Mode for Carrying Out the Invention
[0021] Hereinafter, some embodiments of the present disclosure will be described in detail with reference to exemplary drawings. When adding reference numerals to the components of each drawing, for the same components, even if they are shown on other drawings, the same numerals may be used as much as possible. In the description of the present disclosure, when it is determined that a specific description of a related known configuration or function may obscure the gist of the present disclosure, the detailed description thereof will be omitted. When terms such as "including", "having", "consisting of", etc. mentioned in this specification are used, other parts may be added unless "only" is used. When a component is expressed in the singular, it can include the case of including a plurality, unless there are specific descriptions.
[0022] Also, when describing the components of the present disclosure, terms such as first, second, A, B, (a), (b), etc. can be used. These terms are only for distinguishing the components from other components, and the essence, order, sequence, number, etc. of the components are not limited by these terms.
[0023] In the description of the positional relationship of components, when it is described that two or more components are "connected", "coupled", or "joined", it should be understood that two or more components can be directly "connected", "coupled", or "joined", but it is also possible that two or more components and other components are further "interposed" and "connected", "coupled", or "joined". Here, the other components may be included in one or more of the two or more components that are "connected", "coupled", or "joined" to each other.
[0024] On the other hand, if numerical values or corresponding information (e.g., levels) relating to components are mentioned, even without further explicit mention, these numerical values or corresponding information may be interpreted as including a range of errors that can occur due to various factors (e.g., process factors, internal or external shocks, noise, etc.).
[0025] Various embodiments of this disclosure will be described in detail below with reference to the attached drawings.
[0026] Figure 1 shows a display device 100 according to an embodiment of the present disclosure.
[0027] The display device 100 according to the embodiments of this disclosure may include a display panel 110 and a drive circuit 120, etc.
[0028] The display panel 110 may include a substrate 111 and a plurality of subpixels SP formed on the substrate 111.
[0029] The substrate 111 may include a display area DA on which video can be displayed and a non-display area NDA on which video cannot be displayed. The display area DA and the non-display area NDA may be areas of the display panel 110. That is, the display panel 110 may include a display area DA and a non-display area NDA. Here, the non-display area NDA is also called a bezel.
[0030] The substrate 111 can be divided into multiple regions. For example, the substrate 111 can include an upper region TOP, a lower region BOT, and an intermediate region MID. The upper region TOP can include a pad region PA. The lower region BOT can be located furthest from the pad region PA among the first to third regions A1, A2, and A3. The intermediate region MID can be located between the upper region TOP and the lower region BOT.
[0031] The display area DA may include the upper display area DA_TOP contained within the upper area TOP, the lower display area DA_BOT contained within the lower area BOT, and the intermediate display area DA_MID contained within the intermediate area MID. That is, the substrate 111 may include the upper area TOP containing the upper display area DA_TOP, the lower area BOT containing the lower display area DA_BOT, and the intermediate area MID containing the intermediate display area DA_MID. The upper area TOP may include the pad area PA.
[0032] The non-display area (NDA) is an outer area of the display area (DA) and may include a pad area (PA) adjacent to the upper display area (DA_TOP) rather than the intermediate display area (DA_MID).
[0033] The substrate 111 may be a flexible substrate.
[0034] The substrate 111 may have an upper edge line TEL, a lower edge line BEL, a first boundary line BL1, and a second boundary line BL2.
[0035] The upper edge line TEL and the lower edge line BEL may be cutting lines of the substrate 111. The upper edge line TEL may be the edge line of the substrate 111 near the pad area PA, and the lower edge line BEL may be the edge line of the substrate 111 on the opposite side of the upper edge line TEL.
[0036] The substrate 111 can be bent near the upper edge line TEL. Therefore, the pad area PA and the components connected to it (drive circuit 120, flexible printed circuit board 130, printed circuit board 140) can be located beneath the substrate 111.
[0037] The first boundary line BL1 may be a virtual line indicating the boundary between the upper display area DA_TOP and the intermediate display area DA_MID, and the second boundary line BL2 may be a virtual line indicating the boundary between the lower display area DA_BOT and the intermediate display area DA_MID.
[0038] Multiple subpixels SP can be placed in the display area DA. Multiple subpixels SP can be placed in each of the upper display area DA_TOP, the middle display area DA_MID, and the lower display area DA_BOT.
[0039] In the display device 100 according to the embodiment of the present disclosure, the intermediate region MID may include an inwardly recessed waist region WA. This allows the intermediate region MID to have a width smaller than the upper display region DA_TOP and / or the lower display region DA_BOT.
[0040] Within the intermediate region MID, the waist region WA can represent the region between the valley line Lv and the edge EDG of the substrate 111. The valley line Lv may be a virtual line extending in a first direction through the point where the substrate 111 is most deeply indented (Pv, hereinafter referred to as the "valley point").
[0041] For example, at the first boundary line BL1 between the upper display area DA_TOP and the intermediate display area DA_MID, the width of the intermediate display area DA_MID may narrow as you approach its center. Similarly, at the second boundary line BL2 between the lower display area DA_BOT and the intermediate display area DA_MID, the width of the intermediate display area DA_MID may narrow as you approach its center. Here, width can refer to the length in the first direction.
[0042] For example, the maximum width of the intermediate display area DA_MID may be smaller than the maximum width of the upper display area DA_TOP and the maximum width of the lower display area DA_BOT.
[0043] In the display device 100 according to the embodiments of this disclosure, the drive circuit 120 can be electrically connected to the pad area PA within the non-display area NDA. For example, the drive circuit 120 is mounted on a flexible printed circuit board 130, and one side of the flexible printed circuit board 130 can be connected to the pad area PA of the substrate 111. Here, the flexible printed circuit board 130 may also be called a flexible printed circuit or circuit film. A printed circuit board 140 may be connected to the other side of the flexible printed circuit board 130.
[0044] The drive circuit 120 can be implemented as an integrated circuit. The drive circuit 120 may include a data drive circuit that supplies data signals corresponding to the video signal to the subpixels SP in the display panel 110.
[0045] The display device 100 according to embodiments of this disclosure may further include a gate drive circuit that supplies gate signals to subpixels SP in the display panel 110. In one example, the gate drive circuit may be located outside the display panel 110. In another example, the gate drive circuit may be located inside the display panel 110. A gate drive circuit located inside the display panel 110 is called a gate-in-panel (GIP) type and can be located on a substrate 111. A gate drive circuit located inside the display panel 110 can also be called a gate-in-panel circuit. For example, a gate-in-panel circuit can be located in a non-display area (NDA).
[0046] If the gate drive circuit is located outside the display panel 110, the gate drive circuit may be included in the drive circuit 120, or it may exist separately from the drive circuit 120.
[0047] The display device 100 according to the embodiments of this disclosure may further include a controller for controlling the drive circuit 120 and the gate drive circuit. For example, the controller may be mounted on a printed circuit board 140.
[0048] The display device 100 according to the embodiments of this disclosure may further include a non-display area (NDA) of the display panel 110 and a case member that covers the circuit configuration (e.g., a drive circuit 120, a flexible printed circuit board 130, and a printed circuit board 140). For example, the case member may include a mounting member that can be worn on the user's face (e.g., eyeglass temples, a headband, etc.).
[0049] On the other hand, for example, the display device 100 according to the embodiment of the present disclosure may have the shape of eyeglasses. For example, the display device 100 according to the embodiment of the present disclosure may be a heterogeneous integrated display device or an eyeglass-type wearable device. If the display device 100 according to the embodiment of the present disclosure is an eyeglass-type wearable device, the user can wear the display device 100 like eyeglasses. As a result, the waist region WA of the display device 100 can correspond to the position of the user's nose, and the upper edge line TEL of the upper region TOP and the lower edge line BEL of the lower region BOT can be adjacent to both of the user's ears.
[0050] For example, the display device 100 according to the embodiments of this disclosure may be at least one wearable device from among virtual reality (VR) devices, augmented reality (AR) devices, mixed reality (MR) devices, and extended reality (XR) devices. For example, if the display device 100 is a wearable device that can be worn on a user's face, the surface on which the image is displayed among the two surfaces of the display device 100 may be the surface opposite to the surface closer to the user wearing the display device 100. In this case, the image displayed on the display device 100 worn by the user can be shown to other users in the vicinity of the wearer. As another example, if the display device 100 is a wearable device that can be worn on a user's face, the surface on which the image is displayed among the two surfaces of the display device 100 may be the surface closer to the user wearing the display device 100. As another example, if the display device 100 is a wearable device that can be worn on the user's face, then of the two surfaces of the display device 100, the surface on which the image is displayed can be both the surface closer to the user wearing the display device 100 and the surface on the opposite side.
[0051] Figure 2 shows the equivalent circuit of a subpixel SP of the display panel 110 according to an embodiment of the present disclosure.
[0052] Each subpixel SP of the display device 100 according to the embodiments of this disclosure may include a light-emitting element ED and a subpixel circuit SPC for driving the light-emitting element ED.
[0053] The light-emitting element (ED) may be an organic-based organic light-emitting diode (OLED), an inorganic-based light-emitting diode (LED), or a quantum dot light-emitting element, but is not limited to these. For the sake of explanation, the following description will use the case where the light-emitting element (ED) is an organic light-emitting diode (OLED) as an example.
[0054] The subpixel circuit SPC may include multiple transistors for driving the light-emitting element ED and at least one capacitor. The subpixel circuit SPC can drive the light-emitting element ED by supplying a drive current to the light-emitting element ED at predetermined timings. The light-emitting element ED can emit light when driven by the drive current.
[0055] Multiple transistors included in the subpixel circuit SPC may include a drive transistor DT for driving the light-emitting element ED and a scan transistor ST that is turned on or off in response to a scan signal SC.
[0056] The drive transistor DT can supply drive current to the light-emitting element ED. The scan transistor ST can be configured to control the electrical state of the corresponding node in the subpixel circuit SPC, or to control the state or operation of the drive transistor DT. At least one capacitor may include a storage capacitor Cst to maintain a constant voltage between frames.
[0057] To drive the subpixel SP, a video signal such as the data signal Vdata and a type of gate signal such as the scan signal SC can be applied to the subpixel SP. Furthermore, a common drive signal, including the drive voltage VDD and base voltage VSS, can be applied to the subpixel SP.
[0058] The light-emitting element ED may include a pixel electrode PE, an intermediate layer EL, and a common electrode CE. The intermediate layer EL can be placed between the pixel electrode PE and the common electrode CE. For example, the pixel electrode PE may be an electrode placed in each subpixel SP, and the common electrode CE may be an electrode commonly placed in multiple subpixels SP. As an example, the pixel electrode PE may be the anode electrode and the common electrode CE may be the cathode electrode. As another example, the pixel electrode PE may be the cathode electrode and the common electrode CE may be the anode electrode. In the following explanation, for convenience, we will use the case where the pixel electrode PE is the anode electrode and the common electrode CE is the cathode electrode as an example.
[0059] If the light-emitting element ED is an organic light-emitting element, the intermediate layer EL may include a light-emitting layer EML, a first common intermediate layer COM1 between the pixel electrode PE and the light-emitting layer EML, and a second common intermediate layer COM2 between the light-emitting layer EML and the common electrode CE. The first common intermediate layer COM1 and the second common intermediate layer COM2 together can be called the common intermediate layer EL_COM.
[0060] The light-emitting layer (EML) can be placed for each subpixel SP, or it can be placed in common across multiple subpixel SPs, and the common intermediate layer (EL_COM) can also be placed in common across multiple subpixel SPs. However, it is not limited to these arrangements.
[0061] The light-emitting layer (EML) can be placed in each light-emitting region or in common across multiple light-emitting regions, and the common intermediate layer (EL_COM) can be placed in common across multiple light-emitting and non-light-emitting regions. However, it is not limited to these arrangements.
[0062] For example, the first common intermediate layer COM1 may include a hole injection layer (HIL), an electron blocking layer (EBL), and a hole transfer layer (HTL), and the second common intermediate layer COM2 may include an electron transfer layer (ETL), a hole blocking layer (HBL), and an electron injection layer (EIL), but is not limited thereto. The hole injection layer HIL injects holes from the pixel electrode PE to the hole transfer layer HTL, the hole transfer layer HTL transports holes to the light-emitting layer EML, the electron injection layer EIL injects electrons from the common electrode CE to the electron transfer layer ETL, and the electron transfer layer ETL transports electrons to the light-emitting layer EML.
[0063] For example, the common electrode CE can be electrically connected to the base voltage wiring VSSL. A base voltage VSS, which is a type of common voltage, can be applied to the common electrode CE via the base voltage wiring VSSL. The pixel electrode PE can be electrically connected directly or indirectly (via other transistors) to the first node Na of the drive transistor DT of each subpixel SP. In this disclosure, the base voltage VSS may also be referred to as the first common voltage, low potential power supply voltage, or low potential voltage, and the base voltage wiring VSSL may also be referred to as the first common voltage wiring, low potential power supply voltage line, or low potential voltage line.
[0064] Each light-emitting element ED can be composed of the superposition of a pixel electrode PE, an emissive layer EML within the intermediate layer EL, and a common electrode CE. Each light-emitting element ED can form a predetermined light-emitting region. For example, the light-emitting region of each light-emitting element ED may include the superposition of the pixel electrode PE, the emissive layer EML within the intermediate layer EL, and the common electrode CE.
[0065] The drive transistor DT may be a drive transistor for supplying drive current to the light-emitting element ED. The drive transistor DT may be connected between the drive voltage wiring VDDL and the light-emitting element ED.
[0066] The drive transistor DT may include a first node Na, a second node Nb, and a third node Nc. The first node Na may be electrically connected to the light-emitting element ED, the second node Nb may be to which a data signal Vdata is applied, and the third node Nc may be to which a drive voltage VDD, which is another type of common voltage, is applied from the drive voltage wiring VDDL. The drive transistor DT may be connected to the first node Na and the third node Nc. In this disclosure, the drive voltage VDD may also be referred to as the second common voltage, high potential power supply voltage, or high potential voltage, and the drive voltage wiring VDDL may also be referred to as the second common voltage wiring, low potential power supply voltage line, or low potential voltage line.
[0067] In a drive transistor DT, the second node Nb is the gate node, the first node Na is either the source node or the drain node, and the third node Nc may be either the drain node or the source node. For the sake of explanation, in the following, in a drive transistor DT, the second node Nb may be the gate node, the first node Na may be the source node, and the third node Nc may be the drain node. However, it is not limited to this.
[0068] The scan transistor ST included in the subpixel circuit SPC shown in Figure 2 may be a switching transistor that transmits the data signal Vdata, which is the video signal, to the second node Nb, which is the gate node of the drive transistor DT.
[0069] The scan transistor ST is controlled on / off by a scan signal SC, which is a type of gate signal applied via a scan line SCL, which is a type of gate line GL, and can control the electrical connection between the second node Nb of the drive transistor DT and the data line DL. The drain or source electrode of the scan transistor ST may be electrically connected to the data line DL, the source or drain electrode of the scan transistor ST may be electrically connected to the second node Nb of the drive transistor DT, and the gate electrode of the scan transistor ST may be electrically connected to the scan line SCL.
[0070] The storage capacitor Cst may be electrically connected between the first node Na and the second node Nb of the drive transistor DT. The storage capacitor Cst may include at least one capacitor electrode electrically connected to or corresponding to the first node Na of the drive transistor DT, and at least one capacitor electrode electrically connected to or corresponding to the second node Nb of the drive transistor DT.
[0071] The storage capacitor Cst may be an external capacitor intentionally designed outside the drive transistor DT, rather than a parasitic capacitor (e.g., Cgs, Cgd) which is an internal capacitor that may exist between the first node Na and the second node Nb of the drive transistor DT. However, it is not limited to this.
[0072] The drive transistor DT and the scan transistor ST may each be either an n-type or p-type transistor, but are not limited to this. For example, one of the drive transistor DT and scan transistor ST may be either an n-type or a p-type transistor.
[0073] The display panel 110 may have a top-emission structure or a bottom-emission structure. When the display panel 110 has a top-emission structure, at least a portion of the subpixel circuit SPC can overlap with at least a portion of the light-emitting element ED in the vertical direction. This can increase the area of the light-emitting region and improve the aperture ratio. When the display panel 110 has a bottom-emission structure, the subpixel circuit SPC does not need to overlap with the light-emitting element ED in the vertical direction.
[0074] The subpixel circuit SPC may have a 2T (Transistor) 1C (Capacitor) structure, as shown in Figure 2, which includes two transistors DT and ST and one capacitor Cst, and may optionally include one or more transistors or one or more capacitors.
[0075] The structure of the subpixel circuit SPC can affect the type and number of gate lines supplied to the subpixel SP. Furthermore, the structure of the subpixel circuit SPC can affect the type and number of common drive signals supplied to the subpixel SP.
[0076] Since the circuit elements within each subpixel SP (e.g., light-emitting elements ED, which are realized with organic light-emitting diodes (OLEDs) containing organic materials) are vulnerable to external moisture and oxygen, the display panel 110 may further include a sealing layer placed on the light-emitting elements ED. The sealing layer can prevent external moisture and oxygen from penetrating the circuit elements (e.g., light-emitting elements ED). The sealing layer can be configured in various forms to prevent the light-emitting elements ED from coming into contact with moisture and oxygen. For example, the sealing layer may consist of two or more layers in which organic and inorganic films are alternately stacked. However, it is not limited to this.
[0077] The display device 100 may further include a touch sensor layer on which a touch sensor is formed, and a touch sensing circuit that senses the touch sensor formed on the touch sensor layer and determines whether or not a touch is present or the touch coordinates, in order to provide a touch sensing function.
[0078] Figure 3 shows the data line arrangement structure of the display panel 110 according to an embodiment of the present disclosure. However, in the following description, Figures 1 and 2 will also be referred to.
[0079] The display panel 110 may include an upper region TOP, a lower region BOT, and an intermediate region MID between the upper region TOP and the lower region BOT. The upper region TOP may be the region to which circuit configurations (e.g., a drive circuit 120, a flexible printed circuit board 130, and a printed circuit board 140) are connected. The width BTW of the portion of the upper region TOP corresponding to the upper edge line TEL may be smaller than that of other portions.
[0080] The display panel 110 may include multiple data lines DL for transmitting data signals Vdata to multiple subpixels SP. Multiple data lines DL may be arranged in the display area DA.
[0081] Depending on the shape of the substrate 111 of the display panel 110 (for example, the shape of eyeglasses), the multiple data lines DL may include a plurality of first data lines DL1 that do not pass through the waist region WA, and a plurality of second data lines DL2 that pass through the waist region WA.
[0082] Each of the multiple first data lines DL1 can be connected to a first data link line DLL1 that extends from the pad area PA through the upper edge line TEL to the upper display area DA_TOP, and can be positioned extending in a first direction within the upper display area DA_TOP.
[0083] Each of the multiple first data lines DL1 can extend in the first direction and be positioned without curving in all of the upper display area DA_TOP, the middle display area DA_MID, and the lower display area DA_BOT.
[0084] Each of the multiple second data lines DL2 can be connected to a second data link line DLL2 that extends from the pad area PA through the upper edge line TEL to the upper display area DA_TOP, and can be positioned extending in the first direction within the upper display area DA_TOP.
[0085] However, each of the multiple second data lines DL2 can be positioned curved inward so that it is positioned on the inwardly recessed substrate 111 when passing through the waist region WA within the intermediate display region DA_MID.
[0086] If each of the multiple second data lines DL2 curves as it passes through the waist region WA, it can pass through the hidden region NDA contained within the waist region WA. As a result, each of the multiple second data lines DL2 may include an upper data line DL2_DA_TOP located in the upper display region DA_TOP, a lower data line DL2_DA_BOT located in the lower display region DA_BOT, and a bypass data line DL2_NDA that connects the upper data line DL1_DA_TOP and the lower data line DL2_DA_BOT and is located in the hidden region NDA.
[0087] As mentioned above, each of the multiple second data lines DL2 is positioned in a curved manner within the waist region WA, and as each of the bypass data lines DL2_NDA of the multiple second data lines DL2 is positioned within the hidden region NDA, the size of the hidden region NDA included in the waist region WA can increase.
[0088] Consequently, if the display device 100 according to the embodiment of this disclosure is a glasses-type wearable device, an increase in the size of the non-display area NDA included in the waist area WA may result in a decrease in the design quality of the display device 100 or make it inconvenient to wear the display device 100.
[0089] Figure 4 shows the detail area included in the waist area WA of the display panel 110 according to the embodiment of the present disclosure.
[0090] The hidden area NDA included in the waist area WA may include a data link area DLLA where multiple bypass data lines DL2_NDA of multiple second data lines DL2 are located, a drive power wiring area PLA where drive power wiring is located, a gate-in-panel circuit area GIPA where a gate-in-panel circuit, which is a gate-in-panel type gate drive circuit, is located, a base voltage wiring area VSSA where base voltage wiring VSSL is located, and a crack stopper area CSA where crack stopper structures are located.
[0091] The drive power supply wiring area PLA can accommodate gate drive-related link wiring connected to the gate in-panel circuit, and drive power supply wiring for transmitting various drive power supplies (e.g., initialization voltage, reference voltage, etc.) to the subpixel SP.
[0092] The non-display area NDA included in the waist area WA may further include a connection area CLA where the drive power wiring located in the drive power wiring area PLA is extended and gate lines are located to transmit gate signals output from the gate-in-panel circuit to the subpixel SP.
[0093] The non-display area NDA included in the waist area WA may further include a first empty space FA1 between the base voltage wiring area VSSA and the crack stopper area CSA, and a second empty space FA2 between the crack stopper area CSA and the trimming line. Here, the trimming line may correspond to the cutting line of the substrate 111.
[0094] As mentioned above, each of the multiple second data lines DL2 is positioned curvingly in the waist region WA, and as the bypass data line DL2_NDA of each of the multiple second data lines DL2 is positioned in the hidden region NDA, the hidden region NDA contained in the waist region WA can contain a larger data link region DLLA.
[0095] Figure 5 is a cross-sectional view of the display panel 110 according to an embodiment of the present disclosure. Figure 5 is a cross-sectional view taken along the XY lines of Figure 3.
[0096] The display panel 110 according to the embodiments of this disclosure may include a display area DA and a non-display area NDA.
[0097] The display panel 110 according to the embodiments of this disclosure may include a substrate 111, a buffer layer 520 disposed on the substrate 111, a gate insulating layer 530 disposed on the buffer layer 520, an interlayer insulating layer 540 disposed on the gate insulating layer 530, a planarizing layer 550 disposed on the interlayer insulating layer 540, a light-emitting element ED disposed on the planarizing layer 550 and located in the display area DA, and a sealing layer 580 disposed on the light-emitting element ED.
[0098] The substrate 111 may be single-layer or multilayer. If the substrate 111 is multilayer, it may include a first substrate 301, an intermediate substrate layer 302, and a second substrate 303. The intermediate substrate layer 302 may be located between the first substrate 301 and the second substrate 303. For example, the first substrate 301 and the second substrate 303 may each be polyimide (PI) layers, but are not limited thereto. The intermediate substrate layer 302 may also be an inorganic insulating layer, but are not limited thereto. The intermediate substrate layer 302 can block the charge from affecting the transistors located on the second substrate 303 via the polyimide layer of the second substrate 303 when the first substrate 301, which is a polyimide layer, is charged.
[0099] Furthermore, the intermediate substrate layer 302 can block moisture components from penetrating the first substrate 301 and permeating to the upper layer. For example, the intermediate substrate layer 302 can consist of a single layer or multiple layers of silicon nitride (SiNx) or silicon oxide (SiOx), or it can be formed from a bilayer of silicon dioxide (SiO2) and silicon nitride (SiNx). However, it is not limited to these.
[0100] The buffer layer 520 may be single-layer or multi-layer, but is not limited to this. If the buffer layer 520 is multi-layer, it may include a first buffer layer 521 and a second buffer layer 522.
[0101] The display panel 110 may further include a transistor TFT and a storage capacitor Cst, which are arranged on the buffer layer 520. The transistor TFT may include an active layer ACT, a gate electrode G, a source electrode S, and a drain electrode D. The storage capacitor Cst may include a first capacitor electrode CAPE1 and a second capacitor electrode CAPE2.
[0102] The active layer ACT of the transistor TFT is placed on the buffer layer 520, and the gate insulating layer 530 may be placed on the active layer ACT of the transistor TFT.
[0103] The gate electrode G of the transistor TFT is located on the gate insulating layer 530 and can overlap with at least a portion of the active layer ACT.
[0104] The interlayer insulating layer 540 may include a first interlayer insulating layer 541 and a second interlayer insulating layer 542. The first interlayer insulating layer 541 may be placed on the gate electrode G of a transistor TFT. The second interlayer insulating layer 542 may be placed on the first interlayer insulating layer 541.
[0105] The source electrode S and drain electrode D of the transistor TFT can be placed on the second interlayer insulating layer 542. The source electrode S of the transistor TFT can be connected to a portion of the active layer ACT through holes in the second interlayer insulating layer 542 and the first interlayer insulating layer 541, and the drain electrode D of the transistor TFT can be connected to another portion of the active layer ACT of the transistor TFT through other holes in the second interlayer insulating layer 542 and the first interlayer insulating layer 541.
[0106] The first capacitor electrode CAPE1 can be placed on the gate insulating layer 530, and the second capacitor electrode CAPE2 can be placed on the first interlayer insulating layer 541 and superimposed on the first capacitor electrode CAPE1.
[0107] The first capacitor electrode CAPE1 can be placed in the same metal layer as the gate electrode G of the transistor TFT, and the second capacitor electrode CAPE2 can be placed between the gate electrode G of the transistor TFT and the source electrode S / drain electrode D.
[0108] The planarization layer 550 can be placed on the second interlayer insulating layer 542.
[0109] The light-emitting element ED can be placed on the planarization layer 550 and may include a pixel electrode PE, an intermediate layer EL, and a common electrode CE.
[0110] The pixel electrode PE is placed on the planarization layer 550 and can be electrically connected to the source electrode S or drain electrode D of the transistor TFT through holes in the planarization layer 550.
[0111] Bank 560 is positioned on the planarization layer 550 and the pixel electrode PE, but may have light-emitting holes EH that expose a portion of the pixel electrode PE. The light-emitting holes EH of bank 560 may correspond to the light-emitting region of the light-emitting element ED.
[0112] The intermediate layer EL can be positioned on bank 560, in contact with the upper surface of the pixel electrode PE within the light-emitting hole EH of bank 560.
[0113] The common electrode CE can be placed on the intermediate layer EL.
[0114] The sealing layer 580 can be placed on the common electrode CE. The sealing layer 580 may include a first sealing layer 581, a second sealing layer 582, and a third sealing layer 583. The first sealing layer 581 and the third sealing layer 583 may be inorganic layers, and the second sealing layer 582 may be an organic layer.
[0115] The display panel 110 may further include a first dam DAM1 positioned outside the second sealing layer 582. For example, the first dam DAM1 may include a plurality of dam constituent layers 550a, 560a, and 570a. For example, the plurality of dam constituent layers 550a, 560a, and 570a may include a first dam constituent layer 550a, a second dam constituent layer 560a, and a third dam constituent layer 570a. The first dam constituent layer 550a may contain the same organic insulating material as the flattening layer 550, the second dam constituent layer 560a may contain the same organic insulating material as the bank 560, and the third dam constituent layer 570a may contain the same organic insulating material as the spacer that can be placed on the bank 560.
[0116] The display panel 110 may further include a second dam DAM2 located outside the first dam DAM1. For example, the second dam DAM2 may include multiple dam layers 550a, 560a, and 570a, similar to the first dam DAM1.
[0117] The first sealing layer 581 is positioned on the common electrode CE, but may extend beyond the top of the first dam DAM1 and the second dam DAM2 to the outside of the second dam DAM2.
[0118] The third sealing layer 583 is positioned on the second sealing layer 582, but extends outward beyond the second sealing layer 582, and together with the first sealing layer 581, can extend over the tops of the first dam DAM1 and the second dam DAM2, extending to the outside of the second dam DAM2. As a result, the second sealing layer 582 is absent on the first dam DAM1 and the second dam DAM2, and the first sealing layer 581 and the third sealing layer 583 can be positioned on the structures of the first dam DAM1 and the second dam DAM2 in contact with each other.
[0119] The display panel 110 may further include a base voltage wiring VSSL to which the base voltage VSS is applied, and a connection pattern CP that electrically connects the common electrode CE and the base voltage wiring VSSL.
[0120] The base voltage wiring VSSL can be placed between the second interlayer insulation layer 542 and the planarization layer 550. The base voltage wiring VSSL can be placed below the planarization layer 550 and can extend below the first dam DAM1.
[0121] The connection pattern CP can be positioned between bank 560 and planarization layer 550. For example, the connection pattern CP can be located in a non-display area NDA. The connection pattern CP can extend from the top surface of planarization layer 550 along the side surface of planarization layer 550 and be electrically connected to the base voltage wiring VSSL.
[0122] Bank 560 may have additional connection holes CH. For example, the connection holes CH of Bank 560 may be located in a hidden area NDA.
[0123] The common electrode CE can be extended from the display area DA to a portion of the non-display area NDA. In the non-display area NDA, the common electrode CE can be electrically connected to the upper surface of the connection pattern CP via the connection hole CH of bank 560.
[0124] The display panel 110 may further include a lower shielding metal BSM that overlaps with the active layer ACT of the transistor TFT. The lower shielding metal BSM may be located between the substrate 111 and the buffer layer 520, or between the first buffer layer 521 and the second buffer layer 522.
[0125] The display panel 110 can include various metal layers. For example, the display panel 110 can include a lower shield metal layer BSML on which the lower shield metal BSM is located, a gate metal layer GML on which the gate electrode G of the transistor TFT and the first capacitor electrode CAPE1 of the storage capacitor Cst are located, a capacitor electrode metal layer TML on which the second capacitor electrode CAPE2 of the storage capacitor Cst is located, a source-drain metal layer SDML on which the source electrode S and drain electrode D of the transistor TFT are located, a pixel electrode metal layer PEML on which the pixel electrode PE is located, and a common electrode metal layer CEML on which the common electrode CE is located.
[0126] On the other hand, as described above with reference to Figures 3 and 4, the shape of the display panel 110 allows the size of the non-display area NDA included in the waist area WA to increase as data lines (bypass data lines) to which data signals are applied are arranged. As a result, if the display device 100 according to the embodiment of this disclosure is a glasses-type wearable device, the design quality of the display device 100 may be reduced or the display device 100 may become inconvenient to wear.
[0127] Therefore, embodiments of the present disclosure can provide a "bezel-reducing data link structure" that can reduce the size of the non-display area NDA included in the waist area WA of the display panel 110. Embodiments of the present disclosure can provide a power wiring structure that can improve display driving performance. Embodiments of the present disclosure can provide a power wiring structure linked to the bezel-reducing data link structure.
[0128] The following describes a signal structure that enables bezel reduction according to embodiments of the present disclosure. However, the following description will also refer to Figures 1 to 5.
[0129] Figures 6 and 7 show a data line arrangement structure that enables bezel reduction of the display panel 110 according to an embodiment of the present disclosure.
[0130] Referring to Figures 6 and 7, the display panel 110 according to the embodiment of the present disclosure may include a substrate 111 that includes a display area DA capable of displaying video and a non-display area NDA outside the display area DA, and N data lines arranged on the substrate 111.
[0131] For example, the substrate 111 may include first to fifth regions A1, A2, A3, A4, and A5 that are sequentially located in the first direction.
[0132] For example, display area DA can include the first to fifth display areas DA1, DA2, DA3, DA4, and DA5, which are contained within the first to fifth areas A1, A2, A3, A4, and A5, respectively. That is, the first area A1 can include the first display area DA1, the second area A2 can include the second display area DA2, the third area A3 can include the third display area DA3, the fourth area A4 can include the fourth display area DA4, and the fifth area A5 can include the fifth display area DA5.
[0133] The first to fifth regions A1, A2, A3, A4, and A5 can exist between the upper edge line TEL and the lower edge line BEL.
[0134] The first region A1 may be the region between the upper edge line TEL and the first boundary line BL12. The first boundary line BL12 may be the boundary between the first region A1 and the second region A2. The first region A1 may be the region that includes the pad region PA.
[0135] The second region A2 may be the region between the first boundary line BL12 and the second boundary line BL23. The second boundary line BL23 may be the boundary between the second region A2 and the third region A3.
[0136] The third region A3 may be the region between the second boundary line BL23 and the third boundary line BL34. The third boundary line BL34 may be the boundary between the third region A3 and the fourth region A4.
[0137] The fourth region A4 may be the region between the third boundary line BL34 and the fourth boundary line BL45. The fourth boundary line BL45 may be the boundary between the fourth region A4 and the fifth region A5.
[0138] The fifth region A5 may be the region between the fourth boundary line BL45 and the lower edge line BEL.
[0139] The third region A3 may include the third display region DA3, the first non-display region NDA1 on one side of the third display region DA3, and the second non-display region NDA2 on the other side of the third display region DA3. The third region A3 may include a waist area (WA) that is indented inward on one side.
[0140] At the second boundary line BL23 between the second region A2 and the third region A3, the width of the third region A3 may narrow as it approaches the center of the third region A3. Similarly, at the third boundary line BL34 between the fourth region A4 and the third region A3, the width of the third region A3 may narrow as it approaches the center of the third region A3.
[0141] One side of the third region A3 may include a waist area (WA) where the edge line of the substrate 111 is recessed inward. The other side of the third region A3 is opposite the waist area WA and may include a back area (BA) where the edge line of the substrate 111 is convex or flat.
[0142] The waist region WA may include a third display region DA3 and a first non-display region NDA1 outside of it (e.g., left outer), and the back region BA may include a third display region DA3 and a second non-display region NDA2 outside of it (e.g., right outer).
[0143] Referring to Figure 6, each of the N data lines can pass through all of the first to fifth regions A1, A2, A3, A4, and A5. As a result, each of the first to fifth regions A1, A2, A3, A4, and A5 can contain N data lines.
[0144] For example, in the first region A1, all N data lines can pass through the first display region DA1. In the fifth region A5, all N data lines can pass through the fifth display region DA5.
[0145] In one example, in the second region A2, all N data lines can pass through the second display region DA2. In another example, in the second region A2, some of the N data lines can pass through the second display region DA2, while others can pass through the hidden region NDA outside the second display region DA2 (for example, to the right).
[0146] In one example, in the fourth region A4, all N data lines can pass through the fourth display region DA4. In another example, in the fourth region A4, some of the N data lines can pass through the fourth display region DA4, while the other parts can pass through the non-display region NDA outside the fourth display region DA4 (for example, to the right).
[0147] For example, in the third region A3, some of the N data lines (e.g., M3 data lines) can pass through the third display region DA3, another portion (e.g., M1 data lines) can pass through the first non-display region NDA1 outside the third display region DA3 (e.g., left outer), and yet another portion (e.g., M2 data lines) can pass through the second non-display region NDA2 outside the third display region DA3 (e.g., right outer).
[0148] For example, N data lines may include M1 data lines passing through the first hidden area NDA1 within the third area A3, M2 data lines passing through the second hidden area NDA2 within the third area A3, and M3 data lines passing through the third visible area DA3 within the third area A3.
[0149] M3 data lines can pass only through the third display area DA3 within the third area A3, without passing through the first non-display area NDA1 and the second non-display area NDA2, which are included in the third area A3.
[0150] According to the display panel 110 of the embodiment of this disclosure, N is the total number of data lines arranged on the display panel 110 and may be a natural number of 3 or more. M1 is the total number of data lines passing through the first non-display area NDA1 in the third area A3 and may be a natural number of 1 or more. M2 is the total number of data lines passing through the second non-display area NDA2 in the third area A3 and may be a natural number of 1 or more. M3 is the total number of data lines passing through only the third display area DA3 among the first non-display area NDA1, the third display area DA3, and the second non-display area NDA2 included in the third area A3 and may be a natural number of 1 or more.
[0151] According to the display panel 110 in the embodiment of this disclosure, the sum of M1, M2, and M3 may correspond to N.
[0152] Due to the shape of the display device 100 according to the embodiment of this disclosure (for example, the shape of eyeglasses), the third region A3 has a narrower width (maximum width) than the first, second, fourth, and fifth regions A1, A2, A4, and A5, so that all N (N=M1+M2+M3) data lines cannot be placed in the third display region DA3 within the third region A3.
[0153] For example, depending on the shape of the display device 100 according to the embodiment of this disclosure (e.g., the shape of eyeglasses), out of N (N=M1+M2+M3) data lines, only M3 data lines can pass through the third display area DA3 within the third area A3, and (M1+M2) data lines cannot pass through the third display area DA3 within the third area A3.
[0154] In this case, if all (M1+M2) data lines that cannot pass through the third display area DA3 within the third area A3 pass through the first hidden area NDA1 within the third area A3, the size of the first hidden area NDA1 can only increase.
[0155] However, according to the display device 100 of the embodiment of this disclosure, a portion of the (M1+M2) data lines (M1 data lines) can pass through the first non-display area NDA1 in the third area A3, and the other portion (M2 data lines) can pass through the second non-display area NDA2 in the third area A3, thereby preventing the size of the first non-display area NDA1 from becoming excessively large.
[0156] The display panel 110 may further include multiple subpixels SP arranged in the display area DA. Figure 7 illustrates an example where five data lines DL1, DL2, DL3, DL4, and DL5 are arranged in the display panel 110, and of the five data lines DL1, DL2, DL3, DL4, and DL5, the first data line DL1 passes through the first non-display area NDA1 in the third area A3, the fifth data line DL5 passes through the second non-display area NDA2 in the third area A3, and the second to fourth data lines DL2, DL3, and DL4 pass through the third display area DA3 in the third area A3 (i.e., N=5, M1=1, M2=1, M3=3).
[0157] Multiple subpixels SP are arranged in the first display area DA1 within the first region A1 and connected to the first gate line GL1, consisting of N1 subpixels (e.g., SP1_1, SP1_2, SP1_3, SP1_4, SP1_5), in the second display area DA2 within the second region A2 and connected to the second gate line GL2, and in the third display area DA3 within the third region A3. It may include N3 subpixels connected to the third gate line GL3 (e.g., SP3_2, SP3_3, SP3_4), N4 subpixels located in the fourth display area DA4 within the fourth region A4 and connected to the fourth gate line GL4 (e.g., SP4_1, SP4_2, SP4_3, SP4_4), and N5 subpixels located in the fifth display area DA5 within the fifth region A5 and connected to the fifth gate line GL5 (e.g., SP5_1, SP5_2, SP5_3, SP5_4, SP5_5).
[0158] In the display panel 110 according to the embodiment of this disclosure, N3 may be the minimum value among N1, N2, N3, N4, and N5. N3 may be a natural number of 1 or more. As a result, the number of pixels in the third display area DA3 may be small.
[0159] According to the display panel 110 of the embodiment of this disclosure, N1 and N5 may each be the same as N (N1=N5=N). N2 and N4 may each be less than or equal to N (N2≦N, N4≦N). N3 may be less than or equal to N2 or N4 (N3≦N2, or N3≦N4).
[0160] According to the display panel 110 of the embodiment of this disclosure, N3 may be the same as M3, and (N1~N3) may be (M1+M2).
[0161] Referring to Figure 7, M1 data lines passing through the first hidden area NDA1 within the third area A3 may include the first data line DL1.
[0162] N1 subpixels may include a first subpixel SP1_1 connected to the first data line DL1. N2 subpixels may include a second subpixel SP2_1 located diagonally to the right (down-right diagonally) from the first subpixel SP1_1 and connected to the first data line DL1. N4 subpixels may include a fourth subpixel SP4_1 connected to the first data line DL1. N5 subpixels may include a fifth subpixel SP5_1 located diagonally to the left (down-left diagonally) from the fourth subpixel SP4_1 and connected to the first data line DL1.
[0163] Referring to Figures 6 and 7, the second region A2 may be a right-shifted region where the data transmission path is shifted away from the waist region WA (to the right in the example of Figures 6 and 7). The fourth region A4 may be a left-shifted region where the data transmission path is shifted towards the waist region WA (to the left in the example of Figures 6 and 7).
[0164] Referring to Figure 7, the first data line DL1 can be bent or curved in the second display area DA2 within the second area A2. The first data line DL1 can be bent or curved in the fourth display area DA4 within the fourth area A4. For example, in the third area A3, one edge of the substrate 111 is recessed inward, and the first data line DL1 may be bent or curved in one direction (e.g., to the right) in the second display area DA2 within the second area A2, and may be bent or curved in the other direction (e.g., to the left) in the fourth display area DA4 within the fourth area A4.
[0165] The first data line DL1 can be positioned along the inwardly recessed edge of the substrate 111 as it passes through the first non-display area NDA1 within the third area A3.
[0166] The first subpixel SP1_1, the second subpixel SP2_1, the fourth subpixel SP4_1, and the fifth subpixel SP5_1 can all be connected to the first data line DL1. However, the second and fourth subpixels SP2_1 and SP4_1 located in the second and fourth display areas DA2 and DA4 may be located in different columns than the first and fifth subpixels SP1_1 and SP5_1 located in the first and fifth display areas DA1 and DA5.
[0167] The first subpixel SP1_1, the second subpixel SP2_1, the fourth subpixel SP4_1, and the fifth subpixel SP5_1 can all emit light of the same color. As mentioned above, since data signals are sequentially supplied to subpixels emitting light of the same color via the first data line DL1, data rendering, which requires adjusting data for each color, is not necessary. This improves data driving efficiency.
[0168] Referring to Figure 7, the M3 data lines passing through the third display area DA3 within the third area A3 can include the second to fourth data lines DL2, DL3, and DL4. Below, the arrangement structure and subpixel connection structure of the second to fourth data lines DL2, DL3, and DL4 will be described as representatively using the arrangement structure and subpixel connection structure of the second data line DL2.
[0169] N1 subpixels can include a sixth subpixel SP1_2 connected to the second data line DL2. N2 subpixels can include a seventh subpixel SP2_2 located diagonally to the right (down-right diagonally) from the sixth subpixel SP1_2 and connected to the second data line DL2. N3 subpixels can include an eighth subpixel SP3_2 located in the first direction from the seventh subpixel SP2_2 and connected to the second data line DL2. N4 subpixels can include a ninth subpixel SP4_2 located in the first direction from the eighth subpixel SP3_2 and connected to the second data line DL2. N5 subpixels can include a tenth subpixel SP5_2 located diagonally to the left (down-left diagonally) from the ninth subpixel SP4_2 and connected to the second data line DL2.
[0170] The second data line DL2 may be bent or curved in the second display area DA2 within the second area A2. The second data line DL2 may be bent or curved in the fourth display area DA4 within the fourth area A4. For example, in the third area A3, one edge of the substrate 111 is recessed inward, and the second data line DL2 may be bent or curved in one direction (e.g., to the right) in the second display area DA2 within the second area A2, and may be bent or curved in the other direction (e.g., to the left) in the fourth display area DA4 within the fourth area A4.
[0171] The second data line DL2 can pass through the third display area DA3 within the third area A3 in the first direction.
[0172] The sixth subpixel SP1_2, the seventh subpixel SP2_2, the eighth subpixel SP3_2, the ninth subpixel SP4_2, and the tenth subpixel SP5_2 can all be connected to the second data line DL2. However, the seventh to ninth subpixels SP2_2, SP3_2, and SP4_2 located in the second to fourth display areas DA2, DA3, and DA4 may be located in different columns from the sixth and tenth subpixels SP1_2 and SP5_2 located in the first and fifth display areas DA1 and DA5.
[0173] The sixth subpixel SP1_2, the seventh subpixel SP2_2, the eighth subpixel SP3_2, the ninth subpixel SP4_2, and the tenth subpixel SP5_2 can all emit light of the same color. As mentioned above, since data signals are sequentially supplied to subpixels that emit light of the same color via the second data line DL2, data rendering, which requires adjusting data for each color, is not necessary. This improves data driving efficiency.
[0174] Referring to Figure 7, the M2 data lines passing through the second hidden area NDA2 within the third area A3 may include a fifth data line DL5.
[0175] The fifth data line DL5 may be bent or curved in the second display area DA2 within the second area A2, and may be bent or curved in the fourth display area DA4 within the fourth area A4. For example, in the third area A3, one edge of the substrate 111 is recessed inward, and the fifth data line DL5 may be bent or curved in one direction (e.g., to the right) in the second display area DA2 within the second area A2, and may be bent or curved in the other direction (e.g., to the left) in the fourth display area DA4 within the fourth area A4.
[0176] N1 subpixels can include an eleventh subpixel SP1_5 connected to the fifth data line DL5. N5 subpixels can include a fifteenth subpixel SP5_5 connected to the fifth data line DL5.
[0177] The fifth data line DL5 can be positioned along the edge of the substrate 111 as it passes through the second non-display area NDA2 within the third area A3.
[0178] Both the 11th subpixel SP1_5 and the 15th subpixel SP5_5 can be connected to the 5th data line DL5.
[0179] Both the 11th subpixel SP1_5 and the 15th subpixel SP5_5 can emit light of the same color. Since data signals are sequentially supplied to the subpixels SP1_5 and SP5_5 that emit light of the same color via the 5th data line DL5, data rendering, which requires adjusting color-specific data, is not necessary. This improves data driving efficiency.

Here, the drive voltage line VDDL may also be called a high-potential voltage line or a first common voltage line, and the base voltage line VSSL may also be called a low-potential voltage line or a second common voltage line. The type of the first power supply line PL1 and the second power supply line PL2 may vary depending on the structure of the subpixel SP. For example, the first power supply line PL1 and the second power supply line PL2 may each be an initialization voltage line for transmitting an initialization voltage to any node in the subpixel SP, or a reset voltage line for transmitting a reset voltage to a pixel electrode PE in the subpixel SP.
[0241] Referring to Figures 12 and 13, multiple power supply lines PL can be arranged within the first metal layer ML1 together with line parts DL1a, DL1c, DL1e, DL1g corresponding to the wiring in the first direction of the first data line DL1.
