Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, and more particularly to a display panel and an electronic device. Background Technology

[0002] OLED products are widely used in terminal display devices such as mobile phones, watches, laptops, and televisions. In OLED display panels, the traces used to transmit panel display signals are led out from the edge of the panel and converge at the edge near the driver IC, and then electrically connected to the driver IC to realize signal transmission.

[0003] Most existing OLED display products place the driver IC at the bottom, near the display direction. As a result, due to the large number of traces that need to be bent and connected to the driver IC inside the device, the bottom bezel of the product is relatively wide, which cannot adapt to the trend of narrow bezel design and affects the user experience.

[0038] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0039] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this application pertains.

[0040] The technical solution of this application embodiment is to solve the above-mentioned technical problems, and the general idea is as follows:

[0041] Example 1

[0042] Reference Attachment Figure 1 The display panel provided in this application embodiment includes a substrate 1 and a target circuit board; a display array 3 composed of a plurality of display units (not shown in the figure) is distributed on a first area of ​​a first surface of the substrate 1; a cable (not shown in the figure) corresponding to each display unit is located on a second surface of the substrate 1, the second surface being opposite to the first surface; the target circuit board is electrically connected to the cable located on the second surface of the substrate 1.

[0043] Specifically, in order to solve the problem that the existing technology cannot achieve a narrow bezel design because the wiring occupies a large area in the non-display area, the display panel provided in this embodiment sets the connection end of the cable corresponding to the display unit on the second surface of the substrate 1. The cable can be directly set in the projection area corresponding to the first area, without having to go around the non-display area to the bottom edge of the device and then bend it to the back for electrical connection with the drive controller of the display panel. The width of the bottom edge of the device does not need to reserve space for paralleling and bending of the cable and connector, thereby greatly reducing the width of the bottom edge of the device and achieving a narrow bezel.

[0044] The display panel provided in this embodiment may be, but is not limited to, an OLED panel; see attached drawing. Figure 6 Some display panels have a drive controller ( Figure 6 (Not shown in the image) is positioned at the bottom edge of the corresponding device, and the cables related to the display function need to be installed on the PI substrate 1. ， The upper surface from display area 2 ， Walk to non-display area 3 ， Then wrap it uniformly around the bottom edge along the PI substrate 1 ， The back is electrically connected to the drive controller, therefore a distributor 4 needs to be installed at the bottom edge. ， Connector 5 ， The components also need to accommodate the PI substrate 1 ， The bending area, and thus the PI substrate 1 ， The non-display area at the bottom edge is wider, forming a wider bottom bezel. In this embodiment, a display array 3 is arranged on the first surface of the substrate 1 to form a display area, and cables corresponding to the display array are arranged on the second surface of the substrate 1. For example, holes can be made in the substrate 1 so that the cables can directly pass through the substrate 1 and extend to its second surface, or the cables can extend to the side on the first surface of the substrate 1 and continuously extend to the second surface. Thus, the cables corresponding to the display units can form connection ends dispersedly on the second surface of the substrate 1, and the corresponding splitters (not shown in the figure) and connectors (not shown in the figure), etc., which are set in conjunction with the cables, can be set on the second surface of the substrate 1 without having to bend around to a uniform edge, thereby effectively reducing the width of the bottom bezel of the device.

[0045] The substrate 1 is made of an insulating material, and its surface and interior are capable of routing the cables. In this embodiment, the substrate 1 may be, but is not limited to, a polyimide substrate (PI). Correspondingly, the cables for the display unit may include, but are not limited to, gate lines, source lines, array substrate drive lines (GOA), electrostatic discharge protection circuits (ESD), etc.

[0046] The display unit 31 is at least one of R display unit, G display unit, and B display unit. For example, if all display units 31 are one of R display unit, G display unit, and B display unit, then the display panel is monochrome; if some of the display units 31 are R display units, some are G display units, and the remaining part are B display units, then the display panel is white light display. The above settings are easily understood by those skilled in the art and will not be elaborated further here.

[0047] The target circuit board is a circuit board with wiring functionality, which can be, but is not limited to, a flexible printed circuit (FPC). In this embodiment, the target circuit board does not need to perform display functions, and therefore there is no need to consider the distinction between display and non-display areas. Cables can be arranged at any position, and corresponding splitters and connectors can be set for the cables, greatly improving the flexibility of cable arrangement. In this embodiment, the target circuit board can be directly attached to the second surface of the substrate 1 and electrically connected to the cables. Then, the target circuit board can be electrically connected to the drive controller 4. The drive controller 4 is a driver integrated circuit (IC), which can simultaneously connect to the motherboard and display unit of the electronic device. It works with the signals from the motherboard controller to generate control signals and current output for the display. This structure is easily understood by those skilled in the art and will not be elaborated here. In this embodiment, the target circuit board can also be spaced apart from the substrate 1, as long as electrical conduction is achieved through the electrical connection between the cables. Of course, in this arrangement, as long as the strength of the substrate 1 is sufficient, no support is required.

[0048] As described above, the display panel provided in this application arranges the cables for the display unit on two surfaces of the substrate 1, avoiding bending from the first surface of the substrate 1 to the second surface for connection. This reduces the space required for cable bending and avoids wire wrapping to the same side in the non-display area, thereby effectively reducing the size of the non-display area and effectively realizing the setting of a narrow bezel display panel. This solves the problem in the prior art that the narrow bezel design cannot be achieved due to the large size of the non-display area occupied by the wiring.

[0049] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that there can be three relationships, such as A and / or B. Specifically, it can be understood as: A and B can be included at the same time, A can exist alone, or B can exist alone, and any of the above three situations can be met.

[0050] Further, see attached document. Figure 1In the specific implementation of the display panel provided in this embodiment, the target circuit board is a first circuit board 2, which is fixedly connected to the second surface of the substrate 1 to support the substrate 1.

[0051] It is understandable that when substrate 1 is a PI substrate, it is a flexible substrate material. Therefore, in this embodiment, a first circuit board 2 can be provided as a support for substrate 1 to ensure the strength of substrate 1. The first circuit board 2 can be attached to the second surface of substrate 1. The traces on the first circuit board 2 can be directly electrically connected to the cables on the second surface of substrate 1, or they can be electrically connected through a splitter, connector, or other cooperating structure as needed. It is easy to understand that the orthographic projection of the first circuit board 2 along the thickness direction of the display panel can be the same size as or larger than substrate 1, thereby effectively connecting the cables on the second surface of substrate 1.

[0052] Furthermore, when the first circuit board 2 is provided on the corresponding substrate 1, it can cooperate with the display panel drive controller 4 in at least the following two ways:

[0053] First type: Reference appendix Figure 3 In this embodiment, the display panel includes a first circuit board 2 comprising a target element (not shown in the figure) and traces (not shown in the figure). The target element is fixed on the first circuit board 2 and located in the projection area of ​​the first region within the first circuit board 2. The first end of the trace is connected to a corresponding cable, wherein at least a portion of the trace is connected in series with the target element. The second end of the trace forms a connection point on the first circuit board 2, and the connection point is used to electrically connect to a second circuit board 5 having the drive controller 4 of the display panel.

[0054] The target component is configured to connect and fan out cables via splitters, connectors, and other functional components. In the first configuration described above, the target component is placed on the first circuit board 2. The target component and wiring are arranged on the surface of the first circuit board 2 facing the substrate 1, allowing the cables of the corresponding display array 3 to transmit signals via the wiring or the target component and wiring. The second circuit board 5 can be the same FPC circuit board as the first circuit board 5, or it can be another type of circuit board, as long as it can serve as a connection carrier between the drive controller 4 and the mainboard of the electronic device. In this embodiment, the second circuit board 5 can be part of the display panel or part of a non-display panel, but it is necessary for the display panel and the electronic device to be assembled together. This configuration is easily understood by those skilled in the art. When the second circuit board 5 is part of the display panel, the second circuit board 5 and the first circuit board 2 can be connected as follows: Figure 3The buffer layer 6 shown can be, but is not limited to, a foam structure. Both sides of the buffer layer can be adhered to the first circuit board 2 and the second circuit board 5. In this embodiment, the electrical connection between the first circuit board 2 and the second circuit board 5 can be as follows: Figure 3 As shown, the first circuit board 2 is inclined to the second circuit board 5 at one end of the bottom edge of the display panel away from the substrate 1 via an adapter plate. For example, the adapter plate is connected via an adapter, and the adapter plate is then connected to the drive controller 4 via an adapter to achieve electrical connection with the second circuit board 5. The adapter plate and the second circuit board 5 serve as the output signal line and input signal line of the drive controller 4, respectively. Thus, the first circuit board 2 and the substrate 1 do not need a unified wiring area or bends on the bottom edge side of the display panel, greatly reducing their width on the bottom edge side.

[0055] The second method is detailed in the appendix. Figure 2 The first circuit board 2 and the second region of the substrate 1 are bent together toward the second surface of the substrate 1, wherein the second region of the substrate 1 coincides with one edge of the first region.

[0056] In this configuration, to simplify the structure, the first circuit board 2 and the substrate 1 can be bent directly towards the second surface of the substrate 1, and then electrically connected to the second circuit board 5 with the drive controller 4. This connection is the same as the connection method in the first configuration described above, and will not be repeated here. In this configuration, the cables of the corresponding display units are already connected to the first circuit board 2 on the second surface of the substrate 1. Therefore, the bending area of ​​the first circuit board 2 and the substrate 1 does not need to reserve a unified routing area for the cables, nor does it need to set up components such as splitters and connectors. As a result, the width of the bending area can be set to be smaller, greatly reducing the bezel width of the display panel at the bending point. It is easy to understand that the second area of ​​the substrate 1 can be the bottom edge of the display panel.

[0057] Further, see attached document. Figure 1 In the specific implementation of the display panel provided in this embodiment, the first surface of the substrate 1 further includes a second region, which coincides with one side of the first region. The cable is located on the second surface of the substrate 1 corresponding to the projection area of ​​the second region. The target circuit board is a flexible circuit board with the drive controller 4 of the display panel. The target circuit board is electrically connected to the cable located on the second surface of the substrate 1 corresponding to the projection area of ​​the second region.

[0058] Understandably, in order to enable the display driver to work in conjunction with the cables on the second surface of substrate 1, the target circuit in this embodiment can be configured as a flexible circuit board with a driver controller 4, which is directly electrically connected to the cables on the second surface of substrate 1. Simultaneously, in this embodiment, the cables can be positioned along the edge of the first region, without extending or being positioned outside the first region. Therefore, when the target circuit board is connected to the cables, it can also be connected along the edge of the corresponding first region. The size of the target circuit board can also be made smaller, without occupying space outside the first region, thereby further reducing the bezel width of the display panel.

[0059] Further, see attached document. Figure 4 In the specific implementation of the display panel provided in this embodiment, the substrate 1 is provided with at least one through hole 11; the cable passes through the at least one through hole 11 and is located on the second surface of the substrate 1.

[0060] It is understood that, in order to enable the cable to extend or form a connection point on the second surface of the substrate 1 after being connected to the display unit, this embodiment provides through holes 11 on the substrate 1. The size and number of through holes 11 are not limited here and can be designed and adjusted according to actual needs. The through holes 11 can be set in the first area or outside the first area, and can be designed and adjusted according to the actual wiring type. After the cable is connected to the display unit, it extends through the through hole 11 to the second surface of the substrate 1 and then makes an electrical connection with the first circuit board 2 or the target circuit board. All cables in the above configuration can extend to the second surface of the substrate 1 through the through hole 11.

[0061] Example 2

[0062] Reference Attachment Figure 7 The electronic device provided in this embodiment includes a frame 7 and a display panel. The frame 7 includes a support plate 71, which has a second through hole 72 to connect a first side and a second side. The main board 8 of the electronic device is located on the second side of the support plate 71. The display panel is fixed to the frame 7 on the first side of the support plate 71. The display panel has a display area, which is composed of a plurality of display units located on a first surface of a substrate 1 of the display panel. The display panel has a cable corresponding to each display unit, which is located on a second surface of the substrate 1, opposite to the first surface. The display panel includes a target circuit board, which is electrically connected to the cable located on the second surface of the substrate 1. The target circuit board is electrically connected to the main board 8 through the second through hole 72.

[0063] Understandably, in order to address the problem in existing technologies where the wiring occupies a large area in the non-display area, making it impossible to achieve a narrow bezel design, the electronic device provided in this embodiment sets the connection end of the cable corresponding to the display unit in the display panel on the second surface of the substrate 1. The cable can be directly set in the projection area corresponding to the first area, without having to route the cable around to the bottom edge of the device in the non-display area and then bend it to the back for electrical connection with the drive controller of the display panel. The width of the bottom edge of the device does not need to reserve space for paralleling and bending of the cable and connector, thereby greatly reducing the width of the bottom edge of the device and achieving a narrow bezel for the electronic device.

[0064] The display panel in this embodiment is the same as the display panel in the example. Its structure and working principle are described in detail in Example 1, and will not be repeated here.

[0065] The frame 7 is a closed annular frame structure, which can be, but is not limited to, rectangular, trapezoidal, parallelogram, circular, etc., and serves as the circumferential outer frame of the electronic device. The support plate 71 is a rigid plate structure. At any position in the middle of the thickness direction of the frame 7, the support plate 71 divides the frame 7 into a first-side receiving space and a second-side receiving space. In this embodiment, the display panel is disposed on the first side of the support plate 71, and the main board 8 is disposed on the second side of the support plate 71. The display panel is electrically connected to the main board 8 through a second through hole 72 to drive the display. The shape and size of the second through hole 72 are not limited and can be designed and adjusted according to actual needs. It should be noted that in this embodiment, the second through hole 72 is sealed, isolating and sealing the first and second sides of the support plate 71 to prevent moisture from the display panel side from entering the side where the main board 8 is located through the second through hole 72 and affecting the main board 8.

[0066] Furthermore, in the specific implementation of the electronic device provided in this embodiment, the target circuit board includes a first circuit board 2, a buffer layer 6, and a second circuit board 5 stacked together; the first circuit board 2 is fixed to the second surface of the substrate 1 to support the substrate 1; the second circuit board 5 is electrically connected to the side of the first circuit board 2 away from the substrate 1, the second circuit board 5 has a drive controller 4 for the display panel, and the second circuit board 5 is electrically connected to the motherboard 8 through the second through hole 72.

[0067] It is understandable that, in order to achieve a narrow bezel in electronic devices, in this embodiment, the target components (connected and fanned out in conjunction with cable splitters, connectors, and other functional components) can be placed on the first circuit board 2. The target components and traces can be laid out on the surface of the first circuit board 2 facing the substrate 1, allowing the cables of the corresponding display array 3 to transmit signals via traces or through the target components and traces. The second circuit board 5 can be the same FPC circuit board as the first circuit board 5, or it can be other types of circuit boards, as long as it can serve as a connection carrier between the drive controller 4 and the main board 8. The buffer layer 6 can be, but is not limited to, a foam structure, and both sides of the buffer layer 6 can be adhered to the first circuit board 2 and the second circuit board 5. In this embodiment, the electrical connection between the first circuit board 2 and the second circuit board 5 can be as follows: Figure 3 As shown, the first circuit board 2, at one end corresponding to the bottom edge of the display panel, is inclined to the side away from the substrate 1 via an adapter plate to connect to the second circuit board 5. For example, the adapter plate is connected via an adapter, and the adapter plate is then connected to the drive controller 4 via an adapter to achieve electrical connection with the second circuit board 5. The adapter plate and the second circuit board 5 serve as the output signal line and input signal line of the drive controller 4, respectively. Therefore, the first circuit board 2 and the substrate 1 do not require a unified wiring area or bending on the bottom edge of the display panel, greatly reducing their width on the bottom edge. In this configuration, the first circuit board 2 can also be reused as a shielding structure for the display panel to shield radio frequency signals.

[0068] Furthermore, in a specific implementation of the electronic device provided in this embodiment, the target circuit board includes a first circuit board 2; the first circuit board 2 is fixed to the second surface of the substrate 1 to support the substrate 1, the first circuit board 2 and the second region of the substrate 1 are bent toward the second surface of the substrate 1 together, and the second region of the substrate 1 coincides with one side of the first region; wherein, the end of the first circuit board 2 bent to the second surface of the substrate 1 is connected to a second circuit board 5 having the drive controller 4 of the display panel; the first circuit board 2 is also provided with an electromagnetic coil 9, and the electromagnetic coil 9 is electrically connected to the second circuit board 5 through the first circuit board 2.

[0069] It is understandable that, to simplify the structure, in this embodiment, the first circuit board 2 and the substrate 1 can be bent directly towards the second surface of the substrate 1, and then electrically connected to the second circuit board 5 with the drive controller 4, without the need for an adapter board between the first circuit board 2 and the second circuit board 5. In this configuration, the cables for the corresponding display units are already connected to the first circuit board 2 on the second surface of the substrate 1. Therefore, the bending area of ​​the first circuit board 2 and the substrate 1 does not need to reserve a unified routing area for the cables, nor does it need to set up components such as splitters and connectors. Consequently, the width of the bending area can be set smaller, greatly reducing the bezel width of the display panel at the bending point. It is therefore easy to understand that the second area of ​​the substrate 1 can be the bottom edge of the display panel. Simultaneously, the first circuit board 2 does not need to perform the display function, and therefore, in this embodiment, an electromagnetic coil 9 can be set on the first circuit board 2, for example, as shown in the image. Figure 5 As shown, the electromagnetic coil 9 is arranged around the circumferential edge of the first circuit board 2. It can be used as a transceiver for near field communication (NFC) antenna. Correspondingly, the electromagnetic coil 9 can be electrically connected to the second circuit board 5 along with the first circuit board 2 and then connected to the NFC antenna chip (not shown in the figure) on the motherboard 8 side through the second circuit board 5. This eliminates the need to set the electromagnetic coil in the electronic device housing and reduces costs.

[0070] Furthermore, in a specific implementation of the electronic device provided in this embodiment, the first surface of the substrate 1 further includes a second region, the second region coinciding with one side of the first region, wherein the cable is located on the second surface of the substrate 1 corresponding to the projection area of ​​the second region; the target circuit board is a flexible circuit board having the drive controller 4 of the display panel, and the target circuit board is electrically connected to the cable located on the second surface of the substrate 1 corresponding to the projection area of ​​the second region.

[0071] Understandably, in order to enable the display driver to work in conjunction with the cables on the second surface of substrate 1, the target circuit in this embodiment can be configured as a flexible circuit board with a driver controller 4, which is directly electrically connected to the cables on the second surface of substrate 1. Simultaneously, in this embodiment, the cables can be positioned along the edge of the first region, without extending or being positioned outside the first region. Therefore, when the target circuit board is connected to the cables, it can also be connected along the edge of the corresponding first region. The size of the target circuit board can also be made smaller, without occupying space outside the first region, thereby further reducing the bezel width of the display panel, i.e., the electronic device.

[0072] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
