Detailed Implementation
[0019] The technical solutions in some embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments provided in this application are within the scope of protection of this application.
[0020] Unless the context otherwise requires, throughout the specification and claims, the term "comprising" is interpreted as open and encompassing, that is, "including, but not limited to".
[0021] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this application, unless otherwise stated, "a plurality of" means two or more.
[0022] In describing some embodiments, the term "connection" and its derivative expressions may be used. The term "connection" should be interpreted broadly; for example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium. For example, in describing some embodiments, the term "connection" may be used to indicate that two or more components have direct physical or electrical contact with each other.
[0023] In addition, the use of "based on" implies openness and inclusivity, because processes, steps, calculations or other actions "based on" one or more conditions or values can in practice be based on additional conditions or values beyond those conditions.
[0024] It should be understood that when a layer or element is referred to as being on another layer or substrate, it can mean that the layer or element is directly on the other layer or substrate, or that there is an intermediate layer between the layer or element and the other layer or substrate.
[0025] This document describes exemplary embodiments with reference to cross-sectional views, which are intended as idealized exemplary drawings. In the drawings, the thickness of the layers and the area of the regions are enlarged for clarity. Therefore, variations in shape relative to the drawings are contemplated due to, for example, manufacturing techniques and / or tolerances. Thus, exemplary embodiments should not be construed as limited to the shapes of the regions shown herein, but rather include shape deviations caused, for example, by manufacturing processes. For example, etched areas shown as rectangular would typically have curved features. Therefore, the regions shown in the drawings are schematic in nature, and their shapes are not intended to show the actual shapes of the areas of the device, nor are they intended to limit the scope of the exemplary embodiments.
[0026] In related technologies, "pre-attachment followed by assembly" automotive modules first attach the display panel to the cover plate and then assemble it with the light strip. Two structural points are most prone to light leakage, where moisture or dust can enter and cause internal module defects. The first point is the bend in the flexible circuit board. To accommodate the bending of the flexible circuit board during assembly, the back plate typically has a notch at the bend position to accommodate this. This is a standard assembly design. After the light strip is assembled, a gap exists between the bend in the flexible circuit board and the cover plate due to the notch. Although conductive tape is applied to the surface of the flexible circuit board to partially cover this gap, a certain amount of light still remains between the conductive tape and the cover plate. The light from the light strip escapes through this gap under the cover plate, causing light leakage defects in the module.
[0027] For some display modules used in near-shore or offshore applications, in addition to dustproofing, waterproofing, and light leakage prevention, it is also necessary to prevent salt spray from seeping into the display module through the bends of the flexible circuit board. Currently, due to appearance or special structural design, some products in the automotive market cannot completely seal the bends of the flexible circuit board at the overall unit level. Therefore, in the module state, the requirements for waterproofing and salt spray prevention at the bends of the flexible circuit board are relatively high. For such module products, salt spray may seep into the module through the gaps between the die-cast retaining wall and the flexible circuit board, or between the flexible circuit board and the cover plate, along with moisture through conductive tape. After entering the display module, salt spray tends to accumulate in large amounts in the IC (Integrated Circuit) area, causing corrosion to the display circuitry and leading to display abnormalities.
[0028] Based on the above problems, this application proposes a display module, such as... Figure 1 As shown, the display module 10 includes a backlight module 11, a display panel 12, a flexible circuit board 13, a cover plate 14, and a conductive tape 15.
[0029] like Figure 1 As shown, the backlight module 11 includes a backplate 110 and a light strip 111. The backplate 110 includes a connected baffle 112 and a base plate 113. The light strip 111 is disposed on the inner side of the baffle 112. The baffle 112 includes at least one notch, such as... Figure 2 The diagram shown is a schematic of a gap in the retaining wall 112.
[0030] The display panel 12 is disposed on the light-emitting side of the backlight module 11. The flexible circuit board 13 is electrically connected to the display panel 12, such as... Figure 1 and Figure 3 As shown, the flexible circuit board 13 bends from the notch in the retaining wall 112 to the side of the base plate 113 away from the display panel 12. For example... Figure 3 As shown, a light strip 111 is provided along the side direction X of the backlight module 11, and a first gap 130 is provided between the flexible circuit board 13 and the barrier wall 112.
[0031] like Figure 4 As shown, the cover plate 14 is disposed on the side of the display panel 12 away from the backlight module 11, and a second gap 131 is formed between the flexible circuit board 13 and the cover plate 14 at the notch of the barrier 112.
[0032] like Figure 3 and Figure 4 As shown, the conductive tape 15 is connected to the base plate 113, the retaining wall 112 and the cover plate 14, and the conductive tape 15 covers the first gap 130 and the second gap 131.
[0033] Based on the above embodiments, a first gap 130 exists between the flexible circuit board 13 and the baffle 112. Moisture, dust, and salt spray can enter the interior of the display module 10 through this gap, affecting the internal circuitry and causing display abnormalities. Similarly, a second gap 131 exists between the flexible circuit board 13 and the cover plate 14, allowing light from the LED strip 111 to leak out, causing display abnormalities. Furthermore, moisture, dust, and salt spray can also enter the interior of the display module 10 through this gap, affecting the operation of the internal circuitry.
[0034] By covering the first gap 130 and the second gap 131 with conductive tape 15, fine particles such as moisture, dust, and salt spray can be prevented from entering the interior of the display module 10 through the first and second gaps, thereby preventing display abnormalities in the display panel 12 and improving the reliability and stability of the display module 10. Covering the second gap 131 with conductive tape 15 also prevents light leakage from the display module 10, which could affect the display effect. Furthermore, the conductive tape 15 is connected to the base plate 113, the baffle 112, and the cover plate 14, ensuring a tighter adhesion between the conductive tape 15 and the display module 10 and guaranteeing the stability of the adhesion.
[0035] In some embodiments, the specific connection between the conductive tape 15 and the display module 10 is described in more detail, such as... Figure 3As shown, the conductive tape 15 includes a conductive portion 1120 covering the notch in the retaining wall 112. A light strip 111 is provided along the side direction X of the backlight module 10. The opposite side boundaries 1121 of the conductive portion 1120 extend beyond the opposite side boundaries 1122 of the notch. Furthermore, as... Figure 4 As shown, the conductive part 1120 of the conductive tape 15 is also connected to the side of the cover plate 14 near the display panel 12.
[0036] For example, the contact width between the conductive tape 15 and the side of the backing plate 110 should extend beyond the opening of the retaining wall by a certain distance to ensure the bonding effect. For reference, this distance should be ≥5mm.
[0037] In the above embodiment, when the opposite side boundaries of the conductive part 1120 exceed the opposite side boundaries of the notch, the conductive part 1120 can cover the notch of the retaining wall 112. Furthermore, the conductive part 1120 is also connected to the cover plate 14. The conductive part 1120 can also cover the second gap 131 between the flexible circuit board 13 and the cover plate 14, which not only avoids the occurrence of light leakage, but also ensures the adhesive strength of the conductive tape 15.
[0038] In some embodiments, such as Figure 5 As shown, a sealing layer 150 is also provided on the conductive tape 15. Specifically, the display module 10 includes a first sealing layer 151, which is located between the conductive tape 15 and the flexible circuit board 13 at the notch of the retaining wall 112, and the first sealing layer 150 is connected to the conductive tape 15. For example, the top of the sealing layer 150 should be a certain distance from the upper edge of the conductive tape 15. For example, the distance between the top of the sealing layer 150 and the upper edge of the conductive tape 15 can be 3mm. Maintaining a certain distance can prevent the sealing layer 150 from sticking to the bottom surface of the cover plate 14, thus avoiding affecting the fixing effect between the conductive tape 15 and the bottom surface of the cover plate 14.
[0039] For example, to ensure the light leakage prevention effect, the color of the sealing layer 150 should preferably be black; if other colors are chosen, slight light transmission may occur. For instance, the sealing layer 150 can be made of PET (Polyethylene terephthalate), which has excellent optical properties such as high transparency, low haze, and good weather resistance. Furthermore, at the gap in the barrier wall 112, the first sealing layer 151 can ensure that it covers the flexible circuit board 13, preventing light leakage.
[0040] Furthermore, the back of the first sealing layer 151 adopts a non-adhesive design, which ensures that the first sealing layer 151 does not stick to the flexible circuit board 13. This ensures that the flexible circuit board 13 can be covered and protected, and protected against dust, water and light leakage without affecting its normal operation.
[0041] In some embodiments, such as Figure 5 As shown, the display module 10 also includes a second sealing layer 152, which is disposed between the conductive tape 15 and the barrier wall 112, and is connected to both the conductive tape 15 and the barrier wall 112. The second sealing layer 152 also covers the first gap. It can be noted that the back of the second sealing layer 152 has an adhesive backing, and the adhesive thickness of the second sealing layer 152 can be selected from 0.03 mm to 0.05 mm.
[0042] In the above embodiments, the second sealing layer 152 is disposed between the conductive tape 15 and the baffle 112, and the back of the second sealing layer 152 adopts an adhesive design. The adhesive design ensures that the second sealing layer 152 is adhered to the baffle 112 and the base plate 113, thus ensuring the adhesion and stability of the sealing layer 150. The design of the sealing layer 150 also ensures that the conductive tape 15 is more firmly adhered to the display module 10. The second sealing layer 151 covers the first gap, which not only improves the waterproof performance but also prevents salt spray from penetrating into the interior of the display module 10 through the gap or the first gap, thereby preventing corrosion of the internal circuitry of the display module 10.
[0043] In some embodiments, such as Figure 5 and Figure 6 As shown, the second sealing layer 152 extends from between the conductive tape 15 and the retaining wall 112 to between the conductive tape 15 and the base plate 113, and the second sealing layer 152 is connected to both the conductive tape 15 and the base plate 113.
[0044] In the above embodiments, the second sealing layer 152 extends from between the conductive tape 15 and the barrier wall 112 to between the conductive tape 15 and the base plate 113, which can ensure the bonding length of the second sealing layer 152 and avoid affecting the anti-salt spray effect due to insufficient bonding length.
[0045] In some embodiments, such as Figure 6 As shown, the second sealing layer 152 also includes a sealing portion 1520 located between the conductive tape 15 and the base plate 113. The sealing portion 1520 is also located between the conductive tape 15 and the flexible circuit board 13, and is connected to both the conductive tape 15 and the flexible circuit board 13. Along the side direction X of the backlight module 11 where the light strip 111 is provided, the sealing portion 1520 has a continuous structure.
[0046] In the above embodiment, the sealing portion 1520 is located between the conductive tape 15 and the base plate 113, ensuring that the sealing portion 1520 covers the base plate 113 in the length direction and extends beyond the opening of the retaining wall 112. Furthermore, the fact that the sealing portion 1520 covers the base plate 113 in the length direction ensures the length and adhesion of the adhesive. The sealing portion 1520 has a continuous structure, ensuring both the adhesive fixation effect and the uniformity of stress on the flexible circuit board 13. If the sealing portion 1520 is disconnected from the adhesive portion of the flexible circuit board 13, light leakage may occur on both sides and the middle portion of the flexible circuit board 13 due to uneven stress caused by the difference in thickness and hardness between the sealing portion 1520 and the conductive tape.
[0047] In some embodiments, to ensure the stability of the adhesive, such as Figure 6 As shown, a pre-break line 1521 is also provided in the part of the sealing part 1520 that is connected to the flexible circuit board 13. When subjected to external force, the pre-break line 1521 will break first, thereby preventing the crack from extending to other areas of the sealing part 1520 and avoiding further damage to the sealing part. This prevents the flexible circuit board 13 from receiving strong external force due to the breakage of the sealing part 1520, thereby reducing the stress impact on the flexible circuit board 13.
[0048] In some embodiments, such as Figure 7 and Figure 8 As shown, the base plate 113 has a through opening 1131. The light strip 111 extends from the side of the base plate 113 near the display panel 110 through the opening 1131 to the side of the base plate 113 away from the display panel 110. The display module 10 also includes an outlet protective adhesive 16, which is disposed at the opening. One side of the outlet protective adhesive 16 is bonded to the base plate 113, and the other side is bonded to the light strip 111.
[0049] In the above embodiments, the outlet protective adhesive 16 has the characteristic of double-sided adhesion, which can fix both the base plate 113 and the outlet protective adhesive 16, and also fix the light strip 111 to the outlet protective adhesive 16. The fixation of the light strip 111 and the base plate 113 can prevent the light strip 111 from arching under force, which would further cause gaps to form between the light strip 111 and the base plate 113, thereby causing light to leak out from the gaps or salt spray, water vapor, and dust to enter from the gaps.
[0050] In some embodiments, such as Figure 8 As shown, a light strip 111 is provided along the side direction X of the backlight module 11, and the opposite side boundaries of the outlet protective adhesive 16 extend beyond the opposite side boundaries of the opening.
[0051] Furthermore, such as Figure 8As shown, the display module 10 also includes a U-shaped adhesive 17, which is disposed on the outer side of the baffle 112 and the base plate 113. At the opening of the base plate 113, the U-shaped adhesive 17 is bonded to the light strip 111. Along the side direction X of the backlight module 11 where the light strip 113 is disposed, the opposite two side boundaries of the outlet protective adhesive 16 are located inside the opposite two side boundaries of the U-shaped adhesive 17, so that the U-shaped adhesive 17 is connected to the outlet protective adhesive 16.
[0052] In the above embodiments, by connecting the U-shaped adhesive 17 with the outlet protective adhesive 16, the bonding effect of the outlet protective adhesive 16 and the U-shaped adhesive 17 can be increased by increasing the bonding area of the outlet protective adhesive 16. Even if the light strip 111 is arched under force, no gap will be generated, which can effectively achieve the effects of waterproofing, dustproofing and light leakage prevention, thereby ensuring the stability and reliability of the display module 10.
[0053] In other embodiments, such as Figure 7 and Figure 9 As shown, the base plate 113 has a through opening 1131. The light strip 111 extends from the side of the base plate 113 near the display panel 12 through the opening 1131 to the side of the base plate 113 away from the display panel 12. The display module 10 also includes an outlet protective adhesive 16, a first protective adhesive 18, and a second protective adhesive 19. The outlet protective adhesive 16 is located at the opening and is bonded to the base plate 113. The first protective adhesive 18 is located on the outer side of the retaining wall 112 and the base plate 113, and is bonded to the light strip 111 at the opening of the base plate 113. The second protective adhesive 19 has a folded structure and is located between the outlet protective adhesive 16 and the light strip 111, and is bonded to both the outlet protective adhesive 16 and the light strip 111.
[0054] In the above embodiments, the bonding between the first protective adhesive 18 and the light strip 111 achieves the effects of preventing light leakage, as well as dustproofing, waterproofing, and light leakage prevention. Based on the folded structure of the second protective adhesive 19, and the bonding between the second protective adhesive 19, the outlet protective adhesive 16, and the light strip 111, not only can the light strip be prevented from arching and creating gaps during use, achieving dustproofing, waterproofing, and light leakage prevention effects, but it can also increase the range of motion of the light strip, providing greater flexibility.
[0055] Secondly, this application provides a display device, such as... Figure 10 As shown, the display device includes a display module 10 and a controller 20, as described above, and the controller 20 and the display module 10 are electrically connected.
[0056] In the aforementioned display device, the conductive tape covering the first and second gaps prevents fine particles such as moisture, dust, and salt spray from entering the display module through these gaps and affecting its internal circuitry, thereby improving the reliability and stability of the display module. Simultaneously, the conductive tape covering the second gap also prevents light leakage from the display module, thus avoiding any impact on the display effect. Furthermore, the conductive tape is connected to the base plate, retaining wall, and cover plate, ensuring a tighter adhesion between the conductive tape and the display module, guaranteeing stable bonding.
[0057] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
