[0049] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings.

[0050] Figure 1 This is a perspective view of a display device according to an embodiment of the present disclosure. Figure 2 This is an exploded perspective view of a display device according to an embodiment of the present disclosure.

[0051] Reference Figure 1 as well as Figure 2 The display device DD can be a device activated by an electrical signal. The display device DD can include various embodiments. For example, the display device DD can include a tablet computer, a laptop computer, a computer, a smart TV, etc. In this embodiment, the display device DD is exemplarily shown as a smartphone.

[0052] The display device DD can display an image IM on the front FS. The front FS can be defined as parallel to the plane defined by the first direction DR1 and the second direction DR2 intersecting the first direction DR1. The front FS can include a transmission region TA and a border region BZA adjacent to the transmission region TA.

[0053] The display device DD can display an image IM in the transmission region TA. The image IM can include at least one of a still image and a moving image. Figure 1 In the example of an image-based IM, a table window and icons are shown.

[0054] The transmission region TA can have a quadrilateral shape that is parallel to both the first direction DR1 and the second direction DR2. However, this is only illustrative, and the transmission region TA according to one embodiment of the present disclosure can have various shapes and is not limited to any one embodiment.

[0055] The border region BZA may have a predetermined color. The border region BZA may be a region with relatively low light transmittance compared to the transmission region TA. The border region BZA may be adjacent to the transmission region TA. The border region BZA may define the shape of the transmission region TA. The border region BZA may surround the transmission region TA. However, this is only illustrative; according to one embodiment of this disclosure, the border region BZA may be configured to be adjacent to only one side of the transmission region TA, or it may be omitted.

[0056] The normal direction of the front FS can correspond to the thickness direction of the display device DD (hereinafter, the third direction DR3). In this embodiment, the front (or top) and back (or bottom) surfaces of each component are defined based on the direction of the displayed image IM. The front and back surfaces can be opposite each other in the third direction DR3. The third direction DR3 can be a direction that intersects with the first direction DR1 and the second direction DR2. The first direction DR1, the second direction DR2, and the third direction DR3 can be orthogonal to each other.

[0057] On the other hand, the directions pointed to by the first direction DR1, the second direction DR2, and the third direction DR3 are relative concepts and can be converted into other directions. Furthermore, in this specification, the surface defined by the first direction DR1 and the second direction DR2 can be defined as a plane, and the case of "observing on a plane" can be defined as the case of viewing from the third direction DR3.

[0058] According to an embodiment of this disclosure, the display device DD can sense external input TC applied from the outside. External input TC can include various forms of external input such as a part of the user's body, light, heat, or pressure. Furthermore, the display device DD can sense not only inputs in contact with the display device DD, but also inputs that are nearby.

[0059] The display device DD may include a window 100, an electronic module 200, a control module 300, and a housing 400. According to an embodiment of the present disclosure, the window 100 and the housing 400 can be combined to form the appearance of the display device DD.

[0060] Window 100 can be disposed above electronic module 200 and cover the front surface IS of electronic module 200. Window 100 may include an optically transparent insulating material. For example, window 100 may include a glass substrate, a sapphire substrate, or a plastic film. Window 100 may have a multilayer or single-layer structure. For example, window 100 may have a stacked structure of multiple plastic films bonded by adhesive, or a stacked structure of a glass substrate and a plastic film bonded by adhesive.

[0061] Window 100 may include a front FS exposed to the outside. The front FS of the display device DD may be substantially defined by the front FS of window 100.

[0062] Electronic module 200 can be configured below window 100. Electronic module 200 can display image IM and sense external input TC. Electronic module 200 may include a display area AA and a non-display area NAA, including the front IS. Display area AA can be an area activated according to an electrical signal.

[0063] According to one embodiment of the present disclosure, the display area AA can be an area for displaying an image IM and simultaneously an area for sensing external input TC. The transmission area TA can overlap with the display area AA. For example, the transmission area TA can overlap the entire surface or at least a portion of the display area AA. Thus, a user can visually identify the image IM or provide external input TC through the transmission area TA. However, this is illustrative, and it is also possible that, within the display area AA according to one embodiment of the present disclosure, the area for displaying the image IM and the area for sensing external input TC can be separated from each other, and the method is not limited to any particular embodiment.

[0064] The non-display area NAA can be the area covered by the border area BZA. The non-display area NAA can be adjacent to the display area AA. The non-display area NAA can surround the display area AA. Driver circuits or driver wiring can be configured in the non-display area NAA.

[0065] According to one embodiment of the present disclosure, the electronic module 200 can be assembled in a flat state with the display area AA and the non-display area NAA facing the window 100. However, this is only illustrative, and a portion of the non-display area NAA according to one embodiment of the present disclosure can be bent. In this case, a portion of the non-display area NAA faces the back of the electronic module 200, thereby reducing the bezel area BZA in the front FS of the display device DD. However, this is only illustrative, and the non-display area NAA according to one embodiment of the present disclosure may also be omitted.

[0066] The electronic module 200 may include a display module DM, a first circuit section CP1, and a second circuit section CP2. The display module DM may include a display panel DP and an input sensor ISP.

[0067] The display panel DP can be a structure that substantially generates the image IM. The image IM generated by the display panel DP is displayed on the front IS through the display area AA, so that it can be visually recognized by the user from the outside through the transmission area TA. According to an embodiment of this disclosure, the display panel DP can be a light-emitting display panel, without particular limitation. For example, the display panel DP can be an organic light-emitting display panel or a quantum dot light-emitting display panel. The light-emitting layer of the organic light-emitting display panel may include organic light-emitting materials. The light-emitting layer of the quantum dot light-emitting display panel may include quantum dots or quantum rods, etc.

[0068] The input sensor ISP can be configured on the display panel DP. The input sensor ISP can sense external input TC applied from the outside.

[0069] The first circuit section CP1 can be electrically connected to the display panel DP. The first circuit section CP1 can connect the display panel DP and the control unit 310. The first circuit section CP1 can be connected to the display pads PDD of the display panel DP, which are located in the non-display area NAA. The first circuit section CP1 can provide electrical signals for driving the display panel DP to the display panel DP. These electrical signals can be generated in the control unit 310.

[0070] The second circuit section CP2 can be electrically connected to the input sensor ISP. The second circuit section CP2 can connect the input sensor ISP and the control unit 310. The second circuit section CP2 can be connected to the sensing pad PDS of the input sensor ISP, which is located in the non-display area NAA. The second circuit section CP2 can provide an electrical signal to the input sensor ISP for driving the input sensor ISP. This electrical signal can be generated in the control unit 310.

[0071] However, this is illustrative. In each of the first circuit section CP1 and the second circuit section CP2 according to an embodiment of the present disclosure, a circuit chip (not shown) may be mounted in a chip-on-film (COF) manner. The circuit chip may generate electrical signals required for the operation of the display panel DP or the input sensor ISP based on control signals transmitted from the control section 310.

[0072] The control module 300 can be configured below the electronic module 200. The control module 300 may include a control unit 310 and a power supply unit 320.

[0073] The control unit 310 can provide electrical signals to the electronic module 200. The control unit 310 may include various functional modules for driving the electronic module 200 and connectors for power supply. The functional modules may include wireless communication modules, image input modules, audio input modules, memory, external interfaces, light-emitting modules, light-receiving modules, and camera modules. The functional modules may be mounted on a motherboard. The motherboard may include a rigid printed circuit board. A portion of the functional modules may not be mounted on the motherboard but may be electrically connected to the motherboard via a flexible circuit film.

[0074] The first circuit section CP1 and the second circuit section CP2 can each be connected to the control section 310. However, this is illustrative. In an electronic module 200 according to an embodiment of the present disclosure, the display panel DP and the input sensor ISP can be connected to different control sections 310, and either the first circuit section CP1 or the second circuit section CP2 may not be connected to the control section 310. This is not limited to any particular embodiment.

[0075] The power supply unit 320 can supply the power required for the overall operation of the display device DD. The power supply unit 320 may include a common battery module.

[0076] The housing 400 can be disposed below the control module 300. The housing 400, together with the window 100, can form the appearance of the display device DD. The housing 400 can include a material that is relatively rigid compared to the electronic module 200.

[0077] In one embodiment of this disclosure, a housing 400 formed from a single body is illustrated, but the invention is not limited thereto. For example, the housing 400 according to one embodiment of this disclosure may include multiple bodies assembled with each other. For example, the housing 400 may include multiple frames and / or panels made of glass, plastic, or metal. The housing 400 may provide a predetermined receiving space. The electronic module 200 and the control module 300 are received within said receiving space, thereby being protected from external impacts.

[0078] Figure 3 This is a flowchart illustrating a display module inspection method according to an embodiment of the present disclosure. Figure 4 This is a top view showing a first circuit section and a second circuit section arranged on a workbench according to an embodiment of the present disclosure.

[0079] Reference Figure 3 as well as Figure 4 On the worktable ST, a first mounting section SP1 and a second mounting section SP2 can be defined. The first mounting section SP1 and the second mounting section SP2 can refer to the areas recessed from the top surface of the worktable ST.

[0081] The first circuit section CP1 can be disposed on the first mounting section SP1 of the worktable ST (S200). The position of the first circuit section CP1 on the worktable ST can be guided by the first mounting section SP1.

[0082] The first circuit section CP1 may include a first circuit film CF1 and a first connector CN1. The first circuit film CF1 may be a flexible circuit film. The first circuit film CF1 can transmit signals transmitted through the first connector CN1 to the display panel DP (see reference). Figure 2 ).

[0083] The first connector CN1 can be disposed on the first circuit film CF1. The first connector CN1 can be a substrate-to-substrate type connector. The substrate-to-substrate type connector can be composed of a female connector bracket in which multiple female terminals are symmetrically arranged and joined together, or a male connector bracket in which multiple male terminals are symmetrically arranged and joined together. However, this is illustrative, and the type of first connector CN1 according to an embodiment of the present disclosure is not limited to the example described, and may include other types of connectors.

[0084] The second circuit section CP2 and the guide section GP can be disposed on the first circuit section CP1 and the worktable ST (S300). The position of the second circuit section CP2 can be guided by the second mounting section SP2.

[0085] The second circuit section CP2 may include a second circuit film CF2 and a second connector CN2. The second circuit film CF2 may be disposed on top of the first circuit film CF1. The second circuit film CF2 may be a flexible circuit film. The second circuit film CF2 can transmit the signal transmitted through the second connector CN2 to the input sensor ISP (see reference). Figure 2 ).

[0086] The second connector CN2 can be disposed on the second circuit film CF2. In a plane, the second circuit film CF2 and the second connector CN2 can overlap with the first circuit film CF1. In a plane, the first connector CN1 and the second connector CN2 can not overlap. The second connector CN2 can have a substantially the same structure as the first connector CN1.

[0087] The guide portion GP and the second circuit film CF2 can be provided integrally. That is, the guide portion GP can be a flexible circuit film. In a plane, a portion of the guide portion GP may not overlap with the first circuit portion CP1. For example, the guide portion GP can be provided by protruding from a region of the second circuit film CF2 in both the first direction DR1 and the second direction DR2.

[0088] Unlike the embodiments disclosed herein, without the guide portion GP, ​​the second circuit portion CP2 overlaps entirely with the first circuit portion CP1. Therefore, the position of the second circuit portion CP2 cannot be guided by the second mounting portion SP2 of the worktable ST. If the position of the second circuit portion CP2 deviates, when the second inspection connector TC2 (refer to...) is... Figure 7 When the first inspection connector TC1 (refer to the second connector CN2) is connected to the second connector CN2, damage to the pins of the second connector CN2 or deformation of the second connector CN2 may occur, resulting in poor fastening. However, according to this disclosure, a portion of the guide portion GP connected to the second circuit section CP2 can not overlap with the first circuit section CP1 on a plane. The guide portion GP can be guided by the second mounting portion SP2. The second circuit section CP2 can be configured in a predetermined position. Therefore, it is possible to prevent damage when the first inspection connector TC1 (refer to the second connector CN2) is connected to the second connector CN2. Figure 7 ) and the second inspection connector TC2 (refer to Figure 7 This addresses the potential for poor fastening when the module is connected to the first connector CN1 and the second connector CN2, respectively. Therefore, a display module inspection method with improved reliability can be provided.

[0089] Multiple holes HA can be defined at the boundary between the second circuit film CF2 and the guide portion GP. The multiple holes HA can be defined along the first direction DR1 and the second direction DR2. Each of the multiple holes HA can have a triangular shape. However, this is illustrative, and the shapes of the multiple holes HA according to an embodiment of this disclosure can be provided in various shapes that facilitate the removal of the guide portion GP. In a plane, the multiple holes HA can overlap with the first circuit film CF1.

The second circuit section CP2 can be disposed in a predetermined position. The second inspection connector TC2 (see reference) can be used. Figure 7 It is combined with the second connector CN2. This prevents poor tightening that may occur when tightening the second inspection connector TC2 and the second connector CN2. Therefore, it provides a display module inspection method with improved reliability.

[0096] In one embodiment of this disclosure, a first depth TK-SP1 from the top surface ST-U of the worktable ST to the top surface SP1-U of the first placement part SP1 is shown to be the same as a second depth TK-SP2 from the top surface ST-U of the worktable ST to the top surface SP2-U of the second placement part SP2, but this is not a limitation. For example, in one embodiment of this disclosure, the second depth TK-SP2 may be less than the first depth TK-SP1. Therefore, the second placement part SP2 can easily guide the guide part GP.
