Description
Technical Field
[0001] This utility model relates to the field of AMOLED display technology, and in particular to a camera integrated structure on an FPC board within an AMOLED display. Background Technology
[0002] AMOLED (Active Matrix Organic Light Emitting Diode) is a display technology. OLED (Organic Light Emitting Diode) describes a specific type of thin-film display technology: organic electroluminescent display; AM (Active Matrix) refers to the underlying pixel addressing technology.
[0003] Currently, cost competitiveness is becoming increasingly important in the wearable electronics industry, such as... Figure 8 and Figure 9 As shown, many watches come with cameras, but traditional designs install the camera independently on the mainboard. The main screen 1-1 and FPC 1-2 are set independently from the camera, resulting in a large space occupation and cost inside the module. To address this, a camera integrated structure within the FPC board of an AMOLED display is proposed. Utility Model Content
[0004] Therefore, it is necessary to provide a camera integrated structure on an FPC board within an AMOLED display to address the aforementioned technical issues. This structure integrates a conventional camera module onto the FPC and connects it to the main control board via the FPC, thus saving space within the module.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] An AMOLED display FPC board integrated camera structure includes an AMOLED main screen and a camera through hole formed on the surface of the AMOLED main screen. A main FPC board is bonded to the bottom of the AMOLED main screen, and the main FPC board has a bonding end at the end away from the AMOLED main screen.
[0007] The main FPC board is connected to a secondary FPC for communication with the main control board via a bonding end. The secondary FPC is equipped with a camera module, and the main FPC board is bent on the back of the AMOLED main screen so that the camera module corresponds to the camera through hole.
[0008] Furthermore, one side of the sub-FPC has a camera mounting area, and the camera module is mounted on the camera mounting area.
[0009] Furthermore, a front reinforcing plate that is fixed to the sub-FPC is fitted around the periphery of the camera mounting area.
[0010] Furthermore, a back reinforcement plate is fixed on the other side of the sub-FPC at the location corresponding to the camera mounting area, and the edge of the back reinforcement plate coincides with the edge of the front reinforcement plate.
[0011] Furthermore, a metal heat dissipation layer is attached to the outer side of the back reinforcement plate.
[0012] Furthermore, through slots are provided at the four corners of the sub-FPC corresponding to the front reinforcing plate;
[0013] The front reinforcing plate, the back reinforcing plate, and the metal heat dissipation layer all have connecting slots at the positions corresponding to the through slots, and the connecting slots and through slots can connect the front and back sides of the sub-FPC.
[0014] Furthermore, a heat dissipation groove is formed at the center of the metal heat dissipation layer.
[0015] Furthermore, the AMOLED main screen has an upper glass and a lower glass that are bonded together, and an upper polarizer and a lower polarizer are respectively bonded to the outer side of the upper glass and the lower glass.
[0016] The outer side of the upper polarizer is covered with a cover plate by optical adhesive, and the main FPC board is bound to the lower glass.
[0017] Furthermore, a light-shielding foam is attached to the outer side of the lower polarizer, and a copper foil is attached to the surface of the light-shielding foam.
[0018] Furthermore, the camera through-hole sequentially passes through the upper polarizer, upper glass, lower glass, lower polarizer, light-shielding foam, and copper foil, connecting the inner and outer sides of the AMOLED main screen for the assembly application of the camera module.
[0019] Compared with the prior art, the present invention has the following beneficial effects:
[0020] The camera integrated structure in the FPC board of the AMOLED display provided by this utility model integrates the camera module on the secondary FPC connected to the AMOLED main screen and designs the position to correspond with the camera through hole. In this way, after the main FPC board and the secondary FPC are bent, the camera module can be aligned with the camera through hole, realizing integration and achieving the camera function effect at the same time, without the need for an additional independent camera module connection on the motherboard, which is beneficial to saving internal space of the module and reducing costs.
[0021] By combining the front and rear reinforcing plates, the area where the camera module is assembled can be rigidly supported, which can ensure that the camera module will not be misaligned due to the softness of the sub FPC during application.
[0022] At the same time, the design of the through slot and connecting slot can connect the inside and outside of the sub FPC, realize the exchange of gas on both sides, promote the flow of internal air, and reduce the ambient temperature around the camera module when it is in use.
[0023] The design of heat sinks and metal heat dissipation layers allows heat to be transferred through the back reinforcement plate, and the metal heat dissipation layer further disperses the heat, increasing the effective heat dissipation area and achieving effective heat dissipation in the camera mounting area on the secondary FPC, thus ensuring the stable operation of the camera module.

[0038] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0039] As described in the background art, such as Figure 8 and Figure 9 As shown, many watches come with cameras, but traditional designs install the camera independently on the mainboard. The main screen 1-1 and FPC1-2 are set up independently from the camera, resulting in a large space occupation and cost inside the module.
[0040] To address this technical problem, this invention provides a camera integrated structure on an FPC board within an AMOLED display, which is applied to AMOLED displays.
[0041] For details, please refer to Figures 1-9 The camera integrated structure of the FPC board in the AMOLED display specifically includes an AMOLED main screen 1 and a camera through hole 2 formed on the surface of the AMOLED main screen 1. The bottom of the AMOLED main screen 1 is bonded to a main FPC board 3, and the end of the main FPC board 3 away from the AMOLED main screen 1 has a bonding end 31.
[0042] The main FPC board 3 is connected to a secondary FPC 4 for communication with the main control board via a binding end 31. The secondary FPC 4 is equipped with a camera module 41. After the main FPC board 3 is bent on the back of the AMOLED main screen 1, the camera module 41 corresponds to the camera through hole 2.
[0043] The camera integrated structure in the FPC board of the AMOLED display provided by this utility model integrates the camera module 41 on the secondary FPC4 connected to the AMOLED main screen 1, and designs the position to correspond with the camera through hole 2. In this way, after the main FPC board 3 and the secondary FPC4 are bent, the camera module 41 can be aligned with the camera through hole 2, realizing integrated integration while achieving the camera function effect, without the need for an additional independent camera module connection on the motherboard, which is beneficial for saving internal space of the module and reducing costs.
[0044] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0045] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0046] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0047] Example 1
[0048] Please refer to Figures 1-5 An AMOLED display screen with an integrated camera structure on an FPC board includes an AMOLED main screen 1 and a camera through-hole 2 formed on the surface of the AMOLED main screen 1. A main FPC board 3 is bonded to the bottom of the AMOLED main screen 1, and the main FPC board 3 has a bonding end 31 at the end away from the AMOLED main screen 1.
[0049] The main FPC board 3 is connected to a secondary FPC 4 for communication with the main control board via a binding end 31. The secondary FPC 4 is equipped with a camera module 41. After the main FPC board 3 is bent on the back of the AMOLED main screen 1, the camera module 41 corresponds to the camera through hole 2.
[0050] In this embodiment, the AMOLED main screen 1 and the camera module 41 are connected to the main control board through the main FPC board 3 and the secondary FPC 4. Therefore, the ribbon cable of the camera module 41 in the secondary FPC 4 will avoid the ribbon cable of the main FPC board 3. In this way, when the secondary FPC 4 is connected to the main FPC board 3, the connected pins can be connected to both the main FPC board 3 and the camera module 41.
[0051] The sub-FPC4 has a camera mounting area 42 on one side, and the camera module 41 is mounted on the camera mounting area 42.
[0052] In this embodiment, the camera, which is typically found in AMOLED modules, is integrated onto the secondary FPC4 and corresponds to the camera mounting area 42. This allows the main FPC board 3 and the secondary FPC4 to be bent and flipped, as shown below. Figure 4 As shown, the camera module 41 can be designed to correspond with the camera through hole 2, and the secondary FPC 4 can be connected to the main control board, so as to realize the synchronous connection between the main control board, the AMOLED main screen 1 and the camera module 41. This eliminates the need for additional connection of the camera FPC and camera design on the main control board, which is conducive to saving the overall internal space of the module, improving the utilization rate of internal space and optimizing production costs.
[0053] like Figure 4 As shown, after the secondary FPC4 is flipped and assembled with the corresponding camera through-hole 2, the right edge of the secondary FPC4 can be fixed to the housing or main control board to ensure the stability of the secondary FPC4 application. In this embodiment, the AMOLED main screen 1 and the secondary FPC4 are not fully bonded. In actual application, they can be fully bonded so that the camera module 41 is inserted into the corresponding camera through-hole 2. The left side of the secondary FPC4 can be glued and fixed to the AMOLED main screen 1 by double-sided adhesive or other fixing methods.
[0054] Example 2
[0055] The camera integration structure within the FPC board of the AMOLED display provided in Embodiment 1 is further optimized, specifically, as follows: Figure 5 As shown, a front reinforcing plate 43, which is fixed to the sub-FPC4, is sleeved around the periphery of the camera mounting area 42.
[0056] A back reinforcement plate 44 is fixed on the other side of the sub-FPC4 at the position corresponding to the camera mounting area 42, and the edge of the back reinforcement plate 44 coincides with the outer edge of the front reinforcement plate 43.
[0057] Through the cooperation of the front reinforcing plate 43 and the back reinforcing plate 44, a rigid support can be formed in the camera mounting area 42. This ensures the stability of the camera module 41 after it is installed on it, and the application of the camera module 41 will not be hindered by the relatively soft sub-FPC4.
[0058] The back reinforcement plate 44 in this embodiment can be made of metal, such as aluminum or copper. For example, when copper sheets are used for support, the heat generated in the camera mounting area 42 can be transferred.
[0059] A metal heat dissipation layer 45 is attached to the outer side of the back reinforcement plate 44. The heat transferred by the back reinforcement plate 44 will be further transferred to the surface of the metal heat dissipation layer 45 for effective heat dissipation, so as to reduce the ambient temperature in the camera mounting area 42 during operation.
[0060] Example 3
[0061] The camera integration structure within the FPC board of the AMOLED display provided in Embodiment 1 or 2 is further optimized, such as... Figure 5 , Figure 6 and Figure 7 As shown, through slots 46 are provided at the four corners of the sub-FPC4 corresponding to the front reinforcing plate 43. The front reinforcing plate 43, the back reinforcing plate 44 and the metal heat dissipation layer 45 are all provided with connecting slots 47 at the positions corresponding to the through slots 46. The connecting slots 47 and the through slots 46 can make the front and back sides of the sub-FPC4 connected.
[0062] A heat dissipation groove 48 is provided at the center of the metal heat dissipation layer 45;
[0063] The design of the through slot 46 and the connecting slot 47 can promote airflow on both sides of the sub-FPC4, allowing them to interact. This airflow can remove the high ambient temperature around the camera module mounting area 42, and together with the back reinforcement plate 44 and the metal heat dissipation layer 45, it can transfer and absorb the local temperature of the sub-FPC4. The heat dissipation slot 48 increases the effective heat dissipation area, further improving the heat dissipation efficiency of the camera module 41.
[0064] Example 4
[0065] The camera integration structure within the FPC board of the AMOLED display provided in Embodiment 3 is further optimized, such as... Figure 4 As shown, the AMOLED main screen 1 has an upper glass 11 and a lower glass 12 that are bonded together, and an upper polarizer 13 and a lower polarizer 14 are respectively bonded to the outer sides of the upper glass 11 and the lower glass 12.
[0066] The outer side of the upper polarizer 13 is attached to a cover plate 15 by optical adhesive, and the main FPC board 3 is bound to the lower glass 12;
[0067] The outer side of the lower polarizer 14 is covered with light-shielding foam 16, and the surface of the light-shielding foam 16 is covered with copper foil 17.
[0068] The camera through-hole 2 passes through the upper polarizer 13, upper glass 11, lower glass 12, lower polarizer 14, light-shielding foam 16 and copper foil 17 in sequence, so that the inner and outer sides of the AMOLED main screen 1 are connected for the assembly application of the camera module 41.
