[0045] Hereinafter, a display module according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0046] Figure 1 It is a perspective view of a display device DD according to an embodiment. Figure 2 yes Figure 1 An exploded perspective view of the display device DD is shown. Figure 3 It is a plan view of a display panel DP involved in one embodiment.

[0047] The display device DD may be a device activated according to an electrical signal. The display device DD may include various embodiments. For example, the display device DD may include a tablet, a laptop, a computer, a smart TV, etc. In one embodiment of the present invention, the display device DD is exemplified as a smart phone.

[0048] like Figure 1As shown, the display device DD may display an image IM on the front surface FS. The front surface FS may be defined parallel to a plane defined by the first direction DR1 and the second direction DR2. The front surface FS includes a transmission area TA and a frame area BZA adjacent to the transmission area TA.

[0049] The display device DD displays an image IM in the transparent area TA. The image IM may include at least one of a static image and a dynamic image. Figure 1 , a clock and a plurality of icons are illustrated as an example of the image IM.

[0050] The transmission area TA may have a quadrilateral shape parallel to the first direction DR1 and the second direction DR2 , respectively. However, this is only an example, and the transmission area TA may have various shapes and is not limited to any one embodiment.

[0051] The frame area BZA is adjacent to the transmission area TA. The frame area BZA may surround the transmission area TA. However, this is only an example, and the frame area BZA may be configured adjacent to only one side of the transmission area TA, or the frame area BZA may be omitted. The display device DD involved in one embodiment of the present invention may include various embodiments, and is not limited to any one embodiment.

[0052] The normal direction of the front surface FS may correspond to the thickness direction DR3 (hereinafter referred to as the third direction) of the display device DD. In one embodiment of the present invention, the front surface (or upper surface) and the back surface (or lower surface) of each component are defined based on the direction of displaying the image IM. The front surface and the back surface are opposite to each other in the third direction DR3.

[0053] On the other hand, the directions indicated by the first direction DR1 to the third direction DR3 are relative concepts and can be changed to other directions. Hereinafter, the first direction to the third direction are directions indicated by the first direction DR1 to the third direction DR3, respectively, and the same symbols are referred to.

[0054] On the other hand, the display device DD of the present invention can sense the user input TC applied from the outside. The user input TC includes various forms of external input such as a part of the user's body, light, heat, or pressure. In addition, the display device DD can sense not only input that contacts the display device DD, but also input that is close to or adjacent to the display device DD.

[0055] In the embodiment of the present invention, the user input TC illustrates the user's hand applied to the front surface FS. However, this is an illustrated example, and as described above, the user input TC may be provided in various ways, and the display device DD may also sense the user input TC applied to the side or back of the display device DD according to the structure of the display device DD, and is not limited to any one embodiment.

[0056] The display device DD may include a window portion WP, a display module DM, a circuit substrate CB, an electronic module EM, and a housing HS. The window portion WP and the housing HS are combined to define the appearance of the display device DD.

[0057] The window portion WP is arranged on the display panel DP and covers the front surface IS of the display panel DP. The window portion WP may include an optically transparent insulating material. For example, the window portion WP may include glass or plastic. The window portion WP may have a multi-layer or single-layer structure. For example, the window portion WP may have a laminated structure of a plurality of plastic films bonded by an adhesive, or may have a laminated structure of a glass substrate and a plastic film bonded by an adhesive.

[0058] The window portion WP includes a front surface FS exposed to the outside. The front surface FS of the display device DD may be substantially defined by the front surface FS of the window portion.

[0059] Specifically, the transmission area TA may be an optically transparent area. The transmission area TA may have a shape corresponding to the active area AA. For example, the transmission area TA overlaps with the front surface of the active area AA or at least a portion of the front surface. The image IM displayed in the active area AA of the display panel DP may be recognized externally through the transmission area TA.

[0060] The frame area BZA may be an area with a relatively lower light transmittance than the transmission area TA. The frame area BZA defines the shape of the transmission area TA. The frame area BZA is adjacent to the transmission area TA and may surround the transmission area TA.

[0061] The frame area BZA may have a predetermined color. When the window portion WP is provided as glass or plastic, the frame area BZA may be a color layer printed or deposited on one side of the glass or plastic substrate. Alternatively, the frame area BZA may also be formed by coloring a corresponding area of ​​the glass or plastic substrate.

[0062] The frame area BZA covers the non-active area NAA of the display panel DP, thereby preventing the non-active area NAA from being recognized from the outside. On the other hand, this is an example, and the frame area BZA may be omitted for the window portion WP according to an embodiment of the present invention.

[0063] The display module DM may include a display panel DP, an input sensing sensor ISS, an anti-reflection member POL, and an adhesive member ADL. A predetermined hole HA may be defined in the display module DM. The hole HA may pass through any one of the display panel DP, the anti-reflection member POL, and the adhesive member ADL.

[0064] The display panel DP may display an image IM and sense an external input TC. The display panel DP includes a front surface IS including an active area AA and a non-active area NAA. The active area AA may be an area activated according to an electrical signal.

[0065] In one embodiment of the present invention, the active area AA may be an area where the image IM is displayed. The transparent area TA at least overlaps with the active area AA. For example, the transparent area TA overlaps with the front surface or at least a portion of the active area AA. Thus, the user can recognize the image IM through the transparent area TA.

[0066] The non-active area NAA may be an area covered by the border area BZA. The non-active area NAA is adjacent to the active area AA. The non-active area NAA may surround the active area AA. A driving circuit or driving wiring, etc. for driving the active area AA may be configured in the non-active area NAA.

[0067] Various signal lines or pads PD for supplying electrical signals to the active area AA, or electronic components, etc. may be disposed in the non-active area NAA. The non-active area NAA is covered by the frame area BZA so as not to be recognized from the outside.

[0068] In one embodiment of the present invention, the display panel DP is assembled in a flat state with the active area AA and the inactive area NAA facing the window portion WP. However, this is an illustrated example, and a portion of the inactive area NAA in the display panel DP may be bent. In this case, a portion of the inactive area NAA faces the back side of the display device DD, thereby reducing the border area BZA in the front surface of the display device DD. Alternatively, the display panel DP may be assembled in a state in which a portion of the active area AA is also bent. Alternatively, in the display panel DP involved in one embodiment of the present invention, the inactive area NAA may be omitted.

[0069] The hole HA may have a relatively high transmittance compared to the effective area AA for the same area. The hole HA is defined at a position overlapping with the electronic module EM described later on a plane. At least a portion of the hole HA may be surrounded by the effective area AA. In the combined state of the display device DD involved in one embodiment of the present invention, the hole HA may be defined at a position marked in the transmission area TA and away from the frame area BZA.

[0070] In one embodiment of the present invention, the hole HA is away from the non-active area NAA. It means that the hole HA is defined inside the active area AA, so that the hole HA is surrounded by the active area AA at all edge positions. Specifically, the hole HA may be located at the upper right end of the display panel DP. However, it is not limited thereto.

[0071] The input sensing sensor ISS may be configured on the upper portion of the display panel DP. The input sensing sensor ISS may be configured on an area other than an area overlapping with the hole HA of the display panel DP. The input sensing sensor ISS may include a plurality of sensors. The plurality of sensors may form electrostatic capacitance with each other. When a touch is applied from the outside, the electrostatic capacitance formed by the plurality of sensors changes, and the display device may sense the change in electrostatic capacitance. The input sensing sensor ISS may sense an external input TC applied from the outside. That is, the input sensing sensor ISS may sense an external input TC provided from the window portion WP.

[0072] The anti-reflection component POL may be disposed between the window WP and the input sensing sensor ISS. The anti-reflection component POL reduces the reflectivity of external light (hereinafter referred to as external light) incident from the outside of the window WP relative to the display panel DP. In one embodiment of the present invention, the anti-reflection component POL may include a polarizing component.

[0073] The adhesive component ADL is disposed between the anti-reflection component POL and the window portion WP. The adhesive component ADL combines the anti-reflection component POL and the window portion WP. In the case where the anti-reflection component POL involved in the present invention is a color filter formed on the display panel DP, the adhesive component ADL can also substantially combine the display panel DP and the window portion WP. The adhesive component ADL may include an optical clear adhesive, an optical clear resin, or a pressure sensitive adhesive, and is not limited to any one embodiment as long as it is optically transparent.

[0074] The circuit substrate CB may be connected to the display panel DP. The circuit substrate CB may include a flexible substrate CF and a main substrate MB. The flexible substrate CF may include an insulating film and a conductive wiring mounted on the insulating film. The conductive wiring is connected to the pad PD to electrically connect the circuit substrate CB and the display panel DP.

[0075] In one embodiment of the present invention, the flexible substrate CF is assembled in a bent state. Thus, the main substrate MB is disposed on the back of the display panel DP, so that it can be stably accommodated in the space provided by the housing HS. On the other hand, in one embodiment of the present invention, the flexible substrate CF can also be omitted, and the main substrate MB can be directly connected to the display panel DP.

[0076] The main substrate MB may include signal lines and electronic components not shown. The electronic components may be connected to the signal lines and electrically connected to the display panel DP. The electronic components generate various electrical signals, such as signals for generating an image IM or for sensing an external input TC, or process the sensed signals. On the other hand, a plurality of main substrates MB may be provided corresponding to each electrical signal for generation and processing, but are not limited to any one embodiment.

[0077] On the other hand, in the display device DD according to an embodiment of the present invention, the driving circuit that provides the electrical signal to the active area AA may also be directly mounted on the display panel DP. In this case, the driving circuit is mounted in a chip manner, or may be formed together with the pixel PX. In this case, the area of ​​the circuit substrate CB may be reduced or omitted. The display device DD according to an embodiment of the present invention includes various embodiments and is not limited to any one embodiment.

[0078] The electronic module EM may be disposed at the lower portion of the window portion WP. Specifically, the electronic module EM may be disposed on the back of the display panel DP, or at least a portion of the electronic module EM may be disposed in the hole HA. According to the present invention, the electronic module EM may be surrounded by the active area AA. That is, compared with the case where the electronic module EM is disposed in the non-active area NAA, an increase in the frame area BZA may be prevented.

[0079] In one embodiment of the present invention, the electronic module EM may include a camera module. The lens of the camera module may be aligned with the second hole HA2 (refer to FIG. Figure 5d ) The second hole HA2 may overlap with the transmission area TA in the third direction DR3. Thus, the lens of the camera module can recognize the image IM through the transmission area TA. The electronic module EM can easily recognize the external subject through the hole HA.

[0080] like Figure 3 As shown, the display panel DP includes a base substrate BS, a plurality of pixels PX, a plurality of signal lines (GL, DL, PL), a power pattern VDD, and a plurality of display pads DPD.

[0081] The active area AA and the non-active area NAA may be areas provided by the base substrate BS. The base substrate BS may include an insulating substrate. For example, the base substrate BS may be composed of a glass substrate, a plastic substrate, or a combination thereof.

[0082] The signal lines (GL, DL, PL) are connected to the pixels PX to transmit electrical signals to the pixels PX. Among the signal lines included in the display panel DP, the scan lines GL, the data lines DL, and the power lines PL are illustrated. However, this is an example, and the signal lines may also include at least one of the power lines, the initialization voltage lines, and the light emitting control lines, and are not limited to any one embodiment.

[0083] The pixel PX may be arranged in the active area AA. In one embodiment of the present invention, a signal circuit diagram of one pixel PX among a plurality of pixels is enlarged for illustration. The pixel PX may include a first thin film transistor TR1, a capacitor CPP, a second thin film transistor TR2, and a light emitting element EE.

[0084] The first thin film transistor TR1 is connected to the scan line GL and the data line DL. The capacitor CPP is connected to the first thin film transistor TR1 and the power line PL. The second thin film transistor TR2 is connected to the first thin film transistor TR1, the capacitor CPP and the light emitting element EE. The first thin film transistor TR1, the capacitor CPP and the second thin film transistor TR2 can control the action of the light emitting element EE.

[0085] The light emitting element EE may emit light at a time and intensity corresponding to the data signal transmitted through the data line DL. For example, the light emitting element EE may include an organic light emitting element, a quantum dot light emitting element, an electrophoretic element, or an electrowetting element.

[0086] The light emitting element EE is connected to the power supply terminal VSS, thereby receiving a power supply signal (hereinafter referred to as a second power supply signal) different from the power supply signal (hereinafter referred to as a first power supply signal) provided by the power supply line PL. The light emitting element EE can generate light corresponding to the difference between the electric signal provided from the second thin film transistor TR2 and the second power supply signal. On the other hand, this is an illustrated example, and each pixel PX may include electronic components having various structures and arrangements, and is not limited to any one embodiment.

[0087] The pixels PX are arranged around the hole HA. In one embodiment of the present invention, the boundary between the hole HA and the active area AA may have a closed curve shape. In one embodiment of the present invention, a circle is exemplified as the boundary between the hole HA and the active area AA.

[0088] The power pattern VDD is disposed in the non-active area NAA. In one embodiment of the present invention, the power pattern VDD is connected to a plurality of power lines PL. Thus, the display panel DP includes the power pattern VDD, so that the same first power signal can be provided to each pixel PX.

[0089] The display pad DPD may include a first pad P1 and a second pad P2. A plurality of first pads P1 are provided so that they can be connected to each data line DL respectively. The second pad P2 is connected to the power pattern VDD so that it can be electrically connected to the power line PL. The display panel DP can increase the electrical signal provided from the outside to the pixel PX through the display pad DPD. On the other hand, the display pad DPD may include pads for receiving other electrical signals in addition to the first pad P1 and the second pad P2, and is not limited to any one embodiment.

[0090] Figure 4 A flowchart showing a method for manufacturing a display device according to an embodiment of the present invention. Figure 5a , Figure 5b , Figure 5c as well as Figure 5d A method for manufacturing a display device according to an embodiment is shown. Figure 6 It is along Figure 5c Cross-sectional view taken along line I-I'. Figure 7a as well as Figure 7b yes Figure 6 A variant embodiment of .

[0091] like Figure 4 As shown, a method for manufacturing a display device according to an embodiment of the present invention may include a preparation step S100 , a punching step S200 , a laser irradiation step S300 , and an arrangement step S400 .

[0092] Reference Figure 4 as well as Figure 5a , the preparation step S100 involved in one embodiment of the present invention may be a step of preparing a display module DM. The display module DM may include an active area AA and a non-active area NAA of the display panel DP. The non-active area NAA may surround the active area AA. The perforated area PR-HA may overlap with the active area AA. Specifically, the perforated area PR-HA may be configured adjacent to an edge position of the active area AA. The input sensing sensor ISS may not be configured in the perforated area PR-HA.

[0093] Reference Figure 4 as well as Figure 5b , the punching step S200 may be a step of punching holes in the punching area PR-HA using a press. The punching step S200 may be a step of physically punching holes in the punching area PR-HA. For example, the punching step S200 may be a step of forming a first hole HA1 in the display module DM. In the punching step S200 involved in an embodiment, the punching direction may be the thickness direction of the display panel DP. For example, the punching direction may be the direction from the display panel DP toward the adhesive component ADL. However, it is not limited thereto.

[0094] In an embodiment of the present invention, the first hole HA1 may have a circular shape. However, it is not limited thereto. The active area AA may surround the first hole HA1. The first hole HA1 may have a first diameter DI1.

[0095] Reference Figure 4 as well as Figure 5c , the laser irradiation step S300 may be a step of irradiating laser to the laser area LA. The laser area LA may surround the first hole HA1. The laser area LA may have a circular shape. However, it is not limited thereto. The laser area LA may be configured separately from the first hole HA1. A remaining area RA may be defined between the laser area LA and the first hole HA1. In one embodiment, the remaining area RA may also be omitted. In the laser irradiation step S300, laser may be irradiated to the laser area LA. That is, in the laser irradiation step S300, the laser area LA may be removed. While removing the laser area LA, the remaining area RA may also be removed together. Thus, the first hole HA1 may be processed into the second hole HA2 (refer to Figure 5d ). The second hole HA2 may have a second diameter DI2. The second diameter DI2 may be a diameter of the laser area LA. The second diameter DI2 may be greater than the first diameter DI1.

[0096] Reference Figure 6 ,exist Figure 5c In the laser irradiation step S300, heat H may be generated. Specifically, heat H may be generated in the step of irradiating the laser LZ to the laser area LA. The generated heat H may be dissipated to the outside through the remaining area RA. As the heat H is dissipated to the outside, thermal damage to the display module DM may be minimized.

[0097] According to other embodiments of the present invention, Figure 7a As shown, the anti-reflection component POL and the adhesive component ADL can be omitted in the display module DM. The same is applicable to the display panel DP. Figure 5a as well as Figure 5b In the step of irradiating the laser light LZ to the display panel DP, heat H may be generated. The generated heat H may be dissipated to the outside through the remaining area RA-1. Thus, thermal damage to the display panel DP may be minimized.

[0098] According to other embodiments of the present invention, Figure 7b As shown, the adhesive component ADL can be omitted in the display module DM. The same is applicable to the display panel DP and the anti-reflection component POL. Figure 5a as well as Figure 5b. In the step of irradiating the laser LZ to the display panel DP and the anti-reflection component POL, heat H may be generated. The generated heat H can be dissipated to the outside through the remaining area RA-2. Thus, the thermal damage to the display panel DP and the anti-reflection component POL can be minimized. Although not shown in the figure, according to other embodiments of the present invention, the display module DM may include an input sensing panel TSP on the adhesive component ADL instead of configuring the input sensing sensor ISS between the display panel DP and the anti-reflection component POL. The same may be applied to the input sensing panel TSP Figure 5a to Figure 5d The process is used to form HA holes.

[0099] Reference Figure 4 as well as Figure 5d , the arrangement step S400 may be a step of configuring the electronic module EM in the second hole HA2. In one embodiment of the present invention, the electronic module EM may be a camera module. The lens of the camera module may overlap with the second hole HA2 in the third direction DR3. The second hole HA2 may overlap with the transmission area TA in the third direction DR3. Thus, the lens of the camera module may recognize the image IM through the transmission area TA.

[0100] Figure 8a is a plan view of a display module according to an embodiment. Figure 8b It is along Figure 8a Ⅱ-Ⅱ' cross-sectional view.

[0101] The method for manufacturing the display module DM- 1 according to an embodiment of the present invention may further include a step of disposing a light shielding member BM in at least a portion of the inner side of the second hole HA2 - 1 .

[0102] For example, Figure 8a As shown in FIG. 1 , the light shielding member BM may surround the inner side of the second hole HA2 - 1 . Figure 8b As shown, the light shielding member BM may surround only a portion of the inner side of the second hole HA2-1. The light shielding member BM may have a predetermined color. When the electronic module EM is arranged in the second hole HA2-1, the light shielding member BM covers the wiring of the electronic module EM to prevent the wiring from being recognized from the outside.

Fig.10 It is along Figure 9b The following is a cross-sectional view of III-III'. Figure 4 Sequence of manufacturing method of display device Figure 1 Let me explain.

[0104] Reference Figure 4 as well as Figure 9a , the preparation step S100 involved in one embodiment of the present invention may be a step of preparing a display module DM-2. The display module DM-2 may include an active area AA and a non-active area NAA of the display panel DP. The non-active area NAA may surround the active area AA. The descriptions other than this may be similarly applicable Figure 5a Description.

[0105] Reference Figure 4 as well as Figure 9b The punching step S200 may be a step of punching a hole in the display module DM-2. For example, it may be a step of physically punching a hole in the display module DM-2 using a press. In the punching step S200, a hole HA1-1 and a burr BR may be formed in the display module DM-2. The burr BR will inevitably occur through the punching process of the press.

[0106] In the punching step S200 involved in one embodiment, the punching direction may be the thickness direction of the display panel DP. For example, the punching direction may be the direction from the display panel DP toward the adhesive component ADL. According to the punching direction, burrs BR may be formed at various positions. For example, burrs may be formed on the adhesive component ADL. However, the punching direction and the position where the burrs BR are formed are not limited thereto.

[0107] The other instructions apply equally Figure 5b Description.

[0108] Reference Figure 4 , Fig.9c as well as Fig.10 , the laser irradiation step S300 may be a step of irradiating the burr BR with laser. That is, the laser irradiation step S300 may be a step of irradiating the laser to remove the burr BR. The laser may only remove the burr BR without changing the size of the hole HA1-1. That is, the manufacturing method of the display device involved in one embodiment of the present invention may include physically punching once to form the hole HA1-1. Then, the laser may be used a second time to perform micro-machining on the hole HA1-1. For example, Fig.10 As shown, the micromachining can remove the burr BR by laser. However, the position of the burr BR is an example and is not limited to this.

[0109] Towards Fig.9c The laser area LA of the embodiment shown removes the burrs BR with laser (not shown), so the intensity of the laser may be lower than the intensity of the laser (not shown) irradiated to the laser area LA in FIG. 5C . Thus, the degree of thermal damage to the display module DM- 2 can be reduced.

[0110] Reference Figure 4 as well as Figure 9d, the arrangement step S400 may be a step of configuring the electronic module EM in the hole HA1-1. Other descriptions may be similarly applicable. Figure 5d Description.
