Description

Technical Field

[0001] This invention relates to the field of display technology, and particularly to an OLED display device, a method for manufacturing an OLED display device, and an in-vehicle center console. Background Technology

[0002] With the rapid development of OLED (Organic Electro-Laser Display or Organic Light Emitting Diode) display technology, OLED technology has gradually been applied in the passenger vehicle sector. The LCD screens currently widely used in passenger vehicles are gradually being replaced by OLED screens, which offer better display effects and higher space utilization.

[0003] Currently, OLED screens used in passenger vehicles generally employ two mounting methods: one is to assemble the OLED display module into a housing of the display assembly, with the housing surrounding the circumferential sides of the OLED display module for support; the other is to fix the back panel of the OLED display module to a metal frame using adhesive or other methods to form a display assembly, with the frame surrounding the circumferential sides of the OLED display module for support, and then assembling the display assembly onto the dashboard frame or the center console screen of the cross-car beam (CCB). In both of these methods, the metal frame or housing occupies a portion of the bezel width, hindering the creation of narrow bezels, thus requiring further improvement in display quality and aesthetics. Summary of the Invention

[0018] In one embodiment, the housing includes a first chamber for accommodating the first flexible circuit board and the first circuit board, and a first fastener is provided on the housing, the first flexible circuit board and the first fixing post passing through the housing, the first flexible circuit board and the first fixing post in sequence to fix the housing, the first flexible circuit board and the base together.

[0019] In one embodiment, a recess is provided in the first chamber, and the first circuit board covers the recess.

[0020] In one embodiment, the housing further includes a second chamber for accommodating a second circuit board connected to the first circuit board;

[0021] The depth of the second chamber is greater than the depth of the first chamber, such that the distance between the second circuit board and the base is greater than the distance between the first circuit board and the base.

[0022] In one embodiment, the OLED display module includes an optically transparent adhesive layer, a polarizer, and an OLED display panel arranged sequentially.

[0023] The optically transparent adhesive layer is connected to the side of the glass cover plate facing the OLED display module, and the OLED display panel is connected to the base through an adhesive layer.

[0024] According to a second aspect of the present invention, the present invention provides a method for manufacturing an OLED display device, comprising the following steps:

[0025] A support section is formed on the base to obtain a backplate with an integrated structure;

[0026] Connect the OLED display module to the base;

[0027] The support portion is brought into contact with and connected to the side of the glass cover plate facing the OLED display module.

[0028] In one embodiment, after forming a support portion on the base to obtain a backplate with an integral structure, the following steps are further included:

[0029] At least two grooves extending in a first direction are formed on the base at a location corresponding to the bending area of ​​the first flexible circuit board;

[0030] The first flexible circuit board and the first circuit board connected to the first flexible circuit board are passed through the corresponding grooves in sequence, and the bending area of ​​the first flexible circuit board is fixed in the corresponding groove.

[0031] In one embodiment, before the support portion contacts and connects with the side of the glass cover plate facing the OLED display module, the following step is further included:

[0032] The two sides of the OLED display panel are connected to an optically transparent adhesive layer and a polarizer, respectively, to obtain an OLED display module;

[0033] The OLED display panel is connected to the first circuit board via the first flexible circuit board;

[0075] The invention will now be further described with reference to the accompanying drawings.

[0076] like Figure 1A As shown, in existing OLED display devices, the OLED display module 102 has a metal backplate 101 on its back side, a glass cover 103 on its front side, and a housing 104 covering the OLED display module 102. The housing 104 surrounds the circumferential sides of the OLED display module 102 to provide support. Figure 1B As shown, in another existing OLED display device, the metal backplate 101 of the OLED display module 102 is fixed to the metal frame 105 by means of adhesive or other methods to form a display assembly. The metal frame 105 surrounds the circumferential sides of the OLED display module 102 to provide support, and the display assembly is mounted on the dashboard assembly frame or the center console screen of the cross car beam (CCB). In the OLED screens formed by the above two methods, both the metal frame and the casing occupy a portion of the width of the OLED display module 102's bezel, which is not conducive to the formation of a narrow bezel, thus resulting in slightly inferior display and appearance effects.

[0077] like Figures 3-12 As shown, according to a first aspect of the present invention, the present invention provides an OLED display device 100, which can be applied to automotive screens (such as...). Figure 3 (as shown), or display devices in other fields.

[0078] Specifically, the OLED display device 100 of the present invention includes a backplate (BKT, Bracket) 1, an OLED display module 2, and a glass cover plate (CG, Cover Glass) 3 located on one side of the OLED display module 2.

[0079] The backplate 1 includes an integrally formed base 11 and a support 12. The base 11 is used to connect to the OLED display module 2, and the support 12 extends on the base 11 in a direction toward the glass cover 3. Therefore, a space for accommodating the OLED display module 2 is formed between the support 12, the base 11, and the glass cover 3, and the OLED display module 2 can be fixed on the base 11.

[0080] like Figure 3 , Figure 4 and Figure 5 As shown, the support portion 12 only contacts and connects to the side of the glass cover plate 3 facing the OLED display module 2 (e.g., the bottom side), thus serving to support the glass cover plate 3. Since the support portion 12 is only connected to the bottom side of the glass cover plate 3 and does not cover the circumferential side of the glass cover plate 3, the entire bezel of the OLED display module 2 is composed of the glass cover plate 3. This reduces the width of the bezel occupied by the metal frame or casing in the prior art, which is beneficial to achieving the overall narrow bezel visual effect of the OLED display device 100.

[0081] Furthermore, since the supporting function is achieved through the support portion 12 integrally formed on the base 11, the metal frame 105 in the prior art can be eliminated (e.g., Figure 1B As shown in the figure, the OLED display device 100 of the present invention has fewer parts due to its structure, which is beneficial to improving assembly efficiency.

[0082] The base 11 and support 12 of this aspect will be described in detail below. It should be understood that the embodiments described below are merely exemplary and are not intended to limit the base 11 and support 12 of the present invention.

[0083] Please refer to Figure 4 , Figure 5 And please combine Figure 9 and Figure 10 The support portion 12 is provided at the circumferential edge of the base portion 11 and smoothly transitions to the circumferential edge of the base portion 11. For example, the curvature between the outer contour line of the support portion 12 and the outer contour line of the base portion 11 is continuous (G2 continuous) to avoid forming sharp corners and creating stress concentration areas.

[0084] like Figure 10 As shown, the thickness d1 of the support portion 12 is different from that of the base portion 11. For example, the thickness (or width) of the support portion 12 is greater than the thickness d1 of the base portion 11. Figure 10As shown, the dimension of the end of the support portion 12 is d2, and the thickness at the connection between the support portion 12 and the base portion 11 is still d1, so d2 > d1. Since the support portion 12 plays a major supporting role, setting the thickness of the support portion 12 to be relatively large can ensure its supporting strength.

[0085] Furthermore, the thickness of each part of the support portion 12 can be set to be 0%-30% greater than the thickness d1 of the base portion 11. For example, when the thickness d1 of the base portion 11 is 2mm, the maximum thickness of the support portion 12 can be 2.6mm.

[0086] In a specific implementation, the support portion 12 can be constructed as an arc-shaped structure that curves upward from the circumferential edge of the base 11 in a manner with a variable radius. Therefore, the support portion 12 can be constructed as a curved surface structure with different radii of curvature. For example, the radius of curvature of the support portion 12 is larger near its end and smaller near the point where it connects to the base 11, resulting in a larger size at the end of the support portion 12.

[0087] Optionally, the outer contour line of the support portion 12 may include multiple curves. For example, the support portion 12 may include multiple curves with a radius of curvature in the range of 3mm-30mm, and the multiple curves are smoothly connected to each other, so that the overall shape of the support portion 12 is smoother and more beautiful.

[0088] Optionally, the outer contour of the support portion 12 may also include multiple connected straight lines and curves, wherein the straight lines and curves are tangent to each other.

[0089] Furthermore, the support portion 12 extends upward on the base 11 at a certain angle. The angle between the support portion 12 and the base 11 can be between 90° and 135°, so that the support portion 12 has sufficient strength to support the glass cover plate 3 and ensures that the distance between the glass cover plate 3 and the base 11 is within a suitable range to form a space sufficient to accommodate the OLED display module 2. For example, the support portion 12 can be configured such that the distance between the glass cover plate 3 and the base 11 is within the range of 0.5mm-3mm.

[0090] A first attachment element 15 is provided between the support part 12 and the glass cover plate 3. The first attachment element 15 is used to fix the connection area of ​​the support part 12 to one side of the glass cover plate 3. The width of the connection area of ​​the support part 12 is not less than 1 mm, because if the width of the connection area of ​​the support part 12 is less than 1 mm, the risk of connection failure between it and the glass cover plate 3 is high.

[0091] Furthermore, the width of the connection area of ​​the support portion 12 should not be too large, preferably not exceeding the dimension d2 of the end of the support portion 12. Since the connection area of ​​the support portion 12 is connected to the glass cover plate 3 via the first attachment element 15, and the first attachment element 15 has adhesiveness and compressibility (with a deformation of approximately 0.1 mm), after connecting the connection area of ​​the support portion 12 to the glass cover plate 3, the first attachment element 15 may be compressed beyond the range of the connection area of ​​the support portion 12. Therefore, the width of the connection area needs to be set smaller than the dimension d2 of the end of the support portion 12 to prevent the first attachment element 15 from being pressed outside the end face of the support portion 12. Thus, an excessively large width of the connection area of ​​the support portion 12 will affect the width of the bezel of the OLED display module 2, and thus affect the appearance and display effect.

[0092] Generally, the thickness of the base 11 is ≥2mm, therefore the width of the connection area of ​​the support 12 is preferably ≥2mm.

[0093] The first attachment element 15 may be, for example, a foam adhesive or other adhesive that can perform an adhesive function.

[0094] like Figure 5 As shown, the OLED display module 2 is connected to the first circuit board (PCB) 6 via a first flexible circuit board (e.g., a flexible circuit board with a chip bonded to it) 5. A groove 13 extending in a first direction is provided on the base 11 at a position corresponding to the bending area of ​​the first flexible circuit board 5. Since the support portion 12 and the base 11 form a space to accommodate the OLED display module 2, the first flexible circuit board 5 connected to the OLED display module 2 and the first circuit board 6 connected to the first flexible circuit board 5 need to pass through the base 11 from the upper side to reach the back side of the OLED display module 2. Therefore, by slotting the base 11, the first flexible circuit board 5 and the first circuit board 6 can pass through the base 11 to facilitate the fixation of the first circuit board 6.

[0095] Since some heat-generating components are integrated on the first circuit board 6, by passing the first circuit board 6 through the slot 13 and installing it on the back of the OLED display module 2, the aforementioned high-heat-generating components can be kept away from the OLED display module 2, thereby reducing the screen temperature rise and improving the overall performance.

[0096] Furthermore, the groove 13 is configured to allow the connected first flexible circuit board 5 and first circuit board 6 to pass through it. However, if the groove 13 is too large, it will affect the overall strength of the base 11. Therefore, the number of grooves 13 can be set to at least two, and the at least two grooves 13 are spaced apart in the first direction. Understandably, two first circuit boards 6 are also set accordingly, which pass through the corresponding grooves 13 and are then connected by the second flexible circuit board 8 (e.g., Figure 8 (As shown).

[0097] The above solution is particularly suitable for applications of in-vehicle display devices, because in-vehicle display devices are usually large in size, so the above solution has good applicability.

[0098] The first direction can be, for example, the width direction of the base 11.

[0099] Please continue to refer to this. Figure 5 Each groove 13 is provided with a second attachment element 16, which is used to fix the bending area 51 of the first flexible circuit board 5 in the corresponding groove 13. The second attachment element 16 not only fixes the bending area 51 of the first flexible circuit board, but also protects and cushions it to prevent damage to the bending area 51 of the first flexible circuit board.

[0100] The second attachment element 16 may be the same as the first attachment element 15; for example, the second attachment element 16 may also be foam adhesive. Understandably, the second attachment element 16 may be different from the first attachment element 15, and may use other adhesives.

[0101] like Figure 9 As shown, the distance between the edge of the groove 13 and the base 11 is not less than 3mm to ensure that the base 11 has sufficient strength.

[0102] In some preferred embodiments, the base 11 is made of a metallic material (e.g., aluminum alloy or stainless steel), and a support portion 12 is formed on the base 11 by stamping, thereby obtaining a one-piece back plate 1 and achieving the curved structure of the support portion 12 and the effect of varying wall thickness between it and the base 11. Figure 10 As shown, a first fixing post 14 and a second fixing post 17 are provided on the side of the base 11 opposite to the support part 12. The first fixing post 14 is used to fix and connect to the first circuit board 6 (e.g., Figure 5 As shown), the second fixing post 17 is used to connect to the housing 4 described below (as shown). Figure 7 (As shown).

[0103] The first fixing post 14 and the second fixing post 17 can be fixed to the back side of the base 11 by means of riveting, welding, bonding, etc.

[0104] Please continue to refer to this. Figure 4 , Figure 5 , Figure 6 and Figure 7 The OLED display device 100 of the present invention further includes a housing 4, which is disposed on the side of the base 11 away from the glass cover plate 3 (i.e., the back side of the base 11). Figure 5As shown, the support portion 12 is at least partially disposed on the outer side of the housing 4. For example, the support portion 12 can be completely exposed on the outer side of the housing 4, meaning that the overall dimensions of the housing 4 in both the width and length directions can be smaller than the overall dimensions of the back plate 1. Figure 10 As shown, the support portion 12 is exposed on the outside of the housing 4, thus making it a visible area that can be observed from the outside, while the base portion 11 is not visible because it is covered by the housing 4.

[0105] Because in this invention, the support portion 12, which is directly connected to the back plate 1 of the OLED display module 2, supports the glass cover plate 3, without the need for a housing 4 or a frame structure as in the prior art, the support portion 12 can be exposed outside the housing 4 (i.e., without the housing 4 supporting the glass cover plate 3, the support portion 12 can directly serve as the exterior surface, such as...). Figure 10 As shown), this allows the overall size of the housing 4 to be smaller than the overall size of the back panel 1, thus enabling the OLED display device 100 to be installed on the vehicle's center console, and viewed from the front inside the vehicle (e.g., Figure 2 As shown, the bezel of the OLED display device 100 is entirely composed of a glass cover plate 3, thus the OLED display device 100 can present a better overall appearance and floating screen effect.

[0106] Furthermore, since the support portion 12 is exposed outside the housing 4, the exposed support portion 12 can also serve as a heat exchange part, directing the heat from the heating elements integrated on the first circuit board 6 and the second circuit board 7 to the external environment, thereby reducing the temperature of the OLED display device 100.

[0107] Specifically, please refer to Figure 3 , Figure 11 and Figure 12 The housing 4 includes a first chamber 41 for accommodating the first flexible circuit board 5 and the first circuit board 6. A first fastener 44 is provided on the housing 4. The first fastener 44 passes through the housing 4, the first flexible circuit board 5 and the first fixing post 14 in sequence to fix the housing 4, the first flexible circuit board 5 and the base 11 together.

[0108] Furthermore, such as Figure 3 As shown, a recess 43 is provided in the first chamber 41, and the first circuit board 6 covers the recess 43, so that there is a certain distance between the first circuit board 6 and the bottom of the first chamber 41, which is conducive to the heat dissipation of the first circuit board 6.

[0109] like Figure 3 and Figure 12As shown, the housing 4 also includes a second chamber 42, which is used to accommodate a second circuit board 7 connected to the first circuit board 6. The depth h2 of the second chamber 42 is greater than the depth h11 of the first chamber 41 (and also greater than the depth h12 of the recess 43), making the distance between the second circuit board 7 and the OLED display module 2 greater than the distance between the first circuit board 6 and the OLED display module 2; that is, the second circuit board 7 is further away from the OLED display module 2. Since the second circuit board 7 integrates some high-heat-generating components, by placing the second circuit board 7 on the back of the OLED display module 2 and further away from it, the aforementioned high-heat-generating components can be kept away from the OLED display module 2, thereby reducing screen temperature rise and improving the overall user experience.

[0110] Therefore, it is understandable that h2 > h12 > h11.

[0111] like Figure 7 and Figure 12 As shown, the housing 4 has a first hole 441 near the left side, which is used to connect with the first fastener 44; the housing 4 also has a second hole 451 near the right side, which is used to connect with the second fastener 45. The second fastener 45 passes through the second hole 451 of the housing 4 and the second fixing post 17 on the back side of the base 11 in sequence to connect the housing 4 to the base 11.

[0112] Therefore, as Figure 12 As shown, the visible areas are the left side of the housing 4 and the first hole 441, the two first holes 441, the first hole 441 and the second hole 451, and the second hole 451 and the right side of the housing 4.

[0113] like Figure 6 As shown, the second circuit board 7 can be fixedly connected to the housing 4 via the third fastener 46. After the second circuit board 7 is fixed, it can be connected to the corresponding first circuit board 6 via the second flexible circuit board 8, as shown. Figure 8 As shown.

[0114] The second circuit board 7 can be mounted upright, while the connection between the housing 4 and the first circuit board 6 and the base 11 can be mounted from the back.

[0115] Among them, the first fastener 44, the second fastener 45 and the third fastener 46 can be bolts, screws, rivets, etc.

[0116] The housing 4 is made of plastic, and its shape can be irregular and customizable as needed. For example, at the bending area 51 corresponding to the first flexible circuit board 5, its internal space can be appropriately increased to avoid contact with the bending area 51 of the first flexible circuit board 5 during installation (see [link]). Figure 5 (As shown).

[0117] Please continue to refer to this. Figure 5 The OLED display module 2 includes an optically clear adhesive (OCA) layer 21, a polarizer (POL) 22, an OLED display panel 23, and an adhesive layer 24, which are sequentially arranged. The OCA layer 21 is connected to one side of the glass cover plate 3, and the OLED display panel 23 is connected to the base 11 through the adhesive layer 24, thereby fixing the OLED display module 2 between the glass cover plate 3 and the base 11.

[0118] The adhesive layer 24 may be, for example, a double-sided adhesive with thermal conductivity, which may be made of a pressure-sensitive adhesive (PSA).

[0119] According to a second aspect of the present invention, the present invention provides a method for manufacturing an OLED display device, comprising the following steps.

[0120] Step a: Form a support portion 12 on the base 11 to obtain a back plate 1 with an integral structure. The support portion 12 can be formed on the base 11 by stamping as described above, thereby obtaining a back plate 1 with an integral structure.

[0121] Step b: At least two grooves 13 extending in the first direction are formed on the base 11 at the location corresponding to the bending area 51 of the first flexible circuit board 5.

[0122] Step c: Pass the first flexible circuit board 5 and the first circuit board 6 connected to the first flexible circuit board 5 through the groove 13, and fix the bending area 51 of the first flexible circuit board 5 in the groove 13. For example, the second attachment element 16 described above can be used to fix the bending area 51.
