly is located between the light guide plate and the first connecting sub-side plate; the first direction X is the extension direction of the first connecting sub-side plate and the second connecting sub-side plate; the second direction Y is the extension direction of the third connecting sub-side plate and the fourth connecting sub-side plate.

[0063] In some embodiments, such as Figure 12 As shown, extending into two first sub-side plates 503 in the same corner area 7, the first portion 19 of one first sub-side plate 503 is parallel to the first direction X, and the first portion 19 of the other first sub-side plate 503 is parallel to the second direction Y; the length of the first portion 19 parallel to the second direction Y in the second direction Y is a first length L3, and the length of the first portion 19 parallel to the first direction X in the first direction X is a second length L4; the first length L3 is less than or equal to a first distance (not shown) corresponding to its adjacent corner sub-side plate 501, and the second length L4 is less than or equal to a second distance (not shown) corresponding to its adjacent corner sub-side plate 501.

[0064] In some embodiments, the first length L4 is equal to the second length L3.

[0065] In some embodiments, L1, L2, L3, and L4 are all 1 millimeter.

[0066] In some embodiments, such as Figure 11 As shown, in the direction perpendicular to the base plate 4, the length of the first sub-side plate 503 is less than the length of the connecting sub-side plate 502 to which it is connected.

[0067] In some embodiments, such as Figure 13 As shown, the edge of the first part 19 includes a rounded corner area Q2; The bottom of the second opening 1901 is curved.

[0068] This can prevent defects such as tearing and deformation of the first part, and improve the yield rate of backplate manufacturing.

[0069] In some embodiments, the radius of the rounded corner area Q2 is 0.3 mm; the radius of the arcuate bottom of the second opening is 0.3 mm.

[0073] In some embodiments, the opposing substrate is located on the side of the array substrate facing the second polarizer.
